如何连接到EOS Jungle TestNet

如何连接到EOS Jungle TestNet

• 指定genesis-json来修改chain_id(参考https://blog.csdn.net/jc0803kevin/article/details/105440296)

• 修改config.ini文件

  添加plugin相关语句
  添加p2p-peer-address列表

• 启动时清空已有的区块链数据信息 --delete-all-blocks(可选)

EOS Jungle Testnet 测试链

PS: 20181124 jungle 升级到 jungle2.0，
原 jungle1.0 将不会再被支持，https://jungle.bloks.io 上的数据已经切换到 jungle2.0

启动nodeos

第一次启动

nodeos \
--genesis-json /root/genesis.json \
--delete-all-blocks \
--plugin eosio::producer_plugin \
--plugin eosio::producer_api_plugin \
--plugin eosio::chain_api_plugin \
--plugin eosio::http_plugin \
--plugin eosio::history_plugin \
--plugin eosio::history_api_plugin \
--filter-on="*" \
--access-control-allow-origin='*' \
--contracts-console \
--http-validate-host=false \
--verbose-http-errors >> nodeos.log 2>&1 &

再次启动

再次启动的时候不需要添加这两个参数
–genesis-json /root/genesis.json 指定创世节点
–delete-all-blocks 删除所有的区块

nodeos \
--plugin eosio::producer_plugin \
--plugin eosio::producer_api_plugin \
--plugin eosio::chain_api_plugin \
--plugin eosio::http_plugin \
--plugin eosio::history_plugin \
--plugin eosio::history_api_plugin \
--filter-on="*" \
--access-control-allow-origin='*' \
--contracts-console \
--http-validate-host=false \
--verbose-http-errors >> nodeos.log 2>&1 &

确认链接到测试网络

只要chain_id和jungle Testnet 上面一致，那说明成功链接到jungle Testnet。

[root@test-work2 ~]# cleos get info

}

head_block_num 为 1： 说明没有同步区块，

需要配置对应测试网络的种子节点。

然后配置到config.ini对应的位置，重新启动nodeos,查看日志即可查看到出块信息。
