本文将以dash（x11）和Raven（x16rv2)为例子来说明多算法矿池的搭建过程。
1 环境准备
1.1 准备Ubuntu
准备虚拟机或物理机，操作系统为Ubuntu 16.04
1.2 安装必需的包
sudo apt-get install build-essential libtool autotools-dev autoconf pkg-config libssl-dev libboost-all-dev sudo apt-get install git npm nodejs redis-server1.3 下载源码
git clone https://github.com/zone117x/node-open-mining-portal.git nomp
cd nomp
npm update
执行完update后会编译更新一系列依赖库
2 配置矿池
这里钱包和矿池服务器分别部署在不同的机器上，当然它们也可以部署到同一台机器上。
2.1 服务器端配置
cp config_example.json config.json
config.json内容如下

109 "useCryptsy": true,
110 "useMintpal": true,
111 "useBittrex": true
112 }
113 }
config.json
其中34行改为Ubuntu主机IP地址，为了防止80端口被其他web服务占用，这里使用8080端口，见35行，36行是stratum协议域名，即矿池部署服务器绑定的域名，这里保持默认，其实这里也应是Ubutu主机IP地址，之后再生成两个算法的配置文件
cp pool_configs/litecoin_example.json pool_configs/dash.json
cp pool_configs/litecoin_example.json pool_configs/raven.json
两个文件内容如下
1 {

dash.json
其中第5行的address必须为有效的地址，第6行的daemon里分别填写的是钱包运行主机的IP地址，端口号，配置文件里的用户名和密码，如图所示

raven.json
Raven配置和Dash类似，钱包的配置文件内容如下
另外在coins目录下还需要准备两个币种的算法配置文件darkcoin.json和raven.json文件，内容如下：
1 {
2 "name": "Darkcoin",
3 "symbol": "DRK",
4 "algorithm": "x11",
5 "mposDiffMultiplier": 256
6 }
darkcoin
1 {
2 "name": "Raven",
3 "symbol": "RVN",
4 "algorithm": "x16rv2",
5 "txfee": 0.00005
6 }
raven
3 启动矿池并挖矿
运行如下命令启动矿池
sudo node init.js
矿池主界面如下所示
单击Getting Started可以看到该矿池支持Dash（Darkcoin）和Raven挖矿，再单击左侧的Raven可以看到x16rv2的stratum地址及端口，注意真正挖矿时需要用矿机部署的PC地址10.10.1.230替换cryppit.com
用开源代挖矿程序cpuminer-multi来验证搭建的矿池，编译后运行如下命令来进行挖矿
./cpuminer -a x16r -o stratum+tcp://10.10.1.230:7777 -u RVG96MbaKEDFzzj9NzbAuxkDt86KAm2Qj5 -p x -D -P -t 10
运行一段时间后可以看到后台软件相应的接收情况
矿池Graph Status显示如下
Dash挖矿验证过程类似，不再进行详细介绍。
