Install and setup SSL for ODOO, with centos operating system, its free SSL and Secure too. Make your odoo life with security. Take our yearly support to get all security protection for your ERP support.

Update the system

As usual make sure the system is fully up to date before installing any packages:
# yum -y update

Install Apache

We are going to use Apache as our web server, install it using this command:
# yum -y install httpd

Install mod_ssl

Install mod_ssl as well as we are going to need it to configure our Let’s Encrypt SSL certificate:
# yum -y install mod_ssl

Configure Apache

Create a document root folder for your site:
# mkdir /var/www/test


Create a virtual host config file for your site by opening it with nano and then pasting the following contents inside:
# nano /etc/httpd/conf.d/test-site.conf
<VirtualHost *:80>
DocumentRoot “/var/www/test”
ErrorLog “/var/log/httpd/test.error_log”
CustomLog “/var/log/httpd/test.access_log” common
Add a index.html file for testing purposes later with the following contents:

# nano /var/www/test/index.html
It works!

Change owner of the “/var/www/test” directory to the apache user so Apache can read the directory:
# chown -R apache:apache /var/www/test
Remember to change “test” for your site’s name.
Now that we have Apache installed we can continue by installing certbot.

Install certbot

To install certbot first we need to make sure we have the EPEL repository enabled, to do that execute the following command:
# yum -y install epel-release
Make sure yum-utils is installed:

# yum -y install yum-utils
Then install certbot for Apache:

# yum -y install certbot-apache
Now that we have certbot installed, run certbot with the following command:

# certbot-apache
Certbot will ask you for the names you would like to activate HTTPS for:

Saving debug log to /var/log/letsencrypt/letsencrypt.log
Plugins selected: Authenticator apache, Installer apache
Starting new HTTPS connection (1):

Which names would you like to activate HTTPS for?
Select the appropriate numbers separated by commas and/or spaces, or leave input
blank to select all options shown (Enter ‘c’ to cancel):
Press enter to continue and then optionally if you want you can redirect your sites to HTTPS:

Please choose whether or not to redirect HTTP traffic to HTTPS, removing HTTP access.
1: No redirect – Make no further changes to the webserver configuration.
2: Redirect – Make all requests redirect to secure HTTPS access. Choose this for
new sites, or if you’re confident your site works on HTTPS. You can undo this
change by editing your web server’s configuration.
Select the appropriate number [1-2] then [enter] (press ‘c’ to cancel):
If everything goes well you should see the following output:

Congratulations! You have successfully enabled and

You should test your configuration at:

Configure automatic renewal

Now we are going to add a cronjob so our Let’s Encrypt SSL certificates can be renewed automatically.

First run the following command so we can have nano as the default editor:

# export EDITOR=/bin/nano
Then execute the following command to edit the crontab:

# crontab -e
Let’s Encrypt recommends the automatic renew cronjob to run twice a day, to do that add the following line and then save and exit the crontab:

* */12 * * * /usr/bin/certbot renew >/dev/null 2>&1
Now you should have successfully installed and configured Let’s Encrypt with Apache.


Some command might helpful and be guided to what you doing… For expert technical people. 😉
