我的域名是https://www.liuquanhao.com，但是我访问https://www.lzj666.com却访问到我的站，而且证书都是我的，但是http://www.lzj666.com却是他自己的站。我这个是什么情况？我问客服，他说是正常显现。。

以下是客服回复：

您好，久等了，联系后端核实，这个不是镜像，是由于您使用的是共享虚拟主机，共享主机都是共有一个 ip 地址的，所以部署了 https 后，其他站点也可以通过 https 访问到，但其他网站访问 https 会出现证书不授信，这个不影响的，如果您介意，建议你最好将共享主机升级到独享主机部署 https，使用独立 ip 就不会出现这个问题了，谢谢

但实际 ip 并不同：

liuxu@liuxu-TM1612:~$ dig +noall +answer www.liuquanhao.com
www.liuquanhao.com.	213	IN	A	139.129.155.148
liuxu@liuxu-TM1612:~$ dig +noall +answer www.lzj666.com
www.lzj666.com.		1	IN	A	139.129.155.150

而且有一堆邻居是一样的情况：

https://www.lzj666.com 17 17
https://139.129.155.147 15 15
https://139.129.155.145 15 15
https://139.129.155.153 15 15
https://139.129.155.151 14 14
https://139.129.155.157 14 14
https://139.129.155.154 14 14

ssl 的原因是因为共用一个/etc/ssl/certs/ca-certificates.crt？可域名访问串呢。。。

据我所知，访问域名时 nginx 的server_name会拒绝其他域名访问的，与listen 443 ssl并无关。。
