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)
复制代码
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! |
