Single click installation of WebLogic 12c in a Vagrant Box

Current IT Trending towards devOps automation in every Software product development. I am also part of  this devOps culture. I had a thought that, How much I can leverage my regular task by making simple shell script for Installation task.

As every Oracle WebLogic system administrator would pass through this only few of them could attempt to resolve this with automation script.

Here I would like to target two installations with two different scripts:

  1. Fusion Middleware 12.2.1.2.0 WebLogic Server installation
  2. Fusion Middleware 12.2.1.2.0 Infrastructure installation


Objective of this script is to get single hit would do multiple tasks such as:

  • JAVA installation
  • setting the JAVA_HOME in shell profile
  • using Java run the WebLogic installer in silent mode


Assumptions:

  • Downloaded Software will be stored in common shared location. 
  • Installation of software such as JDK, WebLogic will be same mount point and directory structure
  • Linux Operating System user have bash shell!   
Knowledge base:


Auto Install pre-requisite for Application - Script 
wls.cfg
JDK_INSTALLER=jdk-8u*-linux-x64.tar.gz
JDK_INSTALLER_PATH=/u01/app/software/jdk
INSTAL_LOC=/u01/app/oracle
WLS_INSTALLER=fmw_12.*_wls.jar
WLS_INSTALLER_PATH=/u01/app/software/FMW_wls
SILENT_DIR=/u01/app/software/silent

Script name: install_wls.sh
#!/bin/bash
# This script will be installing JDK
# installing WebLogic in silent mode

cd $INSTAL_LOC
tar -zxvf $JDK_INSTALLER_PATH/$JDK_INSTALLER

Oracle Fusion Middleware Infrastructure installation Shell Script

Here the script is little bit improved the installer normally coming as zip file which can be uncompressed by script and also silent file will be using
INSTALL_TYPE=Fusion Middleware Infrastructure With Examples
Now the script for Infrastructure will be look like this.
#!/bin/bash
# This script will be installing JDK
# installing WebLogic in silent mode
#
JDK_INSTALLER=jdk-8u121-linux-x64.tar.gz
JDK_INSTALLER_PATH=/u01/app/software/jdk
INSTAL_LOC=/u01/app/oracle

echo "installing JDK ${JDK_INSTALLER}"
cd $INSTAL_LOC
tar -zxvf $JDK_INSTALLER_PATH/$JDK_INSTALLER

ls -l
echo confirm JDK installation
cd $INSTAL_LOC/jdk*

JAVA_HOME=`pwd`
echo "export JAVA_HOME=$JAVA_HOME">>$HOME/.bashrc
echo "export PATH=$JAVA_HOME/bin:$PATH">>$HOME/.bashrc

. $HOME/.bashrc

echo "Check for java version"
java -version

echo Installing WebLogic now...
echo .

WLS_INSTALLER=fmw_12.2.1.2.0_infrastructure_Disk1_1of1.zip
WLS_INSTALLER_PATH=/u01/app/software/FMW_wls
cd $WLS_INSTALLER_PATH
unzip $WLS_INSTALLER_PATH/$WLS_INSTALLER

INFRA_JAR=fmw_12.2.1.2.0_infrastructure.jar

SILENT_DIR=/u01/app/software/silent

java -jar $WLS_INSTALLER_PATH/$INFRA_JAR -silent -invPtrLoc $SILENT_DIR/oraInst.loc -responseFile $SILENT_DIR/fmw12.2.1_infra_install.rsp

echo "FMW Infrastructure $WLS_INSTALLER installed successfully...."
echo .
echo setting MW_HOME ...
MW_HOME=`grep ORACLE_HOME $SILENT_DIR/$SILENT_DIR/fmw12.2.1_infra_install.rsp |cut -d'=' -f2`
echo "export MW_HOME=$MW_HOME">>$HOME/.bashrc
echo "export WL_HOME=$MW_HOME/wlserver">>$HOME/.bashrc
echo "alias wlst=$MW_HOME/oracle_common/common/bin/wlst.sh">>$HOME/.bashrc
. $HOME/.bashrc
echo "Use wlst command to test everything working..."


Note: If you are running other than Linux platform you can use ksh shell .profile.

keep in touch with your comment and suggestions for improve more effective way.

cheers!!!

Essential Middleware Administration takes in-depth look at the fundamental relationship between Middleware and Operating Environment such as Solaris or Linux, HP-UX. Scope of this blog is associated with beginner or an experienced Middleware Team members, Middleware developer, Middleware Architects, you will be able to apply any of these automation scripts which are takeaways, because they are generalized it is like ready to use. Most of the experimented scripts are implemented in production environments.
