#创建glance数据库并授权
mysql -uroot -ploongson -e “CREATE DATABASE glance;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON glance.* TO ‘glance’@‘localhost’ IDENTIFIED BY ‘loongson’;”
mysql -uroot -ploongson -e “GRANT ALL PRIVILEGES ON glance.* TO ‘glance’@’%’ IDENTIFIED BY ‘loongson’;”
#2.创建服务凭据
#（1）在keystone上创建glance用户
#以下命令在local_user表创建glance用户
#注意以下命令需要输入密码
openstack user create --domain default --password-prompt glance
#（2）在keystone上将glance用户添加为service项目的admin角色(权限)
#以下命令无输出
openstack role add --project service --user glance admin
#（3）创建glance镜像服务的实体
#以下命令在service表中增加glance项目
openstack service create --name glance --description “OpenStack Image” image
#3.创建镜像服务的 API 端点（endpoint）
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
#查看API端点
openstack endpoint list
#2安装openstack-glance
yum install -y openstack-glance
#3.配置文件修改
#（1）glance-api.conf
#文件路径：/etc/glance/glance-api.conf
#修改前先备份
cp /etc/glance/glance-api.conf /etc/glance/glance-api.conf.bac

#4同步数据库
#(1)为glance镜像服务初始化同步数据库
#生成的相关表
su -s /bin/sh -c “glance-manage db_sync” glance
#（2）同步完成进行连接测试
#保证所有需要的表已经建立，否则后面可能无法进行下去
mysql -uglance -ploongson -e “use glance;show tables;”
#5.glance镜像服务启动并设置开机自启
systemctl enable openstack-glance-api.service
systemctl start openstack-glance-api.service
systemctl status openstack-glance-api.service
#6.验证glance操作
#下载loongnix镜像
wget ftp://10.2.5.21/os/lnd_loongarch-10/iso/Loongnix-20.mini.loongarch64.rc1.b2.qcow2
#上传镜像(qcow2格式)
glance image-create --name “loongnix” --file Loongnix-20.mini.loongarch64.rc1.b2.qcow2 --disk-format qcow2 --container-format bare --visibility=public
#查看镜像
glance image-list
#上传镜像(iso格式)
#glance image-create --name “loongnix-iso” --file livecd-loongnix-server-20-mini-loongarch64-beta8-202107120440.iso --disk-format iso --container-format bare --visibility=public
