mysql账户添加远程访问

我们要将root账户设置为远程可访问

mysql> show databases;
+--------------------+
| Database           |
+--------------------+
| here               |
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+

选择mysql数据库

mysql> 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

mysql> update user set Host = '%' where User='root';
Query OK, 1 row affected (0.13 sec)
Rows matched: 1  Changed: 1  Warnings: 0

最后要刷新一下执行这个

mysql> flush privileges;
Query OK, 0 rows affected (0.01 sec)

然后就可以了
