#################centos7下mysql的解除安裝####################
1：檢視mysql是否安裝:
方式1:
[plain]view plain
copy
[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)：
[plain]view plain
copy
[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：
[plain]view plain
copy
[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：
[plain]view plain
copy
[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:
[plain]view plain
copy
[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：
[plain]view plain
copy
[root@localhost usr]# whereis mysql
mysql: /usr/lib64/mysql
[root@localhost usr]# rm -rf /usr/lib64/mysql
注：find / -name mysql (rm -rf 相關的的目錄)
注：清空相關mysql的所有目錄以及檔案和其他配置和設定等。如果有，則刪除。也必須考慮其他軟體不去影響。
rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql
解除安裝4
：
[plain]view plain
copy
[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）：
[plain]view plain
copy
[root@localhost usr]# chkconfig --list | grep -i mysql
[root@localhost usr]# chkconfig --del mysqld
[plain]view plain
copy
此處刪除看自己設定:mysql/mysqld
