Use RDO to deploy OpenStack graphic tutorials in O01-linux CentOS7

First, preface

1.RDO is an open source project in Red Hat, the full name of RPM distribution of OpenStack, that can help us deploy OpenStack projects quickly.

Official Deployment Documentation: https://www.rdoproject.org/install/packstack/

2. This installation is basically in accordance with the official documentation of the steps to operate, in addition to the second part of the pre-installation environment preparation of the 3rd. This deployment is a single-node experimental environment, the version is the latest stable version of Queens.

Additionally, RDO can also be used to deploy a multi-node environment, as described in the official documentation.

3. Test the Environment:

Tool: VirtualBox

Operating system: CentOS7

Virtual machine configuration: 4-core, 6G memory, 25G capacity of hard disk space. ( official recommended configuration:machine with at least 16GB RAM, processors with hardware virtualization extensions, and at l East one network adapter.)

Virtual Machine ip:192.168.137.20 (is a static IP and can be connected to the extranet, IP deployment Method Link: http://www.cnblogs.com/suhaha/p/8619102.html)

Second, pre-installation environment preparation

1./etc/environment Configuring environment variables in Files

Iv. errors that may be encountered ( When installing OpenStack )

1.error:root:failed to load plugin from file ssl_001.py

Workaround:

For example, it is possible that the Python-setuptools package is not installed. Then use Yum to install, for example, after the installation is complete and then execute the sudo packstack--allinone command to continue installing OpenStack.

2.error:error appeared during Puppet run:192.168.137.20_controller.pp

Error:execution of '/usr/bin/yum-d 0-e 0-y install Openstack-aodh-common ' returned 1: Error downloading packages :

You'll find full trace in Log/var/tmp/packstack/20180321-130307-4ja7pr/manifests/192.168.137.20_controller.pp.log

Workaround: Manually install the error pack

The amount ... Actually said that the current Openstack-aodh-common is the newest ...

That being the case, then execute the sudo packstack--allinone command again (install again without reporting this error ...) ）

3.Error:error appeared during Puppet run:192.168.137.20_controller.pp

Error:/stage[main]/swift::keystone::auth/keystone::resource::service_identity[swift]/keystone_user[swift]: Could not evaluate: Command: ' OpenStack [' User ', ' show ', '--format ', ' shell ', [' Swift ', '--domain ', ' default '] ' have Been running for more than-seconds (tried 2, for a total of seconds)

Workaround:

is the online check see the solution (original address: https://www.redhat.com/archives/rdo-list/2016-July/msg00010.html), said to be required to update the/etc/hosts file, Add the FQDN toit.

FQDN is a fully qualified domain name/whole domain name abbreviation, all called fully qualified domain name, that is, the domain name, Access will be resolved by DNS, get IP. Using the command hostname-f to view the FQDN, I found the Openstack-rdo, which is the same as my hostname, so I add the following in the /etc/hosts file and run it again

(Note: This deployment after processing this error will be able to successfully install, if there are other errors in the actual installation, you can find a solution by themselves online)

At this point, the deployment is complete.
