echo "export PATH=/usr/local/cmake-3.15.2/bin:$PATH" >> /etc/profile source /etc/profile cmake -version [root@192 ~]# cmake -version cmake version 3.15.2 CMake suite maintained and supported by Kitware (kitware.com/cmake).###4.安装go语言
wget https://storage.googleapis.com/golang/go1.13.2.linux-amd64.tar.gz tar -C /usr/local -zxzf go1.13.2.linux-amd64.tar.gz echo "export GOROOT=/usr/local/go" >> /etc/profile echo "export PATH=/usr/local/go/bin:$PATH" >> /etc/profile source /etc/profile [root@192 ~]# go version go version go1.13.2 linux/amd64###5.克隆并编译go-ethereum项目
cd /usr/local git clone https://github.com/ethereum/go-ethereum.git cd go-ethereum/ make all echo "export PATH=$PATH:/usr/local/go-ethereum/build/bin" >> /etc/profile source /etc/profile [root@192 ~]# geth version Geth Version: 1.9.12-unstable Git Commit: 556888c4a971d4fd02be15f09cba7a65c5c0d930 Git Commit Date: 20200303 Architecture: amd64 Protocol Versions: [65 64 63] Go Version: go1.13.2 Operating System: linux GOPATH= GOROOT=/usr/local/go###6.开启网络时间同步
systemctl enable ntpd systemctl start ntpd###7.创建geth工作目录
mkdir -pv /test/chain vim /test/genesis.json [root@192 ~]# cat /test/genesis.json { "config": { "chainId": 666, "homesteadBlock": 0, "eip150Block": 0, "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000", "eip155Block": 0, "eip158Block": 0, "byzantiumBlock": 0, "constantinopleBlock": 0, "petersburgBlock": 0, "istanbulBlock": 0, "ethash": {} }, "nonce": "0x0", "timestamp": "0x5ddf8f3e", "extraData": "0x0000000000000000000000000000000000000000000000000000000000000000", "gasLimit": "0x47b760", "difficulty": "0x00002", "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "coinbase": "0x0000000000000000000000000000000000000000", "alloc": { "0x1e82968C4624880FD1E8e818421841E6DB8D1Fa4" : {"balance" : "30000000000000000000"} }, "number": "0x0", "gasUsed": "0x0", "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000" }###8.启动geth命令
[root@localhost test]# geth --port '30303' --datadir "./chain" --nodiscover console 2>>eth_output.log Welcome to the Geth JavaScript console! instance: Geth/v1.9.12-unstable-556888c4-20200303/linux-amd64/go1.13.2 coinbase: 0x60b50043de183a439c96891416c003c46623f528 at block: 109 (Mon Mar 09 2020 16:18:37 GMT+0800 (CST)) datadir: /test/chain modules: admin:1.0 debug:1.0 eth:1.0 ethash:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0 >
###9.账户的添加和查看（在启动私有链后的Geth javascript console中操作）
> web3.eth.accounts []创建帐户的方式有两种，第一种创建帐户时直接初始化密码
> web3.personal.newAccount("123456") "0x60b50043de183a439c96891416c003c46623f528"其中返回的0x60b50043de183a439c96891416c003c46623f528是帐户，123456是帐户的密码
第二种方法是先创建账户，然后输入密码
> web3.personal.newAccount() Passphrase: Repeat passphrase: "0xdb66c9c37efabab160f5453d27676e7930153eec"
这时我们再查看帐户，能够看到刚才创建的两个帐户已经存在了
> web3.eth.accounts ["0x60b50043de183a439c96891416c003c46623f528", "0xdb66c9c37efabab160f5453d27676e7930153eec"] ###10.开始和停止
执行以下命令：
> miner.start(1)
执行以后，通过刚才查看日志的方法tail -f eth_output.log,能够看到类似下面的日志，说明程序已经在进行.
