Controller节点配置

创建数据库和授权用户

创建数据库

[root@controller ~]# mysql -uroot -p000000
MariaDB [(none)]> CREATE DATABASE glance; 
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '000000'; 
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '000000'; 
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> exit

创建用户服务和API的endpoint

创建用户服务

[root@controller ~]# openstack user create --domain default --password 000000 glance
#创建glance用户
[root@controller ~]# 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；
[root@controller ~]# 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API的endpoint

三种API端点代表三种服务：admin、internal、public

[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

安装 openstack-glance 软件包

[root@controller ~]# yum -y install openstack-glance

修改Glance配置文件

修改glance–api.conf

[root@controller ~]# cp -a /etc/glance/glance-api.conf{,.bak}
#在保留源文件属性的前提下进行批量复制
[root@controller ~]# grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf
# 对glance-api.conf.bak反向过滤掉空格和注释项，覆盖到glance-api.conf
[root@controller ~]# vi /etc/glance/glance-api.conf
[DEFAULT]

connection = mysql+pymysql://glance:000000@controller/glance

stores = file,http                   #存储类型，file：文件，http：基于api调用的方式，把镜像放到其他存储上
default_store = file                 #默认存储方式
filesystem_store_datadir = /var/lib/glance/images/     #指定镜像存放的本地目录

www_authenticate_uri = http://controller:5000          #指定认证的keystone的URI
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = Default
user_domain_name = Default
project_name = service                  #glance用户针对service项目拥有admin权限
username = glance
password = 000000

修改glance-registry.conf

[root@controller ~]# cp -a /etc/glance/glance-registry.conf{,.bak}
[root@controller ~]# grep -Ev '^$|#' /etc/glance/glance-registry.conf.bak > /etc/glance/glance-registry.conf
[root@controller ~]# vi /etc/glance/glance-registry.conf

auth_type = password

user_domain_name = Default
project_name = service
username = glance
password = 000000

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

开启服务

[root@controller ~]# systemctl enable openstack-glance-api.service
[root@controller ~]# systemctl start openstack-glance-api.service
[root@controller ~]# netstat -natp | grep 9292

赋予服务对存储设备的可写权限

[root@controller ~]# chown -hR glance:glance /var/lib/glance/

镜像导入

导入一个cirros镜像做验证测试，没有此镜像的点击此链接获取百度云盘 提取码：46mb

[root@controller ~]# openstack image create --file cirros-0.3.4-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros

查看Openstack现有镜像

方法1：
[root@controller ~]# openstack image lis
方法2：
[root@controller ~]# glance image-list
