Setup RDO Openstack with HTTPS
$ mkdir -p /etc/pki/tls/certs
$ mkdir -p /etc/pki/tls/private
$ mkdir -p /root/packstackca/certs
$ openssl req -x509 -sha256 -newkey rsa:2048 -keyout openstack.key -out openstack.crt -days 1024 -nodes
Note: Enter fqdn as hostname
$ cp openstack.crt /etc/pki/tls/certs/
$ cp openstack.key /etc/pki/tls/private/
$ ln -s /etc/pki/tls/certs/ssl_vnc.crt /root/packstackca/certs/$(hostname -I | cut -f1 -d' ')ssl_vnc.crt
$packstack --gen-answer-file=youranwserfile.packstack
CONFIG_PROVISION_DEMO=n
CONFIG_KEYSTONE_ADMIN_PW=<password>
CONFIG_HORIZON_SSL=y
CONFIG_SSL_CERT_DIR=/root/packstackca/
nohup packstack --answer-file=youranwserfile.packstack &
A] Enable https for keystone:
1] Modify keystone httpd conf files:-
Update "/etc/httpd/conf.d/10-keystone_wsgi_admin.conf" file. Add below in <VirtualHost *:35357> tag:-
ServerAlias ServerAlias ServerAlias localhost
SSLEngine on SSLCertificateFile "/etc/pki/tls/certs/openstack.crt" SSLCertificateKeyFile "/etc/pki/tls/private/openstack.key"
Update "/etc/httpd/conf.d/10-keystone_wsgi_main.conf" file. Add below in <VirtualHost *:5000> tag:-
2] Add openstack.crt to ca for python:
$ pip install certifi
find the path of the cacert.pem file
$python
>>> import certifi
>>> certifi.where()
'/usr/lib/python2.7/site-packages/certifi/cacert.pem'
then add your own ca file in to that cacert.pem
$cat /root/openstack.crt >> /usr/lib/python2.7/site-packages/certifi/cacert.pem
3] Create https endpoints for Keystone:
$source keystonerc_admin
$openstack endpoint create --region <Region> --enable keystone admin https://<fqdn>:35357/v3
$openstack endpoint create --region <region> --enable keystone internal https://<fqdn>:5000/v3
$openstack endpoint create --region <region> --enable keystone public https://<fqdn>:5000/v3
4] Delete older keystone endpoints:
#List keystone endpoints
$openstack endpoint list | grep keystone | grep http:
$openstack endpoint delete <endpoint id>
5] Update [ssl] section in "/etc/keystone/keystone.conf":
[ssl]
enable=true
certfile = /etc/pki/tls/certs/openstack.crt
keyfile = /etc/pki/tls/private/openstack.key
6] Restart httpd and keystone service:
$service httpd restart
#Install Openstack-utils
$yum install openstack-utils -y
$openstack-service restart
7] Update OS_AUTH_URL in keystonerc_admin and test keystone:
Replace with OS_AUTH_URL=https://:5000/v3 in keystonerc_admin.
$ source keystonerc_admin
$ openstack endpoint list
8] Update all services conf files to use https endpoints for keystone and uncomment insecure=true.Use fqdn when specifying endpoints.
"/etc/nova/nova.conf"
[keystone_authtoken]
auth_uri=https://<fqdn>:5000/
auth_url=https:/<fqdn>:35357
insecure=true
Note: Update keystone endpoint based on valued in conf files.
auth_uri=http://1.2.3.4:5000/ ⇒ auth_uri=https://<fqdn>:500
Do same for placement api.
B] Enable https for other services: We are using haproxy for this.
1] Install and configure haproxy:
$ yum install haproxy -y
$cat openstack.crt openstack.key > /etc/haproxy/openstack.pem
Download and Replace haproxy.cfg with ⇒ haproxy.cfg
Update <fqdn>, <ip> in haproxy.cfg.
2] Update ports for services:
