节点接入安顺官方网络

全节点接入区块链网络需要自行维护一个节点。

全节点可以以共识节点或同步节点两种方式接入，接入正式环境前请联系官方工作人员开放节点接入白名单。

安装环境

• Ubuntu 16或18

• CentOS 7

部署方式和配置设置

1. 编译节点可执行文件geth，并将编译好的geth文件copy到节点目录,示例中节点目录为/data/install

cp geth /data/install

2. 新建node文件夹，配置genesis.json, static-nodes.json 和nodekey文件

注意将nodekey中的keystore替换为当前要配置的节点keystore

$ cd /data/install
$ mkdir node && cd node
$ vi genesis.json

3. 初始化节点

$ cd /data/install 
# $pass 为keystore钱包文件的密码
$ export NODE_PASS=$pass
$ ./geth init node/genesis.json --datadir node
INFO [05-18|00:13:45.204] Maximum peer count                       ETH=50 LES=0 total=50

4. 配置启动脚本start.sh文件

作为共识节点参与网络所需启动脚本如下：

$ cd /data/install 
$ vi start.sh
#!/bin/bash
echo "input node pass"
read -s pass
export NODE_PASS=$pass

port=30300
rpcport=8545
node="node"

miner=0x2D3913c12ACa0E4A2278f829Fb78A682123c0125
echo "$node and miner is $miner, rpc port $rpcport, p2p port $port"

nohup ./geth --mine --miner.threads 1 \
--miner.etherbase=$miner \
--identity=$node \
--maxpeers=100 \
--syncmode full \
--allow-insecure-unlock \
--datadir $node \
--networkid 2088 \
--txlookuplimit 0 \
--txpool.pricelimit 1000000000 \
--http.corsdomain "*" \
--http.api admin,eth,debug,miner,net,txpool,personal,web3 \
--http --http.addr 0.0.0.0 --http.port $rpcport --http.vhosts "*" \
--port $port \
--verbosity 5 \
--nodiscover >> $node/node.log 2>&1 &

sleep 3s;
ps -ef|grep geth|grep mine|grep -v grep;

同步节点参与网络所需配置如下：

$ cd /data/install 
$ vi start.sh
#!/bin/bash
echo "input node pass"
read -s pass
export NODE_PASS=$pass

port=30300
rpcport=8545
node="node"

echo " rpc port $rpcport, p2p port $port"

nohup ./geth --identity=$node \
--maxpeers=100 \
--syncmode full \
--allow-insecure-unlock \
--datadir $node \
--networkid 2088 \
--txlookuplimit 0 \
--txpool.pricelimit 1000000000 \
--http.corsdomain "*" \
--http.api admin,eth,debug,net,txpool,personal,web3 \
--http --http.addr 0.0.0.0 --http.port $rpcport --http.vhosts "*" \
--port $port \
--verbosity 5 \
--nodiscover >> $node/node.log 2>&1 &

sleep 3s;
ps -ef|grep geth|grep -v grep;

5. 执行start.sh脚本，输入钱包文件密码，启动节点

$ chmod +x start.sh
$ ./start.sh
input node pass

node and miner is 0x2D3913c12ACa0E4A2278f829Fb78A682123c0125, rpc port 8545, p2p port 30300
