bash脚本在ssh之后执行命令 [英] bash script execute commands after ssh

问题描述

我试图通过我的第一个脚本执行一些命令，但是它不起作用.

I am trying to execute a few commands via my first script but it's not working.

#!/bin/bash

#connect to server
echo "Connecting to the server..."

ssh -t root@IP '

    #switch user to deploy
    su - deploy

    #switch path
    echo "Switching the path"
    cd /var/www/deploys/bin/app/config

    #run deploy script
    echo "Running deploy script"

    /usr/local/bin/cap -S env=prod deploy

    #restart apache
    sudo /bin/systemctl restart  httpd.service

    bash -l
'

发生了什么事?我已成功连接到服务器，更改了用户，然后我什么也没看到.当我像在终端中一样按ctrl + c时，应该执行的命令的一些输出出现了，但是有一些错误.

What is happening? I am successfully connected to the server, the user is changed and then I don't see nothing happening. When I press ctrl + c just like that in terminal, some output from the command that should be executed appears but there are some errors.

为什么启动脚本后我看不到终端中发生的一切?我做错了吗?

Why I don't see everything what is happening in terminal after launching the script? Am I doing it the wrong way?

顺便说一句:当我尝试手动连接并自己运行命令时，一切运行正常.

BTW: when I try connect manually and run the commands myself, everything is working nicely.

使用CentOS 7.

推荐答案

通过ssh登录并执行一组命令的简单方法是

Clean way to login through ssh and excecute a set of commands is

ssh user@ip << EOF
   #some commands
EOF

此处EOF用作命令列表的定界符

here EOF acts as the delimitter for the command list

脚本可以修改为

ssh -t root@IP << EOF

    #switch user to deploy
    su - deploy

    #switch path
    echo "Switching the path"
    cd /var/www/deploys/bin/app/config

    #run deploy script
    echo "Running deploy script"

    /usr/local/bin/cap -S env=prod deploy

    #restart apache
    sudo /bin/systemctl restart  httpd.service

    bash -l
EOF

将执行该命令并在此之后关闭连接

will excecutes the command and closes the connection there after
