Installing on Amazon Elastic Compute Cloud (Amazon EC2)

Installing ManageIQ

Installing ManageIQ consists of the following steps:

Downloading the appliance for your environment as a virtual machine snapshot template.
Setting up a virtual machine based on the appliance.
Configuring the ManageIQ appliance.

After you have completed all the procedures in this guide, you will have a working environment on which additional customizations and configurations can be performed.

Obtaining the appliance

Requirements

Below are the two sets of requirements for installing ManageIQ on Amazon EC2.

ManageIQ Requirements

44 GB of space on the chosen datastore.
12 GB RAM.
4 vCPUs.

Amazon EC2 Requirements

An Amazon S3 bucket to store the disk image that will be imported to AWS as a snapshot.
A VM import service role (IAM role) named vmimport.

For information on creating an Amazon S3 bucket and a VM Import Service Role, see the Amazon EC2 documentation.

Uploading the Appliance to an Amazon S3 Bucket

From your local file system, you can now upload the ManageIQ appliance VHD image obtained in Obtaining the appliance to the Amazon S3 bucket, using your choice of tool, such as AWS client or directly upload the Appliance image from your S3 bucket on AWS Management Console.

Configuring Amazon EC2 to Import the Appliance

Important:

These are the procedural steps as of the time of writing. For the latest information on importing a virtual machine as an image, see the Amazon EC2 documentation.

Install the AWS client on the computer you want to interact with the AWS API from.
```
 $ pip install awscli
```
Configure and download your AWS secret/access key by following the steps in the Managing Access Keys for Your AWS Account documentation.

Configure the AWS client with your access/secret key. For example:

 $ aws configure
 AWS Access Key ID [******]: ACCESS_KEY
 AWS Secret Access Key [******]: SECRET_KEY
 Default region name [None]:
 Default output format [None]:

Create the trust-policy.json file for the vmimport role. For example:

 {
    "Version": "2012-10-17",
    "Statement": [
       {
          "Effect": "Allow",
          "Principal": { "Service": "vmie.amazonaws.com" },
          "Action": "sts:AssumeRole",
          "Condition": {
             "StringEquals":{
                "sts:Externalid": "vmimport"
             }
          }
       }
    ]
 }

Create the vmimport role using the trust-policy.json file that you just created.
```
 $ aws iam create-role --role-name vmimport --assume-role-policy-document file://trust-policy.json
```
Note:

This user must have permissions to create and modify IAM roles.

Create the role-policy.json file. Be sure to use the exact S3 bucket name. For example:

 {
   "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListAllMyBuckets"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:CreateBucket",
        "s3:DeleteBucket",
        "s3:DeleteObject",
        "s3:GetBucketLocation",
        "s3:GetObject",
        "s3:ListBucket",
        "s3:PutObject"
      ],
      "Resource": ["arn:aws:s3:::BUCKET_TO_UPLOAD_IMAGE","arn:aws:s3:::BUCKET_TO_UPLOAD_IMAGE/*"]
    },
    {
      "Effect": "Allow",
      "Action": [
        "iam:CreateRole",
        "iam:PutRolePolicy"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "ec2:CancelConversionTask",
        "ec2:CancelExportTask",
        "ec2:CreateImage",
        "ec2:CreateInstanceExportTask",
        "ec2:CreateTags",
        "ec2:DeleteTags",
        "ec2:DescribeConversionTasks",
        "ec2:DescribeExportTasks",
        "ec2:DescribeExportImageTasks",
        "ec2:DescribeInstanceAttribute",
        "ec2:DescribeInstanceStatus",
        "ec2:DescribeInstances",
        "ec2:DescribeTags",
        "ec2:ExportImage",
        "ec2:ImportInstance",
        "ec2:ImportVolume",
        "ec2:StartInstances",
        "ec2:StopInstances",
        "ec2:TerminateInstances",
        "ec2:ImportImage",
        "ec2:ImportSnapshot",
        "ec2:DescribeImportImageTasks",
        "ec2:DescribeImportSnapshotTasks",
        "ec2:CancelImportTask"
      ],
      "Resource": "*"
    }
  ]
 }

Apply the vmimport role to the ManageIQ appliance image you uploaded to the S3 bucket.

 $ aws iam put-role-policy --role-name vmimport --policy-name vmimport --policy-document file://role-policy.json

Importing the Appliance to Amazon Elastic Compute Cloud (Amazon EC2)

To import the appliance:

Create a containers.json file:

 {
     "Description": "NAME OF IMPORTED SNAPSHOT IN AWS",
     "Format": "vhd",
     "UserBucket": {
         "S3Bucket": "BUCKET WITH UPLOADED .VHD IMAGE",
         "S3Key": "PATH OF .VHD IMAGE"
     }
 }

See the AWS documentation on VM import and export requirements, such as image formats, instances, volume and file system types, and using regions.

Use the AWS-CLI tools to import a disk as a snapshot. See the AWS documentation on using VM Import/Export to import a disk as a snapshot.

Note:

You can either specify a region, or if not, ensure that the S3 bucket is in the same region where you want to import the snapshot.
```
 $ aws ec2 import-snapshot --disk-container file://containers.json
```

Check the progress of your snapshot import by running the following command:

 $ aws ec2 describe-import-snapshot-tasks --import-task-ids SNAPSHOT_ID_GOT_FROM_RESPONSE

Create an AMI from the snapshot. See the AWS documentation on using options with the following command to create and register a Linux AMI from a snapshot.
```
 $ aws ec2 register-image
```

Configuring ManageIQ

After installing ManageIQ and running it for the first time, you must perform some basic configuration. To configure ManageIQ, you must at a minimum:

Add a disk to the infrastructure hosting your appliance.
Configure the database.

Configure the ManageIQ appliance using the internal appliance console.

Accessing the Appliance Console

Start the appliance and open a terminal console.
Enter the appliance_console command. The ManageIQ appliance summary screen displays.
Press Enter to manually configure settings.
Press the number for the item you want to change, and press Enter. The options for your selection are displayed.
Follow the prompts to make the changes.
Press Enter to accept a setting where applicable.

Note:

The ManageIQ appliance console automatically logs out after five minutes of inactivity.

Configuring a Database

ManageIQ uses a database to store information about the environment. Before using ManageIQ, configure the database options for it; ManageIQ provides the following two options for database configuration:

Install an internal PostgreSQL database to the appliance
Configure the appliance to use an external PostgreSQL database

Configuring an Internal Database

Before installing an internal database, add a disk to the infrastructure hosting your appliance. See the documentation specific to your infrastructure for instructions for adding a disk. As a storage disk usually cannot be added while a virtual machine is running, Red Hat recommends adding the disk before starting the appliance. ManageIQ only supports installing of an internal VMDB on blank disks; installation will fail if the disks are not blank.

Start the appliance and open a terminal console.
Enter the appliance_console command. The ManageIQ appliance summary screen displays.
Press Enter to manually configure settings.
Select Configure Application from the menu.
You are prompted to create or fetch an encryption key.
- If this is the first ManageIQ appliance, choose Create key.
- If this is not the first ManageIQ appliance, choose Fetch key from remote machine to fetch the key from the first appliance. For worker and multi-region setups, use this option to copy key from another appliance.
  
  Note:
  
  All ManageIQ appliances in a multi-region deployment must use the same key.
Choose Create Internal Database for the database location.
Choose a disk for the database. This can be either a disk you attached previously, or a partition on the current disk.

Red Hat recommends using a separate disk for the database.

If there is an unpartitioned disk attached to the virtual machine, the dialog will show options similar to the following:
```
1) /dev/vdb: 20480
2) Don't partition the disk
```
- Enter 1 to choose /dev/vdb for the database location. This option creates a logical volume using this device and mounts the volume to the appliance in a location appropriate for storing the database. The default location is /var/lib/pgsql, which can be found in the environment variable $APPLIANCE_PG_MOUNT_POINT.
- Enter 2 to continue without partitioning the disk. A second prompt will confirm this choice. Selecting this option results in using the root filesystem for the data directory (not advised in most cases).
Enter Y or N for Should this appliance run as a standalone database server?
- Select Y to configure the appliance as a database-only appliance. As a result, the appliance is configured as a basic PostgreSQL server, without a user interface.
- Select N to configure the appliance with the full administrative user interface.
When prompted, enter a unique number to create a new region.

Creating a new region destroys any existing data on the chosen database.
Create and confirm a password for the database.

ManageIQ then configures the internal database. This takes a few minutes. After the database is created and initialized, you can log in to ManageIQ.

Configuring an External Database

Based on your setup, you will choose to configure the appliance to use an external PostgreSQL database. For example, we can only have one database in a single region. However, a region can be segmented into multiple zones, such as database zone, user interface zone, and reporting zone, where each zone provides a specific function. The appliances in these zones must be configured to use an external database.

The postgresql.conf file used with ManageIQ databases requires specific settings for correct operation. For example, it must correctly reclaim table space, control session timeouts, and format the PostgreSQL server log for improved system support. Due to these requirements, Red Hat recommends that external ManageIQ databases use a postgresql.conf file based on the standard file used by the ManageIQ appliance.

Ensure you configure the settings in the postgresql.conf to suit your system. For example, customize the shared_buffers setting according to the amount of real storage available in the external system hosting the PostgreSQL instance. In addition, depending on the aggregate number of appliances expected to connect to the PostgreSQL instance, it may be necessary to alter the max_connections setting.

Note:

ManageIQ requires PostgreSQL version 9.5.
Because the postgresql.conf file controls the operation of all databases managed by a single instance of PostgreSQL, do not mix ManageIQ databases with other types of databases in a single PostgreSQL instance.

Start the appliance and open a terminal console.
Enter the appliance_console command. The ManageIQ appliance summary screen displays.
Press Enter to manually configure settings.
Select Configure Application from the menu.
You are prompted to create or fetch a security key.
- If this is the first ManageIQ appliance, choose Create key.
- If this is not the first ManageIQ appliance, choose Fetch key from remote machine to fetch the key from the first appliance.
  
  Note:
  
  All ManageIQ appliances in a multi-region deployment must use the same key.
Choose Create Region in External Database for the database location.
Enter the database hostname or IP address when prompted.
Enter the database name or leave blank for the default (vmdb_production).
Enter the database username or leave blank for the default (root).
Enter the chosen database user’s password.
Confirm the configuration if prompted.

ManageIQ will then configure the external database.

Configuring a Worker Appliance

You can use multiple appliances to facilitate horizontal scaling, as well as for dividing up work by roles. Accordingly, configure an appliance to handle work for one or many roles, with workers within the appliance carrying out the duties for which they are configured. You can configure a worker appliance through the terminal. The following steps demonstrate how to join a worker appliance to an appliance that already has a region configured with a database.

Start the appliance and open a terminal console.
Enter the appliance_console command. The ManageIQ appliance summary screen displays.
Press Enter to manually configure settings.
Select Configure Application from the menu.
You are prompted to create or fetch a security key. Since this is not the first ManageIQ appliance, choose 2) Fetch key from remote machine. For worker and multi-region setups, use this option to copy the security key from another appliance.

Note:

All ManageIQ appliances in a multi-region deployment must use the same key.
Choose Join Region in External Database for the database location.
Enter the database hostname or IP address when prompted.
Enter the port number or leave blank for the default (5432).
Enter the database name or leave blank for the default (vmdb_production).
Enter the database username or leave blank for the default (root).
Enter the chosen database user’s password.
Confirm the configuration if prompted.

Once ManageIQ is installed, you can log in and perform administration tasks.

Browse to the URL for the login screen. (https://xx.xx.xx.xx on the virtual machine instance)
Enter the default credentials (Username: admin | Password: smartvm) for the initial login.
Click Login.

Appendix

Appliance Console Command-Line Interface (CLI)

Currently, the appliance_console_cli feature is a subset of the full functionality of the appliance_console itself, and covers functions most likely to be scripted by using the command-line interface (CLI).

After starting the ManageIQ appliance, log in with a user name of root and the default password of smartvm. This displays the Bash prompt for the root user.
Enter the appliance_console_cli or appliance_console_cli --help command to see a list of options available with the command, or simply enter appliance_console_cli --option <argument> directly to use a specific option.

Example Usage.

$ ssh root@appliance.test.company.com

To create a new database locally on the server by using /dev/sdb:

# appliance_console_cli --internal --dbdisk /dev/sdb --region 0 --password smartvm

To copy the v2_key from a host some.example.com to local machine:

# appliance_console_cli --fetch-key some.example.com --sshlogin root --sshpassword smartvm

You could combine the two to join a region where db.example.com is the appliance hosting the database:

# appliance_console_cli --fetch-key db.example.com --sshlogin root --sshpassword smartvm --hostname db.example.com --password mydatabasepassword

To configure external authentication:

# appliance_console_cli --host appliance.test.company.com
