区块链100讲:EOS环境安装和智能合约部署实战

1

硬件配置

操作系统要求

1.Amazon 2017.09 and higher

2.Centos 7

3.Fedora 25 and higher (Fedora 27 recommended)

4. Mint 18

5. Ubuntu 16.04 LTS (Ubuntu 16.10 recommended)

6. Ubuntu 18.04 LTS7. MacOS Darwin 10.12 and higher (MacOS 10.13.x recommended)

系统需求

1.8G内存

2.20G空闲硬盘

这是官方给出的支持的操作系统,个人建议,尽量不要在windows安装linux虚拟机,会出现很多意想不到的C++安装包的问题。我用的mac版本是10.13.4。

2

安装EOS环境

克隆代码

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

如果克隆代码时,没加–recursive属性,克隆完之后,需要在命令行中cd到下载的eos目录,再次执行如下命令:

git submodule update –init –recursive

执行编译脚本

在命令行中进入到eos目录,执行编译脚本:

./eosio_build.sh

大概需要10分钟,看网速情况了。编译完成后,出现如下所示log:

区块链100讲:EOS环境安装和智能合约部署实战

请仔细看这里的error日志,提示build下面的hello.wast找不到,如果只有这个error,请忽略它(这是官方的bug,以前编译是没有的,而且,这个error也并不会影响后面的正常操作)

安装可执行脚本

cd build

sudo make install

这个安装速度会有点慢,我的是1小时左右。安装成功后,应该能看到如下所示log:

如果编译脚本或者安装可执行脚本时,出现部分安装包安装不了的情况,请重新执行命令,或者删除build目录,再次执行编译命令。如果这两种也都没法解决的,请留言给我,或者带着error日志移步到官方issue,目前来说,官方issue是解决问题最多的地方,百度和google并没有卵用。

启动本地私有节点

在控制台中任意目录执行如下命令

nodeos -e -p eosio –plugin eosio::chain_api_plugin –plugin eosio::history_api_plugin –replay-blockchain –max-irreversible-block-age 1801

启动成功后,会在本地产生区块,log如下:

通过log分析,可以看到eosio root,也就是区块生成后的本地存放地点,以及ip,端口,还有一些RPC形式的API。cd到eosio root目录下:

luoxiaohui:~ luoxiaohui$ cd /Users/luoxiaohui/Library/Application Support/eosio/

luoxiaohui:eosio luoxiaohui$ lsnodeos

luoxiaohui:eosio luoxiaohui$ open nodeos/

可以看到如下目录:

其中的config.ini,就是本地节点的配置文件了,里面有各个属性参数,这里不一一讲了,有想法的自己去改了玩玩。

开启keosd服务

另外打开一个命令行,执行如下命令:

keosd –http-server-address=127.0.0.1:8900

使用cleos命令创建钱包/密钥对/账户/部署合约等

创建钱包

luoxiaohui:~ luoxiaohui$ cleos wallet create

Creating wallet: defaultSave password to use in the future to unlock this wallet.Without password imported keys will not be retrievable.”PW5J37EZS54NyQSugYtW6LQsERgUNB9xCpCiEpnauR9qzsJGcN8vQ”

创建密钥对

luoxiaohui:~ luoxiaohui$ cleos create key

Private key: 5JohgswbXLNLFukkLHe8Na5uPBDi7TZBTRTrkLgbfDqwo7ZCA4X

Public key: EOS6YnSB38qj7Z6ERet1rF6r4Z9azarPADMAGzrTCrCqjanw9fzXC

创建账户

先强调下,我目前所在的EOS版本是1.0.5,EOS几乎每升级一个小的版本,都会有蛮大的改变。目前1.0.5的坑我是躺平了,后面如果还有升级,升级后执行cleos命令有bug,请第一时间拷贝error日志到官方issue去找答案。

目前,1.0.5版本去部署bios合约时,有了大的改版,在前面提到的config.ini文件中屏蔽掉private-key,并设置如下属性:

signature-provider=EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

然后,创建eos的账户需要用到密钥对中的公钥,而在使用cleos命令创建账户之前,需要将此公钥所对应的私钥导入到钱包中,才能创建账户,否则会报错。最最重要的,就是只有部署了合约的账号,才能去创建账号,具体命令如下:

luoxiaohui:eos luoxiaohui$ cleos wallet createCreating wallet: default

Save password to use in the future to unlock this wallet.Without password imported keys will not be retrievable.”PW5Kjfs7MYmbFtN4dFKoNUh1nKMvYV3nvyMcnDpLW3ZbfH7P8VSzn”luoxiaohui:eos

创建代币

切记,只有部署过合约的账户,才能创建代币.

创建一个叫FB的代币

luoxiaohui:eos luoxiaohui$ cleos push action test1 create ‘[ “eosio”, “100000000.0000 FB” ]’ -p test1executed transaction: 237196f8ffacff045cf8a5e7b8aa0a6b11b8d149f64a9f02465f5da476c1198c 120 bytes 2247 us# test1 <= test1::create {“issuer”:”eosio”,”maximum_supply”:”100000000.0000 FB”}warning: transaction executed locally, but may not be confirmed by the network yetluoxiaohui:eos luoxiaohui$ cleos create account eosio test3 EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CVexecuted transaction: 8697a79671dd815cb6938e83b10609adccc68bb32931e7ec3043547861751777 200 bytes 212 us# eosio <= eosio::newaccount {“creator”:”eosio”,”name”:”test3″,”owner”:{“threshold”:1,”keys”:[{“key”:”EOS6MRyAjQq8ud7hVNYcfnVPJqc…warning: transaction executed locally, but may not be confirmed by the network yetluoxiaohui:eos luoxiaohui$ cleos push action test1 issue ‘[ “test3″,”100000000.0000 FB”, “memo” ]’ -p eosioexecuted transaction: 00e87d6a189087934ff81e1f33a0c4f004cf1ad1fb73371ab25ae7aa0237be74 128 bytes 2581 us# test1 <= test1::issue {“to”:”test3″,”quantity”:”100000000.0000 FB”,”memo”:”memo”}# test1 <= test1::transfer {“from”:”eosio”,”to”:”test3″,”quantity”:”100000000.0000 FB”,”memo”:”memo”}# eosio <= test1::transfer {“from”:”eosio”,”to”:”test3″,”quantity”:”100000000.0000 FB”,”memo”:”memo”}# test3 <= test1::transfer {“from”:”eosio”,”to”:”test3″,”quantity”:”100000000.0000 FB”,”memo”:”memo”}warning: transaction executed locally, but may not be confirmed by the network yet

转账

账户test3转账给test2

1.luoxiaohui:eos luoxiaohui$ cleos push action test1 transfer ‘[ “test3”, “test2”, “25.0000 FB”, “m” ]’ -p test3

2.executed transaction: a5bb2c5bd92d7fee1a24efb4fa0afcc66ac8da39be0036aa55a2cf070049e8ac 128 bytes 595 us

3.# test1 <= test1::transfer {“from”:”test3″,”to”:”test2″,”quantity”:”25.0000 FB”,”memo”:”m”}

4.# test3 <= test1::transfer {“from”:”test3″,”to”:”test2″,”quantity”:”25.0000 FB”,”memo”:”m”}

5.# test2 <= test1::transfer {“from”:”test3″,”to”:”test2″,”quantity”:”25.0000 FB”,”memo”:”m”}

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

查询代币余额

这里的test1,表示创建了FB这个代币的账户,test2表示需要查询的账户,FB表示代币名称。

1.luoxiaohui:eos luoxiaohui$ cleos get currency balance test1 test2 FB

2.25.0000 FB
