Fix the Certificate Chain (Recommended) You must ensure your web server provides the full chain (Leaf + Intermediate + Root). Concatenate Certificates: If you have a separate your_domain.crt and DigiCertCA.crt, you must combine them into a single file. Correct Order: Your Domain Certificate must come first, followed by the Intermediate(s).
cat navitrack_co_tz.key DigiCertCA.crt > navitrack_co_tz_fullchain.crt
Update Web Server(nginx) Configuration:
Incase you want to set SSL certificates in Dspace 7(Digicert and others) but not letsencrypt certificate. This is bacuase Node.js does not trust the certificates presented by apache/nginx to resolve this you need to do this
Error: Using a Self-Signed SSL Certificate causes the Frontend to not be able to access the Backend
Steps:
1. openssl x509 -in myCAcert.crt -out <certname>.pem -outform PEM
To be able to access the Dspace Frontend using the domain name or IP address with default port 80 instead of 4000, we need to configure a reverse proxy. For the purpose and simplicity in this guide, we will use Nginx. But you na use othe engine such as Apache
Install Nginx on Ubuntu with the command:
sudo apt install nginx -y
Create a virtual host file:
The Raspberry Pi can do a lot, especially now that the new Raspberry Pi comes with wireless capabilities already on board. It can take the place of a ton of different (and more expensive) devices – including a router! If you turn your Raspberry Pi into a wireless access point, you can make it act as a router. It’s not the most powerful thing in the world, but it does work, and the project is a lot of fun.
We’re going to get into the command line a bit here, but this project isn’t really all that difficult. All we’re really doing is using Raspbian and installing a couple packages that give the Pi the ability to do router-like things like assign IP addresses to devices that connect to it.
Check out our complete guide to installing Raspbian for the details on this one. Then plug everything in and hop into the terminal and check for updates and ugrades:
sudo apt-get update
sudo apt-get upgrade
DSpace 7 is an open-source digital repository software system that is designed to help institutions manage and showcase their digital assets, including research papers, academic publications, datasets, multimedia content, and more. It is the latest major version of DSpace, which is widely used by universities, libraries, and other organizations to create digital repositories and archives.
DSpace 7 includes a robust search and discovery system with advanced filtering options, making it easier for users to find and access the content they need.
The Dspace backend installation requires packages that include:
Java JDK 11 or 17 (OpenJDK or Oracle JDK)
Here's an example of a simple bash script that can be used to perform some basic maintenance tasks on a Linux server:
#!/bin/bash
# Update package list and upgrade installed packages
apt-get update && apt-get upgrade -y
# Remove unnecessary packages and dependencies
apt-get autoremove -y
Here's an example of a simple bash script that can be used to backup a MySQL database:
#!/bin/bash
# Set the backup directory and file name
BACKUP_DIR="/path/to/backup/dir"
DATE=$(date +"%Y-%m-%d")
BACKUP_FILE="database-$DATE.sql"
Here's an example of a simple script that can be used to backup a PostgreSQL database using the pg_dump command:
#!/bin/bash
# Set the name of the database you want to backup
database=mydb
# Set the name of the backup file
backup_file=mydb_$(date +%Y%m%d).bak
