Kubernetes1.14 学习笔记二: 安装K8S

一、安装rpm 包

   rpm 制作过程参考上一节（https://blog.csdn.net/yulei_qq/article/details/89205022）

   运行如下命令:

[root@k8s x86_64]#   yum localinstall  *.rpm 

.............

Installed:
  kubeadm.x86_64 0:1.14.1-0       kubectl.x86_64 0:1.14.1-0       kubelet.x86_64 0:1.14.1-0       kubernetes-cni.x86_64 0:0.7.5-0      

Dependency Installed:
  conntrack-tools.x86_64 0:1.4.4-4.el7        libnetfilter_cthelper.x86_64 0:1.0.0-9.el7   libnetfilter_cttimeout.x86_64 0:1.0.0-6.el7  
  libnetfilter_queue.x86_64 0:1.0.2-2.el7_2   socat.x86_64 0:1.7.3.2-2.el7                

Complete!

     设置开机启动  

 systemctl enable --now kubelet

  注意： 

• Setting SELinux in permissive mode by running setenforce 0 and sed ... effectively disables it. This is required to allow containers to access the host filesystem, which is needed by pod networks for example. You have to do this until SELinux support is improved in the kubelet.

• Some users on RHEL/CentOS 7 have reported issues with traffic being routed incorrectly due to iptables being bypassed. You should ensure net.bridge.bridge-nf-call-iptables is set to 1 in your sysctl config, e.g.

  cat <  /etc/sysctl.d/k8s.conf
  net.bridge.bridge-nf-call-ip6tables = 1
  net.bridge.bridge-nf-call-iptables = 1
  EOF
  sysctl --system

• Make sure that the br_netfilter module is loaded before this step. This can be done by running lsmod | grep br_netfilter. To load it explicitly call modprobe br_netfilter.

  kubelet现在每隔几秒钟就重新启动一次，因为它在崩溃循环中等待kubeadm告诉它该做什么。
