### Thiết lập cơ bản

### Enable the OpenStack repository

apt-get install software-properties-common -y
add-apt-repository cloud-archive:liberty -y


- Upgrade the packages on your host
apt-get -y update && apt-get -y dist-upgrade

- Install the OpenStack client
apt-get -y install python-openstackclient

- Reboot VM
init 6


### Install and configure the database server

- Install the packages:
apt-get -y install mariadb-server python-pymysql

- Nhập pass trong quá trình cài.

- Tạo file  /etc/mysql/conf.d/mysqld_openstack.cnf với nội dung sau

[mysqld]
bind-address = 0.0.0.0

[mysqld]
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8

- Khởi động lại MySQL

service mysql restart

### Install the message queue service
- Install the package:
apt-get -y install rabbitmq-server

-Add the openstack user
rabbitmqctl add_user openstack Welcome123
 
 
- Permit configuration, write, and read access for the openstack user

rabbitmqctl set_permissions openstack ".*" ".*" ".*"


### Install Keysonte
- Use the database access client to connect to the database server as the root user

```sh 
mysql -u root -pWelcome123

CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'Welcome123';
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY 'Welcome123';
exit;
```

- Disable the keystone service from starting automatically after installation
 echo "manual" > /etc/init/keystone.override
 
- Run the following command to install the packages

apt-get -y install keystone apache2 libapache2-mod-wsgi memcached python-memcache

- Sao luu file cau hinh 

cp /etc/keystone/keystone.conf /etc/keystone/keystone.conf.bak


- Edit the /etc/keystone/keystone.conf file and complete the following actions

```sh 

[DEFAULT]
log_dir = /var/log/keystone

admin_token = Welcome123
public_bind_host = 10.10.10.120

```

- Populate the Identity service database

```sh
su -s /bin/sh -c "keystone-manage db_sync" keystone
```

#### Configure the Apache HTTP server
- Edit the /etc/apache2/apache2.conf file and configure the ServerName option to reference the 10.10.10.120 node:

echo "ServerName 10.10.10.120" >> /etc/apache2/apache2.conf


- Create the /etc/apache2/sites-available/wsgi-keystone.conf file with the following content

```sh
Listen 5000
Listen 35357

<VirtualHost *:5000>
    WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone group=keystone display-name=%{GROUP}

```
- Enable the Identity service virtual hosts
 ln -s /etc/apache2/sites-available/wsgi-keystone.conf /etc/apache2/sites-enabled
 
- Restart the Apache HTTP server

service apache2 restart

- Because this configuration uses an SQL database server, you can remove the SQLite database file:
rm -f /var/lib/keystone/keystone.db

- Configure the authentication token, endpoint URL, Identity API version
