CageFS works with any PostgreSQL version installed from CloudLinux or CentOS repositories. PostgreSQL packages fo CloudLinux 7 come from upstream (CentOS) unmodified. PostgreSQL’s socket is located in /var/run/postgresql directory. This directory is mounted to CageFS by default (in cagefs-5.5-6.34 or later).
When PostgreSQL has been installed after CageFS install, please add line:
tо /etc/cagefs/cagefs.mp file and then execute:
The steps above are enough to configure CageFS to work with PostgreSQL.
CageFS provides separate /tmp directory for each end user. Yet, PostgreSQL keeps its Unix domain socket inside server's main /tmp directory. In addition to that -- the location is hard coded inside PostgreSQL libraries.
To resolve the issue, CloudLinux provides version of PostgreSQL with modified start up script that can store PostgreSQL's socket in /var/run/postgres. The script automatically creates link from /tmp to that socket to prevent PostgreSQL dependent applications from breaking.
In addition to that, CageFS knows how to correctly link this socket inside end user's /tmp directory.
To enable PostgreSQL support in CageFS:
|1.||Make sure you have updated to latest version of PostgreSQL.|
|2.||Edit file /etc/sysconfig/postgres, and uncomment SOCK_DIR line.|
3. Update CageFS configuration by running:
4. Restart PostgreSQL by running:
If you are using cPanel, you would also need to modify file: /etc/cron.daily/tmpwatch
And update line:
to prevent symlink from being removed.
