Nginx
根據 URL 中的參數使用不同的 PHP 上游 - NGinx
我執行 Nginx 和 PHP-FPM。Nginx 在 www-data 下執行,PHP-FPM 作為每個網站的單獨使用者執行。我使用 Nginx FASTCGI 記憶體並使用 WordPress 的 Nginx Helper 外掛。不幸的是,由於使用者不同,我們不能在外掛中使用“Purge All”功能,因為 php 使用者無權訪問記憶體。
由於安全原因,更改權限不是一種選擇。
如果 URL 中存在以下參數,我想要做的是使用不同的 PHP-FPM 池。
nginx_helper_urls=all
我目前的 NGinx 配置如下:
upstream examplebackend { server unix:/var/run/php-fcgi-example.sock; } upstream cachedeletebackend { server unix:/var/run/php-fcgi-cachedelete.sock; } server { listen 80 default; server_name www.example.com; return 301 https://www.example.com$request_uri; } server { listen 80; server_name example.com; return 301 https://www.example.com$request_uri; } server { listen 443 ssl; server_name example.com; return 301 https://www.example.com$request_uri; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; } server { listen 443 ssl; ssl_protocols TLSv1.2 TLSv1.3; server_name www.example.com; ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; access_log /home/examplecom/logs/example.com.access.log; error_log /home/examplecom/logs/example.com.error.log; root /home/examplecom/public_html; index index.php; set $skip_cache 0; # POST requests and urls with a query string should always go to PHP if ($request_method = POST) { set $skip_cache 1; } if ($query_string != "") { set $skip_cache 1; } # Don't cache uris containing the following segments if ($request_uri ~* "/wp-admin/|/xmlrpc.php|wp-.*.php|/feed/|index.php|sitemap(_index)?.xml") { set $skip_cache 1; } # Don't use the cache for logged in users or recent commenters if ($http_cookie ~* "comment_author|wordpress_[a-f0-9]+|wp-postpass|wordpress_no_cache|wordpress_logged_in") { set $skip_cache 1; } location / { try_files $uri $uri/ /index.php?$args; } location ~ \.php$ { try_files $uri =404; include fastcgi_params; if ( $args ~ nginx_helper_urls=all ) { fastcgi_pass cachedeletebackend; } fastcgi_pass examplebackend; fastcgi_cache_bypass $skip_cache; fastcgi_no_cache $skip_cache; fastcgi_cache WORDPRESS; fastcgi_cache_valid 60m; } location ~ /purge(/.*) { fastcgi_cache_purge WORDPRESS "$scheme$request_method$host$1"; } location ~* ^.+\.(ogg|ogv|svg|svgz|eot|otf|woff|mp4|ttf|rss|atom|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|tar|mid|midi|wav|bmp|rtf)$ { access_log off; log_not_found off; expires max; } location = /robots.txt { access_log off; log_not_found off; } location ~ /\. { deny all; access_log off; log_not_found off; } }
不知道我哪裡出錯了,或者是否有可能。謝謝
這很可能發生,因為If 是 evil。
在 nginx 中,大部分
if
語句應該用map
feature 來實現。在您的情況下,首先定義
map
inhttp
級別:map $arg_nginx_helper_urls $backend { all cachedeletebackend; default examplebackend; }
然後,在 PHP
location
塊中使用:location ~ \.php$ { try_files $uri =404; include fastcgi_params; fastcgi_pass $backend; fastcgi_cache_bypass $skip_cache; fastcgi_no_cache $skip_cache; fastcgi_cache WORDPRESS; fastcgi_cache_valid 60m; }
該映射將
$backend
根據查詢參數值為變數分配一個nginx_helper_urls
值。預設情況下,examplebackend
使用。如果參數值為all
,則將cachedeletebackend
其分配給變數。
