OpenStack--T版-Glance组件部署流程
创建数据库实例和数据库用户
[root@ct ~]# mysql -u root -p
MariaDB [(none)]> CREATE DATABASE glance;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit
创建用户、修改配置文件
- 创建OpenStack的Glance用户
#创建用户前,需要首先执行管理员环境变量脚本(此处已经在~/.bashrc 中定义过了)
[root@ct ~]# openstack user create --domain default --password GLANCE_PASS glance #创建glance用户
[root@ct ~]# openstack role add --project service --user glance admin
#将glance用户添加到service项目中,并且针对这个项目拥有admin权限;注册glance的API,需要对service项目有admin权限
[root@ct ~]# openstack service create --name glance --description "OpenStack Image" image
#创建一个service服务,service名称为glance,类型为image;创建完成后可以通过 openstack service list 查看
- 创建镜像服务 API 端点,OpenStack使用三种API端点代表三种服务:admin、internal、public
[root@ct ~]# openstack endpoint create --region RegionOne image public http://ct:9292
[root@ct ~]# openstack endpoint create --region RegionOne image internal http://ct:9292
[root@ct ~]# openstack endpoint create --region RegionOne image admin http://ct:9292
- 安装 openstack-glance 软件包
[root@ct ~]# yum -y install openstack-glance
- 修改glance配置文件
glance有两个配置文件:
/etc/glance/glance-api.conf
/etc/glance/glance-registry.conf
[root@ct ~]# cp -a /etc/glance/glance-api.conf{,.bak}
[root@ct ~]# grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf
- 添加glance-api.conf配置
#传入修改的参数
[root@ct ~]# openstack-config --set /etc/glance/glance-api.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@ct/glance
[root@ct ~]# openstack-config --set /etc/glance/glance-api.conf keystone_authtoken www_authenticate_uri http://ct:5000

- 修改glance-registry.conf 配置文件
#备份、过滤注释信息
[root@ct ~]# cp -a /etc/glance/glance-registry.conf{,.bak}
[root@ct ~]# grep -Ev '^$|#' /etc/glance/glance-registry.conf.bak > /etc/glance/glance-registry.conf

- 初始化glance数据库,生成相关表结构;(不管有多少个controler,只需要初始化一次即可)
[root@ct ~]# su -s /bin/sh -c "glance-manage db_sync" glance
- 开启glance服务(此处开启之后会生成存放镜像的目录/var/lib/glance/image)
[root@ct ~]# systemctl enable
[root@ct ~]# systemctl start openstack-glance-api.service
- 查看端口(也可以使用lsof -i:9292 )
[root@ct ~]# netstat -natp | grep 9292
- 赋予openstack-glance-api.service服务对存储设备的可写权限(-h:值对符号连接/软链接的文件修改)
[root@ct ~]# chown -hR glance:glance /var/lib/glance/
- 镜像导入
[root@ct ~]# yum -y install lrzsz
[root@ct ~]# rz -E
rz waiting to receive.
- 先上传cirros镜像到控制节点的/root,然后导入glance,最后查看是否创建成功
[root@ct ~]# openstack image create --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros
- 查看镜像的两种方式
[root@ct ~]# openstack image list
[root@ct ~]# glance image-list
##小结
因为OpenStack上创建虚拟机需要镜像支持,所以先行进行部署
- 部署思路:
1、创建数据库、授权
2、创建openstack用户、授权、管理
3、修改配置文件(glance-api.conf、glance-registry.conf)
