如何从本地计算机上mysqldump远程数据库 [英] how to mysqldump remote db from local machine

问题描述

我需要在远程服务器上执行数据库的mysqldump，但该服务器未安装mysqldump.我想使用机器上的mysqldump连接到远程数据库并在机器上进行转储.

I need to do a mysqldump of a database on a remote server, but the server does not have mysqldump installed. I would like to use the mysqldump on my machine to connect to the remote database and do the dump on my machine.

我试图创建一个ssh隧道，然后进行转储，但这似乎不起作用.我试过了:

I have tried to create an ssh tunnel and then do the dump, but this does not seem to work. I tried:

ssh -f -L3310:remote.server:3306 [e-mail] -N

成功创建隧道.如果我这样做

The tunnel is created with success. If I do

telnet localhost 3310

我得到一些显示正确服务器mysql版本的内容.但是，执行以下操作似乎尝试在本地连接

I get some blurb which shows the correct server mysql version. However, doing the following seems to try to connect locally

mysqldump -P 3310 -h localhost -u mysql_user -p database_name table_name

推荐答案

正如我在serverfault上尚未看到的那样，答案很简单:

As I haven't seen it at serverfault yet, and the answer is quite simple:

更改:

ssh -f -L3310:remote.server:3306 [e-mail] -N

收件人:

ssh -f -L3310:localhost:3306 [e-mail] -N

然后更改:

mysqldump -P 3310 -h localhost -u mysql_user -p database_name table_name

收件人:

mysqldump -P 3310 -h 127.0.0.1 -u mysql_user -p database_name table_name

(不要使用localhost，这是可能是通过套接字而不是通过端口连接的这些特殊含义"废话之一)

(do not use localhost, it's one of these 'special meaning' nonsense that probably connects by socket rather then by port)

编辑:好，要详细说明:如果将主机设置为localhost，则假定已配置(或默认)--socket选项.请参阅手册，其中将查找/使用选项文件.在Windows下，这可以是命名管道.

edit: well, to elaborate: if host is set to localhost, a configured (or default) --socket option is assumed. See the manual for which option files are sought / used. Under Windows, this can be a named pipe.
