linux下mysql远程访问

Mysql默认root用户只能本地访问，不能远程连接管理mysql数据库，但项目中必须要远程导入导出数据，所以研究了一下。

1 修改localhost
2 配置/etc/mysql/my.cnf
3 其他

1 修改localhost

更改 "mysql" 数据库里的 "user" 表里的 "host" 项，从"localhost"改成"%"

mysql>use mysql;
mysql>update user set host ="%" where user = "root";
mysql>select host, user from user;
mysql>FLUSH PRIVILEGES;

这时的user表应该是这样的

mysql> select * from user;       
+-----------+------------------+-
| Host      | User             | 
+-----------+------------------+-
| %         | root             | 
| debian    | root             | 
| 127.0.0.1 | root             | 
| ::1       | root             | 
| %         |                  | 
| debian    |                  | 
| %         | debian-sys-maint | 
+-----------+------------------+-
7 rows in set (0.00 sec)

2 配置/etc/mysql/my.cnf

查看/etc/mysql/my.cnf中,skip-networking 是否已被注掉 sudo gedit /etc/mysql/my.cnf

原：
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address    = 127.0.0.1
#
改为：
#
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
# bind-address    = 127.0.0.1

1 Mysql的端口是否正确

通过netstat -ntlp查看端口占用情况，一般情况下端口是3306。在用工具连接MySQl是要用到端口。例如My AdminMy Query BrowserMySQl Front等。

2 查看iptables是否停掉,没关的情况下,无法连接

通过：service iptables stop临时关闭报错：ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.51.112' (113)
