在 shell实现hp刀片ilo地址配置 篇中有提到通过python来实现HP管理口的配置,没事写了段python实现的代码。大意也是通过pexpect模块来实现相应的配置,不过这段代码初写的时候是基于paramiko模块获取信息,并找到可用IP的,后面又写了一段通过pexpect实现自动交互输入的。真正的实现的时候并不需要paramiko部分的,不过懒得的代码整合和美化了,凑合着全部堆上来吧。代码如下:
#!/usr/bin/python #-*- coding: utf-8 -*- # code from www.361way.com <itybku@139.com> import re,paramiko import commands def ssh2(ip,username,passwd,cmd): try: ssh = paramiko.SSHClient() ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) ssh.connect(ip,22,username,passwd,timeout=5) stdin,stdout,stderr = ssh.exec_command(cmd) return stdout.readlines() #print x.strip("\n") #print '%s\tOK\n'%(ip) ssh.close() except : print '%s\tError\n'%(ip) def stdoutsplit(stdout,keywords): for line in stdout: if line.find(keywords) != -1: return re.split(r': ',line)[1].strip('\n') def iprange(ip,mask): ipaddr = ip.split('.') netmask = mask.split('.') cidr = sum([bin(int(x)).count('1') for x in netmask]) net_start = [str(int(ipaddr[x]) & int(netmask[x])) for x in range(0,4)] end = int(netmask[3]) + 2**(32-cidr) - 1 firstip = '.'.join(net_start) endip = '.'.join(ipaddr[0:3]) + '.' + str(end) return firstip + '\t' + endip stdout = ssh2("10.105.10.45","admin","password","SHOW OA NETWORK") oaip = stdoutsplit(stdout,'IPv4 Address:') mask = stdoutsplit(stdout,'Netmask:') gate = stdoutsplit(stdout,'Gateway Address:') #print oaip,mask,gate cmd ="fping -g " + iprange(oaip,mask) status, output = commands.getstatusoutput(cmd) print 'Available IP follows:' print '*'*40 for line in output.split('\n'): if line.find('unreachable') != -1: print line print '*'*40 iloip = raw_input("please input the ilo ip: ") bid = raw_input("please input the blade bay id: ") setip="set ebipa server " + iloip + '\t' + mask + '\t' + bid setgate="set ebipa server gateway " + gate + '\t' + bid print setip print setgate #--------------------------------------------------------------------- from pexpect.pxssh import pxssh s = pxssh() s.login('10.105.10.45','admin','password',original_prompt='>',auto_prompt_reset=False) s.sendline("set ebipa server 10.105.10.58 255.255.255.0 13") s.expect('bays\?') s.sendline('YES') #print s.before s.expect('>') print s.before s.logout()
算个半成品吧,需要的功能代码里都有了,想实现shell里的功能,只是简单的修改下就成了。实际代码要不了这么多的,后面重新IP规划,给所有代片全配置上连续的IP,HP管理口本身也有autofill 功能,配置起来也比较快。使用脚本无非是练习下,同时也对管理口增强更多的内部了解。
