[Openstack - Train] Centos에 설치하기(1) - Repository 설정

기본적인 OS 및 네트워크 환경이 설정 되어 있다는 가정하에 바로 Openstack을 설치 하는 과정을 정리하였습니다. 

Openstack이전의 설정 과정은 docs.openstack.org를 참고하길 바랍니다. 

 

 

1-1. Openstackrepository 설정 

- 이 단계는 모든 openstack node에서 설정을 해야 한다. 

[root@controller ~]# yum install centos-release-openstack-train

Complete!

 

Repository설정이 완료 된 후에는 현재 시스템의 PKG를 최신화로 업그레이드를 한다. 

[root@controller ~]# yum -y upgrade

 

업그이드가 완료 되면 Openstack client를 설치 한다. 

[root@controller ~]# yum install python-openstackclient -y

Openstack-selinux PKG를 설치한다. 

: REDHAT이나 Centos 계정에서는 기본적으로  Selinux가 활성화 되는데  openstack-selinux  pkg를 설치함으로써 Openstack내 서비스들에 대한 보안 정책을 자동으로 관리한다. 

[root@controller ~]# yum install -y openstack-selinux
