这里个人觉得可以和kubeadm的步骤一致，不过还是按照1.2配置的官方要求
1、关闭防火墙
systemctl stop firewalld && systemctl disable firewalld2、为iptables设置空规则
yum -y install iptables-services && systemctl start iptables && systemctl enable iptables&& iptables -F && service iptables save3、关闭SELINUX
swapoff -a && sed -i '/ swap / s/^(.*)$/#1/g' /etc/fstabsetenforce 0 && sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config 1.2 官方提供1、创建一个新用户（之后将用来运行docker，尽量不要用root用户）
useradd lurious2、将新创建的用户加入到docker组中，为了可以运行docker
usermod -aG docker lurious3、关闭swap 分区
swapoff -a4、执行以下的脚本
for module in br_netfilter ip6_udp_tunnel ip_set ip_set_hash_ip ip_set_hash_net iptable_filter iptable_nat iptable_mangle iptable_raw nf_conntrack_netlink nf_conntrack nf_conntrack_ipv4 nf_defrag_ipv4 nf_nat nf_nat_ipv4 nf_nat_masquerade_ipv4 nfnetlink udp_tunnel veth vxlan x_tables xt_addrtype xt_conntrack xt_comment xt_mark xt_multiport xt_nat xt_recent xt_set xt_statistic xt_tcpudp; do if ! lsmod | grep -q $module; then echo "module $module is not present"; fi; done5、更改sysctl设置
vi /etc/sysctl.conf net.ipv4.ip_forward = 1net.bridge.bridge-nf-call-ip6tables = 1# 官方中要求的net.bridge.bridge-nf-call-iptables = 16、开启6443端口（使用iptables）
以下语句执行一个就可以
# Open TCP/6443 for alliptables -A INPUT -p tcp --dport 6443 -j ACCEPT# Open TCP/6443 for one specific IPiptables -A INPUT -p tcp -s your_ip_here --dport 6443 -j ACCEPT7、开启6443端口（使用firewalld）
# Open TCP/6443 for allfirewall-cmd --zone=public --add-port=6443/tcp --permanentfirewall-cmd --reload# Open TCP/6443 for one specific IPfirewall-cmd --permanent --zone=public --add-rich-rule=' rule family="ipv4" source address="your_ip_here/32" port protocol="tcp" port="6443" accept'firewall-cmd --reload8、允许TCP
AllowTcpForwarding yes9、设置SSH（在RKE所在的宿主机上执行）
一路空格就行
ssh-keygen10、将所生成的密钥的公钥分发到各个节点
ssh-copy-id lurious@192.168.109.10ssh-copy-id lurious@192.168.109.11ssh-copy-id lurious@192.168.109.12 二、使用RKE（Rancher kubernetes engine)部署Kubernetes 2.1、查看版本 ./rke version 2.2 、rke配置文件 # If you intened to deploy Kubernetes in an air-gapped environment,# please consult the documentation on how to configure custom RKE images.# 配置harbor仓库信息private_registries: -
