#设置远程访问
#root是允许远程访问的账户名(可以是其他的),"192.168.7.200"表示只允许这个ip地址远程访问(任意地址:‘%’),‘123456’是远程访问密码
#完整意思:允许用户root在ip为192.168.7.200的主机上使用密码123456来登录mysql
mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.7.200' IDENTIFIED BY '123456' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
#移除远程访问
mysql> REVOKE ALL PRIVILEGES ON *.* FROM 'root'@'192.168.7.200';#移除授权
#下面是删除之前设置的远程登录信息(user,ip,password)
mysql> use mysql;
mysql> select host,user from user where user='root';
mysql> delete from user where user='root' and host='192.168.7.200';
mysql> flush privileges;
mysql> select host,user from user where user='root';#可以看到已经删除了
