请问nginx如何配置前后端服务？

Question

我不太懂这块，谷歌了很多地方，终于把环境搭好了，但nginx配置这里不会弄……

我的环境是 centos7 php（Yaf）+ nginx + mysql

文件目录：
var/www/api/... 后端服务
var/www/html/...前端代码

nginx配置

server {
    listen       80;
    server_name  localhost;

    root   /var/www/html;
    index  index.html index.htm index.php;

    location ~ \.php$ {
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
        include        fastcgi_params;
    }
}

我现在有一个域名——比如www.demo.com
可以访问前端页面，但怎样访问后端服务呢？

Answer 1

后端配置一个子域名，前端直接调用子域名来访问后端服务

server {
    listen       80;
    server_name  www.demo.com;

    root   /var/www/html;
    index  index.html index.htm index.php;
}

server {
    listen       80;
    server_name  api.demo.com;

    root   /var/www/api;
    index  index.html index.htm index.php;

    location ~ \.php$ {
        fastcgi_pass   php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME /var/www/html$fastcgi_script_name;
        include        fastcgi_params;
    }
}

const domain = 'http://api.demo.com';
axios(`${domain}/test`);
