Install Gaia

This guide will explain how to install the gaiad and gaiacli entrypoints onto your system. With these installed on a server, you can participate in the mainnet as either a Full Node or a Validator.

Install Go

Install go by following the official docs. Remember to set your $GOPATH and $PATH environment variables, for example:

mkdir -p $HOME/go/bin
echo "export GOPATH=$HOME/go" >> ~/.bash_profile
echo "export PATH=\$PATH:\$GOPATH/bin" >> ~/.bash_profile
source ~/.bash_profile

::: tip Go 1.12+ is required for the Cosmos SDK. :::

Install the binaries

Next, let's install the latest version of Gaia. Make sure you git checkout the correct released version.

::: warning For the mainnet, make sure your version is greater than v0.33.0 :::

::: warning Older releases up to 0.34.x are available from the Cosmos SDK releases page. :::

mkdir -p $GOPATH/src/github.com/cosmos
cd $GOPATH/src/github.com/cosmos
git clone -b <latest-release-tag> https://github.com/cosmos/gaia
cd gaia && make install

NOTE: If you have issues at this step, please check that you have the latest stable version of GO installed.

That will install the gaiad and gaiacli binaries. Verify that everything is OK:

$ gaiad version --long
$ gaiacli version --long

gaiacli for instance should output something similar to:

cosmos-sdk: 0.33.0
git commit: 7b4104aced52aa5b59a96c28b5ebeea7877fc4f0
build tags: netgo ledger
go version go1.12 linux/amd64

Build Tags

Build tags indicate special features that have been enabled in the binary.

Build Tag	Description
netgo	Name resolution will use pure Go code
ledger	Ledger devices are supported (hardware wallets)

Install binary distribution via snap (Linux only)

Do not use snap at this time to install the binaries for production until we have a reproducible binary system.

Developer Workflow

To test any changes made in the SDK or Tendermint, a replace clause needs to be added to go.mod providing the correct import path.

• Make appropriate changes
• Add replace github.com/cosmos/cosmos-sdk => /path/to/clone/cosmos-sdk to go.mod
• Run make clean install or make clean build
• Test changes

Next

Now you can join the mainnet, the public testnet or create you own testnet
