Hi
Would it be possible to do a tutorial on how to setup multiple masternodes on 1 VPS?

g_hash1

adam1970 Agreed, this would be a good tutorial! I set up my second tonight, and there were a few points where I wondered whether I needed to do things differently for multiple master nodes on the same server. For example, Why is sentinel required a second time? Do I just add to the same crontab but point to the new sentinel path? How to add the new port to the ufw firewall settings? Etc.

CliffonCrypto

Will do! Basically comes down to installing different nodes from the beginning. As long as each port differs it fine.

Can you set up (2) masternodes of the same coin on 1 VPS? For Example Monoeci and once it meets it's ROI spin up a second Monoeci masternode on the same VPS host or would you need a second VPS host at that time to have a different IP address?

TechniCrypt just found a link where you can set multiple masternodes of same coin, in that case it seems u have to buy an extra IP, but it cuts the cost of buying a whole new VPS conxn

Hey @TechniCrypt You can run multiple masternodes on a single VPS BUT they need to be different coins. Due to the IP and port number, you can only have 1 x Monoeci on a single VPS. You could however, have a different masternode running on that VPS ie ARCtic coin.

TechniCrypt

soc That is what I assumed but wanted to get verification from people who are currently running masternodes.

@CliffonCrypto In relation to multiple masternodes on a single VPS, how does it work with the swap file. You mention in your videos about optimising small VPS memory swap file. If we use the $5 VULTR VPS, and want to run 2 Masternodes of different coins, do we complete the SWAP file for root OR each masternode user?

TechniCrypt

soc /swap is usually system level not user based. Think of it like the PageFile on a Windows system.

CliffonCrypto

soc Just set 1 swap file.

What ends up being the limiting factor for multiple MNs on one VPS? Is it the memory needed to support the daemons? The potential future network traffic as coin popularity picks up? Or even the increase in CPU utilization?

@CliffonCrypto You mentioned in one of your early MN videos that you were experimenting with 10 MNs on one server, but I'm guessing that wasn't a $5 VPS ...

I've installed 4 MNs on one VPS and thinking about the fifth and sixth. Looks like I can easily start a new instance on Vultr and billing will adjust accordingly. Just wanted to think through these questions with this group.

Also, is it a better option to add a new instance? Or to increase the specifications of the existing instance to support more traffic (i.e. more memory, another virtualized CPU, etc.)?

CliffonCrypto

g_hash1 yea mostly Memory.

Its the risk you take. If the server is down, they all go down. Maybe spread the risk into another instance. But how often does it happen.

It more for security that i mix it up. In case it breached. Also ensure you encrypt and backup the wallets to cold storage.

ya, the 5$ vps wont cut it for 10. You ok there with 4.

CliffonCrypto Thanks Cliff! Roger on the security and backups!

CliffonCrypto You mean the wallet file on the VPS or the local wallet file (my local wallet is already encrypt)

CliffonCrypto

biggles71 on the VPS if you using the hot wallet.

CliffonCrypto Thanks cliff i'm using the windows wallet

I'm guessing you could technically add 2 of the same nodes on 1 vps provided you add a second IP address? but @CliffonCrypto, as you say, split the nodes for security reasons.

biggles71

@Spanner#Correct if you have muliple IPs and enough memory you can add the same node on one vps

Spanner

biggles71 Would it use the same .masternode daemon? How would you get a second transaction id for the second staking deposit?
Would "...-cli masternode output" display 2 transactions if you're trying to use the same .masternode daemon?

*just curious

biggles71

@Spanner I have never done this for MN but
technically you could run multiple instances of daemon on same server if you have enough specs and you configured different IP address to different network adapters. but administration can be more difficult. Also maybe getting the extra static IP and enough memory can be more expensive than creating a extra VPS.

Hi, all. I am new to running masternodes. So far I set up 2 xft masternodes on 2 different vps.
I now want to add a Smartcash masternode. Looking at the replys above I think I can add the SmartCash Masternode to one of the vps already in use (the $5 spec). That has 1024MB RAM.
In the Smartcash guide it says the VPS needs 1 GB RAM (half used for OS and half for the daemon)
So that would imply it needs its own VPS. Is smartcash an exception in the amount of RAM needed if with other masternodes you can put 4 on 1 VPS? Should I register it on a seperate VPS?
Kind Regards
