Linux（三十一）centos 7 mysql远程登录权限

标签：

安装好mysql or mariadb后就使用界面管理工具进行管理了，推荐管理工具：SQLyog 、 Navicat for MySQL

1、防火墙要开放3306端口

2、对远程用户授权

[root@localhost backup]# mysql -u root -p
Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 6
Server version: 5.5.41-MariaDB MariaDB Server

Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.

MariaDB [(none)]> show databases;
+--------------------+

MariaDB [(none)]> grant all privileges on *.* to ‘TQ‘@‘192.168.85.1‘ identified by ‘密码‘;

MariaDB [(none)]> grant all privileges on *.* to ‘root‘@‘192.168.85.1‘ identified by ‘密码‘;
Query OK, 0 rows affected (0.03 sec)

3、远程工具连接

4、取消对远程用户的授权

MariaDB [(none)]> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

MariaDB [mysql]> revoke all privileges on *.* from TQ@192.168.85.1;
Query OK, 0 rows affected (0.00 sec)

MariaDB [mysql]> delete from user where user=‘TQ‘;//记住删除用户，否则可以连接
Query OK, 1 row affected (0.03 sec)

MariaDB [mysql]> flush privileges;//更新权限表
Query OK, 0 rows affected (0.03 sec)
