This module was written to have your Odoo installation request SSL certificates from https://letsencrypt.org automatically.
After installation, this module generates a private key for your account at
letsencrypt.org automatically in $data_dir/letsencrypt/account.key. If you
want or need to use your own account key, replace the file.
For certificate requests to work, your site needs to be accessible via plain HTTP, see below for configuration examples in case you force your clients to the SSL version.
After installation, trigger the cronjob Update letsencrypt certificates and watch your log for messages.
This addon depends on the openssl binary and the acme_tiny and IPy
python modules.
For installing the OpenSSL binary you can use your distro package manager. For Debian and Ubuntu, that would be:
sudo apt-get install openssl
For installing the ACME-Tiny python module, use the PIP package manager:
sudo pip install acme-tiny
For installing the IPy python module, use the PIP package manager:
sudo pip install IPy
This addons requests a certificate for the domain named in the configuration
parameter web.base.url - if this comes back as localhost or the like,
the module doesn't request anything.
If you want your certificate to contain multiple alternative names, just add
them as configuration parameters letsencrypt.altname.N with N starting
from 0. The amount of domains that can be added are subject to rate
limiting.
Note that all those domains must be publicly reachable on port 80 via HTTP, and
they must have an entry for .well-known/acme-challenge pointing to your odoo
instance.
The module sets up a cronjob that requests and renews certificates automatically.
After the first run, you'll find a file called domain.crt in
$datadir/letsencrypt, configure your SSL proxy to use this file as certificate.

This module uses openssl to generate CSRs suitable to be submitted to
letsencrypt.org. In order to do this, it copies /etc/ssl/openssl.cnf to a
temporary and adapts it according to its needs (currently, that's just adding a
[SAN] section if necessary). If you want the module to use another configuration
template, set config parameter letsencrypt.openssl.cnf.
After refreshing the certificate, the module attempts to run the content of
letsencrypt.reload_command, which is by default sudo service nginx reload.
Change this to match your server's configuration.
You'll also need a matching sudo configuration, like:
your_odoo_user ALL = NOPASSWD: /usr/sbin/service nginx reload
Further, if you force users to https, you'll need something like for nginx:
if ($scheme = "http") {
set $redirect_https 1;
}
if ($request_uri ~ ^/.well-known/acme-challenge/) {
set $redirect_https 0;
}
if ($redirect_https) {
rewrite ^ https://$server_name$request_uri? permanent;
}
and this for apache:
RewriteEngine On
RewriteCond %{HTTPS} !=on
RewriteCond %{REQUEST_URI} "!^/.well-known/"
RewriteRule ^/?(.*) https://%{SERVER_NAME}/$1 [R,L]
In case you need to redirect other nginx sites to your Odoo instance, declare an upstream for your odoo instance and do something like:
location /.well-known {
proxy_pass http://yourodooupstream;
}
If you're using a multi-database installation (with or without dbfilter option)
where /web/databse/selector returns a list of more than one database, then
you need to add letsencrypt addon to wide load addons list
(by default, only web addon), setting --load option.
For example, --load=web,letsencrypt
