btcpool 编译安装，以及ETH私池搭建

部署条件

部署系统： ubuntu 18.04

矿池交互图

编译源代码

git clone https://github.com/btccom/btcpool.git

安装依赖

sudo apt-get update
sudo apt-get install -y git build-essential autotools-dev libtool autoconf automake pkg-config cmake \
                   openssl libssl-dev libcurl4-openssl-dev libconfig++-dev \
                   libboost-all-dev libgmp-dev libmysqlclient-dev libzookeeper-mt-dev \
                   libzmq3-dev libgoogle-glog-dev libhiredis-dev zlib1g zlib1g-dev \
                   libsodium-dev libprotobuf-dev protobuf-compiler

注意：不再建议libevent-dev从软件源安装。 libevent的发行版和稳定版本将在sserver中导致死锁错误（问题＃75）。建议您使用下面的命令从它的master分支手动构建libevent。

有时一个或两个软件包由于依赖关系问题而失败，您可以尝试aptitude

sudo apt-get update
sudo apt-get install -y aptitude
sudo aptitude install git build-essential autotools-dev libtool autoconf automake pkg-config cmake \
                   openssl libssl-dev libcurl4-openssl-dev libconfig++-dev \
                   libboost-all-dev libgmp-dev libmysqlclient-dev libzookeeper-mt-dev \
                   libzmq3-dev libgoogle-glog-dev libhiredis-dev zlib1g zlib1g-dev \
                   libsodium-dev libprotobuf-dev protobuf-compiler
# Input `n` if the solution is `NOT INSTALL` some package.
# Eventually aptitude will give a solution that downgrade some packages to allow all packages to be installed.

安装ZooKeeper

安装依赖

sudo apt-get install -y zookeeper zookeeper-bin zookeeperd

创建所需目录

mkdir -p /data/work/zookeeper
mkdir /data/work/zookeeper/version-2
touch /data/work/zookeeper/myid
sudo chown -R zookeeper:zookeeper /data/work/zookeeper

设置机器id

sudo echo 1 > /data/work/zookeeper/myid

修改配置

sudo vim /etc/zookeeper/conf/zoo.cfg

initLimit=5
syncLimit=2
clientPort=2181
clientPortAddress=127.0.0.1
dataDir=/data/work/zookeeper
#伪分布式
server.1=127.0.0.1:2888:3888

启动服务

#start/stop service
sudo service zookeeper restart
#service zookeeper start/stop/restart/status

安装Kafka

安装依赖

sudo apt-get install -y default-jre

安装java 1.8

sudo apt-get update
sudo apt-get install openjdk-8-jdk
update-alternatives --display java
sudo update-alternatives --config java
java -version

安装kafka

mkdir -p /data/work/kafka
cd /data/work/kafka
wget https://archive.apache.org/dist/kafka/0.11.0.2/kafka_2.11-0.11.0.2.tgz
tar -zxf ./kafka_2.11-0.11.0.2.tgz --strip 1

编辑配置

vim /data/work/kafka/config/server.properties

broker.id=1
offsets.topic.replication.factor=1
message.max.bytes=20000000
replica.fetch.max.bytes=30000000
log.dirs=/data/work/kafka-logs
listeners=PLAINTEXT://127.0.0.1:9092
#伪分布式
zookeeper.connect=127.0.0.1:2181
#start server
cd /data/work/kafka
nohup /data/work/kafka/bin/kafka-server-start.sh /data/work/kafka/config/server.properties > /dev/null 2>&1 &

遇到问题

yw_manager@web204_234:/data/work/kafka$ /data/work/kafka/bin/kafka-server-start.sh /data/work/kafka/config/server.properties

解决方案

降级java 1.8

从其master分支构建libevent

注意：版本2.1.9-beta之前的libevent将在sserver中导致死锁错误（问题＃75）。请使用release-2.1.9-beta和更高版本。

wget https://github.com/libevent/libevent/releases/download/release-2.1.10-stable/libevent-2.1.10-stable.tar.gz
tar zxf libevent-2.1.10-stable.tar.gz
cd libevent-2.1.10-stable
./autogen.sh
./configure --disable-shared
make -j$(nproc) && sudo make install
编译librdkafka-v0.9.1
wget https://github.com/edenhill/librdkafka/archive/0.9.1.tar.gz
tar zxvf 0.9.1.tar.gz
cd librdkafka-0.9.1
./configure && make -j$(nproc) && sudo make install

# if you want to keep static libraries only
sudo rm -v /usr/local/lib/librdkafka*.so /usr/local/lib/librdkafka*.so.*

下载Bitcoin源码，并建立链接到BTCPool

支持ETH的矿池用BTC选项

mkdir work
sudo mv work/ /data/
cd /data/work

wget -O bitcoin-0.16.0.tar.gz https://github.com/bitcoin/bitcoin/archive/v0.16.0.tar.gz
tar zxf bitcoin-0.16.0.tar.gz

git clone https://github.com/btccom/btcpool.git
cd btcpool
mkdir build
cd build

# Release build:
cmake -DJOBS=4 -DCHAIN_TYPE=BTC -DCHAIN_SRC_ROOT=/data/work/bitcoin-0.16.0 ..
make -j$(nproc)

# Debug build:
cmake -DCMAKE_BUILD_TYPE=Debug -DCHAIN_TYPE=BTC -DCHAIN_SRC_ROOT=/data/work/bitcoin-0.16.0 ..
make -j$(nproc)
常见问题

使用当前最新版本bitcoin v0.21.0提示如下错误，暂时未跟进该问题，先用v0.16.0版本测试

CMake Error at CMakeLists.txt:267 (message):
  /data/work/bitcoin-0.21.0/src/crypto/libbitcoin_crypto.a not exists!

估计是本地已安装boost版本问题，本项目依赖boost v1.65，删除本地已安装boost，重新运行第一步，安装依赖

/usr/local/include/boost/thread/pthread/condition_variable.hpp:131: undefined reference to `boost::this_thread::interruption_point()'
collect2: error: ld returned 1 exit status
