设置Ubuntu允许远程连接MySQL
2011-07-19 09:55 ☆冷枫☆ 阅读(3698) 评论(0) 编辑 收藏 举报 出于安全方面考虑MySql-Server 只允许本机(localhost, 127.0.0.1)来连接访问. 这对于 Web-Server 与 MySql-Server 都在同一台服务器上的网站架构来说是没有问题的. 但随着网站流量的增加, 后期服务器架构可能会将 Web-Server 与 MySql-Server 分别放在独立的服务器上, 以便得到更大性能的提升, 此时 MySql-Server 就要修改成允许 Web-Server 进行远程连接.
假设我们有:
假设我们有:
Client: 192.168.1.100 //win7 OR XP
Mysql-Server : 192.168.1.101 //ubuntu
我们可以按照下面的步骤修改:
1、 登录 Mysql-Server 连接本地 mysql (默认只允许本地连接)
01 Microsoft Windows XP [版本 5.1.2600]
02 (C) 版权所有 1985-2001 Microsoft Corp.
03
04 C:\Documents and Settings\kuco>mysql -h localhost -u root -p
05 Enter password:
06 Welcome to the MySQL monitor. Commands end with ; or \g.
07 Your MySQL connection id is 13
08 Server version: 5.1.45-community-log MySQL Community Server (GPL)
09
10 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

2, 修改 Mysql-Server 用户配置
01 mysql> USE mysql; -- 切换到 mysql DB
02 Database changed
03 mysql> SELECT User, Password, Host FROM user; -- 查看现有用户,密码及允许连接的主机
04 +------+----------+-----------+
05 | User | Password | Host |
06 +------+----------+-----------+
07 | root | | localhost |
08 +------+----------+-----------+
09 1 row in set (0.00 sec)
10
11 mysql> -- 只有一个默认的 root 用户, 密码为空, 只允许 localhost 连接
12 mysql> -- 下面我们另外添加一个新的 root 用户, 密码为空, 只允许 192.168.1.100 连接
13 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.100' IDENTIFIED BY '' WITH GRANT OPTION; 或允许所有ip访问:
14
15 mysql> -- 当然我们也可以直接用 UPDATE 更新 root 用户 Host, 但不推荐, SQL如下:
16 mysql> -- UPDATE user SET Host='192.168.1.100' WHERE User='root' AND Host='localhost' LIMIT 1;
02 Database changed
03 mysql> SELECT User, Password, Host FROM user; -- 查看现有用户,密码及允许连接的主机
04 +------+----------+-----------+
05 | User | Password | Host |
06 +------+----------+-----------+
07 | root | | localhost |
08 +------+----------+-----------+
09 1 row in set (0.00 sec)

12 mysql> -- 下面我们另外添加一个新的 root 用户, 密码为空, 只允许 192.168.1.100 连接
13 mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'192.168.1.100' IDENTIFIED BY '' WITH GRANT OPTION; 或允许所有ip访问:
mysql> GRANT ALL PRIVILEGES ON *.* TO root@"%" IDENTIFIED BY "mysqluser";
14
15 mysql> -- 当然我们也可以直接用 UPDATE 更新 root 用户 Host, 但不推荐, SQL如下:
16 mysql> -- UPDATE user SET Host='192.168.1.100' WHERE User='root' AND Host='localhost' LIMIT 1;
3、 修改 Mysql 配置文件 my.ini
1 bind-address = 127.0.0.1
2 将 bind-address = 127.0.0.1 这一行注释掉, 即修改为:
3 #bind-address = 127.0.0.1
4 到此 Mysql-Server 端配置就完成了.
然后重启 MySQL
$> sudo /etc/init.d/mysql restart
* Starting MySQL database server mysqld
...done.
* Checking for corrupt, not cleanly closed and upgrade needing tables.
andy@ubuntu:~$ sudo /etc/init.d/mysql start
* Starting MySQL database server mysqld
...done.

...done.
4, 连接 Web-Server , 检查一下是否能连上
1 kuco@kuco-desktop:/$ /opt/lampp/bin/mysql -h 192.168.1.101 -u root -p
2 Enter password:
3 Welcome to the MySQL monitor. Commands end with ; or \g.
4 Your MySQL connection id is 23
5 Server version: 5.1.45-community-log MySQL Community Server (GPL)
6
7 Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
8
9 mysql> -- 一切OK
2 Enter password:

配置到这一步就可以使用Mysql客户端工具远程链接了。
