基于OpenStack构建企业私有云（3）Glance配置搭建

1.安装Glance

[root@linux-node1 ~]# yum install -y openstack-glance

2.Glance数据库配置

Glance-api.conf

[root@linux-node1 ~]# vim /etc/glance/glance-api.conf

[database]

connection= mysql+pymysql://glance:glance@192.168.56.11/glance

glance-registry.conf

[root@linux-node1 ~]# vim /etc/glance/glance-registry.conf

[database]

connection= mysql+pymysql://glance:glance@192.168.56.11/glance

3.设置Keystone

[root@linux-node1 ~]# vim /etc/glance/glance-api.conf

[keystone_authtoken]

auth_uri = http://192.168.56.11:5000

auth_url = http://192.168.56.11:35357

memcached_servers = 192.168.56.11:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = glance

[paste_deploy]

flavor=keystone

glance-registry.conf配置

[root@linux-node1 ~]# vim /etc/glance/glance-registry.conf

[keystone_authtoken]

auth_uri = http://192.168.56.11:5000

auth_url = http://192.168.56.11:35357

memcached_servers = 192.168.56.11:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = glance

password = glance

[paste_deploy]

flavor=keystone

4.设置Glance镜像存储

[root@linux-node1 ~]# vim /etc/glance/glance-api.conf

[glance_store]

stores = file,http

default_store=file

filesystem_store_datadir=/var/lib/glance/images/

5.同步数据库

[root@linux-node1 ~]# su -s /bin/sh -c "glance-manage db_sync" glance

6.启动Glance服务

# systemctl enable openstack-glance-api.service

# systemctl enable openstack-glance-registry.service

# systemctl start openstack-glance-api.service

# systemctl start openstack-glance-registry.service

7.Glance服务注册

   想要让别的服务可以使用Glance，就需要在Keystone上完成服务的注册。注意需要先source一下admin的环境变量。

[root@linux-node1 ~]# source admin-openstack.sh

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

# openstack endpoint create --region RegionOne   image public http://192.168.56.11:9292

# openstack endpoint create --region RegionOne   image internal http://192.168.56.11:9292

# openstack endpoint create --region RegionOne   image admin http://192.168.56.11:9292

8.测试Glance状态

[root@linux-node1 ~]# source admin-openstack.sh

[root@linux-node1 ~]# openstack image list

9.Glance镜像

在刚开始实施OpenStack平台阶段，如果没有制作镜像。可以使用一个实验的镜像进行测试，这是一个小的Linux系统。

[root@linux-node1 ~]# cd /usr/local/src

[root@linux-node1 src]# wget http://download.cirros-cloud.n ... k.img

[root@linux-node1 src]# openstack image create "cirros" --disk-format qcow2 \

--container-format bare --file cirros-0.3.5-x86_64-disk.img --public

[root@linux-node1 src]# openstack image list
