Openstack CentOS6.5 ALL IN ONE 安装

2024-07-07 15:03:30   230人阅读

本文档以RDO的方式安装单节点、单网卡的Openstack。

RDO是可在Red Hat Enterprise Linux、Fedora及其变体上运行的社区支持OpenStack版本。部署简单方便，RDO中包含核心的OpenStack组件 – Nova、Glance、Keystone、Cinder、Neutron、Swift和Horizon，还有用于云应用协调的孵化项目 – Heat，以及用于资源监视和计量的Ceilometer。利用红帽开发的安装工具 – PackStack，可以实现非常简便轻松的安装过程。

RDO的ALL IN ONE安装方式主要用于测试环境，安装所需要的环境比较容易实现，生产环境推荐使用真实物理机，多节点并逐个安装各组件的方式进行。

一、安装环境：

服务器：vmware虚拟机 系统：CentOS6.5 内核版本：2.6.32-431.3.1.el6.x86_64

网卡：一块(eth0) IP:192.168.8.229 netmask:255.255.255.0 gateway：192.168.8.1(办公网络)

二、配置国内源

Shell
cd/etc/yum.repos.d/
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo
yum list

三、设置FQDN

因为RDO的安装方式是通过puppet进行安装需要用到FQDN的命名方式，所以主机名要这样设置，名字可以随意取

vim/etc/sysconfig/network
controller.domain.cc
hostname controller.domain.cc
 
[root@controller~]# hostname -f
controller.domain.cc

四、修改HOST文件

vi/etc/hosts
192.168.8.229controller.domain.cc

五、 配置cinder-volumes

给cinder-volumes单独一个分区，可以提高性能，我在安装系统的时候预留了一块分区未挂载。如果未预留，可以给虚拟机加一块硬盘做来此分区。

fdisk-l
pvcreate/dev/sda5
vgcreate cinder-volumes/dev/sda5

六、安装packstack

 
yum install-yhttp://rdo.fedorapeople.org/openstack/openstack-havana/rdo-release-havana.rpm
yum install-yopenstack-packstack
yum-yupdate
 

yum更新后重启服务器

七、关闭selinux

vi/etc/selinux/config
 
#SELINUX=enforcing
SELINUX=disabled

八、开始安装

因为我们提前配置了cinder-volumes所以在安装命令中取消cinder-volumes的配置

 packstack--allinone--provision-demo=nCONFIG_CINDER_VOLUMES_CREATE=n

九、安装过程

[root@controller~]# packstack  --allinone --provision-demo=n CONFIG_CINDER_VOLUMES_CREATE=n

安装过程中可能会因为源的问题中断，加上应答文件再次执行即可

 packstack--answer-file=/root/packstack-answers-20140121-232841.txt

安装完成后，重启服务器

十、配置网络

安装好以后配置网络

# cat /etc/sysconfig/network-scripts/ifcfg-eth0 
DEVICE=eth0
ONBOOT=yes
HWADDR=00:E0:81:D8:43:BE
TYPE=OVSPort
DEVICETYPE=ovs
OVS_BRIDGE=br-ex

ifcfg-br-ex 是一个openvswitch 的连接外网的bridge。因为RDO目前的BUG，安装后成后并没有ifcfg-br-ex被创建，需要手动新增。

# cat /etc/sysconfig/network-scripts/ifcfg-br-ex 
DEVICE=br-ex
DEVICETYPE=ovs
TYPE=OVSBridge
BOOTPROTO=static
IPADDR=192.168.8.229
NETMASK=255.255.255.0
GATEWAY=192.168.8.1
ONBOOT=yes

重启网卡

十、安装镜像

安装完成后，用户、密码以及认证地址等环境变量被保存在/root/keystonerc_admin中，命令行下执行命令的时候需要先导入此文件或写到/etc/profile中。

十一、配置安全组规则

打开tcp:22端口和icmp协议的访问权限

 
Shell
 
1
2
neutron security-group-rule-create--protocol icmp--direction ingress default
neutron security-group-rule-create--protocol tcp--port-range-min22--port-range-max22--direction ingress default
