使用 Docker 部署 ServerStatus 服务器监控系统

一、ServerStatus 介绍

GitHub：https://github.com/cppla/ServerStatus

ServerStatus 是一个酷炫高逼格的云探针、云监控、服务器云监控、多服务器探针~。

特性

• 使用 Rust 完全重写 Server、Client，单个执行文件部署
• 支持上下线和简单自定义规则告警 (Telegram、 Wechat、 Email、 Webhook)
• 支持 http 协议上报，可以方便部署到各免费容器服务和配合 cf 等优化上报链路
• 支持 vnstat 统计月流量，重启不丢流量数据
• 支持 Railway 快速部署
• 支持 Systemd 开机自启

二、检查宿主机系统版本

cat /etc/os-release

三、检查本地 Docker 环境

检查 Docker 服务状态

// 1) 低版本 Docker 安装
yum install docker -y

----
// < '推荐' >
// 2) 高版本 Docker 安装
curl -fsSL https://get.docker.com/ | sh

----
// 关闭防火墙
systemctl disable --now firewalld
setenforce 0

// 启用 Docker
systemctl enable --now docker

检查 Docker 配置信息

docker info

开启 IPv4 forwarding

echo "net.ipv4.ip_forward=1" >>  /etc/sysctl.conf
systemctl restart network
sysctl net.ipv4.ip_forward

四、安装 Docker-compose

下载 Docker-compose 二进制包

curl -L https://github.com/docker/compose/releases/download/v2.2.2/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose

给文件增加执行权限

chmod +x /usr/local/bin/docker-compose

检查 Docker-compose 版本

docker-compose -v

五、下载 ServerStatus 镜像

docker pull stilleshan/serverstatus

六、使用 Docker-cli 部署

mkdir /docker/ServerStatus/server -p && cd /docker/ServerStatus/server

( 省略 )
docker run -d --name=serverstatus --restart=always \
  -p 8888:80 \
  -p 35601:35601 \
  -v /docker/ServerStatus/server/config.json:/ServerStatus/server/config.json \
  stilleshan/serverstatus

七、下载 ServerStatus 安装文件

创建数据目录

mkdir /docker/ServerStatus/server -p && cd /docker/ServerStatus/server

下载安装文件

yum install git -y

git clone https://github.com/stilleshan/ServerStatus.git

[root@localhost ServerStatus]# ls
config.json  docker-compose.yml  Dockerfile  README.md  screenshot.jpg  status.sh  web

查看 Docker-compose.yaml 文件

[root@localhost ServerStatus]# vim docker-compose.yml
version: "3"
services:
  serverstatus:
    image: stilleshan/serverstatus
    container_name: serverstatus
    ports:
      - 8888:80
      - 35601:35601
    volumes:
      # - ./web:/usr/share/nginx/html
      - ./config.json:/ServerStatus/server/config.json
    environment:
      TZ: Asia/Shanghai
    restart: always

创建 ServerStatus 容器

docker-compose up -d

查看 ServerStatus 容器状态

docker ps

八、访问 ServerStatus 服务端

九、客户端安装

修改 status-client.py

在客户端运行 status-client.py 脚本

[root@node01 ~] python status-client.py &
[1] 105194

服务端配置

修改 config.json 文件，必须配置项为 username/password/host

[root@server ServerStatus] vim config.json 
{"servers":
 [
  {
   "username": "admin",					# 客户端账号
   "password": "admin",					# 客户端密码
   "name": "腾讯云-上海",
   "type": "KVM",
   "host": "192.168.80.18",			# 填写客户端 IP 地址
   "location": "CN",
   "disabled": false
  },
  {
   "username": "2",
   "password": "xxx",
   "name": "阿里云-香港",
   "type": "KVM",
   "host": "None",
   "location": "HK",
   "disabled": false
  },
  {
   "username": "3",
   "password": "xxxx",
   "name": "谷歌云-日本",
   "type": "KVM",
   "host": "None",
   "location": "JP",
   "disabled": false
  }
 ]
}
