环境
cpu架构：mips64
操作系统: CentOS 7
kernel版本：3.10.0-693.lns7.8.mips64el
docker： 18.06.3.ce
kubernetes: 1.15.9-0
部署准备
配置静态hosts解析
禁用selinux，防火墙，swap
[root@compute ~]# sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config [root@compute ~]# setenforce 0 [root@compute ~]# getenforce Disabled关闭firewalld
[root@compute ~]# systemctl status firewalld.service ● firewalld.service - firewalld - dynamic firewall daemon Loaded: loaded (/usr/lib/systemd/system/firewalld.service; disabled; vendor preset: enabled) Active: inactive (dead) Docs: man:firewalld(1)临时关闭swag
[root@master ~]# swapoff -a编辑/etc/fstab,禁用swap分区的挂载
[root@compute ~]# vim /etc/fstab #UUID=c5b3070e-4f41-4282-bf1c-359b90ebfbb7 swap swap defaults 0 0swappiness参数调整
[root@master ~]# vim /etc/sysctl.d/k8s.conf vm.swappiness=0 [root@master ~]# sysctl -p /etc/sysctl.d/k8s.confmaster和node节点安装以下软件包

只有一个节点，去除污点，让master也可以跑负载
kubectl taint node compute node-role.kubernetes.io/master-
