I have a brand new Ubuntu 12.04 server and installed Percona Server from the apt repo from percona.com.
It all installed fine but will not complete starting using the “service mysql start” command.
The server is started though and listening on IP but I get the following error when trying the following…
mysqladmin --defaults-file=/etc/mysql/debian.cnf ping
mysqladmin: connect to server at ‘localhost’ failed
error: ‘Can’t connect to local MySQL server through socket ‘/var/run/mysqld/mysqld.sock’ (2)’
Check that mysqld is running and that the socket: ‘/var/run/mysqld/mysqld.sock’ exists!
Seems to be an issue with the socket which is created with permissions wide open.
