1、檢視mysql是否安裝

方式1:

[root@localhost usr]# yum list installed mysql*


loaded plugins: fastestmirror


loading mirror speeds from cached hostfile


* base: mirrors.yun-idc.com


* extras: mirror.neu.edu.cn


* updates: mirrors.yun-idc.com


installed packages


mysql-client.x86_64   5.6.27-1.el6    installed


mysql-devel.x86_64    5.6.27-1.el6    installed


mysql-server.x86_64   5.6.27-1.el6    installed


[root@localhost usr]#
方式2(

-i  :不區分大小寫

)：

[root@localhost usr]# rpm -qa | grep -i mysql


mysql-server-5.6.27-1.el6.x86_64


mysql-client-5.6.27-1.el6.x86_64


mysql-devel-5.6.27-1.el6.x86_64


[root@localhost usr]#
2、解除安裝mysql

解除安裝1：

[root@localhost usr]# yum remove mysql mysql-server mysql-libs compat-mysql51


[root@localhost usr]# rm -rf /var/lib/mysql


[root@localhost usr]# rm /etc/my.cnf
如果裝了mysql-devel(其他一樣add command)，解除安裝為：

[root@tony_ts_tian init.d]# yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51
注（例如）:

mysql-5.5.39-1.el6.remi.x86_64

mysql-libs-5.5.39-1.el6.remi.x86_64

compat-mysql51-5.1.54-1.el6.remi.x86_64

mysql-server-5.5.39-1.el6.remi.x86_64

解除安裝2:

[root@localhost mysql]# rpm -aq | grep -i mysql


mysql-server-5.6.27-1.el6.x86_64


mysql-client-5.6.27-1.el6.x86_64


mysql-devel-5.6.27-1.el6.x86_64


[root@localhost mysql]# rpm -e mysql-server-5.6.27-1.el6.x86_64


[root@localhost mysql]# rpm -e mysql-client-5.6.27-1.el6.x86_64


[root@localhost mysql]# rpm -e mysql-devel-5.6.27-1.el6.x86_64


[root@localhost rc.d]# cd /var/lib/


[root@localhost lib]# rm -rf mysql/

注:刪除mysql資料庫目錄(關鍵) ，否則password不更新（預設安裝，如果自定義安裝路徑和鏈結路徑ln -s ……請刪除。）

rm -rf /var/lib/mysql

解除安裝3：

[root@localhost usr]# whereis mysql


mysql: /usr/lib64/mysql


[root@localhost usr]# rm -rf /usr/lib64/mysql
注：find / -name mysql

rm -rf /usr/lib/mysql

rm -rf /usr/share/mysql

解除安裝4

：

[root@localhost usr]# rm –rf /usr/my.cnf


[root@localhost usr]# rm -rf /root/.mysql_sercret
解除安裝5（自啟服務）：

[root@localhost usr]# chkconfig --list | grep -i mysql


[root@localhost usr]# chkconfig --del mysqld
此處刪除看自己設定:mysql/mysqld
