Hi!
Looks like you've got quite a few things going wrong. Firstly, can you check that you have a mysql user defined on your system given the following error message:
090825 10:15:42 [ERROR] Fatal error: Can't change to run as user 'mysql' ; Please check that the user exists!
Next, how are you starting mysqld?
Also, please execute the following on your shell prompt:
shell> ps -ef | grep mysql
Also provide your my.cnf file
Lastly, looks like there are some right issues on your system, likely during the installation and now:
090825 10:15:42 [ERROR] Can't find messagefile '/usr/share/mysql/english/errmsg.sys'
090825 10:15:42 [Warning] Can't create test file /var/lib/mysql/linux-s9iv.lower-test
090825 10:15:42 [Warning] Can't create test file /var/lib/mysql/linux-s9iv.lower-test
As which user did you try to install the rpm packages?
Maybe also provide a:
shell> ls -l /var/lib/mysql/
shell> ls -l /usr/share/mysql/english/
shell> ls -l /etc/mysql/
shell> ls -l /usr/bin/
shell> ls -l /usr/sbin/
Not sure about the insserv errors, may have to check Suse site for that.
