1.1 invoke_shell()方式

1.1.1 创建client

import paramiko

port = 22
hostName = "admin"
hostPasswd = "Admin"
hostIp = "192.168.0.1"

sshclient = paramiko.SSHClient()
sshclient.set_missing_host_key_policy(paramiko.AutoAddPolicy())
sshclient.connect(hostIp, port, hostName, hostPasswd)
#or
sshclient.connect(hostIp, port, hostName, hostPasswd, compress=True)

#激活连接host的terminal
channel = sshclient.invoke_shell()

1.1.2 发送命令

channel.send("su")
channel.send("rootPwd")
channel.send("cd /bin")
channel.send("ls")
binRes = channel.recv(9999).decode('utf-8')
if "python" not in binRes:
    print("not find python, exit!!")
    exit(1)
else:
    print("the linx have python,continue")
channel.send("cd /home/admin/softScript")
channel.send("python script.py")

sshclient.close()

另外一种执行命令的方式是：exec_command

1.2 exec_command方式

1.2.1 创建client

import paramiko

port = 22
hostName = "admin"
hostPasswd = "Admin"
hostIp = "192.168.0.1"

sshclient = paramiko.SSHClient()
sshclient.set_missing_host_key_policy(paramiko.AutoAddPolicy())
sshclient.connect(hostIp, port, hostName, hostPasswd)
#or
sshclient.connect(hostIp, port, hostName, hostPasswd, timeout = 10)

1.2.2 发送命令

stdin, stdout, stderr = sshclient.exec_command("python /home/admin/test.py")
stdin.readlines()
stdout.readlines()
stderr.readlines()
