# Script for acme.sh to deploy certificates to lighttpd |
||||
|
# |
||||
|
# The following variables can be exported: |
||||
|
# |
||||
|
# export DEPLOY_LIGHTTPD_PEM_NAME="${domain}.pem" |
||||
|
# |
||||
|
# Defines the name of the PEM file. |
||||
|
# Defaults to "<domain>.pem" |
||||
|
# |
||||
|
# export DEPLOY_LIGHTTPD_PEM_PATH="/etc/lighttpd" |
||||
|
# |
||||
|
# Defines location of PEM file for Lighttpd. |
||||
|
# Defaults to /etc/lighttpd |
||||
|
# |
||||
|
# export DEPLOY_LIGHTTPD_RELOAD="systemctl reload lighttpd" |
||||
|
# |
||||
|
# OPTIONAL: Reload command used post deploy |
||||
|
# This defaults to be a no-op (ie "true"). |
||||
|
# It is strongly recommended to set this something that makes sense |
||||
|
# for your distro. |
||||
|
# |
||||
|
# export DEPLOY_LIGHTTPD_ISSUER="yes" |
||||
|
# |
||||
|
# OPTIONAL: Places CA file as "${DEPLOY_LIGHTTPD_PEM}.issuer" |
||||
|
# Note: Required for OCSP stapling to work |
||||
|
# |
||||
|
# export DEPLOY_LIGHTTPD_BUNDLE="no" |
||||
|
# |
||||
|
# OPTIONAL: Deploy this certificate as part of a multi-cert bundle |
||||
|
# This adds a suffix to the certificate based on the certificate type |
||||
|
# eg RSA certificates will have .rsa as a suffix to the file name |
||||
|
# Lighttpd will load all certificates and provide one or the other |
||||
|
# depending on client capabilities |
||||
|
# Note: This functionality requires Lighttpd was compiled against |
||||
|
# a version of OpenSSL that supports this. |
