一、部署基础环境：
A.IP地址规划：
controller节点：192.168.0.201，compute节点：192.168.0.202
B.关闭防火墙Firewalld（所有节点）
systemctl disable firewalld.service
systemctl stop firewalld.service
C.禁止Selinux内核安全机制（所有节点）
vim /etc/sysconfig/selinux
SELINUX=disabled
D.配置固定IP地址（所有节点）
ens33（外网地址）；ens37（内网地址）
controller：ens37 192.168.0.201
compute：ens37 192.168.0.202
二、构建企业私有云平台实施步骤如下：
1. 配置hosts和hostname(controller和compute节点)
vi /etc/hostname(controller节点)
controller
vi /etc/hostname(compute节点)
compute
vi /etc/hosts（controller和compute节点）
192.168.0.201 controller
192.168.0.202 compute
2. 配置NTP(controller和compute节点)
在controller节点配置
下载：yum -y install chrony
配置：vi /etc/chrony.conf
allow 192.168.0.0/24
server ntp1.aliyun.com iburst
启动
systemctl enable chronyd.service
systemctl start chronyd.service
验证
chronyc sources
在compute节点配置
下载：yum -y install chrony
配置：vi /etc/chrony.conf(删除所有内容)
server controller iburst
启动
systemctl enable chronyd.service
systemctl start chronyd.service
验证
chronyc sources
3. 使用阿里云官方YUM源(所有节点)注：本操作跳过
备份
cd /etc/yum.repo.d/
mkdir bak
mv C* ./bak
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak

default-storage-engine = innodb
innodb_file_per_tablemax_connections =4096
collation-server = utf8_general_ci
character-set-server = utf8
启动
systemctl enable mariadb.service

OPTIONS="-l 127.0.0.1,::1,controller"
启动
systemctl enable memcached.service
systemctl start memcached.service
6. 安装Etcd(仅controller节点)这是一个分布式的可靠键值存储，用于分布式密钥锁定、存储配置、跟踪服务的实时状态和其他场景
下载
yum -y install etcd

vi /etc/etcd/etcd.conf
#[Member]
ETCD_DATA_DIR="/var/lib/etcd/default.etcd"
ETCD_LISTEN_PEER_URLS="http://192.168.0.201:2380"
ETCD_LISTEN_CLIENT_URLS="http://192.168.0.201:2379"

ETCD_INITIAL_CLUSTER_STATE="new"
启动
systemctl enable etcd
systemctl start etcd
7. 身份服务（仅controller节点）
数据库
登录mysql -uroot -p123456
注：如果显示 1045报错,那么执行以下操作
停服务：systemctl stop mariadb.service
启动服务：mysqld_safe --user=mysql --skip-grant-tables --skip-networking &
登录：mysql -u root mysql
改密码：UPDATE user SET PASSWORD=PASSWORD('123456') where USER='root';
FLUSH PRIVILEGES;
退出：quit
创建数据库keystone
