openstack搭建8、部署glance镜像服务
8、部署glance镜像服务
8.1 配置MariaDB数据库中的glance用户和权限等
注：由于是集群，所以只要在一个控制节点上创建即可
[root@controller1:/root]# mysql -uroot -p"123456" MariaDB [(none)]> CREATE DATABASE glance; Query OK, 1 row affected (0.009 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY 'GLANCE_szh'; Query OK, 0 rows affected (0.010 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY 'GLANCE_szh'; Query OK, 0 rows affected (0.010 sec) MariaDB [(none)]> flush privileges; MariaDB [(none)]> exit Bye
8.2 创建glance api
