如何配置Nginx使本地(localhost)LNMP网站环境支持多个域名？

说明：请确保LNMP环境已经搭建成功，且能正常支持网站的创建和浏览

其他说明：

文章用 Debian 11作为演示系统

Nginx在Debian系统中的默认安装地址：/etc/nginx

Debian系统默认的网站部署根目录：/var/www/html

文章测试用的两个预设测试域名：

wpscale.cn
wpscale.com

-----------------------------------------------------正文------------------------------------------------------------

1. 在系统中注册两个新的假域名

a.打开hosts文件，

sudo nano /etc/hosts

b.在hosts文件的最后添加下面两行，保存关闭

127.0.0.1        wpscale.cn
127.0.0.1        wpscale.com

2. 在Nginx安装目录中的conf.d目录下中新建两个新的配置文件：sitea.conf和siteb.conf

sitea.conf的内容：

server{
        listen 81;
        listen [::]:81;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm index.nginx-debian.html;

        server_name wpscale.cn;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

         # pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
                           include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
                fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        }
}

siteb.conf的内容：

server{
        listen 82;
        listen [::]:82;

        root /var/www/html;

        # Add index.php to the list if you are using PHP
        index index.php index.html index.htm index.nginx-debian.html;

        server_name wpscale.com;

        location / {
                # First attempt to serve request as file, then
                # as directory, then fall back to displaying a 404.
                try_files $uri $uri/ =404;
        }

         # pass PHP scripts to FastCGI server
        #
        location ~ \.php$ {
                           include snippets/fastcgi-php.conf;
        #
        #       # With php-fpm (or other unix sockets):
                fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        #       # With php-cgi (or other tcp sockets):
        #       fastcgi_pass 127.0.0.1:9000;
        }
}

3. 在部署网站的根目录中新建一个多域名测试目录：WPScale.cn

sudo mkdir /var/www/html/WPScale.cn

4. 在新目录WPScale.cn目录下新建两个方式测试网站内容的目录：wpscale.cn和wpscale.com

并在其中创建一个index.php测试文件

a. 新建wpscale.cn目录

sudo mkdir /var/www/html/WPScale.cn/wpscale.cn

 在wpscale.cn目录下创建index.php测试文件

sudo nano /var/www/html/WPScale.cn/wpscale.cn/index.php

index.php文件的内容为：

<?php echo "Congrats, you are in the wpscale.cn!"; ?>

 b. 新建wpscale.com目录

sudo mkdir /var/www/html/WPScale.cn/wpscale.com

 在wpscale.com目录下创建index.php测试文件

sudo nano /var/www/html/WPScale.cn/wpscale.com/index.php

index.php文件的内容为：

<?php echo "Congrats, you are in the wpscale.com!"; ?>

5. 重启Nginx服务

sudo systemctl restart nginx

6. 测试效果

在浏览器地址栏输入：wpscale.cn/WPScale.cn/wpscale.cn/index.php来测试域名wpscale.cn

在浏览器地址栏输入：wpscale.com/WPScale.cn/wpscale.com/index.php来测试域名wpscale.com
