K8S部署

先创建一个debian模板

https://cmd.dayi.ink/uploads/upload_78895650660d7632aff3fbcb21486a2b.png

选择iso

https://cmd.dayi.ink/uploads/upload_8df897882fe69fd0f064edca9ba7c049.png

快速安装一下即可：

安装完成克隆成模板：

Master节点

直接克隆一个就可以

https://cmd.dayi.ink/uploads/upload_a69e7a1dca5148c6f3d622dca14df4fd.png

克隆两个本地node

https://cmd.dayi.ink/uploads/upload_39e8d8e53fddbb693ee3d49adb0b45cc.png

https://cmd.dayi.ink/uploads/upload_bc570d7a6bc7a88a264b51d73f1520e8.png

sed -i 's/deb.debian.org/mirrors.ustc.edu.cn/g' /etc/apt/sources.list.d/debian.sources
sed -i 's|security.debian.org/debian-security|mirrors.ustc.edu.cn/debian-security|g' /etc/apt/sources.list
echo "export PATH=$PATH:/usr/sbin:/home/$(whoami)/.local/bin" >> ~/.bashrc
source ~/.bashrc
apt install ufw

apt install sudo vim wget curl -y

sudo hostnamectl set-hostname dayi-cloud-k8s-master

这里HOSTS用了tailscile 来进行相互访问

curl -fsSL https://tailscale.com/install.sh | sh

https://cmd.dayi.ink/uploads/upload_622bfea7593128a9dab2c1d503649f92.png

这样就配好hosts了

真男人直接下载：






修改主机名：


ssh-keygen -t ecdsa -b 256
ssh-copy-id node1
ssh-copy-id node2



复制密钥：
ssh-copy-id node2

复制hosts
scp /etc/hosts root@node1:/etc/hosts 
scp /etc/hosts root@node2:/etc/hosts 


修改内核配置
/etc/sysctl.conf
vi:
echo -e 'net.bridge.bridge-nf-call-iptables = 1 \nnet.bridge.bridge-nf-call-ip6tables = 1' >> /etc/sysctl.conf
开启模块
modprobe br_netfilter
ls /proc/sys/net/bridge/
echo "br_netfilter" > /etc/modules-load.d/br_netfilter.conf
sysctl -p

发送到从节点：
scp /etc/sysctl.conf root@node1:/etc/sysctl.conf
scp /etc/sysctl.conf root@node2:/etc/sysctl.conf 

#从节点执行：
modprobe br_netfilter
ls /proc/sys/net/bridge/
echo "br_netfilter" > /etc/modules-load.d/br_netfilter.conf
sysctl -p

防火墙 SELINUX：
systemctl stop firewalld
systemctl disable firewalld
systemctl status firewalld

setenforce 0
vi /etc/selinux/config
#修改： SELINUX=disabled

reboot
发送到从节点
scp /etc/selinux/config root@node1:/etc/selinux/config
scp /etc/selinux/config root@node2:/etc/selinux/config


查看SELINUX状态
sestatus
NTP时间同步
yum -y install wget ntpdate

crontab -e
*/1 * * * * /usr/sbin/ntpdate ntp1.aliyun.com

systemctl restart crond.service
添加源

vi /etc/yum.repos.d/kubernetes.repo
