Openstack：Queen 版安装（两个节点）
本文所有密码均为111，可以根据需要自己更改
基础环境搭建
1.环境设置
10.0.0.11 controller（2vCPU、4G内存、20G存储、双网卡）
10.0.0.31 compute（1vCPU、2G内存、20G存储、双网卡）
更换apt源：
cp /etc/apt/sources.list /etc/apt/sources.list.backup
vim /etc/apt/sources.list
deb http://mirrors.aliyun.com/ubuntu/ xenial main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial main
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates main
deb http://mirrors.aliyun.com/ubuntu/ xenial universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-updates universe
deb http://mirrors.aliyun.com/ubuntu/ xenial-security main
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security main
deb http://mirrors.aliyun.com/ubuntu/ xenial-security universe
deb-src http://mirrors.aliyun.com/ubuntu/ xenial-security universe
sudo apt-get update
2.Network Time Protocol (NTP)
Controller node
安装NTP服务
# apt install chrony
编辑/etc/chrony/chrony.conf：
server NTP_SERVER iburst
allow 10.0.0.0/24
替换NTP_SERVER和10.0.0.0/24为你需要的内容。
重启NTP服务：
# service chrony restart
Other nodes
安装NTP服务
# apt install chrony
编辑/etc/chrony/chrony.conf：
server controller iburst
注释掉pool 2.debian.pool.ntp.org offline iburst
重启NTP服务：
# service chrony restart
验证：
#chronyc sources
3.OpenStack packages(所有节点)
启用OpenStack Queens库:
# apt install software-properties-common
# add-apt-repository cloud-archive:queens
1.升级节点上的软件包：
# apt update && apt dist-upgrade
2.安装 OpenStack 客户端:
# apt install python-openstackclient
4.安装SQL数据库
1.安装软件包：
# apt install mariadb-server python-pymysql
2.创建和编辑/etc/mysql/mariadb.conf.d/99-openstack.cnf文件
[mysqld]
bind-address = 10.0.0.11
default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8
3.重启数据库服务：
# service mysql restart
4.通过运行mysql_secure_installation脚本来保护数据库服务的安全。特别是, 为数据库root帐户选择合适的密码:
# mysql_secure_installation
4.安装Message queue
1.安装软件包：
# apt install rabbitmq-server
2.添加openstak用户：
# rabbitmqctl add_user openstack 111
Creating user "openstack" ...
3.允许openstack用户进行配置、写入和读取访问:
# rabbitmqctl set_permissions openstack ".*" ".*" ".*"
Setting permissions for user "openstack" in vhost "/" ...
5.配置Memcached
1.安装软件包:
# apt install memcached python-memcache
2.编辑/etc/memcached.conf文件, 并将服务配置为使用控制器节点的管理 IP 地址。这是通过管理网络启用其他节点的访问:
-l 10.0.0.11
注意:更改已有-l 127.0.0.1的现有行.
3.重新启动 Memcached 服务:
# service memcached restart
6.Etcd
1.安装软件包：
# apt install etcd
2.编辑 /etc/etcd/etcd.conf.yml 文件并且使用管理IP设置initial-cluster, initial-advertise-peer-urls, advertise-client-urls, listen-client-urls：
name: controller
data-dir: /var/lib/etcd
initial-cluster-state: 'new'
initial-cluster-token: 'etcd-cluster-01'
initial-cluster: controller=http://10.0.0.11:2380
initial-advertise-peer-urls: http://10.0.0.11:2380
advertise-client-urls: http://10.0.0.11:2379
listen-peer-urls: http://0.0.0.0:2380
listen-client-urls: http://10.0.0.11:2379
3.创建并且编辑/lib/systemd/system/etcd.service 文件：
[Unit]
After=network.target
Description=etcd - highly-available key value store
[Service]
LimitNOFILE=65536
Restart=on-failure
Type=notify
ExecStart=/usr/bin/etcd --config-file /etc/etcd/etcd.conf.yml
User=etcd
[Install]
WantedBy=multi-user.target
4.重启服务：
# systemctl enable etcd
# systemctl start etcd
安装服务组件
Keystone-Identity service
Glance-Image service
nova-Compute service
neutron-Networking service
Dashboard
Block Storage service
由于比较懒，后面的不想整理了。。。
