Rancher 单节点安装部署记录

1. 环境准备
安装 Docker
# 查看已安装 docker
yum list installed | grep docker
# 卸载
yum remove -y \
containerd.io.x86_64 \
docker-ce.x86_64 \
docker-ce-cli.x86_64 \
docker-ce-rootless-extras.x86_64 \
docker-scan-plugin.x86_64

# 通过脚本安装
curl https://releases.rancher.com/install-docker/20.10.sh | sh

关闭防火墙 firewalld
关闭 SELinux
2. 安装 Rancher
启动 Rancher 服务

docker run -d --restart=unless-stopped \
-p 80:80 -p 443:443 \
--privileged \
rancher/rancher:v2.6.0

查看安装过程日志

docker ps | grep rancher | awk '{print $1}' | xargs docker logs -f

日志中有打印初始密码

2021/09/28 10:10:30 [INFO] -----------------------------------------
2021/09/28 10:10:30 [INFO] Welcome to Rancher
2021/09/28 10:10:30 [INFO] A bootstrap password has been generated for your admin user.
2021/09/28 10:10:30 [INFO]
2021/09/28 10:10:30 [INFO] Bootstrap Password: c66frm6dtlls945z4fw29kb9xkz66qxdrbbdxfpqghnpcp7c7pjkgq
2021/09/28 10:10:30 [INFO]
2021/09/28 10:10:30 [INFO] Use https://172.17.0.2/dashboard/?setup=c66frm6dtlls945z4fw29kb9xkz66qxdrbbdxfpqghnpcp7c7pjkgq to complete setup in the UI
2021/09/28 10:10:30 [INFO] -----------------------------------------

或者安装完成后筛选过滤该密码

docker logs container-id 2>&1 | grep "Bootstrap Password:"

打开浏览器 http://192.168.1.10 输入初始密码

设置新密码

创建集群

选择自定义集群

参数保持默认即可

勾选全部角色，复制命令

执行加入节点命令

sudo docker run -d --privileged --restart=unless-stopped --net=host \
-v /etc/kubernetes:/etc/kubernetes \
-v /var/run:/var/run rancher/rancher-agent:v2.6.0 \
--server https://192.168.1.10:443 \
--token d7ck5vm5lshgm98wzvznbsfbnrtqmgnl6g2sxnk85ll5psw7xs7vgg
--ca-checksum 413df4f04a0f00ffaa9b445431e76da26dbd678c21b4d5111cbedbbb37d14588 \
--etcd --controlplane --worker

等待时发现有报错

查看 etcd 日志，可能是网络不好，耐心等待

docker logs -f etcd

一段时间后所有服务均正常，至此安装结束

3. 卸载 Rancher
删除 Rancher 并清理
# 删除容器
docker rm -f $(sudo docker ps -aq);
# 删除卷
docker volume rm $(sudo docker volume ls -q);
# 卸载 kubelet 挂载目录
for m in $(sudo tac /proc/mounts | sudo awk '{print $2}' | sudo grep /var/lib/kubelet);do
sudo umount $m||true
done
# 卸载 rancher 挂载目录
for m in $(sudo tac /proc/mounts | sudo awk '{print $2}' | sudo grep /var/lib/rancher);do
sudo umount $m||true
done
# 删除相关目录
rm -rf /etc/cni \
/etc/kubernetes \
/opt/cni \
/opt/rke \
/run/secrets/kubernetes.io \
/run/calico \
/run/flannel \
/var/lib/calico \
/var/lib/etcd \
/var/lib/cni \
/var/lib/kubelet \
/var/lib/rancher \
/var/log/containers \
/var/log/pods \
/var/run/calico

rm -f /var/lib/containerd/io.containerd.metadata.v1.bolt/meta.db
sudo systemctl restart containerd
sudo systemctl restart docker
