如何用python编写的简单的mysql巡检脚本，相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。 准备工作： 1 安装python 3.5，本次使用源码安装。 2 安装psutil模块，使用python3.5自带的easy_install包直接运行 cd /opt/python3/bin ./easy_install-3.5 psuitl安装 3 安装mysql_connector模块，同样使用easy_install安装 easy_install-3.5 mysql-connector==2.1.4 准备工作完成后便可运行如下脚本： [mysql@jing1 scripts]$ more healthcheck.py #!/usr/bin/env python3 # -*- coding: gbk -*- import psutil import mysql.connector import argparse import json import datetime def get_cpu_info(verbose): cpu_info={} if verbose >0: print("[cpu] start collect cpu info ...")
