Mysql Replication Tutorial
MySQL Replication Tutorial Lars Thalmann Technical lead Replication, Backup, and Engine Technology Mats Kindahl Lead Developer Replication Technology MySQL Conference and Expo 2008 Concepts 3 MySQL Replication Why? How? 1. High Availability Snapshots (Backup) Possibility of fail-over 1. Client program mysqldump 2. Load-balancing/Scale- With log coordinates out 2. Using backup Query multiple servers InnoDB, NDB 3. Off-site processing Don’t disturb master Binary log 1. Replication Asynchronous pushing to slave 2. Point-in-time recovery Roll-forward Terminology Master MySQL Server • Changes data • Has binlog turned on Master • Pushes binlog events to slave after slave has requested them MySQL Server Slave MySQL Server • Main control point of replication • Asks master for replication log Replication • Gets binlog event from master MySQL Binary log Server • Log of everything executed Slave • Divided into transactional components • Used for replication and point-in-time recovery Terminology Synchronous replication Master • A transaction is not committed until the data MySQL has been replicated (and applied) Server • Safer, but slower • This is available in MySQL Cluster Replication Asynchronous replication • A transaction is replicated after it has been committed MySQL Server • Faster, but you can in some cases loose transactions if master fails Slave • Easy to set up between MySQL servers Configuring Replication Required configuration – my.cnf Replication Master log-bin server_id Replication Slave server_id Optional items in my.cnf – What -

Tools for Managing Mysql 1
Tools for Managing MySQL 1 Tools for Managing MySQL The MySQL database engine comes with command-line tools to manage the data structures, user security and to add, drop and modify records in the databases. It's worthwhile to learn enough about these tools, since you can be assured they'll be available in every installation, and “one quick change” is much faster in a text-based tool. However, for much of your daily work, you may find that some graphical 3rd party tools make the work easier, more productive and more pleasant. Moving to MySQL means that you'll need to learn to work with the tools included with MySQL database for maintenance, security, monitoring and data access. It's wise to get familiar with the basic set of command-line tools, as you never know when you may find yourself with a minimal installation to manage or a slow dial-up connection to your server. You will also want to consider some of the very attractive add-on tools that can make the job easier. This chapter starts by covering the basic tools,and then shows some of the other utilities available for downloading. At a minimum, programmers should be familiar enough with a command-line interface to feel comfortable using it for some work. Some will find that the shell interface is all that's needed. A quick and simple change can be easily implemented that way. However, when learning a new tool, nothing beats the “explorability” of a graphical interface to discover what sorts of features and options are available. -
Mariadb Presentation
THE VALUE OF OPEN SOURCE MICHAEL ”MONTY” WIDENIUS Entrepreneur, MariaDB Hacker, MariaDB CTO MariaDB Corporation AB 2019-09-25 Seoul 11 Reasons Open Source is Better than Closed Source ● Using open standards (no lock in into proprietary standards) ● Resource friendly; OSS software tend to work on old hardware ● Lower cost; Usually 1/10 of closed source software ● No cost for testing the full software ● Better documentation and more troubleshooting resources ● Better support, in many cases directly from the developers ● Better security, auditability (no trap doors and more eye balls) ● Better quality; Developed together with users ● Better customizability; You can also participate in development ● No vendor lock in; More than one vendor can give support ● When using open source, you take charge of your own future Note that using open source does not mean that you have to become a software producer! OPEN SOURCE, THE GOOD AND THE BAD ● Open source is a better way to develop software ● More developers ● More spread ● Better code (in many cases) ● Works good for projects that can freely used by a lot of companies in their production or products. ● It's very hard to create a profitable company developing an open source project. ● Not enough money to pay developers. ● Hard to get money and investors for most projects (except for infrastructure projects like libraries or daemon services). OPEN SOURCE IS NATURAL OR WHY OPEN SOURCE WORKS ● You use open source because it's less expensive (and re-usable) ● You solve your own problems and get free help and development efforts from others while doing it. -
