跟我一起来学OpenStack部署

一、安装环境

1、先准备一台主机，纯净版。

2、如果没网使用命令

nmcli c reload; sleep 3; nmcli c up ens33

3、修改主机名

hostnamectl set-hostname openstack.alione.loca

4、配置hosts解析

vi etc/hosts

192.168.59.149 openstack openstack.alione.local

5、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@192.168.59.149

6、关闭防火墙与selinux策略

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

7、关闭NetworkManager

centos7中有两种网络管理模式，避免冲突，在安装完opensack后可开启

systemctl stop NetworkManager; systemctl disable NetworkManager

8、修改yun源

下载阿里源

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

清空并加载缓存yum源

yum clean all; yum makecache

9、安装基本工具

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

bash

10、系统升级

yum -y update

reboot

11、安装OpenStack的yum仓库

yum install centos-release-openstack-train -y

12、修改openstack仓库repo文件

因为对网络需求大，当出现网络波动时会导致报错，最好修改为国内源进行部署

cd etc/yum.repos.d

cp CentOS-OpenStack-train.repo{,.bak}

vim CentOS-OpenStack-train.repo

baseurl=http://mirrors.aliyun.com/$contentdir/$releasever/cloud/$basearch/openstack-train/

#mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=cloud-openstack-train

yum clean all; yum makecache

13、安装packstack工具

yum install -y openstack-packstack

14、安装OpenStack-allinone

packstack --allinone

二、安装完成后步骤

1、如下图：安装完成后会显示web登陆地址，http://192.168.59.149/dashboard

账号密码在：keystonerc_admin这个文件夹中。

三、基本操作命令

source keystonerc_admin

 glance image-list

neutron agent-list

 nova service-list

 cinder 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、时间服务 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

13、neutron-controller:

# systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

# systemctl start neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

# systemctl status neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service

14、neutron-computer:

# systemctl enable neutron-linuxbridge-agent.service

# systemctl start neutron-linuxbridge-agent.service

15、dashboard:

# systemctl restart httpd.service memcached.service
