Fedora 29 安装Neo4j失败求助：repo加载失败且找不到安装包

Hey there, let's get your Neo4j up and running on Fedora 29 smoothly. The errors you're facing—failed loading '/etc/yum.repos.d/neo4j.repo' and No match for argument: neo4j—are caused by either a misconfigured repository file or incorrect permissions on it. Here's a step-by-step solution:

Step 1: Remove the Problematic Repo File #

First, let's get rid of the faulty repo file you created earlier to avoid conflicts:

sudo rm /etc/yum.repos.d/neo4j.repo

Step 2: Create a Correct Neo4j Repository Configuration #

Fedora 29 is compatible with RHEL 7-based package sources, so we'll use the official Neo4j repo tailored for this ecosystem. Open a new repo file with your preferred editor (we'll use nano here):

sudo nano /etc/yum.repos.d/neo4j.repo

Paste the following configuration into the file:

[neo4j]
name=Neo4j Yum Repository
baseurl=https://yum.neo4j.com/stable
enabled=1
gpgcheck=1
gpgkey=https://debian.neo4j.com/neotechnology.gpg.key

Save and exit the editor (for nano, press Ctrl+O, then Enter, then Ctrl+X).

Step 3: Set Proper Permissions for the Repo File #

Yum/Dnf skips repo files with overly permissive settings, which is likely why your original file failed to load. Set the standard, secure permissions:

sudo chmod 644 /etc/yum.repos.d/neo4j.repo
sudo chown root:root /etc/yum.repos.d/neo4j.repo

This sets read/write access for the root user and read-only access for all other users—exactly what Yum expects.

Step 4: Refresh Package Cache and Install Neo4j #

First, update the package metadata to recognize the new repo:

sudo dnf makecache

Then install Neo4j (you can use yum instead of dnf if you prefer, as they're compatible on Fedora 29):

sudo dnf install neo4j

Step 5: Verify Installation and Start the Service #

Once installation completes, start the Neo4j service and set it to run on boot:

sudo systemctl start neo4j
sudo systemctl enable neo4j

Check if the service is running properly:

sudo systemctl status neo4j

You should see an "active (running)" status if everything went well.

Note on Neo4j Versions #

Fedora 29 uses an older version of Java (OpenJDK 11 is the default), which is compatible with Neo4j 4.x series. If you need a specific version (e.g., 4.4 LTS), modify the baseurl in the repo file to https://yum.neo4j.com/4.4 instead of stable. Neo4j 5.x requires Java 17+, which isn't readily available on Fedora 29, so stick to 4.x for best compatibility.
