一.访问指定域名的web服务器路径不存在时直接向用户报错
1>.编辑主配置文件
[[email protected] ~]# cat /yinzhengjie/softwares/nginx/conf/nginx.conf

2>.编辑子配置文件
[[email protected] ~]# cat /yinzhengjie/softwares/nginx/conf.d/node101_yinzhengjie_org.cn.conf
server {
listen 80;
listen 443 ssl;
server_name node101.yinzhengjie.org.cn;
location / {

3>.创建测试数据
[[email protected] ~]# mkdir -pv /yinzhengjie/data/web/nginx/{static,images} mkdir: created directory ‘/yinzhengjie/data/web/nginx’ mkdir: created directory ‘/yinzhengjie/data/web/nginx/static’ mkdir: created directory ‘/yinzhengjie/data/web/nginx/images’ [[email protected] ~]# [[email protected] ~]# mkdir -pv /yinzhengjie/data/web/nginx/images/jd mkdir: created directory ‘/yinzhengjie/data/web/nginx/images/jd’ [[email protected] ~]# [[email protected] ~]# wget https://www.jd.com/favicon.ico -O /yinzhengjie/data/web/nginx/images/jd/favicon.ico --2019-12-24 15:15:42-- https://www.jd.com/favicon.ico Resolving www.jd.com (www.jd.com)... 220.194.105.131, 2408:8710:20:1140:8000::3 Connecting to www.jd.com (www.jd.com)|220.194.105.131|:443... connected.

4>.启动nginx
[[email protected] ~]# ss -ntl

LISTEN 0 128 :::22 :::*
[[email protected] ~]#
[[email protected] ~]# nginx

5>.浏览器访问"https://node101.yinzhengjie.org.cn/"首页
6>.浏览器访问一个不存在的路径,例如"https://node101.yinzhengjie.org.cn/login/",结果直接向用户抛出404
二.访问指定域名的web服务器路径不存在时跳转到首页
1>.编辑子配置文件
[[email protected] ~]# cat /yinzhengjie/softwares/nginx/conf.d/node101_yinzhengjie_org.cn.conf
server {
listen 80;
listen 443 ssl;
server_name node101.yinzhengjie.org.cn;
location / {
root /yinzhengjie/data/web/nginx/static;
index index.html;
if ( !-f $request_filename ){
rewrite (.*) https://node101.yinzhengjie.org.cn/index.html;
}
}
location = /favicon.ico {
root /yinzhengjie/data/web/nginx/images/jd;
}
}
[[email protected] ~]#
[[email protected] ~]# nginx -t
nginx: the configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /yinzhengjie/softwares/nginx/conf/nginx.conf test is successful
[[email protected] ~]#
[[email protected] ~]#
2>.重新加载配置文件
[[email protected] ~]# ps -ef | grep nginx | grep -v grep
root 24396 1 0 15:17 ? 00:00:00 nginx: master process nginx
nginx 24397 24396 0 15:17 ? 00:00:00 nginx: worker process

nginx 24400 24396 0 15:17 ? 00:00:00 nginx: worker process
[[email protected] ~]#
[[email protected] ~]# nginx -s reload
