NGINX：配置多个根或索引的位置

Question

我想为phpinfo.php文件配置一个位置，/phpinfo并为 phpPgAdmin 配置另一个位置/phppgadmin。我的服务器根目录位于/usr/share/nginx/html/，在那里我有一个index.html和phpinfo.php文件，phpPgAdmin 位于 ，/usr/share/phppgadmin其index.php文件位于 内。

这是我的default.conf文件：

server {
    listen       80;
    server_name  localhost;
    root /usr/share/nginx/html;
    index index.html index.htm index.php;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/run/php/php7.3-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }

    location /phpinfo {
        index phpinfo.php;
    }

    location /phppgadmin {
        alias /usr/share/phppgadmin;
    }
}

我为每个位置都设置了一个位置块，但都不起作用。

基本上我想要的是将所有这些配置为转到我的 php 信息http://localhost/phpinfo和我的 phpPgAdmin 数据库管理器http://localhost/phppgadmin。

Answer 1

让我们首先来看这个最小的工作示例：

server {
    listen   80;
    server_name  test.sc;
    root /usr/share/nginx/html;
    index index.html index.htm index.php;

    location /phpinfo {
        alias /usr/share/phppgadmin/;
        index phpinfo.php;

    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }

}

这里的问题是，通过使用

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

FPM 传递 /usr/share/nginx/html/phpinfo.php 进行处理，因为已定义带有“root”指令的 /usr/share/nginx/html。这将是“未指定输入文件。”错误。

如何操作：

server {
    listen   80;
    server_name  test.sc;
    root /usr/share/nginx/html;
    index index.html index.htm index.php;

    location /phpinfo {
        alias /usr/share/phppgadmin/;
        index phpinfo.php;

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

    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }

}

这样，/usr/share/phppgadmin/ 目录中的 php 文件将被单独处理，您甚至可以在 /usr/share/phppgadmin/ 上下文中为这些文件分配不同的 FPM 池。其他所有内容将使用下面的默认值进行处理。Nginx 仅限于此行为，因为将使用第一个正则表达式匹配块，它不会继续尝试任何进一步的操作或使用多个位置块。

现在您可以根据需要扩展配置：

server {
    listen   80;
    server_name  test.sc;
    root /usr/share/nginx/html;
    index index.html index.htm index.php;

    location /phpinfo {
        alias /usr/share/phppgadmin/;
        index phpinfo.php;

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

    }

    location /phppgadmin {
        alias /usr/share/phppgadmin;
        index index.php;

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

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }

}

此外，您可以通过重复使用某些部分来缩短此配置：

在 /etc/nginx/php_settings 中：

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

/etc/nginx/sites-enabled/000.conf：

server {
    listen   80;
    server_name  test.sc;
    root /usr/share/nginx/html;
    index index.html index.htm index.php;

    location /phpinfo {
        alias /usr/share/phppgadmin/;
        index phpinfo.php;

        include php_settings;
    }

    location /phppgadmin {
        alias /usr/share/phppgadmin;
        index index.php;

        include php_settings;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }

}
