本教程将解释如何在一台服务器（电脑）上建多个eos节点。
打开电脑一个终端窗口，输入以下命令：
keosd --http-server-address 127.0.0.1:8899
正常情况下，会出现以下信息：
2493323ms thread-0 wallet_plugin.cpp:39 plugin_initialize ] initializing wallet plugin
2493323ms thread-0 http_plugin.cpp:141 plugin_initialize ] host: 127.0.0.1 port: 8899
2493323ms thread-0 http_plugin.cpp:144 plugin_initialize ] configured http to listen on 127.0.0.1:8899
2493323ms thread-0 http_plugin.cpp:213 plugin_startup ] start listening for http requests
2493324ms thread-0 wallet_api_plugin.cpp:70 plugin_startup ] starting wallet_api_plugin
...
以上此打开的终端窗口不要关闭，另外再启动一个终端窗口。在新的终端窗口，输入：
cleos --wallet-url http://localhost:8899 wallet create
以上命令将在8899端口的节点上，新建了一个钱包，结果如下：
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"新账号的hash"
注意端口号与上面一个一致，都是8899。
打开第三个终端，输入以下命令：
nodeos --enable-stale-production --producer-name eosio --plugin eosio::chain_api_plugin --plugin eosio::net_api_plugin
以上命令用于建立一个特殊的BP（记账节点）
要启动第二个节点，首先需要加载eosio.bios合约。
回到以上第二步，输入以下命令：
cleos --wallet-url http://localhost:8899 set contract eosio build/contracts/eosio.bios
首先，生成密钥对
cleos create key
然后，将私钥导入钱包
cleos --wallet-url http://localhost:8899 wallet import 5JgbL2ZnoEAhTudReWH1RnMuQS6DBeLZt4ucV6t8aymVEuYg7sr
imported private key for: EOS6hMjoWRF2L8x9YpeqtUEcsDKAyxSuM1APicxgRU1E3oyV5sDEg
最后，创建inita帐号
cleos --wallet-url http://localhost:8899 create account eosio inita EOS6hMjoWRF2L8x9YpeqtUEcsDKAyxSuM1APicxgRU1E3oyV5sDEg EOS6hMjoWRF2L8x9YpeqtUEcsDKAyxSuM1APicxgRU1E3oyV5sDEg
executed transaction: d1ea511977803d2d88f46deb554f5b6cce355b9cc3174bec0da45fc16fe9d5f3 352 bytes 102400 cycles
# eosio <= eosio::newaccount {"creator":"eosio","name":"inita","owner":{"threshold":1,"keys":[{"key":"EOS6hMjoWRF2L8x9YpeqtUEcsDK...
打开第四个终端窗口，输入命令：
nodeos --producer-name inita --plugin eosio::chain_api_plugin --plugin eosio::net_api_plugin --http-server-address 127.0.0.1:8889 --p2p-listen-endpoint 127.0.0.1:9877 --p2p-peer-address 127.0.0.1:9876 --config-dir node2 --data-dir node2 --private-key [\"EOS6hMjoWRF2L8x9YpeqtUEcsDKAyxSuM1APicxgRU1E3oyV5sDEg\",\"5JgbL2ZnoEAhTudReWH1RnMuQS6DBeLZt4ucV6t8aymVEuYg7sr\"]
正常的话，应该可以看到如下内容：
2393147ms thread-0 producer_plugin.cpp:176 plugin_startup ] producer plugin: plugin_startup() end
2393157ms thread-0 net_plugin.cpp:1271 start_sync ] Catching up with chain, our last req is 0, theirs is 8249 peer dhcp15.ociweb.com:9876 - 295f5fd

2396002ms thread-0 producer_plugin.cpp:244 block_production_loo ] Not producing block because it isn't my turn, its eosio
注意以上命令中的端口。
打开第五个终端，输入以下命令：
cleos --wallet-url http://localhost:8899 push action eosio setprods "{ \"version\": 1, \"producers\": [{\"producer_name\": \"inita\",\"block_signing_key\": \"EOS6hMjoWRF2L8x9YpeqtUEcsDKAyxSuM1APicxgRU1E3oyV5sDEg\"}]}" -p eosio@active
executed transaction: 2cff4d96814752aefaf9908a7650e867dab74af02253ae7d34672abb9c58235a 272 bytes 105472 cycles

可以通过get info完成验证，如通过RPC调用，查看内容是否正确。
cleos --url http://localhost:8889 get info
