本文以 fireice-uk/xmr-stak-cpu v1.1 作為示範如何從編譯到執行

系統為Ubuntu 16.04 LTS server,選擇的礦池為 monerohash.com

若沒有要自行編譯檔案可以直接從編輯config.txt開始 (windows系統亦同)


sudo apt-get install aptitude

sudo aptitude update

sudo aptitude install –with-recommends build-essential autotools-dev autoconf automake libcurl3 libcurl4-gnutls-dev git make cmake libssl-dev pkg-config libevent-dev libunbound-dev libminiupnpc-dev doxygen supervisor jq libboost-all-dev htop libmicrohttpd-dev

git clone https://github.com/fireice-uk/xmr-stak-cpu.git

cd xmr-stak-cpu

nano donate-level.h (此步驟可自定給予作者的抽成後ctrl+x儲存)

cmake .


cp config.txt bin

cd bin

sudo sysctl -w vm.nr_hugepages=128

nano config.txt (編輯config.txt設定裡的執行緒數量與對應的核心,礦池網址與錢包地址後ctrl+x儲存)

screen (非桌面版Linux系統可選步驟)

sudo ./xmr-stak-cpu (linux系統以root執行,windows以系統管理員身分執行)


 * Number of threads. You can configure them below. Cryptonight uses 2MB of memory, so the optimal setting 
 * here is the size of your L3 cache divided by 2. Intel mid-to-high end desktop processors have 2MB of L3
 * cache per physical core. Low end cpus can have 1.5 or 1 MB while Xeons can have 2, 2.5 or 3MB per core.
"cpu_thread_num" : 7,

 * Thread configuration for each thread. Make sure it matches the number above.
 * low_power_mode - This mode will double the cache usage, and double the single thread performance. It will 
 *                  consume much less power (as less cores are working), but will max out at around 80-85% of 
 *                  the maximum performance.
 * no_prefetch -    This mode meant for large pages only. It will generate an error if running on slow memory
 *                  Some sytems can gain up to extra 5% here, but sometimes it will have no difference or make
 *                  things slower.
 * affine_to_cpu -  This can be either false (no affinity), or the CPU core number. Note that on hyperthreading 
 *                  systems it is better to assign threads to physical cores. On Windows this usually means selecting 
 *                  even or odd numbered cpu numbers. For Linux it will be usually the lower CPU numbers, so for a 4 
 *                  physical core CPU you should select cpu numbers 0-3.

 * Lare pages need a properly set up OS. It can be difficult if you are not used to systems administation,
 * but the performace results are worth the trouble - you will get around 20% boost. Slow memory mode is
 * meant as a backup, you won't get stellar results there. If you are running into trouble, especially
 * on Windows, please read the common issues in the README.
 * By default we will try to allocate large pages. This means you need to "Run As Administrator" on Windows.
 * You need to edit your system's group policies to enable locking large pages. Here are the steps from MSDN
 * 1. On the Start menu, click Run. In the Open box, type gpedit.msc.
 * 2. On the Local Group Policy Editor console, expand Computer Configuration, and then expand Windows Settings.
 * 3. Expand Security Settings, and then expand Local Policies.
 * 4. Select the User Rights Assignment folder.
 * 5. The policies will be displayed in the details pane.
 * 6. In the pane, double-click Lock pages in memory.
 * 7. In the Local Security Setting – Lock pages in memory dialog box, click Add User or Group.
 * 8. In the Select Users, Service Accounts, or Groups dialog box, add an account that you will run the miner on
 * 9. Reboot for change to take effect.
 * Windows also tends to fragment memory a lot. If you are running on a system with 4-8GB of RAM you might need
 * to switch off all the auto-start applications and reboot to have a large enough chunk of contiguous memory.
 * On Linux you will need to configure large page support "sudo sysctl -w vm.nr_hugepages=128" and increase your
 * ulimit -l. To do do this you need to add following lines to /etc/security/limits.conf - "* soft memlock 262144"
 * and "* hard memlock 262144". You can also do it Windows-style and simply run-as-root, but this is NOT
 * recommended for security reasons.
 * Memory locking means that the kernel can't swap out the page to disk - something that is unlikey to happen on a 
 * command line system that isn't starved of memory. I haven't observed any difference on a CLI Linux system between 
 * locked and unlocked memory. If that is your setup see option "no_mlck". 

 * use_slow_memory defines our behaviour with regards to large pages. There are three possible options here:
 * always  - Don't even try to use large pages. Always use slow memory.
 * warn    - We will try to use large pages, but fall back to slow memory if that fails.
 * no_mlck - This option is only relevant on Linux, where we can use large pages without locking memory.
 *           It will never use slow memory, but it won't attempt to mlock
 * never   - If we fail to allocate large pages we will print an error and exit.
"use_slow_memory" : "never",

 * 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".

 * Network timeouts.
 * Because of the way this client is written it doesn't need to constantly talk (keep-alive) to the server to make 
 * sure it is there. We detect a buggy / overloaded server by the call timeout. The default values will be ok for 
 * nearly all cases. If they aren't the pool has most likely overload issues. Low call timeout values are preferable -
 * long timeouts mean that we waste hashes on potentially stale jobs. Connection report will tell you how long the
 * server usually takes to process our calls.
 * call_timeout - How long should we wait for a response from the server before we assume it is dead and drop the connection.
 * retry_time    - How long should we wait before another connection attempt.
 *                Both values are in seconds.
"call_timeout" : 10,
"retry_time" : 10,

 * Output control.
 * Since most people are used to miners printing all the time, that's what we do by default too. This is suboptimal
 * really, since you cannot see errors under pages and pages of text and performance stats. Given that we have internal
 * performance monitors, there is very little reason to spew out pages of text instead of concise reports.
 * Press 'h' (hashrate), 'r' (results) or 'c' (connection) to print reports.
 * verbose_level - 0 - Don't print anything. 
 *                 1 - Print intro, connection event, disconnect event
 *                 2 - All of level 1, and new job (block) event if the difficulty is different from the last job
 *                 3 - All of level 1, and new job (block) event in all cases, result submission event.
 *                 4 - All of level 3, and automatic hashrate report printing 
"verbose_level" : 3,

 * Automatic hashrate report
 * h_print_time - How often, in seconds, should we print a hashrate report if verbose_level is set to 4.
 *                This option has no effect if verbose_level is not 4.
"h_print_time" : 60,

 * Built-in web server
 * I like checking my hashrate on my phone. Don't you?
 * Keep in mind that you will need to set up port forwarding on your router if you want to access it from
 * outside of your home network. Ports lower than 1024 on Linux systems will require root.
 * httpd_port - Port we should listen on. Default, 0, will switch off the server.
"httpd_port" : 0,

 * prefer_ipv4 - IPv6 preference. If the host is available on both IPv4 and IPv6 net, which one should be choose?
 *               This setting will only be needed in 2020's. No need to worry about it now.
