今天数据库服务器可以使用了，现在下一步就是安装mysql，，决定mysql 版本为5.6.14
检查系统中是否已经安装过mysql。rpm -qa | grep mysql如下图：
如果存在，则需要删除。yum -y remove mysql*继续检查一下是否还存在mysqlrpm -qa | grep -i mysql
然后下一步就是下载rpm包了。需要下载：MySQL-client-5.6.15-1.el6.x86_64.rpmMySQL-devel-5.6.15-1.el6.x86_64.rpmMySQL-server-5.6.15-1.el6.x86_64.rpm逐一执行命令：wget wget wget
接下来就是安装了分别依次执行：[root@iZ25in7iu0fZ rpm]# rpm -ivh MySQL-server-5.6.15-1.el6.x86_64.rpmPreparing… ########################################### [100%] 1:MySQL-server ########################################### [100%]2015-03-06 08:16:03 0 [Warning] TIMESTAMP with implicit DEFAULT value is deprecated.
