使用python監控mysql的主從複製的方法

利用python來檢查MySQL的主從複製，

有一個注意點是，cur.execute("show slave status;") 不能用cur.execute("show slave status\G;")

result = cur.fetchall()

返回的是個二元數組

result[0] 返回時整個show slave status 狀態資訊。

result[0][n] 返回具體的某一項。

python代碼如下：

#!/usr/bin/env python

#-*- coding: utf-8 -*-

import MySQLdb, socket, paramiko,sys, os,datetime

def final_check_mysql ():

status = True

try:

conn=MySQLdb.connect(host='192.168.3.10',user='root',passwd='Xp29at5F37',db='test')

cur=conn.cursor()

cur.execute("show slave status;")

result = cur.fetchall()

io_thread= result[0][10]

sql_thread= result[0][11]

print io_thread,sql_thread

cur.close()

conn.close()

except Exception,e:

print Exception,":",e

status = True

try:

if io_thread == "Yes" and sql_thread == "Yes":

print 'MySQL master/slave replication status is successfully'

else:

print 'MySQL Master/Slave replication fail,Please check it'

status = False

except Exception,e:

print Exception,":",e

#return status

go=final_check_mysql()
