此水龙头代码在石墨烯水龙头源码（https://github.com/cryptonomex/faucet ）上修改，指南示例在DigitalOcean 的 ubuntu 16.04 服务器上测试正常。ubuntu 18.04、更高版本ruby，甚至相同配置下的vultr服务器均有各种报错，欢迎填坑。
此使用SEER测试网络，若有需要，请更换为主网。
新建一个screen，命名为seer。
screen -S seer新建一个目录，命名为seer。
mkdir seer下载最新版本SEER命令行钱包到seer目录，并重命名为seer.tar.gz，示例中的版本是0.0.4，请替换为最新版。
curl -Lo seer/seer.tar.gz https://github.com/seer-project/seer-core-package/releases/download/v0.04/seer-ubuntu-0.0.4.tar.gz进入seer目录
cd seer解压缩seer.tar.gz
tar xzvf seer.tar.gz启动命令行钱包，此例中的chain-id为测试网络，通过任意命令行钱包输入info指令获取，默认为主网chain-id，-s参数为钱包连接的节点api，此处为测试网络公告api节点，-r参数为钱包暴露的websocket RPC端口，水龙头程序即是通过此端口控制命令行钱包进行操作， -H为钱包暴露的HTTP RPC端口，所有端口都可以自行修改。
./cli_wallet --chain-id="da68a9c5f2fd9ed48e626ea301db1c77505523884ba0dd409e779246c6ea26cf" -s ws://123.206.78.97:8002 -r 127.0.0.1:9991 -H 127.0.0.1:9992以上指令可以复制以下命令粘贴至终端，一次性执行：
screen -S seer mkdir seer curl -Lo seer/seer.tar.gz https://github.com/seer-project/seer-core-package/releases/download/v0.04/seer-ubuntu-0.0.4.tar.gz cd seer tar xzvf seer.tar.gz ./cli_wallet --chain-id="da68a9c5f2fd9ed48e626ea301db1c77505523884ba0dd409e779246c6ea26cf" -s ws://123.206.78.97:8002 -r 127.0.0.1:9991 -H 127.0.0.1:9992钱包启动后，先设置钱包解锁密码，123替换为你想设置的密码
set_password 123解锁钱包
unlock 123导入账号资金私钥
import_key okok 5JkbV8aTaYRVaarTUJQ9Y56cr4QajxNFfCoQj6Q9JFL8XvUZ5CQ import_key else 5KiSC6rRAEkTj72fg3G3zF8RHmCEgZw7aSXBjKqDfvY2XN1qvyd以上指令可以复制以下命令粘贴至终端，一次性执行：
set_password 123 unlock 123 import_key okok 5JkbV8aTaYRVaarTUJQ9Y56cr4QajxNFfCoQj6Q9JFL8XvUZ5CQ import_key else 5KiSC6rRAEkTj72fg3G3zF8RHmCEgZw7aSXBjKqDfvY2XN1qvyd钱包需要在unlocked状态，才能被水龙头调用。
钱包连接正常的显示：
