安装不了，用rpm -qa|grep -i mysql查看发现centos中虽然以前没有安装过mysql但里面还是安装了[root@***-3 soft]# rpm -qa|grep -i mysqlmysql-libs-5.1.52-1.el6_0.1.x8
[root@***-3 soft]# rpm -qa|grep -i mysql
mysql-libs-5.1.52-1.el6_0.1.x86_64
然后用命令
[root@***-3 soft]# yum -y remove mysql mysql-*

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 xu-3 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 with the /usr/bin/mysqlbug script!
