Erigon - Successor to OpenEthereum, Erigon is an implementation of Ethereum (aka "Ethereum client"), on the efficiency frontier, written in Go.
Overview
Official Links
1. Initial configuration
Create a service user for the execution service, create data directory and assign ownership.
Copy sudo adduser --system --no-create-home --group execution
sudo mkdir -p /var/lib/erigon
sudo chown -R execution:execution /var/lib/erigon
Install dependencies.
Copy sudo apt install curl libsnappy-dev libc6-dev jq libc6 unzip -y
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).
Option 1 - Download binariesRun the following to automatically download the latest linux release, un-tar and cleanup.
Copy RELEASE_URL = "https://api.github.com/repos/ledgerwatch/erigon/releases/latest"
BINARIES_URL = "$( curl -s $RELEASE_URL | jq -r ".assets[] | select(.name) | .browser_download_url" | grep linux_amd64 )"
echo Downloading URL: $BINARIES_URL
cd $HOME
wget -O erigon.tar.gz $BINARIES_URL
tar -xzvf erigon.tar.gz -C $HOME
rm erigon.tar.gz
Install the binaries.
Copy sudo mv $HOME /erigon /usr/local/bin/erigon
Option 2 - Build from source codeInstall Go dependencies. Latest version available here .
Copy wget -O go.tar.gz https://go.dev/dl/go1.20.5.linux-amd64.tar.gz
sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go.tar.gz
echo export PATH= $PATH :/usr/local/go/bin >> $HOME /.bashrc
source $HOME /.bashrc
Verify Go is properly installed by checking the version and cleanup files.
Copy go version
rm go.tar.gz
Install build dependencies.
Copy sudo apt-get update
sudo apt install build-essential git
Build the binary.
Copy mkdir -p ~/git
cd ~/git
git clone https://github.com/ledgerwatch/erigon.git
cd erigon
git fetch --tags
# Get latest tag name
latestTag = $( git describe --tags ` git rev-list --tags --max-count=1 ` )
# Checkout latest tag
git checkout $latestTag
make erigon
Install the binary.
Copy sudo cp $HOME /git/erigon/build/bin/erigon /usr/local/bin
3. Setup and configure systemd
Create a systemd unit file to define your execution.service
configuration.
Copy sudo nano /etc/systemd/system/execution.service
Paste the following configuration into the file.
Copy [Unit]
Description = Erigon Execution Layer Client service for Mainnet
Wants = network-online.target
After = network-online.target
Documentation = https://www.coincashew.com
[Service]
Type = simple
User = execution
Group = execution
Restart = on-failure
RestartSec = 3
KillSignal = SIGINT
TimeoutStopSec = 900
ExecStart = /usr/local/bin/erigon \
--datadir /var/lib/erigon \
--chain mainnet \
--port 30303 \
--torrent.port 42069 \
--maxpeers 50 \
--private.api.addr 127.0.0.1:9099 \
--authrpc.port 8551 \
--metrics \
--pprof \
--prune htc \
--prune.r.before=11052984 \
--authrpc.jwtsecret=/secrets/jwtsecret
[Install]
WantedBy = multi-user.target
To exit and save, press Ctrl
+ X
, then Y
, then Enter
.
Run the following to enable auto-start at boot time.
Copy sudo systemctl daemon-reload
sudo systemctl enable execution
Finally, start your execution layer client and check it's status.
Copy sudo systemctl start execution
sudo systemctl status execution
Press Ctrl
+ C
to exit the status.
4. Helpful execution client commands
View Logs Stop Start View Status Reset Database
Copy sudo journalctl -fu execution | ccze
A properly functioning Erigon execution client will indicate "Handling new payload". For example,
Copy erigon[3]: [INFO] [09-29|03:36:24.689] [NewPayload] Handling new payload height=19999 hash=0xea060...2846a907ceb4
erigon[3]: [INFO] [09-29|03:36:25.278] [updateForkchoice] Fork choice update: flushing in-memory state (built by previous newPayload)
erigon[3]: [INFO] [09-29|03:36:25.280] RPC Daemon notified of new headers from=19998 to=19999 hash=0xeeed..710b597 header sending=13.32µs log sending=290ns
erigon[3]: [INFO] [09-29|03:36:25.280] head updated hash=0xea06098ad5e...5e5f43 number=20000
Copy sudo systemctl stop execution
Copy sudo systemctl start execution
Copy sudo systemctl status execution
Common reasons to reset the database can include:
Recovering from a corrupted database due to power outage or hardware failure
Re-syncing to reduce disk space usage
Upgrading to a new storage format
Copy sudo systemctl stop execution
sudo rm -rf /var/lib/erigon/*
sudo systemctl restart execution
Time to re-sync the execution client can take a few hours up to a day.
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.
