How To Set Up Database Replication In MySQL On Ubuntu 9.10

Post date: January 12, 2010, 12:01 Category: Miscellaneous Views: 3554 Comments
Tutorial quote: This tutorial describes how to set up database replication in MySQL. MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures.

How To Set Up Database Replication In MySQL

In this tutorial I will show how to replicate the database exampledb from the master with the IP address 192.168.0.100 to a slave. Both systems (master and slave) are running Debian Sarge; however, the configuration should apply to almost all distributions with little or no modification.

Have a Bash With This Linux Shell

Post date: April 15, 2005, 05:04 Category: Programming Views: 3965 Comments
Tutorial quote: Any Linux administrator who wishes to remain sane relies heavily on scripting to automate routine tasks, customize jobs, and build the plumbing that connects the different utilities that make a Linux system run smoothly. The Linux world is chock-full of scripting languages: Perl, Python, PHP, Scheme, Tcl, Tk, Ruby, Forth, Smalltalk, Eiffel, and doubtless many more. To get the column started, we'll look at shell scripting with Bash, and scripting with Python and Perl.

How To Implement SPF In Postfix

Post date: February 25, 2007, 21:02 Category: Miscellaneous Views: 5447 Comments
Tutorial quote: This tutorial shows how to implement SPF (Sender Policy Framework) in a Postfix 2.x installation. The Sender Policy Framework is an open standard specifying a technical method to prevent sender address forgery. There are lots of SPF extensions and patches available for Postfix, but most require that you recompile Postfix. Therefore we will install the postfix-policyd-spf-perl package from openspf.org which is a Perl package and can be implemented in existing Postfix installations (no Postfix compilation required).

Installing Popular Applications On Your Ubuntu Desktop With Automatix2

Post date: December 5, 2006, 20:12 Category: Desktop Views: 3712 Comments
Tutorial quote: Although Ubuntu comes with lots of applications that can be installed on your desktop, there are still some applications that are available only from third-party repositories. Finding all these repositories and installing these applications manually is very time-consuming, but fortunately some people have created a script called Automatix2 (which is the successor to Automatix) which automates the task for you. It comes with a graphical interface so that you can run it from your desktop, and this tutorial describes how you do it.

How To Set Up MySQL Database Replication With SSL Encryption On CentOS 5.4

Post date: February 18, 2010, 13:02 Category: Miscellaneous Views: 5430 Comments
Tutorial quote: This tutorial describes how to set up database replication in MySQL using an SSL connection for encryption (to make it impossible for hackers to sniff out passwords and data transferred between the master and slave). MySQL replication allows you to have an exact copy of a database from a master server on another server (slave), and all updates to the database on the master server are immediately replicated to the database on the slave server so that both databases are in sync. This is not a backup policy because an accidentally issued DELETE command will also be carried out on the slave; but replication can help protect against hardware failures.
