在CentOS 7部署配置OpenStack Juno(ml2+vlan)版ALLINONE环境
Version=Juno-2014.2.1 CentOS 7 minimal
作者：易明(oyym) QQ：517053733
本部署配置测试采用CentOS 7最小化安装操作系统部署配置OpenStack Juno版ALL-IN-ONE环境，在部署配置过程中极有可能出现配置错误又找不出错误出现在哪里，需要重新搭建测试环境，因此采用搭建虚拟机测试环境，虚拟机环境有很多好处：
- 可以随时拷贝备份，例如配置完成基础环境备份，每成功部署一个组件就备份一次而下面的部署配置出现错误可以回滚到最近的备份，避免全部推倒重来。
- 我们可以利用的物理服务器网卡资源有限，有些部署测试模拟起来可能非常麻烦，而虚拟机可以构建任意数量的虚拟网卡设备，想要几个就配置几个，很爽
以上图例中的VM(CentOS7)就是下面用来部署测试OpenStackJuno-2014.2.1云平台的虚拟机。虚拟机需要预留一个分区用于配置LVM后端块存储服务。如果虚拟机文件没有预留分区可以采用qemu-img resize命令扩展空间vda空间用于创建新的分区。
OpenStack Juno版本有11个核心组件，本次部署测试组件不包括独立性比较强的对象服务组件(Swfit)，数据库服务组件(Trove)，还有刚刚加入核心组件大家庭的大数据服务组件(Sahara)。在本次测试过程中部署8个核心组件，认证服务组件(Keystone)，镜像管理服务组件(Glance，后端采用File模式)，网络服务组件(Neutron，采用ml2+vlan模式)，计算服务组件(Nova)，块存储服务组件(Cinder，后端采用LVM)，WebUI管理服务组件(Horizon)，计量服务组件(Ceilometer)，编配组件(Heat)。说明了部署配置目标，下面开始进行对虚拟机进行一系列的部署配置。
第一节：基础环境部署配置
虚拟机操作系统为CentOS 7 X86_64 最小化安装，如下进行基本系统配置与网络配置，1. 开启软件包缓存机制，缓存下来的软件包用于制作自定义YUM源
vi /etc/yum.conf
[main]
...
cachedir=/var/cache/yum/packages
keepcache=1vi /etc/sysconfig/network-scripts/ifcfg-eth0 #管理网络，其他参数不变
DEVICE=eth0
NAME=eth0
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=static
IPADDR=172.16.100.101
PREFIX=24
vi /etc/sysconfig/network-scripts/ifcfg-eth1 #外部网络，其他参数不变
DEVICE=eth1
NAME=eth1
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
vi /etc/sysconfig/network-scripts/ifcfg-eth2 #数据(业务网络)，其他参数不变，ALL-IN-ONE环境该网口可以没有
DEVICE=eth2
NAME=eth2
TYPE=Ethernet
ONBOOT=yes
BOOTPROTO=none
vi /etc/hosts
...
172.16.100.101 controller controller.domain.com
vi /etc/hostname
controller.domain.com
#重新ssh登录，可以看到主机名称已经变更
[root@controller ~]# vi /etc/NetworkManager/NetworkManager.conf
[main]
...
dns=none
<strong>systemctl restart NetworkManager.service </strong>
vi /etc/resolv.conf
...
nameserver 114.114.114.114
nameserver 8.8.8.8
#验证域名解析服务器是否配置成功
ping www.baidu.com
PING www.a.shifen.com (115.239.211.112) 56(84) bytes of data.

bind-address = 172.16.100.101
b. 编辑[mysqld]部分调优mysql服务，设置字符集为UTF-8
[mysqld]

以上即为本次测试安装部署配置全部过程，希望能对关注者有所帮助。大家都知道OpenStack Juno版本有11个核心组件之多，本次测试部署了其中的8个核心组件，没有测试的组件包括对象存储服务组件Swift，数据库服务组件Trove，以及新加入的大数据服务组件Sahara。这三个组件部署测试将下后续的文章中补充。本次测试的8个核心组件运行良好，但是也有不足之处：
- 本次测试没有配置服务HA模式，包括OpenStack组件服务本身具有的HA模式，如dhcp-agent的active-active模式、l3-agent的active-passive模式等；
- glance的后端采用的是file模式，且提供给glance存储的设备为系统磁盘下的一个目录，不具有生产性，可以考虑采用其他存储模式或安全方案；
- cinder的存储后端采用的是LVM模式，可以考虑多种存储后端，将在随后的文章集成Ceph分布式存储系统作为cinder的其中一个的后端
- nova的存储后端也是采用的本地磁盘目录，nova存储后端可以考虑分布式文件系统如GlusterFS，NF或者采用统一存储系统Ceph
在文档的开始部分提到开启yum缓存软件包的模式，采用缓存下来的软件包制作自定义OpenStack Juno版YUM安装源，以利于在没有Internet网络的环境下安装配置OpenStack环境，节省流量，加快安装效率，固定安装版本。下一篇博文将描述如何在CentOS7上为CentOS7系统制作Openstack Juno版YUM安装源
