ETH 2.0 节点分为执行客户端、共识客户端、验证软件，同步数据节点无论是快照同步还是完整存档，都需要同步启动执行客户端和共识客户端。
- 安装配置执行客户端
Nethermind
sudo apt-get update && sudo apt-get install libsnappy-dev libc6-dev libc6 unzip
wget https://github.com/NethermindEth/nethermind/releases/download/1.14.5/nethermind-linux-amd64-1.14.5-380bf9c-20221029.zip
unzip nethermind-linux-amd64-1.14.5-380bf9c-20221029.zip -d nethermind
添加下面配置到nethermind/configs/mainnet.cfg
"JsonRpc": {
"Enabled": true,
"Timeout": 20000,
"Host": "127.0.0.1",
"Port": 8545,
"EnabledModules": ["Eth", "Subscribe", "Trace", "TxPool", "Web3", "Personal", "Proof", "Net", "Parity", "Health"],
"EnginePort": 8551,
"EngineHost": "127.0.0.1",
"JwtSecretFile": "keystore/jwt-secret"
},
启动Nethermind
cd nethermind
./Nethermind.Launcher
# 选择具体配置，或者
./Nethermind.Runner --config mainnet
- 安装配置共识客户端
Prysm
mkdir prysm && cd prysm
curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh --output prysm.sh && chmod +x prysm.sh
./prysm.sh beacon-chain --datadir ./data --execution-endpoint=http://localhost:8551 --jwt-secret=~/nethermind/keystore/jwt-secret --checkpoint-sync-url=https://beaconstate.ethstaker.cc
--genesis-beacon-api-url=https://beaconstate.ethstaker.cc
# 如果要做验证者，需要添加参数 --suggested-fee-recipient=0x01234567722E6b0000012BFEBf6177F1D2e9758D9
- 验证检查点正确性
在https://beaconstate.ethstaker.cc/上确认slot编号对应的State root. 如果一致，表明所使用的检查点是正确的。
curl -s http://127.0.0.1:3500/eth/v1/beacon/headers/finalized | jq .'data.header.message'
