4.3. Configuring Red Hat Gluster Storage Console

Procedure 4.5. Configuring the Console

1. Start console setup

   #rhsc-setup

   The script then checks whether it is performing an upgrade or an installation before proceeding.

   No product updates found

2. Check hostname configuration

   The rhsc-setup script automatically detects the hostname. Correct the detected hostname if required. The fully qualified domain name should have both forward and reverse lookup records in DNS.

   Host fully qualified DNS name of this server [autodetected domain-based name]:

3. Configure firewall

   The rhsc-setup script looks for firewall managers which are both active and enabled in the environment and you can choose to configure the firewall.

   Setup can automatically configure the firewall on this system.
   Note: automatic configuration of the firewall may overwrite current settings.
   Do you want Setup to configure the firewall? (Yes, No) [Yes]: yes
   [INFO] iptables will be configured as firewall manager.

4. Configure database

   You can use either a local or remote PostgreSQL database. The script can automatically configure the database, including adding a user and a database, or use the values that you provide.

   Where is the database located? (Local, Remote) [Local]: Local
   Setup can configure the local postgresql server automatically for the engine to run. This may conflict with existing applications.
   Would you like Setup to automatically configure postgresql, or prefer to perform that manually? (Automatic, Manual) [Automatic]: Automatic

   For information on how to prepare a PostgreSQL database, see Chapter 8, Use a PostgreSQL Database Server with Red Hat Gluster Storage Console

5. Configure administrator credentials

   You need to set an administrator password for the automatically created administrative user of the Red Hat Gluster Storage Console: admin@internal.

   Engine admin password:
   Confirm engine admin password:

   A message appears on the terminal if the password you have set is weak.

6. Configure certificates

   The Console uses certificates to communicate securely with its hosts. You need to provide the organization name for the certificate. This certificate can also optionally be used to secure HTTPS communications with the Console.

   Organization name for certificate [autodetected domain-based name]:

7. Configure web server

   The external SSL (HTTPS) communications with the Console are secured with the self-signed certificate created in the PKI configuration stage by default, to securely communicate with hosts. You may choose to use another certificate for external HTTPS connections, without affecting how the Console communicates with hosts.

   Setup can configure apache to use SSL using a certificate issued from the internal CA.
   Do you wish Setup to configure that, or prefer to perform that manually? (Automatic, Manual) [Automatic]: Automatic

   The Red Hat Gluster Storage Console uses the Apache web server to present a landing page to users. rhsc-setup script can make the Console's landing page the default page presented by Apache.

   Setup can configure the default page of the web server to present the application home page. This may conflict with existing applications.
   Do you wish to set the application as the default page of the web server?
   (Yes, No) [Yes]:

8. Configure console settings

   The rhsc-setup script by default uses the GlusterFS application mode and skips the NFS configuration.

   [ INFO ] NFS configuration skipped with application mode Gluster

   The rhsc-setup script validates all the inputs, and warns you of any possible problem. Further input is only required if any of the inputs you provided would adversely impact the environment.
   The rhsc-setup script prompts to confirm whether to connect to the Red Hat Access Plug-in.
   On agreeing to configure the proxy server, you are prompted to enter the IP address and the port number of the proxy server. You also have the option to set a user name for the proxy server with a password.

   Would you like transactions from the Red Hat Access Plug-in sent from the Red Hat Gluster Storage Console to be brokered through a proxy server? (Yes, No) [No]: No

   The rhsc-setup script prompts to confirm whether to enable or disable monitoring by entering Yes or No
   For information on how to configure Nagios, see Configuring Nagios for Red Hat Gluster Storage Console in Red Hat Gluster Storage Console 3.4 Administration Guide

   Would you like external monitoring to be enabled? (Yes, No) [Yes]:
