nginx server_name configuration actual nginx nginx reverse proxy what is nginx

1) The server_name directive is mainly used to configure name-based virtual hosts ( in http > server inside ), the matching order of the server_name instructions after receiving the request are:

1.Accurate server_name matching, for example:

server {

listen 80;

server_namessdr.info www.ssdr.info;

...

}

2.String starting with * wildcard:

server {

listen 80;

server_name* . ssdr.info;

...

}

3.A string ending with *wildcard:

server {

listen 80;

server_name www . $;

...

}

nginx will match servername

in the order of

1,2,3,4

, and the search will stop after only one match

.

2) Configure multiple second-level domain names for a site in a server block : In the actual website directory structure, we usually separate the second-level domain names of the site Create a directory. We can also use regular capture to configure multiple second-level domain names in a

server

block:

server { Listen 80; server_name ~^(.+) ? Domain.com $; Index index.html;

if ($ host = domain.com) { reWrite ^ http://www.domain.com permanent; } root /data/wwwsite/domain.com/

$1

/;

}

The directory structure of the site should be as follows:

/data/wwwsite/ domain.com/www/

/data/wwwsite/domain.com/nginx/

When accessing

www.domain.com

like this, the

root

directory is

/data/wwwsite/domain. com/www/

,

nginx.domain.com

is

/data/wwwsite/domain.com/nginx/, and so on. The function of the if statement after is to redirect the direction of domain.com to www.domain.com, which not only solves the problem of home directory access to the website, but also increases The domain name weight of seo

to

www.domain.com. 3) Multiple regular expressions: If you use regular expressions in server_name, and the following location field uses regular expressions, this will not work. For references like

$1

, $2

, the solution is to assign it to a named variable through the

set command: server{ listen 80; server _name ~ ^(.+)?.howtocn.org$; set $www_root $1; root /data/wwwsite/ssdr.info/$www_root/; location ~ .*.php?$ { fastcgi_pass 127.0 .0.1:9000; fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME/data/wwwsite/ssdr.info/$fastcgi_script_name;

include fastcgi_params;

}

}

The above introduces the server_name configuration of nginx, including server and nginx aspects. I hope it will be helpful to friends who are interested in PHP tutorials.
