今天感觉网络有点波动，于是又想搭一个Smokeping。记得它有Docker版本的，可以一把梭，无需头疼各种依赖和报错。很简单，只需8步。 icon_wink.png

  • 2022-10-15 更新了修改resolve.conf的正确方式

1. 安装 Docker Engine

Debian

设置 Docker 软件源

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg

# Add the repository to Apt sources:
echo \
  "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/debian \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

安装 Docker Engine 组件

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

运行演示程序看是否安装成功

sudo docker run hello-world

CentOS

删除旧组件

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

安装 yum-utils ，设置 Docker 软件源。

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

安装 Docker Engine 组件

sudo yum install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

开启 Docker 服务

sudo systemctl start docker

运行演示程序，看安装是否成功

sudo docker run hello-world

Docker Engine 在其他操作系统，其他安装方式参考官网。

2 安装 Docker-compose

Ubuntu 和 Debian

sudo apt-get update
sudo apt-get install docker-compose-plugin

CentOS

sudo yum update
sudo yum install docker-compose-plugin
$ docker compose version
Docker Compose version v2.21.0

2. 获取镜像，修改镜像，创建docker-compose配置文件

创建目录/usr/local/smokeping来存放本项目相关文件。

mkdir /usr/local/smokeping
cd /usr/local/smokeping
nano docker-compose.yml

输入以下内容，完成后按Ctrl+X，再按Y，回车。

version: "2.1"
services:
  smokeping:
    image: ghcr.io/linuxserver/smokeping
    container_name: smokeping
    hostname: GZ_Telecom
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Shanghai
    volumes:
      - ./config:/config
      - ./data:/data
    ports:
      - 50000:80
    restart: unless-stopped
    network: bridge

位于大陆的服务器需要修改镜像中的resolve.conf文件。所有操作均在/usr/local/smokeping/目录，步骤：

  1. 创建自定义resolve.conf
    touch resolve.conf && echo "nameserver 223.5.5.5" > resolve.conf

  2. 创建一个Dockerfile文件用于拉取并修改镜像，
    Dockerfile内容如下：

    FROM linuxserver/smokeping:latest
COPY ./resolve.conf /etc/resolve.conf

  3. docker-compose.yml文件改为以下内容

    version: "2.1"
services:
  smokeping:
 build: ./
 container_name: smokeping
 hostname: GZ_Telecom
 environment:
   - PUID=1000
   - PGID=1000
   - TZ=Asia/Shanghai
 volumes:
   - ./config:/config
   - ./data:/data
 ports:
   - 50000:80
 restart: unless-stopped
  • 配置文件存放目录为/usr/local/smokeping/config。
  • 数据文件存放地址为/usr/local/smokeping/data。
  • 外部访问端口为50000，因为我这台机器有多个服务，80端口留给Nginx。这里先设为50000，再去Nginx里面反代。

3. 试运行

运行docker compose up。境内服务器应该很慢，多试几次。
没问题就按Ctrl C退出运行。

4. 添加要监测的目标

编辑/usr/local/smokeping/config/Targets文件，按照格式输入要检测的目标。

*** Targets ***

probe = FPing

menu = Top
title = Network Latency Grapher
remark = Welcome to the SmokePing website of WORKS Company. \
         Here you will learn all about the latency of our network.

+ US
menu = 美国
title = 在美国的服务器

++ RFCHost
menu = RFCHost(GIA) - LA
title = RFCHost(GIA), 洛杉矶
host = 103.1.1.1

++ GGC
menu = GGC(GIA) - LA
title = GGC(GIA), Los Angels
host = 103.1.1.1

++ 这里填标识符，可以用大小写英文字母、数字、下划线和减号，用正则表达式就是/[-_0-9a-zA-Z]+/
menu = 菜单显示的内容
title = 页面顶部显示的内容
host = 要ping的目标，域名和IP都行

+ EU
menu = 欧洲
title = 在欧洲的服务器

++ Online
menu = Online - NL
title = 就是Online.net的服务器
host = 51.1.1.1

+ eu-ipv6
probe = FPing6

menu = EU IPv6
title = 欧洲的IPv6服务器

++ Online
menu = Online - NL
title = 就是Online.net的服务器
host = 2001:abcd::1

5. 国内服务器需要做的改动

编辑/usr/local/smokeping/config/Probe文件，将以下DNS里面的lookup改为国内网络能够连接的网址，比如百度。

+ DNS
binary = /usr/bin/dig
lookup = baidu.com
pings = 5
step = 300

6. 启动容器

回到/usr/local/smokeping/目录，以后台方式启动容器docker-compose up -d

7. 等待10分钟，进入http://服务器IP:50000查看结果。

不等可以直接打开，只是没有数据而已。

8. 开启反代

server_name，certificate请根据自己实际情况修改。

server{
    server_name ping.fly2x.cn;
    listen 80;
    return 301 https://$host$request_uri;
}

server{
    server_name ping.fly2x.cn;
    listen 443 ssl http2;
    access_log /home/wwwlogs/ping.log combined;
    ssl_certificate /etc/ssl/fly2x.cer;
    ssl_certificate_key /etc/ssl/fly2x.key;
    keepalive_timeout   70;
    ssl_session_timeout 24h;
    ssl_buffer_size 4k;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
    ssl_prefer_server_ciphers on;
    ssl_dhparam ssl/dhparam.pem;
    ssl_ciphers "ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4:!DH:!DHE";
    ssl_session_cache builtin:1000 shared:SSL:10m;
    ssl_stapling on;
    ssl_stapling_verify on;
    ssl_trusted_certificate /etc/ssl/fly2x.cer;

    location / {
        proxy_pass  http://127.0.0.1:50000;
        proxy_set_header   Host  $host;
        proxy_redirect     off;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;
    }
}

9. 常用操作

1. Docker命令

  • 进入Docker镜像内部
    docker exec -it smokeping /bin/bash
  • 重启镜像
    docker-compose restart
  • 查看日志输出
    docker logs smokeping

2. 自定义检测频率

编辑/usr/local/smokeping/config/Database。
step：多少秒时间ping一轮
pings： 每个节点ping多少下

*** Database ***
step     = 180
pings    = 20

3. 修改主节点名称

就是图里红框的名称
hostname-problem.png
编辑/usr/local/smokeping/config/General，添加一个display_name

*** General ***

owner    = 王小明
contact  = [email protected]
mailhost = mail.fly2x.cn
# NOTE: do not put the Image Cache below cgi-bin
# since all files under cgi-bin will be executed ... this is not
# good for images.
cgiurl   = http://localhost/smokeping.cgi
# specify this to get syslog logging
syslogfacility = local0
# each probe is now run in its own process
# disable this to revert to the old behaviour
# concurrentprobes = no

display_name = 广州腾讯云
@include /config/pathnames

10. 遇到的问题

  1. xxx.rrd file not exist
    国内服务器需要进入镜像内部，命令见步骤九，修改/etc/resolve.conf，添加一个国内可用的DNS。

    nameserver 223.5.5.5

    虽然Docker强烈建议大家不要修改镜像里面的文件，而是在docker-compose.yml文件通过定义volumn来修改，但是我试过没用啊，先这么用着吧。等我以后学会了再说。
    好了，我学会了。见步骤二。

11. 启用IPv6

来源
编辑 /etc/docker/daemon.json ，加上以下内容。

{
  "ipv6": true,
  "fixed-cidr-v6": "fd00::/80",
  "experimental": true,
  "ip6tables": true
}

重启docker enginesudo systemctl restart docker.

docker-compose.yaml增加一行network_mode: bridge

version: "2.1"
services:
  smokeping:
    build: ./
    container_name: smokeping
    hostname: GZ_CT
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Asia/Shanghai
    volumes:
      - ./config:/config
      - ./data:/data
      - ./resolve.conf:/etc/resolve.conf
    ports:
      - 50000:80
    restart: unless-stopped
    network_mode: bridge
