从什么时候开始流行CPU挖矿了？记得以前不都是用GPU吗？原来现在虚拟币的种类已经这么多了！大概研究了一下，目前CPU算力有优势的有这么几种虚拟币,貌似还都是匿名币
ZEC(零币)算法 Equihash 目前市场价格4000+
XMR(门罗币) 算法CryptoNight 目前价格4000+
BCN(字节币?) 算法CryptNote 目前价格 几分...
近期公司有几台机器被种了挖矿***，清除之余研究了一下有关CPU挖矿的工具，发现了 xmr-stak-cpu 这个东西
上网搜了搜，找到了GITHUB上的主页，好像刚升级不久
https://github.com/fireice-uk/xmr-stak
还有个早先点的版本地址为：https://github.com/fireice-uk/xmr-stak-cpu
找了一台测试机安装一下试试：
# git clone https://github.com/fireice-uk/xmr-stak # cd xmr-stak/ # ls CI CMakeLists.txt CONTRIBUTING.md doc Dockerfile LICENSE README.md scripts THIRD-PARTY-LICENSES xmrstak 好像没有可以执行的文件，不过我发现了Dockerfile，然后又在 scripts文件夹里找到了build_xmr-stak_docker.sh 难道是自动创建一个docker 来挖矿？打开来看看 # vim scripts/build_xmr-stak_docker/build_xmr-stak_docker.sh #!/bin/bash -uex if [[ $EUID -ne 0 ]]; then echo "This script must be run as root" exit 1 fi if [ -d xmr-stak ]; then git -C xmr-stak clean -fd else git clone https://github.com/fireice-uk/xmr-stak.git fi wget -c https://developer.nvidia.com/compute/cuda/9.0/Prod/local_installers/cuda_9.0.176_384.81_linux-run chmod a+x cuda_*_linux-run ######################## # Fedora 27 ######################## # CUDA is not going to work on Fedora 27 beacuse it's only support these distributions: http://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html docker run --rm -it -v $PWD:/mnt fedora:27 /bin/bash -c " set -x ; dnf install -y -q cmake gcc-c++ hwloc-devel libmicrohttpd-devel libstdc++-static make openssl-devel; cd /mnt/xmr-stak ; cmake -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF . ; make ; " test -d fedora_27 || mkdir fedora_27 mv xmr-stak/bin/* fedora_27 git -C xmr-stak clean -fd ######################## # Ubuntu (17.04) ######################## docker run --rm -it -v $PWD:/mnt ubuntu:17.04 /bin/bash -c " set -x ; apt update -qq ; apt install -y -qq libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev ; cd /mnt/xmr-stak ; /mnt/cuda_*_linux-run --silent --toolkit ; cmake -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF . ; ... 呵呵，果然不出所料，这个脚本针对 CentOS 和 Ubuntu系列linux系统自动创建建立一个Docker镜像然后安装xmr-stak 编辑一下这个脚本，只留下一个操作系统，我这里只留下了 Ubuntu 17部分 原来的脚本是跑完了docker 安装完成就吧容器删掉，而我现在想把这个容器留下于是就改了改，最后变成下面这个样子 #!/bin/bash -uex if [[ $EUID -ne 0 ]]; then echo "This script must be run as root" exit 1 fi if [ -d xmr-stak ]; then git -C xmr-stak clean -fd else git clone https://github.com/fireice-uk/xmr-stak.git fi ######################## # Ubuntu (17.04) ######################## docker run -itd --name "xmr" -v $PWD:/mnt ubuntu:17.04 /bin/bash docker exec -it "xmr" /bin/bash -c " set -x ; apt update -qq apt install -y -qq libmicrohttpd-dev libssl-dev cmake build-essential libhwloc-dev ; cd /mnt/xmr-stak ; cmake -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF . ; make install; "
我的linux 不需要CUDA 删掉 CUDA部分的代码
直接执行(运行前请确定是否已经安装Docker)

终止进程后发现，bin下面多了两个文件 cpu.txt 和 config.txt
# ls config.txt cpu.txt libxmr-stak-backend.a libxmr-stak-c.a xmr-stak
打开来看看
# vim config.txt
/*
* pool_address - Pool address should be in the form "pool.supportxmr.com:3333". Only stratum pools are supported.
* wallet_address - Your wallet, or pool login.
* pool_password - Can be empty in most cases or "x".
* use_nicehash - Limit the nonce to 3 bytes as required by nicehash.
* use_tls - This option will make us connect using Transport Layer Security.
* tls_fingerprint - Server's SHA256 fingerprint. If this string is non-empty then we will check the server's cert against it.
* pool_weight - Pool weight is a number telling the miner how important the pool is. Miner will mine mostly at the pool
* with the highest weight, unless the pool fails. Weight must be an integer larger than 0.
*
* We feature pools up to 1MH/s. For a more complete list see M5M400's pool list at www.moneropools.com

cpu.txt是我们调整CPU使用效率的文件，如果觉得资源耗太多可以减少一些
好了，再次执行的时候就不用进行设置了
# nohup ./xmr-stak & [1] 714
看一下资源消耗，瞬间就上10了哈哈，看看这点算力和这么高的负载，咱们就测测就得了 hoho
