nginx和fastcgi的两个文档根

Question

我在一个docker环境中使用nginx和php，它对单个应用程序工作正常。现在我想开发一个基于yii2/php的应用程序作为后端和angular作为前端，所以我需要一个webserver服务于客户端，另一个服务于API后端。目录结构如下所示：

/var/www/html/ $ tree -L 3 
. 
├── client 
│   ├── dist 
│   │   ├── 0.chunk.js 
│   │   ├── 0.chunk.js.map 
│   │   ├── assets 
│   │   ├── index.html 
│   │   ├── ... 
│   ├── e2e 
│   │   ├── ... 
│   ├── node_modules 
│   │   ├── ... 
├── docker 
│   ├── mysql 
│   │   ├── Dockerfile 
│   │   └── my.cnf 
│   ├── nginx 
│   │   ├── Dockerfile 
│   │   └── default.conf 
│   └── php7 
│    └── Dockerfile 
├── docker-compose.yml 
└── server 
    ├── api 
    │   ├── common 
    │   ├── config 
    │   ├── modules 
    │   └── web 
    │ │   └── index.php 
    ├── common 
    ├── composer.json 
    ├── console 
    └── vendor 

的前端应用程序位于`在/ var/www/html等/客户/距离/，Nginx的配置如下所示：

server { 
    listen 80 default_server; 
    root /var/www/html/client/dist/; 
    index index.html index.php; 

    charset utf-8; 

    location/{ 
      # Redirect everything that isn't a real file to index.php 
      try_files $uri $uri/ /index.php$is_args$args; 
     } 

    location /api { 
     root /var/www/html/server/api/web/; 
     try_files $uri $uri/ /index.php$is_args$args; 
    } 

    location = /favicon.ico { access_log off; log_not_found off; } 
    location = /robots.txt { access_log off; log_not_found off; } 

    sendfile off; 

    client_max_body_size 100m; 

    location ~ \.php$ { 
     fastcgi_split_path_info ^(.+\.php)(/.+)$; 
     fastcgi_pass php:9000; 
     fastcgi_index index.php; 
     include fastcgi_params; 
     fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
     fastcgi_intercept_errors off; 
     fastcgi_buffer_size 16k; 
     fastcgi_buffers 4 16k; 
     fastcgi_read_timeout 300s; 
    } 

    location ~ /\.ht { 
     deny all; 
    } 
} 

使用该配置，前端工作（URL：/），但是API不。我需要的是：

请求 “/”：从/var/www/html/client/dist/ 请求 “/ API” 服务的角度应用：使用来自/var/www/html/server/api/web/

index.php如何配置呢？谢谢。

//编辑：新的配置文件：

server { 
    listen 80 default_server; 
    root /var/www/html/client/dist/; 
    index index.html; 

    charset utf-8; 

    location ~ ^/api(.*) { 
     alias /var/www/html/server/api/web/; 

     # Redirect everything that isn't a real file to index.php 
     try_files $uri $uri/ /index.php$1$args; 
     index index.php; 

     location ~ \.php$ { 
      fastcgi_split_path_info ^(.+\.php)(/.+)$; 
      fastcgi_pass php:9000; 
      fastcgi_index index.php; 
      include fastcgi_params; 
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 
      fastcgi_intercept_errors off; 
      fastcgi_buffer_size 16k; 
      fastcgi_buffers 4 16k; 
      fastcgi_read_timeout 300s; 
     } 

     location ~ /\.ht { 
      deny all; 
     } 
    } 

    location = /favicon.ico { access_log off; log_not_found off; } 
    location = /robots.txt { access_log off; log_not_found off; } 

    access_log off; 
    error_log /var/log/nginx/error.log error; 

    sendfile off; 

    client_max_body_size 100m; 
} 

调用http://localhost/api/v1/users应该转用V1 /用户作为参数传递给/var/www/html/server/api/web/index.php（或然Yii2处理漂亮的URL），但是返回404找不到。

错误日志显示了该消息，所以它看起来像别名指令不发生作用：

2017/07/11 16:51:57 [error] 5#5: *1 open() "/var/www/html/client/dist/index.php" failed (2: No such file or directory), client: 172.17.0.1, server: , request: "GET /api/v1/users HTTP/1.1", host: "localhost"

不清楚自己需要重写漂亮的URI来什么，但你需要使用的URI index.php其中包括/api前缀。

alias directive最适合prefix location，否则您将需要使用捕获的变量构建路径。

例如：

location ^~ /api/ { 
    alias /var/www/html/server/api/web/; 

    index index.php; 

    if (!-e $request_filename) { 
     rewrite ^/api(.*) /api/index.php?uri=$1 last; 
    } 

    location ~ \.php$ { 
     if (!-f $request_filename) { return 404; } 

     fastcgi_pass php:9000; 
     include fastcgi_params; 
     fastcgi_param SCRIPT_FILENAME $request_filename; 
     fastcgi_intercept_errors off; 
     fastcgi_buffer_size 16k; 
     fastcgi_buffers 4 16k; 
     fastcgi_read_timeout 300s; 
    } 

    location ~ /\.ht { 
     deny all; 
    } 
}
