Openstack搭建

一、环境准备
内存大于2G
磁盘空间大于5G
注：计算节点和控制节点不要在一起

主机名        操作系统            IP地址            备注
controller    CentOS-7.4-x86_64    172.16.10.33    控制节点
compute     CentOS-7.4-x86_64    172.16.10.35    计算节点

关闭虚拟机防火墙以及selinux
systemctl disable firewalld.service
systemctl stop firewalld.service
vim /etc/sysconfig/selinux
SELINUX=disable           //将enforcing修改为disable，永久关闭
setenforce 0

二、搭建openstack
环境准备
在接下来的操作中若无特别说明，则表示在三台主机上均进行相同操作

配置域名解析
修改主机名:
hostnamectl set-hostname 三台虚拟机都要做，然后重启生效

修改所有hosts文件
vim /etc/hosts
172.16.10.33 controller
172.16.10.35 compute
hosts文件内容一致

测试各节点连通性
ping -c 4 openstack.org     //是否ping通官网
ping -c 4 compute            //各节点间测试

配置阿里云yum源
下载最新yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
yum -y install epel-release

安装配置NTP服务
在controller节点安装配置chrony

yum install chrony -y

vim /etc/chrony.conf
server  controller  iburst  所有节点向controller节点同步时间
allow 172.16.10.0/24        设置时间同步网段
systemctl enable chronyd
systemctl restart chronyd

在compute节点安装配置chrony
yum install chrony -y

vim /etc/chrony.conf
server  controller  iburst
systemctl enable chronyd
systemctl restart chronyd

在cinder节点安装配置chrony

yum install chrony -y

vim /etc/chrony.conf
server  controller  iburst
systemctl enable chronyd
systemctl restart chronyd

验证时钟同步服务

chronyc sources

启用OpenStack库

yum install centos-release-openstack-queens -y
yum upgrade -y                                        //在主机上升级包
yum install python-openstackclient -y                   //安装openstack客户端
yum install openstack-selinux -y                       //安装openstack-selinux，便于自动管理openstack的安全策略

MySQL数据库部署（controller）

软件包安装
yum install mariadb mariadb-server python2-PyMySQL -y

配置文件修改
vim /etc/my.cnf.d/mariadb-server.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-error=/var/log/mariadb/mariadb.log
pid-file=/var/run/mariadb/mariadb.pid
bind-address = 172.16.10.33                              //修改为控制节点IP，使其他节点可以通过管理网络访问数据库
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

启动服务并设置为开机自启
systemctl enable mariadb.service
systemctl start mariadb.service

对数据库进行安全加固
mysql_secure_installation

安装配置Messaging server-RabbitMQ
OpenStack使用message queue协调操作和各服务器的状态信息。消息队列服务一般运行在控制节点上。

在controller节点安装RabbitMQ
yum install rabbitmq-server -y

开启服务并设置为开机自启
systemctl enable rabbitmq-server.service
systemctl start rabbitmq-server.service 
netstat -ntap | grep 5672

添加openstack用户

如果在添加用户时报错，就检查是否修改了主机名，或者是在之前的操作中修改主机名之后未重启，重启即可解决创建用户报错

rabbitmqctl add_user openstack 123456                     创建用户openstack，密码为123456
rabbitmqctl set_permissions openstack ".*" ".*" ".*"      授予新建用户权限

部署memcached服务（controller）

安装软件
yum install memcached python-memcached -y

修改配置文件
vim /etc/sysconfig/memcached

PORT="11211"
USER="memcached"
MAXCONN="1024"
CACHESIZE="64"
OPTIONS="-l 172.16.10.33,::1"

开启服务并设置为开机自启
systemctl enable memcached.service
systemctl start memcached.service

部署etcd服务（controller）

etcd是一个分布式，一致的键值存储，用于共享配置和服务发现，特点是，安全，具有可选客户端证书身份验证的自动TLS；
快速，基准测试10,000次/秒；可靠，使用Raft正确分发。

安装软件
yum install etcd -y

修改配置文件
vim /etc/etcd/etcd.conf

ETCD_INITIAL_CLUSTER
ETCD_INITIAL_ADVERTISE_PEER_URLS
ETCD_ADVERTISE_CLIENT_URLS
ETCD_LISTEN_CLIENT_URLS
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://172.16.10.33:2380"
ETCD_LISTEN_CLIENT_URLS="http://172.16.10.33:2379"
ETCD_NAME="controller"
#[Clustering]

ETCD_ADVERTISE_CLIENT_URLS="http://172.16.10.33:2379"
ETCD_INITIAL_CLUSTER="controller=http://172.16.10.33:2380"   
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER_STATE="new"

开启服务并设置为开机自启
systemctl enable etcd.service
systemctl start etcd.service

keystone服务的安装配置

在controller节点上操作

配置MySQL数据库及授权
