Over the course of the past year, we have covered many dedicated server maintenance issues, particularly for servers running Linux. 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).

Web hosting is a vast subject, and we have covered many areas of the topic over the past year. Here are a few tips to help you keep your server in the best web hosting shape possible.

1. Keep backups of all data, both account storage and databases. If possible, keep the backups on a remote server and schedule regular incremental updates

2. Update the kernel and other software regularly.

3. Use a script installation service to help users install web applications

4. Provide a web-based control panel to help users manage their sites

5. Enforce strong passwords and encourage users to update their passwords regularly

6. Use a monitoring service for the web server, mail server, database server, and any other critical services

7. Maximize disk and memory usage only to the point of ideal performance and do not over exert the server

8. Always announce any changes, updates, reboots, or maintenance, giving users plenty of time adjust.

How to Remove Software in Linux

Wed, 14 Jul 2010 19:22:06 +0000

Question: How do I remote software that I installed from my Linux dedicated server?

Answer: The answer to that question depends on how you installed the software in the first place. Once you establish how and where the software has been installed, you can determine how to remove it.

1. Package Manager – Most software should be installed with a package manager like YUM or Apt. If that is the case, you remove it with the normal command for the package manager:

yum remove [packagename] apt-get remove [packagename]

2. Manual Deb, RPM, etc – If you installed a distribution package manually, you can remove it manually or use your package manager to remove it.

3. Binary Archive – If you were given a tar.gz or similar package with binaries inside, and you unpacked them to a directory, simply remove the directory. If the package had an installer program, try using that to uninstall it.

4. Source – If you compiled the software from source and used “make install” to install it, removing it may be more tricky. If you still have the source files, you can simply run “make uninstall”. Otherwise, you will have to find out where the files were installed and remove. They may be in several directories.

Fast control panel script installation

As the web hosting industry becomes more competitive, web hosting providers need to provide extra services and features to stand out from the rest. One common service that numerous hosts offer is script installation. Usually managed in the host’s control panel, users can use the service to automatically install content management systems, photo galleries, forums, and other web-based software.

Ideally, script installation should be fast, easy to use, and should be simple and direct, avoiding any hacks that make the installations incompatible with normal installations (in case the user ever needs to move their data to another server). But not all hosts are equal in these areas.

Go Daddy, for example, is a well known and highly advertised host, but their control panel scripts installation is mediocre at best. When a user sets up an installation of a script, Go Daddy’s control panel will queue it and make the user wait an undetermined amount of time before the script is actually installed. It is very slow and can be frustrating to a website owner who purchased an account expecting clean and fast script installation.
