Nginx 重定向循环

我正在尝试将网站从一台服务器转移到另一台服务器。我通常使用 apache，但这个项目使用 nginx 和 Ultimate SEO 进行 url 修改。我使用相同的 nginx 配置文件，但最终出现重定向循环错误。以下是 sites-available 中默认文件的内容：

# You may add here your
# server {
#   ...
# }
# statements for each of your virtual hosts

server {
    listen   80 default;
    server_name  mysitehere.com;

    access_log  /var/log/nginx/mysitehere.access.log;
       #fastcgi_param  DOCUMENT_ROOT     /site/public_html/;
    location / {
        root   /site/public_html/;
        index  index.php index.html index.htm;


#       rewrite ^/(.*) http://mysitehere.com/$1 permanent;


        #rewrite ^/index.php?main_page=shopping_cart$ http://mysitehere.com/index.php?main_page=shopping_cart last;

        if ($host != 'mysitehere.com') {
            rewrite ^/(.*)$ http://mysitehere.com/$1 last;
        }

        if ($host = 'mysitehere.com') {
            rewrite ^/(.*)$ http://mysitehere.com/$1 last;
        }

        # From Ultimate SEO URLs
        rewrite ^/(.*)-blog-(.*).html$ /index.php?main_page=blogread last;
        rewrite ^/(.*)-se-(.*).html$ /index.php?main_page=readarticle last;
        rewrite ^/(.*)-ca-(.*).html$ /index.php?main_page=readarticle last;
        rewrite ^/blog.html$ /index.php?main_page=blog last;
        rewrite ^/(.*)-p-(.*).html$ /index.php?main_page=product_info&products_id=$2&$query_string last;
        rewrite ^/(.*)-ri-(.*).html$ /index.php?main_page=document_general_info&products_id=$2&$query_string last;
        rewrite ^/(.*)-c-(.*).html$ /index.php?main_page=index&cPath=$2&$query_string} last;
        rewrite ^/(.*)-m-([0-9]+).html$ /index.php?main_page=index&manufacturers_id=$2&$query_string last;
        rewrite ^/(.*)-pi-([0-9]+).html$ /index.php?main_page=popup_image&pID=$2&$query_string last;
        rewrite ^/(.*)-pr-([0-9]+).html$ /index.php?main_page=product_reviews&products_id=$2&$query_string last;
        rewrite ^/(.*)-pri-([0-9]+).html$ /index.php?main_page=product_reviews_info&products_id=$2&$query_string last;

        # For Open Operations Info Manager
        rewrite ^/(.*)-i-([0-9]+).html$ /index.php?main_page=info_manager&pages_id=$2&$query_string last;

        # For dreamscape's News & Articles Manager
        rewrite ^/news/?$ /index.php?main_page=news&$query_string last;
        rewrite ^/news/rss.xml$ /index.php?main_page=news_rss&$query_string last;
        rewrite ^/news/archive/?$ /index.php?main_page=news_archive&$query_string last;
        rewrite '^/news/([0-9]{4})-([0-9]{2})-([0-9]{2}).html$ /index.php?main_page=news&date=$1-$2-$3&$query_string' last;
        rewrite '^/news/archive/([0-9]{4})-([0-9]{2}).html$ /index.php?main_page=news_archive&date=$1-$2&$query_string' last;
        rewrite ^/news/(.*)-a-([0-9]+)-comments.html$ /index.php?main_page=news_comments&article_id=$2&$query_string last;
        rewrite ^/news/(.*)-a-([0-9]+).html$ /index.php?main_page=news_article&article_id=$2&$query_string last;

        # All other pages
        if (!-f $request_filename) {
         rewrite ^/(.*).html$ /index.php?main_page=$1&$query_string last;
        }

        location ~ /\. {
                deny        all;
                }



    }

        location ~* ^.+\.(jpg|jpeg|gif|png|ico|css|js|bmp)$ { 
        root   /site/public_html;
        rewrite ^/min/([a-z]=.*) /min/index.php?$1 last;
        rewrite ^(.*?)\.v-([^\.]+)\.(js|css)$ $1.$3;
        access_log off;
        expires max;
        }

     location ~* \.php$ {
        fastcgi_pass        unix:/tmp/php-fpm.sock;
        fastcgi_index       index.php;
            fastcgi_param       DOCUMENT_ROOT     /site/public_html;
        fastcgi_param       SCRIPT_FILENAME  /site/public_html;
        include             fastcgi_params;
    }    

       # HTTPS
    error_page  404  /index.php?main_page=page_not_found;


}

我用“mysitehere”替换了实际的 URL，但除此之外，它还是一样。我尝试阅读有关此事的其他帖子，但无法确定是什么导致了此特定文件的错误。有人知道是什么原因造成的吗？

我认为你的问题在于这个配置部分：

    if ($host = 'mysitehere.com') {
        rewrite ^/(.*)$ http://mysitehere.com/$1 last;
    }

请注意，这基本上是将 mysitehere.com 上的任何 URL 重写为其自身，最后一个指令停止进一步处理。由于重写的 URL 以 http:// 开头，因此它指示 Nginx 执行外部 301 重定向，而不是内部重写 URL 并将页面作为另一个 URL 提供。我会完全删除此部分。

如果你还没有这样做，请查看Nginx 重写文档了解详细信息；阅读起来并不复杂。
