WBSVR53

DATES:

1. Featureset
   • Instructor to present client environments well prepared for an Apache Server installation.
2. Installation and Configuration
   • Install Apache server.
   • Perform a minimal configuration and implement and configure caching on the server.
   • Apache HTTP server version 2.2 mod_cache and mod_file_cache are no longer designated as experimental and can be used in a production environment.
   • Caching architectures need to be initialized and configured to accelerate HTTP handling both as a origin web and proxy server.
3. Security
   • Create a user-based authentication with Apache.
   • A command executed by root needs to be protected from modification by non-root users.
   • Accordingly, it will be necessary to ensure that the files, directories, and their parent directories and files are writeable only by root.
4. Delivering Dynamic Web Content
   • Install and configure web support for CGI.
   • In order for CGI programs to work properly, it will be necessary to configure Apache to permit CGI execution. There are several ways to do this.
   • Use the ScriptAlias directive to instruct Apache that a designated directory is to be set aside for CGI programs.
   • Apache will assume that every file in the designated directory will be CGI program and attempt to execute it, when that particular resource is requested by a client.
   • It will also be necessary to verify that Apache support for CGI.
5. Virtual Hosts, Redirection, and Indexing
   • IP-based virtual hosts use the IP address of the connection to determine the correct virtual host to be served. It will be necessary to setup a separate IP address for each host.
   • With name-based virtual hosting, the server relies on the client to report the hostname as part of the HTTP headers. This technique can be used to have several different hosts share the same IP address.
6. Proxy Servers and Firewalls
   • The and containers apply enclosed configuration directives only to sites accessed through the mod_proxy's proxy server that matches the specified URL.
   • Setup the server to prevent the proxy server from being able to access a specific website. The instructor will designate a website which is not permitted to be accessed from the server.
7. Monitoring Apache Web Server
   • Code a script to search the error log for a specific type of problem.
8. Improving Performance
   • Determine whether and where the server has a performance issue.
   • Use system commands to search the log and monitor the system.
   • Develop a plan for improving performance.
9. Starting and Stopping
   • Check for start up errors in the server.
   • Change the start-up procedure for starting Apache at boot time.
   • In order to stop or restart Apache, it will be necessary to send a signal to the running httpd processes; this can be done by sending signals.
   • Use the UNIX kill command to send signals directly to the parent processes.
