最近在學(xué)習(xí)python，用python寫了個(gè)檢查ssh存活的腳本。寫完后想增加多線程功能，加快效率，可是一直報(bào)錯(cuò)，麻煩大神幫我看下到底錯(cuò)在哪了 以下是代碼： #!/usr/bin/python import os import string import paramiko import traceback import threading class SshServerCMD(): def __init__(self): print 'start' self.username = 'root' self.passwd = '123' self.cmd = 'date +%s' self.ssh = paramiko.SSHClient() self.pass_file = '/opt/scripts/etc/ssh_proxy.conf' self.paramiko_log= '/tmp/check_ssh_proxy.log' self.threads = [] HostList = open(self.pass_file) for line in HostList.readlines(): ARAY_line = string.split(line) self.host = ARAY_line[0] self.port = int(ARAY_line[1]) self.t = threading.Thread(target = self.Connect,args = (self.host,self.port,self.username,self.passwd)) self.threads.append(self.t) for i in range(10): self.threads[i].start() for i in range(10): self.threads[i].join() def Connect(self,host,port,username,passwd): # This function is to connect the agent self.ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) #ssh.load_system_host_keys() paramiko.util.log_to_file(self.paramiko_log) try: self.ssh.connect(host,port,username,passwd) except Exception as e: print '\033[31m' + self.host,str(e) + '\033[0m' else: self.Cmd() self.ssh.close() def Cmd(self): stdin,stdout,stderr = self.ssh.exec_command(self.cmd) self.sout = stdout.readlines() print '\033[32m' + self.host,str(self.sout) + '\033[0m' if __name__ == '__main__': SshServerCMD() 以下是/opt/scripts/etc/ssh_proxy.conf文件內(nèi)容 192.168.1.2 4001 192.168.1.3 4002 192.168.1.4 4003 192.168.1.5 4004 192.168.1.6 4005 192.168.1.7 4006 192.168.1.8 4007 192.168.1.9 4008 192.168.1.10 4009 192.168.1.11 4010 報(bào)錯(cuò)：執(zhí)行腳本后，發(fā)現(xiàn)程序不停在嘗試ssh 192.168.1.11，也就是文本中所寫的最后一行的ip地址，并且全部都是連接失敗。在邏輯上我就想不通，就算是連接失敗，也應(yīng)該從第一行ip開(kāi)始嘗試，為什么會(huì)從最后一行ip開(kāi)始ssh呢？并且一直在嘗試ssh最后一行ip，求指教。
