In continuing our crypto series with xmr-stak we update the old article How to compile xmr-stak (2.4.5) under CentOS 7 for CPU mining cryptocurrencies with the new version 2.5 and tested the build procedure with the old CentOS 6.
In crypto mining it is important to have latest version of the mining software, because crypto world is super dynamic with thousands crypto currency and tens of algos, which ever month might be changed and updated!
Thanks to xmr-stak we can have one application capable of mining many different cryptocurrencies based on different algorithms. XMR-STAK is GPU and CPU miner, here we present only the CPU ability. Here are the steps you should do to install (in fact install dependencies and compile the miner) and to begin CPU mining:
STEP 1) Update your system and install the following dependencies
Because xmr-stak need a newer version of GNU GCC than the CentOS ships with you must install GNU GCC 5.1 at least. Because the latest versions have better optimizations for the processors we use here GNU GCC 7 from Software Collection repository – more information for this repository here: How to install new gcc and development tools under CentOS 7
[root@srv ~]# yum update -y [root@srv ~]# yum install -y centos-release-scl epel-release [root@srv ~]# yum install -y cmake3 devtoolset-7-gcc* hwloc-devel libmicrohttpd-devel openssl openssl-devel make git screen
STEP 2) Compile the mining program xmr-stak
[root@srv ~]# scl enable devtoolset-7 bash
