#################CentOS7下MySQL的卸載####################

1：查看MySQL是否安裝:

方式1:

[plain] view plain copy

1. [root@localhost usr]# yum list installed mysql*
2. Loaded plugins: fastestmirror
3. Loading mirror speeds from cached hostfile
4. * base: mirrors.yun-idc.com
5. * extras: mirror.neu.edu.cn
6. * updates: mirrors.yun-idc.com
7. Installed Packages
8. MySQL-client.x86_64 5.6.27-1.el6 installed
9. MySQL-devel.x86_64 5.6.27-1.el6 installed
10. MySQL-server.x86_64 5.6.27-1.el6 installed
11. [root@localhost usr]#

方式2( -i :不區分大小寫)：

[plain] view plain copy

1. [root@localhost usr]# rpm -qa | grep -i mysql
2. MySQL-server-5.6.27-1.el6.x86_64
3. MySQL-client-5.6.27-1.el6.x86_64
4. MySQL-devel-5.6.27-1.el6.x86_64
5. [root@localhost usr]#

2：卸載MySQL:

卸載1：

[plain] view plain copy

1. [root@localhost usr]# yum remove mysql mysql-server mysql-libs compat-mysql51
2. [root@localhost usr]# rm -rf /var/lib/mysql
3. [root@localhost usr]# rm /etc/my.cnf

如果裝了mysql-devel(其他一樣add command)，卸載為：

[plain] view plain copy

1. [root@Tony_ts_tian init.d]# yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51

註（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 卸載2{繼續，1，2選擇一種（此處為介紹）：}: [plain] view plain copy

1. [root@localhost mysql]# rpm -aq | grep -i mysql
2. MySQL-server-5.6.27-1.el6.x86_64
3. MySQL-client-5.6.27-1.el6.x86_64
4. MySQL-devel-5.6.27-1.el6.x86_64
5. [root@localhost mysql]# rpm -e MySQL-server-5.6.27-1.el6.x86_64
6. [root@localhost mysql]# rpm -e MySQL-client-5.6.27-1.el6.x86_64
7. [root@localhost mysql]# rpm -e MySQL-devel-5.6.27-1.el6.x86_64
8. [root@localhost rc.d]# cd /var/lib/
9. [root@localhost lib]# rm -rf mysql/

註:刪除MySQL數據庫目錄(關鍵) ，否則password不更新（默認安裝，如果自定義安裝路徑和鏈接路徑ln -s ……請刪除。） rm -rf /var/lib/mysql 卸載3： [plain] view plain copy

1. [root@localhost usr]# whereis mysql
2. mysql: /usr/lib64/mysql
3. [root@localhost usr]# rm -rf /usr/lib64/mysql

註：find / -name mysql 註：清空相關mysql的所有目錄以及文件和其他配置和設置等。如果有，則刪除。也必須考慮其他軟件不去影響。 rm -rf /usr/lib/mysql
rm -rf /usr/share/mysql
卸載4： [plain] view plain copy

1. [root@localhost usr]# rm –rf /usr/my.cnf
2. [root@localhost usr]# rm -rf /root/.mysql_sercret

卸載5（自啟服務）： [plain] view plain copy

1. [root@localhost usr]# chkconfig --list | grep -i mysql
2. [root@localhost usr]# chkconfig --del mysqld

[plain] view plain copy

1. 此處刪除看自己設置:mysql/mysqld

mysql完全卸載
