python 利用pexpect进行多机

在安装之前，确认你的机器安装了python,和easy_install.通常python是自动安装的，如果没有安装easy_install，那么wget -q http://peak.telecommunity.com/dist/ez_setup.py 获取一下

python ez_setup.py

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)
