Install openstack keystone on fedora 40

 To install OpenStack Keystone on Fedora 40, follow these steps:

1. Update Your System

Ensure your system is up-to-date:

```bash sudo dnf update -y

**2. Install Required Dependencies**

Install Python 3 and essential OpenStack client packages:

```bash
sudo dnf install -y python3 python3-pip python3-openstackclient
```

**3. Install Keystone**

Install the Keystone package:

```bash
sudo dnf install -y openstack-keystone
```

**4. Configure the Database**

Keystone requires a database to store information. For this guide, we'll use MariaDB.

- **Install MariaDB:**

```bash
sudo dnf install -y mariadb-server
sudo systemctl enable mariadb
sudo systemctl start mariadb
```

- **Secure the Database Installation:**

```bash
sudo mysql_secure_installation
```

Follow the prompts to set the root password and secure the installation.

- **Create the Keystone Database and User:**

```bash
sudo mysql -u root -p
```

In the MariaDB shell, execute:

```sql
CREATE DATABASE keystone;
GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY 'your_keystone_password';
FLUSH PRIVILEGES;
EXIT;
```

**5. Configure Keystone**

- **Edit the Keystone Configuration File:**

```bash
sudo nano /etc/keystone/keystone.conf
```

In the `[database]` section, set the connection string:

```ini
[database]
connection = mysql+pymysql://keystone:your_keystone_password@localhost/keystone
```

In the `[token]` section, configure the provider:

```ini
[token]
provider = fernet
```

**6. Populate the Keystone Database**

Synchronize the database:

```bash
sudo keystone-manage db_sync
```

**7. Initialize Fernet Keys**

Generate Fernet keys for token encryption:

```bash
sudo keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
sudo keystone-manage credential_setup --keystone-user keystone --keystone-group keystone
```

**8. Bootstrap Keystone**

Initialize Keystone with an administrative account:

```bash
sudo keystone-manage bootstrap --bootstrap-password admin_password \
  --bootstrap-admin-url http://localhost:5000/v3/ \
  --bootstrap-internal-url http://localhost:5000/v3/ \
  --bootstrap-public-url http://localhost:5000/v3/ \
  --bootstrap-region-id RegionOne
```

**9. Configure Apache HTTP Server**

Keystone uses Apache as its web server.

- **Install Apache:**

```bash
sudo dnf install -y httpd mod_wsgi
```

- **Configure Apache for Keystone:**

```bash
sudo ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/
```

- **Start and Enable Apache:**

```bash
sudo systemctl enable httpd
sudo systemctl start httpd
```

**10. Finalize the Installation**

- **Set Up Administrative Environment Variables:**

```bash
export OS_USERNAME=admin
export OS_PASSWORD=admin_password
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://localhost:5000/v3
export OS_IDENTITY_API_VERSION=3
```

- **Verify the Installation:**

```bash
openstack token issue
```

If successful, this command will display a token, indicating that Keystone is properly installed and configured.
