linux下mysql遠程訪問

Mysql默認root用戶只能本地訪問，不能遠程連接管理mysql數據庫，但項目中必須要遠程導 入導出數據，所以研究了一下。

Table of Contents

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

1 修改localhost

• 更改 "mysql" 數據庫里的 "user" 表里的 "host" 項，從"localhost"改成"%"

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

• 這時的user表應該是這樣的

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
#
改為：
#
# 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
#

3 其他

1 Mysql的端口是否正確

通過netstat -ntlp查看端口占用情況，一般情況下端口是3306。在用工具連接MySQl是要用 到端口。例如My Admin\My Query Browser\MySQl Front等。

2 查看iptables是否停掉,沒關的情況下,無法連接

通過：service iptables stop臨時關閉 報錯：ERROR 2003 (HY000): Can't connect to MySQL server on '192.168.51.112' (113)
