Installing Zend Server on Centos to run Magento

Installed Zend Server CE on one of my servers today.

Installing Zend Server CE via yum on Centos

To install via YUM, you can add the Zend repo as /etc/yum.repos.d/zend.repo [Zend] name=Zend CE $releasever - $basearch - Released Updates baseurl=http://repos.zend.com/rpm/ce/$basearch/ enabled=1 gpgcheck=0 [Zendce-noarch] name=Zend CE - noarch baseurl=http://repos.zend.com/rpm/ce/noarch enabled=1 gpgcheck=0

Then run yum install zend-ce

This will run a muck on your current website, it basically replaces your current php installation, replaces your mod_php with a zend. The files for the Zend Server are stored in /usr/local/zend. You will need to restart apache to take advantage of the new Zend.

Accessing the Zend Server admin interface

In a browser you just go to <yourserver>:10081, from there it will prompt you for a password, then pass you along to the Zend admin page. From there you can enable caching/optimization.

Magento

I already had Magento installed, and Zend Server messed with some settings that caused my Magento to generate an error.

Can't connect to local MySQL server through socket '/tmp/mysql.sock'

This took me a while to figure out, it went around looking at the config files for Zend /usr/local/zend/etc/conf.d/ that didn’t seem to help. The fix was specifically telling Magento what unix_socket to use for the db connection. Need to change local.xml `

  <connection>
      <host><![CDATA[localhost]]></host>
      <username><![CDATA[YOURUSERNAME]]></username>
      <password><![CDATA[YOURPASSWORD]]></password>
      <dbname><![CDATA[YOURDBNAME]]></dbname>
      <unix_socket><![CDATA[/var/lib/mysql/mysql.sock]]></unix_socket>
      <active>1</active>
  </connection>

`

I enabled both the Zend Cache and the Zend Optimizer+ and saw some decent increases in performance. Magento is a resource hog and you really need a beefy server to run it, utilizing cacheing is almost a must.
