linux下用python写的一个syslog服务进程脚本

江南才子

　　最近在折腾rsyslog+loganalyzer+mysql，搭建OK，无奈rsyslogd识别华为交换机输出日志的格式有点偏差，只能自己在rsyslog服务器上重新写一个进程，用来接收华为交换机的info-center，并写入数据库里，代码如下（基本没做错误检测机制）

#!/usr/bin/python
import MySQLdb,time,datetime
from socket import *
host = '172.16.0.45'
port = 514
addr = (host,port)
s = socket(AF_INET,SOCK_DGRAM)
s.bind(addr)
db = MySQLdb.connect('172.16.0.45','rsyslog','p@ssw0rd','Syslog')
cursor = db.cursor()
cursor.execute('select version()')
data = cursor.fetchone()
print 'data ver is ', data
Mothlist = {'Jan':1,'Feb':2,'Mar':3,'Apr':4,'May':5,'Jun':6,'Jul':7,'Aug':8,'Sep':9,'Oct':10,'Nov':11,'Dec':12}
while 1:
    client_data,client_addr = s.recvfrom(8092)
    print 'got connection from ',client_addr
    if '172.16.201.' not in str(client_addr):
      print 'can not connect from except 172.16.201.0/24',str(client_addr)
      continue
    #file = open('log.txt','a')
    #file.write(client_data + '\n')
    #file.close()

datalist = client_data.split(' ')
    print 'datalist = ',datalist
    Moth = datalist[0][-3:]
    Year = datalist[2]
    Day = datalist[1]
    SWtime = datalist[3].split('+')[0]

templist = datalist[5].split('/')
    print 'templist = ',templist
    Facility = templist[0]
    Priority = templist[1]
    ReportTime =  Year +  '-' + str(Mothlist[Moth]) + '-' + Day +' '+ SWtime
    RecvTime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime())
    FromHost = datalist[4]
    client_ip = client_addr[0]
    SysLogTag = templist[2]
    Message = ''
    #print datalist
    for m in range(0,len(datalist)):

print 'm is ',m

try:Message = Message + datalist[5+m]
        except:pass

print 'msg is', Message

sql = "INSERT INTO SystemEvents(Priority,ReceivedAt,DeviceReportedTime, FromHost, FromIP,SysLogTag, Message) VALUES ('%s', '%s', '%s','%s','%s','%s','%s')" %(Priority,RecvTime,ReportTime,FromHost,client_ip,SysLogTag,Message)

sql = """INSERT INTO SystemEvents(ReceivedAt,DeviceReportedTime, FromHost, FromIP, Message) VALUES ('2015-08-08 8:8:8', '2018-9-9 9:9:9', 'host test', '2.2.2.2', 'messssss')"""

#print 'sql is :',sql

cursor.execute(sql)
    db.commit()
    #print '*'*20

db.close()
最后，用后台免登陆执行

nohup sw_logserver.py &
