##卸载系统自带的mysql
[root@db01 ~]# rpm -qa|grep mysql
mysql-libs-5.1.73-7.el6.x86_64
[root@db01 ~]# rpm -e --nodeps mysql-libs-5.1.73-7.el6.x86_64
[root@db01 ~]# rpm -qa|grep mysql
[root@db01 ~]#
##安装相关的依赖包
[root@db01 ~]# yum install gcc bison ncurses ncurses-devel zlib libxml2 openssl libaio -y
[root@db01 ~]# rpm -qa gcc bison ncurses ncurses-devel zlib libxml2 openssl libaio

##创建mysql用户，UID为800，不让其登录，不创建家目录
[root@db01 ~]# useradd -u800 -s /sbin/nologin -M mysql
[root@db01 ~]# id mysql
uid=800(mysql) gid=800(mysql) groups=800(mysql)
##创建相应的目录
[root@db01 ~]# mkdir /apps /data/3306/{data,binlog,errlog,slowlog,relaylog,redolog} -p
[root@db01 ~]# ls -ld /apps/
drwxr-xr-x 2 root root 4096 Dec 1 20:10 /apps/
[root@db01 ~]# tree /data/3306/

1.5 编辑启动脚本
注意：
01：该脚本中停用mysql的方法为：mysqladmin -uroot -pchenliang -S /data/3306/mysql.sock shutdown
02：如果你的mysql服务的root用户密码设置的不是chenliang
03：请你更改/data/3306/mysqld脚本中的Pass变量的值

1.6 后期安装步骤
#更改/data/3306/mysqld文件的权限为700

-rw-r--r-- 1 root root 0 Dec 1 21:47 /data/3306/errlog/mysql_error.log
##更改/data/3306/目录及子目录下的文件属主/组为mysql用户
[root@db01 ~]# chown -R mysql:mysql /data/3306/
[root@db01 ~]# ls -ld /data/3306/

Start MySQL [3306] [ OK ]
[root@db01 ~]# netstat -lntup|grep 3306

##修改root@localhost的密码
[root@db01 ~]# grep "password" /data/3306/errlog/mysql_error.log
