[Koha] ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/*mysqld/mysqld.sock' (2)

[Samuel Desseaux]

Hi

I have a problem while installing koha on a machine (i install with 
debian package)

I have this message "ERROR 2002 (HY000): Can't connect to local MySQL 
server through socket '/var/run/*mysqld/mysqld.sock' (2)"

What i don't understand is

 >mysql well running

$ service mysql status

 >no problem when i restart

$ service mysql restart
Stopping MySQL database server: mysqld.
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..

But, the problem could come from that

$locate libmysqlclient.so
/usr/lib/libmysqlclient.so.16
/usr/lib/libmysqlclient.so.16.0.0

As the debian package include mysql-server5.1, there may be a conflict.

How can i fix this problem?

best regards
