DevOps and Middleware Engineering: Weblogic 14c Horizontal Cluster Setup on Linux

Weblogic Domain Structure that we are going to setup as part of this Lab as shown below:

Step 1) Install weblogic & Configure the domain on machine1

Installation guide: http://middlewareadmin-pavan.blogspot.com/2021/01/weblogic-14c-installation-lab.html

Step 2) Create a domain with 2 managed servers on machine1:

http://middlewareadmin-pavan.blogspot.com/2021/01/weblogic-14c-domain-creation-gui-mode.html

Step 3) Install weblogic on machine2 and do not create domain.

Step 4) Shutdown ManagedServer_1, ManagedServer_2 & NodeManager on machine1

cd /home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/bin

[osboxes@machine1 bin]$ ./stopManagedWebLogic.sh ManagedServer_1

[osboxes@machine1 bin]$ ./stopManagedWebLogic.sh ManagedServer_2

[osboxes@machine1 bin]$ ./stopWebLogic.sh

[osboxes@machine1 bin]$ ./stopNodeManager.sh

Step 5) Create template using existing domain on machine1

cd /home/osboxes/Oracle/Middleware/Oracle_Home/oracle_common/common/bin

[osboxes@machine1 bin]$ ./pack.sh -domain=/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain -template=/home/osboxes/mydomain.jar -template_name="My WebLogic Domain" -template_author="pavan" -managed=true

<< read domain from "/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain"

>> succeed: read domain from "/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain"

<< set config option Managed to "true"

>> succeed: set config option Managed to "true"

<< write template to "/home/osboxes/mydomain.jar"

..............................

>> succeed: write template to "/home/osboxes/mydomain.jar"

<< close template

>> succeed: close template

[osboxes@machine1 bin]$

Step 6) Copy the template to machine2

[osboxes@machine1 bin]$ scp -r "/home/osboxes/mydomain.jar" machine2:/home/osboxes/

osboxes@machine2's password:

mydomain.jar 100% 76KB 1.7MB/s 00:00

[osboxes@machine1 bin]$

Step 7) On machine 2 : Unpack the domain using the template mydomain.jar

cd /home/osboxes/Oracle/Middleware/Oracle_Home/oracle_common/common/bin

[osboxes@machine2 bin]$ pwd

/home/osboxes/Oracle/Middleware/Oracle_Home/oracle_common/common/bin

[osboxes@machine2 bin]$ ./unpack.sh -template=/home/osboxes/mydomain.jar -domain=/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain

<< read template from "/home/osboxes/mydomain.jar"

>> succeed: read template from "/home/osboxes/mydomain.jar"

<< set config option DomainName to "base_domain"

>> succeed: set config option DomainName to "base_domain"

>> validateConfig "KeyStorePasswords"

>> succeed: validateConfig "KeyStorePasswords"

<< write Domain to "/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain"

..................................................

>> succeed: write Domain to "/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain"

<< close template

>> succeed: close template

[osboxes@machine2 bin]$

Step 8) On machine2: Verify if the domain is created

/home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain

[osboxes@machine2 base_domain]$ ls -rlt

total 20

-rw-r-----. 1 osboxes osboxes 327 Jan 20 13:14 fileRealm.properties

drwxr-x---. 2 osboxes osboxes 24 Jan 20 18:03 lib

drwxr-x---. 6 osboxes osboxes 4096 Jan 20 18:03 bin

-rw-r-----. 1 osboxes osboxes 763 Jan 20 18:04 startManagedWebLogic_readme.txt

-rwxr-x---. 1 osboxes osboxes 293 Jan 20 18:04 startWebLogic.sh

drwxr-x---. 2 osboxes osboxes 63 Jan 20 18:04 nodemanager

drwxr-x---. 2 osboxes osboxes 4096 Jan 20 18:04 init-info

drwxr-x---. 2 osboxes osboxes 167 Jan 20 18:04 security

drwxr-x---. 9 osboxes osboxes 213 Jan 20 18:04 config

Step 9) On machine1: start the NodeManager and AdminServer

[osboxes@machine1 bin]$ nohup ./startWebLogic.sh &

[1] 117208

[osboxes@machine1 bin]$ nohup: ignoring input and appending output to 'nohup.out'

[osboxes@machine1 bin]$ nohup ./startNodeManager.sh &

[3] 116976

[osboxes@machine1 bin]$ nohup: ignoring input and appending output to 'nohup.out'

[osboxes@machine1 bin]$ tail -f nohup.out

coherence.startup.JavaHome=/home/osboxes/jdk-11.0.9

coherence.startup.MW_Home=

Domain name mappings:

base_domain -> /home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain

Step 10) On machine2: update the nodemanager.properties

PropertiesVersion=14.1.1.0.0

ListenAddress=192.168.1.197

Step 11) Enroll NodeManager on machine2

cd /home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/bin

[osboxes@machine2 bin]$ . ./setDomainEnv.sh

[osboxes@machine2 base_domain]$ java weblogic.WLST

Step 12) On machine2 Start the NodeManager

[osboxes@machine2 bin]$ nohup ./startNodeManager.sh &

[1] 8314

[osboxes@machine2 bin]$ nohup: ignoring input and appending output to 'nohup.out'

[osboxes@machine2 bin]$ tail -f nohup.out

coherence.startup.JavaHome=/home/osboxes/jdk-11.0.9

coherence.startup.MW_Home=

Domain name mappings:

base_domain -> /home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain

Step 13) Create a machine - Machine_2 . Create ManagedServer_3 and ManagedServer_4 from the console . Add ManagedServer_3 , ManagedServer_4 to the Machine_2 and Cluster_1

Step 14) Restart AdminServer which is running on machine1

Step 15) Start all the managed Servers configured on machine1 & machine2

Machine 1:

cd /home/osboxes/Oracle/Middleware/Oracle_Home/user_projects/domains/base_domain/bin

[osboxes@machine1 bin]$ nohup ./startManagedWebLogic.sh ManagedServer_1 t3://machine1:9001 &

[2] 118685

[osboxes@machine1 bin]$ nohup: ignoring input and appending output to 'nohup.out'

[osboxes@machine1 bin]$ nohup ./startManagedWebLogic.sh ManagedServer_2 t3://machine1:9001 &

[3] 118770

[osboxes@machine1 bin]$ nohup: ignoring input and appending output to 'nohup.out'

Machine 2:

Note :Refer the below link to setup boot.properties file if you don't want to enter user name and password on the terminal and you can run the script on the back ground after boot identity has been set.
