请教各位一个问题，求解答：nginx多个二级域名使用统一证书?求大佬指点！

Question

前提
我有一个包含泛域名(*.example.com和example.com)的证书;
我的目的nginx,所有example.com一级、二级域名都用这一个证书;
实现方式
方式一：验证通过,但冗余代码太多
每个匹配的域名都加载证书,个人感觉太累赘了,因为证书都是同一个
#example.com
server{
listen443;
server_nameexample.com;
sslon;
ssl_certificate/etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key/etc/letsencrypt/live/example.com/privkey.pem;
location/{
...
}
}
#aaa.example.com
server{
listen443;
server_nameaaa.example.com;
sslon;
ssl_certificate/etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key/etc/letsencrypt/live/example.com/privkey.pem;
location/{
...
}
}
#bbb.example.com
server{
listen443;
server_namebbb.example.com;
sslon;
ssl_certificate/etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key/etc/letsencrypt/live/example.com/privkey.pem;
location/{
...
}
}
方式二：有问题!!!
我想要把方式一中所有证书走统一路径,如何实现?
#所有符合server_name都加载些证书
server{
listen443;
server_name*.example.comexample.com;
sslon;
ssl_certificate/etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key/etc/letsencrypt/live/example.com/privkey.pem;
}
#example.com
server{
listen443;
server_nameexample.com;
location/{
...
}
}
#aaa.example.com
server{
listen443;
server_nameaaa.example.com;
location/{
...
}
}
#bbb.example.com
server{
listen443;
server_namebbb.example.com;
location/{
...
}
}
问题
如何不累赘(所有证书走统一路径)实现证书加载?
