Glance镜像服务：
Glance主要由三部分构成：glance-api、glance-registry以及image store
Glance-api:接受系统镜像的创建、删除、读取请求。
Glance-Registry：云系统的镜像注册服务
Glance安装：
[root@hostnamelinux-node1 ~]# yum -y install openstack-glance python-glance python-glanceclient [root@hostnamelinux-node1 ~]# vim /etc/glance/glance-api.conf [database] connection=mysql://glance:glance@192.168.56.11/glance [root@hostnamelinux-node1 ~]# vim /etc/glance/glance-registry.conf [database] connection=mysql://glance:glance@192.168.56.11/glance
同步数据库：
[root@hostnamelinux-node1 ~]# su -s /bin/sh -c "glance-manage db_sync" glance No handlers could be found for logger "oslo_config.cfg"（可以忽略） [root@hostnamelinux-node1 ~]# mysql -uglance -pglance -h192.168.56.11 Welcome to the MariaDB monitor.
