OpenStack安装笔记三

之前安装了Identity Service
接下来试下Image service – glance installation for Pike

Prerequisites

• 创建MySQL数据库
• 创建MySQL用户
• 创建galance用户并授权
• 创建API

Install and configure components

修改好openstack-glance两个配置文件/etc/glance/glance-api.conf 和 /etc/glance/glance-registry.conf后，执行命令

[root@controller ~]# su -s /bin/sh -c "glance-manage db_sync" glance
/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:1330: OsloDBDeprecationWarning: EngineFacade is deprecated; please use oslo_db.sqlalchemy.enginefacade
  expire_on_commit=expire_on_commit, _conf=conf)

INFO  [alembic.runtime.migration] Will assume non-transactional DDL.
Upgraded database to: pike01, current revision(s): pike01

设置开机启动及启动服务openstack-glance-api
完成

继续完成

• Compute service – nova installation for Pike

当前版本为
nova 16.1.8.dev9

Overview有点多，后面有时间再慢慢看，直接进入安装环节
Install and configure controller node for Red Hat Enterprise Linux and CentOS

创建数据库

MariaDB [(none)]> CREATE DATABASE nova_api;
MariaDB [(none)]> CREATE DATABASE nova;
MariaDB [(none)]> CREATE DATABASE nova_cell0;

进行授权

GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';

官网上是多行，整理成一行后贴在这里，注意修改语句中的密码信息

修改nova配置文件/etc/nova/nova.conf 这个文件修改处有点多，参照官网文档修改

在执行Populate the nova database:时出现如下输出，（网上查阅此输出并不是报错）

su -s /bin/sh -c "nova-manage db sync" nova
/usr/lib/python2.7/site-packages/pymysql/cursors.py:166: Warning: (1831, u'Duplicate index `block_device_mapping_instance_uuid_virtual_name_device_name_idx`. This is deprecated and will be disallowed in a future release.')
  result = self._query(query)
/usr/lib/python2.7/site-packages/pymysql/cursors.py:166: Warning: (1831, u'Duplicate index `uniq_instances0uuid`. This is deprecated and will be disallowed in a future release.')
  result = self._query(query)

状况未知，待查，后续检查的命令执行结果如下

nova-manage cell_v2 list_cells

开启并启动服务，执行完毕，接下来该安装计算节点了，明天继续:)
