SSH到远程计算机并使用Python以root用户身份编辑文件

Question

I am working on a Python script that can SSH into multiple remote CentOS machines and change the value of 'ONBOOT' from 'yes' to 'no' in '/etc/sysconfig/network-scripts/ifcfg-eth1'. I can SSH into remote machines using Paramiko with my user credentials. In order to edit the '/etc/sysconfig/network-scripts/ifcfg-eth1' file I have to become a sudo user and then only I can edit the file. The Problem I am facing with my script is I cannot login directly as a root user into CentOS. I should first login with my user credentials and Then change to root using 'sudo -s' and password. Is there any way to ssh into the remote machine with my user credentials and change to root user and edit the file.?

Answer 1

First, make a connection using ssh.connect of paramiko and then

   import paramiko
   ssh = paramiko.SSHClient()
   ssh.connect("hostname", username = "username", password = "password")
   cmd = "echo {} | sudo -S {}".format("password", "touch /opt/giri")
   ssh.exec_command(cmd)

The logined user is a normal user with sudo permission. So first the script logins as "normal user" and then executes the command with sudo permission.

-S option of the sudo command to make sudo get the its from stdinread the password from the standard input instead of using the terminal device.
