针对前面的代码 http://lxsym.blog.51cto.com/1364623/1065854，还存在的问题进行了改善:
1、去掉明文密码，通过交互输入密码
2、通过传参执行相关命令,增加灵活性
3、异常处理
4、其他问题待发现，联系QQ群: 24967504
具体代码：
#!/usr/bin/env python
#-*- coding: utf-8 -*-
import sys
import paramiko
import threading
import getpass
def main():
try:
cmd = sys.argv[1:]
username = "root"
passwd = getpass.getpass('Please input password: ')
threads = [4]
f = file('list.txt')
while True:
ip = f.readline()
if len(ip) == 0:
break
a = threading.Thread(target=ssh2,args=(ip,username,passwd,cmd))
a.start()
f.close()
except:
pass
def ssh2(ip,username,passwd,cmd):
try:
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(ip,22,username,passwd,timeout=5)
for m in cmd:
stdin,stdout,stderr = ssh.exec_command(m)
stdin.write("Y")
out = stdout.readlines()
for o in out:
print o,
print '[OK]%s' %(ip),
print '========================================================================='
ssh.close()
except:
print '[Error]%s' %(ip),
print '========================================================================='
if __name__ == '__main__':
main()
执行结果：
[root@bw-vm-soft test]# python ssh2.py 'md5sum /usr/local/webserver/nginx/conf/nginx.conf'
Please input password:
