Apache Web Server guide

Apache Web Server guide

Apache has been the most popular Web server in the world since 1996, and continues to grow at a fast rate. The free open source product is capable of a high level of security and is suitable for both small and large websites. Apache Web Server’s flexibility to run on a variety of operating systems, and the ongoing development by dedicated programmers have allowed it to stand the test of time and keep up with its competitors. In this guide, we’ll present a collection of tips that can help administrators setup and configure an Apache Web Server on Enterprise Linux, and offer advice on how to use other open source tools to monitor and improve Apache performance.

Installing and configuring Apache

Migrating Microsoft Internet Information Server to Apache on Red Hat Linux
Making the change from Windows to Linux can be a difficult process for anyone, but can be especially challenging for administrators moving from Microsoft Internet Information Server to Apache. This type of migration involves more than just copying files, but a well thought-out procedure can streamline the process.

Linux sendfile and Apache servers: How an underused feature can offset overused resources
Administrators can squeeze even moreperformance out of Apache servers by utilizing the Linux sendfile() system call, an underused tool that can bring performance benefits to an Apache server handling large data transfers. The sendfile() system call can duplicate data more efficiently than typical read() /write() calls. Using this data transfer approach can avoid needless operations and improve overall system performance.

Securing an Apache Web server with SELinux
While disabling SELinux makes it easier to deliver service, it also increases security risks. Using SELinux with your Apache Web Server can ensure hackers are not able to seriously damage your website. In this tip, learn three commands three commands for managing SELinux operations while maintaining security.

Open source tools to monitor Apache performance

Using open source tools to monitor Apache Web Server performance
Apache provides a popular and stable platform for business websites, but keeping those sites running smoothly requires close monitoring and tracking. There are a variety of open source monitoring tools that can make the job easier. Apache Bench, Nikto and Piwik can help administrators optimize performance and minimize downtime. In this tip, you will learn how these three tools can be used to track Apache Web Server performance and security.

Nagios setup: Installing and configuring the network monitoring tool
Nagios is one of the most popular open source monitoring tools – and for good reason. It can be used to monitor a wide variety of devices and operating systems, including all major Linux distributions. On an Apache Web Server, Nagios can monitor a wide variety of important information, including requests per second, bytes per second and its CPU load. Learn how to install and configure Nagios to improve your Web server performance.

Use Nagios to trend and troubleshoot performance issues
Administrators can’t keep an eye on server performance 24/7, but they should have a way of tracking performance that can notify them of potential problems. While Nagios won’t improve Apache Web Server performance on its own, the data it gathers can help administrators identify and track performance problems on your networks. In this tip, an expert writes about how Nagios can identify performance problems and explains how the tool’s reports can be used to improve performance.

How to install and configure MRTG, an essential sys admin tool
The Multi Router Traffic Grapher (MRTG) can graph network traffic and other useful data that can be collected with Simple Network Management Protocol or custom scripts, making it a valuable tool for busy administrators. However, if administrators are unfamiliar with its use, it can be difficult to configure. In this tip, an expert explains how install and configure MRTG to begin monitoring network traffic.
