如何从PHP执行远程bash脚本

Question

I need to execute a bash script on a remote web server from PHP . The request originates from web1 via PHP and needs to execute a bash script on another web server web2 . web1 can SSH into web2 all local traffic, but doing SSH via PHP is really nasty, and running exec("ssh user@web2.mydomain.com ./bash_script") seems like a terrible idea for security. Also, trying to expose some sort of HTTP interface from a bash script seems like the wrong approach.

What is recommended? Are there any cross language and remote execution libraries or frameworks?

Thinking I could write a simple wrapper in Node.js that executes the bash script and lives on web2 . web1 simply hits the node.js wrapper over HTTP.

Thanks.

You could use rexec command for this. rexec will help you to execute a remote command.

rexec [ -abcdhns -l username -p password ] host command
