Configure CentOS 7 based Ansible provisioning server for OpenStack

-

To configure a CentOS 7 system as ansible provisioning server for OpenStack environment we need the following packages to be installed:


    • gcc
    • python-devel
    • python-pip
    • pbr
    • python-openstackclient
    • shade

But these packages need to be installed in a sequence, else you may get some dependency related errors.

Steps to install the above packages:


1. Install epel repo and gcc package on CentOS 7 system:

   # yum install gcc epel-release -y

2. Install ansible using yum:

   # yum install ansible -y

3. Install python-devel and python-pip

   # yum install python-devel python-pip -y 

4. Now use pip to upgrade python-pip package:

   # pip install --trusted-host pypi.python.org --upgrade pip
   Collecting pip
   Downloading pip-9.0.1-py2.py3-none-any.whl (1.3MB)
    100% |████████████████████████████████| 1.3MB 203kB/s
   Installing collected packages: pip
   Found existing installation: pip 8.1.2
    Uninstalling pip-8.1.2:
      Successfully uninstalled pip-8.1.2
   Successfully installed pip-9.0.1  

5. Install the pbr package:

   # pip install  --trusted-host pypi.python.org pbr
   Collecting pbr
   Downloading pbr-3.0.1-py2.py3-none-any.whl (99kB)
    100% |████████████████████████████████| 102kB 232kB/s
   Installing collected packages: pbr
   Successfully installed pbr-3.0.1

6. Install the python-openstackclient:

   # pip install  --trusted-host pypi.python.org python-openstackclient   

7. Finally install the shade package:

   # pip install  --trusted-host pypi.python.org  shade
Now ansible server is ready to communicate with your OpenStack infrastructure over OpenStack apis.
