On RedHat and CentOS

In RedHat derived distributions, you can use the official Crystal repository.

Setup repository

First you have to add the repository to your YUM configuration. For easy setup just run in your command line:

curl https://dist.crystal-lang.org/rpm/setup.sh | sudo bash

That will add the signing key and the repository configuration. If you prefer to do it manually execute:

rpm --import https://dist.crystal-lang.org/rpm/RPM-GPG-KEY

cat > /etc/yum.repos.d/crystal.repo <<END
[crystal]
name = Crystal
baseurl = https://dist.crystal-lang.org/rpm/
END

Install

Once the repository is configured you're ready to install Crystal:

sudo yum install crystal

Upgrade

When a new Crystal version is released you can upgrade your system using:

sudo yum update crystal
