DASH Masternode Zeus (replacement for dashman)

[xkcd]

Dear All,

This is a dedicated thread for DASH Masternode Zeus (DMZ). It is an alternative to the aging DASHMAN. It installs a new masternode on a Ubuntu VPS according to my guide using a simple to use TUI. It is available from https://github.com/kxcd/Masternode-Zeus You can clone it and run it like so,

git clone https://github.com/kxcd/Masternode-Zeus
chmod +x Masternode-Zeus/masternode_zeus.sh
Masternode-Zeus/masternode_zeus.sh

Here are a couple of pictures of it in action.

I have decided to create a dedicated thread to the DMZ because it seems to be generally liked in the community, so I shall maintain it. Improvements I am looking to add to it is highlight (colour code) results that are an error in the above status screen. Try to make it support and manage multiplexed masternodes, add Evolution support and improve the Reclaim free space function to remove cruft the server builds up over time.

Something doesn't work for me. Ubuntu 20 LTS, Vultr.
I tried to reinstall dashd and sentinel , rebooted the server, no result. Help me please!

Actually, this is fine, it is syncing, refresh the screen after 1 hour, you should see blocks coming. It will take several hours to sync fully, the RAM is very low 2GB is pushing it, I think it will swap a lot and that will slow it down, so keep an eye on that.

 

[Comper]

Thanks for answers!
Yes, synchronization has already started.
2GB of memory for one node is not enough anymore?

Another question: Will DMZ work for several nodes on the same server?

Currently, it is not supported by the Zeus directly, but it is possible to do if you can bind more than 1 IPv4 address to the VPS. Refer to this guide on how to do it.

Multiplexing masternodes on single VPS

This guide will attempt to show you how you can run more than one Masternode (MN) on a single VPS a technique I call multiplexing. To save space due to data redundancy the masternodes will share a common blockchain. The guide assumes you have setup your masternode as per guide...

I'm sorry, but I can't do anything. Maybe 2 GB of memory is not enough?
After 10 hours of work, dashd began to synchronize very slowly, probably I would have to wait a week. I ran the command sudo reboot now.
After a reboot, port 9999 is closed for some reason and the script shows a dashd error and then dashd down.

Yeah, with just two 2GB, the RAM will fill and then code is placed into swap, the problem here at this that point, your machine can't even shutdown the dashd cleanly because it is basically stuck, so when you reboot, the systemd does a kill on dashd, now when the server boots back up, some databases will be inconsistent and dashd will fail to start at this point, this now requires your manual intervention.

Before we get to solutions are you able to increase RAM to the VPS to reach 4GB? I really think you should do that first.

Once you reconfigured, can use DMZ to check the debug log, there is an option to view it and use 'page down' to scroll to the end, it will tell you the issue, maybe some file is corrupt, eg something.dat, or maybe the wallet is asking you to do a -reindex, which ever it is there are solutions, if a file is corrupt, for example peers.dat, then as the mno user issue command like

sudo rm /home/dash/.dashcore/peers.dat

If it is some other dat file, just change the name above, systemd will automatically try to restart the dashd, so you can just wait 5 mins, OR try restarting it yourself.

sudo systemctl restart dashd

It might be several files with this issue, so keep checking the logs after restart to see what's next.

If the issue is you need to reindex, then use the DMZ to edit the dash.conf file. In there on a separate line put

reindex=1

and restart the dashd, or wait. monitor it and you should see it trying to index the chain again. Once it gets going, edit the dash.conf file and put a # infront of the reindex to comment it out, or delete that line, you can do this while the dashd is running, no worries!

For me personally, I have not been able to sync on 2GB RAM, I faced same issue as you, 4GB is the minimum these days.

 

[Comper]

Is it correct to restart the server with the reboot now command?
Maybe there is a script for the correct completion?

 

[Comper]

Thanks for the help.
Now I will try with 4 GB of memory.

 

[xkcd]

Yes! It is actually. That command is executed by systemd and it will cleanly shutdown all processes, including dashd, but if dashd is all swapped out and no longer responding, after a timeout, systemd will shoot it in the head and this causes problems on the next start up.

I updated to version 18 and it gives this result !! what's wrong?

Updated Sentinel ?

cd .dashcore/sentinel
git pull

Edit : your screenshot says you are on latest Sentinel version 1.7.1 but it also says Sentinel 'Failed'. Do you have a cron job active on Sentinel?

crontab -e

* * * * * cd ~/.dashcore/sentinel && ./venv/bin/python bin/sentinel.py 2>&1 >> sentinel-cron.log

Also a bit strange that your port 9999 is closed. You could check that with a third party ip / port checker.

 

[LWW]

when checking the port is open!! but Sentinel does not work ((everything worked before the update!

 

[LWW]

what does this warning mean?

Maybe clone the sentinel part again from the instructions ?

cd ~/.dashcore
git clone https://github.com/dashpay/sentinel.git
cd sentinel
virtualenv venv
venv/bin/pip install -r requirements.txt
venv/bin/python bin/sentinel.py

Source : https://docs.dash.org/en/stable/masternodes/setup.html

You can disregard the JSON RPC warning, something will be phased out or changed at some point in a future update. Not really relevant right now.

I updated sentinel with DASH Zeus

Okay, maybe best for you to discuss this further with xkcd.

The latest version of the Dash Masternode Zeus resolves this issue. I would recommend to update it. These steps should do it.

cd /tmp
git clone https://github.com/kxcd/Masternode-Zeus
chmod +x Masternode-Zeus/masternode_zeus.sh
cp Masternode-Zeus/masternode_zeus.sh ~/bin/

 

[LWW]

Did not work out (

OK. Updated code.

cd /tmp
git clone https://github.com/kxcd/Masternode-Zeus
chmod +x Masternode-Zeus/masternode_zeus.sh
mkdir -p ~/bin
cp Masternode-Zeus/masternode_zeus.sh ~/bin/

Once you have it installed, run it with

~/bin/masternode_zeus.sh

and use the option under the manage masternode menu to re-install the sentinel (this is how the issue is resolved).

Hello

I'm using Zeus and dash ver. 18.0.1. When I tried update it I got message error: "Download of has failed! Aborting..."
Full message in the attachment. What should I do to update my masternode?

Yep this is resolved in the current version, just clone the repo again and replace the one in ~/bin/

cd /tmp/
git clone https://github.com/kxcd/Masternode-Zeus
cp Masternode-Zeus/masternode_zeus.sh ~/bin/

 

[saturnx]

Works! Thank you .

so this bootstrap option 5. Bootstrap this server from another VPS running a fully synced DASH Masternode.

is that to be used before option 1. Install and configure a new DASH Masternode.

or after installation has been done ?

After installation is done, but I don't recommend the option, the sync is very fast these days, so you won't save time doing it this way IMO.
