Tune and Tweak NFS for Top Performance

Post date: June 26, 2005, 00:06 Category: Optimizing Views: 3397 Comments
Tutorial quote: As promised in our previous NFS article, we will now explore mount options in a bit more detail. We will also talk about differences between NFS implementations among various UNIX flavors, and the wonderful capability automatic mounting provides.

Postfix performance tuning

Post date: May 21, 2005, 11:05 Category: Optimizing Views: 3456 Comments
Tutorial quote: Postfix is fast out of the box, but like other packages, you can usually tune it to work even faster. Furthermore, there are situations where Postfix may not perform as well as you expected, whether because of hardware or software limitations on the server system or other adverse conditions, such as a big influx of spam or undeliverable mail. This article shows you how to find and analyze the most common performance problems.

Setting Up An NFS Server And Client On CentOS 5.5

Post date: September 28, 2010, 11:09 Category: Installing Views: 3701 Comments
Tutorial quote: This guide explains how to set up an NFS server and an NFS client on CentOS 5.5. NFS stands for Network File System; through NFS, a client can access (read, write) a remote share on an NFS server as if it was on the local hard disk.

Tweaking Hidden Ubuntu Settings With Ubuntu Tweak

Post date: January 29, 2008, 12:01 Category: Desktop Views: 4031 Comments
Tutorial quote: Ubuntu Tweak is a tool that lets you change hidden Ubuntu settings, for example: hide or change the splash screen, show or hide the Computer, Home, Trash, and Network icons, change Metacity, Nautilus, power management, and security settings, etc. Currently Ubuntu Tweak is available only for the Ubuntu GNOME desktop, i.e., it will not work on Kubuntu or Xubuntu. This short guide shows how to install and use Ubuntu Tweak.

Setting Up A Highly Available NFS Server

Post date: April 1, 2006, 05:04 Category: Network Views: 6322 Comments
Tutorial quote: In this tutorial I will describe how to set up a highly available NFS server that can be used as storage solution for other high-availability services like, for example, a cluster of web servers that are being loadbalanced. If you have a web server cluster with two or more nodes that serve the same web site(s), than these nodes must access the same pool of data so that every node serves the same data, no matter if the loadbalancer directs the user to node 1 or node n. This can be achieved with an NFS share on an NFS server that all web server nodes (the NFS clients) can access.

As we do not want the NFS server to become another "Single Point of Failure", we have to make it highly available. In fact, in this tutorial I will create two NFS servers that mirror their data to each other in realtime using DRBD and that monitor each other using heartbeat, and if one NFS server fails, the other takes over silently. To the outside (e.g. the web server nodes) these two NFS servers will appear as a single NFS server.

In this setup I will use Debian Sarge (3.1) for the two NFS servers as well as for the NFS client (which represents a node of the web server cluster).

High Performance MySQL

Post date: December 1, 2006, 04:12 Category: Optimizing Views: 5835 Comments
Tutorial quote: The operating system your MySQL server runs on and the server's configuration can be just as important to your server's performance as the indexes, schema, or queries themselves. In this chapter, we will help you understand how to tune your server to improve performance, as opposed to tuning schema or queries. We'll be looking at changes to your hardware, operating system, and MySQL configuration to see what effects they have on overall performance.

We assume that you've already made efforts to boost the performance of your queries. If you haven't done that already, stop now and read Chapter 4 and Chapter 5 to get a handle on optimizing your queries and your application code. Only then should you worry about server settings. Hardware is often not the solution to MySQL performance problems. Poorly optimized queries can slow you down far more than not having the latest CPU or SCSI disk. To put this in perspective, one of the MySQL AB trainers even says that changing hardware might, in the best cases, give you a 10-fold performance increase. But tuning queries (and schemas) can often give you 1000-fold performance increase. Seriously.

Some topics covered in this chapter are platform-specific. The authors' knowledge of the various platforms on which MySQL runs is limited. In many cases, you'll need to consult your local documentation for various operating system tools and specifics.

We start with an overview of the factors that limit performance and then look more in depth at RAID, hardware, and operating system issues. The chapter finishes with a discussion of techniques you can use to locate, identify, and fix bottlenecks.

Encrypted NFS with OpenSSH

Post date: May 21, 2005, 19:05 Category: Network Views: 2829 Comments
Tutorial quote: NFS is a widely deployed, mature, and understood protocol that allows computers to share files over a network. The main problems with NFS are that it relies on the inherently insecure UDP protocol, transactions are not encrypted, hosts and users cannot be easily authenticated, and its difficulty in firewalling. This article provides a solution to most of these problems for Linux clients and servers. These principles may also be applied to any UNIX server with ssh installed. This article assumes basic knowledge of NFS and firewalling for Linux.
