pexpect通过ssh执行远程命令

via 小鱼笔记 by smallfish on 12/14/09

pexpect是python一个模块，可以通过：easy_install pexpect 来安装。

这里主要是用pexpect执行ssh，查看远程uptime和df -h看硬盘状况。

#ssh_cmd.py #coding:utf-8 import pexpect  def ssh_cmd(ip, user, passwd, cmd):     ssh = pexpect.spawn('ssh %s@%s "%s"' % (user, ip, cmd))     r = ''     try:         i = ssh.expect(['password: ', 'continue connecting (yes/no)?'])         if i == 0 :             ssh.sendline(passwd)         elif i == 1:             ssh.sendline('yes')     except pexpect.EOF:         ssh.close()     else:         r = ssh.read()         ssh.expect(pexpect.EOF)         ssh.close()     return r  hosts = ''' 192.168.0.12:smallfish:1234:df -h,uptime 192.168.0.13:smallfish:1234:df -h,uptime '''  for host in hosts.split("\n"):     if host:         ip, user, passwd, cmds = host.split(":")         for cmd in cmds.split(","):             print "-- %s run:%s --" % (ip, cmd)             print ssh_cmd(ip, user, passwd, cmd)

hosts数组格式是：主机IP:用户名:密码:命令 (多个命令用逗号, 隔开)
可以看出打印出相应的结果了，可以拼成html发送mail看起来比较美观些咯！
