How to Deploy a Mochimo VPS Relay Node
Summary
The below steps will allow you to set up a VPS node that self-reboots weekly, installs the Mochimo server in a ramdisk (for high performance) creates a local mochimo service, and automatically restarts the Mochimo server as a non solving node upon reboot.
Audience
People who want to support the network by operating a node to relay transactions / blocks.
Minimum System Requirements
Ubuntu 16.04 LTS 1 vCPU 2 GB RAM 10 GB Hard Disk
Deployment Steps
1. Create ramdisk directory.
mkdir /mnt/ramdisk
2. Setup crontab to reboot daily. Below script selects nano with "1" and sets the system to reboot weekly at 6 am.
apt-get install nano cd /etc crontab -e 1
File Contents:
0 6 * * 1 /sbin/shutdown -r
3. Install build tools, and build Mochimo
apt-get install git apt-get install build-essential cd /root git clone https://github.com/mochimodev/mochimo cd mochimo/src ./makeunx bin -DCPU ./makeunx install
4. Tar the binary directory, and copy to /root
cd .. tar -czvf bin.tgz bin cp bin.tgz /root/bin.tgz cd .. rm -rf mochimo
5. Set the fstab to load the ramdisk on reboot
nano /etc/fstab
File Contents (append to bottom of file):
tmpfs /mnt/ramdisk tmpfs nodev,nosuid,nodiratime,size=1024M
6. Create the systemd system service to start Mochimo on boot.
cd /etc/systemd/system nano mochimo.service
File Contents:
[Unit] Description=Mochimo Server [Service] ExecStart=/root/start-mochimo.sh [Install] WantedBy=default.target
7. Make the service privs 644:
chmod 644 mochimo.service
8. Create the startup script off of /root
nano /root/start-mochimo.sh #! /bin/bash cp /root/bin.tgz /mnt/ramdisk cd /mnt/ramdisk tar -xzvf bin.tgz cd bin cp maddr.mat maddr.dat ./gomochi d -n -D
9. Make the startup script executable:
chmod +x /root/start-mochimo.sh
10. Start the service, and reboot to confirm:
sudo systemctl enable mochimo.service sudo systemctl start mochimo.service sudo reboot
