發布時間：2023/12/20 编程问答 18 豆豆

生活随笔收集整理的這篇文章主要介紹了 openstack集群搭建小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

關閉防火墻及修改vim /etc/selinux/config

[root@localhost ~]# setenforce 0

[root@localhost ~]# getenforce

關閉防火墻

[root@localhost ~]# systemctl stop firewalld

[root@localhost ~]# systemctl disable firewalld

配置時間服務器

controller主機配置

[root@controller ~]# yum install -y chrony

修改配置文件

[root@controller ~]# vim /etc/chrony.conf

重啟服務

[root@controller ~]# systemctl restart chronyd

配置 /etc/hosts

[root@controller ~]# vim /etc/hosts

添加

192.168.100.10 controller

192.168.100.20 compute

[root@compute ~]# ping controller

安裝train版的依賴 [root@controller ~]# yum install -y python-openstackclient openstack-selinux

配置controller數據庫文件

[root@controller ~]# vim /etc/my.cnf

底部添加以下

開啟服務，設置開機自啟動 [root@controller ~]# systemctl enable mariadb.service && systemctl start mariadb.service

安裝rabbitmq消息隊列

[root@controller ~]# yum install rabbitmq-server -y

設置開機自啟

Systemctl enable rabbitmq-server.serivce ; systemctl start rabbitmq-server.service

創建用戶基于權限

[root@controller ~]# rabbitmqctl add_user openstack openstack123

[root@controller ~]# rabbitmqctl set_permissions openstack "." "." ".*"

查看用戶[root@controller ~]# rabbitmqctl list_users

安裝memcached

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

修改文件

[root@controller ~]# vim /etc/sysconfig/Memcached

啟動服務

[root@controller ~]# systemctl enable memcached.service && systemctl start memcached.service

Controller節點登入數據庫

添加keystone庫；

MariaDB [(none)]> create database keystone;????? //創建keystone庫

MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY ' keystone-PASS';

安裝keystone服務

[root@controller ~]# yum install openstack-keystone httpd mod_wsgi -y

修改openstack-keystone文件配置

Vim /etc/keytone/keytone.cof

[token] provider = fernet

同步數據庫

[root@controller ~]# su -s /bin/sh -c "keystone-manage db_sync" keystone

創建令牌

[root@controller ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone

[root@controller ~]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone

設置admin密碼 --bootstrap-password 為：admin

[root@controller ~]# keystone-manage bootstrap --bootstrap-password admin --bootstrap-admin-url http://controller:5000/v3/ --bootstrap-internal-url http://controller:5000/v3/ --bootstrap-public-url http://controller:5000/v3/ --bootstrap-region-id RegionOne

查看數據庫是否成功同步

配置httpd服務器

[root@controller ~]# vim /etc/httpd/conf/httpd.conf

添加controllerIP地址

啟動服務

[root@controller ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/

[root@controller ~]# systemctl enable httpd.service && systemctl start httpd.service

編輯一個腳本admin.sh

往腳本添加內容

Source admin.sh

創建用戶和項目

[root@controller ~]# openstack domain create --description "An Example Domain" example

[root@controller ~]# openstack project create --domain default --description "Service Project" service

[root@controller ~]# openstack project create --domain default --description "Demo Project" myproject

設置myuser密碼為：myuser

[root@controller ~]# openstack user create --domain default --password-prompt myuser User Password: myuser Repeat User Password: myuser

[root@controller ~]# openstack role create myrole

[root@controller ~]# openstack role add --project myproject --user myuser myrole

取消臨時OS_AUTH和OS_PASSWORD環境變量

[root@controller ~]# unset OS_AUTH OS_PASSWORD

輸入admin密碼，密碼為：admin

[root@controller ~]# openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name admin --os-username admin token issue

Password: admin

輸入myuser密碼，密碼為：myuser

[root@controller ~]# openstack --os-auth-url http://controller:5000/v3 --os-project-domain-name Default --os-user-domain-name Default --os-project-name myproject --os-username myuser token issue

Password:? myuser

創建一個myuser.sh腳本

Source admin.sh

Openstack token issue

Source myuser.sh

Openstack token issue

Glance組件

登入mysql數據庫創建glance庫；

MariaDB [(none)]> create database glance;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'glance_PASS';

openstack user create --domain default --password-prompt

password：glance

[root@controller ~]# openstack role add --project service --user glance admin

將glance用戶添加到admin

[root@controller ~]# openstack service create --name glance --description "OpenStack Image" image

[root@controller ~]# openstack endpoint create --region RegionOne image public http://controller:9292

[root@controller ~]# openstack endpoint create --region RegionOne image internal http://controller:9292

[root@controller ~]# openstack endpoint create --region RegionOne image admin http://controller:9292

創建以上網段

安裝glance組件

Yum install -y openstack-glance

配置glance文件

同步數據庫

[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance

啟動自啟服務

[root@controller ~]# systemctl enable openstack-glance-api.service && systemctl start openstack-glance-api.service

上傳鏡像

[root@controller ~]#? glance image-create --name "cirros4" --file cirros-0.4.0-x86_64-disk.img --disk-format qcow2 --container-format bare?? --visibility public

Placement組件

打開數據庫添加placement庫

MariaDB [(none)]> CREATE DATABASE nova_cell0;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'nova_PASS';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'nova_PASS';

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'nova_PASS';

啟動計算服務（包括其依賴項），并將其配置為在系統啟動時自動啟動：

[root@controller ~]#? systemctl enable libvirtd.service openstack-nova-compute.service && systemctl start libvirtd.service openstack-nova-compute.service

確認數據庫中存在計算主機：

[root@compute ~]# openstack compute service list --service nova-compute
