使用Nginx要在同一個域名下配置多個專案有兩種方式：

1. nginx按不同的目錄分發給不同的專案
2. 啟用二級域名，不同的專案分配不同的二級域名

1.nginx按不同的目錄分發給不同的專案：

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;
    }
}
 

這裡配置了三個專案：

• http://example.com/project1路徑分發到http://localhost:8081
• http://example.com/project2路徑分發到http://localhost:8082
• 其他路徑分發到http://localhost:8080

2.啟用二級域名，不同的專案分配不同的二級域名

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：這三個專案屬於不同的域名，專案之間通過http訪問會存在跨域問題。
