Hi,
I just wanted to share this in case it helps someone else. I’m pulling over quite a lot of domains from another server. I need to setup a self-signed SSL (until the site goes live, and we can then setup LetsEncrypt). What I was doing, is creating the self-signed cert from the GUI. However, this was a bit boring 
So I wrote a little script that will do it quicker:
create-self-signed-for-domain.sh
#!/bin/bash
domain=$1
email='[email protected]'
user_domain_is_in=""
locations_found=$(find /home/ -type d -name "$domain" -exec ls -ld {} \; | awk '{print $3}')
for location in $locations_found; do
if [ "$location" != "root" ]; then
user_domain_is_in="$location"
break
fi
done
# check if the user is valid!
if [ "$user_domain_is_in" == "" ]; then
echo "ERROR: User not found!"
exit 1
fi
echo "USER GRABBED: $user_domain_is_in"
cert=$(v-generate-ssl-cert "$domain" "$email" "US" "California" "San Francisco" "MyCompany LLC" "www.$domain")
path=($cert)
tmp_path="${path[-1]#Directory: }"
echo "TMP PATH: '$tmp_path'"
v-add-web-domain-ssl "$user_domain_is_in" "$domain" "$tmp_path"
Simply invoke with:
bash create-self-signed-for-domain.sh the_domain.com
This will save me a lot of time - so I thought I’d share it, in case it helps someone else 
I’m not sure if its worth porting with the official repo, or not?
Change the value of $email to whatever you want
Cheers
Andy
