请问大虾：我装完MYSQL后，都要运行哪些程序？

请告诉我顺序，谢谢了
我是先运行safe_mysqld &
可结果提示：
touch: creating `/home/zhangxc/mysql/var/RHLinux.err': No such file or directory
chown: `mysql': invalid user
Starting mysqld daemon with databases from /home/zhangxc/mysql/var
./safe_mysqld: /home/zhangxc/mysql/var/RHLinux.err: No such file or directory
./safe_mysqld: /home/zhangxc/mysql/var/RHLinux.err: No such file or directory
tee: /home/zhangxc/mysql/var/RHLinux.err: No such file or directory
030721 21:30:17  mysqld ended
tee: /home/zhangxc/mysql/var/RHLinux.err: No such file or directory


RHLinux是我的主机名
怎么回事啊？
