Install & Configure LB on Apache (Steps using Glassfish v2ur1 & Apache 2.0.59 on Windows)

In Glassfish 9.1.1, LB installation was done using the AS installer.
The installer would edit the Apache config files as well. But,
Glassfish v2 ur1 does not have LB bundled with it. The users will have
to download the LB and manually configure it. Hence this blog, which
gives you detailed steps to install LB and configure it with Apache. If
you are using the Sun WebServer, the steps are available here

    device-host/common-name for certificate are the same}
    
    
    
  • 
    mkdir
    <apache-install>/conf/ssl.crt and
    <apache-install>/conf/ssl.key

  appears in the log .}
  
  
  

Install Glassfish v2ur1.

• 
  Download bits from

• 
  Create sub-directories in
  <Apache-install>/modules directory as - resource  and errorpages
  
  
  
• 
  Create sub-directory in
  <Apache-install> directory as - sec_db_files
  
  
  
• 
  cp
  <glassfish>/lib/plugin/lib/webserver-plugin/windows/apache2/LBPlugin*.res
  <Apache-install>/modules/resource/
  
  
  
• 
  cp
  <glassfish>/lib/plugin/lib/webserver-plugin/windows/apache2/mod_loadbalancer.dll
  <Apache-install>/modules/
  
  
  
• 
  cp
  <glassfish>/lib/plugin/lib/webserver-plugin/windows/apache2/errorpages/*
  <Apache-install>/modules/errorpages/
  
  
  
• 
  cp
  <glassfish>/lib/plugin/lib/install/templates/loadbalancer.xml.example
  <Apache-install>/conf/

• 　　Append httpd.conf file with:
  
  
  ##BEGIN EE LB Plugin Parameters
  LoadModule apachelbplugin_module modules/mod_loadbalancer.dll
  <IfModule mod_apache2lbplugin.cpp>
  config-file "C:/Program Files/Apache Group/Apache2/conf/loadbalancer.xml"
  locale en
  </IfModule>
  <VirtualHost 10.12.8.107>
  DocumentRoot "C:/Program Files/Apache Group/Apache2/htdocs"
  ServerName vm07
  </VirtualHost>
  ##END EE LB Plugin Parameters
  
• 
  Double-check apache-install
  location and the fully qualified machine name for ServerName in
  httpd.conf
  
  
  
• 
  cp
  <glassfish>lib/plugin/lib/webserver-plugin/windows/apache2/*.db
  <Apache-install>/sec_db_files/
