User wasuser

Group wasgroup

- Go to /IBM/HTTPServer/bin, and run "adminctl start" and "apachectl –k start" to start IHS server.

Configure IHS Web Server on WAS or WPS

After installing IHS Web Server, we need to create a web server on WAS so that the application deployed on WAS server can be mapped to web server.

-          Logon to server WAS_HostServer with user "wasuser", the user is used to run WebSphere Application Server instances

-          Go to directory /IBM/WebSphere/AppServer/bin

-          Download the file "configurewebserver1.sh" from IHS_HostServer, the file is at /IBM/HTTPServer/Plugins/bin

-          Edit the last line configurewebserver1.sh like this:

./wsadmin.sh $PROFILE_NAME_PARAMETER $WSADMIN_USERID_PARAMETER $WSADMIN_PASSWORD_PARAMETER -f $WAS_HOME/bin/configureWebserverDefini

tion.jacl webserver1 IHS '/IBM/HTTPServer' '/IBM/HTTPServer/conf/httpd.conf' 80 MAP_NONE'/IBM/HTTPServer/Plugins' unmanaged webserver1-node  blue-devweb01.mtsallstream.com aix 8008  ihsadmin $IHS_ADMIN_PASSWORD_PARAMETER

I recommend to use "MAP_NONE" to replace "MAP_ALL".

-          Run the shell script

configurewebserver1.sh cellName  userid userpassword ihsadmin

userid and userpassword should be specified if global security is enabled.

-          logon to administrative console, then synchronize the nodes

-          Go to servers->server Types-> web servers, if the web server is running on IHS_Host, then the server status is running

-          if webserver1 status is stopped, we can start the web server1 through administrative console if http admin process is running on blue-devweb01.

-          Make the ihsadmin username and password is entered. Click "webserver1", then click "Remote Web server management" at the right side. assure the port number, username and password are correct

-          Then select "webserver1" and click "Start" button to start web server, the server should be started.

-          Select "webserver1" and click "Generate Plug-in", and then select "webserver1" again and  click "Propagate Plug-in". we may see the following error:

"PLGC0049E: The propagation of the plug-in configuration file failed for the Web servers xxxxxxxxxx

-          the reason why it happened it because the permission issue

-          logon to server IHS_Host with user "wasuser"

-          go to directory /IBM/HTTPServer/Plugins/config/webserver1

-          make sure plugin-cfg.xml permission is 755 or 664

-          go to directory /IBM/HTTPServer/conf

-          edit the conf file admin.conf as following:

User wasuser

Group wasgroup

-          switch to root user

-          Go to directory /IBM/HTTPServer/bin

-          restart admin process: ./adminctl stop and ./adminctl start

-          the issue should be solved.a
