nginx 无法使用不同的根位置加载 wordpress 子文件夹

Question

我们在不同路径的根域的子文件夹中安装了 wordpress，即使在该位置使用 root，wordpress 安装仍然加载域站点的根。

server {
  listen              80;
  server_name         domain.com;
  return              301 https://$server_name$request_uri;
}

server {
  listen              443 ssl;
  server_name         domain.com;

  ssl                 on;
  #ssl_certificate     /var/www/certs/star.domain.com.cert;
  #ssl_certificate_key /var/www/certs/star.domain.com.key;
  ssl_certificate      /var/www/certs/cert_chain.crt;
  ssl_certificate_key  /var/www/certs/__domain_com.key;
  ssl_protocols       SSLv3 TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers         ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM;

  return              301 https://www.$server_name$request_uri;
}

server {
  ## Default Server Settings
  include             /etc/nginx/basic.conf;

  listen              443 ssl;
  server_name         www.domain.com;

  access_log          /var/log/nginx/domain.access.log;
  error_log           /var/log/nginx/domain.error.log;

  root                /var/www/domain/current;
  index               index.php index.html;

  ssl                 on;
  #ssl_certificate     /var/www/certs/star.domain.com.cert;
  #ssl_certificate_key /var/www/certs/star.domain.com.key;
  ssl_certificate      /var/www/certs/cert_chain.crt;
  ssl_certificate_key  /var/www/certs/__domain_com.key;
  ssl_protocols       SSLv3 TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers         ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:+MEDIUM;

  error_page          404 /index.php;

  location / {
    try_files $uri $uri/ $uri.php?$query_string;
  }

location /blog {
    root /var/www/;
    try_files $uri $uri/ /blog/index.php?q=$request_uri;
}

location ~ /blog/.+\.php$ {
  try_files $uri $uri/ /blog/index.php?q=$request_uri =404;
  include       /etc/nginx/fastcgi_params.conf;
  fastcgi_pass  127.0.0.1:9000;
  fastcgi_index index.php;
}

}

这应该根据 https://www.nginx.com/resources/wiki/start/topics/tutorials/config_pitfalls/#root-inside-location-block

这是对域根目录的 curl 请求：

和访问日志：

现在是子文件夹：

所以你可以看到 404，这是有道理的，但我不知道为什么

Answer 1

您root的location ~ /blog/.+\.php$块中缺少一个语句。但是，如果嵌套位置块，您可能会发现更容易阅读：

location ^~ /blog {
    root /var/www/;
    try_files $uri $uri/ /blog/index.php?q=$request_uri;

    location ~ \.php$ {
        try_files $uri =404;
        include       /etc/nginx/fastcgi_params.conf;
        fastcgi_pass  127.0.0.1:9000;
    }
}
