docker下搭建三个节点

1 进入一个ubuntu容器后基础的准备

apt-get install python-software-properties
 apt-get install software-properties-common
 apt-get  install  vim

2安装solc

 add-apt-repository ppa:ethereum/ethereum
 apt-get update
 apt-get install solc

3 安装Geth客户端
有多种以太坊客户端，安装Go-ethereum输入以下命令：


 add-apt-repository -y ppa:ethereum/ethereum
 apt-get update
 apt-get install ethereum

4 开始创建节点，创建一个目录，


mkdir private-geth
cd private-geth
vim genesis.json

{
    "config": {
        "chainId": 12345,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
    "coinbase" : "0x0000000000000000000000000000000000000000",
    "difficulty" : "0x400",
    "extraData" : "0x123456",
    "gasLimit" : "0xffffffff",
    "nonce" : "0x0000000000000042",
    "mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "timestamp" : "0x00",
    "alloc": { }
}

初始化初始块，进入geth平台

root@f2b5cdfdc5ed:/private-geth#  geth --datadir ./data/00 init genesis.json

geth --identity "haha" --datadir ./data/00 --networkid 12345  --rpcapi "db,eth,net,web3"  --port 2220 --rpcport 3330 console


（geth --datadir "./" --nodiscover console 2>>geth.log）

然后查看该节点的信息

{ enode: "enode://3452dd408cd4f1fb160725388579f28f2b0552ed63d5291a1e2615f60329355c296f00f6c61ddd671c429017b3e5ec6eb31304d5552aec817faa506507dcdc32@[::]:2220", id: "3452dd408cd4f1fb160725388579f28f2b0552ed63d5291a1e2615f60329355c296f00f6c61ddd671c429017b3e5ec6eb31304d5552aec817faa506507dcdc32", ip: "::", listenAddr: "[::]:2220", name: "Geth/haha/v1.6.7-stable-ab5646c5/linux-amd64/go1.8.1", ports: { discovery: 2220, listener: 2220 },
  protocols: { eth: { difficulty: 4357056, genesis: "0x29a42341a89cace1a303a40ca106b875f0ea4113a6e0a39dbbc663e9dfb8fb3f", head: "0x5163295934480c8b167698157ebe7e378c33f7a6fab0e19412947f65ca455f1a", network: 12345 }
  }
}

查看ip

root@f2b5cdfdc5ed:/# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
273: eth0@if274: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default 
    link/ether 02:42:ac:12:00:04 brd ff:ff:ff:ff:ff:ff link-netnsid 0
    inet 172.18.0.4/16 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::42:acff:fe12:4/64 scope link 
       valid_lft forever preferred_lft forever

第二个容器

ucsmy@QKTEST21191:~$ docker run -it --name ubuntublock1 -p 80:80 ebcd9d4fca80
docker: Error response from daemon: driver failed programming external connectivity on endpoint ubuntublock1 (da48c27d902362bd4678531c148e58df7c361a6e4fc61416ab8b4d97b435281b): Bind for 0.0.0.0:80 failed: port is already allocated.
 ```
 ```
ucsmy@QKTEST21191:~$ docker run -it --name ubuntublock1 -p 82:82 ebcd9d4fca80
docker: Error response from daemon: Conflict. The name "/ubuntublock1" is already in use by container 8a76dface80ee116e383bbb486f06d4a2184029617f9be016bae95d7b174ed11. You have to remove (or rename) that container to be able to reuse that name..
See 'docker run --help'.
但是查看的时候容器还是已经存在了
ucsmy@QKTEST21191:~$ docker ps -a
CONTAINER ID        IMAGE                                                                                                                                      COMMAND                  CREATED              STATUS              PORTS                                                                    NAMES
8a76dface80e        ebcd9d4fca80                                                                                                                               "/bin/bash"              About a minute ago   Created                                                                                      ubuntublock1
f2b5cdfdc5ed        ebcd9d4fca80                                                                                                                               "/bin/bash"              22 hours ago         Up 22 hours         0.0.0.0:80->80/tcp                                                       ubuntublock

进入容器

docker attach ubuntublock1

开始搭建以太坊环境

root@03fb89fa98ec:/# apt-get install git
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package git

然后需要更新一下包

apt-get update

准备工作

apt-get install python-software-properties
 apt-get install software-properties-common
 apt-get  install  vim

安装geth

 add-apt-repository -y ppa:ethereum/ethereum
 apt-get update
 apt-get install ethereum
mkdir private-geth
cd private-geth
vim genesis.json

{
    "config": {
        "chainId": 12345,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
    "coinbase" : "0x0000000000000000000000000000000000000000",
    "difficulty" : "0x400",
    "extraData" : "0x123456",
    "gasLimit" : "0xffffffff",
    "nonce" : "0x0000000000000042",
    "mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
    "timestamp" : "0x00",
    "alloc": { }
}

初始化geth并且进入geth 

geth --datadir ./data/01 init genesis.json

geth --identity "haha" --datadir ./data/01 --networkid 12345  --rpcapi "db,eth,net,web3" --port 2221 --rpcport 3331 console

admin.addPeer("enode://3452dd408cd4f1fb160725388579f28f2b0552ed63d5291a1e2615f60329355c296f00f6c61ddd671c429017b3e5ec6eb31304d5552aec817faa506507dcdc32@172.18.0.4:2220")

节点连接成功以后自动同步区块信息。

第三个容器

:/private-geth# geth --datadir ./data/00 init genesis.json 

geth --identity "haha" --datadir ./data/00 --networkid 12345  --rpcapi "db,eth,net,web3" --port 2222 --rpcport 3332 console


admin.addPeer("enode://3452dd408cd4f1fb160725388579f28f2b0552ed63d5291a1e2615f60329355c296f00f6c61ddd671c429017b3e5ec6eb31304d5552aec817faa506507dcdc32@172.18.0.4:2220")
