there are several ways to apply a cert for a site
1. go to website page , click "add SSL" as screenshot , then place your cert and key there
2. you can also issue a self-signed cert first via panel , and then override its cert to the wild card.
e.g. by default all the cert are saved in
so you can also directly editing all those files to apply new cert.
3. but , if you have a lot of sites , manually edit them every 3 months is very annoying , so you can use soft link way.
save your wildcard cert in one location, for example
now , remove these files
and then use ln -s command to link them
ln -s /etc/letsnecrypt/wildcard.crt /etc/letsencrypt/live/domain.com/fullchain.pem
ln -s /etc/letsencrypt/wildcard.key /etc/letsencrypt/live/domain.com/privkey.pem
so this way , the linked file will update when you update the source file , so you don't need to change them again.
4. you can also directly modify the vhost conf file to your wildcard cert/key
as screenshot, for enterprise
change the red-marked text to , as example above , to
would also work.
please do remember restart OpenLiteSpeed or LiteSpeed enterprise after you apply the change.
