与本应用相关的nginx配置文件放在当前部署文件夹下_nginx-1.20.1配置文件放到其他文件夹中-优快云博客

本文介绍了如何在current文件夹下创建服务相关的nginx配置文件，并通过软链接将其包含到服务器的默认配置文件夹中，以确保配置生效。步骤包括新建nginx.conf文件，检查nginx语法，以及设置软链接并重启nginx进行验证。

（1）首先在current文件夹下新建服务有关的nginx配置文件nginx.conf

upstream news_server {
  server unix:/tmp/unicorn.news.sock fail_timeout=0;
}

server {
  listen 8888;
  access_log /opt/app/ruby/news/current/log/nginx.access.log;
  error_log /opt/app/ruby/news/current/log/nginx.error.log;

  client_max_body_size 4G; 

  keepalive_timeout 5;

  root /opt/app/ruby/news/current/public;

  location ^~ /assets/ {
    gzip on; 
    expires max;
    add_header Cache-Control public;
  }

  try_files $uri/index.html $uri @unicorn;
  location @unicorn {
    proxy_redirect  off;
    proxy_set_header  Host  $http_host;

    proxy_set_header  X-Forwarded-For  $proxy_add_x_forwarded_for;
    proxy_set_header  X-Real-IP  $remote_addr;
    proxy_pass http://news_server;
  }
  error_page 500 502 503 504 /500.html;
  location = /500.html {
    root /opt/app/ruby/news/current/public;
  }
}

（2）在服务器检查下nginx语法，顺便查看位置

[root@localhost opt]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

查看nginx的配置

vim /etc/nginx/nginx.conf

找到默认conf配置文件放的位置

user  nginx;
worker_processes  8;

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


events {
    worker_connections  1024;
}


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

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

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

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

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

从最后一句话中我们可以得知，所有/etc/nginx/conf.d/下的后缀名为.conf的配置文件都会被include进来，

所以需要做一个软链接，将我们应用部署目录下的nginx配置文件链到这个文件夹下，重启检测下语法并重启nginx

[root@localhost opt]# ln -s /opt/app/ruby/news/current/config/nginx.conf /etc/nginx/conf.d/new.conf
[root@localhost opt]# ll /etc/nginx/conf.d/

lrwxrwxrwx 1 root root   44 9月  18 10:56 new.conf -> /opt/app/ruby/news/current/config/nginx.conf
