Nginx配置文件详解

如果我们的域名都配置到nginx.conf中，这样文件会很乱, 影响管理和阅读.所以nginx的include支持文件拆分出来,分成不同的配置文件
本文讲解通过主子配置的方式来实现Nginx的相关配置

切换路径，编辑主配置文件

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

主要修改的内容包括: 修改用户、修改服务端口、删除默认服务等

后续所有的服务都在子配置文件中进行配置

user  root; 
worker_processes  1; 

#error_log  logs/error.log; 
#error_log  logs/error.log  notice; 
#error_log  logs/error.log  info; 

#pid        logs/nginx.pid; 

events { 
    worker_connections  1024; 
} 

http { 
    include       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  logs/access.log  main; 

    sendfile        on; 
    #tcp_nopush     on; 

    #keepalive_timeout  0; 
    keepalive_timeout  65; 

    #gzip  on; 
    include /usr/local/nginx/conf/conf.d/*.conf; 

    #gzip  on;
    server {
        listen       80;
        server_name  localhost;

        location / {
            root   html;
            index  index.html index.htm;
        }
    }
}

创建存放虚拟主机的目录分别写入每台虚拟主机的配置

mkdir conf.d
vim test.conf

编写子配置文件test.conf文件内容

server { 
    listen 8080; 
    server_name a.b.com; 
    charset utf-8; 

    location / { 
        root /home/project/test/dist; 
        try_files $uri $uri/ /index.html last; 
        index index.html; 
    } 

    location /api/ { 
        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://127.0.0.1:8000/; 
    } 
}

重启nginx

至此配置完成
