Simplest shell script for LetsEncrypt free Certificate client
Pure written in bash, no dependencies to python , acme-tiny or LetsEncrypt official client. Just one script, to issue, renew your certificates automatically.
Probably it's the smallest&easiest&smartest shell script to automatically issue&renew the free certificates from LetsEncrypt.
Do NOT require to be root/sudoer
.

#How to use
-
Clone this project: https://github.com/Neilpang/le.git
-
Install le:
./le.sh install
You don't have to be root then, altough it is recommended.
Which does 3 jobs:
- create and copy
le.sh
to your home dir:~/.le
All the certs will be placed in this folder. - create symbol link:
/usr/local/bin/le -> ~/.le/le.sh
. (You must be root to do so.) - create everyday cron job to check and renew the cert if needed.
Ok, you are ready to issue cert now. Show help message:
root@v1:~# le.sh

root@v1:~/le# le issue
Usage: le issue webroot|no|apache|dns a.com [www.a.com,b.com,c.com]|no [key-length]|no
Set the param value to "no" means you want to ignore it.
For example, if you give "no" to "key-length", it will use default length 2048.
And if you give 'no' to 'cert-file-path', it will not copy the issued cert to the "cert-file-path".
In all the cases, the issued cert will be placed in "~/.le/domain.com/"
Just issue a cert:
le issue /home/wwwroot/aa.com aa.com www.aa.com,cp.aa.com
First argument /home/wwwroot/aa.com
is the web root folder, You must have write
access to this folder.
Second argument "aa.com" is the main domain you want to issue cert for.
Third argument is the additional domain list you want to use. Comma separated list, which is Optional.
You must point and bind all the domains to the same webroot dir:/home/wwwroot/aa.com
The cert will be placed in ~/.le/aa.com/
The issued cert will be renewed every 80 days automatically.
Install issued cert to apache/nginx etc.
le installcert aa.com /path/to/certfile/in/apache/nginx /path/to/keyfile/in/apache/nginx /path/to/ca/certfile/apahce/nginx "service apache2|nginx reload"
Install the issued cert/key to the production apache or nginx path.
The cert will be renewed every 80 days by default (which is configurable), Once the cert is renewed, the apache/nginx will be automatically reloaded by the command: service apache2 reload
or service nginx reload
Use Standalone server to issue cert( requires you be root/sudoer, or you have permission to listen tcp 80 port):
Same usage as all above, just give no
as the webroot.
The tcp 80
port must be free to listen, otherwise you will be prompted to free the 80
port and try again.
le issue no aa.com www.aa.com,cp.aa.com
Use Apache mode(requires you be root/sudoer, since it is required to interact with apache server):
If you are running a web server, apache or nginx, it is recommended to use the Webroot mode. Particularly, if you are running an apache server, you can use apache mode instead. Which doesn't write any file to your web root folder.
Just set string "apache" to the first argument, it will use apache plugin automatically.
le issue apache aa.com www.aa.com,user.aa.com
All the other arguments are the same with previous.
Use DNS mode:
Support the latest dns-01 challenge.
le issue dns aa.com www.aa.com,user.aa.com
Use domain api to automatically add dns record is not finished yet. So, you must manually add the txt record to finish verifying.
You will get the output like bellow:
Add the following txt record:
Domain:_acme-challenge.aa.com
Txt value:9ihDbjYfTExAYeDs4DBUeuTo18KBzwvTEjUnSwd32-c
Add the following txt record:
Domain:_acme-challenge.www.aa.com
Txt value:9ihDbjxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Please add those txt records to the domains. Waiting for the dns to take effect.
Then just retry with 'renew' command:
le renew aa.com
Ok, it's finished.
