redhat Enterprise 5 自帶一個mysql的版本,將其卸載,步驟如下：
a. 查找已安裝的myslq 版本：
?MYSQL學習

#rpm? -qa | grep? mysql (注意大小寫,如果mysql 不行就換MySQL)
?

出現：
?MYSQL學習

[root@jbxue mysql]$ rpm? -qa | grep? mysql
mysql-5.0.45-7.el5
libdbi-dbd-mysql-0.8.1a-1.2.2
mysql-5.0.45-7.el5
mysql-server-5.0.45-7.el5
mysql-connector-odbc-3.51.12-2.2
?

卸載命令：
?MYSQL學習

//卸載已安裝的mysql
# rpm –e mysql-*
?

卸載后/var/lib/mysql中的數據及/etc/my.cnf不會刪除,如果確定沒用后就手工刪除
?MYSQL學習

rm -f /etc/my.cnf
rm -rf /var/lib/mysql
?

或參考：系統 CentOS4.3
安裝方法
#yum -y install mysql-server
mysql版本
mysql-server.i386-4.1.20-1.RHEL4.1MYSQL學習

刪除方法：
?MYSQL學習

#yum -y remove mysql-server
#yum -y remove mysql

然后,再輸入命令：
?MYSQL學習

[root@jbxue mysql]$ sudo yum -y remove mysql-5.0.45-7.el5

到此,Linux下自帶的mysql已經完全卸載,此時,再輸入：
?MYSQL學習

[root@jbxue mysql]$ rpm? -qa | grep? mysql
[root@jbxue mysql]$

顯示系統已經沒有mysql服務；
?MYSQL學習
