Installing Apache Web Server and Tomcat Servlet Engine

• Apache Web Server and Tomcat Servlet engine are installed with most configurations of OES Linux. If necessary, they can also be installed later using YaST.

Managing Apache Web Server

• To manage Apache Web Server, use the httpd.conf and various configuration directories beneath /etc/apache2.

• Apache Web Server can also be managed using the HTTP Server module in YaST.

• Virtual Hosting should be used to add custom content to the existing instance of Apache used for OES administration.

• Use the Apache Server logs to view errors and access attempts. Important log files include

  • /var/log/apache2/access_log

  • /var/log/apache2/error_log

Managing Tomcat Servlet Engine

• Use the Tomcat logs to view configuration information and errors. Important log files for Tomcat are

  • /var/log/apache2/mod_jk.log

  • /var/opt/novell/tomcat4/logs/catalina.out

  • /var/opt/novell/tomcat4/logs/localhost_log.*

This chapter looks at Apache Web Server and Tomcat Servlet Engine. Together, they form the foundation necessary for delivering web services on the OES Linux platform:

• Apache Web Server Apache Web Server is an open-source (read: free) web server that is responsible for serving more than 60% of all web content on the Internet. In OES Linux, Apache provides support for all OES Linux web-based management tools, and support for regular web server functionality for providing web services and applications.

• Tomcat Servlet Engine Tomcat was developed by the same folks who gave us Apache and is used to serve web applications. As with Apache, Tomcat is used internally for OES Linux web-based management tools, and can be used externally to provide web-based services.

Several powerful OES Linux services rely on Apache and Tomcat, including

• iManager

• iFolder

• iPrint

• QuickFinder

• Virtual Office

The following sections will discuss Apache Web Server and Tomcat Servlet Engine and their possibilities with OES Linux.
