EOS节点搭建

查看服务器操作系统版本

cat /proc/version
Linux version 4.4.0-102-generic (buildd@lgw01-amd64-055) (gcc version 5.4.0 20160609 (Ubuntu 5.4.0-6ubuntu1~16.04.5) ) #125-Ubuntu SMP Tue Nov 21 15:15:11 UTC 2017

查看服务器磁盘使用

df -hl
Filesystem      Size  Used Avail Use% Mounted on
udev            3.9G     0  3.9G   0% /dev
tmpfs           799M  4.7M  794M   1% /run
/dev/vda1       345G  243G   85G  75% /

看这行：/dev/vda1 345G 243G 85G 75% ，还剩下85G可用空间。

一个EOS节点大约需要20G。

执行下面命令安装EOS节点

wget https://github.com/eosio/eos/releases/download/v1.4.4/eosio_1.4.4-1-ubuntu-16.04_amd64.deb
$ sudo apt install ./eosio_1.4.4-1-ubuntu-16.04_amd64.deb

执行完毕后nodeos将安装到/usr/bin下。

任意找个位置创建一个测试节点启动脚本

touch eos-test.sh
chmod 744 eos-test.sh

输入如下内容

nodeos -e -p eosio -d /eosdata --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --contracts-console --filter-on "*" --access-control-allow-origin "*"

解释下其中的几个参数：

-p eosio 区块产生者的账户，这里设定为系统账户eosio

-d /eosdata 区块链数据存放的目录

--plugin 开启指定插件

--contracts-console 开启控制台

启动节点

./eos-test.sh

出现下面的生产区块日志，就表示启动成功。

通过cleos与EOS节点和钱包交互

cleos get info
{
  "server_version": "59626f1e",
  "chain_id": "cf057bbfb72640471fd910bcb67639c22df9f92470936cddc1ade0e2f2e7dc4f",
  "head_block_num": 2779,
  "last_irreversible_block_num": 2778,
  "last_irreversible_block_id": "00000ada125d953aba94e94b2aa8a15b1773345766bab1863c6f6e977e2343d6",
  "head_block_id": "00000adb93c1f0fda3e8e21a180f98e49cb0840e71416476b402dd4837358f2f",
  "head_block_time": "2018-11-21T06:17:39.000",
  "head_block_producer": "eosio",
  "virtual_block_cpu_limit": 3214242,
  "virtual_block_net_limit": 16884231,
  "block_cpu_limit": 199900,
  "block_net_limit": 1048576,
  "server_version_string": "v1.4.4"
}

chain id唯一标识了一条EOS链，这里我启动的是条本地测试链。

可以通过指定主网peer节点来连接主网，比如我们连接主网节点http://mainnet.genereos.io:80

 cleos --url=http://mainnet.genereos.io:80 get info
{
  "server_version": "99d94446",
  "chain_id": "aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906",
  "head_block_num": 28055941,
  "last_irreversible_block_num": 28055607,
  "last_irreversible_block_id": "01ac183760816ad2812e4c442ca53bb3e41040841b577d81e2d08ade18850f62",
  "head_block_id": "01ac19850756798d85bdb52ab48d7ef4432113f991e6d795cc99e5bbe713c8b7",
  "head_block_time": "2018-11-21T06:27:05.000",
  "head_block_producer": "eos42freedom",
  "virtual_block_cpu_limit": 4920210,
  "virtual_block_net_limit": 1048576000,
  "block_cpu_limit": 176543,
  "block_net_limit": 1045016,
  "server_version_string": "mainnet-1.4.1"
}

主链的chain id是aca376f206b8fc25a6ed44dbdc66547c36c6c33e3a119ffbeaef943642f0e906

区块数28055941

可以和浏览器https://eospark.com/MainNet/数据对应起来。

可以通过添加--p2p-peer-address p2p.meet.one:9876 --genesis-json /genesis.json来启动nodeos，这样节点可以加入主网。

genesis.json文件从https://github.com/EOS-Mainnet/eos/blob/launch-rc-1.0.2/mainnet-genesis.json获取，放置在eosdata目录下。

全节点上网找或者https://docs.google.com/spreadsheets/u/1/d/1K_un5Vak3eDh_b4Wdh43sOersuhs0A76HMCfeQplDOY/htmlview?sle=true#gid=0里取一个。

钱包生成

cleos wallet create --to-console -n test 
Creating wallet: test
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5HwmHNRee71Hke6ADGCSYFWrjjbssrzuNY95hmyQAGdCS57uPDR"

记住这个钱包密码，后续用于解锁钱包。

还需要把eosio账户的私钥导入到钱包中才能控制该账户，eosio账户的私钥在config.ini文件中。

系统默认的配置文件：~/.local/share/eosio/nodeos/config/config.ini

其中signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

记录了默认区块生产者eosio的公私钥对，前面的是公钥，key后面的是私钥。

导入eosio账户的私钥到test钱包。

cleos wallet import -n test --private-key 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

接下来再用钱包test创建一个个人账户test，下面的命令生成了一对新的公私钥对并导入到钱包里。

cleos wallet create_key -n test
Created new private key with a public key of: "EOS5mPPFpdAjMKWxYeYyWiyjNhghbUUyiqXw4yhhRnUApJQbnPACQ"

生成账户test，并关联上面生成的公钥，这里省略了一个active公钥，只填了一个owner公钥。

# cleos wallet keys
[
  "EOS5mPPFpdAjMKWxYeYyWiyjNhghbUUyiqXw4yhhRnUApJQbnPACQ",
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"
]
# cleos create account eosio test EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

warning: transaction executed locally, but may not be confirmed by the network yet         ]

生成合约

安装合约开发工具EOS.cdt

$ wget https://github.com/eosio/eosio.cdt/releases/download/v1.4.1/eosio.cdt-1.4.1.x86_64.deb
$ sudo apt install ./eosio.cdt-1.4.1.x86_64.deb

新建hello.cpp文件

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>
using namespace eosio;
class hello : public contract {
  public:
      using contract::contract;
      [[eosio::action]]
      void hi( name user ) {
         print( "Hello, ", name{user});
      }
};
EOSIO_DISPATCH( hello, (hi))

编译

eosio-cpp -o hello.wasm hello.cpp --abigen

生成了hello.abi和hello.wasm

cat hello.abi 
{
    "____comment": "This file was generated with eosio-abigen. DO NOT EDIT Wed Nov 21 16:04:26 2018",
    "version": "eosio::abi/1.1",
    "structs": [
        {
            "name": "hi",
            "base": "",
            "fields": [
                {
                    "name": "user",
                    "type": "name"
                }
            ]
        }
    ],
    "types": [],
    "actions": [
        {
            "name": "hi",
            "type": "hi",
            "ricardian_contract": ""
        }
    ],
    "tables": [],
    "ricardian_clauses": [],
    "variants": [],
    "abi_extensions": []
}

部署合约

记住，这时我们有两个账户，一个默认账户eosio，一个个人账户test

如果钱包锁住的话先解锁钱包

# cleos wallet unlock -n test --password PW5HwmHNRee71Hke6ADGCSYFWrjjbssrzuNY95hmyQAGdCS57uPDR
Unlocked: test

然后用账户eosio发布合约

cleos set contract eosio /root/contract/ hello.wasm hello.abi -p eosio@active
Reading WASM from /root/contract/hello.wasm...
Publishing contract...
executed transaction: 4f1f10536dc09095366f8d18ecd2d4ef6b3755cbcf38865f6a8103f25730500c  1432 bytes  747 us

warning: transaction executed locally, but may not be confirmed by the network yet         ]

这笔交易长这样

# cleos get transaction 4f1f10536dc09095366f8d18ecd2d4ef6b3755cbcf38865f6a8103f25730500c

很长，不在这里显示全部了。

调用合约

# cleos push action eosio hi '["wormhole"]' -p test@active
executed transaction: aff91ac7a7d4f1467c610e4eb593071810f230ce8d53b5bd946fdc3753bcf59f  104 bytes  539 us
#         eosio <= eosio::hi                    {"user":"wormhole"}
>> Hello, wormhole
warning: transaction executed locally, but may not be confirmed by the network yet         ]

这里的eosio为被调用合约代码的账户，hi为调用方法，'["wormhole"]'为参数，实际的参数用'[ ]'包起来，-p表示哪个账户发起调用，发起这个动作用的什么权限，权限分为active和owner。

可以看到合约已成功执行：>> Hello, wormhole
