Openstack组件部署 — Overview和前期环境准备

控制节点是整个Openstack控制枢纽，可以将Database、Message queue、DNS、NTP、Keystone等服务集成到一起，当然Openstack实现了松耦合的架构思想，因此所有的组件都可以在任意Node中安装组合，视乎实际情况而定。

step1.

**Step2.**Edit the config file.

**Step3.**Forward Domain

vim /etc/named.rfc1912.zones

Create zone config file:

vim /var/named/jmilk.com.zone

vim /etc/resolv.conf

注意：当需要联网安装软件包时，还是需要将DNSSERVER指向外网DNSSERVER

Restart the named service：

Install the packages:

Edit the /etc/chrony.conf:

vim /etc/chrony.conf

Start the NTP service and configure it to start when the system boots:

CHECK:

Create and edit the /etc/my.cnf.d/openstack.cnf file

vim /etc/my.cnf.d/openstack.cnf

Start the database service and configure it to start when the system boots:

初始化MySQL：

OpenStack使用message queue实现协调操作和服务之间的状态信息。Message queue service一般在Controller Node上运行。

OpenStack常用的消息代理软件：

RabbitMQ(更加常用)

Qpid

ZeroMQ

Install the package:

Start the message queue service and configure it to start when the system boots:

Add the openstack user

Permit configuration, write, and read access for the openstack user:

The Identity service authentication mechanism for services uses Memcached to cache tokens. Memcached缓存技术用于对Keystone组件的认证信息token进行缓存。一般安装在Controller Node上，在生产系统中，建议使用认证、防火墙、加密的手段来保证token缓存的安全。

Start the Memcached service and configure it to start when the system boots:
