### Linux

Find the architecture using the following command (example output given).
```
wget -q --show-progress --https-only --timestamping \
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/linux/cfssl \
https://storage.googleapis.com/kubernetes-the-hard-way/cfssl/1.4.1/linux/cfssljson
$ lscpu | grep -i 'model name\|arch'
Architecture: x86_64
Model name: AMD EPYC 7763 64-Core Processor
```

We could set the [version](https://github.com/cloudflare/cfssl/releases/tag/v1.6.5) and architecture as variables, download the tools and rename those.
```
VERSION="1.6.5"
ARCH="amd64"

wget -q --show-progress \
https://github.com/cloudflare/cfssl/releases/download/v${VERSION}/cfssl_${VERSION}_linux_${ARCH} \
https://github.com/cloudflare/cfssl/releases/download/v${VERSION}/cfssljson_${VERSION}_linux_${ARCH}

mv cfssl_${VERSION}_linux_${ARCH} cfssl
mv cfssljson_${VERSION}_linux_${ARCH} cfssljson
```

Make those binaries executable.
```
chmod +x cfssl cfssljson
```

Move them to the `/usr/local/bin` so that they could be run from anywhere on the system.
```
sudo mv cfssl cfssljson /usr/local/bin/
```
