一.訪問指定域名的web服務器路徑不存在時直接向用戶報錯
1>.編輯主配置文件
[root@node101.yinzhengjie.org.cn ~]# cat /yinzhengjie/softwares/nginx/conf/nginx.conf
worker_processes 4;
worker_cpu_affinity 00000001 00000010 00000100 00001000;

use epoll;
accept_mutex on;
multi_accept on;
}
http {

include /yinzhengjie/softwares/nginx/conf.d/*.conf;
}
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# 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
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]#
2>.編輯子配置文件
[root@node101.yinzhengjie.org.cn ~]# 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;
}
location = /favicon.ico {
root /yinzhengjie/data/web/nginx/images/jd;
}
}
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# 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
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]#
3>.創建測試數據
[root@node101.yinzhengjie.org.cn ~]# 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’ [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# mkdir -pv /yinzhengjie/data/web/nginx/images/jd mkdir: created directory ‘/yinzhengjie/data/web/nginx/images/jd’ [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# 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>.啟動nginx
[root@node101.yinzhengjie.org.cn ~]# ss -ntl
State Recv-Q Send-Q Local Address:Port Peer Address:Port
LISTEN 0 128 *:22 *:*
LISTEN 0 128 :::22 :::*
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ss -ntl

[root@node101.yinzhengjie.org.cn ~]#
5>.瀏覽器訪問"https://node101.yinzhengjie.org.cn/"首頁
6>.瀏覽器訪問一個不存在的路徑,例如"https://node101.yinzhengjie.org.cn/login/",結果直接向用戶拋出404
二.訪問指定域名的web服務器路徑不存在時跳轉到首頁
1>.編輯子配置文件
[root@node101.yinzhengjie.org.cn ~]# 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;
}
}
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# 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
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]#
2>.重新加載配置文件
[root@node101.yinzhengjie.org.cn ~]# 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 24398 24396 0 15:17 ? 00:00:00 nginx: worker process
nginx 24399 24396 0 15:17 ? 00:00:00 nginx: worker process
nginx 24400 24396 0 15:17 ? 00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# nginx -s reload
[root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# ps -ef | grep nginx | grep -v grep
root 24396 1 0 15:17 ? 00:00:00 nginx: master process nginx
nginx 24510 24396 2 15:23 ? 00:00:00 nginx: worker process

nginx 24513 24396 2 15:23 ? 00:00:00 nginx: worker process
[root@node101.yinzhengjie.org.cn ~]#
3>.瀏覽器訪問一個不存在的路徑,例如"https://node101.yinzhengjie.org.cn/login/"
