SSH到Linux主机和须藤以root用户

问题描述：

这里是代码片段我曾经SSH和运行命令作为我的用户。当我尝试使用sudo命令我得到有关TTY的错误 - 不是终端（类似的东西）

sshProcess = subprocess.Popen(['ssh', hostname], stdin=subprocess.PIPE, stdout = subprocess.PIPE, universal_newlines=True, bufsize=0) 
sshProcess.stdin.write("hostname\n") 
sshProcess.stdin.write("ls -ldr %s \n"%path) 
sshProcess.stdin.write("pwd \n") 
sshProcess.stdin.close() 
for line in sshProcess.stdout: 
if line == "END\n": 
break 
print(line,end="")

，但我不能够低于命令运行

sshProcess.stdin.write("sudo su - serviceuser \n")

答

可以强制通过指定-t选项来进行伪tty分配。

subprocess.Popen(['ssh -t', hostname], .....

从man ssh

-t  
Force pseudo-tty allocation. This can be used to execute arbitrary screen-based programs on a remote machine, which can be very useful, e.g. when implementing menu services. Multiple -t optionsforce tty allocation, even if ssh has no local tty.

我尝试了以前，但没有奏效我得到以下错误回溯（最近最后一次通话）：文件 “ssh.py”，行11， sshProcess = subprocess.Popen（['ssh -t'，hostname]，stdin = subprocess.PIPE，stdout = subprocess.PIPE，universal_newlines = True，bufsize = 0）文件“/ usr/lib/python2 .7/subprocess.py“，l INE 711，在__init__ errread，ERRWRITE）文件 “/usr/lib/python2.7/subprocess.py”，线1343，在_execute_child 加注child_exception OSERROR：[错误2]没有这样的文件或目录 – Springhills

我加shell = True在Popen中，但我得到了其他错误 sshProcess = subprocess.Popen（['ssh -t'，hostname]，shell = True，stdin = subprocess.PIPE，stdout = subprocess.PIPE，universal_newlines = True，bufsize = 0） – Springhills
