本文记录了CentOS下MySQL的彻底卸载,供大家参考,具体内容如下:
1、查看MySQL是否安装
方式1:
1 2 3 4 5 6 7 8 9 10 11 | [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 :不区分大小写):
1 2 3 4 5 | [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、卸载MySQL
卸载1:
1 2 3 | [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 |
如果装了mysql-devel(其他一样add command),卸载为:
1 2 3 4 5 6 7 | [root@Tony_ts_tian init.d] # yum remove mysql mysql-devel mysql-server mysql-libs compat-mysql51<br> 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 |
卸载2 {继续,1,2选择一种(此处为介绍):}:
1 2 3 4 5 6 7 8 9 | [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:删除MySQL数据库目录(关键) ,否则password不更新(默认安装,如果自定义安装路径和链接路径ln -s ……请删除。)
1 | rm -rf /var/lib/mysql |
卸载3:
1 2 3 | [root@localhost usr] # whereis mysql mysql: /usr/lib64/mysql [root@localhost usr] # rm -rf /usr/lib64/mysql |
注:find / -name mysql
注:清空相关mysql的所有目录以及文件和其他配置和设置等。如果有,则删除。也必须考虑其他软件不去影响。
1 2 | rm -rf /usr/lib/mysql rm -rf /usr/share/mysql |
卸载4:
1 2 | [root@localhost usr] # rm –rf /usr/my.cnf [root@localhost usr] # rm -rf /root/.mysql_sercret |
卸载5(自启服务):
1 2 | [root@localhost usr] # chkconfig --list | grep -i mysql [root@localhost usr] # chkconfig --del mysqld |
此处删除看自己设置:mysql/mysqld
