在Centos6.5环境上使用yum -y install mysql 安装的是MySQL5.1
先卸载MySQL5.1
查找 rpm -qa|grep mysql
[root@mysql ~]# rpm -qa|grep mysql
mysql-libs-5.1.71-1.el6.x86_64
卸载:rpm -e mysql-libs-5.1.71-1.el6.x86_64 --nodeps
如果有多个mysql-**的话 就多执行一下命令。
想要安装MySQL6.5 要经过一些改造。

# yum install mysql-community-server
这时安装时会报:
warning: rpmts_HdrFromFdno: Header V3 DSA signature: NOKEY
由于yum安装了旧版本的GPG keys造成的
接下来需要做:
gpg --import /etc/pki/rpm-gpg/RPM*
rpm --import /etc/pki/rpm-gpg/RPM*
就不会报错了。
再执行
yum install mysql-community-server就能进行安装了。
安装完成后使用
service mysqld start #启动服务
设置root密码
/usr/bin/mysqladmin -u root password 123456
mysql -uroot -p 123456
解决。
