EOS 主网节点搭建,快照snapshots同步数据

下载编译安装EOS

# 我们以EOS-Mainnet仓库部署，（EOS-Mainnet是部署在目前EOS主网的版本，等于再次在EOSIO仓库测试过的版本，更稳定。）
git clone https://github.com/EOS-Mainnet/eos.git

# 切换分支, 目前稳定版本为mainnet-1.6.0
git checkout mainnet-1.6.0

# build
./eosio_build.sh
# install
sudo ./eosio_install.sh

# 完成之后查看版本
nodeos -v
mainnet-1.6.0

编辑配置文件

# linux下
vi ~/.local/share/eosio/nodeos/config/config.ini

# macos下
~/Library/Application\ Support/eosio/nodeos/data/

# 添加p2p-pper-address, 可以从下面的链接获得

编辑genesis.json

# 默认的genesis.json在 eos/build目录下, 相比默认的, 修改时间戳和key就好了
# 可以直接下载
wget https://eosnodes.privex.io/static/genesis.json

第一次启动

# 因为在config.ini里配置了plugin, 所以就不需要再指定plugin了
# 据说第一次启动需要指定genesis.json, 进到genesis.json所在目录执行以下命令

nodeos --genesis-json genesis.json

# 如果失败了可以删除以前的旧数据
rm  -rf ~/.local/share/eosio/nodeos/data/blocks/*
rm  -rf ~/.local/share/eosio/nodeos/data/state/* 

查看是否是连到主网

# 查看chain id是否是aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906
cleos get info

# 查看第191块block(也不知道为什么教程里都是这个, 估计是因为191块里转账memo的一段话)
cleos get block 191
“data”: {
“from”: “eosio”,
“to”: “b1”,
“quantity”: “10.0000 EOS”,
“memo”: “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it’s the only thing that ever has - eosacknowledgments.io”

从snapshots启动

# 进到data目录
cd ~/.local/share/eosio/nodeos/data
# 删除snapshots,state和blocks目录, 也就是把data目录下清空了
# 下载快照
wget $(wget --quiet "https://eosnode.tools/api/snapshots?limit=1" -O- | jq -r '.data[0].s3') -O snapshot.tar.gz
# 解压
tar xvzf snapshot.tar.gz
# 启动 (后面的名字需要换成当时下载的文件名)
nodeos --snapshot snapshots/snapshot-0260cc527fa835e8d9dcb44793e2bf58aa6ca6e67638de034042e29cff1ae40a.bin

退出nodeos再启动

# 查到进程
ps -ef | grep nodeos
ubuntu   12745     1 27 02:43 ?        01:21:48 nodeos
ubuntu   13324 13277  0 07:41 pts/1    00:00:00 grep --color=auto nodeos

# 保存并退出 (注意是-2, 之前用-9强制退出之后就启动不了了)
kill -2 12745

# 再启动, 直接nodeos命令就可以了
nodeos
