mysql -uroot -p000000 -e "grant all privileges on glance.* to glance@'%' identified by '000000';"
mysql -uroot -p000000 -e "grant all privileges on glance.* to glance@localhost identified by '000000';"

修改Glance配置文件 ​

备份 ​

cp /etc/glance/glance-api.conf /etc/glance/glance-api.bak

去掉配置文件的所有注释和空行，生成新的配置文件 ​

编辑配置文件就行编辑 ​

vi /etc/glance/glance-api.conf

修改[database]部分 ​

[database]
connection = mysql+pymysql://glance:000000@controller/glance

修改[keystong_authtoken],修改[paste_deploy] ​

[keystong_authtoken]
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
username = glance
password = 000000
project_name = project
user_domain_name = Default
project_domain_name = Default
[paste_deploy]
flavor = keystone

修改[glance_store] ​

[glance_store]
stores = file
default_store = file
filesystem_store_datadir = /var/lib/glance/images/

初始化Glance数据库 ​

同步数据库 ​

mysql -uroot -p000000
use glance;
show tables;

Glance组件初始化 ​

创建Glance用户并分配角色 ​

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

创建Glance服务及服务端点 ​

创建一个名字为Glance，类型为image的服务 ​

openstack service create --name glance image

创建镜像服务端点 ​

openstack endpoint create --region RegionOne glance public http://controller:9292

创建内部组件的服务端点 ​

openstack endpoint create --region RegionOne glance internal http://controller:9292

创建admin用户访问的端点 ​

openstack endpoint create --region RegionOne glance admin http://controller:9292

启动服务并设置开机自启 ​

systemctl enable openstack-glance-api.service && systemctl start openstack-glance-api.service

验证Glance服务 ​

查看端口占用情况 ​

netstat -tnlup | grep 9292

查看服务运行状态 ​

systemctl status openstack-glance-api.service
