我的程序使用远程MySQL服务器,我想在我的计算机上创建一个本地代理服务器,以便使操作更快(池连接、缓存查询等)。我参考了文档:http://dev.mysql.com/doc/refman/5.1/en/mysql-proxy.html
我在一个控制台上运行:
erelsgl@ubuntu:~$ mysql-proxy --proxy-backend-addresses=$MYSQL --log-level=debug2011-11-22 09:43:30: (message) mysql-proxy 0.8.2 started
2011-11-22 09:43:30: (debug) max open file-descriptors = 1024
2011-11-22 09:43:30: (message) proxy listening on port :4040
2011-11-22 09:43:30: (message) added read/write backend: qa-srv:3308在另一个控制台上:
erelsgl@ubuntu:~$ mysql --user root --host=localhost --port=4040
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 81
Server version: 5.1.41-3ubuntu12.10 (Ubuntu)
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
mysql> show databases;但是,我看到的不是远程服务器(qa-srv)上的数据库,而是本地服务器上的数据库!
我还尝试了这个:
erelsgl@ubuntu:~$ mysql --user root --host=qa-srv --port=4040
ERROR 2003 (HY000): Can't connect to MySQL server on 'qa-srv' (111)我还尝试运行代理,而不是mysql守护进程:
erelsgl@ubuntu:~$ sudo service mysql stop
mysql stop/waiting
erelsgl@ubuntu:~$ mysql-proxy --proxy-backend-addresses=$MYSQL --log-level=debug --proxy-address=0.0.0.0:3306
2011-11-22 14:14:25: (message) mysql-proxy 0.8.2 started

2011-11-22 14:14:25: (message) proxy listening on port 0.0.0.0:3306
2011-11-22 14:14:25: (message) added read/write backend: qa-srv:3308在另一个控制台上:
erelsgl@ubuntu:~$ mysql --user root
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)如何告诉我的mysql客户端通过本地代理连接到远程服务器?

万岁!我找到了解决方案。
在控制台A上:
erelsgl@ubuntu:~$ mysql-proxy --proxy-backend-addresses=qa-srv:3308 --log-level=debug --proxy-address=127.0.0.1:3306
2011-11-22 18:55:02: (message) mysql-proxy 0.8.2 started
2011-11-22 18:55:02: (debug) max open file-descriptors = 1024
2011-11-22 18:55:02: (message) proxy listening on port 127.0.0.1:3306
2011-11-22 18:55:02: (message) added read/write backend: qa-srv:3308在控制台B上:
erelsgl@ubuntu:~$ mysql -u <username-on-remote-database> -h 127.0.0.1或者,如果您仍然希望本地数据库处于活动状态:
在控制台A上:
erelsgl@ubuntu:~$ mysql-proxy --proxy-backend-addresses=qa-srv:3308 --log-level=debug
