python--------------paramiko远程控制模块学习（批量执行linux机器多条命令）
import paramiko
def sshExeCMD():
ssh_client=paramiko.SSHClient()
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh_client.connect(hostname="192.168.8.200",port=22,username="root",password="123")
stdin,stdout,stderr = ssh_client.exec_command("cat /etc/redhat-release;hostname;ls /")
print(str(stdout.read()))
ssh_client.close()
if __name__ == '__main__':
sshExeCMD()
=======================================================================================================================
另外一种写法：
# coding=utf-8
import paramiko
# 创建SSH对象
ssh = paramiko.SSHClient()
# 允许连接不在know_hosts文件中的主机
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
# 连接服务器
ssh.connect(hostname='192.168.8.200', port=22, username='root', password='123')
# 执行命令 exec_command('ls')
stdin, stdout, stderr = ssh.exec_command("cat ssh.sh")
# 获取命令结果
result = stdout.read()
print(result)
实现效果：
/var/log/secure日志记录
var
密码的坑：
第二种情况：
关机状态：
显示：TimeoutError: [WinError 10060] 由于连接方在一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。
第三种情况：/etc/ssh/sshd_config限制了root登陆

多个机器批量执行linux命令：：
# 此脚本用于在多个机器上批量执行一个命令
import paramiko
# 用于执行远程命令
def exec_remote_cmd(cmd,hostname="",username="root",passwd="123",port="22"):
# 创建一个ssh对象
ssh_client=paramiko.SSHClient()
# 如果是第一次通过ip连接，会出现yes或者no，可以解决此问题
ssh_client.set_missing_host_key_policy(paramiko.AutoAddPolicy)
ssh_client.connect(hostname=hostname,port=22,username=username,password=passwd)
stdin,stdout,stderr=ssh_client.exec_command(cmd)
print(stdout.read().decode('utf-8'))
ssh_client.close()
# exec_remote_cmd('free -h','192.168.204.128','root','redhat','22')
with open(file="C:/Users/Administrator/Desktop/host.txt")as f:
for line in f:
line=line.strip()
hostname,username,password,port=line.split(',')
# print(line.split(','))
print(hostname + " cmd result:###############################")
exec_remote_cmd('df -h;hostname;cat /etc/redhat-release;systemctl status mysqld;netstat -ntulp',hostname,username,password,port)
在写好python之后，还要准备在桌面上准备个文件
