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

编译好的64位CentOS7.x适用的xmr-stak程序(已删除2%开发者费率设置)已上传至CSDN资源:

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

[root@seafile bin]# ./xmr-stak

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:
