Single click installation of WebLogic 14c|12c in Linux

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 situation but only few of them who have "AUTOMATION IN MINDS" could attempt to resolve this with a nicely blended Shell script.

Here I would like to target two types of installations with two different Shell 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

YOu can use the same logic in WebLogic 14c the latest version as well.
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:

• Silent Mode installation of WebLogic 12c
• WebLogic domain with WLST

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

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.
