環境要求

Ubuntu 16.04
內存4G以上（官方要求8G，可以通過修改文件降低要求）

編譯安裝

clone源碼

jian@ubuntu:~$ git clone https://github.com/eosio/eos.git --recursive

需要注意的是，MongoDB是EOS的依賴項之一，而在牆內下載該依賴項會失敗，請先科學上網，再開始編譯，否則會無法下載MongoDB導致編譯失敗。

編譯

jian@ubuntu:~$ cd eos
jian@ubuntu:~/eos$ sudo ./eosio_build.sh   #需要3個小時左右，遇到錯誤請往下看

如果提示下面的信息，說明內存達不到要求，至少需要7G以上內存空間

    ......
    Your system must have 7 or more Gigabytes of physical memory installed.
    Exiting now.

將VMware的內存增加到4G多一點，記住要多一點，然後修改./scripts/eosio_build_ubuntu.sh文件,查找7000，將7000修改爲4000即可，意思是將配置要求降低到4G內存。

如果看到下面的5個紅色大字表示已經編譯完成了，除開填坑的時間花了整整4個小時。

編譯完成後安裝

jian@ubuntu:~/eos$ cd build
jian@ubuntu:~/eos/build$ sudo make install

在./programs這個文件夾中可以找到eos的幾個核心程序

nodeos：區塊鏈服務器節點生成組件。nedeos的配置文件位於~/Library/Application Support/eosio/nodeos/config文件夾中，區塊數據存儲在文件~/Library/Application Support/eosio/nodeos/data中
cleos：和區塊鏈交互的接口命令
keosd： EOS 錢包，作用是存儲私鑰，以便cleos用以簽署交易併發送到區塊鏈中。keosd在本機運行，並且將私鑰存儲在本地。keosd會隨着cleos自動啓動。
eosio-launcher：節點網絡組成和部署的應用

啓動節點

jian@ubuntu:~/eos/build$ cd ~/eos/build/programs/nodeos
jian@ubuntu:~/eos/build/programs/nodeos$ sudo ./nodeos -e -p eosio -d /data/eos --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --plugin eosio::bnet_plugin --contracts-console --filter-on "*" --access-control-allow-origin "*" --max-transaction-time=1000 --verbose-http-errors

參數說明：

-p：表示使用了本地測試系統提供的原始賬戶 eosio 賬戶的權限

-d：區塊數據存放目錄

–plugin：插件

-e：開啓Stale Production，即即便當前時間已經超過規定的區塊生產時限，也繼續產生

–plugin eosio::chain_api_plugin：開啓區塊鏈JSON API插件。

–plugin eosio::history_api_plugin：開啓歷史數據插件，有了這個插件，便能查詢許多不在State中的數據，譬如一個公鑰所對應的所有賬戶等等。

–contracts-console：開啓合約控制檯。如果不開啓的話，合約中調用print函數輸出的信息將會不可見。

–filter-on “*”：開啓所有賬戶的歷史紀錄。默認狀態下，節點不會記錄賬戶的歷史數據，從而使得命令cleos get actions返回空。

–access-control-allow-origin “*”：允許任意域名跨域訪問API，如果不開啓，在dApp開發中，網站會報錯。

上面的啓動命令比較長，可以將參數寫入配置文件

jian@ubuntu:~/eos/build/programs/cleos$ cd ~/.local/share/eosio/nodeos/config
jian@ubuntu:~/.local/share/eosio/nodeos/config$ vi config.ini

修改或新增以下內容：

	# 下面是修改的
    enable-stale-production = true # 修改false爲true
    filter-on = *
    producer-name = eosio
    
    # 下面的插件是新增的，加在文件最後
    # Load the block producer plugin, so you can produce blocks
    plugin = eosio::producer_plugin
    # As well as API and HTTP plugins
    plugin = eosio::chain_api_plugin
    plugin = eosio::http_plugin
    # This will be used by the validation step below, to view history
    plugin = eosio::history_api_plugin
    plugin = eosio::bnet_plugin

然後啓動節點

jian@ubuntu:~/eos/build$ cd ~/eos/build/programs/nodeos
jian@ubuntu:~/eos/build/programs/nodeos$ sudo ./nodeos

停止節點

按下Ctrl+C即可停止節點

導入私鑰

首先我們需要創建一個默認的錢包，請記住的到的私鑰

jian@ubuntu:~$ cd ~/eos/build/programs/cleos
jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet create --to-console
"/home/jian/eos/build/programs/keosd/keosd" launched
Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5JXUScSE7QnskHEjuwXBVwfYnjozaHFC6MA4ouDrLX9L7XZNkzF"

這裏創建了錢包名爲default，密碼爲"PW5JXUScSE7QnskHEjuwXBVwfYnjozaHFC6MA4ouDrLX9L7XZNkzF"的錢包。

打開錢包看看有什麼內容 (如果錢包已經鎖定，需要先解鎖錢包)：

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet keys
[
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV"
]

可以看到新創建的錢包中有一個密鑰對，這是唯一的初始帳戶eosio的主密鑰對，不要將上述主密鑰與你將來添加的密鑰混淆。

進入配置文件

jian@ubuntu:~/eos/build/programs/cleos$ cd ~/.local/share/eosio/nodeos/config
jian@ubuntu:~/.local/share/eosio/nodeos/config$ vi config.ini

找到這一行

signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

這是指定了默認區塊產生者eosio的公私鑰對，其中公鑰爲：EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV

相對應的私鑰爲：5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3

爲什麼錢包中已經有密鑰對了還要再添加？

每個EOS帳戶都擁有owner(所有者)和active(活動權限)兩個權限，因此，在大多數情況下，需要創建兩個密鑰，以便可以將一個密鑰與每個權限相關聯。

首先創建兩個密鑰對

jian@ubuntu:~$ cd ~/eos/build/programs/cleos
jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos create key --to-console
Private key: 5JxhYZZnFJJMRrf7KkSHNLFq2LM4eZigJfeKXXYSa1TvPMdWtLc
Public key: EOS5Fwtc4vnQE8AigimXvHrERrK7XFpycQ8Dijq2611timbVTReDt

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos create key --to-console
Private key: 5JXNT5zRfFDwzc7mKmd3AiYjT9dvfDosiFAo1drkneY6TrhTRUp
Public key: EOS75hPAeMGgAw9FYLTAHqjHyicjW82bB1q9grXqDtCdMDMpe1eoa

然後依次將兩個Private key導入到創建的默認錢包中

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet import --private-key 5JxhYZZnFJJMRrf7KkSHNLFq2LM4eZigJfeKXXYSa1TvPMdWtLc
imported private key for: EOS5Fwtc4vnQE8AigimXvHrERrK7XFpycQ8Dijq2611timbVTReDt
jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet import --private-key 5JXNT5zRfFDwzc7mKmd3AiYjT9dvfDosiFAo1drkneY6TrhTRUp
imported private key for: EOS75hPAeMGgAw9FYLTAHqjHyicjW82bB1q9grXqDtCdMDMpe1eoa

可以看到導入私鑰後會自動給出對應的公鑰。

在次打開默認錢包可以看到默認錢包中已經有3個密鑰對了

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet keys
[
  "EOS5Fwtc4vnQE8AigimXvHrERrK7XFpycQ8Dijq2611timbVTReDt",
  "EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV",
  "EOS75hPAeMGgAw9FYLTAHqjHyicjW82bB1q9grXqDtCdMDMpe1eoa"
]

發行代幣

在部署eosio.EOStem合約之前，必須先創建如下賬戶，創建賬號使用eosio的公私鑰對：

EOStemAccounts = [
    'eosio.bpay',
    'eosio.msig',
    'eosio.names',
    'eosio.ram',
    'eosio.ramfee',
    'eosio.saving',
    'eosio.stake',
    'eosio.token',
    'eosio.upay',
]

創建命令如下：

sudo ./cleos create account eosio eosio.bpay EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.msig EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.names EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.ram EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.ramfee EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.saving EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.stake EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.token EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;
sudo ./cleos create account eosio eosio.upay EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV;

執行的結果如下：

......

接下來將代幣合約部署到eosio.token賬戶中：

jian@ubuntu:~/eos/build/programs/cleos$ cd ~/eos/build/contracts  # 進入編譯後的合約目錄
jian@ubuntu:~/eos/build/contracts$ sudo ~/eos/build/programs/cleos/cleos set contract eosio.token ./eosio.token

創建1億個EOS代幣（這裏的EOS幣相當於主網中的EOS）：

jian@ubuntu:~/eos/build/contracts$ sudo ~/eos/build/programs/cleos/cleos push action eosio.token create '["eosio","10000000000.0000 SYS",0,0,0]' -p eosio.token

發行代幣，數量：10000000000，代幣符號：EOS。

jian@ubuntu:~/eos/build/contracts$ sudo ~/eos/build/programs/cleos/cleos push action eosio.token issue '["eosio","10000000000.0000 EOS","issue"]' -p eosio

查詢代幣數量

jian@ubuntu:~/eos/build/contracts$ sudo ~/eos/build/programs/cleos/cleos get currency balance eosio.token eosio

10000000000.0000 EOS

創建賬號

在EOS中，爲了控制權限，創建賬號是需要指定一個創建者的，例如默認錢包的創建者是eosio，所以創建default賬號中含有eosio的私鑰。

創建賬戶的格式如下：

cleos create account AUTHORIZING_ACCOUNT NEW_ACCOUNT OWNER_KEY ACTIVE_KEY

authorizing_account 是新賬戶的創建者。在此教程中，由於我們運行的是一個單節點測試網絡，所以我們擁有一個名爲eosio的系統賬戶，因此我們使用eosio作爲新賬戶的創建者
new_account 是要創建的賬戶名稱
owner_key 是賬戶owner權限的公鑰
active_key 是賬戶active權限的公鑰

我們使用account1作爲新賬戶名稱，使用eosio作爲新賬戶的創建者，使用之前生成並導入default錢包的兩個公鑰EOS5Fwtc4vnQE8AigimXvHrERrK7XFpycQ8Dijq2611timbVTReDt和EOS75hPAeMGgAw9FYLTAHqjHyicjW82bB1q9grXqDtCdMDMpe1eoa分別作爲owner權限和active權限的公鑰，注意這裏是使用公鑰！！！

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos create account eosio account1 EOS5Fwtc4vnQE8AigimXvHrERrK7XFpycQ8Dijq2611timbVTReDt EOS75hPAeMGgAw9FYLTAHqjHyicjW82bB1q9grXqDtCdMDMpe1eoa

我這裏報錯了,因爲交易是需要RAM資源的。如果沒有報錯請忽略下面一步。

Error 3080001: Account using more than allotted RAM usage
Error Details:
account account1 has insufficient ram; needs 2996 bytes has 0 bytes

將創建命令改爲下面的才能成功

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos  system newaccount eosio account1 EOS5Fwtc4vnQE8AigimXvHrERrK7XFpycQ8Dijq2611timbVTReDt EOS75hPAeMGgAw9FYLTAHqjHyicjW82bB1q9grXqDtCdMDMpe1eoa --stake-net '0 EOS' --stake-cpu '0 EOS' --buy-ram-kbytes 3 -x 30

     available:            0 us   
     limit:                0 us

鎖定錢包

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet lock -n jian
Locked: jian

keosd會在沒有錢包指令的15分鐘後自動鎖定錢包，可以在~/eosio-wallet/config.ini中進行時長修改。可以設置一個超大數來取消這項功能。如果設爲0，將會導致錢包永久鎖定。

解鎖錢包

沒有-n指定錢包名會解鎖默認錢包，默認錢包解鎖密碼是"導入私鑰"中創建錢包時得到的PW開頭的私鑰

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet unlock -n jian
password: Unlocked: jian

再次查看錢包，可以看到有*號表示已經解鎖了

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos wallet list
Wallets:
[
  "default",
  "jian *"
]

發送交易

轉100個幣到account1賬號中

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos push action eosio.token transfer '["eosio", "account1","100.0000 EOS","memo"]' -p eosio

查詢account1賬號的餘額

jian@ubuntu:~/eos/build/programs/cleos$ sudo ./cleos get currency balance eosio.token account1
100.0000 EOS
