Controller 节点：
1、安装 NTP 服务：
# yum install chrony
# vi /etc/chrony.conf
server 0.centos.pool.ntp.org iburst
server 1.centos.pool.ntp.org iburst
server 2.centos.pool.ntp.org iburst
server 3.centos.pool.ntp.org iburst
…
allow 192.100.10.0/24
…
# systemctl enable chronyd.service 开机启用 NTP
# systemctl start chronyd.service 开启 NTP 服务
验证 NTP 服务：
# chronyc sources
210 Number of sources = 2

2、安装 Openstack 相关库
# yum install centos-release-openstack-queens 安装 Openstack 库
# yum upgrade 更新包
# yum install python-openstackclient 安装 Openstack 客户端
# yum install openstack-selinux 安装 openstack-selinux 用来管理 Openstack 服务的安全策略
3、关闭防火墙
# systemctl stop firewalld 关闭防火墙服务
# systemctl disable firewalld 永久防火墙开机自启动
4、关闭 selinux 服务
# setenforce 0 关闭 selinux 服务
# vi /etc/selinux/config 永久关闭 selinux 服务
SELINUX=disabled
5、安装数据库服务
# yum install mariadb mariadb-server python2-PyMySQL
# vi /etc/my.cnf.d/openstack.cnf
[mysqld]
bind-address = 192.100.10.160
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
# systemctl enable mariadb.service 开机启用 Mysql 服务
