现想要在这家的服务器上安装Mysql集群，发现之前安装操作系统的时候顺便把MySql默认安装，所以需要将它先卸载掉。

1,查找已安装的mysql版本

\[root@leader ~\]\# rpm -qa|grep mysql  
qt-mysql-4.6.2-28.el6\_5.x86\_64  
mysql-server-5.1.73-3.el6\_5.x86\_64  
mysql-libs-5.1.73-3.el6\_5.x86\_64  
mysql-devel-5.1.73-3.el6\_5.x86\_64  
mysql-connector-odbc-5.1.5r1144-7.el6.x86\_64  
mysql-5.1.73-3.el6\_5.x86\_64

2.查看mysql运行状态及mysql版本信息和进程信息

\[root@leader ~\]\# service mysqld status  
mysqld (pid 20327) is running...  
\[root@leader ~\]\# mysql --version  
mysql Ver 14.14 Distrib 5.1.73, for redhat-linux-gnu (x86\_64) using readline 5.1  
\[root@leader ~\]\# ps -aux|grep mysql  
Warning: bad syntax, perhaps a bogus '-'? See /usr/share/doc/procps-3.2.8/FAQ  
root 20219 0.0 0.0 108204 1448 pts/0 S 05:56 0:00 /bin/sh /usr/bin/mysqld\_safe --datadir=/var/lib/mysql --socket=/var/lib/mysql/mysql.sock --pid-file=/var/run/mysqld/mysqld.pid --basedir=/usr --user=mysql  
mysql 20327 0.0 1.3 377852 25344 pts/0 Sl 05:56 0:06 /usr/libexec/mysqld --basedir=/usr --datadir=/var/lib/mysql --user=mysql --log-error=/var/log/mysqld.log --pid-file=/var/run/mysqld/mysqld.pid --socket=/var/lib/mysql/mysql.sock  
root 21575 0.0 0.0 103252 840 pts/3 S+ 11:47 0:00 grep mysql

\[root@leader ~\]\# chkconfig --list mysqld  
mysqld 0:off 1:off 2:off 3:off 4:off 5:off 6:off

3.卸载mysql

3.1 停止mysql运行

\[root@leader ~\]\# service mysqld stop  
Stopping mysqld: \[ OK \]  
\[root@leader ~\]\# service mysqld status  
mysqld is stopped

3.2卸载mysql,根据rpm qa结果数进行，打印信息忽略。

\[root@leader ~\]\# yum -y remove qt-mysql-4.6.2-28.el6\_5.x86\_64

\[root@leader ~\]\# yum -y remove mysql-server-5.1.73-3.el6\_5.x86\_64

\[root@leader ~\]\# yum -y remove mysql-libs-5.1.73-3.el6\_5.x86\_64

\[root@leader ~\]\# yum -y remove mysql-devel-5.1.73-3.el6\_5.x86\_64

\[root@leader ~\]\# yum -y remove mysql-connector-odbc-5.1.5r1144-7.el6.x86\_64

\[root@leader ~\]\# yum -y remove mysql-5.1.73-3.el6\_5.x86\_64

3.3执行上述命令后，验证检查结果
