Linux环境设置

host设置

10.6.208.11 zy-k8s-11
10.6.208.12 zy-k8s-12
10.6.208.13 zy-k8s-13

ntp设置

yum install -y ntp wget
echo "server ntp1.aliyun.com" >> /etc/ntp.conf

修改内核参数

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

应用内核参数

sysctl --system

关闭swap空间

swapoff -a
yes | cp /etc/fstab /etc/fstab_bak
cat /etc/fstab_bak |grep -v swap > /etc/fstab

关闭SELinux

setenforce 0
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

安装完高版本Docker(1.13以后版本安装完会将iptables默认转发策略切换为DROP)切换防火墙默认转发策略为ACCEPT

iptables -P FORWARD ACCEPT

其他方法可参考：kubernetes issues#40182

至此设置完成。
