• Install Java, Tomcat 8, Postgresql 10, Ant, Maven and git
• Configure Tomcat 8 server and
• Create dspace database in Postgresql 10

• Ubuntu Linux OS 18.04 and
• gedit text editor

However you may use any other text editor of your choice.

• You need an internet connection to install the necessary packages and
• You should be familiar with basic Linux commands.

• i3 processor or above
• 100GB hard disk or more
• 4GB RAM or above and
• A network facility

Please download and extract the file before practicing.

And I will use the same file to copy-paste the commands during the demonstration.

Shortcut to paste on the terminal is Shift, Ctrl and V keys.

Ensure that you have root permissions to run the commands.

sudo adduser dspace

To do so, type the command sudo adduser dspace and press Enter.

admin password

So, type the admin password and press Enter.

The process of creating a new user has begun.

Type password as dupass

Here we have to set the password for the user dspace.

I will set the password as dupass.

You can give any password of your choice.

We have now successfully created the user dspace.

sudo adduser dspace sudo

By doing this, the user dspace will have full control of the system.

In the terminal, type sudo adduser dspace sudo

sudo su - dspace

Type sudo su - dspace

If prompted, type the password of user dspace to login.

sudo apt-get update

To do this, type sudo apt-get update

If prompted, type the password of user dspace to proceed further.

sudo dpkg --configure -a

sudo dpkg --configure -a

sudo apt-get install openjdk-8-jdk -y

To do so, type the following command in the terminal.

The installation may take some time depending upon your internet speed.

java -version

To do so, type java -version

0_242 in the openjdk version is the release number, which may be different in your case.

sudo apt-get remove openjdk-11-jre-headless

• If the JDK version other than 8 is installed, then remove it.
• For example, if JDK version 11 is installed then type the command as shown.

Switch to the terminal.

sudo apt-get install git -y

So let us install the git tool.

To do so, type the command as shown here.

sudo apt-get install maven -y

To do so, type the command as shown here.

sudo apt-get install ant ant-optional -y

To do so, type the command as shown.

sudo apt-get install tomcat8 -y

To install Tomcat, type the command as shown here.

sudo gedit /etc/tomcat8/policy.d/05dspace.policy

This will provide all Java security permissions to DSpace.

Type the command as shown, to open a new policy file in gedit text editor.

You can do this in your editor, as well.

grant codeBase "file:/home/dspace/-" {

permission java.security.AllPermission;

};

grant codeBase "file:/tmp/-" {

permission java.security.AllPermission;

};

Type DSpace security policy as shown here.

You can copy-paste this piece of code from the Code File, as demonstrated here.

sudo chown root.tomcat8 /etc/tomcat8/policy.d/05dspace.policy

sudo adduser tomcat8 dspace

To do so, type the command as shown here.

sudo adduser dspace tomcat8

To do so, type the command as shown here.

sudo service tomcat8 restart

To do so, type the command as shown here.

sudo apt-get install postgresql-10 postgresql-contrib postgresql-contrib-10 libpg-java -y

Type the command as shown in the terminal to install postgresql.

To do that, we have to change peer, md5 and ident to trust.

sudo sed -i 's/peer/trust/' /etc/postgresql/10/main/pg_hba.conf

sudo sed -i 's/md5/trust/' /etc/postgresql/10/main/pg_hba.conf

sudo sed -i 's/ident/trust/' /etc/postgresql/10/main/pg_hba.conf

sudo service postgresql restart

To do so, type the command as shown here.

createuser -U postgres -d -A -P dspace

Type the password as dbuserpass

I will set the password as dbuserpass.

You can give any password of your choice.

We have successfully created the user dspace in postgresql.

sudo su - postgres

To do so type the command as shown.

createdb -E UNICODE dspace

To do so, type the following command.

psql -U postgres -d dspace

ALTER DATABASE dspace OWNER TO dspace;

To do so, type the following command.

GRANT ALL PRIVILEGES ON DATABASE dspace TO dspace;

CREATE EXTENSION pgcrypto;

We will now add crypto extension to DSpace database.

So type the command as shown here.

To do so, we will require root permissions.

Enter the root user password if prompted.

sudo echo "host dspace dspace 127.0.0.1/32 md5" >> /etc/postgresql/10/main/pg_hba.conf

sudo service postgresql restart

To do so, type the command as shown here.

sudo gedit $HOME/.bashrc

To do so, type sudo gedit $HOME/.bashrc

You can open this file in any text editor of your choice.

bashrc file opens in the text editor.

umask 002

Type umask 002

umask 002 sets default directory permissions to 775 and default file permissions to 664.

sudo reboot

To do so, type sudo reboot in the terminal.

This will restart your computer.

Let us summarize.

• Install Java, Tomcat8, Postgresql 10, Ant, Maven, and git
• Configure Tomcat8 server and
• Create dspace database in Postgresql 10
