Nginx Letsencrypt Issues while changing a site's domain name with HTTPS and Letsencrypt SSL Certificate

Hi @eva2000 ,
Good day!

I am trying to follow your instructions on the forum post below on how to change a site's domain name with HTTPS and Letsencrypt SSL Certificate to other domains, but I got some issues that need your help to give some advise with:

https://community.centminmod.com/th...-https-and-letsencrypt-ssl-certificate.18381/

Notes:

• My website is just newly installed a fresh WordPress via centmin.sh menu option 22
• Let's say I was used old domain = olddomain.com and new domain = newdomain.com
• Both olddomain.com and newdomain.com are using Cloudflare's DNS Records/ Configuration
• Server name = "thundersv"

** Step 1: I had done copying my Letsencrypt issued SSL certificate files from old domain name directory to create a copy in new domain name's directory by following command:

Code (Text):

cp -a /usr/local/nginx/conf/ssl/olddomain.com /usr/local/nginx/conf/ssl/newdomain.com

❯❯ At this Step I noticed that there is no changes made yet for all the copied files under the following newly created folder for the new domain:

** Step 2: I had done copying my old domain's Nginx vhost config file at:

---

and created my new domain's Nginx vhost config file at

by following command:

Code (Text):

cp -a /usr/local/nginx/conf/conf.d/olddomain.com.ssl.conf /usr/local/nginx/conf/conf.d/newdomain.com.ssl.conf

❯❯ At this Step I noticed that there is Only One new Nginx vhost config file created, which was "newdomain.com.ssl.conf" for the new replacement domain, but it seems there was a missing of a basic domain file: "newdomain.com.conf" when a new vHost is added.

** Step 3: I tried to modify my newly created Nginx vhost config file:

I also tried to modify all references to olddomain.com in:

by following command:

Code (Text):

sed -i 's|olddomain.com|newdomain.com|g' /usr/local/nginx/conf/conf.d/newdomain.com.ssl.conf
sed -i 's|olddomain.com|newdomain.com|g' /usr/local/nginx/conf/ssl/newdomain.com/newdomain.com.crt.key.conf

Then noticed that in the "Step 1" above, when copying all files under the old domain: /usr/local/nginx/conf/ssl/olddomain.com to newly created folder for the new domain: /usr/local/nginx/conf/ssl/newdomain.com. The above "sed -i" command in your instructions didn't mention anything about modifying/ replacing the remaining copied files under the new domain folder, which are:

So I just leave those files there and done nothing.

** Step 4: Since this is just a testing, i already set up my server to have more than enough disk space for domain's site directory and public web root files, in order to make a copy so that both /home/nginx/domains/olddomain.com and /home/nginx/domains/newdomain.com exist at same time.

Then, I tried follow your instructions to use the following command to proceed with domain's site directory and public web root files copying:

Code (Text):

cp -a /home/nginx/domains/olddomain.com /home/nginx/domains/newdomain.com

After that, I tried to restart Nginx, and got the following errors:

Code (Text):

[10:33][root@thundersv home]# nprestart
Redirecting to /bin/systemctl restart nginx.service
Job for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xeu nginx.service" for details.

Then, I tried to open "systemctl status nginx.service", I saw this:
