在linux安装mysql是一个困难的事情,yum安装一般是安装的mysql5.1,现在经过自己不懈努力终于能用yum安装mysql5.5了。下面通过两种方法给大家介绍CentOS 6.5下yum安装 MySQL-5.5全过程,一起学习吧。

方法一:

具体方法和步骤如下所示:

1.第一步就是看linu是否安装了mysql,经过rpm -qa|grep mysql查看到centos下安装了mysql5.1,那就开始卸载咯

2.接下来就是卸载mysql5.1了,命令:rpm -e mysql-libs --nodeps

3.yum中之后mysql5.1,安装还是5.1,现在就要去增加一个新的repo

rpm -Uvh http://mirror.steadfast.net/epel/6/i386/epel-release-6-8.noarch.rpm

4.一共需要增加两个repo,现在增加另一个

rpm -Uvh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm

5.现在查看一些是否增加成功了,yum --enablerepo=remi,remi-test list mysql mysql-server

看到下面这些就是安装成功了。

6.接下来就是安装mysql5.5了

yum --enablerepo=remi,remi-test install mysql mysql-server

7.出现这个东西的时候一定要选择y。不然神都救不了你,就要重新安装了。

8.看到下面这个图片证明你的mysql安装成功了。

9.接下来需要启动一下mysql

/etc/init.d/mysqld start

10.下面这条命令设置开机自启动,省的我们每次开机就去启动一下mysql了。

chkconfig --levels 345 mysqld on

11.要启用MySQL 安全设置请输入以下命令

/usr/bin/mysql_secure_installation

12.到这里就要验证一下mysql是否安装成功了。如果输入看到以下界面的话,那么你就安装成功了。犒劳一下自己吧。
