# Using deploy api
|
|
|
|
Here are the scripts to deploy the certs/key to the server/services.
|
|
|
|
## 1. Deploy the certs to your cpanel host.
|
|
|
|
(cpanel deploy hook is not finished yet, this is just an example.)
|
|
|
|
Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
|
|
|
|
Then you can deploy now:
|
|
|
|
```sh
|
|
export DEPLOY_CPANEL_USER=myusername
|
|
export DEPLOY_CPANEL_PASSWORD=PASSWORD
|
|
acme.sh --deploy -d example.com --deploy --deploy-hook cpanel
|
|
```
|
|
|
|
## 2. Deploy ssl cert on kong proxy engine based on api.
|
|
|
|
Before you can deploy your cert, you must [issue the cert first](https://github.com/Neilpang/acme.sh/wiki/How-to-issue-a-cert).
|
|
|
|
(TODO)
|
|
|
|
## 3. Deploy the cert to remote server through SSH access.
|
|
|
|
The ssh deploy plugin allows you to deploy certificates to a remote host
|
|
using SSH command to connect to the remote server. The ssh plugin is invoked
|
|
with the following command...
|
|
|
|
```sh
|
|
acme.sh --deploy -d example.com --deploy-hook ssh
|
|
```
|
|
Prior to running this for the first time you must tell the plugin where
|
|
and how to deploy the certificates. This is done by exporting the following
|
|
environment variables. This is not required for subsequent runs as the
|
|
values are stored by acme.sh in the domain configuration files.
|
|
|
|
Required...
|
|
```
|
|
export ACME_DEPLOY_SSH_USER=username
|
|
```
|
|
Optional...
|
|
```
|
|
export ACME_DEPLOY_SSH_CMD=custom ssh command
|
|
export ACME_DEPLOY_SSH_SERVER=url or ip address of remote host
|
|
export ACME_DEPLOY_SSH_KEYFILE=filename for private key
|
|
export ACME_DEPLOY_SSH_CERTFILE=filename for certificate file
|
|
export ACME_DEPLOY_SSH_CAFILE=filename for intermediate CA file
|
|
export ACME_DEPLOY_SSH_FULLCHAIN=filename for fullchain file
|
|
export ACME_DEPLOY_SSH_REMOTE_CMD=command to execute on remote host
|
|
export ACME_DEPLOY_SSH_BACKUP=yes or no
|
|
```
|
|
|
|
**ACME_DEPLOY_SSH_USER**
|
|
Username at the remote host that SSH will login with. 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@URL from the host running acme.sh before using this script.
|
|
|
|
The USER@URL at the remote server must also have has permissions to write to
|
|
the target location of the certificate files and to execute any commands
|
|
(e.g. to stop/start services).
|
|
|
|
**ACME_DEPLOY_SSH_CMD**
|
|
You can customize the ssh command used to connect to the remote host. For example
|
|
if you need to connect to a specific port at the remote server you can set this
|
|
to, for example, "ssh -p 22" or to use `sshpass` to provide password inline
|
|
instead of exchanging ssh keys (this is not recommended, using keys is
|
|
more secure).
|
|
|
|
**ACME_DEPLOY_SSH_SERVER**
|
|
URL or IP Address of the remote server. If not provided then the domain
|
|
name provided on the acme.sh --deploy command line is used.
|
|
|
|
**ACME_DEPLOY_SSH_KEYFILE**
|
|
Target filename for the private key issued by LetsEncrypt.
|
|
|
|
**ACME_DEPLOY_SSH_CERTFILE**
|
|
Target filename for the certificate issued by LetsEncrypt.
|
|
If this is the same as the previous filename (for keyfile) then it is
|
|
appended to the same file.
|
|
|
|
**ACME_DEPLOY_SSH_CAFILE**
|
|
Target filename for the CA intermediate certificate issued by LetsEncrypt.
|
|
If this is the same as a previous filename (for keyfile or certfile) then
|
|
it is appended to the same file.
|
|
|
|
**ACME_DEPLOY_SSH_FULLCHAIN**
|
|
Target filename for the fullchain certificate issued by LetsEncrypt.
|
|
If this is the same as a previous filename (for keyfile, certfile or
|
|
cafile) then it is appended to the same file.
|
|
|
|
**ACME_DEPLOY_SSH_REMOTE_CMD**
|
|
Command to execute on the remote server after copying any certificates. This
|
|
could be any additional command required for example to stop and restart
|
|
the service.
|
|
|
|
**ACME_DEPLOY_SSH_BACKUP**
|
|
Before writing a certificate file to the remote server the existing
|
|
certificate will be copied to a backup directory on the remote server.
|
|
These are placed in a hidden directory in the home directory of the SSH
|
|
user
|
|
```sh
|
|
~/.acme_ssh_deploy/[domain name]-backup-[timestamp]
|
|
```
|
|
Any backups older than 180 days will be deleted when new certificates
|
|
are deployed. This defaults to "yes" set to "no" to disable backup.
|
|
|
|
|
|
###Eamples using SSH deploy
|
|
The following example illustrates deploying certifcates to a QNAP NAS
|
|
(tested with QTS version 4.2.3)
|
|
|
|
```sh
|
|
export ACME_DEPLOY_SSH_USER="admin"
|
|
export ACME_DEPLOY_SSH_KEYFILE="/etc/stunnel/stunnel.pem"
|
|
export ACME_DEPLOY_SSH_CERTFILE="/etc/stunnel/stunnel.pem"
|
|
export ACME_DEPLOY_SSH_CAFILE="/etc/stunnel/uca.pem"
|
|
export ACME_DEPLOY_SSH_REMOTE_CMD="/etc/init.d/stunnel.sh restart"
|
|
|
|
acme.sh --deploy -d qnap.example.com --deploy-hook ssh
|
|
```
|
|
Note how in this example both the private key and certificate point to
|
|
the same file. This will result in the certificate being appended
|
|
to the same file as the private key... a common requirement of several
|
|
services.
|
|
|
|
The next example illustates deploying certificates to a Unifi
|
|
Contolller (tested with version 5.4.11).
|
|
|
|
```sh
|
|
export ACME_DEPLOY_SSH_USER="root"
|
|
export ACME_DEPLOY_SSH_KEYFILE="/var/lib/unifi/unifi.example.com.key"
|
|
export ACME_DEPLOY_SSH_FULLCHAIN="/var/lib/unifi/unifi.example.com.cer"
|
|
export ACME_DEPLOY_SSH_REMOTE_CMD="openssl pkcs12 -export \
|
|
-inkey /var/lib/unifi/unifi.example.com.key \
|
|
-in /var/lib/unifi/unifi.example.com.cer \
|
|
-out /var/lib/unifi/unifi.example.com.p12 \
|
|
-name ubnt -password pass:temppass \
|
|
&& keytool -importkeystore -deststorepass aircontrolenterprise \
|
|
-destkeypass aircontrolenterprise \
|
|
-destkeystore /var/lib/unifi/keystore \
|
|
-srckeystore /var/lib/unifi/unifi.example.com.p12 \
|
|
-srcstoretype PKCS12 -srcstorepass temppass -alias ubnt -noprompt \
|
|
&& service unifi restart"
|
|
|
|
acme.sh --deploy -d unifi.example.com --deploy-hook ssh
|
|
```
|
|
In this exmple we execute several commands on the remote host
|
|
after the certificate files have been copied... to generate a pkcs12 file
|
|
compatible with Unifi, to import it into the Unifi keystore and then finaly
|
|
to restart the service.
|
|
|
|
Note also that once the certificate is imported
|
|
into the keystore the individual certificate files are no longer
|
|
required. We could if we desired delete those files immediately. If we
|
|
do that then we should disable backup at the remote host (as there are
|
|
no files to backup -- they were erased during deployment). For example...
|
|
```sh
|
|
export ACME_DEPLOY_SSH_BACKUP=no
|
|
# modify the end of the remote command...
|
|
&& rm /var/lib/unifi/unifi.example.com.key \
|
|
/var/lib/unifi/unifi.example.com.cer \
|
|
/var/lib/unifi/unifi.example.com.p12 \
|
|
&& service unifi restart
|
|
```
