本文主要是介绍区块链 fisco bcos 2.72 在多机器上部署多个docker节点 ubuntu，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
一、安装
1. 安装依赖
安装curl、openssl:
sudo apt-get update
sudo apt install -y curl openssl
2. 安装docker:
(1)安装docker
# 更新包索引
sudo apt-get update
# 安装基础依赖库
sudo apt-get install \apt-transport-https \ca-certificates \curl \gnupg-agent \software-properties-common
# 添加Docker官方GPG key
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
# 添加docker仓库
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
# 更新包索引
sudo apt-get update
# 安装Docker
sudo apt-get install docker-ce docker-ce-cli containerd.io(2)加入docker用户组
sudo groupadd docker
sudo usermod -aG docker $USER(3)安装Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
3. 下载安装脚本
## 创建操作目录
cd ~ && mkdir -p fisco && cd fisco## 下载脚本
curl -#LO https://github.com/FISCO-BCOS/FISCO-BCOS/releases/download/v2.7.2/build_chain.sh && chmod u+x build_chain.sh注解
如果因为网络问题导致长时间无法下载build_chain.sh脚本:
- 多试几次
- 也可以换成 curl -#LO https://gitee.com/FISCO-BCOS/FISCO-BCOS/raw/master/tools/build_chain.sh && chmod u+x build_chain.sh
4. 搭建单群组4节点区块链
（1）查看ip
每个机器一个节点
| machine name | ip |
| fiscobcos_docker1 | 192.168.64.137 |
| fiscobcos_docker2 | 192.168.64.138 |
| fiscobcos_docker3 | 192.168.64.139 |
| fiscobcos_docker4 | 192.168.64.140 |
(2)生成区块链所有节点的配置
以下所有都在fiscobcos_docker1（192.168.64.137）机器操作
将节点信息写入到ipconf文件中
# 这里所有区块链节点均属于agencyA，并仅启动了群组1
# (注: 下面的ip信息需要根据真实的机器IP填写)
cat >> ipconf << EOF
192.168.64.137 agencyA 1
192.168.64.138 agencyA 1
192.168.64.139 agencyA 1
192.168.64.140 agencyA 1
EOF
（3）基于配置文件生成区块链节点配置
在fisco目录下执行下面的指令，生成一条单群组4节点的区块链。
请确保机器的30300，20200，8545端口没有被占用，也可以通过-p参数指定其他端口。
bash build_chain.sh -d -f ipconf -p 30300,20200,8545- -d表示以docker方式启动
- -f表示读取ipconf配置文件
- -p表示指定端口号
命令执行成功会输出All completed。
如果执行出错，请检查nodes/build.log文件中的错误信息。
shijianfeng@ubuntu:~/fisco$ bash build_chain.sh -d -f ipconf -p 30300,20200,8545

Group:1 has 4 nodes
==============================================================
[INFO] Docker tag : latest
[INFO] IP List File : ipconf
[INFO] Start Port : 30300 20200 8545
[INFO] Server IP : 192.168.64.137 192.168.64.138 192.168.64.139 192.168.64.140
[INFO] Output Dir : /home/shijianfeng/fisco/nodes
[INFO] CA Path : /home/shijianfeng/fisco/nodes/cert/
==============================================================
[INFO] Execute the download_console.sh script in directory named by IP to get FISCO-BCOS console.
e.g. bash /home/shijianfeng/fisco/nodes/192.168.64.137/download_console.sh -f
==============================================================
[INFO] All completed. Files in /home/shijianfeng/fisco/nodes
至此，成功生成了多机4节点配置，每台机器的区块链节点配置均位于nodes文件夹下，如下：
shijianfeng@ubuntu:~/fisco$ ls nodes/
192.168.64.137 192.168.64.138 192.168.64.139 192.168.64.140 cert
（4）拷贝区块链节点配置
生成区块链节点配置后，需要将每个节点配置拷贝到对应机器上，可通过scp命令执行拷贝，具体如下：
# 为每台机器创建操作目录~/fisco
# (注: 这里使用shijianfeng用户进行操作; 实际操作时，可使用自己的账户进行类似操作, IP也需要替换成自己的机器IP)
ssh shijianfeng@192.168.64.138 "mkdir -p ~/fisco"
ssh shijianfeng@192.168.64.139 "mkdir -p ~/fisco"
ssh shijianfeng@192.168.64.140 "mkdir -p ~/fisco"# 拷贝节点配置
# 拷贝节点配置到192.168.64.137的~/fisco路径
scp -r nodes/192.168.64.137/ shijianfeng@192.168.64.137:~/fisco/192.168.64.137# 拷贝节点配置到192.168.64.138的~/fisco路径
scp -r nodes/192.168.64.138/ shijianfeng@192.168.64.138:~/fisco/192.168.64.138# 拷贝节点配置到192.168.64.139的~/fisco路径
scp -r nodes/192.168.64.139/ shijianfeng@192.168.64.139:~/fisco/192.168.64.139# 拷贝节点配置到192.168.64.140的~/fisco路径
scp -r nodes/192.168.64.140/ shijianfeng@192.168.64.138:~/fisco/192.168.64.140如果报错scp ssh 22: connection refused

5. 启动区块链节点
区块链节点配置拷贝成功后，需要启动所有节点，可通过某台机器发起ssh操作远程启动区块链节点，也可登录上所有物理机后，在对应的物理机上启动区块链节点。
本文采用直接登录机器启动区块链节点
执行nodes/node_ip/start_all.sh
# (注: 这里使用fisco用户进行操作; 实际操作时，可使用自己的账户进行类似操作, IP也需要替换成自己的机器IP)
# 登录192.168.64.137并启动区块链节点
$ ssh fisco@192.168.64.137
$ bash ~/fisco/192.168.64.137/start_all.sh# 登录192.168.64.138并启动区块链节点
$ ssh fisco@192.168.64.138
$ bash ~/fisco/192.168.64.138/start_all.sh# 登录192.168.64.139并启动区块链节点
$ ssh fisco@192.168.64.139
$ bash ~/fisco/192.168.64.139/start_all.sh# 登录192.168.64.140并启动区块链节点
$ ssh fisco@192.168.64.140
$ bash ~/fisco/192.168.64.140/start_all.sh
启动时，会查找本地是否存在FISCO-BCOS对应版本的节点镜像，不存在则从docker hub下载。
$ bash nodes/127.0.0.1/start_all.sh
try to start node0
try to start node1
try to start node2
try to start node3

6. 查看节点
登录每台机器，执行如下命令判断是否启动成功：
（1）检查容器状态是否正常
$ docker ps -a | egrep fiscobcos8df0d79bf764 fiscoorg/fiscobcos:v2.7.2 "/usr/local/bin/fisc…" 5 minutes ago Up 5 minutes rootfisconodes127.0.0.1node2
2bb7b89e2a46 fiscoorg/fiscobcos:v2.7.2 "/usr/local/bin/fisc…" 5 minutes ago Up 5 minutes rootfisconodes127.0.0.1node1
e66fe7c68d3a fiscoorg/fiscobcos:v2.7.2 "/usr/local/bin/fisc…" 5 minutes ago Up 5 minutes rootfisconodes127.0.0.1node0
c27dcaa0adfb fiscoorg/fiscobcos:v2.7.2 "/usr/local/bin/fisc…" 5 minutes ago Up 5 minutes rootfisconodes127.0.0.1node3
容器状态为UP时，说明节点正常启动。
（2）检查是否所有节点都连接上
可以通过检查日志来确认节点的p2p连接数目、共识是否正常。
查看节点node0连接的节点数
tail -f ~/fisco/*/node0/log/* |grep -i connected
正常情况会不停地输出连接信息，从输出可以看出node0与另外3个节点有连接。
info|2019-01-21 17:30:58.316769| [P2P][Service] heartBeat,connected count=3
info|2019-01-21 17:31:08.316922| [P2P][Service] heartBeat,connected count=3
info|2019-01-21 17:31:18.317105| [P2P][Service] heartBeat,connected count=3
（3）检查共识是否正常
登录每台机器，进入操作目录，执行如下命令判断节点共识是否正常：
tail -f ~/fisco/*/node0/log/* |grep -i +++
正常情况会不停输出++++Generating seal，表示共识正常。
info|2020-12-22 17:24:43.729402|[g:1][CONSENSUS][SEALER]++++++++++++++++ Generating seal on,blkNum=1,tx=0,nodeIdx=1,hash=2e133146...
info|2020-12-22 17:24:47.740603|[g:1][CONSENSUS][SEALER]++++++++++++++++ Generating seal on,blkNum=1,tx=0,nodeIdx=1,hash=eb199760...到此docker环境已经部署完成，可通过控制台对其发起交易。
二、安装控制台、部署合约、发送交易
以下所有都在fiscobcos_docker1（192.168.64.137）机器操作
第一步. 准备依赖
- 安装java （推荐使用java 14）.
# ubuntu系统安装java
sudo apt install -y default-jdk我安装的java sdk 1.8
第二步. 下载并配置控制台
（1）下载控制台
# 创建操作目录
mkdir -p ~/fisco && cd ~/fiscocurl -#LO https://github.com/FISCO-BCOS/console/releases/download/v2.7.1/download_console.sh# 若因为网络问题导致长时间无法下载，请尝试以下命令：
curl -#LO https://gitee.com/FISCO-BCOS/console/raw/master/tools/download_console.shbash download_console.sh
（2）配置控制台: 拷贝SDK证书
这里选择从fiscobcos_docker1（192.168.64.137）拷贝SDK证书，具体操作如下：
# 从192.168.64.137拷贝证书到conf目录下
scp 192.168.64.137:~/fisco/192.168.64.137/sdk/* ~/fisco/console/conf
（3）配置控制台: 修改控制台配置
# 拷贝控制台配置
cp -n ~/fisco/console/conf/config-example.toml ~/fisco/console/conf/config.toml# 修改控制台连接信息(操作中，控制台连接的IP信息请根据实际情况填写)
sed -i 's/peers=\["127.0.0.1:20200", "127.0.0.1:20201"\]/peers=["192.168.64.137:20200", "192.168.64.138:20200", "192.168.64.139:20200", "192.168.64.140:20200"]/g' ~/fisco/console/conf/config.toml
第三步. 启动并使用控制台
启动控制台
bash ~/fisco/console/start.sh控制台启动成功后，会输出如下信息：
=============================================================================================
Welcome to FISCO BCOS console(2.7.0)!
Type 'help' or 'h' for help. Type 'quit' or 'q' to quit console.________ ______ ______ ______ ______ _______ ______ ______ ______

第四步、使用控制台发送交易
# 获取节点信息
[group:1]> getNodeVersion
ClientVersion{version='2.6.0',supportedVersion='2.6.0',chainId='1',buildTime='20200819 15:47:59',buildType='Darwin/appleclang/RelWithDebInfo',gitBranch='HEAD',gitCommitHash='e4a5ef2ef64d1943fccc4ebc61467a91779fb1c0'
}# 得到其它节点
