Ubuntu 22.04 通过 Docker 启动 Graylog

安装 Docker 和 Docker-Compose

这里以 Ubuntu 22.04 举例，如果你和我的系统一样，那么可以照抄下面这个命令来快速安装 docker。如果不是，你也可以 点击这里 来跳转到 Docker 官网来实现安装。

#!/bin/bash
apt-get update
apt-get -y install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | apt-key add -
echo | add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
apt-get update
apt-get -y install docker-ce docker-ce-cli containerd.io

接下来需要安装 Docker-Compose

apt update
apt install docker-compose

将一些配置文件和数据文件映射到本地

mkdir -p /home/graylog/mongo_data && chmod -R +777 /home/graylog/mongo_data
mkdir -p /home/graylog/es_data && chmod -R +777 /home/graylog/es_data
mkdir -p /home/graylog/graylog_data && chmod -R +777 /home/graylog/graylog_data
mkdir -p /home/graylog/graylog_data/config
cd /home/graylog/graylog_data/config 
wget https://raw.githubusercontent.com/Graylog2/graylog-docker/4.2/config/graylog.conf
wget https://raw.githubusercontent.com/Graylog2/graylog-docker/4.2/config/log4j2.xml
chown -R 1100:1100 /home/graylog/graylog_data
cd /home/graylog

如果上面的文件下载（wget命令）不了，那么可以先通过别的手段下载下来，然后上传到服务器对应的位置即可。

修改 Graylog 配置文件

接下来执行 vim graylog.conf，内容改成下面这个

root_timezone = PRC
allow_highlighting = true

Graylog 密码生成

在 linux 系统下执行下面这个命令来生成 SHA-256 的密码

echo -n "my_password" | sha256sum

windows powershell 可以执行这个

echo -n my_password | certutil -hashfile - SHA256

Docker Compose

修改下面配置中的 GRAYLOG_PASSWORD_SECRET 和 GRAYLOG_ROOT_PASSWORD_SHA2。

version: '3'

  # MongoDB: https://hub.docker.com/_/mongo/
  mongodb:
    image: mongo:4.2

    environment:

      - GRAYLOG_PASSWORD_SECRET=somepasswordpepper
      # 这里的 SHA-2 对应的密码原文为：admin，你需要修改它，命令就是上面的 SHA 密码生成部分
      - GRAYLOG_ROOT_PASSWORD_SHA2=8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918

    links:
        - mongodb:mongo
        - elasticsearch
    restart: always
    depends_on:
      - mongodb
      - elasticsearch
    ports:
      # Graylog web interface and REST API
      - 9000:9000
      # Syslog TCP
      - 1514:1514
      # Syslog UDP
      - 1514:1514/udp
      # GELF TCP
      - 12201:12201
      # GELF UDP
      - 12201:12201/udp

执行下面这个命令就可以启动了，-d 代表后台启动，如果你想要在台前看一下启动的过程，那么你可以去掉这个参数。

docker-compose up -d

异常情况：

ubuntu 22.04 在执行 docker-compose up 的时候，可能会抛出如下错误，主要的原因是：
docker.errors.DockerException: Error while fetching server API version: HTTPConnection.request() got an unexpected keyword argument 'chunked'

完整报错如下：

During handling of the above exception, another exception occurred:

    raise DockerException(
docker.errors.DockerException: Error while fetching server API version: HTTPConnection.request() got an unexpected keyword argument 'chunked'

这个错误是 python 的 request 包的版本不正确导致的，你可以执行下面这个命令来查看你本地的 request 包的版本

pip list |grep request
> requests 2.31.0

接下来只要安装一个合适的版本即可：

pip install requests==2.28.0
