Requirements

Install

First take a look at the script integration README to know a few facts ant tips that will help you to understand how Skywire is integrated to the Unix systems, very important is the part of the Network Policies.

Now if you read that you must realize that if you use a different IP set you will need to change a few things, we will point them out when needed.

Unix systems

mkdir -p $GOPATH/src/github.com/skycoin
cd $GOPATH/src/github.com/skycoin
git clone https://github.com/skycoin/skywire.git

Build the binaries for skywire

cd $GOPATH/src/github.com/skycoin/skywire/cmd
go install ./...

Set the IP of the manager

If you are using the default network IP set you are set, follow to the next step.

If you uses a different IP set you need to modify the file in static/script/skywire.defaults, in particular the variable called MANAGER_IP in the default file it points to the default manager IP, in the case of a different IP set this will need to be changed to the manager IP.

Just for a matter of precaution, after modify this file be sure that there isn't a fille called /etc/default/skywire if it's there erase it. It will be updated once you run skywire.

Run Skywire

Unix systems

Run Skywire Manager

cd $GOPATH/bin
./skywire-manager -web-dir ${GOPATH}/src/github.com/skycoin/skywire/static/skywire-manager

tip: If you run with the above command, you will not be able to close the current window or you will close Skywire Manger.

If you need to close the current window and continue to run Skywire Manager, you can use

cd $GOPATH/bin
nohup ./skywire-manager -web-dir ${GOPATH}/src/github.com/skycoin/skywire/static/skywire-manager > /dev/null 2>&1 &sleep 3

Note: do not execute the above two commands at the same time, just select one of them.

Run Skywire Node

Open a new command window

cd $GOPATH/bin
./skywire-node -connect-manager -manager-address 127.0.0.1:5998 -manager-web 127.0.0.1:8000 -discovery-address testnet.skywire.skycoin.com:5999-028ec969bdeb92a1991bb19c948645ac8150468a6919113061899051409de3f243 -address :5000 -web-port :6001 

tip: If you run with the above command, you will not be able to close the current window or you will close Skywire Node.

If you need to close the current window and continue to run Skywire Manager, you can use

cd $GOPATH/bin
nohup ./skywire-node -connect-manager -manager-address :5998 -manager-web :8000 -discovery-address testnet.skywire.skycoin.com:5999-028ec969bdeb92a1991bb19c948645ac8150468a6919113061899051409de3f243 -address :5000 -web-port :6001 > /dev/null 2>&1 &cd /

Stop Skywire Manager and Node.

  1. If the Skywire Manager and Node are started by using the terminal window, please press Ctrl + c on the respective terminal of Manager and Node.

  2. Use the shutdown terminal to keep running, please enter:

Stop Skywire Manager
cd $GOPATH/bin
pkill -F manager.pid
Stop Skywire Node
cd $GOPATH/bin
pkill -F node.pid

Run Skywire Manager

Open a command window on a PC that will act like a manager and follow the install procedure, then to start a node do this:

${GOPATH}/src/github.com/skycoin/skywire/static/script/manager_start

tip: the manager start script will also run a local node, you don't need to run in manually on the manager.

Run Skywire Node

Open a command window on a node only computer and follow the install procedure, then to start a node:

${GOPATH}/src/github.com/skycoin/skywire/static/script/node_start

tip: the node is instructed to connect to the manager IP automatically, if you use a non default IP set you must check the file "/etc/default/skywire" and change the MANAGER_IP variable on each Pc of your setup.

This two files are the default start script for skywire services, take a peek on them to know more if yu are interested.

Stop Skywire Manager and Node.

If you started the manager and the nodes by the ways stated above you can stop them on each Pc by this command on a console:

${GOPATH}/src/github.com/skycoin/skywire/static/script/stop

This will check for the pid of the running processes and kill them. If you ran them by hand using a call to a the specific manager or node binaries this will not stop them, in this case you must run this:

killall node
killall manager
Installing the manager and node as a service using systemd

If you use a modern Linux OS (released after 2017) you are using systemd as init manager, skywire has the files needed to make them a service inside systemd.

Please note that the manager instance will start also a local node, so you must select just a manager on a net and the rest will be nodes.

Installing & start of mananger unit file on systemd
cp ${GOPATH}/src/github.com/skycoin/skywire/static/script/upgrade/data/skywire-manager.service /etc/systemd/system/
systemctl enable skywire-manager
systemctl start skywire-manager
Installing & start of nodes unit file on systemd
cp ${GOPATH}/src/github.com/skycoin/skywire/static/script/upgrade/data/skywire-node.service /etc/systemd/system/
systemctl enable skywire-node
systemctl start skywire-node

From this point forward you can user this services to start/stop your skywire instances via systemd commands:

# for the nodes
systemctl *start* skywire-node
systemctl *stop* skywire-node
systemctl *status* skywire-node
# for the manager
systemctl *start* skywire-manager
systemctl *stop* skywire-manager
systemctl *status* skywire-manager

Open Skywire Manager View

Open http://localhost:8000. The default login password for Skywire manager is 1234.

Connect to node

  1. Connect to node —— Search services —— Connect

  2. Connect to node —— Enter the key for node and app —— Connect

In the first way, you can search for nodes around the world, and select the nodes you want to connect to; The second way is to connect to the specified node.

Use Skywire App

After the default normal start, the App will display "** available port **" (e.g. 9443) after successful connection.

Use Firefox Browser

Install FoxyProxy Standard

Open Firefox Browser,address bar input"https://addons.mozilla.org/zh-CN/firefox/addon/foxyproxy-standard/", Click "add to Firefox" button to follow the prompts to install.

Download System Images

Note: these images can only be run on Orange Pi Prime.

Skyflash & Skybian

We developed our own custom flashing tool that prepares & flashes our custom OS Skybian for operation on our Skyminers. Skybian is our custom OS built upon armbian. It comes with Skywire and its dependencies preinstalled and its IP configuration is adjusted by Skyflash according to your network environment. Please refer to the installation guide on our wiki for more details & instructions.

Official Skyminer Skybian Images

We are hosting eight (8) prepared Skybian images which are ready to use, i.e. you only need to flash them. They come with the default official Skyminer IP ranges:

  • manager: 192.168.0.2
  • node 1: 192.168.0.3
  • node 2: 192.168.0.4
  • node 3: 192.168.0.5
  • node 4: 192.168.0.6
  • node 5: 192.168.0.7
  • node 6: 192.168.0.8
  • node 7: 192.168.0.9

In case you cannot operate the official Skyminer in its default IP configuration you must use Skyflash to change the IP addresses on the images.

The images are hosted here. Make sure to select the most recent Skybian version, please refer to the Skybian releases.
