Run AVA Labs Node Cascade (Ubuntu 19.10)
First you need to create a VPS server. I will tell an example of Google Cloud Platform.
Technical requirements:
- Hardware: 2 CPU, RAM > 4 GB, Storage > 20 GB free space.
- OS: Ubuntu 18.04, 19.10 or 20.04 version
- Mac OS X >= Catalina.
- Software: Go = 1.13.08
Initial setup
The following tools and libraries must be installed on the server:
libssl-dev
libuv1-dev
cmake
make
curl
g++/clang++ that supports c++14 (to build salticidae C++ library)
To install them, run the following command:
sudo apt-get install curl build-essential libssl-dev libuv1-dev cmake make g++
In order for the console to pull up the archive by the url and deploy it, install the CURL:
sudo apt install curl
Now install GIT so that you can install the github repositories:
sudo apt install git
Now update the system:
sudo apt update
GO installation:
Download the 1.13.8 version of the archive with Go tools and unpack it according to the given path:
cd ~
curl -O https://dl.google.com/go/go1.13.8.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.13.8.linux-amd64.tar.gz
Set the variables for the Go environment by opening the profile file:
nano .profile
This is how it looks:
Now add at the bottom of this file variables (should look like in the screenshot below):
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOPATH/bin:/usr/local/go/bin
Now you need to save and exit the file. Use keyboard shortcuts ctrl+s and ctrl+x.
To apply configuration changes, you need to update the system settings with the command:
source .profile
We do the same with the .bash_profile file. Open it for editing:
nano .bash_profile
Now add at the bottom of this file variables (should look like in the screenshot below):
export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
Now you need to save and exit the file. Use keyboard shortcuts ctrl+s and ctrl+x.
To apply configuration changes, you need to update the system settings with the command:
source .bash_profile
The last file to which we add the variables is .bashrc. Let's open it:
nano ~/.bashrc
Now add at the bottom of this file variables (should look like in the screenshot below):
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOPATH/bin:/usr/local/go/bin
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOBIN
Save and exit the file. Use keyboard shortcuts ctrl+s and ctrl+x.
To apply configuration changes, you need to update the system settings with the command:
source .bashrc
To check if the GO is installed correctly, use the command:
go
If you get the result as in the screenshot below, then you set everything correctly:
Install Gecko
Download the Gecko repository:
go get -v -d github.com/ava-labs/gecko/…
Duration of installation is from 3 to 10 minutes.
Now we’ll go to the Gecko directory and run the script that will configure everything:
cd $GOPATH/src/github.com/ava-labs/gecko
./scripts/build.sh
In order to make sure that everything went well, you need to run the following script:
./scripts/build_test.sh
If the test passed as in the screenshot below, then you are ready to launch the AVA test network.
RUN A NODE
To start launching a node, use the following script:
./build/ava
If you have everything as in the screenshot above, then everything is fine and the node is running.
Now it should be synchronized (do not disconnect the terminal). If lines with an error appear in orange text periodically, but new lines appear at the same time, this is normal.
If you close the terminal, the node will stop! To restart, enter the following commands:
cd $GOPATH/src/github.com/ava-labs/gecko
./build/ava
You can use Ctrl + C to kill the node.
If you do not want to keep the terminal open so that the node is running, you can use the ‘Screen’. After installing and configuring it, you can close the terminal and the node will not stop.
How to configure Screen: https://help.ubuntu.com/community/Screen
If your node has already been installed and updates have been released, they can be installed with the following commands:
source .bashrc
cd go/src/github.com/ava-labs/gecko
git pull && bash
./scripts/build.sh
If during the start node you encounter any problems or errors, you can contact the AVA developers in the official Discord server.
