本指南介绍如何将Sentinel安装到Ubuntu 14.04 / 16.04中的现有Masternode上。
安装
1.安装先决条件
确保已安装Node v8.xx或更高版本：
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs sudo apt-get install -y build-essential libzmq3-dev
安装PM2：
# 1. Add the PM2 repository signing key sudo apt-key adv --keyserver keyserver.ubuntu.com --recv D1EA2D4C2. Add the PM2 repository
echo “deb http://apt.pm2.io/ubuntu stable main” | sudo tee /etc/apt/sources.list.d/pm2.list
3. Update list of available packages
sudo apt-get update
4. Install PM2
sudo apt-get install pm2
确保运行的本地GeekCash守护程序至少为1.0.1.2版（1000102）
geekcash-cli getinfo
2.安装Sentinel
克隆Sentinel存储库并安装节点包。
git clone https://github.com/geekcash/node-sentinel.git && cd node-sentinel
安装节点模块
npm i
如果出现这样的错误，请安装以下命令：
sudo apt-get install libboost-all-dev -y
> [email protected] install /root/node-sentinel/node_modules/zmq
> node-gyp rebuildTraceback (most recent call last):

3.创建config.js
cp -i config_example.js config.js
获取RPC用户和密码 .geekcash/geekcash.conf
cd …/
cat .geekcash/geekcash.conf
rpcuser=root
rpcpassword=pass
rpcport=6888
listen=1
server=1
daemon=1
logtimestamps=1
maxconnections=64
txindex=1
masternode=1
externalip=x.x.x.x:6889
masternodeprivkey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
编辑config.js
cd node-sentinel
nano config.js
version:‘1.2.1’,
coins: [
{
id: ‘MN-01’,
rpc: {
url: ‘http://127.0.0.1:6888/’,
method: ‘POST’,
auth: {
username: ‘root’,
password: ‘pass’
},
}
},
{
id: ‘MN-02’,
rpc: {
url: ‘http://127.0.0.1:6888/’,
method: ‘POST’,
auth: {
username: ‘root’,
password: ‘pass’
},
}
},
// {
// id: ‘MN-03’,
// rpc: {
// url: ‘http://127.0.0.1:6888/’,
// method: ‘POST’,
// auth: {
// username: ‘root’,
// password: ‘pass’
// },
// }
// },]
4.允许RPC IP
如果为多个masternode运行sentinel，则需要配置rpcallowip以允许sentinel连接到此MN并重新启动GeekCash守护程序。
rpcuser=root
rpcpassword=pass
rpcallowip=[IP of sentinel]
rpcport=6888
listen=1
server=1
daemon=1
logtimestamps=1
maxconnections=64
txindex=1
masternode=1
externalip=8.8.8.8:6889
masternodeprivkey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
例如：您的哨兵在IP：9.9.9.9，其他MN配置
rpcuser=root
rpcpassword=pass
rpcallowip=9.9.9.9
rpcport=6888
listen=1
server=1
daemon=1
logtimestamps=1
maxconnections=64
txindex=1
masternode=1
externalip=8.8.8.8:6889
masternodeprivkey=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
geekcash-cli stop
geekcashd
5.运行应用程序
pm2 start ./app.js --name sentinel
设置启动脚本
//使用您在服务器启动/重新启动时管理的进程重新启动PM2至关重要。要解决此问题，只需运行此命令即可生成活动的启动脚本：
pm2 startup
#geek-cash
