EOS 整个链停止,重新强制引导启动

BP节点全部停止,各节点重新启动后,无法正常出块

最近因为非技术原因,导致测试链所有BP节点都停止了。
由于producer_plugin中的安全检查,导致BP节点启动后,一直处于start_block_result::waiting
导致整个链网络瘫痪。

强制引导启动

先准备一台非目前BP节点所在的机器做强制引导节点。然后把目前出块账户的 2/3 +1 个BP账号都配置到此节点。
并把目前其他的BP节点都关闭pkill nodeos

修改强制引导节点的链程序,绕过安全检查

https://github.com/EOSIO/eos/blob/3c553db73864ea19458512b4669cf9942dc59f57/plugins/producer_plugin/producer_plugin.cpp#L1350
将下面代码注释掉,并重新编译链程序

if (_pending_block_mode == pending_block_mode::speculating) {
      auto head_block_age = now - chain.head_block_time();
      if (head_block_age > fc::seconds(5))
         return start_block_result::waiting;
   }

修改BP节点的配置为同步节点的配置

先将其余BP节点的config,改为同步节点的配置,也就是把强制引导节点的p2p-peer-address加到各BP节点的config,并把各BP节点的producer-namesignature-provider都注释掉。

强制启动引导节点

添加-e,强制启动出块

nodeos -e

此时强制出块节点应该已出块。

启动各BP节点

将其余BP节点分别启动,此时开始同步区块,等到追上强制出块节点高度。

迁移BP账号

关闭强制出块节点,把BP账号从config里面每注释掉一部分,就把对应的BP节点停止,并修改config,把对应的BP账号放开。此时重新启动强制出块节点和新迁移BP的节点,现在强制出块节点除去注释掉的部分出块账号。其余BP账号出块正常,且能从新迁移BP节点同步对应的出块BP账号的出块。新迁移的BP节点,出块也正常。
依次类推,迁移其余BP节点账号,等其余BP节点都出块正常后,及此次强制引导启动链网络结束。

备注

能出现全部节点停止的情况,基本都是特殊公链-“私链”,所以具有大部分BP的掌控权,我们先只针对此情景提出修复方案。

EOS 同步Mongo,各表数据解释

使用场景

由于需要对链上数据进行大量自定义得查询,一般来说还是通过部署同步节点,然后使用mongo插件将链上数据同步到Mongo进行使用更直接和方便。(虽然有其他得替代方案比如(Hyperion-History-API)(history-tools),测试下来,mongo更直接些,如果以后有其他方案更新,我们在做文章跟进,此处我们只讨论同步mongo得方案)

mongo 插件配置

必须开启以下配置,才能获取以下讨论中谈及得数据

  • mongodb-store-block-states = true
  • mongodb-store-blocks = true
  • mongodb-store-transactions = true
  • mongodb-store-transaction-traces = true
  • mongodb-store-action-traces = true

Mongo 数据表介绍

使用官方得mongo插件同步后,库数据表如下

  • account_controls
  • accounts
  • action_traces
  • block_states
  • blocks
  • pub_keys
  • transaction_traces
  • transactions

// 稍后补充

附加

action_traces表默认没有"trx_id"得索引,如果想根据"trx_id"查询得话,可以自行添加索引,不然会很慢。

db.action_traces.getIndexes()
db.action_traces.createIndex({"trx_id":1, "background":true})
