初始化

以下命令在各个节点执行 安装 docker 环境并启动 docker

yum install -y yum-utils device-mapper-persistent-data lvm2
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum makecache fast
yum -y install docker-ce
systemctl start docker
systemctl enable docker

下载镜像

docker pull registry.cn-hangzhou.aliyuncs.com/truechain_space/truechain_image:latest

更改镜像 tag 为 etrue

docker tag registry.cn-hangzhou.aliyuncs.com/truechain_space/truechain_image getrue

配置文件

在 node01 上建立目录，并建立几个初始化脚本

1

mdiir -p /opt/truechain

并建立一个传世快初始化配置文件

cd /opt/truechain
touch gensis.json

为了方便操作，我们把初始化做成一个脚本名为 init_gensis.sh 内容如下

1

docker run -v $PWD:/truechain-engineering-code -v $PWD/data:/truechain-engineering-code/data -it etrue --datadir /truechain-engineering-code/data init /truechain-engineering-code/genesis.json

赋予可执行权限

1

chmod a+x /opt/truechain/init_gensis.sh

在/opt/truechain 执行初始化

./init_gensis.sh

执行之后会生成出现如下日志

[root@www truechain]# ./init_gensis.sh

记录下 publickey，并用以下命令查看 privatekey

1

cat data/getrue/bftkey

并记录下 privatekey，删除目录下的 data 文件，再次执行初始化 init_gensis.sh 脚本，生成一对 publickey 和 privatekey ，按照方法生成 4 对 key，并填入 gensis.json 文件，最终的 gensis.json 文件格式如下

之后再创建启动委员会的脚本 start_work.sh，内容如下

1

docker run -v $PWD:/truechain-engineering-code -p 30303:30303 -p 10080:10080 -p 8545:8545 -it  etrue  --datadir /truechain-engineering-code/data  --bftkeyhex "4eed8ce61acc1c55e7f8fb608bc2bfef7f6cdbd40313c6ccd16de04362195e43" --election --bftip "0.0.0.0" --bftport 10080 --port 30303 --networkid 10 --rpc --rpcaddr 127.0.0.1 --rpcport 8545 --rpcapi "db,etrue,net,web3,personal,admin,miner"  --verbosity 1 console

清理掉 data 目录

1

rm -rf /opt/truechain/data

至此，配置文件及脚本已修改完毕，把整个 truechain 文件夹传到其他 3 个机器 ###配置节点配置

scp -r /opt/truechain/ root@172.16.66.11:/opt
scp -r /opt/truechain/ root@172.16.66.16:/opt
scp -r /opt/truechain/ root@172.16.66.17:/opt

复制之后，修改 node02.node03,node04 节点的 start_work.sh 文件，修改 bftkeyhex 为对应的 privatekey.。 node02 为第 2 对 key 的 privatekey node03 为第 3 对 key 的 privatekey node04 为第 4 对 key 的 privatekey 再各个节点先执行初始化脚，再执行委员会脚本

cd  /opt/truechain
./init_gensis.sh
./start_work.sh

启动之后，可以看到如下提示，表示启动成功

[root@monitor truechain]# ./start_work.sh

在各个节点使用 admin.nodeInfo.enode 查看节点信息，如下

> admin.nodeInfo.enode
"enode://6ff04de8fbb85dc80f1604062057da6e90390e4f256691e79541eee57a8e3d004917c45bb3b1476258a28c9215c5c43feff8dc67ee3f5f91cbc2b3ec738715ac@[::]:30303"
>

记录下节点信息，修改后面的[::]为节点的实际 ip,并编辑成以下形式的命令

admin.addPeer("enode://9eec6aa38162cb94c87f62ebc5492c43ce6e8dd039e6dfc55be7521c9033c7bfb14be7889efaa22697ae2917ebb4ad0f65dc9033956606d23959e742c5c39295@172.16.66.10:30303")

admin.addPeer("enode://560831be3d76f2526e56680e4e573d4e1c4e02a2c6edf866e71857a67e03131b59dee8e724978162982b522468609b9dd6ddffa1b7693c459148f3a3265100c3@172.16.66.17:30303")

以上节点信息根据自己的实际情况修改，后面为节点的实际 ip，端口为 30303,复制修改好的信息，张贴到各个节点的终端，即可完成添加节点工作。效果如下
