G.3. Managing Server Instances

The server instances managed by the Red Hat Management Console are arranged in a hierarchy. At the top is the admin domain. Within the domain are hosts, representing different server machines. Each host has server groups, which identifies an inter-related group of Directory Servers using the same Admin Server instance. The individual Directory Server instances and a single Admin Server instance belong withing a server group. There can only be one Admin Server instance per server group.
These high level entries can be created and managed in the Red Hat Management Console.

G.3.1. Editing Domain, Host, Server Group, and Instance Information

The Red Hat Console displays some information about every admin domain, host, group, and server instances. Most of this information — such as the installation date and build number — are not editable, but some information is.
  1. In the Servers and Applications tab, select the entry to modify.
  2. Click Edit.
  3. Edit the instance's information. Every entry has the option to change its name and description. The host, which is the physical machine on which the instances are installed, also has the option of changing the location.
  4. Click OK.

G.3.2. Creating and Removing Admin Domains

An admin domain is a container entry for server groups (and each server group contains Directory Server instances which are configured to work with the same Configuration Directory Server and the same Admin Server, which is also in the server group).

G.3.2.1. Creating and Editing an Admin Domain

To create a new admin domain:
  1. In the top menu, click the Console menu item.
  2. Select Create New Administration Domain.
  3. Fill in the admin domain's information, including information for a new Directory Server instance.
  4. Click OK.
To edit an admin domain, select the entry in the server window and click the Edit button.

Warning

The admin domain settings affect all servers within the domain. Making any changes to the admin domain settings means that all servers in the domain must be restarted.

G.3.2.2. Removing an Admin Domain

To remove an admin domain:
  1. Highlight the admin domain to remove in the navigation tree.
  2. In the top menu, click the Console menu item.
  3. Select Remove Administration Domain.
  4. Click Yes.

Note

Any server group and servers within the domain must be removed before the domain can be deleted.

G.3.3. Creating a New Directory Server Instance

After the default Red Hat Directory Server and Admin Server instances are installed and configured, additional Directory Server instances can be created using the same schema and configuration and in the same installation directory, /etc/dirsrv. Having multiple instances on the same host makes it easier to maintain divisions between directories while simplifying administering multiple directories.
  1. In Red Hat Management Console, select the server group that will contain the new server instance.
  2. Right-click on the server group entry, and select Create Instance Of, and then Red Hat Directory Server.
    Alternatively, click Object in the top menu bar, and select Create Instance Of.
  3. Fill in the information for the new instance of Directory Server, including the base DN, Directory Manager, and port.
  4. Click OK.

G.3.4. Deleting a Directory Server Instance

  1. In the Red Hat Management Console, select the instance to delete.
  2. Right-click the server instance, and select Remove Server.
  3. Click Yes to confirm the deletion.
