Documentation
1. Initial configuration
Create a service user for the execution service, create data directory and assign ownership.
sudo adduser --system --no-create-home --group execution
sudo mkdir -p /var/lib/besu
sudo chown -R execution:execution /var/lib/besu
Install dependencies.
sudo apt install -y openjdk-21-jdk libjemalloc-dev jq
2. Install Binaries
Downloading binaries is often faster and more convenient.
Building from source code can offer better compatibility and is more aligned with the spirit of FOSS (free open source software).
3. Setup and configure systemd
Create a systemd unit file to define your execution.service
configuration.
sudo nano /etc/systemd/system/execution.service
Paste the following configuration into the file.

To exit and save, press Ctrl
+ X
, then Y
, then Enter
.
Run the following to enable auto-start at boot time.
sudo systemctl daemon-reload
sudo systemctl enable execution
Finally, start your execution layer client and check it's status.
sudo systemctl start execution
sudo systemctl status execution
Press Ctrl
+ C
to exit the status.
4. Helpful execution client commands
sudo journalctl -fu execution | ccze
A properly functioning Besu execution client will indicate "Fork-Choice-Updates". For example,
2022-03-19 04:09:36.315+00:00 | vert.x-worker-thread-0 | INFO | EngineForkchoiceUpdated | Consensus fork-choice-update: head: 0xcd2a_8b32..., finalized: 0xfa22_1142...
2022-03-19 04:09:48.328+00:00 | vert.x-worker-thread-0 | INFO | EngineForkchoiceUpdated | Consensus fork-choice-update: head: 0xff1a_f12a..., finalized: 0xfa22_1142...
Now that your execution client is configured and started, proceed to the next step on setting up your consensus client.
If you're checking the logs and see any warnings or errors, please be patient as these will normally resolve once both your execution and consensus clients are fully synced to the Ethereum network.
