Nginx添加nginx-module-vts监控

本文已参与「新人创作礼」活动，一起开启掘金创作之路。

一、版本说明

（1）系统：CentOS 7.3

（2）Nginx：1.15.7 nginx.org/download/

（3）nginx-module-vts：v0.1.18 github.com/vozlt/nginx…

二、安装nginx-module-vts

（1）解压安装

unzip nginx-module-vts-master.zip
mv nginx-module-vts-master /usr/local/

三、编译安装Nginx

（1）安装依赖环境（本文所使用yum源为CentOS7.3镜像本地yum源）

yum -y install gcc gcc-c++ pcre pcre-devel zlib zlib-devel openssl openssl-devel

（2）编译安装nginx

编译时添加监控组件nginx-module-vts，其他默认即可

tar -xvf nginx-1.15.7.tar.gz
cd nginx-1.15.7
./configure --add-module=/usr/local/nginx-module-vts-master/
make && make install

（3）编辑配置文件

vim /usr/local/nginx/conf/nginx.conf

替换为如下配置，主要是修改默认日志文件格式，添加压缩配置，添加监控配置，具体可根据自己的需求修改

user  nobody;
worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    vhost_traffic_status_zone;

    log_format main '{ "@timestamp": "$time_local", '
                         '"@fields": { '
                         '"uri":"$request_uri",'
                         '"url":"$uri",'
                         '"upstream_addr":"$upstream_addr",'
                         '"remote_addr": "$remote_addr", '
                         '"remote_user": "$remote_user", '
                         '"body_bytes_sent": "$body_bytes_sent", '
                         '"host":"$host",'
                         '"server_addr":"$server_addr",'
                         '"request_time": "$request_time", '
                         '"request_time":"$request_time",'
                         '"status":"$status",'
                         '"request": "$request", '
                         '"request_method": "$request_method", '
                         '"size":$body_bytes_sent,'
                         '"upstream_time":"$upstream_response_time"'
                         '"http_referrer": "$http_referer", '
                         '"body_bytes_sent":"$body_bytes_sent", '
                         '"http_x_forwarded_for": "$http_x_forwarded_for", '
                         '"http_user_agent": "$http_user_agent" } }';

    sendfile        on;

    keepalive_timeout  65;

    gzip  on;
    gzip_min_length   1k;
    gzip_buffers      4 16k;
    gzip_http_version 1.0;
    gzip_comp_level   3;
    gzip_types        text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript application/json application/javascript;
    gzip_vary         on;
    proxy_http_version 1.1;
    proxy_set_header Connection "";
    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;
            index  index.html index.htm;
        }
	location /status {
		vhost_traffic_status_display;
		vhost_traffic_status_display_format html;
        }
    }
}

（4）启动测试

默认nginx安装目录为/usr/local/nginx/，相关目录都在这个目录下

• 启动nginx

/usr/local/nginx/sbin/nginx

• 测试
  浏览器输入IP+80端口，可打开nginx默认页面
  
  浏览器输入“IP:80/status”可打开监控页面
  

四、开机自启

将“/usr/local/nginx/sbin/nginx”命令加入“/etc/rc.d/rc.local”文件并添加权限即可

chmod +x /etc/rc.d/rc.local
