centos7 | 删除mysql

1.查看mysql安装

rpm -qa|grep -i mysql

[root@slave3 hadoop]# rpm -qa|grep -i mysql
mysql-community-libs-5.7.27-1.el7.x86_64
mysql-community-common-5.7.27-1.el7.x86_64
mysql-community-client-5.7.27-1.el7.x86_64
mysql57-community-release-el7-8.noarch
perl-DBD-MySQL-4.023-6.el7.x86_64
mysql-community-libs-compat-5.7.27-1.el7.x86_64
php-mysqlnd-7.1.32-1.el7.remi.x86_64
mysql-community-server-5.7.27-1.el7.x86_64

2.卸载前关闭mysql服务

rpm -ev --nodeps mysql57-community-release-el7-8.noarch
rpm -ev --nodeps mysql-community-common-5.7.27-1.el7.x86_64
rpm -ev --nodeps mysql-community-client-5.7.27-1.el7.x86_64
rpm -ev --nodeps mysql-community-libs-5.7.27-1.el7.x86_64
rpm -ev --nodeps mysql-community-server-5.7.27-1.el7.x86_64
rpm -ev --nodeps mysql-community-libs-compat-5.7.27-1.el7.x86_64
rpm -ev --nodeps perl-DBD-MySQL-4.023-6.el7.x86_64
rpm -ev --nodeps php-mysqlnd-7.1.32-1.el7.remi.x86_64

也可以

systemctl stop mysqld

用yum remove mysql-*删除

执行完命令之后再次执行 rpm-qa|grep -i mysql 会发现已经卸载完成。

3.卸载并不会自动删除配置文件等，所以我们还需要手动来删除

find / -name mysql

rm -rf /var/lib/mysql     //将上边的文件全部删除
