Nginx sets www access without www to change to www

Nginx sets www access without www to change to www

A recently developed Web project is deployed in an LNMP environment. In the past, nginx had only a point theory and was not actually used. The requirements for domain name resolution are as follows:

The user turned to access the http://www.cneotscn.com by entering the http://cneotscn.com and http://www.cneotscn.com. After querying nginx related documents and materials, we finally solved the problem.

The configuration file vhost/www. centoscn. conf (depending on your domain name configuration file) is edited as follows:

.....

......

Server
{

........

Server_namewww.cnotscn.com; // only one

......

}

Add the following code block at the bottom of the file (independent from the code above ):

Server {
Server_namecneotscn.com;
Rewrite ^ (. *) $ http://www.cneotscn.com $1 permanent;
}
