이 장에서는 Controller 와 compute node에만 설치를 한다.
Controller Node에 NOVA PKG를 설치시 Compute node에 대한 PKG도 같이 설치 할 경우 controller node도 compute node 처럼 사용할 수 있다.
하지만 여기서는 각각 분리하여 설치 한다.
A) Controller Node에 설치
A-1) DB생성
## DB 생성 전 확인
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "show databases;"
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |
| keystone |
| mysql |
| performance_schema |
| placement |
+--------------------+
## DB 생성
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "CREATE DATABASE nova_api;"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "CREATE DATABASE nova;"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "CREATE DATABASE nova_cell0;"
## DB 생성 후 확인
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "show databases;"
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |
| keystone |
| mysql |
| nova |
| nova_api |
| nova_cell0 |
| performance_schema |
| placement |
+--------------------+A-2) DB 권한 설정
## 권한 설정 전 확인
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} mysql -e "select Host,User,PASSWORD from user where User='nova_api';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} mysql -e "select Host,User,PASSWORD from user where User='nova';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} mysql -e "select Host,User,PASSWORD from user where User='nova_cell0';"
##DB 권한 설정
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'nova.123';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova.123';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'nova.123';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova.123';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'nova.123';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova.123';"
## 권한 설정 반영
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} -e "Flush Privileges;"
## 권한 설정 확인
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} mysql -e "select Host,User,PASSWORD from user where User='nova';"
+-----------+------+-------------------------------------------+
| Host | User | PASSWORD |
+-----------+------+-------------------------------------------+
| localhost | nova | *1C82B157DB331DFF216C43C8731768139C895506 |
| % | nova | *1C82B157DB331DFF216C43C8731768139C895506 |
+-----------+------+-------------------------------------------+
## nova DB 계정만 사용함으로 아래 계정은 필요 없으며, 출력도 되지 않는다. -- 참고 사항!!!!!
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} mysql -e "select Host,User,PASSWORD from user where User='nova_cell0';"
[root@controller ~]# mysql -u${DB_USER} -p${DB_PASSWD} mysql -e "select Host,User,PASSWORD from user where User='nova_api';"A-3) Service User 생성 및 role 권한 설정
## Service User 생성

B) Compute Node에 설치
Compute node로 사용할 모든 서버에 설치를 진행한다.
B-1) PKG 설치
[root@compute01 ~]# yum install openstack-nova-compute -yB-2) config 백업
## 파일명 변경
[root@compute01 ~]# mv /etc/nova/nova.conf /etc/nova/nova.conf.orig
## 이전 파일의 퍼미션 확인
[root@compute01 ~]# ls -al /etc/nova/nova.conf.orig
-rw-r----- 1 root nova 218078 10월 16 23:10 /etc/nova/nova.conf.orig
## 주석을 제외한 config 만 출력하여 config 파일로 생성
[root@compute01 ~]# cat /etc/nova/nova.conf.orig | grep -Ev "^#|^$" | sed -e "s/\[/\n\[/g" > /etc/nova/nova.conf
## 이전과 동일한 퍼미션 설정
[root@compute01 ~]# chown root.nova /etc/nova/nova.conf
[root@compute01 ~]# chmod 640 /etc/nova/nova.confB-3) config 수정
[root@compute01 ~]# cat /etc/nova/nova.conf
