准备资料

OpenStack官方文档：https://docs.openstack.org/install-guide/

使用Packstack一键部署OpenStack的方式，隐藏了技术细节，如果使用中出来任何问题，我们都无法解决，所以体验完OpenStack的日常界面操作后，后期还是要仔细查看官方文档，然后一步步手工安装OpenStack各组件。

部署过程

修改centos系统的主机名

hostnamectl set-hostname openstack

设置centos系统为静态IP地址

#注意修改自己的网卡配置文件
vi /etc/sysconfig/network-scripts/ifcfg-ens32
#重启网络服务
systemctl restart network
#验证IP地址
ip addr

添加主机hosts记录

echo "172.17.2.60 openstack" >> /etc/hosts
#验证修改结果
more /etc/hosts

设置本机SSH免密码登录

#生成ssh密钥
ssh-keygen
#添加密钥信息到~./ssh/know_hosts文件
ssh-copy-id root@172.17.2.60

关闭防火墙

systemctl stop firewalld
systemctl disable firewalld
#查看防火墙状态
systemctl status firewalld

关闭SeLinux

setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

#c
 systemctl status firewalld
  getenforce

关闭NetworkManager服务

systemctl stop NetworkManager
systemctl disable NetworkManager
#查看NetworkManager状态
systemctl status NetworkManager

修改官方yum源为阿里云yum源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
#重建本地yum索引缓存
yum makecache

系统升级

#升级
yum -y update
#重启
reboot

安装常用软件

 yum -y install vim bash-completion yum-utils

安装OpenStack Stein的yum库

yum -y install centos-release-openstack-stein

修改CentOS-OpenStack-stein.repo配置文件

cd /etc/yum.repos.d/
#备份
cp -a CentOS-OpenStack-stein.repo CentOS-OpenStack-stein.repo.bak

#修改配置文件
vim CentOS-OpenStack-stein.repo
[centos-openstack-stein]
baseurl=http://mirrors.aliyun.com/$contentdir/$releasever/cloud/$basearch/openstack-stein/
#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=cloud-openstack-stein
...

#清除本地yum索引缓存，然后再重建索引缓存
yum clean all && yum makecache

安装packstack工具

yum -y install openstack-packstack

安装OpenStack allinone

packstack --allinone

自动化安装时间很长，静静等待，直到出现如下信息，表示成功安装。

查看Dashboard web页面的登录账号及密码

cat keystonerc_admin 
unset OS_SERVICE_TOKEN
    export OS_USERNAME=admin		#Dashboard登录账号
    export OS_PASSWORD='12b2ca7e963242ae'	#Dashboard登录密码
    export OS_REGION_NAME=RegionOne
    export OS_AUTH_URL=http://172.17.2.60:5000/v3
    export PS1='[\u@\h \W(keystone_admin)]\$ '
    
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_IDENTITY_API_VERSION=3

Dashboard web登录界面

登录方式：http://172.17.2.60

修改Dashboard登录密码

使用新密码重新登录

为以后的实验过程，同时需要修改keystonerc_admin文件中的OS_PASSWORD变量，换成新密码，如下：

vim keystonerc_admin
export OS_PASSWORD='admin'	#填入修改后的新密码

附：安装过程中的错误及解决办法

错误1：ERROR : Failed to run remote script, stdout:

stderr: Warning: Permanently added ‘172.17.2.60’ (ECDSA) to the list of known hosts.

解决办法：

ssh-kengen
ssh-copy-id root@172.17.2.60

错误2：facter: error while loading shared libraries: leatherman_curl.so.1.3.0: cannot open shared object file: No such file or directory

原因：启用了epel库导致的

解决办法：

#1.禁用epel
yum-config-manager --disable epel
#2.清理yum索引缓存
yum clean all
#3.重建yum索引缓存
yum makecache
#4.降级leatherman
yum downgrade leatherman
