4 == Preamble: referenced user accounts ==
6 In subsequent sections, we will refer to a number of different accounts, as
10 ** The *user* Linux account is the account that you use to log onto the
11 Linux system as a regular user.
12 ** The *root* Linux account is an account that has system administrator
13 privileges. On Debian you can switch to this account from
14 your *user* account by issuing the `su -` command and entering the
15 password for the *root* account when prompted. On Ubuntu you can switch
16 to this account from your *user* account using the `sudo su -` command
17 and entering the password for your *user* account when prompted.
18 ** The *opensrf* Linux account is an account that you create when installing
19 OpenSRF. You can switch to this account from the *root* account by
20 issuing the `su - opensrf` command.
21 ** The *postgres* Linux account is created automatically when you install
22 the PostgreSQL database server. You can switch to this account from the
23 *root* account by issuing the `su - postgres` command.
24 * PostgreSQL user accounts:
25 ** The *evergreen* PostgreSQL account is a superuser account that you will
26 create to connect to the PostgreSQL database server.
27 * Evergreen administrator account:
28 ** The *egadmin* Evergreen account is an administrator account for
29 Evergreen that you will use to test connectivity and configure your

35 Skip this section if you are using an official release tarball downloaded
36 from http://evergreen-ils.org/egdownloads
38 Developers working directly with the source code from the Git repository,
39 rather than an official release tarball, must perform one step before they
40 can proceed with the `./configure` step.
42 As the *user* Linux account, issue the following command in the Evergreen
43 source directory to generate the configure script and Makefiles:
46 ------------------------------------------------------------------------------
48 ------------------------------------------------------------------------------
50 == Installing prerequisites ==
52 * **PostgreSQL**: The minimum supported version is 9.6.
53 * **Linux**: Evergreen has been tested on
57 Ubuntu Bionic Beaver (18.04),
58 and Ubuntu Xenial Xerus (16.04).
59 If you are running an older version of these distributions, you may want
60 to upgrade before upgrading Evergreen. For instructions on upgrading these
61 distributions, visit the Debian or Ubuntu websites.
62 * **OpenSRF**: The minimum supported version of OpenSRF is 3.2.0.
65 Evergreen has a number of prerequisite packages that must be installed
66 before you can successfully configure, compile, and install Evergreen.
68 1. Begin by installing the most recent version of OpenSRF (3.2.0 or later).
69 You can download OpenSRF releases from http://evergreen-ils.org/opensrf-downloads/
71 2. Issue the following commands as the *root* Linux account to install
72 prerequisites using the `Makefile.install` prerequisite installer,
73 substituting `debian-buster`,`debian-stretch`,`debian-jessie`,`ubuntu-bionic`, or
74 `ubuntu-xenial` for <osname> below:
77 ------------------------------------------------------------------------------
78 make -f Open-ILS/src/extras/Makefile.install <osname>
79 ------------------------------------------------------------------------------
81 [#optional_developer_additions]
82 3. OPTIONAL: Developer additions
84 To perform certain developer tasks from a Git source code checkout,
85 including the testing of the Angular web client components,
86 additional packages may be required. As the *root* Linux account:
88 * To install packages needed for retrieving and managing web dependencies,
89 use the <osname>-developer Makefile.install target. Currently,
90 this is only needed for building and installing the web
94 ------------------------------------------------------------------------------
95 make -f Open-ILS/src/extras/Makefile.install <osname>-developer
96 ------------------------------------------------------------------------------
98 * To install packages required for building Evergreen translations, use
99 the <osname>-translator Makefile.install target.
102 ------------------------------------------------------------------------------
103 make -f Open-ILS/src/extras/Makefile.install <osname>-translator
104 ------------------------------------------------------------------------------
106 * To install packages required for building Evergreen release bundles, use
107 the <osname>-packager Makefile.install target.
110 ------------------------------------------------------------------------------
111 make -f Open-ILS/src/extras/Makefile.install <osname>-packager
112 ------------------------------------------------------------------------------
114 == Extra steps for web staff client ==
117 Skip this entire section if you are using an official release tarball downloaded
118 from http://evergreen-ils.org/downloads. Otherwise, ensure you have installed the
119 xref:#optional_developer_additions[optional developer additions] before proceeding.
121 [[install_files_for_web_staff_client]]
122 === Install AngularJS files for web staff client ===
124 1. Building, Testing, Minification: The remaining steps all take place within
125 the staff JS web root:
128 ------------------------------------------------------------------------------
129 cd $EVERGREEN_ROOT/Open-ILS/web/js/ui/default/staff/
130 ------------------------------------------------------------------------------
132 2. Install Project-local Dependencies. npm inspects the 'package.json' file
133 for dependencies and fetches them from the Node package network.
136 ------------------------------------------------------------------------------
137 npm install # fetch JS dependencies
138 ------------------------------------------------------------------------------
140 3. Run the build script.
143 ------------------------------------------------------------------------------
144 # build, concat+minify
146 ------------------------------------------------------------------------------
148 4. OPTIONAL: Test web client code if the <osname>-developer packages were installed.
149 CHROME_BIN should be set to the path to chrome or chromimum, e.g.,
153 ------------------------------------------------------------------------------
154 CHROME_BIN=/path/to/chrome npm run test
155 ------------------------------------------------------------------------------
157 [[install_files_for_angular_web_staff_client]]
158 === Install Angular files for web staff client ===
160 1. Building, Testing, Minification: The remaining steps all take place within
161 the Angular staff root:
164 ------------------------------------------------------------------------------
165 cd $EVERGREEN_ROOT/Open-ILS/src/eg2/
166 ------------------------------------------------------------------------------
168 2. Install Project-local Dependencies. npm inspects the 'package.json' file
169 for dependencies and fetches them from the Node package network.
172 ------------------------------------------------------------------------------
173 npm install # fetch JS dependencies
174 ------------------------------------------------------------------------------
176 3. Run the build script.
179 ------------------------------------------------------------------------------
180 # build and run tests
182 ------------------------------------------------------------------------------
184 4. OPTIONAL: Test eg2 web client code if the <osname>-developer packages were installed:
185 CHROME_BIN should be set to the path to chrome or chromimum, e.g.,
189 ------------------------------------------------------------------------------
190 CHROME_BIN=/path/to/chrome npm run test
191 ------------------------------------------------------------------------------
193 == Configuration and compilation instructions ==
195 For the time being, we are still installing everything in the `/openils/`
196 directory. From the Evergreen source directory, issue the following commands as
197 the *user* Linux account to configure and build Evergreen:
200 ------------------------------------------------------------------------------
201 PATH=/openils/bin:$PATH ./configure --prefix=/openils --sysconfdir=/openils/conf
203 ------------------------------------------------------------------------------
205 These instructions assume that you have also installed OpenSRF under `/openils/`.
206 If not, please adjust PATH as needed so that the Evergreen `configure` script
207 can find `osrf_config`.
209 == Installation instructions ==
211 1. Once you have configured and compiled Evergreen, issue the following
212 command as the *root* Linux account to install Evergreen and copy
213 example configuration files to `/openils/conf`.
216 ------------------------------------------------------------------------------
218 ------------------------------------------------------------------------------
220 == Change ownership of the Evergreen files ==
222 All files in the `/openils/` directory and subdirectories must be owned by the
223 `opensrf` user. Issue the following command as the *root* Linux account to
224 change the ownership on the files:
227 ------------------------------------------------------------------------------
228 chown -R opensrf:opensrf /openils
229 ------------------------------------------------------------------------------
233 On Ubuntu 18.04 or Debian Stretch / Buster, run the following command as the root user:
236 ------------------------------------------------------------------------------
238 ------------------------------------------------------------------------------
240 == Additional Instructions for Developers ==
243 Skip this section if you are using an official release tarball downloaded
244 from http://evergreen-ils.org/egdownloads
246 Developers working directly with the source code from the Git repository,
247 rather than an official release tarball, need to install the Dojo Toolkit
248 set of JavaScript libraries. The appropriate version of Dojo is included in
249 Evergreen release tarballs. Developers should install the Dojo 1.3.3 version
250 of Dojo by issuing the following commands as the *opensrf* Linux account:
253 ------------------------------------------------------------------------------
254 wget http://download.dojotoolkit.org/release-1.3.3/dojo-release-1.3.3.tar.gz
255 tar -C /openils/var/web/js -xzf dojo-release-1.3.3.tar.gz
256 cp -r /openils/var/web/js/dojo-release-1.3.3/* /openils/var/web/js/dojo/.
257 ------------------------------------------------------------------------------
260 == Configure the Apache Web server ==
262 . Use the example configuration files to configure your Web server for
263 the Evergreen catalog, web staff client, Web services, and administration
264 interfaces. Issue the following commands as the *root* Linux account:
267 ------------------------------------------------------------------------------------
268 cp Open-ILS/examples/apache_24/eg_24.conf /etc/apache2/sites-available/eg.conf
269 cp Open-ILS/examples/apache_24/eg_vhost_24.conf /etc/apache2/eg_vhost.conf
270 cp Open-ILS/examples/apache_24/eg_startup /etc/apache2/
272 mkdir /etc/apache2/ssl
274 ------------------------------------------------------------------------------------
276 . The `openssl` command cuts a new SSL key for your Apache server. For a
277 production server, you should purchase a signed SSL certificate, but you can
278 just use a self-signed certificate and accept the warnings in the
279 and browser during testing and development. Create an SSL key for the Apache
280 server by issuing the following command as the *root* Linux account:
283 ------------------------------------------------------------------------------
284 openssl req -new -x509 -days 365 -nodes -out server.crt -keyout server.key
285 ------------------------------------------------------------------------------
287 . As the *root* Linux account, edit the `eg.conf` file that you copied into
289 a. To enable access to the offline upload / execute interface from any
290 workstation on any network, make the following change (and note that
291 you *must* secure this for a production instance):
292 * Replace `Require host 10.0.0.0/8` with `Require all granted`
293 . Change the user for the Apache server.
294 * As the *root* Linux account, edit
295 `/etc/apache2/envvars`. Change `export APACHE_RUN_USER=www-data` to
296 `export APACHE_RUN_USER=opensrf`.
297 . As the *root* Linux account, configure Apache with KeepAlive settings
298 appropriate for Evergreen. Higher values can improve the performance of a
299 single client by allowing multiple requests to be sent over the same TCP
300 connection, but increase the risk of using up all available Apache child
301 processes and memory.
302 * Edit `/etc/apache2/apache2.conf`.
303 a. Change `KeepAliveTimeout` to `1`.
304 b. Change `MaxKeepAliveRequests` to `100`.
305 . As the *root* Linux account, configure the prefork module to start and keep
306 enough Apache servers available to provide quick responses to clients without
307 running out of memory. The following settings are a good starting point for a
308 site that exposes the default Evergreen catalogue to the web:
310 .`/etc/apache2/mods-available/mpm_prefork.conf`
312 ------------------------------------------------------------------------------
313 <IfModule mpm_prefork_module>
318 MaxConnectionsPerChild 500
320 ------------------------------------------------------------------------------
322 . As the *root* user, enable the mpm_prefork module:
325 ------------------------------------------------------------------------------
328 ------------------------------------------------------------------------------
330 . As the *root* Linux account, enable the Evergreen site:
333 ------------------------------------------------------------------------------
334 a2dissite 000-default # OPTIONAL: disable the default site (the "It Works" page)
336 ------------------------------------------------------------------------------
338 . As the *root* Linux account, enable Apache to write
339 to the lock directory; this is currently necessary because Apache
340 is running as the `opensrf` user:
343 ------------------------------------------------------------------------------
344 chown opensrf /var/lock/apache2
345 ------------------------------------------------------------------------------
347 Learn more about additional Apache options in the following sections:
349 * xref:admin:apache_rewrite_tricks.adoc#apache_rewrite_tricks[Apache Rewrite Tricks]
350 * xref:admin:apache_access_handler.adoc#apache_access_handler_perl_module[Apache Access Handler Perl Module]
352 == Configure OpenSRF for the Evergreen application ==
354 There are a number of example OpenSRF configuration files in `/openils/conf/`
355 that you can use as a template for your Evergreen installation. Issue the
356 following commands as the *opensrf* Linux account:
359 ------------------------------------------------------------------------------
360 cp -b /openils/conf/opensrf_core.xml.example /openils/conf/opensrf_core.xml
361 cp -b /openils/conf/opensrf.xml.example /openils/conf/opensrf.xml
362 ------------------------------------------------------------------------------
364 When you installed OpenSRF, you created four Jabber users on two
365 separate domains and edited the `opensrf_core.xml` file accordingly. Please
366 refer back to the OpenSRF README and, as the *opensrf* Linux account, edit the
367 Evergreen version of the `opensrf_core.xml` file using the same Jabber users
368 and domains as you used while installing and testing OpenSRF.
371 The `-b` flag tells the `cp` command to create a backup version of the
372 destination file. The backup version of the destination file has a tilde (`~`)
373 appended to the file name, so if you have forgotten the Jabber users and
374 domains, you can retrieve the settings from the backup version of the files.
376 `eg_db_config`, described in xref:#creating_the_evergreen_database[Creating the Evergreen database], sets the database connection information in `opensrf.xml` for you.
378 === Configure action triggers for the Evergreen application ===
379 _Action Triggers_ provide hooks for the system to perform actions when a given
380 event occurs; for example, to generate reminder or overdue notices, the
381 `checkout.due` hook is processed and events are triggered for potential actions
382 if there is no checkin time.
384 To enable the default set of hooks, issue the following command as the
385 *opensrf* Linux account:
388 ------------------------------------------------------------------------------
389 cp -b /openils/conf/action_trigger_filters.json.example /openils/conf/action_trigger_filters.json
390 ------------------------------------------------------------------------------
392 For more information about configuring and running action triggers, see
393 xref:admin:actiontriggers_process.adoc#processing_action_triggers[Notifications / Action Triggers].
395 [#creating_the_evergreen_database]
396 == Creating the Evergreen database ==
398 === Setting up the PostgreSQL server ===
400 For production use, most libraries install the PostgreSQL database server on a
401 dedicated machine. Therefore, by default, the `Makefile.install` prerequisite
402 installer does *not* install the PostgreSQL 9 database server that is required
403 by every Evergreen system. You can install the packages required by Debian or
404 Ubuntu on the machine of your choice using the following commands as the
405 *root* Linux account:
407 . Installing PostgreSQL server packages
409 Each OS build target provides the postgres server installation packages
410 required for each operating system. To install Postgres server packages,
411 use the make target 'postgres-server-<OSTYPE>'. Choose the most appropriate
412 command below based on your operating system. This will install PostgreSQL 9.6,
413 the minimum supported version.
416 ------------------------------------------------------------------------------
417 make -f Open-ILS/src/extras/Makefile.install postgres-server-debian-buster
418 make -f Open-ILS/src/extras/Makefile.install postgres-server-debian-stretch
419 make -f Open-ILS/src/extras/Makefile.install postgres-server-debian-jessie
420 make -f Open-ILS/src/extras/Makefile.install postgres-server-ubuntu-xenial
421 make -f Open-ILS/src/extras/Makefile.install postgres-server-ubuntu-bionic
422 ------------------------------------------------------------------------------
424 To install PostgreSQL version 10, use the following command for your operating
428 ------------------------------------------------------------------------------
429 make -f Open-ILS/src/extras/Makefile.install postgres-server-debian-buster-10
430 make -f Open-ILS/src/extras/Makefile.install postgres-server-debian-stretch-10
431 make -f Open-ILS/src/extras/Makefile.install postgres-server-debian-jessie-10
432 make -f Open-ILS/src/extras/Makefile.install postgres-server-ubuntu-xenial-10
433 make -f Open-ILS/src/extras/Makefile.install postgres-server-ubuntu-bionic-10
434 ------------------------------------------------------------------------------
436 For a standalone PostgreSQL server, install the following Perl modules for your
437 distribution as the *root* Linux account:
440 No extra modules required for these distributions.
442 You need to create a PostgreSQL superuser to create and access the database.
443 Issue the following command as the *postgres* Linux account to create a new
444 PostgreSQL superuser named `evergreen`. When prompted, enter the new user's
448 ------------------------------------------------------------------------------
449 createuser -s -P evergreen
450 ------------------------------------------------------------------------------
452 .Enabling connections to the PostgreSQL database
454 Your PostgreSQL database may be configured by default to prevent connections,
455 for example, it might reject attempts to connect via TCP/IP or from other
456 servers. To enable TCP/IP connections from localhost, check your `pg_hba.conf`
457 file, found in the `/etc/postgresql/` directory on Debian and Ubuntu.
458 A simple way to enable TCP/IP
459 connections from localhost to all databases with password authentication, which
460 would be suitable for a test install of Evergreen on a single server, is to
461 ensure the file contains the following entries _before_ any "host ... ident"
464 ------------------------------------------------------------------------------
465 host all all ::1/128 md5
466 host all all 127.0.0.1/32 md5
467 ------------------------------------------------------------------------------
469 When you change the `pg_hba.conf` file, you will need to reload PostgreSQL to
470 make the changes take effect. For more information on configuring connectivity
472 http://www.postgresql.org/docs/devel/static/auth-pg-hba-conf.html
474 === Creating the Evergreen database and schema ===
476 Once you have created the *evergreen* PostgreSQL account, you also need to
477 create the database and schema, and configure your configuration files to point
478 at the database server. Issue the following command as the *root* Linux account
479 from inside the Evergreen source directory, replacing <user>, <password>,
480 <hostname>, <port>, and <dbname> with the appropriate values for your
481 PostgreSQL database (where <user> and <password> are for the *evergreen*
482 PostgreSQL account you just created), and replace <admin-user> and <admin-pass>
483 with the values you want for the *egadmin* Evergreen administrator account:
486 ------------------------------------------------------------------------------
487 perl Open-ILS/src/support-scripts/eg_db_config --update-config \
488 --service all --create-database --create-schema --create-offline \
489 --user <user> --password <password> --hostname <hostname> --port <port> \
490 --database <dbname> --admin-user <admin-user> --admin-pass <admin-pass>
491 ------------------------------------------------------------------------------
493 This creates the database and schema and configures all of the services in
494 your `/openils/conf/opensrf.xml` configuration file to point to that database.
495 It also creates the configuration files required by the Evergreen `cgi-bin`
496 administration scripts, and sets the user name and password for the *egadmin*
497 Evergreen administrator account to your requested values.
499 You can get a complete set of options for `eg_db_config` by passing the
502 === Loading sample data ===
504 If you add the `--load-all-sample` parameter to the `eg_db_config` command,
505 a set of authority and bibliographic records, call numbers, copies, staff
506 and regular users, and transactions will be loaded into your target
507 database. This sample dataset is commonly referred to as the _concerto_
508 sample data, and can be useful for testing out Evergreen functionality and
509 for creating problem reports that developers can easily recreate with their
510 own copy of the _concerto_ sample data.
512 === Creating the database on a remote server ===
514 In a production instance of Evergreen, your PostgreSQL server should be
515 installed on a dedicated server.
517 ==== PostgreSQL 9.6 and later ====
519 To create the database instance on a remote database server running PostgreSQL
520 9.6 or later, simply use the `--create-database` flag on `eg_db_config`.
522 == Starting Evergreen ==
524 1. As the *root* Linux account, start the `memcached` and `ejabberd` services
525 (if they aren't already running):
528 ------------------------------------------------------------------------------
529 /etc/init.d/ejabberd start
530 /etc/init.d/memcached start
531 ------------------------------------------------------------------------------
533 2. As the *opensrf* Linux account, start Evergreen. The `-l` flag in the
534 following command is only necessary if you want to force Evergreen to treat the
535 hostname as `localhost`; if you configured `opensrf.xml` using the real
536 hostname of your machine as returned by `perl -ENet::Domain 'print
537 Net::Domain::hostfqdn() . "\n";'`, you should not use the `-l` flag.
540 ------------------------------------------------------------------------------
541 osrf_control -l --start-all
542 ------------------------------------------------------------------------------
544 ** If you receive the error message `bash: osrf_control: command not found`,
545 then your environment variable `PATH` does not include the `/openils/bin`
546 directory; this should have been set in the *opensrf* Linux account's
547 `.bashrc` configuration file. To manually set the `PATH` variable, edit the
548 configuration file `~/.bashrc` as the *opensrf* Linux account and add the
552 ------------------------------------------------------------------------------
553 export PATH=$PATH:/openils/bin
554 ------------------------------------------------------------------------------
556 3. As the *opensrf* Linux account, generate the Web files needed by the web staff
557 client and catalogue and update the organization unit proximity (you need to do
558 this the first time you start Evergreen, and after that each time you change the library org unit configuration.
562 ------------------------------------------------------------------------------
564 ------------------------------------------------------------------------------
566 4. As the *root* Linux account, restart the Apache Web server:
569 ------------------------------------------------------------------------------
570 /etc/init.d/apache2 restart
571 ------------------------------------------------------------------------------
573 If the Apache Web server was running when you started the OpenSRF services, you
574 might not be able to successfully log in to the OPAC or web staff client until the
575 Apache Web server is restarted.
577 == Testing connections to Evergreen ==
579 Once you have installed and started Evergreen, test your connection to
580 Evergreen via `srfsh`. As the *opensrf* Linux account, issue the following
581 commands to start `srfsh` and try to log onto the Evergreen server using the
582 *egadmin* Evergreen administrator user name and password that you set using the
583 `eg_db_config` command:
586 ------------------------------------------------------------------------------
588 srfsh% login <admin-user> <admin-pass>
589 ------------------------------------------------------------------------------
591 You should see a result like:
593 Received Data: "250bf1518c7527a03249858687714376"
