Adding additional Application Servers

To meet the demands of a larger data center, you can deploy additional Application Servers. The additional Application Server is used for improving the performance of TrueSight Server Automation. The method described here for adding additional Application Servers is relevant only if you installed your default Application Server node using the unified product installer. When you install additional Application Servers, this process installs an Application Server and RSCD agent on the target server.

This topic includes the following sections:

• Set up a PsExec Server
• Add an additional Application Server

Before you begin

• (Windows only) To add an additional application server on a Windows system, you must first set up a PsExec server on a Windows server. A PsExec server functions as a proxy to execute psexec requests on a Windows Application Server without an agent. 
  To set up the PsExec Server:

  The [expand] macro is a standalone macro and it cannot be used inline. Click on this message for details.
  This macro generates standalone content. As a consequence you need to make sure to use a syntax that separates your macro from the content before and after it so that it's on a line by itself. For example in XWiki Syntax 2.0+ this means having 2 newline characters (a.k.a line breaks) separating your macro from the content before and after it.
  

• (Windows only) Ensure that you must have Server Message Block (SMB) v2 enabled on a Windows server.

• (Linux) Ensure that the umask setting is 0022 on the host where you want to install the additional Application Server.

  Restrictive umask setting is not supported. For example, umask setting 077 in /etc/profile and /etc/bashrc

Adding an additional Application Server

Use the following steps to add an additional Application Server to your environment.

1. On the file server, locate or create the directory structure under the root for installer_bundle/<os>/files, where <os> is either linux or windows, for example, C:\Program Files\BMC Software\BladeLogic\storage\installer_bundle\windows\files. 
2. Copy the contents of <upi_dir>/Disk1/files/installers into the <fileServer>/installer_bundle/<os>/files directory.
3. Start the TrueSight Server Automation Console.
4. Click Add TSA Application Server Machine under the Configuration menu in the Console. When you add the Application Servers, the Compliance Content is not synchronized. This is by design as the objective is to create another Application Server with basic configuration. You must perform additional customizations. For information about additional folders to synchronize, see Configuring-multiple-Application-Servers-on-different-hosts.
5. Select the Node Details and Advance Options tabs and enter the following node details and advanced options:
   • Node Details
   • Advanced Options
6. Click Add Node. 
7. Review the validation details. 

Node Details

• Host Name — Host name or IPv4 address of the Application Server. Note that if your Application Server is on an IPv6 address system you can only enter the host name of the server.

• Execution Protocol — Specifies the mechanism for accessing the agentless Application Server machine that you are setting up. Select one of the following: 

- (Linux only) SSH Execution Protocol — Executes commands directly on the agentless host using the credentials defined on this panel. 

- (Linux only) SSH + SUDO Execution Protocol — Executes commands directly on the agentless host using the credentials defined on this panel. The sudo command is attached as a prefix to all commands. If sudo requests a password, the passphrase entered on this panel is used.

- (Linux only) SSH + SU Execution Protocol — Executes commands directly on the agentless host using the credentials defined on this panel. The credentials defined on this panel are used to issue the su command to gain elevated privileges.

- (Windows only) PSEXEC_Execution Protocol — Executes psexec requests on an agentless Windows host. This protocol is required when installing agents on Windows servers. Authentication on agentless hosts uses credentials defined in an automation principal that you specify on this panel.  

• Administrator ID — User name of an account with Administrator or Superuser privileges on the additional Application Server machine.

  Note

  If you are using a domain user, enter the ID in the <DominName>\<UserID> format. For example, bmc.com\TestID.

• Passphrase — Password of the account with Administrator or Superuser privileges on the additional Application Server machine.
• Confirm — Confirm password of the account with Administrator or Superuser privileges on the additional Application Server machine.
• Node OS Type — Operating system running on the additional Application Server machine. For example WINDOWS_64 or LINUX_64.
• PsExec Server — (Windows only) Host name or IPv4 address of the PsExec server is installed. Note that if your PsExec server is on an IPv6 address system you can only enter the host name of the server.

Advanced Options

• Install Path — Path on which you want to install the additional Application Server. For example, /opt/bmc/bladelogic on Linux or C:\Program Files\BMC Software\BladeLogic\ on Windows.
• Base port — Application Server ports are normally configured from a base port, with 9800 being the default base port. Arbitrary port assignments can be made in all cases. For more information, see Application Server ports.

• Temporary staging directory - (Linux only) During installation, the system stores temporary files in the /tmp directory. You can specify an alternate location to store the temporary files, if you do not have enough space or you do not have access to the /tmp directory. 

Validation

The status of the installation process is displayed.

Where to go from here

Harden the security configurations on each of the new application server nodes. Copy the following files from the default Application Server node to each of the newly added secondary nodes:

• secure
• user
• users.local
• export
