Shutting Down Linux Properly & Recovering After an Improper Shutdown – Linux System Admin Training
If a Linux system is not working properly and it “hangs” or if it loses power (due to a power failure or some other reason) – then the system has not been shut down “cleanly” (or “properly”). If a Linux system was not shut down cleanly, watch its screen as it starts again. Important information appears on the screen when a system starts. This can help you to diagnose and fix a problem. Be Sure To Shut Down A Linux System Properly (Cleanly) When you are finished working at a Linux system and need to turn the power off, you [...]
How To Automate Tasks In Your Linux Server
If your host is running under the Linux (Unix) operating system, you can perform tasks in the server on a regular basis. For example, sending mails at a certain time of the day, backing up database at 6 in the morning and so on. “Cron” is a program that runs in the background of the Linux server. The program runs certain commands defined by you at fixed time intervals. A tyical cron file will look something like this: # My Sample Cron File 12 01 02 * * /usr/bin/du /var > /home/test/diskSpace.txt Cron command lines consist of 6 whitespace separated [...]

Benefits of Server Virtualization
By utilizing server virtualization, a company’s computer system can run more efficiently, which generates cost savings for the company. Traditionally, one of these servers has run one operating system only. With virtualization, a single server can be essentially “split” into two or more. After the split, each of them can run it’s own operating system. The operating systems do not even have to be the same — one partition of the virtual server can run Windows XP, the other Linux. Server virtualization (also called Virtual Dedicated Server, or VDS) provides many benefits for the company. The first is simply cutting [...]

So at about 1am this morning, Burst.Net finally got my server up and running for me to use. Unfortunately for me, I was already sleeping and I had work today so I wasn’t able to actually play with it until tonight. Like other VPS’s and dedicated servers out there, the server is usually bare boned with no software except the operating system. For me I decided to use CentOS 5 64-bit edition to get my web server up and running. Burst.NET had Apache 2 pre-installed on my VPS for me but that was pretty much about it. So I had [...]

3 Reasons to Try Cloud Servers
Thousands of people around the world are now using cloud servers. I recently tried them and was blown away. If you have not tried them yet here are a few reasons why you should. Cloud servers are flexible allowing you to experiment and try new things. Most vendors allow you to startup a server and run it for as long as you want. This can be as little as a few minutes or much longer even permanent. I recently heard that Centos Linux version 6 was available and wanted to find out what the changes were and check out all [...]
