In no particular order, here is a list of some of the more important tips you should remember when taking care of your server.

1. When possible, rely on the distribution updates and repositories. Only add third-party software when absolutely necessary.

2. Periodically run fsck to check the file system.

3. Monitor system and service logs.

4. Disable unused services.

5. Periodically optimize MySQL databases.

6. Monitor CPU and RAM usage.

7. Optimize RAM and swap usage.

8. On larger servers, run the database server on a separate machine, optimize the servers for scalability, and consider using a CDN (Content Delivery Network).

Add a second monitor to your computer for better domaining https://www.internetblog.org.uk/post/1471/add-a-second-monitor-to-your-computer-for-better-domaining/ Fri, 25 Jun 2010 22:18:16 +0000 http://www.internetblog.org.uk/post/1471/add-a-second-monitor-to-your-computer-for-better-domaining/ dual monitors
Monitors seem to get bigger and bigger every year. Whereas 17-inches used to be a normal screen size, now monitors as large as 24-inches are the norm. While having a big monitor makes getting work done easier, you can get an even bigger productivity boost from installing a second monitor on your computer.

If you register domains on a regular basis or build a lot of websites, you probably have multiple programs open all the time. Domainers work with a lot of data and often have to scramble to make a registration before someone else. Having two monitors allows you to see more data at once, increasing your efficiency. The same is true for web designers, but they also get the benefit for having an HTML editor in one window and the under-construction site in the other.

The best part about having dual monitors is the cost. Who says you have to go buy an expensive monitor? Repurpose a display from an old computer or buy a low-end model on sale at a local store. The amount of productivity you gain will pay for itself ten times over. As for me, I’m looking into adding a third monitor to my computer setup.

MySQL Enterprise Released https://www.internetblog.org.uk/post/1333/mysql-enterprise-released/ Wed, 19 May 2010 18:05:47 +0000 http://www.internetblog.org.uk/post/1333/mysql-enterprise-released/ Oracle logoMonday, the database giant, Oracle, announced the release of MySQL Enterprise. In addition to the standard, freely available database software, this new packaged version of MySQL will include comprehensive support and monitoring tools. The primary tool available with this release is MySQL Monitor 2.2, which monitors performance and security. Other important tools include the Query Analyzer and MySQL Connector Plugins.

“DBAs and developers need solutions that help them manage their MySQL servers efficiently and allow them to identify performance issues before they become expensive, time-consuming problems,” said Tomas Ulin, director, MySQL Development, Oracle.

MySQL is one of the most widely-used database servers on the Web, and most web hosting providers offer it. While the underlying code for the database software is free and open source, there is also a commercially licensed version. MySQL was owned by Sun Microsystems until Oracle recently bought Sun and all of its software products.

4 Tools to monitor site uptime https://www.internetblog.org.uk/post/1126/4-tools-to-monitor-site-uptime/ Tue, 23 Mar 2010 15:28:05 +0000 http://www.internetblog.org.uk/post/1126/4-tools-to-monitor-site-uptime/ Pingdom monitoring screenshot
One of the most important things you can do for your website is to make sure you have some type of monitoring. The last thing you want is to get an email or call from an irate customer because your site is down. Here are four web-based monitoring tools that alert you when your site is down. They also provide many other features, and one, Sucuri, checks your site for attacks and malware. They are listed here in no particular order.

Monitoring your server from your iPhone https://www.internetblog.org.uk/post/963/monitoring-your-server-from-your-iphone/ Thu, 04 Feb 2010 22:38:25 +0000 http://www.internetblog.org.uk/post/962/monitoring-your-server-from-your-iphone/ iPhone in hand
Picture this. You’re on the go, traveling, working, going on a date, or even just taking a nap, and you suddenly start getting phone calls. Little do you know that those phone calls are from angry customers or your boss. The server went down two hours ago, but you had no idea what was going on.

Many of us in the IT industry, particularly server administrators, have experienced a scenario like this one. It could be something small. Maybe Apache just needs a restart, but instead of it being a small issue, your stakeholders blow it out of proportion. Rather than getting upset with them and possibly losing your job, why not put your iPhone to use?

Root Internet, an Internet service company, offers an iPhone server monitoring tool. It pings HTTP, HTTPS, FTP, SSH, SMTP, DNS, POP3, IMAP, MySQL, and custom TCP/IP services that you specify. When your server experiences trouble, you will receive a notification on your iPhone, through email, and even a text message. Now you can rest easy and enjoy your vacation time – that is until the next disaster strikes.

What is MRTG? https://www.internetblog.org.uk/post/542/what-is-mrtg/ Fri, 02 Oct 2009 19:33:46 +0000 http://www.internetblog.org.uk/post/541/what-is-mrtg/ MRTG graph
Question: What is MRTG?

Answer: MRTG stands for Multi Rounter Traffic Grapher. It is free and open source software that monitors and measures traffic on a network. It provides a graph that shows traffic load over a set period of time. Although it was originally developed to monitor routers, many web hosting companies use it to keep track of bandwidth usage.

If you are a running a dedicated server, you will find MRTG very useful. With it, you can keep track of your site(s) bandwidth usage, high traffic times, and any anomalous spikes. MRTG is a Perl application and can run on numerous platforms, including Windows, Linux, Unix, Mac OS X, and Netware.

Users can download MRTG directly from the project’s website. It is also available in most Linux software repositories, making installation quick and painless. MRTG is available under the GNU General Public License.

Managing Linux System Programs and Processes https://www.internetblog.org.uk/post/475/managing-linux-system-programs-and-processes/ Thu, 10 Sep 2009 16:44:15 +0000 http://www.internetblog.org.uk/post/475/managing-linux-system-programs-and-processes/ TOP
Question: Something is hogging the CPU cycles on my Linux dedicated server. It has gotten really slow. How can I monitor running programs and processes?

Answer: Linux has a handy little tool called “top” that, when run, reveals your top running processes. It also gives you information about your memory usage, server load average, logged-in users, swap usage, uptime, and total number of tasks.

Running “top” is simple. Just login to your server via SSH and type “top”. It will tell you the PID of the process, the user running it, the amount of memory it is using, the cpu percentage, memory percentage, time running, and the command’s name.

If you do happen to find a runaway process, press “q” to exit top, and then kill the process by typing “kill xxxx”, replacing the “xxxx” with the process PID number. If you find a process running under a suspicious user, you might have a security breach. For that, top cannot help you, but at least you will be a step closer to solving your problem.
