Nginx配置404页面-码农笔记

为什么要定义404页面？

配置404页面可以增加网站的友好程度，进而留住用户。因此，每个网站都应该定义自己的404页面。Nginx配置404页面很简单，只需如下几步：

一、创建自己的404.html页面

二、修改nginx.conf，在http区加入
fastcgi_intercept_errors on;

三、修改nginx.conf，在server区加入
error_page 404 = /404.html

四、测试nginx.conf
/opt/nginx/sbin/nginx –t

如果正确会显示如下信息
the configuration file /opt/nginx/conf/nginx.conf syntax is ok
configuration file /opt/nginx/conf/nginx.conf test is successful
kill -HUP cat /opt/nginx/nginx.pid
