EOS私有链搭建

参考文章https://www.jianshu.com/p/f5b90a82e969

源码下载

git clone https://github.com/EOSIO/eos.git --recursive

编译源码

cd eos
./eosio_install.sh
./eosio_build.sh

如果内存低于7G，需要修改配置

vim scripts/eosio_build_ubuntu.sh

if [ "${MEM_MEG}" -lt 7000 ]; then  

如果你的物理内存是4G ，可以把7000改成3000
如果磁盘过低，也需要修改磁盘配置

启动第一个节点

1.在源码外创建一个目录，并在目录里创建data目录和config目录，data用于存放eos运行过程中的数据，config目录用于存放config.ini和genesis.json文件。
2.修改config.ini文件和genesis.json文件

config.ini

#blocks-dir = "blocks"   区块目录，建议屏蔽，自己指定
http-server-address = 0.0.0.0:8888   #http服务器本地监听
p2p-server-address = 192.168.1.132:9898   #配置本地为p2p服务器
p2p-listen-endpoint = 0.0.0.0:9898    #本地节点监听
p2p-peer-address = 192.168.1.132:9898  #其他超级节点，可以配置多个   
agent-name = "EOS Test Agent"  #名称，可以随意修改
allowed-connection = any   #允许任意节点连接
enable-stale-production = true    #第一节点配置为true，允许直接出块，其他超级节点配置为false
max-transaction-time = 1000   #防止部署合约失败，此配置设置为1000
producer-name = eosio   #本节点的账户名称，eosio为创世节点名称，后面几个节点名称分别为inita,initb,initc由自己设定，这些账户在下面脚本中创建
#节点密钥对，eosio节点配置为genesis.json对应公钥即可
signature-provider = EOS5xXJ8LkHDhJWHC5HKz8y9nhq5UaZgxzDMdGbiufrrJXwcCHzH8=KEY:5KMmKcSh4cNWLvASoKqVzoKgC8Gn953byfZnzrVS2XeXirRrVWm  

#文件末尾加上相关插件
plugin = eosio::chain_api_plugin
plugin = eosio::history_api_plugin
plugin = eosio::chain_plugin
plugin = eosio::producer_plugin
plugin = eosio::http_plugin
plugin = eosio::net_plugin
plugin = eosio::net_api_plugin

genesis.json

创世文件，所有节点保存一致。https://github.com/EOSIO/eos/blob/master/tutorials/bios-boot-tutorial/genesis.json

#如果不能出块，可以先运行一次eosio节点，再回填
"initial_timestamp": "2018-12-13T02:02:13.066",    
 #创世区块节点的公钥，必须和源码里的地址一致(不过改了好像改了也可以)
"initial_key": "EOS5xXJ8LkHDhJWHC5HKz8y9nhq5UaZgxzDMdGbiufrrJXwcCHzH8",  
"initial_chain_id": 
"0000000000000000000345000000000000000000000000000000000000000000"    #随意填写

修改完配置文件后，可以启动节点了：

nodeos  --data-dir ./data --config-dir ./config  --genesis-json  ./config/genesis.json

节点启动后就会不断出块了，0.5S一个块。私有链就算是搭起来了,接下来就可以去创建自己的钱包、账户、发行系统代币了。
