How to add second-level subdomain names in batches with Nginx

Copy code The code is as follows:

if ( $host ~* (.*)\.(.*)\.(.*)) {
set $subdomain $1;
}
location / {
root html/$subdomain;
index index.html index.php;
}

The "~*" above means that it is not case sensitive, and then it is Matching any "xxx.xxx.xxx" type of URL, in the end it is a tragedy, not only matching "www.yourdomian.com" but even URLs such as "What the fuck.$!@.com" are also matched.

Well, that’s right! This is a regular question. It is recommended to read "" and "nginx location command basics" first, and then read on...

Perfect solution

Copy code The code is as follows:

if ( $host ~* (\b(?!www\b)\w )\.\w \.\w ) {
set $subdomain /$1;
}
location / {
root /home/wangyan/public_html$subdomain;
index index.html index.php;
}

The effect can be seen in the picture below. It has been implemented and does not match "www" but it can Matches subdomains containing "www".

To use, please copy the above code to the server {} tag, and then restart nginx.
