Configuring Apache for Maximum Performance

Post date: February 12, 2006, 09:02 Category: Optimizing Views: 3837 Comments
Tutorial quote: Apache is an open-source HTTP server implementation. It is the most popular web server on the Internet; the December 2005 Web Server Survey conducted by Netcraft [1] shows that about 70% of the web sites on Internet are using Apache.

Apache server performance can be improved by adding additional hardware resources such as RAM, faster CPU, etc. But most of the time, the same result can be achieved by custom configuration of the server. This article looks into getting maximum performance out of Apache with the existing hardware resources, specifically on Linux systems. Of course, it is assumed that there is enough hardware resources - especially enough RAM that the server isn't swapping frequently. First two sections look into various Compile-Time and Run-Time configuration options. The Run-Time section assumes that Apache is compiled with prefork MPM. HTTP compression and caching is discussed next. Finally, using separate servers for serving static and dynamic contents is covered. Basic knowledge of compiling and configuring Apache and Linux are assumed.

Postfix performance tuning

Post date: May 21, 2005, 11:05 Category: Optimizing Views: 3451 Comments
Tutorial quote: Postfix is fast out of the box, but like other packages, you can usually tune it to work even faster. Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems.

How To Block Spam Before It Enters The Server (Postfix)

Post date: June 4, 2007, 23:06 Category: Security Views: 4277 Comments
Tutorial quote: The last few weeks have seen a dramatic increase in spam (once again). Estimates say that spam makes now up for 80 - 90% of all emails, and many mail servers have difficulties in managing the additional load caused by the latest spam, and spam filters such as SpamAssassin do not recognize large parts of that spam as they did before. Fortunately, we can block a big amount of that spam at the MTA level, for example by using blacklists, running tests on the sender and recipient domains, etc. An additional benefit of doing this is that it lowers the load on the mail servers because the (resource-hungry) spamfilters have to look at less emails.

Using Ruby On Rails With Apache2 On Debian Etch

Post date: May 27, 2007, 23:05 Category: System Views: 3706 Comments
Tutorial quote: This article shows how you can install Ruby on Rails (RoR) and integrate it in Apache2 on a Debian Etch system. Ruby on Rails is a web application framework which is rapidly gaining popularity among web programmers. It aims to increase the speed and ease with which database-driven web sites can be created and offers skeleton code frameworks (scaffolding) from the outset. Applications using the RoR framework are developed using the Model-View-Controller design pattern.

ACL(Access Control List) Configuration

Post date: April 4, 2006, 20:04 Category: Installing Views: 3101 Comments
Tutorial quote: Access Control Lists (ACLs) provide a much more flexible way of specifying permissions on a file or other object than the standard Unix user/group/owner system. Windows NT and above, when running on an NTFS partition, use ACLs to specify permissions on files and directories. This document attempts to show how you can enable ACL support on your Linux box and use Samba to provide an SMB file server for use by machines in a Windows 2000 domain.

ACLs are best stored in the actual file system itself. To that end, there are patches available for ext2 and ext3 that enable ACL support using Extended Attributes (EAs). SGI's XFS also has ACL support built in, but XFS is not currently covered in this document.
