[Nginx] Nginx服务器中配置404错误页面时一些值得注意的地方

Instead of returning a 404 response code for a non-existent URL, websites that serve "soft 404s" return a 200 response code.

Soft 404s can occur as a result of configuration errors when an Error Document 404 is specified as an absolute path rather than a relative path.

vim /usr/local/nginx/conf/nginx.conf

vim /usr/local/nginx/conf/vhosts/slyar.com.nginx.conf

server {
#error_page 404 //www.slyar.com/404.html
error_page 404 /404.html;
}

/usr/local/nginx/sbin/nginx -s reload

curl -I //www.slyar.com/slyar
