After you install software on a single server, or after
you install the master server for a distributed server installation,
you can install additional servers to support crawling, indexing,
and search processing.
You must ensure that all software that is needed to support
the intended server role is installed before you run the IBM® Content
Analytics with Enterprise Search installation program. For
example, if you add a search server and want to use WebSphere® Application
Server to support your search
applications, you must ensure that a supported version of WebSphere Application
Server is installed before you
add the server. You cannot use WebSphere Application
Server and
the embedded web application server on the same system.
When you add servers, you install the software and specify
paths and ports for your system environment. Later, you use the administration
console to assign the role of the server. The types of servers that
you can add depend on the supported system configurations.
- Single server installations
- You can add more than one search server and document processing
server. On AIX® or Windows platforms, you can also add one high
availability server to provide backup and failover support for crawling,
indexing, and search.
- Distributed server installations
- You must add a crawler server and at least one search server.
You can then add additional search servers and document processing
servers. On AIX or Windows platforms, you can also add one high
availability server to provide backup and failover support for crawling
and one high availability server to provide backup and failover support
for indexing.
If you add high availability servers, the high
availability server and the master server must share the same data
directory (ES_NODE_ROOT). The high availability servers are supported
through IBM PowerHA® for AIX and Microsoft Cluster Service
(MSCS) on Windows. Before
you add a high availability server, you must first install and configure IBM PowerHA for AIX or Microsoft Cluster Service on the high availability
server and the corresponding master server with the same configuration
settings. If you add multiple high availability servers in a distributed
server installation on Windows,
you must create a separate cluster for each high availability server.
Before you install IBM Content
Analytics with Enterprise Search on
a backup server, prepare any required resources such as the storage
device on which you installed the IBM Content
Analytics with Enterprise Search data directory. Ensure
that the required resources are online to the server on which you
plan to install the product.
Restriction: You cannot
add high availability servers if you install IBM Content
Analytics with Enterprise Search as a non-root user.
To
add servers by using the graphical installation program:
- From the product DVD or electronic
distribution image, extract the files in the .zip file or .tar file
for your operating system and run the appropriate command:
Option |
Description |
AIX or Linux |
- Enter: ./launchpad.sh
- To view information about prerequisites or any known issues before
you install the product, click Prerequisite Information or Release
Information.
- Click Install Product to start the installation
program.
|
Windows |
- Double-click the launchpad.exe file or enter launchpad.exe in
a command window.
- To view information about prerequisites or any known issues before
you install the product, click Prerequisite Information or Release
Information.
- Click Install Product to start the installation
program.
|
- Follow the instructions in the installation wizard. When you specify installation options:
- Verify the fully qualified host
name of this computer.
Restriction: You
cannot specify an IPv6 address as the host name of the server.
- Accept or change the user name and password for the
default IBM Content
Analytics with Enterprise Search administrator.
The administrator ID and password must be the same on all servers.
To administer the IBM Content
Analytics with Enterprise Search system, you log in as the
master administrator with this user name and password. The default
value is esadmin. If you log in with a non-root
user ID to start the installation program, you cannot change the user
name and you cannot select the check box to create the user. To specify
a domain user, use the format username@domain
name. The domain user cannot be created by the
installation program.
If you plan to use WebSphere Application
Server instead of the embedded
web application server, specify the user name for an administrative
user who is registered in the LDAP server registry. Authentication
for all administrative and application users that you add to the system
is handled through WebSphere Application
Server global
security.
- For the server type, select Additional server.
- Click Install to use the default
settings for all other installation options and start installing the
software.
- Optional: If you want to change the default
settings, click Advanced Options instead of
clicking Install.
Requirement: In the following cases, you must
click
Advanced Options to change the default
settings:
- If you add a high availability server, you must specify the path
to the data directory that is shared by the master server and the
high availability server. You can ignore the warning message that
the installation program will overwrite the data directory.
- If you add a search server and plan to use WebSphere Application
Server instead of the the embedded
web application server, you must click Advanced Options to
specify information about your WebSphere Application
Server installation.
- Use the following guidelines when you specify installation
options:
- On AIX or Linux, if you do not accept the
default paths for the installation and data directories, ensure that
the paths that you specify do not contain spaces in the path names.
- Ensure that the installation directory for each additional server
is a separate, non-shared directory.
- Ensure that the default ports do not conflict with
any ports that are already assigned to other applications on this
computer.
- If you select the option to use WebSphere Application
Server and global security is
enabled, you must specify the WebSphere Application
Server administrative
user name and password.
- On the summary page, review the options that
you selected and click Install to start installing
the software.
- On Windows, restart the server.
- Log in as the IBM Content
Analytics with Enterprise Search administrative user and
use one of the following methods to start the common communication
layer (CCL) service:
- On AIX or Linux, enter startccl.sh -bg.
- At a Windows command prompt, enter startccl.
- Use the Windows Services administrative tool to start the
CCL in the background:
- Start Windows Services: .
- Right-click IBM Content
Analytics with Enterprise Search and
click Start.
- Verify that the CCL port is on listen mode (for
example, use the netstat -na command). Also verify
that the host name is updated on the domain name server (DNS) and
that it can be pinged from the master server.
After you install the software on an additional server,
open the administration console on the master server and assign an
appropriate role for the additional server. If you installed a high
availability server, you must first configure the server before you
assign the role.
