Install OpenACS distribution

Created by OpenACS community, last modified by Gustaf Neumann 11 Oct 2017, at 08:42 AM

You should have an OpenACS distribution downloaded and available at /var/lib/aolserver/$OPENACS_SERVICE_NAME, otherwise en:Get_the_Code.

Option 1: Use an automated script

A bash script is available to automate all of the steps for the rest of this section. It requires tclwebtest. The automated script can greatly accelerate the install process, but is very sensitive to the install environment. We recommend that you run the automated install and, if it does not work the first time, consider switching to a manual installation.

Get the install script from CVS. It is located within the main cvs tree, at /etc/install. Use anonymous CVS checkout to get that directory in the home directory of the service's dedicated user. We put it there so that it is not overwritten when we do the main CVS checkout to the target location.

[root root]# su - $OPENACS_SERVICE_NAME
[$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ cvs -d :pserver:anonymous@cvs.openacs.org:/cvsroot co -d install openacs-4/etc/install
cvs server: Updating install
U install/README
U install/TODO
  ... many lines omitted ...
U install/tcl/twt-procs.tcl
U install/tcl/user-procs.tcl
[$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ cd install
[$OPENACS_SERVICE_NAME install]$ emacs install.tcl

Edit the installation configuration file, /home/$OPENACS_SERVICE_NAME/install/install.tcl and update the site-specific values, such as the new service's IP address and name, which will be written into the new service's config.tcl file. If your system is different from the one described in the previous sections, check the file paths as well. Set do_checkout=yes to create a new OpenACS site directly from a CVS checkout, or =no if you have a fully configured site and just want to rebuild it (drop and recreate the database and repeat the installation). If you have followed a stock installation, the default configuration will work without changes and will install an OpenACS site at 127.0.0.1:8000.

Run the install script install.sh as root:

[$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ exit 
[root root]# sh /home/$OPENACS_SERVICE_NAME/install/install.sh
/home/$OPENACS_SERVICE_NAME/install/install.sh: Starting installation with config_file

If there are no errors, you can browse to the "Welcome" page of your server. Be sure to visit en:docs-admin for administration help and en:docs-dev-tutorial for tutorials.

Option 2: Install available distribution

Secure the directory so that only the owner can access it. Check the permissions by listing the directory.

[root root]# su - $OPENACS_SERVICE_NAME
[$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ cd /var/lib/aolserver
[$OPENACS_SERVICE_NAME aolserver]$ tar xzf /var/tmp/openacs-5.2.0d1.tgz
[$OPENACS_SERVICE_NAME aolserver]$ mv openacs-5.2.0d1 $OPENACS_SERVICE_NAME
[$OPENACS_SERVICE_NAME aolserver]$ chmod -R 775 $OPENACS_SERVICE_NAME
[$OPENACS_SERVICE_NAME aolserver]$ chown -R $OPENACS_SERVICE_NAME.$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME

drwx------    7 $OPENACS_SERVICE_NAME web          1024 Jan  6 14:36 $OPENACS_SERVICE_NAME
[$OPENACS_SERVICE_NAME aolserver]$ exit
logout
[root root]#
su - $OPENACS_SERVICE_NAME
cd /var/lib/aolserver
tar xzf /var/tmp/openacs-5.2.0d1.tgz
mv openacs-5.2.0d1 $OPENACS_SERVICE_NAME
chmod -R 755 $OPENACS_SERVICE_NAME
chown -R $OPENACS_SERVICE_NAME.$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME
exit

Prepare the database

Prepare Oracle for OpenACS. If you won't be using Oracle, skip to Prepare PostgreSQL for an OpenACS Service

You should be sure that your user account (e.g. $OPENACS_SERVICE_NAME) is in the dba group.

1. Verify membership by typing groups when you login:

   [$OPENACS_SERVICE_NAME ~]$ groups
   dba web

   If you do not see these groups, take the following action:

   [$OPENACS_SERVICE_NAME ~]$ su -
   Password: ************
   [root ~]# adduser $OPENACS_SERVICE_NAME dba

   If you get an error about an undefined group, then add that group manually:

   [root ~]# groupadd dba
   [root ~]# groupadd web

   Make sure to logout as root when you are finished with this step and log back in as your regular user.

2. Connect to Oracle using svrmgrl and login:

   [$OPENACS_SERVICE_NAME ~]$ svrmgrl
   SVRMGR> connect internal
   Connected.

    

3. Determine where the system tablespaces are stored:

   SVRMGR> select file_name from dba_data_files;

   Example results:

   /ora8/m01/app/oracle/oradata/ora8/system01.dbf
   /ora8/m01/app/oracle/oradata/ora8/tools01.dbf
   /ora8/m01/app/oracle/oradata/ora8/rbs01.dbf
   /ora8/m01/app/oracle/oradata/ora8/temp01.dbf
   /ora8/m01/app/oracle/oradata/ora8/users01.dbf
   /ora8/m01/app/oracle/oradata/ora8/indx01.dbf
   /ora8/m01/app/oracle/oradata/ora8/drsys01.dbf

    

4. Using the above output, you should determine where to store your tablespace. As a general rule, you'll want to store your tablespace on a mount point under the /ora8 directory that is separate from the Oracle system data files. By default, the Oracle system is on m01, so we will use m02. This enables your Oracle system and database files to be on separate disks for optimized performance. For more information on such a configuration, see Chapter 12 of Philip's book. For this example, we'll use /ora8/m02/oradata/ora8/.

5. Create the directory for the datafile; to do this, exit from svrmgrl and login as root for this step:

   SVRMGR> exit
   [$OPENACS_SERVICE_NAME ~]$ su -
   Password: ************
   [root ~]# mkdir -p /ora8/m02/oradata/ora8/
   [root ~]# chown $OPENACS_SERVICE_NAME:web /ora8/m02/oradata/ora8
   [root ~]# chmod 775 /ora8/m02/oradata/ora8
   [root ~]# exit
   [$OPENACS_SERVICE_NAME ~]$

6. Create a tablespace for the service. It is important that the tablespace can autoextend. This allows the tablespace's storage capacity to grow as the size of the data grows. We set the pctincrease to be a very low value so that our extents won't grow geometrically. We do not set it to 0 at the tablespace level because this would affect Oracle's ability to automatically coalesce free space in the tablespace.

   [$OPENACS_SERVICE_NAME ~]$ svrmgrl
   SVRMGR> connect internal;
   SVRMGR> create tablespace $OPENACS_SERVICE_NAME
         datafile '/ora8/m02/oradata/ora8/$OPENACS_SERVICE_NAME01.dbf' 
         size 50M 
         autoextend on 
         next 10M
         maxsize 300M
         extent management local
         uniform size 32K;

7. Create a database user for this service. Give the user access to the tablespace and rights to connect. We'll use $OPENACS_SERVICE_NAMEpassword as our password.

   Write down what you specify as service_name (i.e. $OPENACS_SERVICE_NAME) and database_password (i.e. $OPENACS_SERVICE_NAMEpassword). You will need this information for configuring exports and AOLserver.

   SVRMGR> create user $OPENACS_SERVICE_NAME identified by $OPENACS_SERVICE_NAMEpassword default tablespace $OPENACS_SERVICE_NAME
       temporary tablespace temp quota unlimited on $OPENACS_SERVICE_NAME;
   SVRMGR> grant connect, resource, ctxapp, javasyspriv, query rewrite, create view, create synonym to $OPENACS_SERVICE_NAME;
   SVRMGR> revoke unlimited tablespace from $OPENACS_SERVICE_NAME;
   SVRMGR> alter user $OPENACS_SERVICE_NAME quota unlimited on $OPENACS_SERVICE_NAME;
   SVRMGR> exit;

   Your table space is now ready. In case you are trying to delete a previous OpenACS installation, consult these commands in the section called “Deleting a tablespace” below.

8. Make sure that you can login to Oracle using your service_name account:

   [$OPENACS_SERVICE_NAME ~]$ sqlplus $OPENACS_SERVICE_NAME/$OPENACS_SERVICE_NAMEpassword
   SQL> select sysdate from dual;
   SYSDATE
   ----------
   2001-12-20
   SQL> exit;

   You should see today's date in a format 'YYYY-MM-DD.' If you can't login, try redoing step 1 again. If the date is in the wrong format, make sure you followed the steps outlined in the section called “Troubleshooting Oracle Dates”

Prepare PostgreSQL for an OpenACS Service.

• PostgreSQL:

  Create a user in the database matching the service name. With default PostgreSQL authentication, a system user connecting locally automatically authenticates as the postgres user of the same name, if one exists. We currently use postgres "super-users" for everything, which means that anyone with access to any of the openacs system accounts on a machine has full access to all postgresql databases on that machine.

  [root root]# su - postgres
  [postgres pgsql]$ createuser -a -d $OPENACS_SERVICE_NAME
  CREATE USER
  [postgres pgsql]$ exit
  logout
  [root root]#

• Create a database with the same name as our service name, $OPENACS_SERVICE_NAME.

  [root root]# su - $OPENACS_SERVICE_NAME
  [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ createdb -E UNICODE $OPENACS_SERVICE_NAME
  CREATE DATABASE

• Automate daily database Vacuuming. This is a process which cleans out discarded data from the database. A quick way to automate vacuuming is to edit the cron file for the database user. Recommended: VACUUM ANALYZE every hour and VACUUM FULL ANALYZE every day.

  [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ export EDITOR=emacs;crontab -e

  Add these lines to the file. The vacuum command cleans up temporary structures within a PostGreSQL database, and can improve performance. We vacuum gently every hour and completely every day. The numbers and stars at the beginning are cron columns that specify when the program should be run - in this case, whenever the minute is 0 and the hour is 1, i.e., 1:00 am every day, and every (*) day of month, month, and day of week. Type man 5 crontab for more information.

  0 1-23 * * * /usr/local/pgsql/bin/vacuumdb --analyze $OPENACS_SERVICE_NAME
  0 0 * * * /usr/local/pgsql/bin/vacuumdb --full --analyze $OPENACS_SERVICE_NAME

  Depending on your distribution, you may receive email when the crontab items are executed. If you don't want to receive email for those crontab items, you can add > /dev/null 2>&1 to the end of each crontab line

  At this point the database should be ready for installing OpenACS.

Configure an AOLserver Service for OpenACS.

1. The AOLserver architecture lets you run an arbitrary number of virtual servers. A virtual server is an HTTP service running on a specific port, e.g. port 80. In order for OpenACS to work, you need to configure a virtual server. The Reference Platform uses a configuration file included in the OpenACS tarball, /var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/config.tcl. Open it in an editor to adjust the parameters.

   [root root]# su - $OPENACS_SERVICE_NAME
   [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ cd /var/lib/aolserver/$OPENACS_SERVICE_NAME/etc
   [$OPENACS_SERVICE_NAME etc]$ emacs config.tcl
   

   You can continue without changing any values in the file. However, if you don't change address to match the computer's ip address, you won't be able to browse to your server from other machines. See en:aolserver-admin for an explanation of some other values you might want to change in the config.tcl file.

Verify AOLserver startup.

1. Kill any current running AOLserver processes and start a new one. The recommended way to start an AOLserver process is by running the included script, /var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/daemontools/run. If you are not using the default file paths and names, you will need to edit run.

   If you want to use port 80, there are complications. AOLserver must be root to use system ports such as 80, but refuses to run as root for security reasons. So, we call the run script as root and specify a non-root user ID and Group ID which AOLserver will switch to after claiming the port. To do so, find the UID and GID of the $OPENACS_SERVICE_NAME user via grep $OPENACS_SERVICE_NAME /etc/passwd and then put those numbers into the command line via -u 501 -g 502. In AOLserver 4, you must also send a -b flag. Do this by editing the run file as indicated in the comments.

   If you are root then killall will affect all OpenACS services on the machine, so if there's more than one you'll have to do ps -auxw | grep nsd and selectively kill by job number.

   [$OPENACS_SERVICE_NAME etc]$ killall nsd
   nsd: no process killed
   [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ /usr/local/aolserver/bin/nsd-postgres -t /var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/config.tcl
   [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ [08/Mar/2003:18:13:29][32131.8192][-main-] Notice: nsd.tcl: starting to read config file...
   [08/Mar/2003:18:13:29][32131.8192][-main-] Notice: nsd.tcl: finished reading config file.

2. Attempt to connect to the service from a web browser. You should specify a URL like: http://yourserver.test:8000

   You should see a page that looks like this, otherwise check the en:aolserver-admin Troobleshooting secton.

Configure a Service with the OpenACS Installer. Now that you've got AOLserver up and running, let's install OpenACS 5.2.0d1.

• You should see a page from the webserver titled OpenACS Installation: Welcome. You will be warned if your version of the database driver is out of date, if AOLserver cannot connect to the database, if any modules are missing or out-of-date, or if there are any problems with filesystem permissions on the server side. But if everything is fine, you can click Next to proceed to load the OpenACS Kernel data model.

• The next page shows the results of loading the OpenACS Kernel data model - be prepared to wait a few minutes as it works. You should see a string of output messages from the database as the datamodel is created. You'll see the line:

  Loading package .info files ... this will take a few minutes

  This will really take a few minutes. Have faith! Finally, another Next button will appear at the bottom - click it.

• The following page shows the results of loading the core package data models. You should see positive results for each of the previously selected packages, but watch out for any errors. Eventually, the page will display "Generating secret tokens" and then "Done"- click Next.

• You should see a page, "OpenACS Installation: Create Administrator" with form fields to define the OpenACS site administrator. Fill out the fields as appropriate, and click Create User.

• You should see a page, "OpenACS Installation: Set System Information" allowing you to name your service. Fill out the fields as appropriate, and click Set System Information

• You'll see the final Installer page, "OpenACS Installation: Complete." It will tell you that the server is being restarted; note that unless you already set up a way for AOLserver to restart itself (ie. inittab or daemontools), you'll need to manually restart your service.

  [$OPENACS_SERVICE_NAME $OPENACS_SERVICE_NAME]$ /usr/local/aolserver/bin/nsd-postgres -t /var/lib/aolserver/$OPENACS_SERVICE_NAME/etc/config.tcl

• Give the server a few minutes to start up. Then reload the final page above. You should see the front page, with an area to login near the upper right. Congratulations, OpenACS <version> is now up and running!

for everyone

Created by OpenACS community, last modified by Benjamin Brink 22 Jul 2017, at 11:49 PM

OpenACS for everyone

OpenACS (Open Architecture Community System) is:

• an advanced toolkit for building scalable, community-oriented web applications.
• a robust, scalable framework (see: en:openacs-system) for building dynamic content driven sites and enterprise-level web applications.
• a collection of pre-built applications and services that you can build on to create a custom web-site or application.
• derived from the ArsDigita Community System (ACS). ArsDigita (now part of Red Hat, Inc.) kindly made their work available under the GPL, making all of this possible.

Through a modular architecture, OpenACS has packages for user/groups management, content management, e-commerce, news, FAQs, calendar, forums, bug tracking, wiki (XoWiki), full-text searching etc. See OpenACS repository.

Strengths

• Ready "out of the box" for common features of collaborative web sites. See en:feature-summary
• Proven Architecture. Components of the OpenACS (see en:openacs-system) are proving themselves in the most demanding of applications
• Designed for scalability See: http://en.wikipedia.org/wiki/Scalability#Design_for_scalability
• Proven in the field. OpenACS is working well, deployed at sites that have upwards of 40K users (See e.g. AIESEC at OpenACS sites)
• Responsive Community See: en:community-culture
• Commercial Support In addition to Commercial Support, there are many independent consultants available for hire. This collection of commercial providers work together to maintain OpenACS in addition to competing for clients. Sometimes vendors work together for the same client. Most importantly, no client is ever left without support, even if his or her original provider goes out of business.
• Documentation is continually evolving and improving. (See: en:Documentation_Project)
• Institutional commitment. Including MIT Sloan School of Management which has initiated and led the development of .LRN, an open-source courseware system built on OpenACS. (See Institutions supporting .LRN)
• Extensible See: http://en.wikipedia.org/wiki/Extensible

Use the OpenACS fourms to contact the OpenACS community. We welcome your feedback and can help with your OpenACS endeavors. Commercial support is also available.
