发现冲突，问题原因是安装操作系统时，选中了默认的mysql。

4.再次安装mysql：
[root@mysql share]# rpm -q mysql
package mysql is not installed
[root@mysql share]# cd /mysql
[root@mysql mysql]# ls
lost+found  MySQL-client-5.5.38-1.linux2.6.x86_64.rpm  MySQL-server-5.5.38-1.linux2.6.x86_64.rpm
[root@mysql mysql]# rpm -ivh MySQL-server-5.5.38-1.linux2.6.x86_64.rpm
Preparing...                ########################################### [100%]
   1:MySQL-server           ########################################### [100%]

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 mysql 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.

Please report any problems at http://bugs.mysql.com/
