Openstack Install Guide(Victoria - CentOS)

• CentOS 8.2 환경 기준 설치

 

1. OS 환경

1.1 CentOS 8.2

1.2 All-in-One 기준 구성

1.3 기본적으로 네트워크 외부 통신 연결 가능상태

1.4 네트워크 포토 최소 2~4개 필요

2. Openstack OS 기본 설정

• 모든 서버에 같은 설정
• 네트워크 서비스 기본 설정 완료 상태

 

2.1 기본 툴 설치

$ yum install vim net-tools -y          ### 기본 툴 $ yum install nfs-utils -y                 ### NAS 스토리지 연결시 필요

 

2.2 네트워크 설정

• IPv6 중지 및 설정 확인

$ vim /etc/sysctl.conf  net.ipv6.conf.all.disable_ipv6 = 1  net.ipv6.conf.default.disable_ipv6 = 1  net.ipv6.conf.lo.disable_ipv6 = 1 $ sysctl -p

• 방화벽 중지

$ systemctl stop firewalld $ systemctl disable firewalld

2.3 SSH KEY 설정

• 모든 서버 동시 수행

$ ssh-keygen -t rsa $ ssh-copy-id root@{모든 서버}

 

2.4 SELINUX 비활성화

$ vim /etc/selinux/config   SELINUX=disabled $ reboot

 

2.5 Openvswitch 설치 및 패키지 설치

3. Openstack 설치 구성

3.1 Openstack 설치 패키지 구성

 

### kolla-ansible 구성 설치 ### Openstack Victoria 버전  $ pip3 install kolla-ansible==11.0.0    ### ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall. ### 에러 발생시 대처 $ pip3 install --ignore-installed PyYAML $ mkdir -p /etc/kolla $ cp -r /usr/local/share/kolla-ansible/etc_examples/kolla/* /etc/kolla $ cp -r /usr/local/share/kolla-ansible/ansible/inventory/ /root/ $ vim /etc/ansible/ansible.cfg  [defaults]  host_key_checking=False  pipelining=True  forks=100

3.2 All-in-One 노드 설정

$ cd /root/inventory  ### localhost -> {hostname} 으로 변경 $ sed -i s/localhost/호스트네임/g all-in-one $ vim /root/inventory/all-in-one [control] all01       ansible_connection=local [network] all01       ansible_connection=local [compute] all01       ansible_connection=local [storage] all01       ansible_connection=local [monitoring] all01       ansible_connection=local [deployment] all01       ansible_connection=local

 

3.3 Kolla globals.yml 파일 설정

3.4 Kolla Password 설정

$ kolla-genpwd ### Openstack 서비스들의 암호를 설정하는것 $ vim /etc/kolla/passwords.yml Database_password: openstack ### MariaDB 접속 암호 설정 Keystone_admin_password: openstack ### Horizon 접속 암호 설정 ### 하단 Octavia 설치시 암호 설정 Octavia_ca_password: openstack Octavia_database_password: openstack Octavia_keystone_password: openstack ### 추가 서비스들에 대하여 변경하여 사용 필요.

3.5 Cinder Volume 구성

$ pvcreate /dev/sdb1 ### cinder-volumes 명칭으로 구성해야한다. 명칭 변경시 하단 변경 필요 $ vgcreate cinder-volumes /dev/sdb1

3.6 Openstack 설치

$ cd ~/inventory  ### All-in-One인 경우 $ kolla-ansible -i all-in-one bootstrap-servers  $ kolla-ansible -i all-in-one prechecks -vvv  $ kolla-ansible -i all-in-one deploy -vvv ###  MultiNode인 경우 $ kolla-ansible -i multinode bootstrap-servers $ kolla-ansible -i multinode prechekcs -vvv $ kolla-ansible -i multinode deploy -vvv

$ mount /dev/sdb /var/lib/docker/volumes/nova_compute/_data/instances ### 내부 디스크 사용시 instances 권한 42436으로 변경 필요 $ chown 42436:42436 /var/lib/docker/volumes/nova_compute/_data/instances

 

• Openstack CLI 설치
