目的

1.  配置 openstack 可用的 rabbitmq
2.  rabbitmq 用于存储 openstack 消息队列
3.  rabbitmq 作为数据存储中心
4.  openstack i 版中, rabbitmq 为 cinder, nova, neutron 组件进行数据存储,
5.  openstack h 版使用的是 qpid 进程, 经常出现进程队列堵塞现象, 导致无法创建新虚拟机

安装

yum install rabbitmq-server

启动

service rabbitmq-server start

配置

安装 rabbitmq 后, 默认创建 guest/guest 用户与密码, 可以利用下面方法修改密码

#  rabbitmqctl change_password guest openstack
Changing password for user "guest" ......done.

修改密码后, 为 cinder 添加虚拟主机

# rabbitmqctl add_vhost cinder
Creating vhost "cinder" ......done.

为其他服务创建虚拟用户

# rabbitmqctl add_user cinder openstack
Creating user "cinder" ......done.

# rabbitmqctl add_user nova openstack
Creating user "nova" ......done.

# rabbitmqctl add_user neutron openstack
Creating user "neutron" ......done.

为上述用户添加对资源的读写权限

# rabbitmqctl set_permissions cinder ".*" ".*" ".*"
# rabbitmqctl set_permissions nova ".*" ".*" ".*"
# rabbitmqctl set_permissions neutron ".*" ".*" ".*"

校验

可用下面命令进行信息校验

# rabbitmqctl report
