linux远程执行命令 [英] linux execute command remotely

问题描述

如何在远程Linux上执行命令/脚本？
说我想从框a中的框b上执行服务tomcat启动。

how do I execute command/script on a remote linux box? say I want to do service tomcat start on box b from box a.

推荐答案

是最安全的方式，例如：

I guess ssh is the best secured way for this, for example :

ssh -OPTIONS -p SSH_PORT user@remote_server "remote_command1; remote_command2; remote_script.sh"  

其中OPTIONS必须根据您的特定需求例如，仅绑定到ipv4），您的远程命令可能会启动您的tomcat守护程序。

where the OPTIONS have to be deployed according to your specific needs (for example, binding to ipv4 only) and your remote command could be starting your tomcat daemon.

注意：

如果您不想提示在每个ssh运行，也有一个看看ssh代理，并optionnaly到keychain如果你的系统允许它。密钥是...了解密钥交换过程。仔细查看ssh_config（例如ssh客户端配置）和sshd_config（例如ssh服务器配置）。配置文件名取决于您的系统，无论如何，你会在/ etc / sshd_config中找到它们。

Note:
if you do not want to be prompt at every ssh run, also have a look to ssh-agent, and optionnaly to keychain if your system allows it. Key is... to understand the keys exchange process. Take a careful look to ssh_config (eg ssh client config) and sshd_config (eg ssh server config). Config file names depends on your system, anyway you'll find them somewhere like /etc/sshd_config. Ideally do not run ssh as root obviously but with a dedicated user on both servers.
