CentOS 7.6安装rancher V2.2.8 高可用集群

CentOS 7.6安装rancher V2.2.8 高可用集群

  • 使用GCP主机作为安装示例
[rke@rancher-1 ~]$ cat /etc/redhat-release
CentOS Linux release 7.6.1810 (Core)
用户名 主机名 内网IP 公网IP SSH端口
rke rancher-1 10.128.0.2 xxx 22
rke rancher-2 10.128.0.3 xxx 22
rke rancher-3 10.128.0.4 xxx 22
  1. 临时关闭selinux
sudo setenforce 0
  1. 永久关闭selinux
sudo  sed -i 's/SELINUX=enforcing/SELINUX=disabled/'  /etc/sysconfig/selinux
  1. 安装docker
sudo yum install -y yum-utils wget device-mapper-persistent-data lvm2

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

sudo yum install -y docker-ce-18.09.8 docker-ce-18.09.8 containerd.io

sudo usermod -aG docker ${USER}

sudo systemctl start docker

sudo systemctl enable docker
  1. 下载镜像
wget https://github.com/rancher/rke/releases/download/v0.2.8/rke_linux-amd64
sudo chmod 777 rke_linux-amd64 && sudo cp rke_linux-amd64 /usr/local/bin/rke
wget https://github.com/rancher/rancher/releases/download/v2.2.8/rancher-images.txt
wget https://github.com/rancher/rancher/releases/download/v2.2.8/rancher-save-images.sh
chmod 755 rancher-save-images.sh
#不运行docker save
sed -i 's/docker save/#docker save/g' rancher-save-images.sh
./rancher-save-images.sh
  1. 配置hosts,并测试ssh免密访问各个主机(rancher-1上安装的话，包括免密访问自己)
10.128.0.2  rancher-1
10.128.0.3  rancher-2
10.128.0.4  rancher-3

ssh rancher-1

  1. 下载helm

    wget https://get.helm.sh/helm-v2.14.3-linux-amd64.tar.gz
tar zxf helm-v2.14.3-linux-amd64.tar.gz
chmod +x ./linux-amd64/helm && sudo cp ./linux-amd64/helm /usr/local/bin/

  2. 下载kubectl

    # 有墙哦
# https://storage.googleapis.com/kubernetes-release/release/v1.14.5/bin/linux/amd64/kubectl
curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl
chmod +x ./kubectl && sudo cp ./kubectl /usr/local/bin/

  3. 初始化rke配置文件

nodes:
- address: 10.128.0.2
  #internal_address: 104.198.227.73
  user: rke
  role: [controlplane, etcd, worker]
  ssh_key_path: /home/rke/.ssh/id_rsa
- address: 10.128.0.3
  #internal_address: 35.232.38.212
  user: rke
  role: [controlplane, etcd, worker]
  ssh_key_path: /home/rke/.ssh/id_rsa
- address: 10.128.0.4
  #internal_address: 35.232.158.150
  user: rke
  role: [controlplane, etcd, worker]
  ssh_key_path: /home/rke/.ssh/id_rsa

services:
  etcd:
    snapshot: true
    creation: 6h
    retention: 24h
  1. 配置解析到各个节点, (如果节点有公网IP或者只打算内网访问，这样就可以了，否则就像官方文档那样，配置nginx代理吧), 例如：
rancher.xxx.top A 104.177.227.73
rancher.xxx.top A 35.111.38.212
rancher.xxx.top A 35.111.158.150
  1. rke安装集群

  1. 安装rancher chart
helm repo add rancher-stable https://releases.rancher.com/server-charts/stable
  1. 安装 cert manager
helm install stable/cert-manager \
--name cert-manager \
--namespace kube-system \
--version v0.5.2
  1. 安装rancher
helm install rancher-stable/rancher --name rancher --namespace cattle-system --set hostname=rancher.xxx.top

kubectl -n cattle-system get pod
  1. 安装完成啦，访问 Rancher-UI
(资料找到，但此问题会自行消失，admin用户已经被添加)
访问： https://rancher.xxx.top/ 为 admin账户设置初始密码，并登入系统。提示设置server-url，确保你的地址无误，确认即可。随后稍等一会儿，待系统完成初始化。
如果出现local集群一直停留在等待状态，并提示 Waiting for server-url setting to be set，可以尝试点击 全局->local->升级->添加一个成员角色（admin/ClusterOwner）->保存即可。
  1. 问题排查

  • 启动后local集群存在(v2.2.8)
