Requirements

• nodejs versions 8.x to 12.x are supported
• npm usually installed with nodejs
• Linux (though macos does works and Windows kind of works)
• xz (xz-utils apt package) to be able to download and extract updated Linux binaries
• setcap (libcap2-bin) to be enable coinevonet to not need to run as root on Linux

How to do a fresh service node install

This will use npm to install the launcher

sudo npm install -g coinevo-launcher

This will create any needed directories and make sure everything has the proper permissions to run as a specified user such as snode in this example

sudo coinevo-launcher set-perms snode

Now make sure sure you running the following commands as the user specified or you may run into permission problems (EPERM).

After it's installed, you can ask to prequalify your server to be a service node

coinevo-launcher prequal

you can also ask it to download the Coinevo binaries if you don't already have them

coinevo-launcher download-binaries

How to use without systemd

coinevo-launcher start

Running it once should start the suite of services into the background or give you a message why it can't

Running coinevo-launcher client, will give you an interactive terminal to coinevod (the copy running from the current directory if you have multiple). exit will stop your service node. If you just want to exit the interactive terminal, please use ctrl-c.

You can pass most command line parameters that you would give to coinevod to coinevo-launcher start

You can make a launcher config file in /etc/coinevo-launcher/launcher.ini and change various settings, Check our wiki for details on options.

How to keep the launcher up to date

Update your launcher without systemd

Stop your service node if it's running (you can use coinevo-launcher status to check)

coinevo-launcher stop

Update the launcher

sudo npm install -g coinevo-launcher

And be sure to make sure you restart your service node (if it's staked) by

coinevo-launcher start

Get the latest Coinevo software versions

coinevo-launcher download-binaries

And be sure to make sure you restart your service node (if it's staked) by

Software the launcher manages

• coinevod
• coinevonet
• coinevo-storage

To get the required software you can run coinevo-launcher download-binaries and they will be placed in /opt/coinevo-launcher/bin

You can download the coinevo binaries (faster) from each above page's release section

or

You can build from source. Make sure you select the correct repos/branches/versions as not all versions will work with each other.

And if you don't have the dependencies to build from source check out contrib/dependency_helper/
