Ranger

Ranger is an OpenStack Resource Management tool capable of managing different types of clouds into one platform. Here are the following of what it provides:

  • Multi-region common resource management.
  • Light weight, stateless and interface with external self-service portals.
  • Runs on DCP.
  • Resource agents will run on LCP to orchestrate and keep resources in sync from a

    centralized repository.

Before Setting Up

Make sure ranger-agent is running before installing and running ranger since that is required for connecting with Openstack.

Devstack Installation

  1. Add the following line in local.conf to include ranger repository in your devstack.

    enable_plugin ranger https://git.openstack.org/openstack/ranger

  2. Make sure MYSQL_PASSWORD is included for creating and accessing the database.
  3. Run ./stack.sh from devstack directory.

Installation

1. Navigate to ranger/tools directory:

$ cd /opt/stack/ranger/tools

2. To make changes to the port numbers and other configurations, please go to base_config.py under

the orm folder before continuing to the next steps.

  1. Run ./ranger_create_db.sh to create ranger databases.
  2. Run ./setup_apache.sh to create conf files for each of the services to apache.
  3. Run stack_orm.sh to set up ranger.
  4. If stack_orm.sh is not running properly, navigate to /opt/stack/ranger and run the following:
    1. sudo pip install -r requirements.txt
    2. sudo python setup.py develop 2>&1 | tee $root_dir/tools/install.log

Generate ranger.conf file
