pip install pip --upgrade
pip install django-sshkm
deactivate

Configure httpd

Create config file /etc/httpd/conf.d/sshkm.conf with the following content:

Alias /sshkm/static/ /usr/lib/sshkm/lib/python2.7/site-packages/sshkm/static/

<Directory /usr/lib/sshkm/lib/python2.7/site-packages/sshkm/static/>
  Require all granted
</Directory>

WSGIScriptAlias /sshkm /usr/lib/sshkm/lib/python2.7/site-packages/sshkm/wsgi.py/
WSGIDaemonProcess sshkm user=sshkm group=sshkm python-path=/usr/lib/sshkm/lib/python2.7/site-packages home=/usr/lib/sshkm processes=4
WSGIProcessGroup sshkm

<Directory /usr/lib/sshkm/lib/python2.7/site-packages>
  <Files wsgi.py>
    Require all granted
  </Files>
</Directory>

Configure SSHKM

/etc/sshkm/sshkm.conf

ALLOWED_HOSTS = ['*']

STATIC_URL = '/sshkm/static/'
LOGIN_URL = '/sshkm/login/'

CELERY_BROKER_URL = 'amqp://'
CELERY_RESULT_BACKEND = 'rpc'

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'sshkm',
        'USER': 'sshkm',
        'PASSWORD': 'sshkm',
    }
}

Configure your Firewall

# allow to connect to HTTP
firewall-cmd --zone=public --add-service=http
firewall-cmd --permanent --zone=public --add-service=http

Configure SELinux

# you don't need this two commands if you don't use SQLite
semanage fcontext -a -t httpd_sys_rw_content_t "/usr/lib/sshkm/lib/python2.7/site-packages/sshkm/db.sqlite3"

Enable and start services

systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service

systemctl enable celery.service
systemctl start celery.service

systemctl enable mariadb.service
systemctl start mariadb.service

systemctl enable httpd.service
systemctl restart httpd.service

Create Database

mysql
create database sshkm;
create user 'sshkm'@'localhost' identified by 'sshkm';
grant all on sshkm.* to 'sshkm'@'localhost';
exit

Start working

Connect to http://youhost/sshkm and login as user admin (default password: admin).
In the settings menu you can change the password and upload the master private and public key which is used later to connect to your servers to deploy all other public keys.
Now you can define hosts, groups, keys, os-users and the permissions which are combining everything.
In the hosts-menu you can deploy your configurations to the host/s.
