CentOS7安装xmr-stak挖矿门罗币
首先关闭CentOS的SELinux功能和防火墙
- #systemctl disable firewalld.service 禁用firewalld服务
- 修改 /etc/selinux/config 文件中的 SELINUX="disabled" ，然后重启。
配置网卡:
- 编辑/etc/sysconfig/network-scripts/网卡配置文件
- BOOTPROTO=static
- ONBOOT=yes
- IPADDR=xxx
- NETMASK=xxx
- GATEWAY=xxx
- 编辑/etc/resolve.conf
- nameserver 114.114.114.114
编译和安装xmr-stak,cmake3命令后面的参数声明只使用CPU进行挖矿
- yum install -y centos-release-scl epel-release
- yum install -y cmake3 devtoolset-4-gcc* hwloc-devel libmicrohttpd-devel openssl-devel make git
- scl enable devtoolset-4 bash
- git clone https://github.com/fireice-uk/xmr-stak.git
注意,从github上克隆完成后,要修改一下默认的作者抽费率的设置,否则默认的作者要从你挖的结果中抽掉2%,修改文件xmr-stak/xmrstak/donate-level.hpp中默认的2.0改为0.0
- constexpr double fDevDonationLevel = 0.0 / 100.0;
继续下面的编译操作
- mkdir xmr-stak/build
- cd xmr-stak/build
- cmake3 -DCUDA_ENABLE=OFF -DOpenCL_ENABLE=OFF ..
- make install
PS:对于不需要编译直接拷过来xmr-stak用的话,只需要安装以下包即可
- hwloc-devel libmicrohttpd-devel openssl-devel

编写后台运行的脚本:
- #vi /opt/runXMR.sh
- 添加内容如下:
- cd /opt/bin
- nohup /opt/bin/xmr-stak >/dev/null 2>&1 &
- 自行修改上面的具体程序位置
运行./xmr-stak根据向导提示录入相关配置信息

这里我设置了使用666端口运行web服务,可以远程查看当前的挖矿状态,矿池用的是皮皮虾,一个国内的,速度不错,先挖挖试试吧,网站地址:https://xmr.c1d2.com,矿池分了好几个,可以根据自己机器性能来选,我这台垃圾虚拟机,就用最low的矿池了,地址mine.ppxxmr.com:3333,其他矿池地址:
这样就开始挖矿了,但是上面出现了有个内存分配的错误
- MEMORY ALLOC FAILED: mmap failed
还需要设置一下系统的参数
- [root@seafile bin]# vi /etc/security/limits.conf
增加内容:
* soft memlock 262144
* hard memlock 262144
再执行
- # sysctl -w vm.nr_hugepages=128
再运行xmr-stak就不再提示内存的报错了
这时候本地打开浏览器访问服务器的地址:666就可以看到当前的挖矿状态:
