To test the port on which MySQL is running

#sudo netstat -nlp | grep -i mysql

It will give output like

unix  2      [ ACC ]     STREAM     LISTENING     133857 4959/mysqld         /var/lib/mysql/mysql.sock

The above MySQL is running on 3306 port

My Linux version is Red Hat 5 so i download from http://dev.mysql.com/downloads/mysql/ the following RPMs

MySQL-server-5.5.25a-1.rhel5.i386.rpm
MySQL-client-5.5.25a-1.rhel5.x86_64.rpm

Depending upon the time when you are reading this tutorial the file names would change , but the process would be the same

Upload the files to the server is this is some remote machine , i used WinSCP to do this

Install theb MySQL

#sudo rpm -i MySQL-server-5.5.25a-1.rhel5.i386.rpm

It will ask for sudo password

Proceed with the instructions and complete the process. Remember to note down root password if you set any

#sudo rpm -i MySQL-client-5.5.25a-1.rhel5.x86_64.rpm

Hadoop Client


Hadoop Client 
 
Client machines have Hadoop installed with all the cluster settings, but are neither a Namenode or a Datanode. The difference is that client machine don’t have any hadoop services started.  That’s why we are able to run commands to interact with hdfs if we mount using fuse.

Besides this Clients can have components like Hive / Sqoop running from where users can interact with the cluster
