CentOS 6.9安装MySQL 5.6 （使用yum安装）

移除CentOS默认的mysql-libs

[root@test01 srv]# whereis mysql
mysql: /usr/lib64/mysql /usr/share/mysql
[root@test01 srv]#

为了避免冲突，先移除CenttOS上默认的mysql-libs，使用yum remove mysql-libs完成，如：
[root@test01 srv]# yum remove mysql-libs

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h test01.znyj.interconnect password 'new-password'

Alternatively you can run:

/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.

See the manual for more instructions.
