docker 磁盘io高 docker ce io

本搭建过程根据官网教程（https://developers.eos.io/eosio-home/docs/setting-up-your-environment）进行，主要步骤如下：

一、安装docker

1、Debian 9安装docker ce（过程参照），docker官网的下载需要注册帐号才能下载，未尝试。

二、新建开发目录

shell

$mkdir contracts

$cd contracts

$pwd

结果 /home/game/contracts 向教程网页提交此绝对路径，以便自动生成后续使用代码中的路径。

三、EOS节点安装

1、获得EOS的docker镜像 

$ docker pull eosio/eos:v1.4.2

2、启动节点和钱包

shell（注命令中已包含上面的绝对路径）

docker run --name eosio \
  --publish 7777:7777 \
  --publish 127.0.0.1:5555:5555 \
  --volume /home/game/contracts:/home/game/contracts \
  --detach \
  eosio/eos:v1.4.2 \
  /bin/bash -c \
  "keosd --http-server-address=0.0.0.0:5555 & exec nodeos -e -p eosio --plugin eosio::producer_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_plugin --plugin eosio::history_api_plugin --plugin eosio::http_plugin -d /mnt/dev/data --config-dir /mnt/dev/config --http-server-address=0.0.0.0:7777 --access-control-allow-origin=* --contracts-console --http-validate-host=false --filter-on='*'"

3、检查安装是否正确

3.1确定节点可产生区块

shell

docker logs --tail 10 eosio

正确结果应该类似如下：

3.2检查钱包

• Shell

docker exec -it eosio bash

进入eosio命令行之后，输入：

cleos --wallet-url http://127.0.0.1:5555 wallet list keys

正确结果应为：

Wallets:
[]

退出eosio命令行

exit

3.3检查节点终端

1、网页打开http://localhost:7777/v1/chain/get_info

2、控制台shell命令：

curl http://localhost:7777/v1/chain/get_info

1、2返回的结果内容应该一致，是一个json格式字符串内容。

4、命令别名化cleos

shell

alias cleos='docker exec -it eosio /opt/eosio/bin/cleos --url http://127.0.0.1:7777 --wallet-url http://127.0.0.1:5555'

临时别名直接在控制台运行，如要配置成环境直接生效则需添加进你 的.bash_rc文件

5、其他EOS的docker运行命令：

Start/Stop Container

docker start eosio
docker stop eosio

打开EOS的Bash

docker exec -it eosio bash

Remove the EOSIO Container

docker rm eosio

四、安装EOS合约开发包

debian、ubuntu环境下：

Install   Shell

wget https://github.com/eosio/eosio.cdt/releases/download/v1.3.2/eosio.cdt-1.3.2.x86_64.deb
sudo apt install ./eosio.cdt-1.3.2.x86_64.deb

Uninstall  Shell

sudo apt remove eosio.cdt

 

另外也可以从源码安装，此方式未尝试，有空再试。

五、理解EOS架构

nodeos (node + eos = nodeos)：节点

cleos (cli + eos = cleos) ：命令行终端

keosd (key + eos = keosd) ：钱包管理相关

eosio-cpp ：eosio.cdt的功能之一,将 C++代码编译成 WASM文件，并生成ABIs。个人理解为类似于QT的qmake功能。

六、创建开发钱包

1、创建默认钱包

• Shell

cleos wallet create --to-console

开发环境--to-console选项没有太多安全隐患，生产环境应该使用--to-file。

cleos返回

Creating wallet: default
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5Kewn9L76X8Fpd....................t42S9XCw2"

需注意密码保存好，以便后续继续使用。

2、打开钱包

cleos wallet open

cleos wallet list

将返回：

Wallets:
[
  "default"
]

3、解锁钱包

cleos wallet unlock

cleos wallet list

将返回（注有 *）：

Wallets:
[
  "default *"
]

4、钱包导入keys

cleos wallet create_key

返回类似如下：

Created new private key with a public key of: "EOS8PEJ5FM42xLpHK...X6PymQu97KrGDJQY5Y"

5、向网页教程提交public key以便自动生成后续命令代码内容

此步只在教程中使用。

6、导入开发key

• Shell

cleos wallet import

在提示输入钱包密码，并输入首次使用的系统默认帐号eosio的private key（5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3）之后，输出private key。

至此，你拥有一个默认的解锁的钱包，由key加载，并已得到保护。

 

特别说明：由于默认帐号eosio的公私钥是公开的，生产系统中最好仅用来创建首帐号，之后将其key从钱包中删除，否则会十分危险。

七、创建测试帐号

• Shell

cleos create account eosio bob EOS59pZ8Wu75WDGeSD5cvEvJMfEia436rn4miLDQz6G9sHBJpS3f8 
cleos create account eosio alice EOS59pZ8Wu75WDGeSD5cvEvJMfEia436rn4miLDQz6G9sHBJpS3f8

注：创建了bob、alice两个帐号，EOS59pZ8Wu75WDGeSD5cvEvJMfEia436rn4miLDQz6G9sHBJpS3f8为上述的开发帐号的public key。操作必须在wallet unlock状态下进行。
