許多時候當(dāng)要使用MySQL時,會遇到如下情況:

1. 信息比較重要,希望通信被加密。
2. 一些端口,比如3306端口,被路由器禁用。
對第一個問題的一個比較直接的解決辦法就是更改mysql的代碼,或者是使用一些證書,不過這種辦法顯然不是很簡單。

這里要介紹另外一種方法,就是利用SSH通道來連接遠(yuǎn)程的Mysql,方法相當(dāng)簡單。
一、建立SSH通道
只需要在本地鍵入如下命令:
ssh -fNg -L 3307:127.0.0.1:3306 myuser@remotehost.com The command tells ssh to log in to remotehost.com as myuser, go into the background (-f) and not execute any remote command (-N), and set up port-forwarding (-L localport:localhost:remoteport ). In this case, we forward port 3307 on localhost to port 3306 on remotehost.com.
二、連接Mysql
現(xiàn)在,你就可以通過本地連接遠(yuǎn)程的數(shù)據(jù)庫了,就像訪問本地的數(shù)據(jù)庫一樣。
mysql -h 127.0.0.1 -P 3307 -u dbuser -p db The command tells the local MySQL client to connect to localhost port 3307 (which is forwarded via ssh to remotehost.com:3306). The exchange of data between client and server is now sent over the encrypted ssh connection.
或者用Mysql Query Brower來訪問Client的3307端口。
類似的,用PHP訪問:
Making It A Daemon A quick and dirty way to make sure the connection runs on startup and respawns on failure is to add it to /etc/inittab and have the init process (the, uh, kernel) keep it going. Add the following to /etc/inittab on each client: sm:345:respawn:/usr/bin/ssh -Ng -L 3307:127.0.0.1:3306 myuser@remotehost.com And that should be all you need to do. Send init the HUP signal ( kill -HUP 1 ) to make it reload the configuration. To turn it off, comment out the line and HUP init again.
