#################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]#
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 /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
