????對于在Linux下通過rpm方式的mysql，我們能夠通過移除這些rpm包以及刪除項目的文件夾來達到卸載的目的。本文演示了在SUSE Linux 10下下載MySQL 5.5.37。詳細見下文。

?

1、環境
#OS環境
SZDB:~ # cat /etc/issue

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

#查看已安裝的安裝包
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服務
SZDB:~ # /etc/init.d/mysql stop?
Shutting down MySQL.????????????? done

?

3、使用rpm卸載mysql
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

#使用以下的方式移除全部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、移除相關mysql文件夾及文件
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，假設/etc文件夾下有my.cnf，也做對應移除
依據須要考慮是否移除linux下的mysql 用戶
SZDB:~ # cat /etc/passwd | grep mysql
mysql:x:104:106:MySQL server:/var/lib/mysql:/bin/bash

?

5、校驗結果
SZDB:~ # rpm -qa | grep -i mysql
SZDB:~ # chkconfig --list |grep mysql
