total used free shared buff/cache available
Mem: 10376 943 8875 11 557 9178
Swap: 0 0 0
6.修改内核参数并重载
[root@node1-190 ~]# cat >> /etc/sysctl.d/k8s.conf << EOF
vm.swappiness=0
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
net.ipv4.ip_forward = 1
EOF
[root@node1-190 ~]# modprobe br_netfilter && modprobe overlay && sysctl -p /etc/sysctl.d/k8s.conf
vm.swappiness = 0
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1

六.集群初始化
1.下载k8s所需软件(各个节点都做)
[root@node4-193 ~]# cat << EOF> /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled=1
gpgcheck=0
repo_gpgcheck=0
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg
https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
EOF
[root@node4-193 ~]# yum install kubeadm kubectl kubelet -y
[root@node1-190 ~]# systemctl start kubelet
2.拉取所需镜像(各个节点做)
(1)有自建harbor情况
[root@node1-190 ~]# vim dockerimages.sh
#!/bin/bash
images=$(kubeadm config images list --kubernetes-version=1.28.0 | awk -F '/' '{print $NF}')
for i in ${images}
do
docker pull registry.aliyuncs.com/google_containers/$i
docker tag registry.aliyuncs.com/google_containers/$i node5-196.com/google_containers/$i #需要修改为刚创建的harbor的仓库地址
docker push node5-196.com/google_containers/$i
docker rmi registry.aliyuncs.com/google_containers/$i
done
[root@node1-190 ~]# docker login node5-196.com

(2)无harbor情况
#没有自建情况
[root@node1-190 ~]# vim dockerimages.sh
#!/bin/bash
images=$(kubeadm config images list --kubernetes-version=1.28.0 | awk -F '/' '{print $NF}')
for i in ${images}
do
docker pull registry.aliyuncs.com/google_containers/$i
docker tag registry.aliyuncs.com/google_containers/$i node5-196.com/google_containers/$i
docker push registry.aliyuncs.com/google_containers/$i
docker rmi registry.aliyuncs.com/google_containers/$i
done
3.master节点初始化 (只在master节点做)
执行完脚本无误后执行以下命令
#master节点做,有自建harbor情况
kubeadm init --kubernetes-version=1.28.2 \ #一定要是真实版本
--apiserver-advertise-address=192.168.2.190 \ #自己master节点的IP
--image-repository node5-196.com/google_containers \ #镜像地址,自建harbor就写harbor的地址,没有就用阿里云的
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors=Swap \
--cri-socket=unix:///var/run/cri-dockerd.sock
#没harbor情况
kubeadm init --kubernetes-version=1.28.2 \
--apiserver-advertise-address=192.168.2.180 \
--image-repository registry.aliyuncs.com/google_containers \
--service-cidr=10.96.0.0/12 \
--pod-network-cidr=10.244.0.0/16 \
--ignore-preflight-errors=Swap \
--cri-socket=unix:///var/run/cri-dockerd.sock
4.执行成功后出现此界面后进行权限设置
# master节点为普通用户时
[root@node1-190 ~]# mkdir -p $HOME/.kube && cp -i /etc/kubernetes/admin.conf $HOME/.kube/config && chown $(id -u):$(id -g) $HOME/.kube/config
# master节点为root用户时
[root@node1-190 ~]# export KUBECONFIG=/etc/kubernetes/admin.conf
5.各个节点根据master初始化成功后的参数来加入(各个节点都做)
kubeadm join 192.168.2.190:6443 --token m5mkth.rb2e9rb3892fsu37 \
--discovery-token-ca-cert-hash sha256:1209d580742d411fb4406953185ef9f27522b3ba150b8726fd39f364628d0942 \
--cri-socket=unix:///var/run/cri-dockerd.sock
#注意:初始化完成后弹出的加入节点命令在节点上执行时会报找不到socket文件,手动指定自己的socket文件“--cri-socket=unix:///var/run/cri-dockerd.sock”
出现此界面即成功
[root@node1-190 ~]# kubectl get nodes
NAME STATUS ROLES AGE VERSION
node1-190.com Ready control-plane 121m v1.28.1
node2-191.com Ready <none> 104m v1.28.1
node3-192.com Ready <none> 96m v1.28.1
node4-193.com Ready <none> 11m v1.28.1
node5-196.com Ready <none> 9s v1.28.1
七.收尾工作(master节点做)
1.命令补全配置
[root@node1-190 ~]# echo "source <(kubectl completion bash)" >> ~/.bashrc && echo "source <(kubeadm completion bash)" >> ~/.bashrc && source ~/.bashrc
2.网络配置
(1)flannel
链接:https://pan.baidu.com/s/1TRUyPxbBZRcyyyqojquhBw
提取码:wvap
[root@node1-190 ~]# vim flannel.sh
#!/bin/bash
for i in $(grep image kube-flannel.yml | grep -v '#' | awk -F '/' '{print $NF}')
do
docker pull flannel/$i
docker tag flannel/$i node5-196.com/google_containers/$i #需要修改为刚创建的harbor的仓库地址
docker push node5-196.com/google_containers/$i
docker rmi flannel/$i
done
#注意:如果没有自建harbor,需要将node5-196.com改为registry.aliyuncs.com,后面的内容都如此
