Multi-domain reverse proxy configuration instance
Configure a reverse proxy for multiple domain names on one VPS. for example, we have two domain names: test1.idcfree.com and test2.idcfree.com. we want the user to access test1.idcfree.com to view the content of www.linuxidc.com, if you want to see www.baidu.org.tw when you access test2.idcfree.com, you only know the existence of test1.idcfree.com and test2.idcfree.com, but do not know the existence of www.linuxidc.com and www.baidu.org.tw.

First, you need to direct the domain names test1.idcfree.com and test2.idcfree.com to the vps ip address.

Then add two files in the/etc/nginx/sites-available directory named test1.idcfree.com and test2.idcfree.com.

The content of the test1.idcfree.com file is as follows:
Server {
Listen 80;
Server_name test1.idcfree.com;

Location /{
Proxy_pass http://www.linuxidc.com /;
Proxy_redirect off;
Proxy_set_header X-Real-IP $ remote_addr;
Proxy_set_header X-Forwarded-For $ proxy_add_x_forwarded_for;
}
}

The content of the file test2.idcfree.com is as follows:
Server {
Listen 80;
Server_name test2.idcfree.com;

Location /{
Proxy_pass http://www.baidu.org.tw /;
Proxy_redirect off;
Proxy_set_header X-Real-IP $ remote_addr;
Proxy_set_header X-Forwarded-For $ proxy_add_x_forwarded_for;
}
}
Then run the following command:


Cd/etc/nginx/sites-enabled
Ln-sf/etc/nginx/sites-available/test1.idcfree.com. ln-sf/etc/nginx/sites-available/test2.idcfree.com.
/Etc/init. d/nginx restart

When you access test1.idcfree.com in your browser, the content of www.linuxidc.com will appear. when you access test2.idcfree.com, the content of www.baidu.org.tw will appear.
