Install Memcached

Memcached caches Subversion (SVN) authentication and authorization information and serves the mod_authnz_ctf module's authentication and authorization requests thereby reducing the number of SOAP calls, which in turn results in less load on the TeamForge Application Server.

See this wiki page for more information about Memcached.
Memcached can run on the TeamForge Application Server or on a separate server. This document assumes that you install Memcached on the TeamForge Application Server.
Caching is disabled by default in TeamForge. Enable it by setting up the following site-options.conf tokens.

To set up caching with Memcached:

Install Memcached.
Configure Memcached settings.
Set up the TeamForge site options.
Recreate the TeamForge runtime environment.

Do this on the TeamForge Application Server.

Install Memcached.
- yum clean all
- yum -y install memcached
Configure the OPTIONS key in the Memcached configuration file (/etc/sysconfig/memcached) and start Memcached.
1. The OPTIONS key in the memcached configuration file is used to set additional options during Memcached startup. Add the -l <ip-addr> flag to have Memcached listen to <ip_addr>. This is an important option to consider as there is no other way to secure the installation. Binding to an internal or firewalled network interface is recommended.
  - vi /etc/sysconfig/memcached
  Important: Remove the -l flag from the OPTIONS key to have Memcached listen to the server's default IP address or host name, including the 'localhost'.
2. Start Memcached.
  - Start Memcached during system boot up: sudo systemctl enable memcached
  - Start Memcached normally: sudo systemctl start memcached
Set up the following tokens in the TeamForge site-options.conf file.
See:
Recreate the TeamForge runtime environment.
- cd /opt/collabnet/teamforge-installer/16.3
- ./install.sh -r -n -V -d /opt/collabnet/teamforge
