Hi!

sudo wget https://www.process-one.net/download...-installer.run
sudo mv downloads-action.php?file=%2Fejabberd%2F16.01%2Fejabberd-16.01-linux-x86_64-installer.run ejabberd-16.01-linux-x86_64-installer.run
sudo chmod +x ejabberd-16.01-linux-x86_64-installer.run
./ejabberd-16.01-linux-x86_64-installer.run
/home/dev/ejabberd/bin start

In browser:
