python,pexpect登录ssh并
1、 安装python的Pexpect模块
wget http://jaist.dl.sourceforge.net/project/pexpect/pexpect/Release%202.3/pexpect-2.3.tar.gz
tar xzf pexpect-2.3.tar.gz
cd pexpect-2.3
python setup.py install
2、 执行脚本
可以登录到机器执行一些简单的命令等。。
#!/usr/bin/env python # -*- coding: utf-8 -*- import pexpect from getpass import getpass passwd = getpass() def ssh_cmd(user,ip, cmd): ??????? ssh = pexpect.spawn('ssh %s@%s "%s"' % (user,ip,cmd)) ??????? try: ??????????????? i = ssh.expect(['password:', 'continue connecting (yes/no)?'], timeout=5) ??????????????? if i == 0 : ??????????????????????? ssh.sendline(passwd) ??????????????? elif i == 1: ??????????????????????? ssh.sendline('yes') ??????????????????????? ssh.expect('password: ') ??????????????????????? ssh.sendline(passwd) ??????? except pexpect.EOF: ??????????????? print "EOF" ??????? except pexpect.TIMEOUT: ??????????????? print "TIMEOUT" ??????? else: ??????????????? r = ssh.read() ??????????????? print r ??????? ssh.close()
if __name__ == '__main__': ??????? file=open("/root/python/filelist",'r') ??????? a = file.read() ??????? file.close() ??????? for host in a.split("\n"): ??????????????? if host: ??????????????????????? user,ip,cmd = host.split("::") ??????????????????????? print "-- %s run:%s --" % (ip, cmd) ??????????????????????? ssh_cmd(user,ip,cmd)
more /root/python/filelist
