    aptitude reinstall mysql-server
    
    sudo mysql_secure_installation

    vim /etc/mysql/mysql.conf.d/mysqld.cnf

    注释掉bind-address  = 127.0.0.1

    SHOW VARIABLES LIKE 'validate_password%';
    set global validate_password_length=4;
    set global validate_password_policy=0;
    grant all on *.* to root@'%' identified by '12345' with grant option; #允许任何ip地址(%表示允许任何ip地址)的电脑用admin帐户和密码(123456)来访问这个mysql server。

    flush privileges; #刷新权限表,使配置生效

    systemctl restart mysql

     修改ip

    修改客户端ubuntu desktop的eth0的IP地址:

         ifconfig  eth0  192.168.1.100  netmask  255.255.255.0

         再看一下是否被修改

         ifconfig  -a

    11.  使修改后的IP地址生效:

        ifconfig  eth0  up

        互相ping   仍然可以ping通
