搭建以太坊私链_系统运维

概述1.下载安装git,因为需要下载克隆代码(方便). 命令:yum -y install git 2.下载安装go语言环境,因为需要使用go语言编译geth. 命令1:wget https://dl.google.com/go/go1.12.1.linux-amd64.tar.gz 命令2:tar -xzf go1.12.1.linux-amd64.tar.gz 命令3:vi /etc/profil

1.下载安装git,因为需要下载克隆代码(方便).
命令:yum -y install git
2.下载安装go语言环境,因为需要使用go语言编译geth.
命令1:wget https://dl.Google.com/go/go1.12.1.linux-amd64.tar.gz
命令2:tar -xzf go1.12.1.linux-amd64.tar.gz
命令3:vi /etc/profile 添加环境变量:export PATH=$PATH:/usr/local/software/go/go/bin
命令4:source /etc/profile
3.下载安装geth.
命令1:git clone https://github.com/ethereum/go-ethereum.git
命令2:cd go-ethereum
命令3:git checkout release/1.8
命令4:make geth,执行此命令时报错(不报错直接略过)exec: "gcc": executable file not found in $PATH,是由于没有gcc引起的,直接安装即可,命令:yum -y install gcc,然后再执行make geth.
命令5:vi /etc/profile 添加环境变量:export PATH=$PATH:/usr/local/software/go/go/bin
命令6:source /etc/profile 添加环境变量:export PATH=$PATH:/usr/local/software/go_project/go-ethereum/build/bin
4.创建私链.
1.创建genesis.Json文件,以初始化创世区块.
内容:{
"config": {
"chainID": 999,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x20000",
"exTradata" : "0xe998bfe58b87e79a84e7a781e993be2d31",
"gaslimit" : "0x2fefd8",
"nonce" : "0x0000000000000042",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00",
"alloc" : {}
}
2.执行命令:geth init ./genesis.Json --datadir "./private_chain_data"

5.启动私链.切勿直接使用geth命令,因为存在默认配置,这样会直接启动公网节点,会同步巨大的公网区块.
