nginx syslog 配置

以下是一个简单的实践,主要是打算测试nginx 与graylog 的集成,为了简单都是使用容器运行的,同时也测试了
nginx 对于配置多个access_log 的处理

环境准备

  • docker-compose 文件
 
version: "3"
services: 
  log:
    image: openresty/openresty:alpine
    ports: 
    - "8080:8080"
    volumes: 
    - "./nginx.conf:/usr/local/openresty/nginx/conf/nginx.conf"
    - "./log1:/opt/log1"
    - "./log2:/opt/log2"
  syslog:
    image: balabit/syslog-ng
    ports: 
    - "514:514/udp"
    - "601:601"
    - "6514:6514"
  • nginx 配置

    使用openresty

worker_processes 1;
user root;  
events {
    worker_connections 1024;
}
http {
    include mime.types;
    default_type application/octet-stream;
    sendfile on;
    lua_code_cache off;
    lua_need_request_body on;
    gzip on;
    resolver 127.0.0.11 ipv6=off;          
    real_ip_header X-Forwarded-For;
    real_ip_recursive on;
    gzip_min_length 2k;
    gzip_buffers 4 16k;
    log_format compression '$remote_addr - $remote_user [$time_local] '
                       '"$request" $status $bytes_sent '
                       '"$http_referer" "$http_user_agent" "$gzip_ratio"';
    gzip_comp_level 4;
    gzip_types text/plain text/css image/png application/javascript image/jpeg image/gif;
    server {
        listen 8080;
        server_name _;
        charset utf-8;
        #  此处配置多个,主要目的是方便 nginx 端的查看以及日志server 信息的查看 
        access_log /opt/log1/nginx-access.log compression buffer=32k;
        access_log /opt/log2/nginx-access.log compression buffer=32k;
        access_log syslog:server=syslog,facility=local7,tag=nginx,severity=info,nohostname compression;
        default_type text/html;
        location / {
           default_type text/plain;
           index index.html index.htm;
        }
        location = /favicon.ico {
            root /opt/app/static;
        }
        location = /empty {
            empty_gif;
        }
        error_page 500 502 503 504 /50x.html;
        location = /50x.html {
            root html;
        }
    }

启动&&测试

  • 启动
docker-compose up -d
  • 效果
    本地文件

nginx syslog 配置_编程

 


syslog:
syslog 的日志需要进入容器查看,可以使用如下命令

 
tail -f /var/log/messages
  • 增强
    如果启用了graylog 的syslog udp input,我们就可以通过graylog 处理log 了,参考效果

说明

实际实践中为了方便我们可以同时添加本地的log 以及基于graylog 的log 处理,同时基于graylog 强大的分析,以及数据处理能力,可以做好多数据上的分析
