Openstack是一个云平台管理的项目，它不是一个软件。这个项目由几个主要的组件组合起来完成一些具体的工作。Openstack是一个旨在为公共及私有云的建设与管理提供软件的开源项目。

一、安装环境

1.无网络使用该命令

nmcli c reload; sleep 3; nmcli c up ens33

2.修改主机名

hostnamectl set-hostname openstack.alione.loca

3.配置hosts解析

vim /etc/hosts192.168.241.11 openstack openstack.alione.local

4.配置本机免密

生成密钥ssh-keygen对本机进行免密ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.241.11

5.关闭防火墙和SElinux策略

sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config; setenforce 0; systemctl stop firewalld; systemctl disable firewalld

6.关闭NewworkManager

Centos7中有两种网络模式，避免冲突，在安装完OpenStack后开启

systemctl stop NetworkManager; systemctl disable NetworkManager

7.修改yum源

7.1下载阿里源

curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo

7.2清空并加载缓存yum源

yum clean all; yum makecache

8.安装基本工具

yum install -y bash-completion vim telnet bridge-utils yum-utilsbash

9.系统升级

yum -y updatereboot

10.安装OPenStack的yum仓库

yum install centos-release-openstack-train -y

11.修改OPenStack仓库Repo文件

cd /etc/yum.repos.dcp CentOS-OpenStack-train.repo{,.bak}vim CentOS-OpenStack-train.repobaseurl=http://mirrors.aliyun.com/$contentdir/$releasever/cloud/$basearch/openstack-train/#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=cloud-openstack-trainyum clean all; yum makecache

12.安装PackStack工具

yum install -y openstack-packstack

13.安装OpenStack-allinone

packstack --allinone

二、安装完成后步骤

如下图：安装完成后会显示web登陆地址，http://192.168.241.11/dashboard

账号密码在：keystonerc_admin这个文件夹中

三、基本操作命令

source keystonerc_adminglance image-listneutron agent-listnova service-listcinder service-list

1.数据库

# systemctl start mysqld# systemctl enable mysqld# systemctl status mysqld#mysql> show status like 'wsrep_%'; # 查看集群状态

2.HAproxy

# systemctl start haproxy.service# systemctl stop haproxy.service# systemctl restart haproxy.service# systemctl enable haproxy.service

3.Pacemker

# systemctl start pcsd.service# systemctl enable pcsd.service# systemctl status pcsd.service# pcs status# pcs cluster standby node# pcs cluster unstandby node# pcs resource restart haproxy #重启haproxy 资源# pcs resource cleanup #清除错误日志后重启所有资源

4.Chrony

# systemctl restart chronyd.service# chronyc sources #同步时间

5.Ceph

# ceph -s# ceph health detail# ceph osd pool create pool_name gp_num pgp_num #创建池

6.http、Keystone

# systemctl start httpd# systemctl enable httpd# systemctl status httpd

7.Rabbitmq

# systemctl enable rabbitmq-server.service# systemctl start rabbitmq-server.service# systemctl status rabbitmq-server.service -l# rabbitmqctl cluster_status# http://rabbitmq-server-IP:15672 #web访问

8.Memcache

# systemctl enable memcached.service# systemctl start memcached.service

9.OpenStack查看命令

# openstack catalog list# openstack endpoint list# openstack service list# openstack domain list# openstack image list# openstack host list

10.Glance

# systemctl enable openstack-glance-api.service openstack-glance-registry.service# systemctl start openstack-glance-api.service openstack-glance-registry.service# openstack image delete image-ID #删除镜像

11.Nova-Controller

# systemctl enable openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service# systemctl start openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service# systemctl status openstack-nova-api.service openstack-nova-consoleauth.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service

12.Nova-Computer

# systemctl enable libvirtd.service openstack-nova-compute.service# systemctl start libvirtd.service openstack-nova-compute.service
