**一、安装rpm 包**

rpm 制作过程参考上一节（[https://blog.csdn.net/yulei\_qq/article/details/89205022][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 <<EOF >  /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。
