[玩转nginx] tengine加入nginx-module

开启nginx-module-vts功能

默认的tengie不包括nginx-module-vts功能,需要我们自己自定义加入此模块即可，目前我们使用tengine都是基于docker容器，于是笔者自己根据Dockerfile构建了自定义的镜像，Dockerfile见附文

学习nginx-module-vts可参考 vts Github

基于docker启动tengine并开启vts功能

• 配置docker-compose

tengine:
    container_name: tengine
    image: docker.today36524.com.cn:5000/basic/tengine:2.0.4
    restart: on-failure:3
    environment:
      - LANG=zh_CN.UTF-8
      - TZ=CST-8
    volumes:
      - /data/config/nginx/conf.d/:/etc/nginx/conf.d/
      - /home/today/tscompose/config/nginx.conf:/etc/nginx/nginx.conf
      - /data/config/nginx/cert/:/etc/nginx/cert/
      - /data/logs/nginx:/var/log/nginx
    ports:
      - "80:80"
      - "443:443"

• 配置tengine主配置文件 容器内路径 /etc/nginx/nginx.conf

user  nginx;
worker_processes  8;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;

worker_rlimit_nofile 65535;

events {
    worker_connections  10240;
}

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;
    # 开启 vts 监控功能
    vhost_traffic_status_zone;

    log_format  main  '$remote_addr||$time_local||"$request"||'
                      '$status||$body_bytes_sent||"$http_referer"'
                      '||$http_x_forwarded_for||'
                      '||$upstream_status||$upstream_addr||$request_time||$upstream_respo


    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  120;

    gzip on;
    gzip_buffers 16 8k;
    gzip_comp_level 5;
    gzip_disable "MSIE [4-6]\."
    gzip_min_length 1000;
    gzip_http_version 1.1;
    gzip_proxied any;
    gzip_types text/plain text/css application/xml application/javascript application/jso
    gzip_vary on;

    include /etc/nginx/conf.d/*.conf;
}

只需要在主配置文件中http模块下加入一行配置即可

 vhost_traffic_status_zone;

• 在自定义的配置文件中开启监控功能

upstream maple {
    server 192.168.10.8:9101;
    server 192.168.10.8:9102;
    # health check
    check interval=3000 rise=2 fall=3 timeout=1000 type=http;
    check_http_send "HEAD /health/check  HTTP/1.0\r\n\r\n";
    check_http_expect_alive http_2xx http_3xx;
}

server {
    listen 80;
    server_name localhost;

    access_log  /var/log/nginx/gateway.log;
    error_log /var/log/nginx/gateway-error.log;

    keepalive_timeout 300;
    send_timeout 300;
    proxy_read_timeout 300;

    location / {
        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

        proxy_pass http://maple;
    }

    location /ngx_status {
        stub_status on;
        # vts功能
        vhost_traffic_status_display;
        vhost_traffic_status_display_format html;
       # 可以配置权限
        allow 127.0.0.1；
        allow 192.168.9.0/24;
       #配置拒绝所有
       #  deny all;
    }

• 启动容器
  在tengine 容器内部执行命令可以看到已经加载vts模块

nginx -V

可以看到有如下模块，说明加入成功ngx_http_vhost_traffic_status_module

• 打开浏览器，访问地址，即可显示监控内容

附录[自定义tengine Dockerfile]

需要注意与Dockerfile同一目录下需要提前写好一个nginx.conf配置

使用命令

docker build -t your_docker_file  .
