nginx 部署vue 前后端分离遇到问题

记录：

vue项目 npm run build 打包。

会在项目根目录生成dist目录，此目录就是要部署到服务器的代码。

本人后端是springboot+maven  直接maven打jar包。

在服务器配置好运行环境，代码拷贝到服务器。

下载nginx，我这里用的是1.16.0版本。

下面就直接配置nginx：

找到conf目录下的nginx.conf。

下面内容：

#user  nobody;
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;

    server {
        listen       8888;#默认端口是80，如果端口没被占用可以不用修改
        server_name  localhost;

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

        location / {
			root E:/sqwyq/dist;
            try_files $uri $uri/ @router;#需要指向下面的@router否则会出现vue的路由在nginx中刷新出现404
            index  index.html index.htm;
        }
        #对应上面的@router，主要原因是路由的路径资源并不是一个真实的路径，所以无法找到具体的文件
        #因此需要rewrite到index.html中，然后交给路由在处理请求资源
        location @router {
            rewrite ^.*$ /index.html last;
        }

}

遇到问题点：

1.vue项目中的需要添加

2.nginx配置文件中后端配置的ip要写127.0.0.1  如下图：（写v4的ip会报一个错，我也没有明白为什么，反正写127.0.0.1就没问题）

总结：nginx就是先拦截在找location，也就是nginx的代理的作用。
