请教MYSQL安装问题

shuiniuyitiao

我使用ROOT用户安装mysql-5.0.45，如下：
# tar xzvf mysql-5.0.45-linux-i686-glibc23.tar.gz
# mv mysql-5.0.45-linux-i686-glibc23 /usr/local/
# ln -s /usr/local/mysql-5.0.45-linux-i686-glibc23 /usr/local/mysql
# useradd mysql
# chown -R mysql:root /usr/local/mysql/
# cd /usr/local/mysql
# ./scripts/mysql_install_db --user=mysql
# cp ./support-files/mysql.server /etc/rc.d/init.d/mysqld
# chown root:root /etc/rc.d/init.d/mysqld
# chmod 755 /etc/rc.d/init.d/mysqld
# chkconfig --add mysqld
# chkconfig --level 3 5 mysqld on
# cp ./support-files/my-huge.cnf /etc/my.cnf
# mv /usr/local/mysql/data /var/lib/mysql
# chown -R mysql:mysql /var/lib/mysql/
# vi /etc/my.cnf

最后service mysqld start，出现如下错误，
Starting MySQL/etc/init.d/mysqld: line 159: kill: (2229) - No such process

请大家帮小弟看看，3Q3Q!
