This document outlines a short course on installing the Tungsten Replicator using MySQL, including prerequisites and installation methods. Topics covered include architecture, pre-installation decisions, and a demonstration of installation methods, detailing both ini-based and staging installations. It also provides resources and contact information for further assistance and inquiries.
Training Slides: Basics 107: Simple Tungsten Replicator Installation to Extract from MySQL
- 1. Basics : Simple Replicator Installation Extract from MySQL
- 2. Topics In this short course we will: • Review the Replicator • Review prerequisites required • Discuss installation Methods – Staging vs INI • Walkthrough an Installation (Full end to end demo) • Recap Key Resources and Tools Course Prerequisite Learning – Basics: Introduction to Tungsten Replicator – Visit Continuent website or Tungsten University on YouTube to watch these recordings 2

- 5. Key Decisions and Prerequisites
- 6. Pre Installation Environment Decisions • Which release of MySQL? – MySQL Community – Percona – MariaDB – Oracle MySQL Enterprise • Which version? – 5.0 to 5.7 • What monitoring tools do you have? • Full or Partial Replication • What backup tools do you have? 6
- 7. Prerequisities • Review docs – http://docs.continuent.com/tungsten-replicator-5.3/prerequisite.html • Host Prerequisites – OS user – /etc/hosts – sudoers and ssh – Ruby – Java • Network Prerequisites – Review port requirements • MySQL Prerequisites – my.cnf settings – tungsten user accounts 7
- 8. Pre Installation Tungsten Decisions • TAR file or RPM? • INI-based install or staging install? • SSL Enabled? 8
- 9. Installation Methods: ini vs staging • INI-based Install – Install managed via /etc/tungsten/tungsten.ini on EACH host – PROS • Control over each node individually • Easy integration to automation software such as puppet and chef • Remove dependency on single host for install – CONS • Configuration changes must be performed individually • Risk of misconfiguration between nodes 9
- 10. Installation Methods: ini vs staging • Staging Install – Install managed from one host – Could be a source/target node or a separate host outside of replication. – PROS • One single place for configuration • Easy to install/update entire topology in one go • Configuration applied to all nodes, less risk of misconfiguration – CONS • No easy integration to automation software • Staging host become single point of failure for configuration management – Especially important if Staging host is a DB Node 10
- 11. Installation Demo DBMS Logs Download transactions via network Apply using JDBC THL = Events + Metadata MySQL MySQL Binary Logging Option 1: Local Install Extractor reads directly from the logs, even when the DBMS service is down. This is the default. Option 2: Remote Extractor gets log data via MySQL Replication Slave protocols (which requires the DBMS service to be online). This is how we handle RDS extraction tasks. Extractor Options Master Replicator: Extractor THL 2 1 Slave Replicator: Applier THL MySQL
- 13. Tools : trepctl 13 • “trepctl status” can be run from any node to view the status of the local replicator • “trepctl status –r 3” will show status output refreshed every 3 second until CTRL+C • “trepctl qs” provides a quick summary overview of the local replicator • “trepctl perf” provides deeper diagnostics of the different stages in the replicators $ trepctl qs State: east Online for 21.069s, running for 45.654s Latency: 0.837s from DB commit time on db1 into THL 21.839s since last database commit Sequence: 1 last applied, 0 transactions behind (0-1 stored) estimate 0.00s before synchronization
- 14. Log Files 14 • The /opt/continuent/service_logs/ directory contains both text files and symbolic links. • Links in the service_logs directory go to following subdirectory: – /opt/continuent/tungsten/tungsten-replicator/log/ tungsten@db1:/opt/continuent/service_logs $ ll total 116 lrwxrwxrwx 1 tungsten tungsten 60 Jan 06 09:52 trepsvc.log -> /opt/continuent/tungsten/tungsten-replicator/log/trepsvc.log
