Topic: Electrum server on Windows (or VirtualBox, or, even better, WSL) (Read 372 times)
Good tip, thank you!

You have brought Electrumx to run? Can you help me with that? I also installed the RPC Explorer, but it needs Electrumx to display addresses.
I fails to successfully start ElectrumX.
I fails to successfully start ElectrumX.
I've installed Electrs, not ElectrumX. Electrs install went very easy on Debian under WSL.
BTC RPC explorer seems to be happy with Electrs.
I plan to write down the steps - probably in the week-end.

Based on my past experience, BTC RPC Explorer is easy to install. While mempool.space have lots of dependency (such as Electrum Server & MariaDB), this one only require you to install Bitcoin Core and Node.js.
As a minus, the look & feel is not that great. On the other hand, it doesn't have yet another database, which is very nice - having 3 databases for the same thing (just because electrum server and blockchain explorer are made by different people) is counterproductive.
I may give it a try, let's see how hard it is to install/configure. Thank you.
Update: in under 1h I've got this also running. Impressive! Thank you for the hint!

2. I could use some suggestions for the block explorer to install. Is it mempool.space or is there any better/easier one?

Many thanks HCP, this was the correct solution.
It wasn't straightforward at all, as a matter of fact I almost gave up at some point and I even unistalled Ubuntu after a couple of tries. But I've tried again, with Debian under WSL. I may have been making useless steps too, but I've finally got to the sweet:
Some notes:
When all is done I may even make another post with the steps, since I expect to not be the only Windows user here
Questions (need help) :
1. Is there any way to make electrs not fail (and instead retry later) if bitcoind is not available yet?
2. I could use some suggestions for the block explorer to install. Is it mempool.space or is there any better/easier one?

Code:
[2021-10-16T13:31:39.392Z INFO electrs::server] serving Electrum RPC on 127.0.0.1:50001
Some notes:
- For now already the Debian folder takes 4 GB on my C: drive although Bitcoin runs under Windows and electrs actual data dir (30 GB) is set to somewhere else.
- The errors under Ubuntu were from not finding librocksdb-dev 6.11.4-3 to not "knowing" how to create files and folders on a Windows NTFS drive/folder. Not nice.
- For now it works well, but it uses bitcoind .cookie instead of user/pass, and I want to also make it start automatically, maybe also not fail if bitcoind didn't finish syncing, and obviously also install a block explorer.

So.. what Linux flavor you suggest I should install? Ubuntu?
Ubuntu is as good as any other distro... plus it's basically available on the Windows App Store. 
WSL is actually insanely easy to use... and it does nifty things like offer you /mnt/
You might want to have a quick read of some of the basic stuff here: https://docs.microsoft.com/en-us/windows/wsl/

Later on I managed to make Electrum Personal Server work on Windows, but that's still not enough, since as step 2 I intend to also get a block explorer.
I intend to try now @HCP direction with WSL; from what he said here, his setup looks very promising.

Alright, however you should know you can always compile ElectrumX and whatever block explorer you need using MSYS2 (https://msys2.org) windows terminal - which includes the MinGW build tools that let you compile Linux programs on Windows.
But forget about this if any of your tools are written in NodeJS because it starts to become very messy to compile (they don't provide a NodeJS interpreter in their package manager).

@NeuroticFish, why are you running bitcoind and ElectrumX inside a virtual machine (if I'm understanding the discussion correctly), when disk ops are notoriously slow on an emulated disk-as-file and disk controller?
Yes I know your datadir is on an external drive, but Virtualbox emulating the disk controller means that bitcoind will take a serious performance hit.
[also for some reason I have discovered bugs where VM network traffic is dropped, so beware of that as well].

I was planning to not use emulated disk, at least (not) for bitcoin datadir. I was planning to use the shared disk functionality (or connect directly to the USB) and use the external USB disk I already have with a pretty much up to date datadir.
The VBox direction was chosen because I have to have Windows as main OS and I failed to install - at least at start - any reasonable Electrum server onto Windows. And on VBox I managed to have a Linux working with my USB disk. I've noticed that's not the best direction (and thanks for the heads up about the traffic!), but it was the best I could think of. After reading about Docker I am afraid to use it on this machine (I don't want to have to reinstall windows if I do something wrong).

Any particular reason you didn't want to use "Windows Subsystem for Linux" (WSL)? 
Mostly because I'm a stupid windows-head and although I heard about it, I've never used WSL and never actually needed it, since VBox (and before that VMWare) always did all I needed (usually clean Windows for tests).
And it didn't occur to me at all that this could be the way. Thank you!
I was able to get both "electrs" running under WSL. electrs was reading Windows-based Bitcoin Core block data and I was able to connect to electrs from a Windows-based Electrum client. In my opinion it was certainly a lot easier than messing about with VirtualBox.
Since you have that, I'll try to abuse your kindness and try to replicate your setup
, basically if I run into odd newbish issues at least I have the chance somebody can answer electrs actually sounds very good to me, at least it solves the requirements for a block explorer which I also wanted (as a step 2).

I vaguely recall I also managed to get ElectrumX working, but preferred electrs.
Was using VirtualBox, simply a way to keep everything segregated for "security" reasons?

And for extra fun if you still have VirtualBox installed and running and since Docker uses Hyper-V....there are more steps that you have to go though at times.
You can google for more but here are a few links:
https://us.informatiweb.net/tutorials/it/virtualization/virtualbox-use-virtualbox-and-hyper-v-at-the-same-time.html
https://derekgusoff.wordpress.com/2012/09/05/run-hyper-v-and-virtualbox-on-the-same-machine/
Or just remove virtual box if you don't need it.

I've done my reading, it was indeed interesting and useful, thank you for that. It cleared up some of old things
I was using VirtualBox - very rarely, but still - for many years. Since before Win10 that's for sure. And I remember I had errors related to Hyper-V in VirtualBox, including that black screen.
I don't know if it's because of those problems, I really don't remember, but my host Win10 doesn't have Hyper-V installed. For a while I was even installing only x86 systems (Windows?) on VBox because the x64 failed. And I blame Hyper-V
So.. I don't know why I would keep enabled Hyper-V; I've been using my computer very well with it off. Maybe the fact my Intel CPU supports VT-x is of help; maybe this is the trick that kept me away of problems lately.

I have a new problem now.
For now I am testing with my current HW having quite a number of addresses and transactions.
But most of my addresses are displayed with red background, my transactions are shown as "This transaction is only available on your local machine", and the final sum of coins shown is 0.

I've changed EPS config from
Code:
initial_import_count = 1000
gap_limit = 25
togap_limit = 25
Code:
initial_import_count = 10000
gap_limit = 125
gap_limit = 125
It may very well be overkill (the rescan was sooo slooow....), but my wallet looks good now.
Of course, next step is a server that works with more than one wallet. And I've read that mempool may need electrs...
Hyper-V
Thanks, I will have a read, although my VBox stays 95% of the time stopped (and I intend to keep it so). But I expect to be interesting.

If you're looking for simple setup, you should use ElectrumX which packaged on Docker (https://github.com/lukechilds/docker-electrumx). You just need to run one command to run ElectrumX server. But AFAIK installing Docker on Windows is a bit annoying.
Thank you. I will look into this too; hopefully tomorrow.

V i c t o r y ! (sort of)
Later note: I managed to install Electrs too. I will provide steps at a later point. Electrs allows as many wallets as you want and block explorer too. I find that a better approach.
With some knowledge earned from last night's tests with Sparrow wallet and from reading a tutorial for RasPi which I found better than the one everybody reads it, I managed to make Electrum Personal Server work on my Windows.
Highlights
bitcoin.conf must have:
I have some more (probably unnecessary) things from the previous tests with various servers, but if there are problems, these can be added:
In EPS config.ini I added only 2 lines, nothing else had to be changed (during my tests I had other settings there and just made the things worse).
One thing (or two) that was always missing in my tests and may be just the part I've missed in the official tutorial (thank you Sparrow wallet) :
From here, according to the tutorial:
Now Electrum connects:

but it should just be a matter of getting Python3 installed, then using PIP to install the remaining dependencies.
First of all, thanks for the help.
Now... I've just tried this ElectrumX for Windows path. Installed Python (for the 1st time), used pip for aiohttp, then failed at pylru:

So the directions I have:
1. [preferred] Make an Electrum server and a block explorer work on Windows
2. Anything I can install on Virtual Box as long as Bitcoin DataDir remains on the USB attached HDD. This is a special problem, since I am badly inexperienced with Linux.
2.1. I do have a Debian configured on a Virtual Box, with DataDir just fine, but I don't know how to make bitcoind start automatically with the system (and with that datadir); I didn't go with other steps yet there.

In the ElectumX documentation, on the "HOWTO" page there's a claim that ElectrumX should be able to run on Windows.
ElectrumX should run on any flavour of unix. I have run it successfully on MacOS and DragonFlyBSD. It won’t run out-of-the-box on Windows, but the changes required to make it do so should be small - pull requests are welcome.
I've never tried to run it on Windows, but it should just be a matter of getting Python3 installed, then using PIP to install the remaining dependencies. You would then need to set up the proper service command to create a service that starts automatically when the machine boots up or the user logs in. I'll try it one of these days, and report back.
As for bitcoind running in the background as a service in Linux, the instructions to use systemd are available in the bitcoind.service sample file found in the master repository.
Note: If you're not running around as root, you'll need to use sudo before each of the following commands.
This code will create the systemd configuration file:
Code:
systemctl edit bitcoind.service
Copy the commands you want into the file and then save it.
Enabling the service will cause it to start at boot, to do so use this command:
Code:
systemctl enable bitcoind.service
To start the service manually use this command:
Code:
systemctl start bitcoind.service

I had asked about it before on these forums, but even the regular Electrum server there isn't much other than the docs on it's website. But ... source code is out there if you know how to read and audit it, can also compile it yourself. The whole idea of running anything in it's own Virtual Machine should probably be the default for most users. At least it's a full node server that doesn't do anything else it's not supposed to do (or you can monitor it for that.)
September 27, 2021, 10:14:56 AM
I'm going to try fulcrum one day. It says on the github that "it should just work." and I discovered it because I keep looking at my electrum wallet console all the time and watch what server it connects to.
The thing is that form my search, here on Bitcointalk English areas, it was only you mentioning it. No offense, but I'd wait for a bit more, since "it should just work" doesn't imply that it would also do exactly what we'd expect. Maybe I'm paranoid, still, it would mean I'm running new unknown software with not much of trusted reviews.
I've seen a bit of info on Reddit, but mostly in BCash areas, which I skipped super fast.
