Download tomcat setup or if you have copy it using WinSCP tool
Setup link :-
http://redrockdigimark.com/apachemirror/tomcat/tomcat-7/v7.0.82/bin/apache-tomcat-7.0.82.tar.gz
Create a folder and copy setup. Or choose your preferred location where you want to install.
# mkdir setup
# chmod 777 setup/
# cd /setup
# ls
# chmod 777 apache-tomcat-6.0.44.tar.gz

Create a shared folder on one server and map this to multiple servers.
Uses nfs, autofs tools.
This works on most Linux flavors.
Scenario:-
Server1 – Create folder /SharedFolder, share this over network, and map this to Server2, Server3.
Steps:-
Server1## mkdir /sharedfolder
Server1## vi /etc/exports
/sharedfolder Server2(rw,no_root_squash) Server3(rw,no_root_squash)
Server1## chkconfig –levels 345 nfs on
Server1## service nfs restart
Server1## exportfs
Server2## vi /etc/auto.master
#Comment all the lines with # as first character’s and add these lines
/- /etc/auto.direct
+auto.master
Server2## vi /etc/auto.direct
/mnt/sharedfolder -fstype=nfs,rw,soft,intr Server1:/sharedfolder
Server2## chkconfig –levels 345 autofs on
Server2## service autofs restart
[comment- network folder is mounted to /mnt/sharedfolder directory. No need to create sharedfolder directory under /mnt on server2##, it will get created automatically from network mount. ]
Server3## Proceed the same like Server2## to mount it.
mount -t nfs 112.168.171.231:/New/mount /New/mount
# mount 162.168.112.8:/usr/eams/sharedsync/interfaces /usr/eams/sharedsync/interfaces
Update your system:
sudo yum update
Install and Start MariaDBPermalink
sudo yum install mariadb-server
sudo systemctl enable mariadb
sudo systemctl start mariadb
/usr/bin/mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.
Set root password? [Y/n] Passw0rd
Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n]
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n]
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n]
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!
Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.
Reload privilege tables now? [Y/n] y
... Success!
Cleaning up...
All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.
Thanks for using MariaDB!

However, if you don’t ever want to just blindly have the kernel updated, you can add the following to your /etc/yum.conf file:
exclude=kernel*
Or, if you insist on using a vanilla configuration file and control everything via the CLI, use
#yum –xclude=kernel* update
Both of these methods will eliminate the kernel from being updated or even included in the potential update listing.
sudo yum update --skip-broken
Attach the installation CD and on allotting HDD space check it manual partitioning.
Follow the configuration steps.
Select the partition scheme as per your requirement.
Give the mount point size in that box and desired capacity.
It will create the partitions like that above.
Next follow the default values you need to install.
