Graylog2实现Docker容器日志收集

Posted 2021-01-12

Graylog2 是一个开源的日志存储系统,是由java语言编写的server,能够接收TCP,UDP,AMQP的协议发送的日志信息,并且基于mongodb数据库服务器快速存储,能够通过一个基于ruby编写的web管理界面,让轻松管理你的日志。

1、组件准备	名称	组件名称	备注
1	mongodb
2	elasticsearch
3	graylog2

2.安装
使用Docker-compose部署
docker-compose安装,参考:http://hujianxiong.com/linuxan-zhuang-docker-compose/

docker-compose文件:

version: ‘2‘
services:
mongo:
image: "mongo:3"
restart: always
volumes:

• /workspace/data/graylog/data/mongo:/data/db
  elasticsearch:
  image: "elasticsearch:2"
  command: "elasticsearch -Des.cluster.name=‘graylog‘"
  volumes:
  • /workspace/data/graylog/data/elasticsearch:/usr/share/elasticsearch/data
    restart: always
    graylog:
    image: graylog2/server
    volumes:
• /workspace/data/graylog/data/journal:/usr/share/graylog/data/journal
• /workspace/data/graylog/config:/usr/share/graylog/data/config
  environment:
  GRAYLOG_PASSWORD_SECRET: somepasswordpepper
  GRAYLOG_ROOT_PASSWORD_SHA2: 8c6976e5b5410415bde908bd4dee15dfb167a9c873fc4bb8a81f6f2ab448a918
  #GRAYLOG_WEB_ENDPOINT_URI: http://0.0.0.0:9000/api/
  GRAYLOG_REST_TRANSPORT_URI: http://10.250.160.33:12900
  depends_on:
  • mongo
  • elasticsearch
    links:
  • mongo:mongo
  • elasticsearch:elasticsearch
    ports:
  • "9000:9000"
  • "12900:12900"
  • "12201/udp:12201/udp"
  • "1514/udp:1514/udp"
    restart: always
    3.下载配置文件
    [[email protected] ~]# mkdir -p /workspace/data/graylog/config
    [[email protected] ~]# cd /workspace/data/graylog/config
    [[email protected] config]# wget https://raw.githubusercontent.com/Graylog2/graylog2-images/2.1/docker/config/graylog.conf
    [[email protected] config]# wget https://raw.githubusercontent.com/Graylog2/graylog2-images/2.1/docker/config/log4j2.xml
    4.部署
    [[email protected] ~]# docker-compose up -d
    5.Graylog配置接收日志
    登录 http://10.250.160.32:9000 admin/admin
    配置system==>input==>select input ===>GELF UDP

6.修改Docker daemon启动参数
–log-driver=gelf
–log-opt gelf-address=udp://10.250.160.32:12201
–log-opt gelf-compression-type=gzip
–log-opt gelf-compression-level=1
–log-opt tag=”test01_env”

7.重启daemon
[[email protected] ~]# systemctl daemon-reload
[[email protected] ~]# systemctl restart docker
启动容器后在Graylog管理界面就可以看到接收的日志了
