1、配置index.html網頁

[[email protected]-10-1-1-161 conf.d]# cat /web/sing/index.html 
<h1>www.test1.com</h1>
[[email protected]-10-1-1-161 conf.d]# cat /root/html/index.html 
<h1>www.test2.com</h1>




2、配置conf.d目錄下配置檔案

[[email protected]-10-1-1-161
 
 conf.d]# pwd
/etc/nginx/conf.d
[[email protected]-10-1-1-161 conf.d]# ls
test1.conf  test2.conf  test3.conf
[[email protected]-10-1-1-161 conf.d]# cat test1.conf 
server {
listen 8083;
server_name 127.0.0.1:8083;
location / {
root /web/sing/;
index index.html index.htm;
}
}


[[email protected]-10-1-1
 
-161 conf.d]# cat test2.conf 
server {
listen 8086;
server_name 127.0.0.1:8086;
location / {
root /root/html/;
index index.html index.htm;
}
}


[[email protected]-10-1-1-161 conf.d]# cat test3.conf 
upstream abc.com {
        server 127.0.0.1:8083 fail_timeout=20s;
        server 127.0.0.1:8086 fail_timeout=20s;

        #ip_hash; 開啟後就會訪問到一臺上
       
}

server {

        listen       
 
80;
        server_name  oa.test.com;
        location / {
             #反向代理的地址
             proxy_pass http://abc.com;     
        }
}





3、配置hosts

[[email protected]-10-1-1-161 conf.d]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
123.58.251.166 oa.test.com 


[[email protected]-10-1-1-161 conf.d]# nginx -s reload



4、開始訪問

[[email protected]-10-1-1-161 ~]# curl http://oa.test.com
<h1>www.test1.com</h1>
[[email protected]-10-1-1-161 ~]# curl http://oa.test.com
