You have a little problem?

This is The solution (thanks to @DwebConsulting).

1. sudo service mysql stop
2. sudo cp /etc/mysql/my.cnf /etc/mysql/my.cnf.bak
3. sudo cp /etc/mysql/debian.cnf /etc/mysql/debian.cnf.bak
4. sudo vim /etc/mysql/my.cnf
   1. replace every line starting with “socket =” by “socket = /tmp/mysql.sock”
5. sudo vim /etc/mysql/debian.cnf
   1. replace every line starting with “socket =” by “socket = /tmp/mysql.sock”
6. sudo service mysql start

in the Zend Server CE admin (http://localhost:10081/ZendServer/) > Server Setup > Directives >
Search for default_socket and in mysql and mysqli remove the content of the textarea (empty value => default value used instead)
Then click Save Changes and click Restart PHP

It will work until Zend Server CE bug is fixed (release 5.0).

Sometimes it happens…

Solution: locate the .channels/ directory
For ubuntu with Zend-CE 5.2 it’s in /usr/local/zend/share/pear/.channels/

And delete everything in there

sudo rm /usr/local/zend/share/pear/.channels/*

then do a fresh pear update-channels to reconstruct the serialized cache file in .channels/

sudo pear update-channels

if you also want to also install phpunit


cd /usr/local/zend/bin/
sudo ./pear channel-discover pear.phpunit.de
sudo ./pear install phpunit/PHPUnit
