}

domain name resolution address is the server’s IP, access to nginx will determine which site to request, and then match to the corresponding project

# the second method

# go to nginx configuration folder

cd /usr/local/nginx/conf

# new folder vhost

Create www.test.com.conf

under the folder vhost

server {
    listen       80;
    server_name  www.test.com;

    location/{
        root   html/www.test.com;
        index  index.html index.htm;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   html;
    }

}

pay attention to change root path (www.test.com come in to visit the project path)
here new www.test.com can be named according to your domain name, according to the above template, Change server_name and root.
. Create a new project name for each project

cd /usr/local/nginx/conf

vim nginx.conf

http {
    ......

    #引入其它配置
    include       vhost/*.conf;
