搭建一个私有的EOS集群 - 2

多节点的搭建

上一篇 搭建一个私有的EOS集群 搭建了一个单节点的私链，本文将继续介绍多节点的私链搭建。

一台服务器上搭建的多节点

启动keosd和创建钱包

1、启动keosd程序

keosd的配置文件可以参考上一篇文章。

1
keosd -d wallet/data --config-dir wallet/config &

2、创建钱包

[root@dbl14195 eos]# cleos --wallet-url http://127.0.0.1:8899  wallet create --to-console
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5Juu3fMoX6wK3rV4kMeZToXitspmWLHw3k1zpx7BJ9piBxsoGGv"

如果钱包被锁住，可以通过下面的命令解锁:

1
cleos --wallet-url http://127.0.0.1:8899 wallet unlock -n default --password PW5Juu3fMoX6wK3rV4kMeZToXitspmWLHw3k1zpx7BJ9piBxsoGGv

3、导入初始的eosio的密钥

[root@dbl14195 eos]# cleos --wallet-url http://127.0.0.1:8899 -u http://127.0.0.1:48888 wallet import --private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

启动第一个节点

我们可以使用初始的密钥5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3启动第一个节点。

配置和第一篇文章中的一样：

http-server-address = 0.0.0.0:48888
# The actual host:port used to listen for incoming p2p connections. (eosio::net_plugin)
p2p-listen-endpoint = 0.0.0.0:49876
producer-name = eosio
signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

plugin = eosio::chain_api_plugin
plugin = eosio::http_plugin
plugin = eosio::history_api_plugin
1
nodeos -d eos1/data --config-dir eos1/config &

启动第二个节点

1、首先加载eosio.bios合约

[root@dbl14195 eos]# cleos --wallet-url http://127.0.0.1:8899 -u http://127.0.0.1:48888  set contract eosio /data1/eos/eos/build/contracts/eosio.bios

#         eosio <= eosio::setcode               {"account":"eosio","vmtype":0,"vmversion":0,"code":"0061736d0100000001621260037f7e7f0060057f7e7e7e7e...
#         eosio <= eosio::setabi                {"account":"eosio","abi":"0e656f73696f3a3a6162692f312e30050c6163636f756e745f6e616d65046e616d650f7065...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

这个合约允许你可以直接控制其他账号的资源分配，访问 privileged API。

2、创建新的密钥

1
2
3
[root@dbl14195 eos]# cleos create key --to-console
Private key: 5KcEKvuxxTvShQUCYKT7FKVdA1LJh9CSKTYTCLgCjmmPYL2CjGq
Public key: EOS7mq47SiZVXyw9R3CeGoEsh5YeEtEpmasWL8H14E9a3mrUnbq1B

然后再导入到钱包:

1
cleos --wallet-url http://127.0.0.1:8899 -u http://127.0.0.1:48888 wallet import --private-key 5KcEKvuxxTvShQUCYKT7FKVdA1LJh9CSKTYTCLgCjmmPYL2CjGq

3、创建新的账号

[root@dbl14195 eos]# cleos --wallet-url http://127.0.0.1:8899 -u http://127.0.0.1:48888 create account eosio admin1 EOS7mq47SiZVXyw9R3CeGoEsh5YeEtEpmasWL8H14E9a3mrUnbq1B EOS7mq47SiZVXyw9R3CeGoEsh5YeEtEpmasWL8H14E9a3mrUnbq1B
executed transaction: 930cf193cf5604298570ec843d3f25c79157266121638eaaff36a8c3c52de1e1  200 bytes  459 us
#         eosio <= eosio::newaccount            {"creator":"eosio","name":"admin1","owner":{"threshold":1,"keys":[{"key":"EOS7mq47SiZVXyw9R3CeGoEsh5...
warning: transaction executed locally, but may not be confirmed by the network yet         ]

4、配置第二个节点

修改第二个节点的配置文件，处理端口和地址的修改，注意配置下面两个项：

1
2
producer-name = admin1
signature-provider = EOS7mq47SiZVXyw9R3CeGoEsh5YeEtEpmasWL8H14E9a3mrUnbq1B=KEY:5KcEKvuxxTvShQUCYKT7FKVdA1LJh9CSKTYTCLgCjmmPYL2CjGq

如果你查看第二个节点的输出，回发现还是一直由eosio出块，admin1一直是idle的。

5、激活producer

为了激活admin1, 需要注册admin1到bios节点, bios节点需要更新producer schedule。

1
cleos --wallet-url http://127.0.0.1:8899 -u http://127.0.0.1:48888 push action eosio setprods "{ \"schedule\": [{\"producer_name\": \"admin1\",\"block_signing_key\": \"EOS7mq47SiZVXyw9R3CeGoEsh5YeEtEpmasWL8H14E9a3mrUnbq1B\"}]}" -p eosio@active

注意我们设置了两个producer,你可以看到它们轮流出块：

本文介绍了使用eosio.bios 合约创建多个producer的例子，一般用于链启动的时刻。 进一步，你可以使用其他的智能合约，通过投票的方式选举producer。
