使用Nginx为Web项目设置反向代理

下载Nginx: http://nginx.org/en/download.html
Mainline version 为开发版
Stable version 为最新稳定版
Legacy versions 为遗留的老版本的稳定版
这边下载的是 Stable 版本的 nginx/Windows-1.18.0，下载后解压，conf / nginx.conf 是 nginx 的默认配置文件。配置以及解释说明如下：

#运行用户
#user  nobody;

#启动进程,通常设置成和cpu的数量相等
worker_processes  1;

#全局错误日志
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#PID文件，记录当前启动的nginx的进程ID
#pid        logs/nginx.pid;


#工作模式及连接数上限
events {
    #单个后台worker process进程的最大并发链接数
    worker_connections  1024; 
}

#设定http服务器，利用它的反向代理功能提供负载均衡支持
http {
    #设定mime类型(邮件支持类型),类型由mime.types文件定义
    include       mime.types;
    default_type  application/octet-stream;

    #设定日志
    #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;

    #连接超时时间
    keepalive_timeout  65;

    #gzip压缩开关
    #gzip  on;

    #HTTP服务器
    server {
        #监听80端口，80端口是知名端口号，用于HTTP协议
        listen       80;
        
        #定义监听的域名
        server_name  localhost;

        #编码格式
        charset utf-8;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://127.0.0.1:8080;
            root   html;
            index  index.html index.htm;
        }

        #错误处理页面
        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

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


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

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

}

先启动web项目，确认proxy_pass中的url能访问到项目主页面，然后启动Nginx，访问localhost或者localhost:80都一样，直接映射到web项目的主页上了。

项目部署的地址端口

访问localhost
