2.检查库文件是否存在，如有删除。
[root@yangliao ~]# rpm -qa | grep mysql
mysql-libs-5.1.52-1.el6_0.1.x86_64
[root@yangliao ~]# rpm -e mysql-libs-5.1.52.x86_64 --nodeps
3.检查mysql组和用户是否存在，如无创建。
[root@yangliao ~]# cat /etc/group | grep mysql
如果用户不存在就创建用户
[root@yangliao ~]# groupadd mysql
[root@yangliao ~]# useradd -r -g mysql mysql
[root@yangliao ~]# cat /etc/group | grep mysql
mysql:x:1000:
[root@yangliao ~]# cat /etc/passwd | grep mysql
mysql:x:997:1000::/home/mysql:/bin/bash
4.解压TAR包，更改所属的组和用户
[root@yangliao ~]# tar -zxvf mysql-5.7.21-linux-glibc2.12-x86_64.tar.gz

启动MySQL服务时，会优先在/etc/目录下查找my.cnf
使用源码MySQL，安装目录为/usr/local/mysql/，相关配置文件都保存在此目录。并且有检查/etc/my.cnf文件是否存在(存在就将其重命名/删除)
[root@yangliao etc]#
[root@yangliao etc]# mv /etc/my.cnf /etc/my.cnf.bak
[root@yangliao etc]#
[root@yangliao etc]#
[root@yangliao etc]# /usr/local/mysql/support-files/mysql.server start
Starting MySQL.Logging to '/usr/local/mysql/data/yangliao.err'.
[ OK ]
[root@yangliao etc]#
[root@yangliao etc]#
[root@yangliao etc]#
[root@yangliao etc]# /usr/local/mysql/bin/mysql -uroot -p
