##先使用MySQLdb的接口关联数据库。

[root@cml python]# cat check_Mysql_custom.py#!/usr/local/bin/python'''author = chenmingle''''''Description:get mysql status'''import osimport systry:    import MySQLdb as mysqlexcept Exception, e:    print e    print "pip install MySQL-python"    sys.exit(1)con = mysql.connect(host='localhost',user='root',passwd='passwd',)def processlist():cur = con.cursor()sql1 = 'show processlist'a = str(cur.execute(sql1))print adef slave_status():        cur = con.cursor()        sql2 = cur.execute('show status like "%Slave_running%";')        status2 = str(cur.fetchall())        check2 = status2.split("'")[3]        if check2 == 'ON':                print 0        else:                print 1def show_status(type):cur = con.cursor()b = cur.execute('show status like "%s";' %(type))for i in cur.fetchall():cat = str(i)check = str(cat.split("'")[3])print checkdef main(type):   if type == 'processlist':processlist()   elif type == 'slave_status':slave_status()   else:show_status(type)if __name__ == '__main__':    try:        type = sys.argv[1]    except Exception, e:        print "Usage: python %s type" % sys.argv[0]        sys.exit(1)    main(type)

假如执行测试时报以下错误:

[root@cml python]# python check_Mysql_custom.py slave_status

Traceback (most recent call last):

  File "test.py", line 14, in <module>

    con = mysql.connect(user='zabbix',passwd='',port=3306)

  File "/usr/local/lib/python2.7/site-packages/MySQLdb/__init__.py", line 81, in Connect

    return Connection(*args, **kwargs)

  File "/usr/local/lib/python2.7/site-packages/MySQLdb/connections.py", line 193, in __init__

    super(Connection, self).__init__(*args, **kwargs2)

_mysql_exceptions.OperationalError: (2002, "Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)")

[root@cml python]# mkdir /var/lib/mysql[root@cml python]# ln -s /tmp/mysql.sock /var/lib/mysql/mysql.sock

##测试一下脚本:

[root@cml python]# python check_Mysql_custom.py processlist3[root@cml python]# python check_Mysql_custom.py Connections55876

##测试显示所有在mysql中show status的都可以输出信息出来:

##写一个模板配置文件(自定义key值):

[root@cml zabbix_agentd.d]# cat Mysql_Custom.confUserParameter=mysql.Custom[*],/usr/local/bin/python /home/python/check_Mysql_custom.py $1

##在zabbix web界面上加入模板:

##增加一个Appaliactions:

##加入item值:
