Configure HTTPS in Identity Service

The following part describes steps to enable both HTTP and HTTPS with a self-signed certificate.

  1. Generate an RSA private key.

stack@oauth2-0-server:/$ openssl genrsa -out keystone.key 2048
Generating RSA private key, 2048 bit long modulus (2 primes)
e is 65537 (0x010001)
  1. Create a certificate signing request.

stack@oauth2-0-server:/$ openssl req -new -key keystone.key -out keystone.csr
You are about to be asked to enter information that will be incorporated
into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.
Country Name (2 letter code) [AU]:
State or Province Name (full name) [Some-State]:
Locality Name (eg, city) []:
Organization Name (eg, company) [Internet Widgits Pty Ltd]:
Organizational Unit Name (eg, section) []:
Common Name (e.g. server FQDN or YOUR name) []
Email Address []:

Please enter the following 'extra' attributes
to be sent with your certificate request
A challenge password []:
An optional company name []:
  1. Generate a self-signed certificate.

stack@oauth2-0-server:/$ openssl x509 -req -days 365 -in keystone.csr \
-signkey keystone.key -out
Signature ok
subject=C = , ST = , L = , O = , OU = , CN =, emailAddress =
Getting Private key
  1. Append the configuration file for setting the HTTPS port service under the directory /etc/apache2/sites-enabled/.

stack@oauth2-0-server:/$ sudo ln -s \
/etc/apache2/sites-available/000-default.conf \
  1. Modify the apache configuration file and add proxy rules to implement HTTPS support for the Keystone service.

stack@oauth2-0-server:/$ vi 000-default.conf
<VirtualHost *:443>
DocumentRoot /var/www/html
SSLCertificateFile /etc/ssl/certs/
SSLCertificateKeyFile /etc/ssl/certs/keystone.key
SSLEngine on
SSLProtocol  all -SSLv2 -SSLv3
SSLHonorCipherOrder on
ProxyPass "/identity" "unix:/var/run/uwsgi/keystone-wsgi-public.socket|uwsgi://uwsgi-uds-keystone-wsgi-public" retry=0
  1. Restart apache service so that the modified configuration information takes effect.

stack@oauth2-0-server:/$ systemctl restart apache2.service
