##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)

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

[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:
