OpenStack Train版-3.安装glance镜像服务

安装glance镜像服务

创建数据库并授权

mysql -u root 
create database glance;
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_DBPASS';
GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_DBPASS';
flush privileges;

创建glance用户

source ~/admin-openrc
openstack user create --domain default --password GLANCE_PASS glance

将管理员admin用户添加到glance用户和项目中

openstack role add --project service --user glance admin

创建glance服务实体

openstack service create --name glance --description "OpenStack Image" image

创建glance服务API端点,OpenStack使用三种API端点变种代表每种服务：admin、internal、public

openstack endpoint create --region RegionOne image public http://controller:9292
openstack endpoint create --region RegionOne image internal http://controller:9292
openstack endpoint create --region RegionOne image admin http://controller:9292

安装glance软件包

yum install openstack-glance -y

编辑glance配置文件 /etc/glance/glance-api.conf

cp -a /etc/glance/glance-api.conf{,.bak}
grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf

openstack-config --set /etc/glance/glance-api.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@controller/glance

openstack-config --set /etc/glance/glance-api.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_type password
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken project_name service
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken username glance
openstack-config --set /etc/glance/glance-api.conf keystone_authtoken password GLANCE_PASS
openstack-config --set /etc/glance/glance-api.conf paste_deploy flavor keystone

openstack-config --set /etc/glance/glance-api.conf glance_store stores file,http
openstack-config --set /etc/glance/glance-api.conf glance_store default_store file
openstack-config --set /etc/glance/glance-api.conf glance_store filesystem_store_datadir /var/lib/glance/images/

编辑镜像服务的另一个组件文件 /etc/glance/glance-registry.conf

cp -a /etc/glance/glance-registry.conf{,.bak}
grep -Ev '^$|#' /etc/glance/glance-registry.conf.bak > /etc/glance/glance-registry.conf

openstack-config --set /etc/glance/glance-registry.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@controller/glance

openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken www_authenticate_uri http://controller:5000
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_url http://controller:5000
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken auth_type password
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_domain_name Default
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken user_domain_name Default
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken project_name service
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken username glance
openstack-config --set /etc/glance/glance-registry.conf keystone_authtoken password GLANCE_PASS
openstack-config --set /etc/glance/glance-registry.conf paste_deploy flavor keystone

同步写入镜像数据库

su -s /bin/sh -c "glance-manage db_sync" glance

启动glance服务并设置开机自启

systemctl enable openstack-glance-api.service openstack-glance-registry.service
systemctl restart openstack-glance-api.service openstack-glance-registry.service
lsof -i:9292

赋予openstack-glance-api.service服务对存储设备的可写权限

chown -hR glance:glance /var/lib/glance/

下载cirros镜像验证glance服务

wget -c http://download.cirros-cloud.net/0.5.1/cirros-0.5.1-x86_64-disk.img

上传镜像

#这里不要使用官方文档里面的glance image-create这样的写法，新版本的OpenStack已经不支持，尽量统一使用以openstack开头的命令写法
openstack image create --file ~/cirros-0.5.1-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros

查看镜像

openstack image list
glance image-list

#查看镜像的物理文件
ll /var/lib/glance/images/

##删除镜像的命令
openstack image delete <ID>
