Linux下完全卸载mysql

1.查看是否安装mysql

rpm -qa | grep -i mysql 2.关闭mysql服务

service mysql status 查看运行状态 service mysql stop 停止运行 service mysql status 查看运行状态是否停止

3.卸载mysql的相关组件，ev后面的内容就是步骤一所查到的内容

rpm -ev MySQL-devel-5.6.23-1.linux_glibc2.5有时候需要按顺序删除，有时候会报以下错误

error: Failed dependencies: libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64 libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64 这时候就要用下面的办法删除

rpm -e --noscripts *********** 4.收集mysql对应的文件夹信息

find / -name mysql若果有，都要删掉

rm -rf **********还需要删除一个配置文件 my.conf

5.删除mysql用户和用户组

[root@izuf6147skj2ic0e6i0599z ~]# more /etc/passwd | grep mysql mysql:x:27:27:MySQL Server:/var/lib/mysql:/bin/bash [root@izuf6147skj2ic0e6i0599z ~]# find / -name mysql [root@izuf6147skj2ic0e6i0599z ~]# more /etc/shadow | grep mysq mysql:!!:17324:::::: [root@izuf6147skj2ic0e6i0599z ~]# more /etc/group | grep mysql mysql:x:27: [root@izuf6147skj2ic0e6i0599z ~]# userdel mysql [root@izuf6147skj2ic0e6i0599z ~]# groupdel mysql groupdel: group 'mysql' does not exist 6.确认是否删除

rpm -qa | grep -i mysql
