一、OpenStack安装
安装一个初始化的Mitaka版本的OpenStack环境用于分析，neutron源码
| 序号 | 角色 | IP地址 | 版本 |
| 1 | controller | 172.16.15.161 | mitaka |
| 2 | compute01 | 172.16.15.162 | mitaka |
| 3 | compute02 | 172.16.15.163 | mitaka |
开始安装吧
# 所有节点全部执行
使用本次安装教程，会安装ceilometer+gnocchi集成、heat、FWAAS、VPNAAS、LBAASv1等 # 所有节点全部执行 mkdir /etc/yum.repos.d/bak mv /etc/yum.repos.d/*repo /etc/yum.repos.d/bak cat >> /etc/yum.repos.d/openstack-mitaka.repo << EOF [base] name=CentOS-$releasever - Base baseurl=http://172.20.2.44/base enabled=1 gpgcheck=0 [mitaka] name=mitaka baseurl=http://172.20.2.44/openstack-mitaka enabled=1 gpgcheck=0 [epel] name=epel baseurl=http://172.20.2.44/epel enabled=1 gpgcheck=0 EOF yum clean all yum install python-cheetah python-gnocchi python-nova libvirt libvirt-devel libvirt-client -y
