对于在Linux下通过rpm方式安装的mysql，我们可以通过移除这些rpm包以及删除项目的目录来达到卸载的目的。本文演示了在SUSE Linux 10下卸载MySQL 5.5.37。具体见下文。

1、环境

代码如下:

#OS环境

SZDB:~ # cat /etc/issue

Welcome to SUSE Linux Enterprise Server 10 SP3 (x86_64) - Kernel \r (\l).

#查看已安装的安装包

SZDB:~ # rpm -qa | grep -i mysql

MySQL-devel-5.5.37-1.sles10

MySQL-server-5.5.37-1.sles10

MySQL-shared-compat-5.5.37-1.sles10

MySQL-client-5.5.37-1.sles10

MySQL-shared-5.5.37-1.sles10

MySQL-test-5.5.37-1.sles10

MySQL-embedded-5.5.37-1.sles10

2、停止mysql服务

代码如下:

SZDB:~ # /etc/init.d/mysql stop

Shutting down MySQL. done

3、使用rpm卸载mysql

代码如下:

SZDB:~ # rpm -e --nodeps MySQL-server-5.5.37-1.sles10

insserv: script postgresqlMemory: service postgresql already provided!

insserv: script postgresql: service postgresql already provided!

mysql 0:off 1:off 2:off 3:off 4:off 5:off 6:off

#使用下面的方式移除所有mysql rpm包

SZDB:~ # rpm -e --nodeps MySQL-client-5.5.37-1.sles10

SZDB:~ # rpm -e --nodeps MySQL-devel-5.5.37-1.sles10

SZDB:~ # rpm -e --nodeps MySQL-shared-compat-5.5.37-1.sles10

SZDB:~ # rpm -e --nodeps MySQL-shared-5.5.37-1.sles10

SZDB:~ # rpm -e --nodeps MySQL-test-5.5.37-1.sles10

SZDB:~ # rpm -e --nodeps MySQL-embedded-5.5.37-1.sles10

4、移除相关mysql目录及文件

代码如下:

SZDB:~ # find / -name mysql

/etc/apparmor.d/abstractions/mysql

/var/lib/mysql

/var/lib/mysql/mysql

/usr/lib64/mysql

/usr/local/quickfix_old/src/sql/mysql

SZDB:~ # rm -rf /etc/apparmor.d/abstractions/mysql

SZDB:~ # rm -rf /var/lib/mysql

SZDB:~ # rm -rf /var/lib/mysql/mysql

SZDB:~ # rm -rf /usr/lib64/mysql

SZDB:~ # rm -rf /usr/local/quickfix_old/src/sql/mysql

SZDB:~ # ls /etc/my*

/bin/ls: /etc/my*: No such file or directory

注，如果/etc目录下有my.cnf，也做相应移除

根据需要考虑是否移除linux下的mysql 用户

代码如下:

SZDB:~ # cat /etc/passwd | grep mysql

mysql:x:104:106:MySQL server:/var/lib/mysql:/bin/bash

5、校验结果

代码如下:

SZDB:~ # rpm -qa | grep -i mysql

SZDB:~ # chkconfig --list |grep mysql
