k8s的集群搭建

关闭防火墙：systemctl disable firewalld #永久关闭
关闭selinux:sed -i ‘s/enforcing/disabled’ /etc/selinux/config
关闭swap:sed -ri ‘s/.swap./#&/’ /etc/fstab
设置hostname:hostnamectl set -hostname k8smaster

在master添加hosts:`

cat >> /etc/host << EOF 
192.168.3.215 k8smaster
192.168.163.142 k8snode1
192.168.163.143 k8snode2
EOF

`
将ipv4的流量传递到iptables

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

sysctl --system #生效

#时间同步
yum install ntpdate -y
ntpdate time.window.com
