Re: [rock-user] Re : Re : Mysql installation cannot connect, cannot start

Hi Philippe,

To make the steps clear, I give a summary what to do.

1. Run the command mysql_init_db (this should also create the directory
(/var/opt/mysql) as root [This initialize the System-DB where MySQL
stores the users and so on]
2. Do a "chown -R mysql:mysql /var/opt/mysql" for changing the owner to
the correct user [MySQL is running as user mysql so the databases must
be owned by mysql]
3. Try /opt/mysql/bin/mysqld_safe. If it still isn't running, look at
/var/opt/mysql/<hostname>.err [This is the final check if steps 1 and 2
were sucessfull]

After these steps a "/etc/init.d/mysql start" should work.

Regards,
Michael Obster
