RedHat下安装MySQL5.5

MYSQL在windows下面安装可能一帆风顺，但是如果真的到纯图形界面的redhat服务器上，可能就不是那么容易了，这里我就详细的介绍一下MYSQL5.5在linux下的安装以及注意的问题，避免后来人犯错。

工具/原料

   linux - Redhat

   MySQL-5.5.39-2.el6.x86_64.rpm-bundle.tar

   shell控制台

方法/步骤

   下载mysql5.5的安装包。这里下载的是MySQL-5.5.39-2.el6.x86_64.rpm-bundle.tar

   解压mysql5.5的安装包

   tar -xvf MySQL-5.5.39-2.el6.x86_64.rpm-bundle.tar

   注意的是要切换的root用户  使用 su root切换用户

   解压之后就是出现了好多的rpm文件

在这些文件中我们要安装的就是下面的3个，这个地方注意了。

MySQL-client-5.5.39-2.el6.x86_64.rpm

MySQL-devel-5.5.39-2.el6.x86_64.rpm

MySQL-server-5.5.39-2.el6.x86_64.rpm

安装过程较快，除了MySQL-server-5.5.39-2.el6.x86_64.rpm稍微慢一些。

其他两个十分的快

使用的命令是

rpm - ivh   *.rpm

这里我们看到安装MySQL-server-5.5.39-2.el6.x86_64.rpm时没有错误，但是如果linux系统默认自带了较低版本的mysql，那么此时就会报错，类似如下错误信息：

原因是系统已经安装了其他版本的mysql-libs包导致不兼容。

删除mysql-libs

[root@localhost ~]# yum remove mysql-libs

执行成功之后，再次安装MySQL-server-5.5.39-2.el6.x86_64.rpm就ok了。

接着就是初始化数据库。十分简单 /usr/bin/mysql_install_db

接下来就是查看mysql的状态，并设置mysql的初始密码，见下图。

好了，5步下来我们的mysql就安装完毕。是不是很简单啊。哈哈

但是我们有时候在执行service mysql status时候会提示mysql服务没有启动，那么我们手动启动一下mysql:

service mysql start(停止mysql服务的命令service mysql stop)。

至此，rehat下安装mysql5.5已经完毕。
