In the following guide we will go to implement an IPSec VPN Site to Site with the objetive of interconnect two location through the Internet using two routers with Cisco IOS. This little guide is limited to describe the procedure to carry on the explained objetive, for that reason I won´t go to explain anything theoric in detail.
In the following scenery we can look that we have two offices which we want to interconnect through the Internet by an Tunnel Ipsec:
MySQL Cluster is a clustering solution for MySQL Database Engine which allow the clustering of databases in a no-share environment, therefore each solution component has its own disk space and memory to operate. In its more basic implementation MySQL Cluster should be accompained with MySQL Standard and one in memory storage engine called NDB Cluster. In this practice guide I pretend show you the implementation process more basic possible in a GNU/Linux environment.
Before go forward to the guide we should have clear some concepts:
MySQL Node: Operating System with a MySQL Standard Server.
Data Node: Operating System with a NDBCluster Storage Engine.
Management Node: Operating System with a service for node administration and supervision.
