一、安装方式
openstack安装方法有很多种，其中有手动一步一步安装，fuel安装，devstack安装，rdo安装，RDO是红帽的的一个开源项目，能够帮我们快速部署openstack开发环境，官方部署文档：https://www.rdoproject.org/install/packstack/
二、测试环境
环境使用vmware进行测试，内存12G，处理器为4，磁盘50G，2块网卡，一块为net，一块为仅主机模式。开启支持虚拟化
三、基本配置
配置net网卡与仅主机网卡，配置完成后可以连接外网
vi /etc/sysconfig/network-scripts/ifcfg-ens33 vi /etc/sysconfig/network-scripts/ifcfg-ens37
修改主机名，关闭防火墙，selinux
hostnamectl set-hostname rdo-openstack systemctl stop firewalld.service systemctl disable firewalld.service firewall-cmd --state sed -i '/^SELINUX=.*/c SELINUX=disabled' /etc/selinux/config sed -i 's/^SELINUXTYPE=.*/SELINUXTYPE=disabled/g' /etc/selinux/config grep --color=auto '^SELINUX' /etc/selinux/config setenforce 0 #vi /etc/environment LANG=en_US.utf-8 LC_ALL=en_US.utf-8 #vi /etc/hosts 192.168.40.161 rdo-openstack 重启 reboot
四、安装
sudo yum update -y sudo yum install -y centos-release-openstack-train sudo yum update -y sudo yum install -y openstack-packstack sudo packstack --allinone
五、报错记录
在执行sudo packstack --allinone时报错（看日志最下面一行）# packstack --answer-file=train.conf
问题一
facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory
解决：
从打印信息看，是leatherman rpm包版本问题
已经安装版本是1.10.0-1
# yum list | grep leatherman leatherman.x86_64 1.10.0-1.el7 @epel leatherman-devel.x86_64 1.10.0-1.el7 epel
而facter需要1.3.0
# facter -p facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file
回退leatherman版本
# yum downgrade leatherman
问题解决
# facter -p

看网友说是：没有安装Neutron编译安装需要的python依赖包，依赖包：python-networking-bigswitch
没找到python-networking-bigswitch rpm包
最终把python2升级为python3也没解决
完成后将会输出以下内容

至此使用RDO安装openstack完成
