1、安装库
pip install paramiko

2、函数介绍
导入库
import paramiko

创建客户端
ssh = paramiko.SSHClient()

设置校验
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

连接登录
ssh.connect(‘192.168.xx.xx’, 22, ‘root’, ‘pwd’)

执行命令
stdin, stdout, stderr = ssh.exec_command(‘pwd’)

读取结果打印
str1 = stdout.read().decode(‘utf-8’)
print(str1)

关闭ssh客户端
ssh.close()

3、代码编写

import paramikossh = paramiko.SSHClient()def ssh_login(ip, port, username, passwd):global sshssh = paramiko.SSHClient()ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())ssh.connect(ip, port, username, passwd)returndef ssh_exe_cmd(cmd):global sshstdin, stdout, stderr = ssh.exec_command(cmd)str1 = stdout.read().decode('utf-8')print(str1)returndef main():ssh_login('192.168.73.176', 22, 'z', 'z')ssh_exe_cmd('pwd')ssh_exe_cmd('ifconfig')ssh.close()returnmain()

4、执行结果

5、项目实战
需求：
测试远程主机ssh能登录多少ssh

import paramiko
import timedef ssh_login(ip, port, username, passwd):ssh = paramiko.SSHClient()ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())ssh.connect(ip, port, username, passwd)returndef test_ssh_login():i = 0while(1):i = i + 1print("登录个数：", i)ssh_login('192.168.73.176', 22, 'z', 'z')#time.sleep(0.01)def main():test_ssh_login()returnmain()
