WCP 12.2.1: Installation VI (Oracle HTTP Server 12.2.1)

There are lot of differences between OHS 11g and OHS 12cR2 in the following:
  • In OHS 12cR2 you will not find the opmnctl command
  • In OHS 12cR2 Web Cache module as removed completily
  • OHS 12cR2 is added as a Component (like a "server") in WebLogic Domain and can be started using Node Manager (such another server)
  • Configuring OHS 12cR2 in a privileged port in UNIX is different from OHS 11g.
Here we are going to focus in how to start / stop and configure the port 80

Download the installer from the following URL: http://www.oracle.com/technetwork/middleware/webtier/downloads/index.html

Run the Universal Installer (now is .bin file do NOT use the java -jar command!)

OHS 12cR2 Universal Installer

Collocated option
In this case, we are going to installed Collocated with our WebLogic in order to be managed through Enterpise Manager.


Next -> Next -> Next... and we have it install it!.

Installation finished
It does not created an OHS instance... let's goes to do it

Create an OHS instance

Go to /oracle/product/oracle_common/common/bin and execute the Configuration Wizard. Now every product follows the same steps! :).


Select to update the domain created before:


Updating the existing domain

Important: Select the Collocated Oracle HTTP Server Template!

Configure the applications path for the OHS instance. Please, follow the best practices organizing folders!

Connect to the RCU configuration in DEV_STB table. Remember that we created it when installing the Oracle Fusion Middleware Infrastructure.

Add the ohs component to the dev_machine (Node Manager)

Adding the OHS component to the Node Manager
Finish the Configuration Wizard

 
Configuration Finished

Configure to listen port 80

This is one of the biggest changes from 11g and also changes from 12cR1. Configure it is well explained in: http://docs.oracle.com/middleware/1221/webtier/administer-ohs/getstart.htm#BEHDHFGE

  • Change the ownership of the launc script in [ORACLE_HOME]/ohs/bin/launchchown root [ORACLE_HOME]/ohs/bin/launch
  • Change the permission on the file as follows:
    chmod 4750 [ORACLE_HOME]/ohs/bin/launch
  • Modify the Listen port of httpd.conf to 80 (edit the file manually or do it through Enterprise Manager)
    Changing Port using EM
Re-start the OHS using your favourite mode (command or Enterprise Manager)

OHS started succesfuly

Start / Stop

Make sure that you have node manager and weblogic server running.

You have three options
  1. Using Enterprise Manager Console
    Start Up and Shut Down options
  2. Using command line
    [DOMAIN_HOME]/bin/startComponent.sh ohs-webcenter
  3. Using WLST Node Manager commands (such a server) with nmConnect and nmStart operations

Preconfigure the Virtual Hosts for WebCenter

Configure the mod_wl_ohs to access the WebCenter Suite. It can be done manually in the File system or thought Enterprise Manager.

Use this following snippet to pre-configure the Locations of WebCenter products

# NOTE : This is a template to configure mod_weblogic.

LoadModule weblogic_module   "${PRODUCT_HOME}/modules/mod_wl_ohs.so"

# This empty block is needed to save mod_wl related configuration from EM to this file when changes are made at the Base Virtual Host Level
