ETH 2.0主网节点搭建不质押教程(geth+prysum)
系统配置:
cpu: 8核
内存: 16G及以上
系统盘: 60G
数据盘: 1T及以上
系统: centos 7 (64位)
带宽: 独享 100M
- ETH 浏览器: https://etherscan.io/
1.下载geth
wget https://gethstore.blob.core.windows.net/builds/geth-linux-amd64-1.11.6-ea9e62ca.tar.gz
tar zxf geth-linux-amd64-1.11.6-ea9e62ca.tar.gz
cd geth-linux-amd64-1.11.6-ea9e62ca
cp geth /usr/bin/
geth version
Geth Version: 1.11.6-stable Git Commit: ea9e62ca3db5c33aa7438ebf39c189afd53c6bf8 Git Commit Date: 20230420 Architecture: amd64 Go Version: go1.20.3 Operating System: linux GOPATH= GOROOT=
- 我用1.12.0有各种奇怪的报错,用这个1.11.6这个版本没有问题,可以正常同步.
2.安装Prysum
mkdir -p /data/prysm && cd /data/prysm
curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh --output prysm.sh && chmod +x prysm.sh
3.生成JWT令牌
./prysm.sh beacon-chain generate-auth-secret
4.启动geth
mkdir /data/eth_data
vim /lib/systemd/system/geth.service
[Unit]
Description=goerli chain
StartLimitIntervalSec=500
StartLimitBurst=5
[Service]
Restart=on-failure
RestartSec=5s
ExecStart=/usr/bin/geth --mainnet --cache 4096 --http --http.addr "0.0.0.0" --http.api eth,net,engine,admin --syncmode snap --gcmode archive --authrpc.addr localhost --authrpc.port 8551 --authrpc.vhosts localhost --authrpc.jwtsecret /data/prysm/jwt.hex --datadir /data/eth_data --allow-insecure-unlock --db.engine pebble --txlookuplimit 48958
Type=simple
User=root
KillSignal=SIGINT
TimeoutStopSec=12000
[Install]
WantedBy=multi-user.target
保存后,执行:
systemctl daemon-reload
systemctl start geth.service
systemctl enable geth.service
5.启动prysm
vim /lib/systemd/system/prysm.service
[Unit]
Description=prysm mainnet
After=network-online.target
Wants=network-online.target
[Service]
User=root
WorkingDirectory=/data/prysm
ExecStart=/data/prysm/prysm.sh beacon-chain --mainnet --checkpoint-sync-url=https://sync.invis.tools --genesis-beacon-api-url=https://sync.invis.tools --execution-endpoint=http://localhost:8551 --jwt-secret=/data/prysm/jwt.hex --datadir=/data/prysm/data --p2p-max-peers 100 --build-block-parallel=true --accept-terms-of-use=true
Restart=always
RestartSec=3
LimitNOFILE=65535
[Install]
WantedBy=multi-user.target
保存后执行:
systemctl daemon-reload
systemctl start prysm.service
systemctl enable prysm.service
6.查看日志
journalctl -u prysm.service -ef -n 50
journalctl -u geth.service -ef -n 50
7.防火墙设置
- 阻止8545/tcp, 3500/tcp, 8551/tcp, 4000/tcp
- 允许13000/tcp, 12000/udp, 30303/tcp+udp
