4 Preamble: referenced user accounts
5 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
7 In subsequent sections, we will refer to a number of different accounts, as
10 * Linux user accounts:
11 ** The *user* Linux account is the account that you use to log onto the
12 Linux system as a regular user.
13 ** The *root* Linux account is an account that has system administrator
14 privileges. On Debian and Fedora you can switch to this account from
15 your *user* account by issuing the `su -` command and entering the
16 password for the *root* account when prompted. On Ubuntu you can switch
17 to this account from your *user* account using the `sudo su -` command
18 and entering the password for your *user* account when prompted.
19 ** The *opensrf* Linux account is an account that you create when installing
20 OpenSRF. You can switch to this account from the *root* account by
21 issuing the `su - opensrf` command.
22 ** The *postgres* Linux account is created automatically when you install
23 the PostgreSQL database server. You can switch to this account from the
24 *root* account by issuing the `su - postgres` command.
25 * PostgreSQL user accounts:
26 ** The *evergreen* PostgreSQL account is a superuser account that you will
27 create to connect to the PostgreSQL database server.
28 * Evergreen administrator account:
29 ** The *egadmin* Evergreen account is an administrator account for
30 Evergreen that you will use to test connectivity and configure your
33 Preamble: Getting an Evergreen official release tarball
34 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
36 To download and extract the source for the current release of Evergreen, issue
37 the following commands as the *user* Linux account:
40 ------------------------------------------------------------------------------
41 wget -c http://evergreen-ils.org/downloads/Evergreen-ILS-2.2-alpha1.tar.gz
42 tar xzf Evergreen-ILS-2.2-alpha1.tar.gz
43 ------------------------------------------------------------------------------
45 Preamble: Developer instructions
46 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
49 Skip this section if you are using an official release tarball downloaded
50 from http://evergreen-ils.org/downloads
52 Developers working directly with the source code from the Git repository,
53 rather than an official release tarball, must install some extra packages
54 and perform one step before they can proceed with the `./configure` step.
56 As the *root* Linux account, install the following packages:
62 As the *user* Linux account, issue the following command in the Evergreen
63 source directory to generate the configure script and Makefiles:
66 ------------------------------------------------------------------------------
68 ------------------------------------------------------------------------------
70 After running `make install`, developers also need to install the Dojo Toolkit
71 set of JavaScript libraries. The appropriate version of Dojo is included
72 in Evergreen release tarballs. Developers should install the Dojo 1.3.3
73 version of Dojo by issuing the following commands as the *opensrf* Linux
77 ------------------------------------------------------------------------------
78 wget http://download.dojotoolkit.org/release-1.3.3/dojo-release-1.3.3.tar.gz
79 tar -C /openils/var/web/js -xzf dojo-release-1.3.3.tar.gz
80 cp -r /openils/var/web/js/dojo-release-1.3.3/* /openils/var/web/js/dojo/.
81 ------------------------------------------------------------------------------
83 Installing prerequisites
84 ~~~~~~~~~~~~~~~~~~~~~~~~
86 Evergreen has a number of prerequisite packages that must be installed
87 before you can successfully configure, compile, and install Evergreen.
89 1. Begin by installing the most recent version of OpenSRF (2.0 or later).
90 You can download OpenSRF releases from http://evergreen-ils.org/opensrf.php
91 2. On many distributions, it is necessary to install PostgreSQL 9 from external
94 * On Debian Squeeze, open `/etc/apt/sources.list` in a text editor as the
95 *root* Linux account and add the following line:
98 ------------------------------------------------------------------------------
99 deb http://backports.debian.org/debian-backports squeeze-backports main contrib
100 ------------------------------------------------------------------------------
102 * On Ubuntu Lucid, you can use a PPA (personal package archive), which are
103 package sources hosted on Launchpad. The one most commonly used by Evergreen
104 Community members is maintained by Martin Pitt, who also maintains the
105 official PostgreSQL packages for Ubuntu. As the *root* Linux account, issue
106 the following commands to add the PPA source:
109 ------------------------------------------------------------------------------
110 apt-get install python-software-properties
111 add-apt-repository ppa:pitti/postgresql
112 ------------------------------------------------------------------------------
114 * Fedora 16 comes with PostgreSQL 9, so no additional steps are required.
116 3. On Debian and Ubuntu, run `aptitude update` as the *root* Linux account to
117 retrieve the new packages from the backports repository.
118 4. Issue the following commands as the *root* Linux account to install
119 prerequisites using the `Makefile.install` prerequisite installer,
120 substituting `debian-squeeze`, `fedora16`, `ubuntu-lucid`, `centos`, or
121 `rhel` for <osname> below:
124 ------------------------------------------------------------------------------
125 make -f Open-ILS/src/extras/Makefile.install <osname>
126 ------------------------------------------------------------------------------
129 `centos` and `rhel` are less tested than the `debian`, `fedora`,
130 and `ubuntu` options. Your patches and suggestions for improvement are
133 5. Add the libdbi-libdbd libraries to the system dynamic library path by
134 issuing the following commands as the *root* Linux account:
138 ------------------------------------------------------------------------------
139 echo "/usr/local/lib/dbd" > /etc/ld.so.conf.d/eg.conf
141 ------------------------------------------------------------------------------
145 ------------------------------------------------------------------------------
146 echo "/usr/lib64/dbd" > /etc/ld.so.conf.d/eg.conf
148 ------------------------------------------------------------------------------
150 Configuration and compilation instructions
151 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
153 For the time being, we are still installing everything in the `/openils/`
154 directory. From the Evergreen source directory, issue the following commands as
155 the *user* Linux account to configure and build Evergreen:
158 ------------------------------------------------------------------------------
159 ./configure --prefix=/openils --sysconfdir=/openils/conf
161 ------------------------------------------------------------------------------
163 Installation instructions
164 ~~~~~~~~~~~~~~~~~~~~~~~~~
166 1. Once you have configured and compiled Evergreen, issue the following
167 command as the *root* Linux account to install Evergreen, build the server
168 portion of the staff client, and copy example configuration files to
170 Change the value of the `STAFF_CLIENT_STAMP_ID` variable to match the version
171 of the staff client that you will use to connect to the Evergreen server.
174 ------------------------------------------------------------------------------
175 make STAFF_CLIENT_STAMP_ID=rel_2_2_alpha1 install
176 ------------------------------------------------------------------------------
178 2. The server portion of the staff client expects `http://hostname/xul/server`
179 to resolve. Issue the following commands as the *root* Linux account to
180 create a symbolic link pointing to the `server` subdirectory of the server
181 portion of the staff client that we just built using the staff client ID
185 ------------------------------------------------------------------------------
186 cd /openils/var/web/xul
187 ln -sf rel_name/server server
188 ------------------------------------------------------------------------------
190 Change ownership of the Evergreen files
191 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
193 All files in the `/openils/` directory and subdirectories must be owned by the
194 `opensrf` user. Issue the following command as the *root* Linux account to
195 change the ownership on the files:
198 ------------------------------------------------------------------------------
199 chown -R opensrf:opensrf /openils
200 ------------------------------------------------------------------------------
202 Configure the Apache Web server
203 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
205 1. Use the example configuration files in `Open-ILS/examples/apache/` to
206 configure your Web server for the Evergreen catalog, staff client, Web
207 services, and administration interfaces. Issue the following commands as the
208 *root* Linux account:
212 ------------------------------------------------------------------------------
213 cp Open-ILS/examples/apache/eg.conf /etc/apache2/sites-available/
214 cp Open-ILS/examples/apache/eg_vhost.conf /etc/apache2/
215 cp Open-ILS/examples/apache/startup.pl /etc/apache2/
217 mkdir /etc/apache2/ssl
219 ------------------------------------------------------------------------------
223 ------------------------------------------------------------------------------
224 cp Open-ILS/examples/apache/eg.conf /etc/httpd/sites-available/
225 cp Open-ILS/examples/apache/eg_vhost.conf /etc/httpd/
226 cp Open-ILS/examples/apache/startup.pl /etc/httpd/
230 ------------------------------------------------------------------------------
232 2. The `openssl` command cuts a new SSL key for your Apache server. For a
233 production server, you should purchase a signed SSL certificate, but you can
234 just use a self-signed certificate and accept the warnings in the staff client
235 and browser during testing and development. Create an SSL key for the Apache
236 server by issuing the following command as the *root* Linux account:
239 ------------------------------------------------------------------------------
240 openssl req -new -x509 -days 365 -nodes -out server.crt -keyout server.key
241 ------------------------------------------------------------------------------
243 3. As the *root* Linux account, edit the `eg.conf` file that you copied into
245 a. Replace `Allow from 10.0.0.0/8` with `Allow from all` (to enable
246 access to the offline upload / execute interface from any workstation on
247 any network - note that you must secure this for a production instance)
248 4. Change the user for the Apache server.
249 * (Debian and Ubuntu): As the *root* Linux account, edit
250 `/etc/apache2/envvars`. Change `export APACHE_RUN_USER=www-data` to
251 `export APACHE_RUN_USER=opensrf`.
252 * (Fedora): As the *root* Linux account , edit `/etc/httpd/conf/httpd.conf`.
253 Change `User apache` to `User opensrf`.
254 5. Configure Apache with performance settings appropriate for Evergreen:
255 * (Debian and Ubuntu): As the *root* Linux account, edit
256 `/etc/apache2/apache2.conf`:
257 * (Fedora): As the *root* Linux account, edit `/etc/httpd/conf/httpd.conf`:
258 a. Change `KeepAliveTimeout` to `1`. Higher values reduce the chance of
259 a request timing out unexpectedly, but increase the risk of using up
260 all available Apache child processes.
261 b. 'Optional': Change `MaxKeepAliveRequests` to `100`
262 c. Update the prefork configuration section to suit your environment. The
263 following settings apply to a busy system:
266 ------------------------------------------------------------------------------
267 <IfModule mpm_prefork_module>
272 MaxRequestsPerChild 10000
274 ------------------------------------------------------------------------------
276 6. (Debian and Ubuntu): As the *root* Linux account, enable the Evergreen site:
279 ------------------------------------------------------------------------------
280 a2dissite default # OPTIONAL: disable the default site (the "It Works" page)
282 ------------------------------------------------------------------------------
284 Configure OpenSRF for the Evergreen application
285 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
286 There are a number of example OpenSRF configuration files in `/openils/conf/`
287 that you can use as a template for your Evergreen installation. Issue the
288 following commands as the *opensrf* Linux account:
291 ------------------------------------------------------------------------------
292 cp -b /openils/conf/opensrf_core.xml.example /openils/conf/opensrf_core.xml
293 cp -b /openils/conf/opensrf.xml.example /openils/conf/opensrf.xml
294 ------------------------------------------------------------------------------
296 When you installed OpenSRF, you created four Jabber users on two
297 separate domains and edited the `opensrf_core.xml` file accordingly. Please
298 refer back to the OpenSRF README and, as the *opensrf* Linux account, edit the
299 Evergreen version of the `opensrf_core.xml` file using the same Jabber users
300 and domains as you used while installing and testing OpenSRF.
303 The `-b` flag tells the `cp` command to create a backup version of the
304 destination file. The backup version of the destination file has a tilde (`~`)
305 appended to the file name, so if you have forgotten the Jabber users and
306 domains, you can retrieve the settings from the backup version of the files.
308 `eg_db_config.pl`, described in the following section, sets the database
309 connection information in `opensrf.xml` for you.
311 Creating the Evergreen database
312 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
314 By default, the `Makefile.install` prerequisite installer does not install
315 the PostgreSQL 9 database server required by every Evergreen system;
316 for production use, most libraries install the PostgreSQL database server on a
317 dedicated machine. You can install the packages required by Debian or Ubuntu
318 on the machine of your choice using the following commands as the *root*
321 .(Debian / Ubuntu) Installing PostgreSQL 9.1 server packages
323 ------------------------------------------------------------------------------
324 make -f Open-ILS/src/extras/Makefile.install install_pgsql_server_debs_91
325 ------------------------------------------------------------------------------
327 You can install the packages required by Fedora on the machine of your choice
328 using the following commands as the *root* Linux account:
330 .(Fedora 16) Installing PostgreSQL server packages
332 ------------------------------------------------------------------------------
333 make -f Open-ILS/src/extras/Makefile.install install_fedora_pgsql_server
334 ------------------------------------------------------------------------------
336 For a standalone PostgreSQL server, install the following Perl modules as the
337 *root* Linux account:
339 .(Debian / Ubuntu) Installing additional Perl modules on a standalone PostgreSQL 9 server
341 ------------------------------------------------------------------------------
342 aptitude install gcc libxml-libxml-perl libxml-libxslt-perl
345 cpan Library::CallNumber::LC
349 ------------------------------------------------------------------------------
351 .(Fedora 16) Installing additional Perl modules on a standalone PostgreSQL 9 server
353 ------------------------------------------------------------------------------
354 yum install gcc perl-XML-LibXML perl-XML-LibXSLT perl-Business-ISBN
355 cpan Library::CallNumber::LC
359 ------------------------------------------------------------------------------
361 You need to create a PostgreSQL superuser to create and access the database.
362 Issue the following command as the *postgres* Linux account to create a new
363 PostgreSQL superuser named `evergreen`. When prompted, enter the new user's
367 ------------------------------------------------------------------------------
368 createuser -s -P evergreen
369 ------------------------------------------------------------------------------
371 Once you have created the *evergreen* PostgreSQL account, you also need to
372 create the database and schema, and configure your configuration files to point
373 at the database server. Issue the following command as the *root* Linux account
374 from inside the Evergreen source directory, replacing <user>, <password>,
375 <hostname>, <port>, and <dbname> with the appropriate values for your
376 PostgreSQL database (where <user> and <password> are for the *evergreen*
377 PostgreSQL account you just created), and replace <admin-user> and <admin-pass>
378 with the values you want for the *egadmin* Evergreen administrator account:
381 ------------------------------------------------------------------------------
382 perl Open-ILS/src/support-scripts/eg_db_config.pl --update-config \
383 --service all --create-database --create-schema --create-offline \
384 --user <user> --password <password> --hostname <hostname> --port <port> \
385 --database <dbname> --admin-user <admin-user> --admin-pass <admin-pass>
386 ------------------------------------------------------------------------------
388 This creates the database and schema and configures all of the services in
389 your `/openils/conf/opensrf.xml` configuration file to point to that database.
390 It also creates the configuration files required by the Evergreen `cgi-bin`
391 administration scripts, and sets the user name and password for the *egadmin*
392 Evergreen administrator account to your requested values.
394 Creating the database on a remote server
395 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
396 In a production instance of Evergreen, your PostgreSQL server should be
397 installed on a dedicated server. For PostgreSQL 9.1 and later you should be
398 able to continue to use the --create-database flag on eg_db_config.pl, without
399 needing to install any server modules on your application machine. For
400 PostgreSQL 9.0 you can either:
402 * Install the PostgreSQL contrib modules on the machine on which you
403 are installing the Evergreen code, and use the --create-database
404 option from that machine, or
405 * Copy the `Open-ILS/src/sql/Pg/create_database.sql` script to your
406 PostgreSQL server and invoke it as the *postgres* Linux account:
409 ------------------------------------------------------------------------------
410 psql -vdb_name=<dbname> -vcontrib_dir=`pg_config --sharedir`/contrib -f create_database.sql
411 ------------------------------------------------------------------------------
413 Then you can issue the `eg_db_config.pl` command as above _without_ the
414 `--create-database` argument to create your schema and configure your
419 1. As the *root* Linux account, start the `memcached` and `ejabberd` services
420 (if they aren't already running):
423 ------------------------------------------------------------------------------
424 /etc/init.d/ejabberd start
425 /etc/init.d/memcached start
426 ------------------------------------------------------------------------------
428 2. As the *opensrf* Linux account, start Evergreen. The `-l` flag in the
429 following command is only necessary if you want to force Evergreen to treat the
430 hostname as `localhost`; if you configured `opensrf.xml` using the real
431 hostname of your machine as returned by `perl -ENet::Domain 'print
432 Net::Domain::hostfqdn() . "\n";'`, you should not use the `-l` flag.
435 ------------------------------------------------------------------------------
436 osrf_ctl.sh -l -a start_all
437 ------------------------------------------------------------------------------
439 ** If you receive the error message `bash: osrf_ctl.sh: command not found`,
440 then your environment variable `PATH` does not include the `/openils/bin`
441 directory; this should have been set in the *opensrf* Linux account's
442 `.bashrc` configuration file. To manually set the `PATH` variable, edit the
443 configuration file `~/.bashrc` as the *opensrf* Linux account and add the
447 ------------------------------------------------------------------------------
448 export PATH=$PATH:/openils/bin
449 ------------------------------------------------------------------------------
451 3. As the *opensrf* Linux account, generate the Web files needed by the staff
452 client and catalogue and update the organization unit proximity (you need to do
453 this the first time you start Evergreen, and after that each time you change
454 the library hierarchy in `config.cgi`):
457 ------------------------------------------------------------------------------
459 ------------------------------------------------------------------------------
461 4. As the *root* Linux account, restart the Apache Web server:
464 ------------------------------------------------------------------------------
465 /etc/init.d/apache2 restart
466 ------------------------------------------------------------------------------
468 If the Apache Web server was running when you started the OpenSRF services, you
469 might not be able to successfully log in to the OPAC or staff client until the
470 Apache Web server is restarted.
472 Testing connections to Evergreen
473 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
475 Once you have installed and started Evergreen, test your connection to
476 Evergreen via `srfsh`. As the *opensrf* Linux account, issue the following
477 commands to start `srfsh` and try to log onto the Evergreen server using the
478 *egadmin* Evergreen administrator user name and password that you set using the
479 `eg_db_config.pl` command:
482 ------------------------------------------------------------------------------
484 srfsh% login <admin-user> <admin-pass>
485 ------------------------------------------------------------------------------
487 You should see a result like:
489 Received Data: "250bf1518c7527a03249858687714376"
490 ------------------------------------
491 Request Completed Successfully
492 Request Time in seconds: 0.045286
493 ------------------------------------
497 "textcode":"SUCCESS",
500 "stacktrace":"oils_auth.c:304",
502 "authtoken":"e5f9827cc0f93b503a1cc66bee6bdd1a",
508 ------------------------------------
509 Request Completed Successfully
510 Request Time in seconds: 1.336568
511 ------------------------------------
513 If this does not work, it's time to do some troubleshooting.
515 * As the *opensrf* Linux acccount, run the `settings-tester.pl` script to see
516 if it finds any system configuration problems. The script is found at
517 `Open-ILS/src/support-scripts/settings-tester.pl` in the Evergreen source
519 * Follow the steps in the http://evergreen-ils.org/dokuwiki/doku.php?id=troubleshooting:checking_for_errors[troubleshooting guide].
520 * If you have faithfully followed the entire set of installation steps
521 listed here, you are probably extremely close to a working system.
