Web Hosting is the use of special hardware and software technology to a host computer into multiple "virtual" host, each virtual host has a separate domain name and IP address (or shared IP address), a complete Internet server Features. On the same hardware, same operating system on servers running different programs that are open for multiple users, without disturbing each other; and each user have their own part of the system resources (IP address, file storage space, memory, CPU time, etc. ).
The use of virtual hosts, without providing a separate site for each Nginx server you want to run or run a set Nginx process alone. Web Hosting provides the ability to run on the same server, Nginx process the same set of multiple sites.
Under nginx, a server is a virtual host label. Configuring virtual host in three ways:
- Based virtual hosting, a domain name to distinguish between virtual hosts - Application: External Website
- Port-based virtual hosting, through the port to distinguish between virtual hosts - Application: the company's internal Web site, external website management background
- Ip-based virtual hosting, the basic need
First, based on domain name
Under hosts need to modify the file, plus the corresponding relationship between IP and domain names, or else access is not visible.
vim /etc/hosts 192.168.22.33 www.test.com 192.168.22.33 www.cookie.com
nginx.conf file in the editor nginx
{Server # virtual host
the listen 80; # listening port
server_name www.test.com; # monitor domain
Localtion / {
the root HTML -ling; # root positioning
index index.html;
}
}
Server {
the listen 80 ;
server_name WWW. cookie.com;
LOCATION / {
the root HTML - Wang;
index index.html;
}
}
Then access the appropriate domain name www.test.com or www.cookie.com will be a corresponding index interface.
Second, based on the port
Third, based on IP
To each server to configure an IP, Different direct access to IP will visit virtual host.
