Install XMRig CPU Miner on Ubuntu 20.04 with CLI

If you were able to complete the above instructions successfully, you’re now ready to mine XMR on your Ubuntu 20.04 or Ubuntu 18.04 machine. There are two methods you can use the miner. The first method is by,

Using command line…

This is not the preferred way to use the miner. We’ll be passing the arguments directly from the command line with a single command. Following is the command to use,

/root/xmrig/build/./xmrig -a cryptonight -o stratum+tcp://pool.supportxmr.com:5555 -u MoneroAddress -p MinerIdentifier:Email -t 1

This will mine Monero on supportxmr.com with 1 CPU. Change your MoneroAddress, MinerIdentifier, Email and the number of treads with the -t vaule towards the end.

The second and the preferred method is by,

Using JSON config file…

In this method, we’ll store miner config in a json file. Let’s create it in the build directory,

nano /root/xmrig/build/config.json

Now use the configuration wizard to generate your XMRig miner configuration. Paste the output from wizard to the config.json file. It should look something like this,

{
    "autosave": true,
    "cpu": true,
    "opencl": false,
    "cuda": false,
    "pools": [
        {
            "url": "pool.supportxmr.com:443",
            "user": "4A5Zv5vpNcG4Tk7pF6wRHha6jZEgoF9UgFv49qijdHxeLSLYCWyCbHZA6sqBiWRSwcBcnBrJuEWxjYgtwJAQnzcT3BDvq8m",
            "pass": "test",
            "keepalive": true,
            "tls": true
        }
    ]
}

Now close the file by hitting Ctrl+X. Following command will launch the miner and start mining Monero on Ubuntu 20.04.

/root/xmrig/build/./xmrig

That’s it. You can further optimize your mining with xmr-node-proxy if you have more than 10 miners. Happy mining!!
