Bitshares见证人备用服务器节点教程

in #bitshares4 years ago (edited)
  1. 选用备用服务器,最好换一家服务器提供商和地点,安装见证人节点,这个过程就略掉;

  2. 同步区块:
    screen -S witness_node
    ./programs/witness_node/witness_node --replay-blockchain --rpc-endpoint=127.0.0.1:8090 #加上--replay-blockchain选项,可以降低内存

  3. 运行钱包,设置密码,解锁钱包
    screen -S cli_wallet
    .programs/cli_wallet/cli_wallet -s ws://127.0.0.1:8090
    new>>>set_password 123456
    locked >>> unlock 123456

  4. 创建sign秘钥对:

    suggest_brain_key
    {
    "brain_priv_key": "XXXXX XXXX XXXXX XXXX",
    "wif_priv_key": "5Kxxxxxxxxxxxxxxxxxxxxxxxxxxxxxkf2ure",
    "pub_key": "BTSxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxaerwr"
    }
    保存秘钥对,以供后面作为signing key使用;

  5. Ctrl+C, 重新运行witness_node(关闭和启动的时候多耐心等待)
    ./witness_node -s 104.200.28.117:61705 --rpc-endpoint=127.0.0.1:8090 --witness-id '"1.6.71"' --private-key '["pub_key", "wif_priv_key"]’
    #将1.671换成你的见证人序列号,pub_key和wif_priv_key分别换成第4步你创建的pub_key和wif_priv_key

  6. 运行钱包,解锁,导入sigin private key和active wif key
    screen -r cli_wallet
    .programs/cli_wallet/cli_wallet -s ws://127.0.0.1:8090
    unlocked >>> import_key “witness.yao” 5Kxxxxxxxxxxx3 true #witness.yao换成你自己的账号,5Kxxxxxxxxxxx3换称该账号的签名权限的signing key
    unlocked >>> import_key “witness.yao” 5Gxxxxxxxxxxx6 true #witness.yao换成你自己的账号,5Gxxxxxxxxxxx6换称该账号的活跃权限active key

  7. 更新见证人signing key
    update_witness “witness.yao” "https://bitsharestalk.org/index.php/topic,23628.0.html" "BTSxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxaerwr" true
    #将witness.yao换成你自己的账号,https://xxx换成你自己的url,没有可以填xxx,BTSxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxaerwr换成你第4步创建的pub_key

  8. 过几秒钟,在你主节点cli钱包查看你自己的见证人信息,检查你的signing_key是否更新:

get_witness “witness.yao” #将witness.yao换成你自己的见证人账号
{
[...]
"id": "1.6.71",
"signing_key": "BTSxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxaerwr",
[...]
}
或者进入http://cryptofresh.com/查看你自己的见证人信息,检查你的signing_key是否更新
,若signing_key更新了,同时出块正常,代表你成功了。

|9. 把你主节点和备用节点的signing key都保存下来,当你的当前出块节点出现问题的时候,你就可通过第7步更新成你的另一个节点的signing key,这样你就可以避免大量丢快。
P.S. 目前在研究见证人监控脚本,后面最好做到当出块节点出现故障的时候,自动切换到备用节点,希望多多交流。

赞!期待下一篇监测和自动切换备用节点,让 witness 更具有鲁棒性!^_^

感谢!^^
