本篇文章是本系列的第三篇文章，将继续进行OpenStack镜像服务的安装
四、安装镜像服务
4.1 （控制节点）配置镜像数据库
连接数据库
1# mysql -u root -pfuai123
创建glance数据库并设置访问权限
1MariaDB [(none)]> CREATE DATABASE glance;
2
3MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' \
4 IDENTIFIED BY 'fuai123';
5
6MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' \
7 IDENTIFIED BY 'fuai123';
4.2 （控制节点）创建glance认证相关信息
设置admin环境变量
1# . admin-openrc
创建glance用户
密码我设置的fuai123
1# openstack user create --domain default --password-prompt glance
2
3User Password:
4Repeat User Password:

4.3 （控制节点）安装软件包并配置配置文件
安装软件包
1# yum install openstack-glance -y
编辑/etc/glance/glance-api.conf文件并完成下面配置
1[database]
2connection = mysql+pymysql://glance:fuai123@controller/glance
3...
4
5[keystone_authtoken]
6auth_uri = http://controller:5000
7auth_url = http://controller:5000
8memcached_servers = controller:11211
9auth_type = password
10project_domain_name = Default
11user_domain_name = Default
12project_name = service
13username = glance
14password = fuai123
15...
16
17[paste_deploy]
18flavor = keystone
19...
20
21[glance_store]
22stores = file,http
23default_store = file
24filesystem_store_datadir = /var/lib/glance/images/
25...
编辑/etc/glance/glance-registry.conf文件，完成以下配置
1[database]
2connection = mysql+pymysql://glance:fuai123@controller/glance
3...

15...
16
17[paste_deploy]
18flavor = keystone
19...同步数据库
1# su -s /bin/sh -c "glance-manage db_sync" glance
4.4 （控制节点）设置服务的开机自启动，并启动服务
设置服务自启，并启动服务
1# systemctl enable openstack-glance-api.service \
2 openstack-glance-registry.service
3# systemctl start openstack-glance-api.service \
4 openstack-glance-registry.service
4.5 （控制节点）验证操作
- 设置环境变量
1# . admin-openrc
下载镜像
1# yum install wget -y
2# wget http://download.cirros-cloud.net/0.3.5/cirros-0.3.5-x86_64-disk.img
上传镜像
1# openstack image create "cirros" \
2 --file cirros-0.3.5-x86_64-disk.img \
