Storing Files/Directories In Memory With tmpfs

Post date: December 9, 2008, 12:12 Category: Miscellaneous Views: 3598 Comments
Tutorial quote: You probably know that reading from RAM is a lot of faster than reading files from the hard drive, and reduces your disk I/O. This article shows how you can store files and directories in memory instead of on the hard drive with the help of tmpfs (a file system for creating memory devices). This is ideal for file caches and other temporary data (such as PHP's session files if you are using session.save_handler = files) because the data is lost when you power down or reboot the system.

Flip - Convert text file line endings between Unix and DOS formats

Post date: March 2, 2009, 07:03 Category: System Views: 3372 Comments
Tutorial quote: This program converts line endings of text files between MS-DOS and **IX formats. It detects binary files in a nearly foolproof way and leaves them alone unless you override this. It will also leave files alone that are already in the right format and preserves file timestamps.User interrupts are handled gracefully and no garbage or corrupted files left behind. ‘flip’ does not convert files to a different character set, and it can not handle Apple Macintosh line endings (CR only). For that (and more), you can use the ‘recode’ program (package ‘recode’).

Software RAID and Encrypted Filesystem Benchmarks

Post date: January 25, 2006, 23:01 Category: Benchmarks Views: 5455 Comments
Tutorial quote: Both tests use bonnie++ to test the disks.

- Files Test: create, destroy, and stat 20,000 files in sequential and random order. File sizes are random between 0K and 15k. All files are created in a single directory.
- IO Test: read, write, rewrite, and seek in three 1GB size files.
- Load: all tests are starting with 0 cpu load. Load was then measured every 2 seconds for the duration of the test and averaged over all measurements.

Make Browsers Cache Static Files With mod_expires On Apache2 (Debian Squeeze)

Post date: March 10, 2011, 11:03 Category: Installing Views: 3357 Comments
Tutorial quote: This tutorial explains how you can configure Apache2 to set the Expires HTTP header and the max-age directive of the Cache-Control HTTP header of static files (such as images, CSS and Javascript files) to a date in the future so that these files will be cached by your visitors' browsers. This saves bandwidth and makes your web site appear faster (if a user visits your site for a second time, static files will be fetched from the browser cache). This tutorial was written for Debian Squeeze.

How To Set Up A Load-Balanced MySQL Cluster

Post date: March 31, 2006, 19:03 Category: Software Views: 4360 Comments
Tutorial quote: This tutorial shows how to configure a MySQL 5 cluster with three nodes: two storage nodes and one management node. This cluster is load-balanced by a high-availability load balancer that in fact has two nodes that use the Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).

In this document I use Debian Sarge for all nodes. Therefore the setup might differ a bit for other distributions. The MySQL version I use in this setup is 5.0.19. If you do not want to use MySQL 5, you can use MySQL 4.1 as well, although I haven't tested it.

This howto is meant as a practical guide; it does not cover the theoretical backgrounds. They are treated in a lot of other documents in the web.

Zimbra Collaboration Suite Open Source Edition On CentOS

Post date: March 13, 2008, 11:03 Category: Installing Views: 6118 Comments
Tutorial quote: This tutorial shows how to set up Zimbra Collaboration Suite - Open Source Edition on CentOS. This tutorial covers installation of CentOS, dependencies for ZCS and setup of Split DNS when working behind a firewall. This tutorial is based on the way I set this server up and is only a suggestion. It carries no guarantees and it is highly suggested that you do this on a test server first to verify functionality. If you don't have a test server available you should download VMWare Server 1.0 and perform this tutorial on a test virtual server.

Splitting Apache Logs With vlogger

Post date: June 17, 2007, 22:06 Category: Software Views: 3997 Comments
Tutorial quote: Vlogger is a little tool with which you can write Apache logs broken down by virtual hosts and days. With vlogger, we need to put just one CustomLog directive into our global Apache configuration, and it will write access logs for each virtual host and day. Therefore, you do not have to split Apache's overall access log into access logs for each virtual host each day, and you do not have to configure Apache to write one access log per virtual host (which could make you run out of file descriptors very fast).
