Install and Configure xmrig for Monero XMR Crypto Mining

Ensure you have created and activated an account on https://minergate.com. You will need your minergate.com UserID before proceeding. 

 Install and Configure xmrig 

 Create a directory for xmrig under /opt: 

 mkdir /opt/xmrig 

 Download attached xmrig-linux.zip and extract to the /opt/xmrig directory you created above: 

 unzip xmrig-linux.zip -d /opt/xmrig 

 Edit /opt/xmrig/config.json file and under the following section: 

 

 "pools": [ { "algo": null, "coin": null, "url": "xmr.pool.minergate.com:45700", "user": "12345678", "pass": "x", "rig-id": null, "nicehash": false, "keepalive": false, "enabled": true, "tls": false, "tls-fingerprint": null, "daemon": false, "socks5": null, "self-select": null } ], 

 

 set the 123456 in the "user": "12345678"  section to your Minergate.com UserID. 

 Make /opt/xmrig/xmrig executable: 

 chmod +x /opt/xmrig/xmrig 

 Move the xmrig.service file that was included in the xmrig-linux.zip file to /etc/systemd/system: 

 mv /opt/xmrig/xmrig.service /etc/systemd/system/ 

 Configure CPU Quota 

 Adjust the CPU Quota that xmrig will use on your system by editing the  /etc/systemd/system/xmrig.service file: 

 vi /etc/systemd/system/xmrig.service 

 Insert the following line: 

 CPUQuota=50% 

 after the following line: 

 ExecStart=/opt/xmrig/xmrig --config=/opt/xmrig/config.json --log-file=/opt/xmrig/xmrig.log 

 So the whole service looks like below: 

 [Unit]

Description=XMRig Monero Miner

After=network.target

[Service]

User=xmrig

Group=xmrig

StandardOutput=journal

StandardError=journal

ExecStart=/opt/xmrig/xmrig --config=/opt/xmrig/config.json --log-file=/opt/xmrig/xmrig.log

CPUQuota=50%

Restart=always

[Install]

WantedBy=multi-user.target 

 Adjust the percentage from the default 50% to a level appropriate for your system. 

 Save the /etc/systemd/system/xmrig.service file. 

 Create User for xmrig 

 Create a user for xmrig: 

 sudo adduser xmrig 

 Set a password for the xmrig user and answer the resultant prompts 

 Give xmrig user root privileges: 

 usermod -G sudo xmrig 

 Configure Logging 

 Create /opt/xmrig/xmrig.log file: 

 touch /opt/xmrig/xmrig.log 

 Set /opt/xmrig/xmrig.log file permissions: 

 chmod 664 /opt/xmrig/xmrig.log 

 Set /opt/xmrig/xmrig.log file owner to the xmrig user created earlier: 

 chown xmrig:xmrig /opt/xmrig/xmrig.log 

 Enable and Start xmrig Service 

 Enable the xmrig service: 

 sudo systemctl enable --now xmrig 

 Start the xmrig service: 

 sudo systemctl restart xmrig 

 Ensure xmrig service has started: 

 systemctl status xmrig 

 If the service is started, the output should be similar to below:
