ESXi valid SSL

To have a valid SSL certificate on ESXi webUI (not VCSA) you need to replace rui files in /etc/vmware/ssl/.

  • Log in to the ESXi Shell as a user with administrator privileges.
  • In the directory /etc/vmware/ssl, rename the existing certificates using the following commands. mv rui.crt orig.rui.crt mv rui.key orig.rui.key
  • Copy the new certificate and key to /etc/vmware/ssl.
  • Rename the new certificate and key to rui.crt and rui.key.

My Famipow wildcard certificate is used like this:

cp STAR_famipow_com.crt rui.crt
cp STAR_famipow_com_key.txt rui.key

scp rui* root@${VMHOST}:/etc/vmware/ssl/.
