Wordpress 第二个子域重定向到主域，但URL与第二个域保持相同

很奇怪，看到这个问题的标题描述。详情如下:

1） 创建了一个带有“a1”的a记录。表示子域为：

a1.example.com

2） 由

“sudo mkdir-p/var/www/a1.example.com/html/”创建的目录

3） 通过“sudo nano/etc/nginx/sites available/a1.example.com”创建服务器块

4） 在服务器块内部，核心部分：

server {
listen 80;
listen [::]:80;

root /var/www/a1.example.com/html;
index index.html index.htm;

server_name a1.example.com

location / {
try_files $uri $uri/ =404;
}
}

5） 创建链接：
sudo ln-s/etc/nginx/sites available/a1.example.com/etc/nginx/sites enabled/

6） 
sudo nano/etc/nginx/nginx.conf
，取消注释：
server\u names\u hash\u bucket\u size 64

确保：
include/etc/nginx/sites enabled/*有吗

7） 重新启动的nginx:
sudo服务nginx重新启动

棘手的部分：通过这样做，第一个子域
a1.example.com
工作正常。
但是当我尝试创建第二个子域时，
b2.example.com
按照上面的确切步骤，
b2.example.com
根本不起作用：它将重定向到主页，但URL保持为
b2.example.com

有什么不对劲

多谢各位


a1.example.com的配置

我注意到“304”和“301”，http状态。但仍然没有线索

您是否检查了nginx的错误和访问日志？提示：*sudo nano…/…“没有创建目录。可能是输入错误。我想你的意思是*mkdir…/…”。谢谢semm0，是的，它是一个输入错误，应该是“sudo mkdir-p”，我现在就修改它。不管怎样，目录创建了alreadyOkay:）那么错误和访问日志呢？目录和其中文件的权限/所有者是否正确？权限/所有权，我所做的是：sudo chown-R www-data:www-data/var/www/b2.example.com/html/var/www/a1.example.com/htmlHi semm0，我用访问日志信息更新了。仍在努力找出问题所在
