Nginx同一个域名配置多个项目

使用Nginx要在同一个域名下配置多个项目有两种方式：

1. nginx按不同的目录分发给不同的项目
2. 启用二级域名，不同的项目分配不同的二级域名

1.nginx按不同的目录分发给不同的项目：

server {
    listen    80;
    server_name example.com;

    location ^~ /project1 {
        proxy_pass     http://localhost:8081;
        proxy_set_header  Host       $host;
        proxy_set_header  X-Real-IP    $remote_addr;
        proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location ^~ /project2 {
        proxy_pass     http://localhost:8082;
        proxy_set_header  Host       $host;
        proxy_set_header  X-Real-IP    $remote_addr;
        proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    location / {
       proxy_pass     http://localhost:8080;
       proxy_set_header  Host       $host;
       proxy_set_header  X-Real-IP    $remote_addr;
       proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

这里配置了三个项目：

• http://example.com/project1路径分发到http://localhost:8081
• http://example.com/project2路径分发到http://localhost:8082
• 其他路径分发到http://localhost:8080

2.启用二级域名，不同的项目分配不同的二级域名

server {
    listen    80;
    server_name example.com;
    location / {
       proxy_pass     http://localhost:8080;
       proxy_set_header  Host       $host;
       proxy_set_header  X-Real-IP    $remote_addr;
       proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

project1

server {
    listen    80;
    server_name project1.example.com;
    location / {
       proxy_pass     http://localhost:8081;
       proxy_set_header  Host       $host;
       proxy_set_header  X-Real-IP    $remote_addr;
       proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

project2

server {
    listen    80;
    server_name project2.example.com;
    location / {
       proxy_pass     http://localhost:8082;
       proxy_set_header  Host       $host;
       proxy_set_header  X-Real-IP    $remote_addr;
       proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

注意：这三个项目属于不同的域名，项目之间通过http访问会存在跨域问题。
