数据库连接

　　

脚本中使用mysql连接

定义一个装饰器

import pymysql
def ana_r(func):
    def conn(*args,**kwargs):
        conn = pymysql.connect(host='172.16.17.10', user='admin_sa', password='pwd4sa#2017', database='analytics',port=3841, charset='utf8')
        db = conn.cursor()
        result = func(db,*args,**kwargs)

        conn.close()
        return result
    return conn


然后引入

from mysql_conn import ana_r
@ana_r
def test(db):
    sql='select * from analytics.apm_jvm_mem ORDER by datetime limit 100'
    row=db.execute(sql)
    print(row)
test()

django中使用

import pymysql
def jvm_monitor(request):
    conn = pymysql.connect(host='172.16.17.10', user='sunkedong', password='123456', database='analytics',
                           port=3841, charset='utf8')
    db = conn.cursor()
    sql = 'select * from analytics.apm_jvm_mem ORDER by datetime limit 100'
    row = db.execute(sql)
    return render(request,'jvm_monitor.html',locals())
