nginx 转发 由于php语法错误 导致的 50x

server {
        listen 8008;
        root /root/php-test;
        index index.php index.html index.htm;

location ~ \.php {
            #fastcgi_pass unix:/tmp/php/php-fpm.sock;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index /index.php;
            fastcgi_split_path_info  ^(.+\.php)(/.+)$;
            fastcgi_param PATH_INFO  $fastcgi_path_info;
            fastcgi_param PATH_TRANSLATED $document_root$fastcgi_path_info;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
            include /usr/local/openresty/nginx/conf/fastcgi.conf;
        }
        location / {
            try_files $uri $uri/ /index.php?$query_string;
        }

fastcgi_intercept_errors on;

error_page   500 502 503 504 =200  /50x.php;
        location = /50x.html {
            root   /root/php-test;
        }

location ~ /\.ht {
            deny all;
        }
    }

重点：

fastcgi_intercept_errors on;

error_page   500 502 503 504 =200  /50x.php;
        location = /50x.html {
            root   /root/php-test;
        }

将 /root/php-test/50x.php 返回想要的结果。
