Watson Explorer Content Analytics installation – Steps

I installed Watson Explorer Content Analytics several times in the last months, then, I created a simple Step by step that can be useful to who is starting to work with this. I’m sharing here, please, fell free to add any comment and help me to improve this how-to. Hope that can be useful to you if you are here :D.

Pre-Installation Checklist / Pre-requisites

The following steps should be performed to prepare the server for software installation. This step by step cover the installation in a Red Hat 7 machine. The following 32-bit libraries are required on Linux x86-64 systems:

• libstdc++33 (compat-libstdc++-33.i686 / libstdc++33-32bit)
• libstdc++ (libstdc++.i686 / libstdc++6-32bit)
• zlib (zlib.i686 / libz1-32bit / zlib-32bit)
• libXext (libXext.i686 / libXext6-32bit / xorg-x11-libXext-32bit)
• libXft (libXft.i686 / libXft2-32bit / xorg-x11-libs-32bit)
• libXi (libXi.i686 / libXi6-32bit / xorg-x11-libs-32bit)
• libXp (libXp.i686 / libXp6-32bit / xorg-x11-libXp-32bit)
• libXtst (libXtst.i686 / libXtst6-32bit / xorg-x11-libs-32bit)
• libXm (if thumbnails are needed)
• libXt (if thumbnails are needed)
• java-1.8.0-ibm-1.8.0.2.10-1jpp.7.el6.x86_64
• Httpd

The commands to install the libraries are:

1. yum install -y libstdc++.i686 libXext.i686 libXft.i686 libXi.i686 libXp.i686 libXtst.i686 libXt.i68
2. yum install -y zlib.i686 httpd
3. yum -y install apr apr-util boost-filesystem boost-iostreams boost-program-options boost-regex boost-serialization

• If SELinux is enabled, then it will need to be disabled during installation of WEX
  

• Ensure that the disk space has been allocated to the WEX installation path

• The default path is /opt/ibm/dataexplorer

• Ensure that the disk space for /tmp partition have sufficient space for the installation, at least 10 gb

If not assign the tmp to a directory that has extra space with the commands:

1. mkdir /opt/IBM/dataexplorer/tmp
2. export IATEMPDIR=/opt/IBM/dataexplorer/tmp

• Install a web server to run the Foundational Components -> On Linux install the latest version of Apache (not required for AC)

• Ensure that the LINUX subscription libraries are available for the yum command

• DB2 connect client configured

• Install Java – java-1.8.0-ibm-1.8.0.2.10-1jpp.7.el6.x86_64 (you can get the package from oracle also, make sure to add Java to the server path)
  

Users and Folders creation for WEX AE (must be perform with root level access)

1. Add installation account (esadmin) for server install.
   1. useradd esadmin
   2. create a password for the esadmin user (usually esadmin12)

3. Create Watson Directories
   1. mkdir -p /watson/archives

4. Copy the installation tarball onto the server into.

5. Untar the tarball that contains installation files.mkdir /opt/IBM/dataexplorer/WATSON_EXPR_ADV_EAC_V11.0.2_LNX_M
   cd /opt/IBM/dataexplorer /WATSON_EXPR_ADV_EAC_V11.0.2_LNX_M
   tar -xvf ./watson/archives/WATSON_EXPR_ADV_EAC_V11.0.2_LNX_M.tar

WEX AE Installation Details:

1. (Note must be performed with root level access) Install the software. (Note: Responses for Master node when selecting server type)

1. 1. cd /opt/IBM/dataexplorer/WATSON_EXPR_ADV_EAC_V11.0.2_LNX_M/
   2. ./install.bin -i console

• Installation Responses: (Also see installation screenshots below)
  • Choose Locate : English
  • PRESS TO CONTINUE:
  • Press Enter to continue view license agreement or 1 to accept: 1 (accept)
  • Enter fully qualified hostname of this server: (Hostname will be detected, hit enter. see example below)

• • Administrator user name: (Default: esadmin): (Hit enter to take default)

• • Create user account Enter the Number for your choice..: 2 ( the administrator user account ‘esadmin’ already exists)

• • Enter Administrator Account password: your_esadmin_password that you created for the user earlier (esadmin12)

• • Select a Server Type: (Response depends on type of server being installed on)
    • (1 –Master all on one server )

If installation is consists of a single server.

• • • (2 -Master Distributed Server )

If installation consists of multiple servers, and the current server is the Master server

• • • (3 -Additional Server )

If the installation is for a server (ie.. Search Server) that will connect to a Master

Select: 1

• • Do you want to install advanced options: 1 (YES)
  • Enter absolute path of the data directory ES_NODE_ROOT (default: /opt/IBM/dataexplorer/esdata ) /opt/IBM/dataexplorer/esdata
  • Enter the absolute path to install : /opt/IBM/dataexplorer/es

• • Common Communication Layer Port (default: 6002) Hit enter for the default

• • Search Server ESSearchServer Port (default: 8394) Hit enter for the default

• • Web Application Server (default embedded) 1 –embedded

• • THE INSTALLATION WILL BEGIN AND RUN ABOUT 5-10 MINUTES
    

…

• • This completes the WAC (Watson Content Analytic) installation
  • You can start esadmin to test:
