區塊鏈100講：EOS環境安裝和智能合約部署實戰

1

硬件配置

操做系統要求

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)

系統需求

1.8G內存

2.20G空閒硬盤

這是官方給出的支持的操做系統，我的建議，儘可能不要在windows安裝linux虛擬機，會出現不少意想不到的C++安裝包的問題。我用的mac版本是10.13.4。

安裝EOS環境

克隆代碼

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

若是克隆代碼時，沒加–recursive屬性，克隆完以後，須要在命令行中cd到下載的eos目錄，再次執行以下命令:

git submodule update --init --recursive

執行編譯腳本

在命令行中進入到eos目錄，執行編譯腳本:

./eosio_build.sh

大概須要10分鐘，看網速狀況了。編譯完成後，出現以下所示log: 

請仔細看這裏的error日誌，提示build下面的hello.wast找不到，若是隻有這個error，請忽略它(這是官方的bug，之前編譯是沒有的，並且，這個error也並不會影響後面的正常操做)

安裝可執行腳本

cd build

sudo make install

這個安裝速度會有點慢，個人是1小時左右。安裝成功後，應該能看到以下所示log:

若是編譯腳本或者安裝可執行腳本時，出現部分安裝包安裝不了的狀況，請從新執行命令，或者刪除build目錄，再次執行編譯命令。若是這兩種也都無法解決的，請留言給我，或者帶着error日誌移步到官方issue，目前來講，官方issue是解決問題最多的地方，百度和google並無卵用。

啓動本地私有節點

在控制檯中任意目錄執行以下命令

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

啓動成功後，會在本地產生區塊，log以下: 

經過log分析，能夠看到eosio root，也就是區塊生成後的本地存放地點，以及ip，端口，還有一些RPC形式的API。cd到eosio root目錄下:

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

luoxiaohui:eosio luoxiaohui$ ls
nodeos

luoxiaohui:eosio luoxiaohui$ open nodeos/

能夠看到以下目錄：

其中的config.ini，就是本地節點的配置文件了，裏面有各個屬性參數，這裏不一一講了，有想法的本身去改了玩玩。

開啓keosd服務

另外打開一個命令行，執行以下命令：

keosd --http-server-address=127.0.0.1:8900

使用cleos命令建立錢包/密鑰對/帳戶/部署合約等

建立錢包

luoxiaohui:~ luoxiaohui$ cleos wallet create

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

建立密鑰對

luoxiaohui:~ luoxiaohui$ cleos create key

Private key: 5JohgswbXLNLFukkLHe8Na5uPBDi7TZBTRTrkLgbfDqwo7ZCA4X

Public key: EOS6YnSB38qj7Z6ERet1rF6r4Z9azarPADMAGzrTCrCqjanw9fzXC

建立帳戶

先強調下，我目前所在的EOS版本是1.0.5，EOS幾乎每升級一個小的版本，都會有蠻大的改變。目前1.0.5的坑我是躺平了，後面若是還有升級，升級後執行cleos命令有bug，請第一時間拷貝error日誌到官方issue去找答案。

目前，1.0.5版本去部署bios合約時，有了大的改版，在前面提到的config.ini文件中屏蔽掉private-key，並設置以下屬性:

signature-provider=EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

而後，建立eos的帳戶須要用到密鑰對中的公鑰，而在使用cleos命令建立帳戶以前，須要將此公鑰所對應的私鑰導入到錢包中，才能建立帳戶，不然會報錯。最最重要的，就是隻有部署了合約的帳號，才能去建立帳號，具體命令以下：

luoxiaohui:eos luoxiaohui$ cleos wallet createCreating wallet: default

Save password to use in the future to unlock this wallet.
