python ssh 执行shell命令

# -*- coding: utf-8 -*-

import paramiko import threading def run(host_ip, username, password, command): ssh = paramiko.SSHClient() try: ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(host_ip, 22, username, password) print('===================exec on [%s]=====================' % host_ip) stdin, stdout, stderr = ssh.exec_command(command, timeout=300) out = stdout.readlines()  for o in out: print (o.strip('\n')) except Exception as ex: print('error, host is [%s], msg is [%s]' % (host_ip, ex.message)) finally: ssh.close() if __name__ == '__main__': # 将需要批量执行命令的host ip地址填到这里
    # eg: host_ip_list = ['IP1', 'IP2']
 host_ip_list = ['147.116.20.19'] for _host_ip in host_ip_list: # 用户名，密码，执行的命令填到这里
        run(_host_ip, 'tzgame', 'tzgame@1234', 'df -h') run(_host_ip, 'tzgame', 'tzgame@1234', 'ping -c 5 220.181.38.148')

 

pycrypto，由于 paramiko 模块内部依赖pycrypto，所以先下载安装pycrypto pip3 install pycrypto pip3 install paramiko （1）基于用户名和密码的连接 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='c1.salt.com', port=22, username='GSuser', password='123') # 执行命令
stdin, stdout, stderr = ssh.exec_command('ls') # 获取命令结果
result = stdout.read() # 关闭连接
ssh.close() （2）基于公钥秘钥连接 import paramiko private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa')
 # 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='c1.salt.com', port=22, username='wupeiqi', key=private_key)
 # 执行命令
stdin, stdout, stderr = ssh.exec_command('df')
 # 获取命令结果
result = stdout.read()
 # 关闭连接
ssh.close() SFTPClient: 　　用于连接远程服务器并进行上传下载功能。 （1）基于用户名密码上传下载 import paramiko transport = paramiko.Transport(('hostname',22)) transport.connect(username='GSuser',password='123') sftp = paramiko.SFTPClient.from_transport(transport)
 # 将location.py 上传至服务器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
 # 将remove_path 下载到本地 local_path
sftp.get('remove_path', 'local_path') transport.close() （2）基于公钥秘钥上传下载 import paramiko private_key = paramiko.RSAKey.from_private_key_file('/home/auto/.ssh/id_rsa') transport = paramiko.Transport(('hostname', 22)) transport.connect(username='GSuser', pkey=private_key ) sftp = paramiko.SFTPClient.from_transport(transport)
 # 将location.py 上传至服务器 /tmp/test.py
sftp.put('/tmp/location.py', '/tmp/test.py')
 # 将remove_path 下载到本地 local_path
sftp.get('remove_path', 'local_path') transport.close()

 

 

 

 

 

 

 

下面是多线程执行版本

#!/usr/bin/python #coding:utf-8
import threading import subprocess import os import sys sshport = 13131 log_path = 'update_log' output = {} def execute(s, ip, cmd, log_path_today): with s: cmd = '''ssh -p%s root@%s -n "%s" ''' % (sshport, ip, cmd) ret = subprocess.Popen(cmd, shell=True, stdout=subprocess.PIPE, stderr=subprocess.STDOUT) output[ip] = ret.stdout.readlines() if __name__ == "__main__": if len(sys.argv) != 3: print "Usage: %s config.ini cmd" % sys.argv[0] sys.exit(1) if not os.path.isfile(sys.argv[1]): print "Usage: %s is not file!" % sys.argv[1] sys.exit(1) cmd = sys.argv[2] f = open(sys.argv[1],'r') list = f.readlines() f.close() today = datetime.date.today() log_path_today = '%s/%s' % (log_path,today) if not os.path.isdir(log_path_today): os.makedirs(log_path_today) threading_num = 100
    if threading_num > len(list): threading_num = len(list) s = threading.Semaphore(threading_num) for line in list: ip = line.strip() t = threading.Thread(target=execute,args=(s, ip,cmd,log_path_today)) t.setDaemon(True) t.start() main_thread = threading.currentThread() for t in threading.enumerate(): if t is main_thread: continue t.join() for ip,result in output.items(): print "%s: " % ip for line in result: print " %s" % line.strip() print "Done!"

 

以上脚本读取两个参数，第一个为存放IP的文本，第二个为shell命令

执行效果如下
