SSL - ESXi

Installing manual certs on an ESXi server

PIKEDOM.COM has some very good instructions.

Something to know if you got your certs from certbot:

• The file you're replacing rui.crt with is either cert.pem or fullchain.pem (depending on whether you've set up with one or more than one domain in your certs.
• The file you're replacing rui.key with is privkey.pem.
• Both of the files from certbot may have a number attached to the end of the filename itself.

So...

SSH into the server...

• cd /etc/vmware/ssl
• mv rui.crt orig.rui.crt
• mv rui.key orig.rui.key
• vi rui.crt
  • Paste in the content of fullchain.pem
• vi rui.key
  • Paste in the content of privkey.pem
• reboot

Using SCP to install the certs

You should be able directly install certs on your ESXi server thanks to vmWares bad habit of allowing SSH as root...

THIS HAS NOT YET BEEN FULLY TESTED!

You have been warned.

• scp /etc/letsencrypt/live/NAME.DOMAIN.TLD/fullchain.pem root@NAME.DOMAIN.TLD:/etc/vmware/ssl/rui.crt
• scp /etc/letsencrypt/live/NAME.DOMAIN.TLD/privkey.pem root@NAME.DOMAIN.TLD:/etc/vmware/ssl/rui.key
• ssh root@NAME.DOMAIN.TLD reboot

Of course, you'll replace NAME.DOMAIN.TLD with the actual name of your server...
