所有节点设置 ipvs 模块,在内核 4.19+版本中 nf_conntrack_ipv4 已经改成 nf_conntrack, 4.18 以下使用 nf_conntrack_ipv4 即可:
modprobe -- ip_vs
modprobe -- ip_vs_rr

modprobe -- ip_vs_sh
modprobe -- nf_contrack

Kubernetes 组件安装
docker 安装
# 安装docker所需的工具
yum install -y yum-utils device-mapper-persistent-data lvm2
# 配置阿里云的docker源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 指定安装这个版本的docker-ce
yum install -y docker-ce-18.09.9-3.el7
# 启动docker
systemctl enable docker && systemctl start docker
- docker 加速
创建 /etc/docker/daemon.json
由于新版 kubelet 建议使用 systemd,所以可以把 docker 的 CgroupDriver 改成 systemd
cat > /etc/docker/daemon.conf << EOF
{
"registry-mirrors": ["https://yp8sluaa.mirror.aliyuncs.com"]
}
EOF
- 设置开启启动
sudo systemctl daemon-reload
sudo systemctl restart docker
systemctl enable docker
- 查看 docker 信息
docker info
安装 k8s v1.16.0 master 管理节点
如果还没安装 docker，请参照本文步骤二安装 docker-ce 18.09.9（所有机器）安装。如果没设置 k8s 环境准备条件，请参照本文步骤三设置 k8s 环境准备条件（所有机器）执行。
以上两个步骤检查完毕之后，继续以下步骤。
安装 kubeadm、kubelet、kubectl 由于官方 k8s 源在 google，国内无法访问，这里使用阿里云 yum 源
# 执行配置k8s阿里云源
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
# 安装kubeadm、kubectl、kubelet
yum install -y kubectl-1.16.0-0 kubeadm-1.16.0-0 kubelet-1.16.0-0
# 启动kubelet服务
systemctl enable kubelet && systemctl start kubelet
初始化 k8s 以下这个命令开始安装 k8s 需要用到的 docker 镜像，因为无法访问到国外网站，所以这条命令使用的是国内的阿里云的源(registry.aliyuncs.com/google_containers)。另一个非常重要的是：这里的--apiserver-advertise-address 使用的是 master 和 node 间能互相 ping 通的 ip，我这里是 192.168.99.104，刚开始在这里被坑了一个晚上，你请自己修改下 ip 执行。这条命令执行时会卡在[preflight] You can also perform this action in beforehand using ''kubeadm config images pull，大概需要 2 分钟，请耐心等待。
# 下载管理节点中用到的6个docker镜像，你可以使用docker images查看到
# 这里需要大概两分钟等待，会卡在[preflight] You can also perform this action in beforehand using ''kubeadm config images pull
kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.16.0 --apiserver-advertise-address 192.168.99.104 --pod-network-cidr=10.244.0.0/16 --token-ttl 0
上面安装完后，会提示你输入如下命令，复制粘贴过来，执行即可。
# 上面安装完成后，k8s会提示你输入如下命令，执行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
记住 node 加入集群的命令 上面 kubeadm init 执行成功后会返回给你 node 节点加入集群的命令，等会要在 node 节点上执行，需要保存下来，如果忘记了，可以使用如下命令获取。
kubeadm token create --print-join-command
以上，安装 master 节点完毕。可以使用 kubectl get nodes 查看一下，此时 master 处于 NotReady 状态，暂时不用管。
安装 k8s v1.16.0 node 工作节点
如果还没安装 docker，请参照本文步骤二安装 docker-ce 18.09.9（所有机器）安装。如果没设置 k8s 环境准备条件，请参照本文步骤三设置 k8s 环境准备条件（所有机器）执行。
以上两个步骤检查完毕之后，继续以下步骤。
安装 kubeadm、kubelet
# 执行配置k8s阿里云源
cat <<EOF > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
# 安装kubeadm、kubectl、kubelet
yum install -y kubeadm-1.16.0-0 kubelet-1.16.0-0
# 启动kubelet服务
systemctl enable kubelet && systemctl start kubelet
加入集群 这里加入集群的命令每个人都不一样，可以登录 master 节点，使用 kubeadm token create --print-join-command 来获取。获取后执行如下。
kubeadm join 192.168.99.104:6443 --token ncfrid.7ap0xiseuf97gikl \
--discovery-token-ca-cert-hash sha256:47783e9851a1a517647f1986225f104e81dbfd8fb256ae55ef6d68ce9334c6a2
加入成功后，可以在 master 节点上使用 kubectl get nodes 命令查看到加入的节点。
安装 flannel（master 机器）
以上步骤安装完后，机器搭建起来了，但状态还是 NotReady 状态，如下图，master 机器需要安装 flanneld。 下载官方 fannel 配置文件 使用 wget 命令，地址为：(raw.githubusercontent.com/coreos/flan…
安装 fannel
kubectl apply -f kube-flannel.yml
大功告成
至此，k8s 集群搭建完成，如下图节点已为 Ready 状态，大功告成，完结撒花。
附录
这是 kube-flannel.yml 文件的内容，已经将无法访问的地址(quay.io)全部改为国内可以访问的地址(quay-mirror.qiniu.com)。我们新建一个 kube-flannel.yml 文件，复制粘贴该内容即可。
