Was there such configuration file for electrumx? In the docs you linked it says that there should be different files for each environment variable. For example, it says that you'll have to create the COIN, DB_DIRECTORY and DAEMON_URL necessarily and some others optionally.

Different setup (systemd, docker and svscan) use different way to configure the environment variable.

Anyway, yes, if I understood your question correctly, docker does allow you to do that. You just need to add parameters on your script. Three posts above, @ETFbitcoin included the DONATION_ADDRESS param. You can do the same for the banner:

Code:

-e BANNER_FILE=LOCATION_OF_YOUR_BANNER_FILE

Note that the location starts from the electrumx data directory which means that if you enter BANNER_FILE=banner.txt, it'll search for /home/user/electrumx:/data/banner.txt

Yeah, that was my question. I guess it does simplify the installation by using the docker image. I'm just so used to systemd, and I find it simple to enable a process to run at machine startup.

Using docker is simpler (even if you barely know how to use docker), but you also need to trust lukechilds who made the docker image (unless you inspect the docker image).

But i also prefer systemd for elecrrumx, since it's easier to manage the service (enable/start/stop) and environment variable.

Please share some more informations, I also wanted to start with electrum, but failed to install and run. Lets help us each other if you are also at the beginning.

1. Be more specific, what did you try and what's the problem?
2. OP already mention what he did to run electrum server

Quote from: BlackHatCoiner on April 30, 2021, 03:42:37 AM

I then watched a video on YouTube which was much more simpler than with electrumx's tutorial. Thus, I discovered electrum personal server which seems a great implementation under some serious development.

Honestly if the VPS use linux, you can use easy installer/docker (which i mentioned above), which is very easy to use.

I saw the docker, but I haven't ever used docker in the past for setups. Would you mind guiding me a hand? There's no steps, just a “docker run /” script.

I rarely use Docker, but here's short guide (i've tested it on my device, but don't know whether it runs on WSL)

1. Install docker

Code:

sudo apt install docker.io

2. Test whether docker run correctly

Code:

sudo docker run hello-world

If you see message "Hello from Docker!", then Docker run correctly.

3. Create directory which used to store electrumx data

Code:

cd /home/user
mkdir electrumx

4. Run this command

Code:

sudo docker run \
-v /home/user/electrumx:/data \
--net="host" \
-e DAEMON_URL=username:password@localhost \
-e COIN=Bitcoin \
-e NET=testnet \
-p 50002:50002 \
lukechilds/electrumx

Here's short explanation

1. --net="host", this command is used to ensure the container can access host port.
2. -e used to configure environment for electrumx.
3. -p HOST_PORT:CONTAINER_PORT is used to expose and link port between host and container.
4. -v HOST_DIRECTORY:CONTAINER_DIRECTORY is used to link host directory on the container.
5. lukechilds/electrumx means container we're going to use

P.S. If you want ElectrumX container to automatically start after boot, add --restart=always when you run docker.

Yes, you'll find it in .../contrib/systemd/

No, all you need is one .conf file, all the environment variables can go there. For example:

Code:

COIN = Bitcoin
DAEMON_URL = myrpcusername:myrpcpassword@localhost:port
SERVICES = tcp://my.domain.name:50001,ssl://my.domain.name:50002,rpc://
REPORT_SERVICES = tcp://myaddress.onion:50001,ssl://myaddress.onion:50002
SSL_CERTFILE = /path/to/sslcertfile.crt
SSL_KEYFILE = /path/to/sslkeyfile.key
DONATION_ADDRESS = 157v67atJjnx7Fdi2wmcBBpChugHNmDWup
BANNER_FILE = /path/to/file.banner

3. Setup with systemd, https://electrumx-spesmilo.readthedocs.io/en/latest/HOWTO.html#using-systemd

I've read about the installer, but this is the first I've heard about people using docker to run electrumx. I'm not familiar with docker, so seems like a rabbit hole of it's own. I just use systemd to run bitcoind and electrumx. Old dog, new tricks, and all that.

Does the docker method allow one to use all the same environment variables that one might enable in electumx.conf?

Sorry, but I hadn't noticed that the DAEMON_URL was expecting two input fields (username and password). Once I entered it correctly, it started the server.

I'd like to mention that you can change value of other parameter (such as where do you store electrumx file) or add additional environment parameter.

Quote from: BlackHatCoiner on May 03, 2021, 02:06:27 AM

Before exposing it to the internet, I'd like to firstly try it on LAN. It seems that with the way you've described me, it works only on localhost. Do I simply change the DAEMON_URL from localhost to 192.168.x.x?
Can you explain a little further the last one you mentioned (container)? I don't have the electrumx files on my computer. Where does it execute the commands and from what files? Github?
How do I change the banner/donation address? I've created a file called "DONATION_ADDRESS" containing a legacy address as being said on electrumx's documentation, but it doesn't seem to read it.

1. AFAIK yes.
2. You should search what is docker and how docker works. Here's an article i found https://devopscube.com/what-is-docker/.
3. You need to add another parameter when run electrumx

Code:

-e DONATION_ADDRESS=YOUR_BITCOIN_ADDRESS

P.S. Those are good question, but unfortunately i'm still newbie when using Docker.

It works! Cheesy

Sorry, but I hadn't noticed that the DAEMON_URL was expecting two input fields (username and password). Once I entered it correctly, it started the server. That actually happened yesterday, couple hours after my last post, but I went offline, so I couldn't inform about it.

Alright, so I have some questions to make regarding electrumx:

If you see message "Hello from Docker!", then Docker run correctly.

On the WSL I don't get it. I returns me an error instead. But don't worry, I'll setup it on my Ubuntu machine. On my Ubuntu 18.04 the hello-world works properly, but not the script you've given:

I think it's software, but I ain't completely sure. It's really cheap so I doubt if it'd be a hardware one.

I have been experimenting with electrum as a wallet since I learnt about bitcoin, a year ago, and I can admit that it's the simplest and most useful one. I'd like to run my own electrum server, but not for privacy reasons, just for exercise. I also have bought a Windows VPS that isn't being used at the moment, so why not providing it to the electrum community?

I picked electrumx, because it's the most popular implementation. It seems that I can't install it on windows, only on unix. The thing is that I don't have an Ubuntu installed right now. Could this work with Windows 10 on an Ubuntu LTS?

Other questions too:

Is the same procedure if I want to run a testnet server? I don't have the storage for downloading the entire blockchain.
How does it return the balance of address(es) instantly? On Bitcoin Core it has to rescan the blockchain (which will take a lot of time).
Will I be shown on others' network servers? If no, how can I be shown?

Hello,

Please share some more informations, I also wanted to start with electrum, but failed to install and run. Lets help us each other if you are also at the beginning.
And the VPS is hardware or software or rented? Because I heard that is possible, personally I didnt saw such a witchcraft

I do. I just wanted to firstly setup a personal server. Running a server publicly is secondary.

3. Setup with systemd, https://electrumx-spesmilo.readthedocs.io/en/latest/HOWTO.html#using-systemd

The problem with electrumx is that I still haven't understood how it works. For example, on electrum-personal-server, you're starting the server with electrum-personal-server config.ini. With what file do you start electrumx? service/electrumx?

The tutorial doesn't tell you much. It just says "run that command, then another command etc.". Where's the explanation? How am I supposed to know what does that do and from what directory should I run it?:

Code:

systemctl start electrumx

This is what it returns me when I execute the above command:

Code:

angelo@angelopc:~/Desktop/electrumx$ systemctl start electrumx
Warning: The unit file, source configuration file or drop-ins of electrumx.service changed on disk. Run 'systemctl daemon-reload' to reload units.
Job for electrumx.service failed because of unavailable resources or another system error.
See "systemctl status electrumx.service" and "journalctl -xe" for details.

And then with systemctl status electrumx.service (as it's been said in the error):

Code:

angelo@angelopc:~/Desktop$ systemctl status electrumx.service
● electrumx.service - Electrumx
Loaded: loaded (/etc/systemd/system/electrumx.service; disabled; vendor prese

Aπρ 30 15:22:14 angelopc systemd[1]: Failed to start Electrumx.

(Aπρ is Apr on my lang)

As I said, I have a VPS left over and I'd like to "donate" its operation to the electrum community instead of having it shut down. I also like practicing in this field. I'd have probably given up with this setup, but it seems that I'm a stubborn...

So, I just switched to EPS. I didn't fix electrumx. I may formulated it wrongly, but "fixed" goes to my main purpose, which is running electrum without trusting anyone. I achieved it, thank you for your help.

As long as you accomplish your goal Roll Eyes

But if you want to use electrumx to make Electrum server which is publicly accessible, you can consider,
1. Easy installer, https://github.com/bauerj/electrumx-installer. Although i don't know how well it works.

I have successfully had electrs running under WSL+Ubuntu (reading a Windows based Bitcoin data directory and connecting to it from Windows based Electrum)... it works a treat and has a relatively small footprint. It "syncs" relatively quickly if it's been offline for a few days, although the initial build+initial sync process can take a while.

In the end, i decided to try setup electrumx from scratch and i think successfully setup it based on the log file.

Code:

This is how i do it. Hopefully i don't forget any step or copy wrong command

1. Install daemontools

Code:

sudo apt install daemontools

2. Move to proper path

Code:

cd ~/Desktop
git clone https://github.com/kyuupichan/electrumx.git
cd electrumx

3. Configure Python virtual environment (optional)

Code:

python3.8 -m venv .venv
source .venv/bin/activate
mkdir ./DB

4. Install electrumx (i think it's optional)

Code:

pip install .

5. Create directory service

Code:

mkdir ./service

6. Copy the daemontools script

Code:

mkdir -p ./scripts/electrumx
cp -R ./contrib/daemontools ./scripts/electrumx

7. Configure ENV. Make sure to read this guide https://electrumx.readthedocs.io/en/latest/environment.html#environment

Code:

cd ./scripts/electrumx/daemontools/env
nano DB_DIRECTORY

Here's value i used

Code:

FILENAME=VALUE

COIN=BITCOIN
DAEMON_URL=USERNAME:PASSWORD@LOCALHOST
DB_DIRECTORY=/home/user/Desktop/electrum/DB
NET=TESTNET
ELECTRUMX=/home/user/Desktop/electrumx/.venv/bin/electrumx_server
USERNAME=user

8. Configure log path. Change /path/to/log/dir to /home/user/Desktop/electrumx/scripts/electrumx/daemontools/log

Code:

cd /home/user/Desktop/electrumx/scripts/electrumx/daemontools
nano run

9. Start svscan

Code:

cd /home/user/Desktop/electrumx
svscan ./service

If you can't have multiple terminal run this instead

Code:

cd /home/user/Desktop/electrumx
svscan ./service & disown

10. Add the service

Code:

cd /home/user/Desktop/electrumx/service
ln -s /home/user/Desktop/electrumx/scripts/electrumx/daemontools electrumx

11. To see output from Electrum

Code:

cd /home/user/Desktop/electrumx/scripts/electrumx/daemontools/log
tail current

P.S. It's very complicated compared with setup for systemd system or using docker (https://github.com/lukechilds/docker-electrumx).

Sorry, i made a mistake, it's been some time since i tried electrumx and not familiar with daemontools (usually i use systemd).

If you're using an implementation of the server that has a simpler tutorial, feel free to give me a link please! The problem with systemd is that I get this:

Code:

angelo@DESKTOP-5QOEJVC:~/electrumx$ systemctl start electrumx
System has not been booted with systemd as init system (PID 1). Can't operate.

Quote from: ?? on ??

sudo affect how you run Electrum with daemontools, not where environment file is locate

I meant that I'm running the commands from “angelo”, which is the main user probably.

Quote from: ?? on ??

How do run electrumx? Simply by typing electrumx_server? If yes, i think that's the problem since you're following guide to configure/run electrum with daemontools.

I don't understand. Should there be a command for daemontools that will start the electrumx server? The only thing that is mentioned about those tools is this: https://github.com/spesmilo/electrumx/blob/master/docs/HOWTO.rst#using-daemontools

This is how I've modified DB_DIRECTORY on scripts\electrumx\daemontools\env:

Code:

E:\p2p\BTC\AppData\testnet

That's not likely to work... WSL knows nothing of "Windows" paths... so things like "E:\" etc don't mean anything.

However, WSL should be mounting all the Windows drive letters under /mnt (and in lowercase!)... so you should be able to use something like:

Code:

/mnt/e/p2p/BTC/AppData/testnet

Assuming you're using daemontools and install as regular user (not as root), then yes.

What would be the difference? I'm not sure if I have installed it as a regular user. I have used sudo for most of the commands, because it kept returning me that I don't have permission. The electrumx directory is located on the main user (angelo) and not on electrumx.

But few configuration file such as "DB_DIRECTORY" should be available by default.

The bitcoin's testnet block chain is downloaded on my external drive. Not inside any of the ubuntu's directories. Could this be the issue?

Yes. You need to configure the environment variable which mentioned on the electrumx environment docs.

Thanks. Are these environment variables located at home\\scripts\electrumx\daemontools\env ?

Could it be a configuration issue?

It builds the index from the bitcoind blockchain, hence why you need it.

Does it need the entire chain once it builds the index? Can't you get rid of it later? Just wondering why you can't build the index by running pruned node.

The short answer is "Yes"... the long answer is: I don't know if you can remove it later, there are personal servers that run on Pruned nodes, with the caveat that if you attempt to import addresses/keys or a new wallet, it may not show the full balance given that blocks are "missing". However, ElectrumX requires the full blockchain, AFAIK.

Why don't you try and prune the blockchain after ElectrumX has synced and then report your findings here?

I have opened the Bitcoin Core application (using ./bitcoind --testnet) but once I run the above command I get:

Code:

angelo@angelo:~/bitcoin/bin$ ./bitcoin-cli -testnet -rpcuser=root -rpcpassword= getinfo
error: Authorization failed: Incorrect rpcuser or rpcpassword

I have entered the same username and password on bitcoin.conf. What am I doing wrong?

Don't use rpcuser and rpcpassword... they're being deprecated... either use the rpcauth or the .cookie file...

The .cookie method is easiest... if you used the "default" datadir then you should just be able to not specify anything and it will just work... if you've specified a custom datadir, then you'll then to provide it on the commandline using -datadir or you can just use datadir=your/custom/path in the bitcoin.conf file.

Since it creates its own index, is there a reason why I should “carry” the entire blockchain?

It builds the index from the bitcoind blockchain, hence why you need it.

I don't think you can use systemd with WSL... you can however use it with WSL2: https://gist.github.com/djfdyuruiry/6720faa3f9fc59bfdf6284ee1f41f950

note that systemd is not entirely necessary to use ElectrumX... it's just a method for setting it up as a background service and autostart etc. You should be able to just "run" ElectrumX assuming you have the config etc setup correctly.

You can't use systemd on wsl, it's not given access to base hardware functions like that. I love using WSL, it's definitely the most convenient way I've found to SSH into another machine, VPS, and I even use it access my VirtualBox instances on the same host.

@BlackHatCoiner, you can install Ubuntu server onto VirtualBox, start the instance in "headless" mode, and access it with WSL. The advantage is that you can copy and paste commands right from your windows desktop without installing all the VirtualBox additions. I'll be a relatively light install without any bloat, and should work for your needs.

Also note worthy; ElectrumX requires bitcoin core to run unpruned, so you will have to download the entire blockchain.

In case anyone cares, here's how to set up a VirtualBox so you can ssh into it using WSL:

Obviously your VM needs to have SSH server installed, but you don't need to generate a key pair.

On your VM:

Code:

sudo apt install openssh-server

On your host, go to your vbox settings, click on network, on the "Adapter 1" tab click on Advanced to expand the field, and then click on the "Port Forwarding" button:

Create a rule as shown below. The host port isn't critical but choose something you're certain isn't being used by another service.

Now you'll be able to start your vbox in headless mode, open a WSL window, and connect using this command:

Code:

ssh -p 2200 @localhost

I found this tutorial on the internet and I think that he explains it simpler than on the one of github. I haven't worked on Bitcoin Core a lot, for example I've never used its command line program, and thus I'm getting an error I don't understand. By running ./bitcoin-cli --testnet getinfo on the terminal I should be getting information about my node (such as block height).

I have opened the Bitcoin Core application (using ./bitcoind --testnet) but once I run the above command I get:

Code:

angelo@angelo:~/bitcoin/bin$ ./bitcoin-cli -testnet -rpcuser=root -rpcpassword= getinfo

I admit defeat... I've been trying to run electrumx for my testnet bitcoin node but can't understand how it works! Is that HOWTO tutorial is too complicated or is it just me? I still haven't found out what is the running file.

Is this the part that should start my electrumx server? Because it returns me this when I enter “systemctl start electrumx”.:

Code:

System has not been booted with systemd as init system (PID 1). Can't operate.

I also haven't understood yet how it'll connect with my bitcoind. Is it written on the HOWTO and I've missed it? Need help. Lips sealed

Do you mean Ubuntu LTS which run though VirtualBox/WSL? It should work.

I mean the Ubuntu LTS that requires enabling the WSL. But, going through a virtual box seems better, I hadn't thought of it.

usually you need a fully synced, unpruned node, running with txindex=1... and you set the "network" type in electrumx and then point it at the appropriate data directory.

Since it creates its own index, is there a reason why I should “carry” the entire blockchain? Also, are these things detailed on the documentation or I should use the search button whenever I have a similar query? I just want to know if it's a complicated setup.

I also have bought a Windows VPS that isn't being used at the moment, so why not providing it to the electrum community?

Be wary of any storage, bandwidth or CPU caps that your VPS has... an Electrum server isn't necessarily "huge" in terms of requirements, but cheap VPSes often have relatively low caps.

I picked electrumx, because it's the most popular implementation. It seems that I can't install it on windows, only on unix. The thing is that I don't have an Ubuntu installed right now. Could this work with Windows 10 on an Ubuntu LTS?

Possibly... I've run other Electrum servers on WSL (ie. electrs) but it's obviously not ideal for performance reasons (and you're also doubling up on OS storage space requirements.)

Quote from: BlackHatCoiner on April 23, 2021, 03:42:43 AM

Is the same procedure if I want to run a testnet server? I don't have the storage for downloading the entire blockchain.

How does it return the balance of address(es) instantly? On Bitcoin Core it has to rescan the blockchain (which will take a lot of time).

you'll want to read up about SPV and bloom filters. Wink

but ElectrumX basically builds its own index of the blockchain

Quote from: BlackHatCoiner on April 23, 2021, 03:42:43 AM

Will I be shown on others' network servers? If no, how can I be shown?

Will generally depend on how you set it up and firewalls etc

I have been experimenting with electrum as a wallet since I learnt about bitcoin, a year ago, and I can admit that it's the simplest and most useful one. I'd like to run my own electrum server, but not for privacy reasons, just for exercise. I also have bought a Windows VPS that isn't being used at the moment, so why not providing it to the electrum community?

I picked electrumx, because it's the most popular implementation. It seems that I can't install it on windows, only on unix. The thing is that I don't have an Ubuntu installed right now. Could this work with Windows 10 on an Ubuntu LTS?

Other questions too:

Is the same procedure if I want to run a testnet server? I don't have the storage for downloading the entire blockchain.
How does it return the balance of address(es) instantly? On Bitcoin Core it has to rescan the blockchain (which will take a lot of time).
Will I be shown on others' network servers? If no, how can I be shown?
