bitshares研究系列【水龙头（faucet）完整安装】
刚接触bitshares的时候，就听有人说起“水龙头”这个玩意，后来知道这是注册帐号的一个中心化服务，英文名叫faucet，而且是用Ruby写的，不熟悉Ruby就更不想理它了，最近有些需要还是得研究下这个“水龙头”与咱家的水龙头有什么不一样！
Mac下安装
按官网文档和faucet下的README.md一步步安装吧
mysql
mysql在我机器上应该都已安装好了，下面这行就不执行了。
sudo apt-get install mysql-server libmysqlclient-dev
# put a master password for mysql
Ruby
Faucet是用Ruby语言编写的，所以要安装Ruby工具。
Ruby基本没接触过，一会看看代码再评估，不过我相信它没有Erlang难！
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc

sudo rbenv install 2.2.3
sudo rbenv global 2.2.3
sudo gem install bundler
faucet源代码
git clone https://github.com/cryptonomex/faucet
cd faucet
sudo bundle # ignore warnings
不过我执行时出错了：
bash-3.2$ sudo bundle
Don't run Bundler as root. Bundler can ask for sudo if it is needed, and installing your bundle as root will break
this application for all non-root users on this machine.
Your Gemfile lists the gem devise (>= 0) more than once.
You should probably keep only one of them.
While it's not a problem now, it could cause errors if you change the version of one of them later.

-----
The file "/usr/include/iconv.h" is missing in your build environment,
which means you haven't installed Xcode Command Line Tools properly.
To install Command Line Tools, try running `xcode-select --install` on
terminal and follow the instructions. If it fails, open Xcode.app,
select from the menu "Xcode" - "Open Developer Tool" - "More Developer
Tools" to open the developer site, download the installer for your OS
version and run it.

*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.

An error occurred while installing nokogiri (1.6.6.2), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.6.2'` succeeds before bundling.
In Gemfile:

nokogiri
说没安装啥就安装一遍：
xcode command line developer tools
bash-3.2$ xcode-select --install
xcode-select: note: install requested for command line developer tools
下面这个安装得等developer tools安装完。
bash-3.2$ sudo gem install nokogiri -v '1.6.6.2'
换了个错误，如下：
checking for xmlParseDoc() in libxml/parser.h... no
checking for xmlParseDoc() in -lxml2... no
checking for xmlParseDoc() in -llibxml2... no
-----
libxml2 is missing. Please locate mkmf.log to investigate how it is failing.
-----
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
尝试以下方法解决：
bash-3.2$ gem uninstall nokogiri
bash-3.2$ brew install libxml2 libxslt libiconv
bash-3.2$ sudo NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"
bash-3.2$ sudo gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include/libxml2 --use-system-libraries
bash-3.2$ sudo ARCHFLAGS="-arch x86_64" gem install nokogiri
bash-3.2$ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri
这上面不确定哪步是正确的，也许都可以，重要的是要把bundle这个命令改成如下：
bash-3.2$ sudo bundle config build.nokogiri --use-system-libraries
bash-3.2$ sudo bundle install
这次执行成功，结果如下：
Bundle complete! 26 Gemfile dependencies, 77 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
配置
faucet.yml
cp config/faucet-example.yml config/faucet.yml
vim config/faucet.yml
cli_wallet_connection: ws://127.0.0.1:8098
registrar_account: barnard
referrer_percent: 50
refcode_prefix: F01
default_url: localhost
default_port: 3000
exception_notification:
sender_address: [email protected]
exception_recipients: [email protected]
smtp:
address: address
user_name: user
password: password
从这个配置文件可以看出，faucet也是连接cli_wallet，还记得在bitshares研究系列【私链运行】中已经设置了可正常运行的私链，并且把barnard这个帐号提升到了永久会员，那就把barnard设为registrar_account吧！怎么看会员是永久会员，如下：
get_account barnard
{
"id": "1.2.18",
"membership_expiration_date": "1969-12-31T23:59:59",
...
}
如果会员过期时间是"1969-12-31T23:59:59"就是永久会员了！
secrets.yml
cp config/secrets-example.yml config/secrets.yml
rake secret
vim config/secrets.yml
这一步出错了，提示mysql版本不对，只是密钥设置，测试运行暂时不管，就用缺省的好了！
# Be sure to restart your server when you modify this file.
# Your secret key is used for verifying the integrity of signed cookies.
# If you change this key, all old signed cookies will become invalid!

我机器上mysql用户root的密码就是空，就不用设置了！
刚才不想解决的mysql版本问题，果真还是躲不过！哎~
Bundler::GemRequireError: There was an error while trying to load the gem 'mysql2'.
Gem Load Error is: Incorrect MySQL client library version! This gem was compiled for 5.5.37 but the client library is 5.6.10.
看一下当前mysql版本：
bash-3.2$ mysql -V
mysql Ver 14.14 Distrib 5.5.37, for osx10.6 (i386) using readline 5.1
此处跳过mysql版本解决方案，因为我也不确定哪个步骤解决的，可能问题是gem mysql库，此处不影响文章主题，不深究了~
gem uninstall mysql2
gem install mysql2 -v '0.3.18'

看起来这个操作与graphene websocket还有通信，还建了一些表和索引，去mysql看看：
mysql> show databases;
+-----------------------+
| Database |
+-----------------------+
| information_schema |
| bitcoin |
| bitshares_faucet_dev |
| bitshares_faucet_test |
| ethaddr |
| mysql |
| performance_schema |
| sys |
+-----------------------+
8 rows in set (0.00 sec)
多了两个bitshares_xxx的库，这个在database.yml中指定的。
简单看下有哪些表：
mysql> use bitshares_faucet_dev
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
mysql> show tables;
+--------------------------------+
| Tables_in_bitshares_faucet_dev |
+--------------------------------+
| assets |
| bts_accounts |
| identities |
| referral_codes |
| schema_migrations |
| user_actions |
| users |
| widgets |
+--------------------------------+
8 rows in set (0.00 sec)
表里数据就先不列出来了，大概就是资产、帐号相关的，后期看看faucet都用来干嘛。
继续执行：
bash-3.2$ RAILS_ENV=production bundle exec rake db:create db:schema:load
运行
rails s
rails命令，即使安装以后也一直错误提示：
bash-3.2$ rails
Rails is not currently installed on this system. To get the latest version, simply type:
$ sudo gem install rails
You can then rerun your "rails" command.
这个其实解决很简单，安装rails后要重启终端，无语~ 不熟悉的环境就得付出不少时间代价！
再次启动，成功了，如下：
bash-3.2$ rails s

这次需要指定 --rpc-endpoint=127.0.0.1:8098，这个与faucet.yml中配置
全部准备就绪后，运行浏览器：http://localhost:8080/ 进入本地私链网页钱包，设置节点为ws://127.0.0.1:8090，设置水龙头为 http://127.0.0.1:3000 ，进入注册帐号页面，注册帐号出现错误：
!!! register_account error: {"code"=>1, "message"=>"Assert Exception: base58str.substr( 0, prefix_len ) == prefix: ", "data"=>{"code"=>10, "name"=>"assert_exception", "message"=>"Assert Exception", "stack"=>[{"context"=>{"level"=>"error", "file"=>"types.cpp", "line"=>49, "method"=>"public_key_type", "hostname"=>"", "thread_name"=>"th_a", "timestamp"=>"2018-04-29T12:01:45"}, "format"=>"base58str.substr( 0, prefix_len ) == prefix: ", "data"=>{"base58str"=>"GPH4yM6i9Y3bpnrpBpUPWX3HK7ZbvEymXibr96re8ZghxRzU6fWdu"}}, {"context"=>{"level"=>"warn", "file"=>"websocket_api.cpp", "line"=>125, "method"=>"on_message", "hostname"=>"", "thread_name"=>"th_a", "timestamp"=>"2018-04-29T12:01:45"}, "format"=>"", "data"=>{"call.method"=>"call", "call.params"=>[0, "register_account", ["barnard18", "GPH4yM6i9Y3bpnrpBpUPWX3HK7ZbvEymXibr96re8ZghxRzU6fWdu", "GPH7RfCPdSYRb6DGBJu4YbHUx4EBn94QFoYZEiGa2rZ4rVyJfWa3w", "barnard", "barnard", 0, true]]}}]}}
为什么这里的密钥是"GPHxxx"呢？好像bitshares-core生成时是“BTSxxx”，也找到对应代码在ChainConfig.js里：
var ecc_config = {
address_prefix: process.env.npm_config__graphene_ecc_default_address_prefix || "GPH"
};
可是...process.env.npm_config__graphene_ecc_default_address_prefix 我就是不会设，如果是个环境变量的话还不秒解决啊！硬是没设成。。。
不过我找到一个变通的方法，下面有个setPrefix()的方法可以设前缀，既然这样找找有哪个文件引用了bitsharesjs-ws这个库，很容易在api/accountApi.js中找到，也正是处理帐号的api，好吧，就先在这加着试试，加入以下代码：
import {ChainConfig} from "bitsharesjs-ws";
ChainConfig.setPrefix("BTS");
刷新页面，重新注册，这次faucet显示成功了！

本地钱包显示注册成功界面
折腾这么大半天就注册一个帐号太不值了，再注册一个！发现没法用水龙头提供的帐户免费注册了，一旦你浏览器已经注册过一个帐号，这个信息就记录在浏览器中，再注册新帐号会让你选择用哪个帐号付费！很简单，清浏览器缓存或者换个浏览器，我决定换个safari再注册个帐号"barnard002"！
这次很容易就注册成功了，我们看看注册这"barnard002"帐号前后barnard帐号的余额变化：
unlocked >>> list_account_balances barnard
list_account_balances barnard
1999979994.85450 BTS
unlocked >>> list_account_balances barnard
list_account_balances barnard
1999979989.70900 BTS
注册这个帐号，注册人成功花了5个BTS！
bitshares注册帐号是必须有注册人的，我们平时在bitshares上注册帐号没有看到注册人，其实注册人就是"水龙头"内置的帐户（registrar_account）。
结论
个人觉得faucet装一下比较容易，但是要真正在私链上能注册用户还是很麻烦的，好几个前题条件：bitshares节点运行在私链上、bitshares-ui正常运行、cli_wallet正常运行、faucet正常运行，而这几个东西的开发语言有c/c++、nodejs、ruby，运行环境也不一样，然后就是把这四大块联合起来，才能完成帐号的注册。
bitshares帐号注册流程：bitshares-ui钱包 ==> faucet(rpc) ==> cli_wallet ==> bitshares-core
本想一篇文章把faucet分析完的，结果安装花了这么多时间和文字说明，faucet的代码分析只能下回分解了！
