Choose a VPS from a genuine provider. For running Koha and Dspace for a medium size library, minimum configuration shall be
RAM - 2 GB (4 GB is prefereble), SSD- 80 GB
(Approx. amount will be Rs.15000/year)
After purchasing the VPS do the following steps. They will provide us the root user name and password.
I. Open the terminal window of your local machine. Connect to the Server with ssh command.
eg: user@koha:$ ssh root@yourcloudip
II. create a different user with administrative privilege; (It is not advisable to use root user for software installation)
root@yourcloudip:$ adduser <newuser>
Some details will ask. Enter the details if you wish to give, otherwise skip the questions for default. Enter a strong Password with Uppercase, Special characters and Numerals
root@yourcloudip:$ add user <newuser> sudo
III. Setting time and location
root@yourcloudip:$ dpkg-reconfigure tzdata
The time zone will ask and select appropriately.
IV. Reboot the system
root@yourcloudip:$ reboot
Again Connect the server from your local machine with ssh command. Instead of using root@yourcloudip Connect with <newuser>@yourcloudip. Provide the newly created password of the user account.
V. Firewall Enabling:
1. To check whether the firewall is active, run the command
<newuser>@localhost:$ sudo ufw status verbose
The system will show firewall is inactive
2. Then first enable ssh connection
<newuser>@localhost:$ sudo ufw allow ssh
3. Then enable ufw
<newuser>@localhost:$ sudo ufw enable
4. Then open http port and https port
<newuser>@localhost:$ sudo ufw allow http
<newuser>@localhost:$ sudo ufw allow https
5.If you want to open port 8080 for running Dspace
Open 8080 port also
<newuser>@localhost:$ sudo ufw allow 8080/tcp
Similarly we can open any port
6. To see the open ports
<newuser>@localhost:$ sudo ufw status numbered
7.To disable the port
Find out the number in the above command
<newuser>@localhost:$ sudo ufw delete 3
VI. Update and Upgrade Operating system
<newuser>@localhost:$ sudo apt-get update
<newuser>@localhost:$ sudo apt-get upgrade
