EOS环境搭建
【本文目标】 通过本文实践,能在已编译的EOS V1.0.5版本环境上,完成私链节点启动,钱包创建,密钥导入和账号创建等内容。 【前置条件】 你已完成了EOS编译,编译测试成功。未完成的可参考 《第4课 如何在UBUNTU虚拟机上编译EOS完成环境搭建?》 完成相关配置。 【技术收获】 1)EOS的节点,钱包,密钥,账号的概念和理解 2)EOS钱包/账号的建立和遇到的问题分析及解决方法 【说明】 EOS版本还没有稳定下来,即使完成了V1.0.2版本环境搭建的人,到V1.0.5时还是摔在了坑里。辉哥通过踩坑分析给大家提供尽可能多的知识和解决思路,大家在V1.0.5以后的版本部署可参考文章和以错误关键字搜索官网的 issue 网址获取更多知识。
EOSIO有多个程序模块组成,经常会用到的有以下三个模块:
nodeos
- EOSIO核心模块,用于启动eosio服务,在后台运行,启动时可以添加多种插件plugin。cleos
- 命令行界面钱包工具,见 《EOS命令行界面钱包》 ,位于 eos/build/programs/cleos/cleos
keosd
- 管理钱包的各种组件,默认情况下, keosd
将随 cleos
一起启动。位于 eos/build/programs/keosd
另外,还有智能合约的编译工具 eosiocpp
。
相对其他区块链公链,EOS系统的组合关系比较自由,也带来了理解上的困难。辉哥结合自己的理解,以中国大地上人们最关系的房子为例,做比喻介绍。 1) 钱包是土豪房东 土豪可以有很多的房子和各种开门的钥匙。上海这个城市有很多个土豪房东,所以一个节点可以创建多个钱包。
cleos wallet create ${参数}
2)钥匙用来打开房东门的。 钥匙分为私钥和公钥。公钥是别人可以看到的,例如下面图片是土豪家的橙色钥匙包,是专门用来存放仁恒滨江的大平层房子钥匙的,私钥是钥匙包里面实际开门的钥匙。 你拿到钥匙包没有用的,你得拿到钥匙盒里面的私钥才可以打开土豪家房子大门。 土豪房东可以把很多的房子配成一样的锁,用一对公钥/私钥来开门,也可以不同的房子不同的钥匙。
cleos wallet import ${参数} 私钥
3) 账户是房子 房东可以给多个房子配一对钥匙(钥匙包和钥匙),也可以不同房子配不同钥匙。 另外,一个房子可以用2把钥匙打开,一把是owner钥匙对,一把是active钥匙对。 房子的owner钥匙地址表示为房东的公钥,表示主人产权归属,用它对应的私钥可以打开房子,这个钥匙包是房东连小姨子也不会给的; 房子的active钥匙对表示为房客的公钥,表示该用户的私钥可以打开房子,房子出租后,房东就把这个钥匙包给租客了;
cleos create account 节点 账户名 Owner的公钥 Active的公钥
搭建实操的流程图如下。
1) 启动keosd
keosd --http-server-address=127.0.0.1:8900
命令行界面钱包程序为 keosd,位于 eos/build/programs/keosd 路径下,用于存储交易签名的私钥。keosd在本地节点上运行,并将私钥保存在本地节点上。
默认情况下,keosd会在目录 ~/eosio-wallet 中生成一个基础的配置文件 config.ini。该配置文件中的wallet-dir指定了钱包文件存放目录。
另外,在运行命令行钱包时,可通过配置命令行参数 --config-dir指定config.ini配置文件的目录。该配置文件中保存用于接入http链接的服务器配置http-server-address参数,以及其他用于资源共享的配置参数。
默认情况下,keosd将钱包文件保存在 ~/eosio-wallet 目录下,钱包文件名为:.wallet。例如,默认钱包文件名为 default.wallet。当建立了其他钱包后,在该目录下会分别建立每个钱包文件,例如当建立了一个名称为"duncanwang"的钱包,会生成一个钱包文件duncanwang.wallet。钱包文件可以通过命令行参数--data-dir存放在指定的目录中。
【预警】 从V1.0.5开始,发现要先运行keosd后在运行nodeos才可以创建钱包。
成功输出结果如下:

【问题】 关机后重新启动NODEOS,会有以下错误提示。
duncanwang@duncanwang:~/eos/build/programs/nodeos$ ./nodeos -e -p eosio --plugin eosio::wallet_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --replay-blockchain

1984049ms thread-0 main.cpp:123 main ] database dirty flag set (likely due to unclean shutdown): replay required
【解决方法】 进入'~/.local/share/eosio/nodeos' 目录,删除data文件夹。 重新运行即可成功。
duncanwang@duncanwang:~/eos/build/programs/nodeos$ cd ~/.local/share/eosio/nodeos
duncanwang@duncanwang:~/.local/share/eosio/nodeos$ ls
config data
duncanwang@duncanwang:~/.local/share/eosio/nodeos$ rm -r -f data
2) 启动私链 在新的命令行窗口输入以下命令。
cd ~/eos/build/programs/nodeos ./nodeos -e -p eosio --plugin eosio::wallet_plugin --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --replay-blockchain
参数说明:
1) -e
enable-stale-production,开启后,即使链过时了,也能产生区块
2) -p eosio
producer-name,生产者的名字,这里指定为eosio
3) --plugin eosio::wallet_plugin
在启动 nodeos
时,需要添加参数 eosio::wallet_plugin
,否则的话,每次节点重启,之前创建的钱包,账号都不会加载进来。
4)--plugin eosio::chain_api_plugin
5) --plugin eosio::history_api_plugin
记录执行过程。
7) --replay-blockchain
--replay-blockchain
表示清除数据库内链的状态,重新运行,它会导致重新启动时先读取之前的区块进行加载。
【注意】 节点关闭后,钱包将会被加锁。重新启动 nodeos
后,需要使用 open
命令打开钱包,然后使用 unlock
命令解锁钱包。
例如:
duncanwang@duncanwang:~/eos$ cleos wallet unlock -n duncanwang
password: Unlocked: duncanwang
输入nodes -help可以看到所有参数的帮助说明。
duncanwang@duncanwang:~/eos$ nodeos -help

cleos wallet create -n duncanwang
创建 duncanwang
钱包成功,输出结果如下:
duncanwang@duncanwang:~/eos$ cleos wallet create -n duncanwang
Creating wallet: duncanwang
Save password to use in the future to unlock this wallet.
Without password imported keys will not be retrievable.
"PW5JMZdES2Cds5LsPRUBRo2THEXpbFSM17Xmcd2XWG7XBd49wveTo"
【结果确认】
duncanwang@duncanwang:~$ cleos wallet list
Wallets:
[
"duncanwang *"
]
duanwang
钱包已存在了,*表示该账号已解锁。
【问题1】 创建钱包重名,但是cleos wallet list看不到
duncanwang@duncanwang:~$ cleos wallet create -n duncanwang
Error 3120001: Wallet already exists
Try to use different wallet name.
【解决方法】
这个主要是运行的命令中没有导入钱包 --plugin eosio::wallet_plugin
这个参数,导致已创建钱包未加载,但是目录下存在已创建的钱包文件。
./nodeos -e -p eosio --plugin eosio::chain_api_plugin --plugin eosio::history_api_plugin --replay-blockchain
~/eosio-wallet 目录下删除文件duncanwang.wallet即可重新创建。
【问题2】重启节点后,cleos wallet list发现已创建的钱包等不存在。
duncanwang@duncanwang:~$ cleos wallet list
Wallets:
[
]
【解决方法】 运行./nodeos命令时要带参数--plugin eosio::wallet_plugin 【解决方法2】 后来发现这种方法有时也是不可行,cleos wallet list没有看到钱包。 采用命令'cleos wallet open -n duncanwang'打开钱包后,就正常加载进来了。
【问题3】创建钱包时提示keosd已运行,并且无法连接
duncanwang@duncanwang:~$ cleos wallet create -n duncanwang
"/usr/local/bin/keosd" launched
Unable to connect to keosd, if keosd is running please kill the process and try again.
【解决方法】 需要输入以下命令把keosd重启下。
ps -ef | grep keosd kill -9 pid keosd --http-server-address=127.0.0.1:8900
操作实例如下:
duncanwang@duncanwang:~$ ps -ef | grep keosd
duncanw+ 2439 1 0 07:14 pts/1 00:00:00 /usr/local/bin/keosd --http-server-address=::1:8900
duncanw+ 2441 2389 0 07:16 pts/1 00:00:00 grep --color=auto keosd
duncanwang@duncanwang:~$ kill -9 2439
1) 找到eosio的系统账号的默认公钥/私钥对 找到配置文件,例如以下地址,~/.local/share/eosio/nodeosconfig 的 config.ini,默认的私钥/公钥是一样的。
#signature-provider = EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV=KEY:5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3
2),钱包导入系统账号私钥
cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3 -n duncanwang
duncanwang@duncanwang:~/eos$ cleos wallet import 5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3 -n duncanwang
imported private key for: EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV
3),查看系统账号信息 以下命令可以查看eosio系统账号的密钥和资源占用情况。
cleos get account eosio
duncanwang@duncanwang:~/eos/build$ cleos get account eosio

现在我们有一个钱包,并且加载了eosio帐户的密钥,我们可以设置一个默认的系统合约。为了开发的目的,可以使用默认的eosio.bios合约。通过此合约,您可以直接控制其他帐户的资源分配,并调用其他特权API。在公开区块链中,这个系统合约将管理其他账户的 token 抵押和解抵押操作,以为合约执行预留CPU、网络活动带宽,以及预留内存。 eosio.bios合约可以在你的EOSIO源代码文件夹中找到:contracts/eosio.bios。下面的命令序列,都假定是在EOSIO源代码的根目录执行。但是您可以通过指定完整路径,从任意位置执行这个命令:${EOSIO_SOURCE}/build/contracts/eosio.bios。
这个命令序列的结果是,cleos发起一个包含两个操作(actions)的交易(transaction):eosio::setcode和eosio::setabi。
代码定义了合约如何运行,abi描述了参数如何在二进制和json表示之间进行转换。虽然abi在技术上是可选的,但为了便于使用,所有的EOSIO工具都依赖于它。
输入命令:
cleos set contract eosio build/contracts/eosio.bios -p eosio
输出结果,表示本地执行成功。

创建账号的命令: cleos create account eosio {new_account} ownerkey {active_key}
其中eosio是超级用户,需要靠超级用户来创建其它的新用户,eosio后面就是你的新用户的用户名。
除了新的账号之外,命令后面还有两个key: 1、Owner key 2、Active key
Owner key是什么意思呢?Owner key表示分配给新账号的一个Owner认证的公钥。Active key是分配给新账号一个Active认证的一个公钥。
至于这两个认证,我后面会给详细介绍,这是两个主要的权限。我创建一个账号,如果这个账号要有Owner的权限和Active的权限,就必须要用这两个key才能实现。 我们来总结一下刚才的操作,我们刚才操作是调用cleos create account创建了一个账号,这个账号的命名规则遵守下边两个规则: 1、小于13个字符; 2、仅包含这些字符:.12345abcdefghijklmnopqrstuvwxyz 另外,刚才给大家说到Owner key和Active key的概念。Owner key的概念就是你账号的所有控制权限,你只要有了Owner key,你可以对这个账号的任何东西做任何的事儿,这是它的所有控制权。 而Active key只掌握了你的账号资金的访问权限,也就是你如果有了Active这个权限的话,你可以对这个账号的资金进行转移,但是你不能转移这个账号的所有权,或者不能做超过这个Active权限其它的权利。 如果简单的理解,Owner key就是对这个账号的最高权限,Active只是用来转移资金而已。这也是与以太坊智能合约开发的一个区别,以太坊账号的权限其实没有这么细分,它就只有一个账号,我只要有这个账号的公钥和私钥,我就可以做任何事情。 具体操作如下。
cleos create account eosio wangdenghui1 EOS6EHAzvrpQ4wo1BPcAk86X6aGDARZgqTcAq1mJRF1SxEYgNGWN1 EOS6EHAzvrpQ4wo1BPcAk86X6aGDARZgqTcAq1mJRF1SxEYgNGWN1
