Nginx配置多个vue前端项目+后端项目

我在之前已经使用docker+nginx部署一个vue项目了，大概是这样的

# conf.d default.conf
server {
    listen       80;
    listen  [::]:80;
    server_name  http://localhost;

    #charset koi8-r;
    #access_log  /var/log/nginx/host.access.log  main;

    location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

    #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   /usr/share/nginx/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;
    #}
}

接着，我想用一个nginx部署多个项目

• 1 先把之前的项目的publicPath修改一下

• 2 npm run build,再将dist文件夹的东西上传到/usr/share/nginx/html/project1下

• 3 再在default.conf中添加如下配置

    location = /project1 {
         root   /usr/share/nginx/html/project1;
         try_files $uri $uri/ /project1/index.html;
         index  index.html index.htm;
     }

再配置一个后端项目

首先试了以下直接用路径来配置，貌似不行

location /N-chat {
         proxy_pass       http://localhost:3000;               #映射到代理服务器，可以是ip加端口,   或url 
         proxy_set_header Host      $host;
         proxy_set_header X-Real-IP $remote_addr;
         proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     }

直接报错，找不到路径

之后试了监听不同的端口来实现,添加了如下的配置

server {
        listen       3000; 
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            proxy_pass http://localhost:3000;
        }
 }
