Installing Memcache on CentOS


1

  • Check to make sure that you are running a recent version of CentOS by entering "cat /etc/redhat-release." As of June 2011, the most recent version of CentOS is version 5.6.

    Download and setup your system and Memcache to be installed on your server by entering the following commands:
    "cd /user/local/src"
    "curl -O http://memcached.googlecode.com/files/memcached-1.4.5.tar.gz"
    "tar xzvf memcached-1.4.5.tar.gz"
    "cd memcached-1.4.5"
    "LDFLAGS='-W1, --rpath /usr/local/lib' ./configure --prefix=/usr/local"
    These commands move the src directory on your system, download Memcache and set the flags that are required to make Memcache work properly on your system.

    Run a simple make install to complete the Memcache installation; the code for this is "make && make install." Please note that you will need root privileges to run this command successfully; this is done in CentOS using the "su" command and entering your root password. Be sure that when the process is completed you "su" back your regular user.

    Verify that Memcache is installed properly on your system using the following command: "ps auz | grep memcached." If there are no errors printed in your terminal, then everything is fine with your installation. You can stop Memcache with "pkill memcached."
