OpenStack Train版搭建详解

注：本篇文章根据openstack官网进行编写，编写不易。有兴趣的可以直接去官网进行搭建

一、准备环境

01-基础环境

#本次测试为双网卡（都为net模式）和双节点部署,根据自己实际情况进行更改
controller
eth33 192.168.200.10
eth34 none
compute
eth33 192.168.200.20
eth34 none

主机名	ip地址	系统版本
controller	192.168.200.10	centos7.5.1804
compute	192.168.200.20	centos7.5.1804

02-host解析（控制，计算）

配置网卡后

[root@controller ~]# cat /etc/hosts
192.168.200.10 controller
192.168.200.20 compute

scp /etc/hosts 192.168.200.20:/etc/hosts

03-关闭防火墙和selinux（控制，计算）

##########controller#############
[root@controller ~]# systemctl stop firewalld
[root@controller ~]# systemctl disable firewalld
[root@controller ~]# vim /etc/sysconfig/selinux
SELINUX=disabled
[root@controller ~]# setenforce 0
----------------------------------------------------------------
##########compute###################
[root@compute ~]# systemctl stop firewalld
[root@compute ~]# systemctl disable firewalld
[root@compute ~]# vim /etc/sysconfig/selinux   #重启生效
SELINUX=disabled
[root@compute ~]# setenforce 0   #可以直接生效Permissive

04-准备yum源（控制，计算）

rm -rf /etc/yum.repos.d/*

------------------上外网的情况-------------------------
curl http://mirrors.163.com/.help/CentOS7-base-163.repo >> /etc/yum.repos.d/centos.repo
yum repolist  #验证
####修改yum配置文件 来获取缓存rpm包,第一次做就需要用到，来实现【第十三、扩展】的用法
vim /etc/yum.conf
keepcache=1
-------------------内网------------------------------------
将openstack-trian.tar.gz包上传到/opt/目录，解压
vi /etc/yum.repos.d/openstack.repo
[openstack]
name=openstack
baseurl=file:///opt/openstack-train/
gpgcheck=0
enabled=1

二、安装chrony服务

01-控制节点准备

yum install -y chrony

vim /etc/chrony.conf   #添加以下
server controller iburst   #配置ntp服务器
allow 192.168.200.0/16    #允许200网段的进行时间同步

systemctl restart chronyd
systemctl enable chronyd
#验证
chronyc sources

02-计算节点准备

yum install -y chrony

vim /etc/chrony.conf   #添加以下
server controller iburst

systemctl restart chronyd
systemctl enable chronyd
#验证
chronyc sources

三、安装openstack客户端

#############控制，计算节点###################

01-安装openstack库

yum install centos-release-openstack-train -y

#更新所有包
yum upgrade -y
#安装必要命令
yum install -y lsof net-tools vim wget

02-安装openstack客户端

yum install python-openstackclient openstack-selinux openstack-utils -y

centos-release-openstack-train 保证安装更新openstack版本为最新版本t版
python-openstackclient openstack的python客户端
因为openstack中的API大多数是python编写的，并且连接数据库，也需要python
openstack-selinux openstack核心安全防护
openstack-utils openstack其它util工具

四、部署数据库服务

################controller############3

01-安装mariadb服务

yum install mariadb mariadb-server python2-PyMySQL -y

02-创建并编辑配置文件

vi /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.168.200.10     #绑定ip地址，跟随自己实际情况
default-storage-engine = innodb   #将默认引擎改为innodb，来支持高级数据库功能
innodb_file_per_table = on   #修改InnoDB为独立表空间模式
max_connections = 4096    #最大连接数
collation-server = utf8_general_ci   #
character-set-server = utf8   #

03-启动并且开机自启

systemctl enable mariadb && systemctl start mariadb

04-运行安全脚本

mysql_secure_installation  #运行命令

Enter current password for root (enter for none):       #直接回车
Set root password? [Y/n] y   #设置密码
New password:               #设置密码000000
Re-enter new password:   #再次设置密码
Remove anonymous users? [Y/n] y   #是否删除匿名用户
Disallow root login remotely? [Y/n] n  #不允许远程登录
Remove test database and access to it? [Y/n] y  #删除测试数据库并访问
Reload privilege tables now? [Y/n] y   #是否重新加载特权表

五、部署消息队列

#################controller#############

01-安装rabbitmq服务

yum install rabbitmq-server -y

02-设置开机自启并启动

systemctl enable rabbitmq-server && systemctl start rabbitmq-server #端口5672

04-授予权限

rabbitmqctl set_permissions -p / openstack '.*' '.*' '.*' #配置，读，写权限

05-设置角色

rabbitmqctl set_user_tags openstack administrator #赋予管理员角色

06-安装web插件（可执行也可不执行）

rabbitmq-plugins enable rabbitmq_management #启动web管理界面

07-验证，可访问网址

netstat -nltp | grep 5672 #5672是默认端口，25672是测试工具cli端口
[http://192.168.200.10:15672](http://192.168.1.92:15672) #用户与密码为guest

export OS_IDENTITY_API_VERSION=3

11-创建相关域，项目，用户和角色

#创建demo域，不创建也行，默认存在default域，admin项目和admin用户和角色 <<<<看清楚，不需要创建
openstack domain create --description "An Example Domain" demo
#创建admin项目
openstack project create --domain demo --description "Admin Project" admin
#创建admin用户
openstack user create --domain demo --password 000000 admin
#创建admin角色

#创建软链接
ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini

#重启nova服务
systemctl restart openstack-nova-api

05-同步数据库并启动服务

#同步数据库
su -s /bin/sh -c "neutron-db-manage --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" neutron
#启动neutron服务并设置开机自启
systemctl enable neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service

systemctl restart neutron-server.service neutron-linuxbridge-agent.service neutron-dhcp-agent.service neutron-metadata-agent.service neutron-l3-agent.service

06-安装neutron网络服务并配置（计算节点）

#安装neutron服务
yum install openstack-neutron-linuxbridge ebtables ipset -y
#配置第二张网卡
vi /etc/sysconfig/network-scripts/ifcfg-ens34
#只保留这四行
DEVICE=ens34
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"

systemctl restart network


#备份并将#和空行去掉

#修改配置文件
vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini

[linux_bridge]
physical_interface_mappings = provider:ens34  #第二张网卡名字
[vxlan]
enable_vxlan = true
local_ip = 192.168.200.20
l2_population = true
[securitygroup]

auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = neutron
password = 000000

07-启动服务

#重启nova服务
systemctl restart openstack-nova-compute.service
#启动服务并设置开机自启
systemctl start neutron-linuxbridge-agent.service
systemctl enable neutron-linuxbridge-agent.service

08-验证

#查看网络插件是否启动成功
openstack network agent list

十二、部署horizon服务

01-安装服务并配置

#安装dashboard服务
yum install openstack-dashboard -y 

#修改配置文件
vim /etc/openstack-dashboard/local_settings

……
OPENSTACK_HOST = "controller"        ##配置界面在控制节点使用
……
ALLOWED_HOSTS = ['*']               ##允许所有主机访问
……
SESSION_ENGINE = 'django.contrib.sessions.backends.cache'   ##配置memcached存储服务
……
CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache',
        'LOCATION': 'controller:11211',
    },
}
……
OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST  ##启动v3的认证api
……
OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True       ##启用domain支持
……
OPENSTACK_API_VERSIONS = {              ##配置api版本
    "data-processing": 1.1,
    "identity": 3,
    "image": 2,
    "volume": 2,
    "compute": 2,
}
……
OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = 'Default'       ##配置Default为默认域

OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user"                ##配置user角色为默认角色

TIME_ZONE = "Asia/Shanghai"                         ##配置时区

#修改配置文件
/etc/httpd/conf.d/openstack-dashboard.conf

WSGIApplicationGroup %{GLOBAL}'  #第四行添加

02-重启服务

#重启httpd服务和memcached服务
systemctl restart httpd.service memcached.service

03-验证

#浏览器输入ip
http://192.168.200.10/dashboard
=============================================================================
#搭建openstack The requested URL /auth/login/ was not found on this server报错

vi /usr/share/openstack-dashboard/openstack_dashboard/local/local_settings.py

WEBROOT = '/dashboard'
==============================================================================

十三、扩展

01-将rpm包打包，可实现离线安装

###############控制节点################
yum -y install createrepo
mkdir -p /mnt/openstack/openstack_Train
cd /var/cache/yum/x86_64/7/
find ./* -name "*.rpm"  -exec cp {} /mnt/openstack/openstack_Train/ ; 
###############计算节点################
mkdir -p /mnt/openstack/openstack_Train_compute
cd /var/cache/yum/x86_64/7/
find ./* -name "*.rpm"  -exec cp {} /mnt/openstack/openstack_Train_compute/ ;
scp /mnt/openstack/openstack_Train_compute/* 192.168.200.10:/mnt/openstack/openstack_Train_compute


#到控制节点上把所有的rpm包都放到一起
cd /mnt/
mv -f openstack_Train_compute/*.rpm openstack_Train/

#创建yum
cd /mnt/openstack/openstack_Train
createrepo ./
ls repodata/

#打包
tar -zcvf openstack-train.tar.gz openstack_Train/


#这样就可以将tar包保存到本地，供以后使用
1. 将tar包上传，解压到/mnt/
2. 配置yum.repo文件，配置yum到本地目录
3. 就可以使用不需要联网下载
