# OpenStack-Quick

---

# Controller
## 網路設定

$ sudo su
$ echo nameserver 8.8.8.8 > /etc/resolv.conf

## 設定檔

$ git clone https://github.com/TitanLi/CloudNative.git

## Network
1. 編輯/etc/network/interfaces
The provider network interface

auto INTERFACE_NAME(第二張網卡)
iface INTERFACE_NAME(第二張網卡) inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down

2. 編輯/etc/hosts

127.0.0.1 localhost
10.0.1.97 controller
10.0.1.98 compute1

# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts

## OpenStack packages
OpenStack Queens for Ubuntu 16.04 LTS：

$ apt install software-properties-common -y
$ add-apt-repository cloud-archive:queens
$ apt update && apt dist-upgrade -y
$ apt install python-openstackclient -y

## SQL database
1. Install the packages

$ apt install mariadb-server python-pymysql -y

2. 新增檔案/etc/mysql/mariadb.conf.d/99-openstack.cnf

[mysqld]
bind-address = 10.0.1.97

default-storage-engine = innodb
innodb_file_per_table = on
max_connections = 4096
collation-server = utf8_general_ci
character-set-server = utf8

3. 重啟Database服務

$ service mysql restart

4. 安全性設定

$ mysql_secure_installation

1. Enter current password for root (enter for none)：輸入root密碼，第一次設定時預設值是空的，所以直接按Enter即可，接著會詢問是否要設定root密碼，輸入「Ｎ」

2. Remove anonymous users? [Y/n]：是否要移除匿名使用者？輸入「N」

3. Disallow root login remotely? [Y/n]：是否要關閉root遠端登入的功能？依自己需求決定，一般基於安全性考量，輸入「N」

4. Remove test database and access to it? [Y/n]：是否要移除測試的資料庫？建議選擇「Y」來移除

5. Reload privilege tables now? [Y/n]：是否要重新載入表格權限？建議選擇「Y」

## Message queue

$ apt install rabbitmq-server -y
$ rabbitmqctl add_user openstack RABBIT_PASS
$ rabbitmqctl set_permissions openstack ".*" ".*" ".*"

## Memcached

$ apt install memcached python-memcache

編輯/etc/memcached.conf檔案

-l 10.0.1.97

$ service memcached restart

## Etcd(可選擇)

$ apt install etcd -y

編輯/etc/default/etcd

ETCD_NAME="controller"
ETCD_DATA_DIR="/var/lib/etcd"
ETCD_INITIAL_CLUSTER_STATE="new"
ETCD_INITIAL_CLUSTER_TOKEN="etcd-cluster-01"
ETCD_INITIAL_CLUSTER="controller=http://10.0.1.97:2380"

ETCD_LISTEN_PEER_URLS="http://0.0.0.0:2380"
ETCD_LISTEN_CLIENT_URLS="http://10.0.1.97:2379"

> controller node IP

$ systemctl enable etcd
$ systemctl start etcd
