    这是一个创建于 629 天前的主题,其中的信息可能已经有所发展或是发生改变。
    程序是这个 https://oneinstack.com/faq/letsencrypt/ 基于 ACME
    直接添加单一的不带 www 的域名是没有问题的,一加 www 马上根就 NX,加泛域名根也 NX

    What Are You Doing?
    1. Use HTTP Only
    2. Use your own SSL Certificate and Key
    3. Use Let's Encrypt to Create SSL Certificate and Key
    q. Exit
    Please input the correct option: 3

    Please input domain(example: www.example.com): aaa.com
    domain=aaa.com

    Please input the directory for the domain:aaa.com :
    (Default directory: /data/wwwroot/aaa.com):
    Virtual Host Directory=/data/wwwroot/aaa.com

    Create Virtul Host directory......
    set permissions of Virtual Host directory......

    Do you want to add more domain name? [y/n]: y

    Type domainname or IP(example: example.com other.example.com): www.aaa.com
    domain list=www.aaa.com

    Let's Encrypt Verify error! DNS problem: NXDOMAIN looking up A for aaa.com

    一直非常奇怪的一件事,不加 www 这个第二域名的情况下,并不会 NX
    What Are You Doing?
    1. Use HTTP Only
    2. Use your own SSL Certificate and Key
    3. Use Let's Encrypt to Create SSL Certificate and Key
    q. Exit
    Please input the correct option: 3

    Please input domain(example: www.example.com): aaa.com
    domain=aaa.com

    Please input the directory for the domain:aaa.com :
    (Default directory: /data/wwwroot/aaa.com):
    Virtual Host Directory=/data/wwwroot/aaa.com

    Create Virtul Host directory......
    set permissions of Virtual Host directory......

    Do you want to add more domain name? [y/n]: n

    Do you want to redirect all HTTP requests to HTTPS? [y/n]:
