系统环境：Mac Pro—10.15.7版本

Nginx版本：1.19.6

一、安装Nginx

brew install nginx

1、安装完成

Nginx的配置文件目录：/usr/local/etc/nginx

Nginx的安装目录：/usr/local/Cellar/nginx

2、启动Nginx

brew services start nginx

3、问题

可能遇到的报错一：nginx: [error] open() "/usr/local/var/run/nginx.pid" failed (2: No such file or directory)

解决：原因是默认nginx主配置文件位置与你当前不一样。使用终端进入到Nginx安装位置，然后输入 【./nginx -h】 即可查看

 找到-e filename那一栏，将default后面的路径复制下来，然后使用命令指定nginx.conf文件的位置：

【./nginx -c /usr/local/etc/nginx/nginx.conf】，之后输入命令重新加载：【./nginx -s reload】即可。

二、修改Nginx配置文件

打开Nginx配置文件：/usr/local/etc/nginx/nginx.conf

需要修改3处，下面的配置文件中已添加注释，查看“注意”开头的说明

1. root后面的前端打包好的文件路径；
2. location后面的映射路径，该路径为服务端Swagger配置的pathMapping值；
3. proxy_pass后面的本机ip地址；

#user  nobody;
worker_processes  1;

#pid        logs/nginx.pid;
pid        /usr/local/Cellar/nginx/1.19.6/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;

    server {
        listen       80;
        server_name  localhost;
        charset utf-8;

        #access_log  logs/host.access.log  main;

        #注意：修改root后面的地址为你打包好的dist文件夹前端项目路径
        location / {
            root   xx/yy/zz/dist;
            try_files $uri $uri/ /index.html;
            index  index.html index.htm;
        }

        #注意：/prod-api/ 为你的服务端Swagger中配置的pathMapping属性值
        #注意：修改proxy_pass后面的地址为你部署机器的ip地址，切记端口号后面斜杠不要去掉【/】
        location /prod-api/ {
            proxy_set_header Host $http_host;
			proxy_set_header X-Real-IP $remote_addr;
			proxy_set_header REMOTE-HOST $remote_addr;
			proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
			proxy_pass http://0.0.0.0:8081/;

        #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;
        #}

        #省略.......
    }

    include servers/*;
}

配置好后输入命令重新加载【./nginx -s reload】。

之后在浏览器输入本机ip地址即可访问，注意：如果服务端的端口号为80开头，ip地址后面不加端口号。
