How to Install DSpace on Ubuntu Server Latest

DSpace is a digital repository software system used to capture, store, index, preserve, and redistribute a wide range of digital content. In this tutorial, we will be installing DSpace on Ubuntu server latest.

Prerequisites

Before starting, ensure that your system meets the following requirements:

Ubuntu Server Latest
Java Version 8 or higher
PostgreSQL

Step 1: Installing Java

Update your Ubuntu server with the following command:
```
sudo apt-get update
```
Install Java using the following command:
```
sudo apt-get install default-jdk
```
Verify the Java installation by running the following command:
```
java -version
```
You should see the Java version installed on your system.

Step 2: Installing PostgreSQL

Install PostgreSQL by running the following command:

sudo apt-get install postgresql postgresql-contrib

After the installation, create a new user for PostgreSQL with the following command:
```
sudo su postgres
createuser --interactive
```
Enter a name for the PostgreSQL user and select the options for the new user.
Create a new database for DSpace with the following command:
```
createdb dspace
```
Change the owner of the dspace database to the user that was created earlier:
```
ALTER USER <username> WITH CREATEDB;
```
Finally, exit the PostgreSQL command prompt by typing the following command:
```
\q
```

Step 3: Downloading and installing DSpace

Download the latest version of DSpace from the following link: https://github.com/DSpace/DSpace/releases
Extract the downloaded file to a directory of your choice.
Open the installation directory and run the following command:
```
mvn package
```
This will build the necessary files needed for the installation.
Copy the configuration files from the dspace/config directory to the dspace/config/local directory:

cp dspace/config/* dspace/config/local

Edit the dspace/config/local/dspace.cfg file and update the configuration settings for your system.
- Change the db.name property to dspace.
- Change the db.username and db.password properties to the PostgreSQL username and password created earlier.
Create a new user for DSpace with the following command:
```
sudo adduser dspace
```
Change the ownership of the DSpace installation directory to the dspace user:
```
sudo chown -R dspace:dspace /path/to/dspace
```
Switch to the dspace user with the following command:
```
sudo su dspace
```
Initialize the DSpace database with the following command:
```
/path/to/dspace/bin/dspace database initialize
```
Install the DSpace software with the following command:

/path/to/dspace/bin/dspace install

Start the DSpace software with the following command:

/path/to/dspace/bin/dspace start

You can verify that DSpace is running by visiting the IP address of your server in a web browser.

Congratulations! You have successfully installed DSpace on Ubuntu server latest.
