一、停止MySQL
[root@localhost /]# service mysqld stop
二、查看当前安装mysql情况,查找以前是否装有mysql
[root@localhost /]# rpm -qa|grep -i mysql mysql-community-client-8.0.13-1.el7.x86_64 mysql-community-libs-8.0.13-1.el7.x86_64 mysql-community-common-8.0.13-1.el7.x86_64 mysql-community-server-8.0.13-1.el7.x86_64
三、执行命令删除安装的MySQL
[root@localhost /]# rpm -ev mysql-community-client-8.0.13-1.el7.x86_64
报错:
error: Failed dependencies:
mysql-community-client(x86-64) >= 8.0.0 is needed by (installed) mysql-community-server-8.0.13-1.el7.x86_64
原因是依赖包错误,再执行以下命令解决:
[root@localhost /]# rpm -ev mysql-community-client-8.0.13-1.el7.x86_64 --nodeps
剩余几个也按照上述操作执行,加上 --nodeps
再执行 # rpm -qa|grep -i mysql 命令,查看是否删除成功。
四:查看之前安装的MySQL的目录并删除
[root@localhost /]# find / -name mysql /var/lib/mysql /var/lib/mysql/mysql /usr/lib64/mysql /usr/share/mysql [root@localhost /]# rm -rf /var/lib/mysql [root@localhost /]# rm -rf /var/lib/mysql/mysql [root@localhost /]# rm -rf /usr/lib64/mysql [root@localhost /]# rm -rf /usr/share/mysql
五:删除my.cnf
卸载后/etc/my.cnf不会删除,需要进行手工删除
[root@localhost /]# rm -rf /etc/my.cnf
最后查看一下是否卸载完毕,无结果说明卸载完成。
[root@localhost /]# rpm -qa|grep -i mysql
