How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10

Comments: 3 How To Set Up MySQL Database Replication With SSL Encryption On Ubuntu 9.10 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 though.

Comments: 4 How To Set Up An SSL Vhost Under Apache2 On Ubuntu 9.10/Debian Lenny This article explains how you can set up an SSL vhost under Apache2 on Ubuntu 9.10 and Debian Lenny so that you can access the vhost over HTTPS (port 443). SSL is short for Secure Sockets Layer and is a cryptographic protocol that provides security for communications over networks by encrypting segments of network connections at the transport layer end-to-end. We use the mod_ssl Apache module here to provide strong cryptography for Apache2 via SSL by the help of the Open Source SSL toolkit OpenSSL.
