Mysql starting error: ... STOPPING server from pid file /var/lib/mysql/roboo-lvzg.pid , mysqld ended

When I start mysqld server (in slackware linux 11), got error as follows:

root@kseeker-lvzg:~# mysqld_safe --user='mysql' &

[1] 10624

root@kseeker-lvzg:~# Starting mysqld daemon with databases from /var/lib/mysql

STOPPING server from pid file /var/lib/mysql/kseeker-lvzg.pid

070129 18:55:45 mysqld ended

oh, you need to su mysql and run mysql_install_db to fix the problem.

root@kseeker-lvzg:~# su mysql

mysql@kseeker-lvzg:/root$ mysql_install_db

To start mysqld at boot time you have to copy support-files/mysql.server

to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'

/usr/bin/mysqladmin -u root -h kseeker-lvzg password 'new-password'

See the manual for more instructions.

You can start the MySQL daemon with:

cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with the benchmarks in the 'sql-bench' directory:

cd sql-bench ; perl run-all-tests

Please report any problems with the /usr/bin/mysqlbug script!
