The first blog in this series is to install neo4j - desktop version and few plugins which would help us to build an application. I am using Ubuntu 22.04.4 LTS.
STEP 1
- Go to https://neo4j.com/deployment-center/?desktop-gdb and download the Neo4j Desktop (AppImage)
- If you are a mac or windows user, you can try other options available
- You will have to fill these details to download the file
- Copy the neo4j desktop activation key to a text file, this will be used later
STEP 2
- Open your terminal go to the directory where you have downloaded the file and run the following command, this makes the downloaded file executable
chmod +x DOWLOADED_FILE_NAME
- To run the application stay in the same directory as your downloaded file and run the following command
./DOWLOADED_FILE_NAME
- Once you run the command you'll be able to see the application window, paste the key that you copied in software key text box
STEP 3
- Click on new project
- Click on add in the top right corner and click on Local DBMS if you want to host the DB locally or Remote Connection if you are using a managed service somewhere. I am going to have it locally.
STEP 4
- Add a DB Name and Password, I have set it as praveen_blog and neo4j@123 and click on the create option at the bottom. The default username would be neo4j
- Tadaaa your instance is up and running
STEP 5
There are few plugins like APOC and Graph Data Science Library - GDS which are really useful and we'll be using it in this blog series.
To install them click on praveen_blog and a small window will be opened to the right, in the plugins tab you'll see APOC and Graph Data Science Library, click on install for both of them
- Once they are installed you are good to go. Create your graphs using cypher query and enjoy.
In the fore-coming blogs we'll see how to load data into neo4j using python and build a light weight application for augmented generation also called as RAG.
Hope this helps... See you !!!
