This post describes the installation of the WebLogic Server Version 12.2.1.3 on Linux Version 6 and 7.
The following tasks are performed and described:
- Preparing the Operating System for the installation of the WebLogic Server 12.2.1.3
- Installation JDK 1.8 and the WebLogic Server 12.2.1.3
Step 1# Download the Weblogic Server 12c software from Oracle Technology Network.
Step 2# The following actions should be performed by the "root" user.
Create a new group and user (you can create your own custom user & group)
#groupadd -g 501 oinstall
#useradd -u 501 -g oinstall oracle
#passwd oracle
Step 3# Create the directories in which the Oracle software will be installed.
#mkdir -p /u01/app/oracle/Middleware/Oracle_Home
#chown -R oracle:oinstall /u01
#chmod -R 775 /u01
Oracle WebLogic Server Directory Structure
Step 4# Append the following entries into the "/home/oracle/.bash_profile" file.
# Adjust paths as your requirement.
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/Middleware/Oracle_Home
export MW_HOME=$ORACLE_HOME export WLS_HOME=$MW_HOME/wlserver
export JAVA_HOME=/u01/app/oracle/jdk1.8.0_151 export PATH=$JAVA_HOME/bin:$PATH
Step 5# Make sure the "/etc/hosts" file contains correct entries for both the "localhost" and real host names.
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
xx.xx.xx.xx myweblogic12c.localdomain myweblogic12c
e.g. -
192.168.1.1 myweblogic12c.localdomain myweblogic12c
Step 6# Set the OS Limits (as root) for open files and open process.
#Add following rows to the file /etc/security/limits.conf:
* soft nofile 4096
* hard nofile 65536
* soft nproc 2047
* hard nproc 16384
#Add following rows to the file /etc/security/limits.d/90-nproc.conf:
# From
* soft nproc 1024
#To
* - nproc 16384
Step 7# Install the JDK.
# su -l oracle
$ cd $ORACLE_BASE
$ cp /home/oracle/Downloads/jdk-8u151-linux-x64.tar.gz .
$ tar -xzvf jdk-8u151-linux-x64.tar.gz
$ source /home/oracle/.bash_profile
Step 8# Installation
Run the installer as the "oracle" user.
Go to the downloads directory (here we assuming weblogic12c downloaded on Downloads directory).
$ cd ~/Downloads
$ java -jar fmw_12.2.1.3 .0_wls.jar
If this is is the first installation on the machine you will need to specify an inventory location. Enter the inventory location, like "/u01/app/oraInventory" and click the "OK" button.
Enter the middleware home ("/u01/app/oracle/product/12.2.1") and click the "Next" button.
Wait for the prerequisite checks to complete. If there are failures, correct them and rerun the checks. If there are no failures, click the "Next" button.
Create Domain
Launch the Configuration Wizard with the following command.
$ $ORACLE_HOME/oracle_common/common/bin/config.sh
Accept the "Create a new domain" option, enter the domain name at the end of the "Domain Location", then click the "Next" button. In this case my domain was called "mydomain", so the path I used was "/u01/app/oracle/config/domains/mydomain".
Select the required product template and click the "Next" button.
Enter the administrator credentials and click the "Next" button.
Enter the domain mode and JDK details, then click the "Next" button.
Select any required advanced configuration options. For this example I ignored the advanced configuration. Click the "Next" button.
If you are happy with the configuration summary screen, click the "Create" button.
Once the domain is created, click the "Next" button.
Make a note of the Admin Server URL and click the "Finish" button.
Post-Installation
If you chose the "Production Mode" options for the domain, you will need to create a "boot.properties" file for the scripts referred to later to work without credentials. Adjust the DOMAIN_HOME and credentials appropriately.
$ export DOMAIN_HOME=$ORACLE_BASE/config/domains/mydomain $ mkdir -p $DOMAIN_HOME/servers/AdminServer/security $ echo "username=weblogic" > $DOMAIN_HOME/servers/AdminServer/security/boot.properties
$ echo "password=Password1" >> $DOMAIN_HOME/servers/AdminServer/security/boot.properties
The "$ORACLE_BASE/config/domains/mydomain" directory now contains a script that can be used to start the server. Remember to use the "&" if you want access to the commandline to be returned.
$ $DOMAIN_HOME/startWebLogic.sh &
Once the server is started you can access the administrator console using the "http://hostname:port/console" URL. Log in using the username and password provided in the previous step.
