### OpenStack 运维 - 部署Glance组件 ###

*  一、创建数据库实例和数据库用户
 *  二、创建用户修改配置文件
 *  三、创建镜像服务API
 *  四、安装OpenStack-glance
 *  五、修改glance配置文件
 *  六、初始化glance数据库
 *   *  ① 开启服务
     *  ② 查看端口
     *  ③ 赋予glance服务的读写权限
 *  七、导入镜像
 *   *  ① 查看镜像

# 一、创建数据库实例和数据库用户 #

mysql -u root -p
    
    create database glance;
    
    grant all privileges on glance.* to 'glance'@'localhost' identified by 'GLANCE_DBPASS';
    
    grant all privileges on glance.* to 'glance'@'%' identified by 'GLANCE_DBPASS';
    
    flush privileges;
    
    exit

# 二、创建用户修改配置文件 #

#创建用户
    openstack user create --domain default --password GLANCE_PASS glance	
    
    #添加服务和用户权限glance为管理员
    openstack role add --project service --user glance admin
    
    #创建新的服务类型镜像
    openstack service create --name glance --description "OpenStack Image" image
    
    openstack service list

# 三、创建镜像服务API #

使用三种API端点代表三种服务：admin、internal、public

openstack endpoint create --region RegionOne image admin http://ct:9292
    
    openstack endpoint create --region RegionOne image internal http://ct:9292
    
    openstack endpoint create --region RegionOne image public http://ct:9292

# 四、安装OpenStack-glance #

yum -y install openstack-glance

# 五、修改glance配置文件 #

配置文件：`glance-api.conf` 、 `glance-registry.conf`

cp -a /etc/glance/glance-api.conf{
        ,.bak}
    grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf
    
    openstack-config --set /etc/glance/glance-api.conf database connection mysql+pymysql://glance:GLANCE_DBPASS@ct/glance
    openstack-config --set /etc/glance/glance-api.conf keystone_authtoken www_authenticate_uri http://ct:5000
    openstack-config --set /etc/glance/glance-api.conf keystone_authtoken auth_url http://ct:5000
    openstack-config --set /etc/glance/glance-api.conf keystone_authtoken memcached_servers ct:11211

# 六、初始化glance数据库 #

su -s /bin/sh -c "glance-manage db_sync" glance

## ① 开启服务 ##

systemctl enable openstack-glance-api
    systemctl start openstack-glance-api

## ② 查看端口 ##

netstat -natp | grep 9292

## ③ 赋予glance服务的读写权限 ##

chown -hR glance:glance /var/lib/glance/

# 七、导入镜像 #

openstack image create --file cirros-0.3.5-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros
