CentOS中安装MySQL数据库
1、首先下载MySQL的安装文件，我这里安装的是MySQL5.1.7版本的，

2、安装MySQL数据库服务器
进入安装包所在文件夹，执行命令 rpm -ivh MySQL-server-5.1.7-0.i386.rpm 安装MySQL服务器。
如果报了与原先版本冲突的话，就执行rpm -qa|grep -i mysql命令，会显示已安装的Mysql版本,我的显示mysql-libs-5.1.61-4.el6.i686
这时如果有的话就强制删除：rpm -e --nodeps mysql-libs-5.1.61-4.el6.i686（因为有包依赖，所以要强制删除）
我的报错提示如下：

这时候再执行rpm -ivh MySQL-server-5.1.7-0.i386.rpm安装即可安装成功。
我这里安装成功了，但是mysql服务无法启动，总是启动失败，后来百度了一下，是因为selinux的原因，只要将selinux关闭就OK了。
关闭selinux：vi /etc/selinux/config 将SELINUX=enforcing 改成SELINUX=disabled 然后重启
关闭selinux之后还是无法启动mysql服务，因为安装的mysql所有者是root，在安装mysql的时候会创建一个用户mysql，只要将/var/lib/mysql
的所有者改为mysql就OK了，执行命令chown -R mysql:mysql /var/lib/mysql
现在执行service mysql start终于可以启动mysql服务了。
3.安装MySQL客户端
执行命令rpm -ivh MySQL-client-5.1.7-0.i386.rpm进行安装。
4.安装成功
成功安装MySQL后将sql文件导入到数据库，步骤如下：
进入MYSQL Command Line Client
1、先创建数据库：create database test 注：test是创建数据库的名称
2、再切换到当前数据库：use test
3、再输入：. /root/test.sql 或 souce /root/test.sql
按照以上步骤就可以将备份的sql脚本导入到linux中的数据库中去。
