Vesta control panel use main sites SSL cert
Here is how to re-use your site SSL for both the site and the Vesta control panel. If you are using Letsencrypt then both the site and the CP will use the auto renewed SSL cert.
* This assumes Nginx front end with an Apache backend and you have already enabled Letsencrypt on your main website.
Backup the old CP SSl files:
mv /usr/local/vesta/ssl/certificate.crt /usr/local/vesta/ssl/oldcpssl.crt
mv /usr/local/vesta/ssl/certificate.key /usr/local/vesta/ssl/oldcpssl.key
Create the Symlinks:
ln -s /home/admin/conf/web/ssl.yoursite.crt /usr/local/vesta/ssl/certificate.crt
ln -s /home/admin/conf/web/ssl.yoursite.key /usr/local/vesta/ssl/certificate.key
service vesta restart
* You may need to clear your browser cache.
You can now access https://yoursite:8083 and get the LE SSL cert rather than a warning.
