Can't connect to local MySQLserver through socket/var/run/mysqld/mysqld.sock

its sound like permission problem..

Check the permission for mysqld and mysql.sock

see those are define to mysql or somethign else

or  as @racmail2001 advise, Create a new one with mysql permission on

root@marietto2009:/var/run/mysqld# sudo touch /var/run/mysqld/mysqld.sock
root@marietto2009:/var/run/mysqld# sudo chown mysql /var/run/mysqld
root@marietto2009:/var/run/mysqld# sudo chown mysql /var/run/mysqld/mysqld.sock
root@marietto2009:/var/run/mysqld# sudo mysqld
090814 10:44:56  InnoDB: Started; log sequence number 0 43665
090814 10:44:56 [ERROR] Can't start server: Bind on TCP/IP port: Cannot assign requested address
090814 10:44:56 [ERROR] Do you already have another mysqld server running on port: 3306 ?
090814 10:44:56 [ERROR] Aborting

do this

ps aux | grep -v grep | grep mysqld

or

ps aux | grep -v grep | mysql

see if it returns anything
if it returns anything that means your mysql server is already running

sorry it would be


ps aux | grep -v grep | grep  mysql

marietto2008.ath.cx is a free domain name that I've got from www.dyndns.org

ps aux | grep -v grep | grep  mysql ---> return nothing

What about this output

lsof -i:3306


also

ps aux | grep -v grep | grep  mysqld

root@marietto2009:/var/run/mysqld# lsof -i:3306
root@marietto2009:/var/run/mysqld# ps aux | grep -v grep | grep  mysqld

also

can you try to start mysql with full command

/etc/init.d/mysql start
/etc/init.d/mysql stop

also disable this line

bind-address            = marietto2008.ath.cx

to

#bind-address            = marietto2008.ath.cx

root@marietto2009:/var/run/mysqld# /etc/init.d/mysql start
 * Starting MySQL database server mysqld                                 [ OK ]
 * Checking for corrupt, not cleanly closed and upgrade needing tables.
root@marietto2009:/var/run/mysqld# /etc/init.d/mysql stop
 * Stopping MySQL database server mysqld                                 [ OK ]
root@marietto2009:/var/run/mysqld#

so according to this post ( your last post)

ID:25096260

mysql server is running then  , its not it ??

nope,because the last line you said,has been :

/etc/init.d/mysql stop

You welcome
