72小時實驗-OpenStack多節點安裝設定

在<a href="">前一篇</a>的分享，筆者已將Gluster環境架設完畢，並已能正確掛載。
今天筆者將繼續架設xx部OpenStack節點伺服器，並將Gluster Storage Pool掛載使用。

將openstack2伺服器重新啟動

1.測試openstack1與openstack2可以正確連結
登入至openstack1主機
ping openstack2主機外部ip

ping 162.243.64.148

ping openstack2主機內部ip

ping 10.128.23.136

登入至openstack2主機
ping openstack1主機外部ip

ping 162.243.64.147

ping openstack1主機內部ip

ping 10.128.23.110

2.先安裝第一部OpenStack節點，相關配置如下
CentOS 6.4 x64、記憶體2GB、硬碟20GB、網路卡2片

3.安裝步驟
更新套件
yum upgrade;yum update
安裝nmap及vim(筆者常用的工具)
yum install nmap vim tcpdump

4.安裝OpenStack Havana套件來源套件庫

yum install -y http://rdo.fedorapeople.org/openstack-havana/rdo-release-havana.rpm

5.安裝Packstack套件

yum install -y openstack-packstack

6.執行Packstack開始安裝openstack套件，匯入answer-file
請登入到openstack1主機
產生multi-node.txt

packstack --gen-answer-file=multi-node.txt

修改multi-node.txt內容如下

CONFIG_NOVA_VNCPROXY_HOST=162.243.64.147
CONFIG_NOVA_COMPUTE_HOSTS=10.128.23.110,10.128.23.136

CONFIG_SWIFT_INSTALL=y
CONFIG_HEAT_INSTALL=y
CONFIG_HEAT_CFN_INSTALL=y
