检查mysql主从重要表数据一致性

mysql数据库主从做起来不难,但是主从数据的一致性很重要,本脚本用于粗略检查mysql数据库主从重要表的数据一致性,主要是在主从正常的情况下,连接数据库统计表的条数是否一致,脚本分为两部分,一个是py脚本,一个是ini配置文件,py脚本源码如下:

#!/usr/bin/env python
#This script is used check mysql replcation some table
# -*- coding: utf-8 -*-
import sys,time,MySQLdb,threading
import ConfigParser
class Check:
    def __init__(self):
        self.w =[]
        self.table = table
    def conf(self):
        fp = ConfigParser.ConfigParser()
        fp.readfp(open('config.ini'))
        iplist = fp.get("global", "iplist")
        return iplist
             
    def wd(self,table):
        iplist = self.conf()
        hostlist = []
        self.w = []
        threads = []
        for i in iplist.split(";"):
            hostlist.append(i.split(","))
        for i in range(len(hostlist)):
            host = hostlist[i][0]
            hostname = hostlist[i][1]
            t = threading.Thread(target=self.mysql_check,args=(host,hostname,i))
            threads.append(t)
            t.start()
            time.sleep(0.05)
        for i in range(len(hostlist)):
            threads[i].join()
        self.w.sort()
        for r in range(len(self.w)):
            print self.w[r]
             
    def mysql_check(self,host,hostname,i):
        try:
            conn = MySQLdb.connect(host = host,user = 'user',passwd = 'passwd',connect_timeout=5)
            cursor = conn.cursor() 
            sql = "SELECT COUNT(*) FROM %s" % self.table
            cursor.execute(sql)
            alldata = cursor.fetchall()
            count = alldata[0][0]
            value = hostname + "\t" + str(count)
            self.w.append(value)
        except:
            print "Can not Connect to " + host + " mysql server"
            return 0
             
if __name__ == "__main__": 
    table_list = ['aa.aa','bb.bb','cc.cc']
    for i in range(len(table_list)):
        table = table_list[i]
        print "Table Count:  " + table
        print
        boss = Check()
        boss.wd(table)
        print

config.ini 文件格式如下

[global]
iplist = 192.168.50.1,vvv(主);192.168.50.2,vvv(从);192.168.50.3,ttt(主);192.168.50.4,ttt(从)
