NOTE: Master note on Tungsten installation and setup: http://datacharmer.blogspot.com/2013/04/installing-and-administering-tungsten.html
Below are the steps I have used to setup Mysql replication using Tungsten
Please review the prerequisites for this installtion from https://code.google.com/p/tungsten-replicator/wiki/InstallationPreRequisites
1.) Install mysql on the master and slave hosts.
You can download mysql community edition from http://dev.mysql.com/downloads/mysql/
2.) Download tungsten from https://code.google.com/p/tungsten-replicator/downloads/list
I am using Tungsten Replicator 2.1.0 Binary Build.
3.) Login to mysql on master and slave as root user and create tungsten user and database:
grant all on *.* to 'tungsten'@'%' identified by 'secret' with grant option;
create database tungsten;
4.) Disable binlog_checksum
set global binlog_checksum=NONE;
This is required else you would receive following error while setting up tungsten:
ERROR >> host1 >> This instance is running with BinLog checksum enabled which is not yet supported (MySQLCheckSumCheck)
5.) Unzip and untar the Tungsten Replicator 2.1.0 downloaded in step 2. I use mysql OS user for all the setup.
tar -xzf tungsten-replicator-2.1.0-343.tar.gz
cd tungsten-replicator-2.1.0-343
6.) Tungsten configurations:
Setup environment:
export PATH=$PATH:$PWD/cookbook (eg. /home/mysql/tungsten-replicator-2.1.0-343/cookbook)
Update config files:
vi cookbook/COMMON_NODES.sh and update the hostnames
#!/bin/bash
# (C) Copyright 2012,2013 Continuent, Inc - Released under the New BSD License
# Version 1.0.5 - 2013-04-03
export NODE1=master01
export NODE2=slave01
Note: Incase you want to have multiple slaves add NODE3, NODE4....
vi cookbook/USER_VALUES.sh and update the TUNGSTEN_HOME locations, etc. This file will be used for installing tungsten components.
Validation before actual installation:
export VERBOSE=1
cd /home/mysql/tungsten-replicator-2.1.0-343 and the run the following command.
I had strange errors when I tried to run this command after going to /home/mysql/tungsten-replicator-2.1.0-343/cookbook. So make sure you are in tungsten-replicator-2.1.0-343 directory before trying the below command.
This command with read the values you updated in the files above and make sure there are no error. Incase of any errors it will notify you. I received the following errors:
After fixing these error the command was successful:
cookbook/validate_cluster
Installation of Master Slave topology:
Execute the below command. (Execute it from tungsten-replicator-2.1.0-343 directory)
cookbook/install_master_slave
Testing replication:
Tungsten provides built in scripts to test replication:
cookbook/test_cluster
prove cookbook/test_cluster
Other tests:
1.) Get information about replication:
2.) Detailed replication information using cookbook/trepctl command:
Replication Status:
Stop Replication:
Start Replication:
Try [mysql@master01 tungsten-replicator-2.1.0-343]$ cookbook/trepctl help for a lot more options.
