----后端配置（客户端和服务端时间必须准确）----<br>

一、服务端（Centos7）<br>

1.配置步骤<br> yum install -y golang<br>

sudo yum install mariadb-servergo

sudo systemctl start mariadb<br> sudo systemctl enable mariadb

sudo systemctl status mariadb

mysql_secure_installation //初始化mariadb paswd:123456<br> sudo systemctl stop firewalld.service<br> setenforce 0<br>

2.导入数据库表(pingmesh.sql)

3.编译（pingmesh-s-v1.1-GetResult.go/pingmesh-s-v1.1-GetHostIp.go）<br> go build pingmesh-s-v1.1-GetResult.go<br> go build pingmesh-s-v1.1-GetHostIp.go<br>

4.运行<br> nohup ./pingmesh-s-v1.1-GetResult > output.log 2>&1 &<br> nohup ./pingmesh-s-v1.1-GetHostIp > output.log 2>&1 &<br>

二、客户端<br>

1.基础安装<br> yum install epel-release -y<br> yum install fping -y<br>

2.编译后端（pingmesh-c-v1.1.go）<br> go build pingmesh-c-v1.1.go<br>

3.运行<br> nohup ./pingmesh-c-v1.1 > output.log 2>&1 &<br>

----前端配置----<br>

修改参数pingmesh.py<br> conn = pymysql.connect(<br> host='172.19.129.11',<br> user='root',<br> password='123456',<br> db='ping',<br> charset='utf8'<br> )<br> 部分<br>

1.运行项目<br> python pingmesh.py<br> 后台运行：nohup python pingmesh.py > pingmeshpy.log 2>&1 &

2.结果显示<br> 访问http://127.0.0.1:9000<br>

3.报错

ImportError: No module named flask yum install python-pip -y<br> pip install flask

ImportError: No module named pymysql<br> pip install pymysql
