3. Configure multi-domain and multi-site

Tell me how to configure multiple domain names and multiple sites on one server.
There are several ways to implement multisite:

Multiple Domains, Multiple Sites
multi-port, multi-site

For example, a.com b.comboth point to the server 1.2.3.4. What we need to realize is that different websites appear when accessing these two domain names. They both serve on port 80. That is to say, there is no need to access like a.com:8080 b.com:8081this, but a.coma website appears directly when accessing , b.comanother website appears when you visit it.

The default website file of nginx is in /var/www/htmlthe folder. Generally, there is no special requirement and no need to modify it. Just put the file in this directory and use it.

1. Create a site configuration file

Add a file in /etc/nginx/sites-availablethe foldera.com

cd /etc/nginx/sites-available
vi a.com

Add the following:

server {
    
    
    listen       80;    # 监听 80 端口，但只有用 a.com 访问的时候才会匹配到这个配置
    server_name  a.com; # 这里是 a.com 的域名

    root   /var/www/html/a.com; # 这里是 a.com 的根目录
    index  index.html index.htm;
}

same b.comreason

At this point, sites-availablethere are already two files in

a.com
b.com

2. Enable Site Profiles

There is a knowledge point that needs to be explained. When you check it nginx.conf , you can see such a sentence, as shown below.
It means to include site-enabled/all the configurations below

Above we have sites-availablecreated two websites in the directory. Now we need to sites-enabledcreate a link file of these two configuration files in the folder, the meaning of the link file is similar to the shortcut in the Windows desktop, it is a link. But when using it, it is the same as using the source file.

cd /etc/nginx/sites-enabled
ln -s ../sites-available/a.com a.com
ln -s ../sites-available/b.com b.com

This sites-enabledcreates two linked files in the folder. This is equivalent to having two files sites-enabledin the directory that are exactly the same as the directorysites-available

like this

3. Restart nginx to make it take effect

systemctl restart nginx

Four, finished

In this way, when accessing, it is to access the contents of the directory a.comon the server. When accessing, it is to access the contents of the directory on the server/var/www/html/a.com/
b.com/var/www/html/b.com/
