How to install wildcards on CentOS Linux 7.4


I am a user of China. Now it’s 2.21 in the morning. I want to ask you how to use your wildcards. Thank you. I use Google translate. My email is, thank you.

My domain

I ran this command:

It produced this output:

My web server is (include version):Nginx 1.12

The operating system my web server runs on is (include version):CentOS Linux 7.4.1708 (Core)

My hosting provider, if applicable, is: yes is tencent.

I can login to a root shell on my machine (yes or no, or I don’t know): yes

I’m using a control panel to manage my site (no, or provide the name and version of the control panel): I’m using the server management system






Thank you. How can I join the test system?


The clients that are listed as supporting ACMEv2 at

(including the latest release, 0.22, of Certbot which was announced yesterday) can get wildcard certificates from the staging (testing) ACMEv2 server

Remember that the certificates issued by the test server are not accepted by web browsers. They will produce an error message whenever someone visits your site. However, you can get experience with the way wildcard certificates from Let’s Encrypt will work.

#5 is using DNSPod DNS servers., dehydrated and GetSSL all support DNS automation with DNSPod.
