Installing OpenACS on Redhat

Redhat publishes 2 versions of their OS, Fedora (FC) and Redhat Enterprise...

The quicksheet versions:

You should know what you're doing when you use them.

Should you decide to Install OpenACS from source using general en:openacs-system-install instructions, refer to these notes for changes.

Some of these notes below are probably outdated by now, but might still give some useful hints for certain installations.

Notes for Installing Postgresql en:postgresql-install

If you install PostgreSQL 7.3.2 from the Red Hat 9 RPM, you can skip a few steps. These shell commands add some links for compatibility with the directories from a source-based install; start the service; create a new group for web service users, and modify the postgres user's environment (more information):

[root root]# ln -s /usr/lib/pgsql/ /var/lib/pgsql/lib
[root root]# ln -s /var/lib/pgsql /usr/local/pgsql
[root root]# ln -s /etc/init.d/postgresql /etc/init.d/postgres
[root root]# ln -s /usr/bin /usr/local/pgsql/bin
[root root]# service postgresql start
Initializing database:
                                                           [  OK  ]
Starting postgresql service:                               [  OK  ]
[root root]# echo "export LD_LIBRARY_PATH=/usr/local/pgsql/lib" >> ~postgres/.bash_profile
[root root]# echo "export PATH=$PATH:/usr/local/pgsql/bin" >> ~postgres/.bash_profile
[root root]# groupadd web
[root root]# su - postgres
-bash-2.05b$

ln -s /usr/lib/pgsql/ /var/lib/pgsql/lib
ln -s /var/lib/pgsql /usr/local/pgsql
ln -s /usr/bin /usr/local/pgsql/bin
service postgresql start
echo "export LD_LIBRARY_PATH=/usr/local/pgsql/lib" >> ~postgres/.bash_profile
echo "export PATH=$PATH:/usr/local/pgsql/bin" >> ~postgres/.bash_profile
groupadd web
su - postgres

... and then skip to the section in en:postgresql-install that deals with installing plpgsql.

Set PostgreSQL to start on boot

Red Hat RPM:

The init script is already installed; just turn it on for the appropriate run levels.

[root root]# chkconfig --level 345 postgresql on
[root root]# 

Red Hat from source:

[root src]# cp /var/tmp/openacs-5.2.0d1/packages/acs-core-docs/www/files/postgresql.txt /etc/init.d/postgresql
[root src]# chown root.root /etc/rc.d/init.d/postgresql
[root src]# chmod 755 /etc/rc.d/init.d/postgresql
[root src]# 
cp /var/tmp/openacs-5.2.0d1/packages/acs-core-docs/www/files/postgresql.txt /etc/init.d/postgresql
chown root.root /etc/rc.d/init.d/postgresql
chmod 755 /etc/rc.d/init.d/postgresql

Test the script.

[root root]# service postgresql stop
Stopping PostgreSQL: ok
[root root]# 

If PostgreSQL successfully stopped, then use the following command to make sure that the script is run appropriately at boot and shutdown. And turn it back on because we'll use it later.

[root root]# chkconfig --add postgresql
[root root]# chkconfig --level 345 postgresql on
[root root]# chkconfig --list postgresql
postgresql      0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root root]# service postgresql start
Starting PostgreSQL: ok
[root root]#
chkconfig --add postgresql
chkconfig --level 345 postgresql on
chkconfig --list postgresql
service postgresql start

Red Hat defaults to starting services on 3-5. So, on Red Hat, PostgreSQL won't start on runlevel 2 unless you alter the above commands a little. This usually isn't a problem as Red Hat defaults to runlevel 3)
