Evmos验证人节点搭建

跑了Evmos验证人几天，由于刚上线不久，官方还比较混乱，节点搭建的官方教程也不完整，所以写了一份目前比较完整的节点搭建攻略

节点配置:

CPU 8核+
内存 10GB+
硬盘 500GB+（节点很费硬盘)
CPU和内存也尽量高点，不然容易丢块

安装GO 1.17

sudo rm -rf /usr/local/go;
curl https://dl.google.com/go/go1.17.linux-amd64.tar.gz | sudo tar -C/usr/local -zxvf - ;
cat <<'EOF' >>$HOME/.profile
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export GO111MODULE=on
export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin
EOF
source $HOME/.profile

#安装完成后运行以下命令查看版本

1	go version

安装其他必要的环境

1 2	sudo apt-get update -y && sudo apt-get upgrade -y; sudo apt-get install build-essential -y;

下载源代码并编译

1
2
3

git clone https://github.com/tharsis/evmos
cd evmos && git checkout tags/v1.1.1 
make install

安装完成后可以运行 evmosd version –long 检查是否安装成功

evmosd version --long

name: evmos
server_name: evmosd
version: 1.1.1

初始节点

1	evmosd init <moniker> --chain-id=evmos_9001-1

*``改成你要设置的名字

创建key

1	evmosd keys add <your key name>

*` `改成你要设置的钱包名

下载genesis.json

1	curl https://archive.evmos.dev/genesis/genesis.json > ~/.evmosd/config/genesis.json

检查Genesis文件是否正确

1 2	cd ~/.evmosd/config echo "0d25dd7abf7325e518519ca2289775f611c0beaf1a2caf3a6b080e66168c2d6e genesis.json" \| sha256sum -c

添加Persistent Peer

修改 ./evmosd/config/config.toml 文件，找到persistent_peers, 添加下面的peers

persistent_peers = "[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26756,588cedb70fa1d98c14a2f2c1456bfa41e1a156a8@evmos-sentry.mercury-nodes.net:29539,[email protected]:26756,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:45556,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656,[email protected]:26656"

运行节点(使用Cosmovisor)

下载并设置Cosmovisor

git clone https://github.com/cosmos/cosmos-sdk
cd cosmos-sdk
git checkout v0.44.6
make cosmovisor
cp cosmovisor/cosmovisor $GOPATH/bin/cosmovisor
cd $HOME
mkdir -p ~/.evmosd
mkdir -p ~/.evmosd/cosmovisor
mkdir -p ~/.evmosd/cosmovisor/genesis
mkdir -p ~/.evmosd/cosmovisor/genesis/bin
mkdir -p ~/.evmosd/cosmovisor/upgrades
echo "# Setup Cosmovisor" >> ~/.profile
echo "export DAEMON_NAME=evmosd" >> ~/.profile
echo "export DAEMON_HOME=$HOME/.evmosd" >> ~/.profile
echo 'export PATH="$DAEMON_HOME/cosmovisor/current/bin:$PATH"' >> ~/.profile
source ~/.profile
cp $GOPATH/bin/evmosd ~/.evmosd/cosmovisor/genesis/bin

创建背后运行服务

sudo tee /etc/systemd/system/evmosd.service > /dev/null <<EOF  
[Unit]
Description=Evmos Daemon
After=network-online.target

[Service]
User=$USER
ExecStart=$(which cosmovisor) start
Restart=always
RestartSec=3
LimitNOFILE=infinity

Environment="DAEMON_HOME=$HOME/.evmosd"
Environment="DAEMON_NAME=evmosd"
Environment="DAEMON_ALLOW_DOWNLOAD_BINARIES=false"
Environment="DAEMON_RESTART_AFTER_UPGRADE=true"

[Install]
WantedBy=multi-user.target
EOF

创建好后，更新，开启节点服务

1
2
3

sudo -S systemctl daemon-reload
sudo -S systemctl enable evmosd
sudo -S systemctl start evmosd

上面的命令运行好后，你的节点就开启了

用下面命令查看服务：

查看服务状态

1	systemctl status evmosd

查看服务日志

1	journalctl -u evmosd -f

上线验证人

等你的节点同步好后，可以运行下面命令上线你的验证人:

evmosd tx staking create-validator \
  --amount=1000000000000aevmos \
  --pubkey=$(evmosd tendermint show-validator) \
  --moniker="EvmosWhale" \
  --chain-id=<chain_id> \
  --commission-rate="0.05" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --min-self-delegation="1000000" \
  --gas="auto" \
  --gas-prices="0.025aevmos" \
  --from=<key_name>

注：要进入前150名后，你的验证人才会激活
