最近在學習python,感受很不錯,特別是實現批量/併發處理。實現起來很是方便,比shell方便不少。剛學python一個月,在這留個記錄。下面分享一段代碼。多提建議/意見~(QQ×××流:24967504)python
需求:批量查看/對比線上服務器的狀態狀況,如uptime、df -h、MD5sum文件等等。本打算讓執行命令經過傳參進行、密碼經過交互輸入(3次不對退出)。後面再完善~~shell
#-*- coding: utf-8 -*-
#!/usr/bin/python服務器
import paramiko
import threading
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 '========================================================================='
def main():
cmd = ['uptime'] #執行命令
username = "root"
passwd = "密碼"
threads = [4]
f = file('list.txt') #ip列表
while True:
ip = f.readline()
if len(ip) == 0:
break
a = threading.Thread(target=ssh2,args=(ip,username,passwd,cmd))
a.start()
f.close() 併發
if __name__ == '__main__':
main()ssh
執行結果:ide
