This is a simple guide to get Memcached and the Memcache/Memcached module(s) for PHP installed on Arch Linux.
One of the things I love about Arch is it’s package manager. It’s always up-to-date and has a lot of packages including all the packages we need to get Memcached running. To install memcache, simply run
Memcached is now installed! Let’s get it running.
Let’s go over this command:
- d: tells Memcached to run as a daemon
- m: the memory (Memcached uses actual memory and not disk memory)
- l: where to listen, here would only listen for local requests, if you want to allow other computers to access Memcached, specify the external IP
- p: the port, default 11211
- u: the user to run as
To make sure Memcached is running.
To make sure that Memcached always starts on startup, add the command to /etc/rc.local.
Now that we have Memcached installed, we need to install the Memcache/Memcached modules for PHP installed. If you have PECL installed and configured, you can do it that way, or use pacman.
Both of these commands will create a config file for the module in /etc/php/conf.d/. To enable the module you need to edit the config file (I used memcached, so edit /etc/php/conf.d/memcached.ini) and uncomment the line in there.
Finally run /etc/rc.d/httpd restart and there you go, you can start using Memcached in PHP.
