配置/folder的路径与/

Question

我有一个问题，运行/folder从不同的途径，而不是主要的网站。

该部分的nginx.conf如下所示：

        location ~ \.php$ {
            try_files               $uri = 404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_param       SCRIPT_FILENAME $request_filename;
            fastcgi_pass            unix:/var/run/php/php7.2-fpm.sock;
            fastcgi_index           index.php;
           include                 fastcgi_params;
            include                 fastcgi.conf;
    }


location ~ /folder {
        alias /srv/http/folder;
    try_files $uri $uri/ @folder;

    location ~ \.php$ {
                fastcgi_param SCRIPT_FILENAME $request_filename;
                fastcgi_pass   unix:/var/run/php/php7.2-fpm.sock;
                include        fastcgi.conf;
        }
}

location @folder {
    rewrite /folder/(.*)$ /folder/index.php?/$1 last;
}

在error.log中，我可以看到以下内容：

2020/06/03 09:05:26 [error] 25966#25966: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.21.2.46, server: example.com, request: "GET /folder/xxx_v6.15.11/Resources/images/redcaplogo.gif HTTP/1.1", upstream: "fastcgi://unix:/var/run/php/php7.2-fpm.sock:", host: "example.com"

有什么办法解决这个问题吗？

Regex位置从第一个匹配到最后，第一个找到的匹配由nginx处理。当您收到/folder/script.php请求时，它将由第一个location块处理。试着换掉这两个地点。另外，为什么在第二个位置块中不包括fastcgi_params？

更新

我做了一些调试，让我们看看您的代码(假设位置块已经被交换)：

location ~ /folder {
    alias /srv/http/folder;
    try_files $uri $uri/ @folder;

    location ~ \.php$ {
        fastcgi_param  SCRIPT_FILENAME $request_filename;
        fastcgi_pass   unix:/var/run/php/php7.2-fpm.sock;
        include        fastcgi_params;
        include        fastcgi.conf;
    }
}

location ~ \.php$ {
    try_files               $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_param           SCRIPT_FILENAME $request_filename;
    fastcgi_pass            unix:/var/run/php/php7.2-fpm.sock;
    fastcgi_index           index.php;
    include                 fastcgi_params;
    include                 fastcgi.conf;
}

location @folder {
    rewrite /folder/(.*)$ /folder/index.php?/$1 last;
}

如果我们得到一个请求/folder/some/path (并且folder中没有some/path文件或目录)，那么嵌套位置内部的nginx变量将有以下值：

• $request_filename：空字符串(在folder目录中没有真正的文件或文件夹/some/path )；
• $uri：/folder/check.php；
• $document_root：/srv/http/folder.

如果我们得到一个请求/folder/some/path/script.php (并且有一个真正的具有此名称的PHP脚本)，那么在嵌套位置内部的nginx变量中将有以下值：

• $request_filename：/srv/http/folder/some/path/script.php；
• $uri：/folder/some/path/check.php；
• $document_root：/srv/http/folder.

此外，当您从文件夹(例如/folder/some/path/static.css )获得静态资源请求时，try_files $uri ...指令将在/srv/http/folder目录中搜索folder/some/path/static.css文件，这将导致检查/srv/http/folder/folder/some/path/static.css文件的存在。

在folder目录中获取文件子路径的可能解决方案之一是：

location ~ ^/folder(?<subpath>.*) {
    alias /srv/http/folder;
    try_files $subpath $subpath/ @folder;

    location ~ \.php$ {
        fastcgi_param  SCRIPT_FILENAME $document_root$subpath;
        fastcgi_pass   unix:/var/run/php/php7.2-fpm.sock;
        include        fastcgi_params;
        include        fastcgi.conf;
    }
}

location ~ \.php$ {
    try_files               $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_param           SCRIPT_FILENAME $request_filename;
    fastcgi_pass            unix:/var/run/php/php7.2-fpm.sock;
    fastcgi_index           index.php;
    include                 fastcgi_params;
    include                 fastcgi.conf;
}

location @folder {
    rewrite ^/folder/(.*)$ /folder/index.php?/$1 last;
}

如果您的实际folder目录名称与/folder URI前缀相同，则可以简化此操作：

location ~ ^/folder {
    root /srv/http;
    try_files $uri $uri/ @folder;

    location ~ \.php$ {
        fastcgi_param  SCRIPT_FILENAME $document_root$uri;
        fastcgi_pass   unix:/var/run/php/php7.2-fpm.sock;
        include        fastcgi_params;
        include        fastcgi.conf;
    }
}

...

作为nginx文档州

当位置与指令值的最后一部分匹配时： 位置/图像/{别名/数据/w3/图像/；} 最好使用根指令，而不是： 位置/图像/{ root /data/w3；}
