The Challenege: Moving one of our MySQL database servers to a new machine. Database is live and under constant heavy load, 80GB in size, with 5,000+ tables. Taking the machine down for 'scheduled maintenance' is not an option. With the database handling financial transactions and campaign stats tracking, we couldn't afford any mistakes or the slightest chance of data loss. Suggested solutions:

T his is a simple backup solution for people who run their own web server and MySQL database server on a dedicated or VPS server. Most dedicated hosting provider provides backup service using NAS or FTP servers. These service providers will hook you to their redundant centralized storage array over private VLAN. Since, I manage couple of boxes, here is my own automated solution.
MySQL is one of the most popular database management systems for the development of interactive Websites that need to utilize persistent data sources. As with all other popular database management systems, MySQL offers several methods to backup your important data. In this article we’ll look at how to backup your databases using the mysqldump utility that comes with MySQL. We’ll review several examples using mysqldump, including the backup of your database to a file, another server, and even a compressed gzip file. I’ll assume that you have MySQL installed locally on a Windows, Unix or Linux machine, and that you have administrative privileges on that machine. I’ll also assume that you’ve had at least a small amount of exposure to MySQL and the SQL language syntax.
Q . I’m new to Linux and I’ve dedicated VPS server running Ubuntu Linux. I’m using CMS software and MySQL act as database server.

As I started moving forward with a plan to host Satchmo on my own, I began experimenting with hosting solutions. I already had a traditional hosting service and was able to get Satchmo running as a fast cgi. It worked reasonably well, but the control was less than optimal.

When you delete large portions for data from your MySQL table, the database becomes more fragmented. It is always a good idea to re-optimize your MySQL database especially if you have a lot of varying characters (VARCHAR). Here’s the command to optimize just one table: But I am looking for a more command line solution and here it is:
MySQL is one of the most popular database management system that powers the most dynamically served website, including sites with millions traffic and visitors everyday. Many web pages and web applications or services rely on MySQL to store contents data which will be retrieved and read by web servers to dynamically built the web pages that visitors will read. As each visit will mean that web server is required to access the MySQL database server at least once to assemble, build and serve the page to reader, so the performance of MySQL server is very important and essential to the overall speed of website, especially on the busy and heavy loaded web host. To improve the performance of MySQL databases, optimize, or know how to optimize MySQL is a needed skill. Jay Pipes had given a talk during Google TechTalks in April 28, 2006 on best practices and techniques for performance tuning for MySQL DB server.

When you are working on increasing the speed of your website, a very important piece is making sure you get every last drop of performance out of your database server. Unfortunately, for most of us that aren’t normally database administrators this can be a difficult proposition. There’s a number of performance tuning scripts that will analyze your server settings and current status and give you information on recommended changes that you should make. You shouldn’t necessarily follow all of the suggestions, but it’s worthwhile to take a look at anyway. The script I’ve been using gives you recommendations for the following: Slow Query Log Max Connections Worker Threads Key Buffer Query Cache Sort Buffer Joins Temp Tables Table (Open & Definition) Cache Table Locking Table Scans (read_buffer) Innodb Status
Mar 15 2009 MySQL is one of the most popular open source database management system for the development of interactive Websites. If your site stores its sensitive data in a MySQL database, you will most definitely want to backup that information so that it can be restored in case of any disaster (we all have been there). There are several ways to backup MySQL data. In this article we’ll look at how to backup your databases using different methods, we will also learn how to achieve an automatic backup solution to make the process easier.
