另外启动一个窗口,/etc/profile文件修改添加一句话export PATH=/usr/local/mysql/bin:$PATH

vim /etc/profile的过程省略

[root@iZwz94knyxhkgqeu5pve0zZ ~]# source /etc/profile

[root@iZwz94knyxhkgqeu5pve0zZ ~]# chmod 755 /etc/init.d/mysql

[root@iZwz94knyxhkgqeu5pve0zZ ~]# chkconfig --add mysql

[root@iZwz94knyxhkgqeu5pve0zZ ~]# chkconfig --level 345 mysql on
