服务器运维常用的python模块概述
最近开始复习python的使用,把服务器运维常用的模块的用法进行了实例化概述。
==========sort========================= python 排序; ls=[1,31,13,141,41] ls.sort() print ls 元组sort: >>> lst=[(‘wyl‘,24),(‘hjj‘,25),(‘zs‘,22),(‘lisi‘,14)] >>> sorted(lst,key=lambda lst:lst[1],reverse=True) [(‘hjj‘, 25), (‘wyl‘, 24), (‘zs‘, 22), (‘lisi‘, 14)] 字典排序: >>> print d {‘a‘: 2, ‘e‘: 221, ‘d‘: 222, ‘f‘: 22, ‘age‘: 24, ‘name‘: ‘wyl‘} >>> sorted(d.iteritems(),key= lambda d:d[1]) [(‘a‘, 2), (‘f‘, 22), (‘age‘, 24), (‘e‘, 221), (‘d‘, 222), (‘name‘, ‘wyl‘)] ==========paramiko========================= python ssh模块: import paramiko def ssh(host,cmd): #host = ‘192.168.0.213‘ user = ‘root‘ s = paramiko.SSHClient() s.load_system_host_keys() s.set_missing_host_key_policy(paramiko.AutoAddPolicy()) privatekeyfile = os.path.expanduser(‘~/.ssh/id_rsa‘) mykey = paramiko.RSAKey.from_private_key_file(privatekeyfile) # mykey=paramiko.DSSKey.from_private_key_file(privatekeyfile,password=‘061128‘) s.connect(host,22,user,pkey=mykey,timeout=5) #cmd=raw_input(‘cwd:‘) #cmd="ip a | grep inet | grep 192.168 | grep brd | awk -F/22 ‘{print $1}‘|awk ‘{print $2}‘" stdin,stdout,stderr = s.exec_command(cmd) cmd_result = stdout.read(),stderr.read() for line in cmd_result: return line.strip("\n") s.close() print ssh("192.168.0.2",‘ls /root‘) ==========multiprocessing============= import multiprocessing def bingfa(picmip): Srealmount=set(ssh(picmip,"mount|awk ‘$1~/192.168.0.7/{print $1}‘").rstrip().split("\n")) #print Srealmount shortlist=list(Slocalmountls - Srealmount) for sl in shortlist: print "mount-error-"+sl + time.ctime() f=open(‘/share/yunwei/shell/mountip.txt‘) pool=multiprocessing.Pool(processes=4) for ips in f: pool.apply_async(bingfa,(ips,)) pool.close() pool.join() f.close() ========MySQLdb=============== python mysql模块: import MySQLdb def pyfmysql(*args): conn=MySQLdb.connect(host=‘10.0.0.24‘,user=‘root‘,passwd=‘xxxxx‘,db=‘mon‘,port=3306) cur=conn.cursor() conn.select_db(‘monitor‘) cur.execute("""insert into T_SYS_LOG (CONTENT,HOST_IP,MONITOR_TYPE,MONITOR_LEVEL,SMS_FLAG,GROUP_ID) values(%s,%s,%r,%r,%r,%r)""",args) #sqlcmd=‘insert into T_SYS_LOG(CONTENT, HOST_IP, MONITOR_TYPE, MONITOR_LEVEL, SMS_FLAG,GROUP_ID) values(%s,%s,%s,%d,%d,%d)‘ sqlresult = cur.fetchall() print sqlresult conn.commit() cur.close() conn.close() pyfmysql(‘test‘,‘127.0.0.1‘,1,2,0,6) ==========json============= import json newd={‘four‘: ‘192.168.0.10‘, ‘second‘: ‘192.168.0.5‘, ‘third‘: ‘192.168.0.7‘, ‘first‘: ‘192.168.0.2‘} ojson=json.dumps(newd) file=open(‘/tmp/jsonfile‘,‘w‘) file.write(ojson) f= open(r‘/tmp/jsonfile‘) jsonobj = json.load(f) oldd=eval(str(jsonobj)) f.close =========shutil================== import shutil shutil.copy("1","2") shutil.rmtree("42") =========cStringIO=============== import cStringIO 输入: s=cStringIO.StringIO() s.write("you are a girl") 输出: print s.getvalue() 或者 s.seek(0) print s.read() =============time================= import time passt = datetime.datetime.now() - datetime.timedelta(minutes=10) curtime2 = passt.strftime(‘%Y%m%d%H‘) ==============urllib================= import urllib >>> ourl=urllib.urlopen(‘http://www.baidu.com‘) >>> print ourl.info() >>> for line in ourl: print line, >>> google.close() import urllib print urllib.urlopen(‘http://www.google.com‘).read() ============urllib2================ #!/bin/env python import urllib2 # set up authentication info authinfo = urllib2.HTTPBasicAuthHandler() authinfo.add_password(realm=‘PDQ Application‘, uri=‘http://10.0.0.1:8091/index.html‘, user=‘admin‘, passwd=‘admin‘) #proxy_support = urllib2.ProxyHandler({"http" : "http://ahad-haam:3128"}) # build a new opener that adds authentication and caching FTP handlers opener = urllib2.build_opener(authinfo,urllib2.CacheFTPHandler) # install it urllib2.install_opener(opener) f = urllib2.urlopen(‘http://10.0.0.1:8091/index.html#sec=servers‘) text=f.read() print text
