How can I install Neo4j on my Ubuntu 18.04 system?

I’ve been diving into the world of graph databases recently and I keep hearing about Neo4j and how powerful it is for managing relationships between data. I’ve got an Ubuntu 18.04 machine and I’m really eager to get it up and running, but to be honest, I’ve strolled through their documentation, and I feel a bit lost.

I mean, I can handle the basics of Linux, but when it comes to installing software like Neo4j, I just want to make sure I’m not missing any crucial steps. I guess my main concern is whether there are any prerequisites I need to be aware of. Should I have Java installed or can I just download Neo4j and let it handle everything?

I’ve also seen a lot of YouTube tutorials, but most of them are either too fast-paced or assume I know a whole lot more than I do. It would really help if someone could break it down into simple steps. You know, the kind where I can follow along without pausing every two seconds to figure out what the person on screen is doing.

And then there’s the whole thing about the database being accessible. Do I need to tweak any settings after installation to get it to run, or is it good to go right after I finish the installation? Also, are there any common pitfalls I should watch out for?

I’m excited about using Neo4j, especially for some of the projects I’m planning, but honestly, the installation part is driving me a bit nuts. I’ve done my fair share of installs with other software, but this one feels like it might have a few more steps involved, and I really don’t want to mess anything up or end up with a half-installed version.

If anyone has a step-by-step guide or could share their experience with installing Neo4j on Ubuntu 18.04, I would really appreciate it. Even if you have tips or common troubleshooting advice, I’m all ears! Thanks in advance to anyone who can help me out with this.

    1. Installing Neo4j on Ubuntu 18.04


      Installing Neo4j on Ubuntu 18.04

      Installing Neo4j can seem tricky, but don’t worry! I’ll break it down into simple steps.

      1. Prerequisites

      You don’t need to have Java pre-installed. Neo4j comes bundled with the required Java version, so just downloading Neo4j is enough.

      2. Downloading Neo4j

      1. Open your terminal (you can find it in your applications).
      2. Run the following command to download the Neo4j package:
        wget https://neo4j.com/artifact.php?name=neo4j-community-4.4.8-unix.tar.gz
      3. Unpack the downloaded file:
        tar -xzf neo4j-community-4.4.8-unix.tar.gz
      4. Move into the extracted folder:
        cd neo4j-community-4.4.8

      3. Installing Neo4j

      To start Neo4j, just run the following command:

      bin/neo4j start

      4. Accessing the Database

      After you start Neo4j, you can access it through your web browser by going to http://localhost:7474. You should be prompted to set a username (default is neo4j) and a password. Remember this, as you’ll need it later!

      5. Tweaks and Common Pitfalls

      Usually, it works right out of the box! But here are a few things to keep in mind:

      • If you encounter any issues starting Neo4j, try checking the logs at logs/neo4j.log for error messages.
      • Make sure you allow Neo4j through your firewall if you plan to access it from another machine.

      6. Troubleshooting

      If you run into any problems:

      • Ensure you’re running the commands from the Neo4j installation directory.
      • If the installation fails, try running bin/neo4j stop and then restart it.

      That’s it! You’re ready to dive into using Neo4j. Take your time exploring, and don’t hesitate to check out the Neo4j community forums for more tips.



    2. Installing Neo4j on Ubuntu 18.04 is straightforward, especially if you follow a structured approach. First and foremost, you don’t need to install Java separately since Neo4j comes bundled with the necessary Java runtime. You can install Neo4j via the official APT repository. To do this, start by adding the Neo4j GPG key to your system: wget -O - https://debian.neo4j.com/neotechnology.gpg.key | sudo apt-key add -. Next, add the repository to your system’s package list using: echo "deb https://debian.neo4j.com/ $(lsb_release -cs) main" | sudo tee /etc/apt/sources.list.d/neo4j.list. After that, update your package manager with sudo apt-get update and install Neo4j with sudo apt-get install neo4j. This will set everything up for you without any additional configurations.

      Once the installation is complete, you can start the Neo4j service by running sudo systemctl start neo4j. By default, Neo4j listens on port 7474 for HTTP connections, so you will be able to access it through your browser at http://localhost:7474. The first time you log in, the default credentials are ‘neo4j’ for both username and password, and you’ll be prompted to change the password. It’s also advisable to check the logs if you encounter any issues: /var/log/neo4j/neo4j.log. Common pitfalls include not having the correct version of Ubuntu or conflicting services occupying the default ports, so ensure that nothing else is using port 7474 or 7687. Follow these steps carefully, and you’ll have Neo4j up and running in no time!
