nginx解析PHP頁面時沒法顯示出來,查看nginx日誌,報錯信息如上;

緣由:
在fastcgi_params文件(和nginx.conf文件在同一個目錄下)裏定義了許多與fastcgi程序相關的變量,當nginx經過fastcgi接口發送請求時它要去定義好的地方去解析相應的變量值,而後交給php去處理,很顯然,若是fastcgi獲取不了相應的值,那麼他就沒法把相應請求轉發給php程序,天然沒法解析。php
這個問題的關鍵在於"Primary script unknown」主腳本未知,也就是fastcgi程序沒法找到定義的要執行的腳本,默認的配置文件fastcgi_params定義的變量中並無$fastcgi_script_name這個變量,可是在fastcgi.conf裏定義了。因此咱們要麼包含這個fastcgi.conf文件,要麼把fastcgi_params裏的SCRIPT_FILENAME 構建成和fastcgi.conf裏的值同樣,加上$document_root參數(這個參數的值就表明站點目錄root那一行的值)。
解決方案1
在配置最後一行包含fastcgi.conf配置文件,結果以下html
1 location ~ \.php$ { 2 root html/wordpress; 3 fastcgi_pass 127.0.0.1:9000; 4 fastcgi_index index.php; 5 fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name; 6 include fastcgi_params; 7 include fastcgi.conf; 8 }
解決方案2
把fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;這一行,改成:fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;nginx
1 location ~ \.php$ { 2 root html/wordpress; 3 fastcgi_pass 127.0.0.1:9000; 4 fastcgi_index index.php; 5 fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; 6 include fastcgi_params; 7 }
