4. RKE2 安装
设置一个 HA 集群需要以下步骤：
配置一个固定的注册地址
启动第一个 server 节点
加入其他 server 节点
加入 agent 节点
参考：https://docs.rancher.cn/docs/rke2/install/ha/_index/
注意：由于主机有限，我们就把第一个启动的节点设置为注册地址，下面只进行2、3步骤。
4.1 下载安装
rke2版本信息：https://github.com/rancher/rke2/releases
sudo mkdir /root/rke2-artifacts && cd /root/rke2-artifacts/
wget https://github.com/rancher/rke2/releases/download/v1.26.12%2Brke2r1/rke2-images.linux-amd64.tar.zst
wget https://github.com/rancher/rke2/releases/download/v1.26.12%2Brke2r1/rke2.linux-amd64.tar.gz
wget https://github.com/rancher/rke2/releases/download/v1.26.12%2Brke2r1/sha256sum-amd64.txt
curl -sfL https://get.rke2.io --output install.sh
安装
INSTALL_RKE2_ARTIFACT_PATH=/root/rke2-artifacts sh install.sh
输出：
$ INSTALL_RKE2_ARTIFACT_PATH=/root/rke2-artifacts sh install.sh
[INFO] staging local checksums from /root/rke2-artifacts/sha256sum-amd64.txt
[INFO] staging zst airgap image tarball from /root/rke2-artifacts/rke2-images.linux-amd64.tar.zst
[INFO] staging tarball from /root/rke2-artifacts/rke2.linux-amd64.tar.gz
[INFO] verifying airgap tarball
[INFO] installing airgap tarball to /var/lib/rancher/rke2/agent/images
[INFO] verifying tarball
[INFO] unpacking tarball file to /usr/local
启用 rke2-server 服务
systemctl enable rke2-server.service && systemctl start rke2-server.service
如有需要，可以查看日志
journalctl -u rke2-server -f
启动的过程可能需要3-8分钟，请耐心等候！
启动完成之后，你通过以下命令设置 kubectl 进行交互
设置环境变量
cat >>/root/.bashrc<< EOF
export KUBECONFIG=/etc/rancher/rke2/rke2.yaml PATH=$PATH:/var/lib/rancher/rke2/bin
EOF
source /root/.bashrc

4.2 配置其他管理节点
第一服务器节点建立秘密令牌，当连接到集群时，其他服务器或代理节点将向该秘密令牌注册。
要将自己的预共享密钥指定为令牌，请在启动时设置令牌参数。
如果您没有指定预共享密钥，RKE 2将生成一个并将其放置在/var/lib/rancher/rke 2/server/node-token中.
在rke2-master01 查看
