Installation of DSpace 6.3 on Ubuntu 18.04.1 LTS

72 comments

Hi, friends, I could install  Dspace 6.3 (latest) on Ubuntu 18.04.1 LTS successfully after fixing bugs which occurred in the installation process. Here I provide a note for the installation by which you can try. (NB: I highly recommend you to install Ubuntu 18.04.1 minimal or Ubuntu 16.04  or any other lite weight Ubuntu flavors for the fast performance) 

Installation of prerequisite applications
  • Java Development Kit (JDK)
  • PostgreSQL Database
  • DSpace Software
  • Apache Ant (Pure Java Build Tool)
  • Apache Maven (Apache Build Automation Tool for Java Projects)
  • Apache Tomcat (Web Server for hosting Dspace)
Open  Applications > Accessories > Terminal and execute the following commands.

sudo apt update && sudo apt upgrade -y

sudo apt-get install openjdk-8-jdk postgresql ant maven


Choose OpenJDK-8 as default for that run this command

sudo update-alternatives --config java 

Create the database user

sudo -i -u postgres

createuser -U postgres -d -A -P dspace


Enter the password for new role: [Enter a password e.g. dspace]

Shall the new role be allowed to create more new roles? (y/n) n

[Enter n and press enter button]

Type exit

Allow the database user (dspace) to connect to the database

[If the following command not open, check the postgresql version number and apply in the command]

sudo nano /etc/postgresql/10/main/pg_hba.conf

Add this line to the configuration file at the end:

local all dspace md5

save and close the file

Restart PostgreSQL :

sudo su
/etc/init.d/postgresql restart


Create Dspace user

sudo useradd -m dspace
sudo passwd dspace [enter a password for the new user dspace]
sudo mkdir /dspace
sudo chown dspace /dspace


Create the PostgreSQL 'dspace' database

sudo -u dspace createdb -U dspace -E UNICODE dspace

save and close  the file.

Login to the database as a superuser, and enable the pgcrypto

extension on this database

sudo su postgres
psql --username=postgres dspace -c "CREATE EXTENSION pgcrypto;"


exit

sudo /etc/init.d/postgresql restart

Create a directory to build, give all permissions and Download DSpace into /build directory

sudo mkdir /build && sudo chmod -R 777 /build && cd /build && sudo wget https://github.com/DSpace/DSpace/releases/download/dspace-6.3/dspace-6.3-src-release.tar.gz

You can find the latest updated of Dspace 6.x version from this page and copy the link to download the latest version.

Extracting Dspace package

sudo tar -zxf dspace-6.3-src-release.tar.gz

Open the following file and remove a piece of lines.

sudo nano /build/dspace-6.3-src-release/dspace-api/pom.xml

Remove the following group of codes. Carefully check the lines in the file.

<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.4</version>
<executions><execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
</plugin>


Save and close the file.

Installation of DSpace

Enter into the Dspace package folder and apply the following commands one by one.

cd /build/dspace-6.3-src-release
sudo mvn -U package
cd dspace/target/dspace-installer && sudo ant fresh_install


Installation of Tomcat

Download the and extract the Tomcat package,

cd /opt && sudo wget http://apachemirror.wuchna.com/tomcat/tomcat-9/v9.0.37/bin/apache-tomcat-9.0.37.tar.gz

Or you can visit the Tomcat website and download the latest package.

Extract Tomcat package

sudo tar xvzf apache-tomcat-9.0.37.tar.gz

Rename folder "apache-tomcat-9.0.37" to "tomcat" and Delete the Tomcat archive file from /opt folder

sudo mv apache-tomcat-9.0.37 tomcat && sudo rm apache-tomcat-9.0.37.tar.gz

Open the following file,

sudo nano /etc/profile
Setup environment variables

Environment variables to find JAVA.

Add following lines at the bottom of the file,

export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export CATALINA_HOME=/opt/tomcat

Copy Dspace web apps files to Tomcat folder

sudo cp -r /dspace/webapps/* /opt/tomcat/webapps

Running Tomcat automatically

You can set up to start the Tomcat server start automatically at the time of system turn on.

Open the following file in a Terminal,

sudo nano  /etc/init.d/tomcat

Add following lines in the file,

#!/bin/bash
### BEGIN INIT INFO
# Provides:        tomcat8
# Required-Start:  $network
# Required-Stop:   $network
# Default-Start:   2 3 4 5
# Default-Stop:    0 1 6
# Short-Description: Start/Stop Tomcat server
### END INIT INFO

PATH=/sbin:/bin:/usr/sbin:/usr/bin

start() {
 sh /opt/tomcat/bin/startup.sh
}

stop() {
 sh /opt/tomcat/bin/shutdown.sh
}

case $1 in
  start|stop) $1;;
  restart) stop; start;;
  *) echo "Run as $0 <start|stop|restart>"; exit 1;;
esac


save and close the file.

Apply the following commands too;

sudo chmod +x /etc/init.d/tomcat && sudo update-rc.d tomcat defaults

Restart Tomcat server and Postgresql database

sudo service tomcat start && sudo service tomcat stop && sudo service tomcat restart && sudo /etc/init.d/postgresql restart && sudo /etc/init.d/tomcat restart

Make an initial administrator account (an e-person) in DSpace:

Apply following command in a terminal,

sudo /dspace/bin/dspace create-administrator

It will ask to enter the email address for the user login.
Enter an email address (e.g. dspace@localhost).
Enter First name and surname (e.g. dspace)
Enter a password.

Delete the build folder

sudo rm -rf /build

Open DSpace in your browser
DSpace has two interfaces; xmlui and jspui. You can load either one Dspace interface in a browser.

http://localhost:8080/xmlui
http://localhost:8080/jspui

    1. For changing port visit

      http://dspacegeek.blogspot.com/2016/07/change-dspace-port-number-8080-to-8081.html


      and if your dspace is installed locally. there is no need of assigning Let's Encrypt. Let’s Encrypt identifies the server administrator by public key.

    1. may be the version of java will be openjdk-11.. you may pls change it. by executing following command.

      update-alternatives --config java

      and select openjdk-8 as default.probably 2nd one will be openjdk-8 then re-run maven. will be successful.

  9. How do I access ip from dspace directly the xmlui or jspui page opens without the need to define / xmlui or / jspui ...?
    example: ip_addrees opens the main page from xmlui or jspui not like ip_address / xmlui or ip_address / jspui

    ReplyDelete
    Replies
    1. Dear. Akbar. Xmlui and Jspui are the two interfaces of dspace for accessing dspace you have to choose either of them followed by ip adress. Otherwise It will only show the tomcat page showing which is working. So one of the interface must be used.

    2. Luis, just relax. I initially encountered the same error while I installed DSpace too. But a big thanks to Mahesh Palamuttath who bailed me out.
      To solve this problem you just need to follow this step.

      STEP 1.
      Execute the command below
      update-alternatives --config java

      STEP 2.
      Kindly select openjdk-8 as default

      The second one will be openjdk-8

      STEP 3.
      Then re-run maven using
      mvn -U package

      Your Build will become successful.

      Best regards.

  13. Hello! Thanks for the tutorial! I still have a problem, when I try to copy dspaces to tomcat this error appear:
    “cp: cannot stat 'dpace/webapps/*': No such file or directory”
    However when I move the asterisk everything seems to work fine (sudo cp -r /dspace/webapps/ /opt/tomcat/webapps), the only problem is that when I create the administrator this appear:
    "sudo: /dspace/bin/dspace: command not found"
    Do you know how can I fix this?

  20. hi Mahesh Palamuttath first of all thank you for sharing that installation of dspace. I've applied all the steps one by one and completed the installation succesfully. But I can't customise the home page. (for example: change the color) I've changed the head title in the file of messages_tr.xml in dspace/webapps/xmlui/i18n but not changed the home page it was the same. do I work in wrong place. or did I skip any step. thank you for all.

  38. Hello Mahesh,

  42. Thank you very much for your article. I did everything wright but When I try to open dspace in my browser , it says,Unable to connect

    Firefox can’t establish a connection to the server at localhost:8080.

    The site could be temporarily unavailable or too busy. Try again in a few moments.
    If you are unable to load any pages, check your computer’s network connection.
    If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

    How can I fix it? Thanks in advance.
