Package starcluster :: Package plugins :: Module mysql :: Class MysqlCluster

Class MysqlCluster


This plugin configures a mysql cluster on StarCluster
Author: Marc Resnick

Steps for mysql-cluster to work:
1. mkdir -p /var/lib/mysql-cluster/backup
2. chown -R mysql:mysql /var/lib/mysql-cluster/
3. generate ndb-mgmd for master
4. generate my.cnf for data nodes
5. /etc/init.d/mysql-ndb-mgm restart on master
6. pkill -9 mysql on data nodes
7. /etc/init.d/mysql start on data nodes
8. /etc/init.d/mysql-ndb restart on data nodes

Correction to above, do this:
1. define plugin section in config named mysql
2. start cluster mysql (will fail)
3. starcluster runplugin mysql mysql
