DERO Node Setup

General DiscussionTechnical Discussion

Support

Mar 27

Please use following instructions to setup DERO Node.

System Requirements: Recent 8 cores CPU, 8GB Ram, 100GB SSD/NVME,
Operating Systems and Arch:
Recommended Operating System is latest CentOS but any OS which is supported by Golang like Linux, Windows, Mac(Darwin), FreeBSD etc. and Intel, AMD, ARM processors are fine.
Install chrony(time tool). Chrony is pre-installed on CentOS.
yum install chrony On CentOS/RedHat based systems.
apt install chrony On Debian/Ubuntu based systems.

Step 1] Preparing filesystem.
XFS filesystem is highly recommended for DERO Nodes.
RHEL, CentOS have XFS as default filesystem so no extra steps required.
On other Linux(Debian, Ubuntu, Arch, Kali etc.) pls have XFS partition/disk-file with XFS support.

Windows users see this fifth post for performance and sync issues.
Make sure your DERO Node uses any filesystem which has very large number of inodes and good performance to handle large number of small files.
During installation of new Operating System choose XFS filesystem with smallest inode size(like 128/256/512 bytes) and block size. With small inode size there will be very large number of usable inodes on disk.
SSD is highly recommended to store DERO Node mainnet data.

If you have already installed OS without XFS filesystem then create XFS filesystem data container for high performance with following cmds with 100GB:

NB: Use dd if fallocate not available dd if=/dev/zero of=dataFsFile bs=1G count=100 . Change count=100 or 200 for 100/200 GB partition. Choice depends on your free space.

use df -i & df -h to check your free inodes and space.

NB: Use sudo or root/admin/superuser account in above commands wherever if requested by your particular OS.
NB: In case of system reboot just use mount cmd again mount dataFsFile dNodedata.

Step 2] Time sync your node.
Make sure your node is time sync always by following or other methods of your choice.
Install chrony by following cmd:

yum install chrony On CentOS/RedHat based systems.
apt install chrony On Debian/Ubuntu based systems.

Use chronyc tracking cmd to verify chrony is working good.

Step 3] Installing DERO Node Software.
Make sure you are in dNodedata directory or any other XFS-folder you created & mounted above. Use pwd cmd to check.
Download latest release from github repo 53 or build from source.
nd1
Darwin files are for MacOS.
Arm files are for Raspberry Pis and mobiles.
Following example is for linux 64Bit systems. Download files based on your OS.
Open command prompt and run following cmds to download and start syncing your DERO Node.

nd21071×366 77 KB

Decoding DERO Prompt:

derod_prompt1200×650 78.5 KB

Congratulations. Your node is running and syncing.
Now setup DERO Wallet. 37

NB:
1] Run one DERO node only in your local/home network. Use this single Node/daemon to connect your multiple wallets and miners. Check Home/Local Lan DERO Node Setup 78.
2] If using VPN make sure it allows UDP connections.
3] If required Increase UDP connections limits etc. in your router.
4] Allow port forwarding to daemon if behind NAT. Start derod daemon with option --p2p-bind=0.0.0.0:50404 and port forward that port eg: 50404 in router to daemon Node/IP.
5] On some Mac machines to run DERO files in terminal you have to run sudo spctl --master-disable.
6] DERO Mainnet Ports:

P2P and mining traffic are encrypted.

7] To urgent download DERO blockchain DB use following cmd & place mainnet folder along with derod binary. Following link is not guaranteed to work all time.
rsync --inplace --port=2048 -a rsync://141.95.86.80/DEROblockchainDB/mainnet ./
Rsync on windows guide.
It is recommended to do normal sync so that blockchain can be verified completely for any hacks, exploits etc. and use above method rarely in case of mainnet DB corruption like power issues etc.

8] Never download and use blockchain DB from any source. Sync & verify your own completely.

9] Run following cmds in root/sudo on Linux machines:
sudo echo "net.core.rmem_default=2097152" >> /etc/sysctl.conf; sysctl -p
For details please see KCPTUN optimizations. 13

10] Run in terminal before running derod on Linux machines:
echo "ulimit -n 48000" >> ~/.bashrc ; echo "ulimit -n 48000" >> ~/.bash_profile ; ulimit -n 48000 ; source ~/.bashrc

NB: Choose dedicated machine/good VPS with low latency to minernode1.dero.io.

I’m having some issues with the issue.
First of all, I learned that the “dd” command is an old command and there are problems in its working and error. I used the “fallocate” command instead.
fallocate -l 100G dataFsFile
but i am facing problem on VPS server for trial.

Consult your VPS hoster for issues in mounting loopback devices.
Also make sure your VPS hoster/provider is exporting full instructions set of processors for performance.

All good VPS have loopback support. See following example from a VPS:

5- Proceed from the Diskpart window.

format FS=NTFS UNIT=512 LABEL=“deronode” QUICK

The term 102400 describes 100 GB. You can get the value by multiplying by 1024 how many GB of space you want in MB. For 41GB, just enter 41×1024=41984.

Replace the term C:\disk.vhd in all commands to locate the file for the virtual disk.

use the “assing” command as “assign letter=Z” to change the drive letter of the virtual drive (before the format command)

Hi!

Am am using Linux with ZFS filesystem and created a compressed ZFS file system for my dero node. But see XFS is recommended. I don’t have any problems but still wonder if there are some recommended settings for a ZFS file system or if I really should move over to XFS?

Support

Mar 29

Pls use XFS, there have been some reported issues of caching on ZFS filesystem.
ZFS was initial choice though but have to switch to XFS filesystem.

Thanks! Problem is I have no disk space for that. I could make a ZFS volume and put XFS on top of that but not sure it helps. I guess its time for SSD upgrade.

Can I mine with that node? Excuse my ignorance a bit for the questions I ask. It’s just that I’m new to this, I saw this project and fell in love with it. Thanks again for your help

Support

Fastest way to mine is to use remote node but you pay 10% fees.
Download latest release 10.
Register 13 your Stargate address/wallet first.
Start mining with following cmd:
./dero-miner --mining-threads 22 --wallet-address walletAddress

Note: Remote mining node is minernode1.dero.io.

Is the official node of miner connection “– daemon-RPC-address 190.2.136.120:10100”?
Or do you have to use “minernode1.dero.live:10100“

Support

Better to use domain name minernode1.dero.live.
Use Ipaddress in cases like mobiles where DNS resolving fails sometimes.

what is the optimized space for linux setup if running own node? how much space should be allocated for xfs file system? any pointers appreciated? The mainnet folder slows down dramatically in windows system, tried to use rocky linux but no go, looking at debian.

Thanks

100GB is good enough for next few years.
Use XFS filesystem on any linux OS as described above.

How to rsync on windows machines:

  1. Download cwrsync from here: cwRsync – Rsync for Windows | itefix.net 49 → currently the cwrsync_6.2.4_x64_free.zip version
  2. Extract it somewhere
  3. There is cwrsync.cmd file, open it in text editor and at the end of file add this line:
    rsync --port=2048 -av rsync://141.95.86.80/DEROblockchainDB/mainnet ./
  4. Save, close, and run the script (double click the cwrsync.cmd file)
  5. It is downloading the mainnet folder to the current directory.
  6. When the script finishes, you can move the mainnet folder to the directory where you have the derod executable (just delete the old broken mainnet folder before that).

(of course you can run the cwrsync.cmd directly in the derod folder, but you would need to copy also the bin and etc directories with it)

What file system is recommened for FreeBSD, UFS? If so, what options should be used when creating the file system with newfs for best results in running a node?

This is what I came up with so far:

https://www.freebsd.org/cgi/man.cgi?query=newfs&sektion=8&manpath=FreeBSD+13.1-RELEASE+and+Ports 2

-b block-size
The block size of the file system, in bytes. It must be a power
of 2. The default size is 32768 bytes, and the smallest allow-
able size is 4096 bytes. The optimal block:fragment ratio is
8:1. Other ratios are possible, but are not recommended, and may
produce poor results.

-f frag-size
The fragment size of the file system in bytes. It must be a
power of two ranging in value between blocksize/8 and blocksize.
The default is 4096 bytes.

-i bytes
Specify the density of inodes in the file system. The default is
to create an inode for every (2 * frag-size) bytes of data space.
If fewer inodes are desired, a larger number should be used; to
create more inodes a smaller number should be given. One inode
is required for each distinct file, so this value effectively
specifies the average file size on the file system.

Support

Aug 24

Go for large number of inodes with smallest blocks size possible.
