# Script to deploy certificates to remote server by SSH |
|||
# Note that SSH must be able to login to remote host without a password... |
|||
# SSH Keys must have been exchanged with the remote host. Validate and |
|||
# test that you can login to USER@SERVER from the host running acme.sh before |
|||
# using this script. |
|||
# |
|||
# The following variables exported from environment will be used. |
|||
# If not set then values previously saved in domain.conf file are used. |
|||
# |
|||
# Only a username is required. All others are optional. |
|||
# |
|||
# The following examples are for QNAP NAS running QTS 4.2 |
|||
# export DEPLOY_SSH_CMD="" # defaults to ssh |
|||
# export DEPLOY_SSH_USER="admin" # required |
|||
# export DEPLOY_SSH_SERVER="qnap" # defaults to domain name |
|||
# export DEPLOY_SSH_KEYFILE="/etc/stunnel/stunnel.pem" |
|||
# export DEPLOY_SSH_CERTFILE="/etc/stunnel/stunnel.pem" |
|||
# export DEPLOY_SSH_CAFILE="/etc/stunnel/uca.pem" |
|||
# export DEPLOY_SSH_FULLCHAIN="" |
|||
# export DEPLOY_SSH_REMOTE_CMD="/etc/init.d/stunnel.sh restart" |

# export DEPLOY_SSH_BACKUP="" # yes or no, default to yes |
