    I keep getting the following warning email:

    Warning: service mysqld not running (server:

    When I login to my server MySQL is running. I am running debian 3.1 I believe. The name of the file in /etc/init.d/ is mysql, not mysqld. However, whenever I do a ps -aux|grep mysqld I find three instances of MySQL running. Everything seems to be running just fine right now also.

    Any ideas?

    Looks ok. What's in /etc/hosts? What's the output of
    ps -aux|grep mysql
    grep mysql /etc/services

    Looks ok, too. :confused:
    Did you try and restart the server?

    Restart Server

    Not yet, but I will. Can you give me an idea of where to look in code and I will see if I can spot the problem. You don't have to tell me exactly, I just don't know which file monitors the services.

    Please make sure your mysql server listens on a TCP socket on too.

    Hi people, i'm having a similar problem with mysqld (Ver 5.0.30-Debian_0.dotdeb.1-log for pc-linux-gnu on i386 (Dotdeb Sarge backport).

    I start the server everythin is working good, then someday with no reason i cannot access to my blogs because it sez that my mysql server is down.. so, i do a ps xau |grep mysqld and i see it's runnin, so i run /etc/init.d/mysql stop

    And this is what i get:

    Stopping MySQL database server: mysqld...failed.
    /usr/bin/mysqladmin: connect to server at 'localhost' failed
    error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (11)'
    Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
    Killing MySQL database server by signal: mysqld...failed.
    Please stop MySQL manually and read /usr/share/doc/mysql-server/README.Debian!
    I also verified that mysqld.sock was 'running' and located in the right path.

    Finally, i have to killall mysqld, and restart the mysql daemon and everything starts to work just fine again. This is happenin since i upgraded my mysql server to version 5 of dotdeb.

    Waitin for ideas, thx in advance.

    You can try this:
    rm -f /var/run/mysqld/*
    and then reboot your server.

    Then I guess there's something wrong with your new MySQL server... :( Maybe there's an updated package that you can install?

    I have the same problem. I receive email "service not running" every 30mn while mysql is running

    I upgrade PHP and MYSQL from dotdeb (from mysql 4.0.24 to mysql 4.1.15)
    It works without problem during 1 week

    I restart mysql one day and the problems begins
    I think there was confusion beetween mysql 4.0.24 and 4.1.15 because it doesn't recognize 4.1.15 parameters like old_passwords and expire_log_days.

    I comment those parameters in my.cnf and it works but with 4.0.24 !
    And I receive this error email since.
