Within this article we will show you how to configure Apache to serve your content over a SSL based connection using a self signed certificate.
First of all we generate a self signed certificate using openssl. This will create 2 files, a public certificate and a private key.
mkdir -p /opt/ssl/crt/
openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout yourdomain.key -out yourdomain.crt
Next we configure Apache. As you can see the standard Virtual Hosts are used. However under the Virtual Host for 443 the ‘SSLEngine’ is enabled and the certificate and key files are defined.
Note : If you are using a certifcate that has been signed by a 3rd party Intermediate CA then the location of intermediate certificate can be configued using the ‘SSLCertificatechinFile’ directive.
CustomLog logs/mydomain-access.log common
CustomLog logs/mydomain-ssl-access.log common
Install Apache Module
Next we install the Apache SSL module using Yum.
yum install mod_ssl
To ensure all the changes are applied Apache is then restarted.
Finally we issue a curl to test that our new configuration is working as expected.
For further details in terms of the HTTPS connection and the certificate details an additional -v can be applied to the curl command (i.e curl -ILkv …)
[root@server ~]# curl -ILk https://mydomain.com
