```

1.3.设置主机名

```shell
hostnamectl set-hostname k8s-master01
hostnamectl set-hostname k8s-master02
hostnamectl set-hostname k8s-master03
hostnamectl set-hostname k8s-node01

-e 's|^#baseurl=http://mirror.centos.org/$contentdir|baseurl=http://192.168.1.123/centos|g' \
-i.bak \
/etc/yum.repos.d/CentOS-*.repo




```

1.5.安装一些必备工具

```shell

```

1.7.关闭防火墙

```shell
systemctl disable --now firewalld
```

1.8.关闭SELinux

```shell
setenforce 0
sed -i 's#SELINUX=enforcing#SELINUX=disabled#g' /etc/sysconfig/selinux
```

1.9.关闭交换分区

```shell
sed -ri 's/.*swap.*/#&/' /etc/fstab
swapoff -a && sysctl -w vm.swappiness=0
cat /etc/fstab
# /dev/mapper/centos-swap swap                    swap    defaults        0 0
```

1.10.关闭NetworkManager 并启用 network

```shell
systemctl disable --now NetworkManager
systemctl start network && systemctl enable network
```

1.11.进行时间同步

```shell
服务端




yum install chrony -y
vim /etc/chrony.conf
cat /etc/chrony.conf | grep -v  "^#" | grep -v "^$"
pool ntp.aliyun.com iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcsync
allow 192.168.1.0/24
local stratum 10
keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony




systemctl restart chronyd
systemctl enable chronyd




客户端




yum install chrony -y
vim /etc/chrony.conf
cat /etc/chrony.conf | grep -v  "^#" | grep -v "^$"
pool 10.0.0.21 iburst
driftfile /var/lib/chrony/drift
makestep 1.0 3
rtcsync
keyfile /etc/chrony.keys
leapsectz right/UTC
logdir /var/log/chrony




systemctl restart chronyd ; systemctl enable chronyd






yum install chrony -y ; sed -i "s#2.centos.pool.ntp.org#10.0.0.21#g" /etc/chrony.conf ; systemctl restart chronyd ; systemctl enable chronyd






使用客户端进行验证




chronyc sources -v




```

1.12.配置ulimit

```shell
ulimit -SHn 65535
cat >> /etc/security/limits.conf <<EOF
* soft nofile 655360
* hard nofile 131072
* soft nproc 655350
* hard nproc 655350
* seft memlock unlimited
* hard memlock unlimitedd
EOF
```

1.13.配置免密登录

yum install -y sshpass
ssh-keygen -f /root/.ssh/id_rsa -P ''
export IP="192.168.1.76 192.168.1.77 192.168.1.78 192.168.1.79 192.168.1.80 192.168.1.86 192.168.1.87"
export SSHPASS=123123
for HOST in $IP;do
sshpass -e ssh-copy-id -o StrictHostKeyChecking=no $HOST
done
```

1.14.添加启用源

```shell
为 RHEL-8或 CentOS-8配置源
yum install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm




为 RHEL-7 SL-7 或 CentOS-7 安装 ELRepo
yum install https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm




查看可用安装包
yum  --disablerepo="*"  --enablerepo="elrepo-kernel"  list  available




```

1.15.升级内核至4.18版本以上

```shell
安装最新的内核
# 我这里选择的是稳定版kernel-ml   如需更新长期维护版本kernel-lt  
yum  --enablerepo=elrepo-kernel  install  kernel-ml




查看已安装那些内核
rpm -qa | grep kernel
kernel-core-4.18.0-358.el8.x86_64
kernel-tools-4.18.0-358.el8.x86_64
kernel-ml-core-5.16.7-1.el8.elrepo.x86_64
kernel-ml-5.16.7-1.el8.elrepo.x86_64
kernel-modules-4.18.0-358.el8.x86_64
kernel-4.18.0-358.el8.x86_64
kernel-tools-libs-4.18.0-358.el8.x86_64
kernel-ml-modules-5.16.7-1.el8.elrepo.x86_64






查看默认内核
grubby --default-kernel
/boot/vmlinuz-5.16.7-1.el8.elrepo.x86_64






若不是最新的使用命令设置
grubby --set-default /boot/vmlinuz-「您的内核版本」.x86_64




重启生效
reboot




整合命令为:
yum install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm -y ; yum  --disablerepo="*"  --enablerepo="elrepo-kernel"  list  available -y ; yum  --enablerepo=elrepo-kernel  install  kernel-ml -y ; grubby --default-kernel ; reboot
```

ip_vs_rr
ip_vs_wrr
ip_vs_sh
nf_conntrack
ip_tables
ip_set
xt_set

ipt_REJECT
ipip
EOF




systemctl restart systemd-modules-load.service




lsmod | grep -e ip_vs -e nf_conntrack

nf_defrag_ipv6         24576  2 nf_conntrack,ip_vs
nf_defrag_ipv4         16384  1 nf_conntrack
libcrc32c              16384  3 nf_conntrack,xfs,ip_vs
```

1.17.修改内核参数

```shell
cat <<EOF > /etc/sysctl.d/k8s.conf
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables = 1
fs.may_detach_mounts = 1
vm.overcommit_memory=1
vm.panic_on_oom=0
fs.inotify.max_user_watches=89100
fs.file-max=52706963
fs.nr_open=52706963
net.netfilter.nf_conntrack_max=2310720






net.ipv4.tcp_keepalive_time = 600
net.ipv4.tcp_keepalive_probes = 3
net.ipv4.tcp_keepalive_intvl =15
net.ipv4.tcp_max_tw_buckets = 36000
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_max_orphans = 327680
net.ipv4.tcp_orphan_retries = 3
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_max_syn_backlog = 16384
net.ipv4.ip_conntrack_max = 65536
net.ipv4.tcp_max_syn_backlog = 16384
net.ipv4.tcp_timestamps = 0
net.core.somaxconn = 16384
EOF




sysctl --system
```

1.18.所有节点配置hosts本地解析

```shell
cat > /etc/hosts <<EOF
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.76 k8s-master01
192.168.1.77 k8s-master02
192.168.1.78 k8s-master03
192.168.1.79 k8s-node01
192.168.1.80 k8s-node02
192.168.1.86 lb01
192.168.1.87 lb02
192.168.1.88 lb-vip

```

# 2.k8s基本组件安装

2.1.所有k8s节点安装Containerd作为Runtime

```shell
yum install containerd -y
```

2.1.1配置Containerd所需的模块

```shell
cat <<EOF | sudo tee /etc/modules-load.d/containerd.conf
overlay
br_netfilter
EOF
```

2.1.2加载模块

```shell
systemctl restart systemd-modules-load.service
```

2.1.3配置Containerd所需的内核

```shell
cat <<EOF | sudo tee /etc/sysctl.d/99-kubernetes-cri.conf
net.bridge.bridge-nf-call-iptables  = 1
net.ipv4.ip_forward                 = 1
net.bridge.bridge-nf-call-ip6tables = 1
EOF




# 加载内核




sysctl --system




```

2.1.4创建Containerd的配置文件

```shell
mkdir -p /etc/containerd
containerd config default | tee /etc/containerd/config.toml


修改Containerd的配置文件
vim /etc/containerd/config.toml


# 找到containerd.runtimes.runc.options,在其下加入SystemdCgroup = true


[plugins."io.containerd.grpc.v1.cri".containerd.runtimes.runc.options]
SystemdCgroup = true
[plugins."io.containerd.grpc.v1.cri".cni]


# 将sandbox_image默认地址改为符合版本地址


sandbox_image = "registry.cn-hangzhou.aliyuncs.com/google_containers/pause:3.6"


```

2.1.5启动并设置为开机启动

```shell
systemctl daemon-reload
systemctl enable --now


```

2.1.6配置crictl客户端连接的运行时位置

```shell
cat > /etc/crictl.yaml <<EOF
runtime-endpoint: unix:///run/containerd/containerd.sock
image-endpoint: unix:///run/containerd/containerd.sock
timeout: 10
debug: false
EOF
```

# 给脚本授权


chmod +x /etc/keepalived/check_apiserver.sh


```

5.1.6启动服务

```shell
systemctl daemon-reload
systemctl enable --now haproxy
systemctl enable --now keepalived
```

5.1.7测试高可用

```shell
# 能ping同




[root@k8s-node02 ~]# ping 192.168.1.88




# 能telnet访问




[root@k8s-node02 ~]# telnet 192.168.1.88 8443




# 关闭主节点,看vip是否漂移到备节点






```

# 6.k8s组件配置(区别于第4点)

所有k8s节点创建以下目录

```shell

# 10.安装CoreDNS

10.1以下步骤只在master01操作

10.1.1修改文件

```shell
cd /root/Kubernetes/CoreDNS/
sed -i "s#KUBEDNS_SERVICE_IP#10.96.0.10#g" coredns.yaml




cat coredns.yaml | grep clusterIP:
clusterIP: 10.96.0.10

service/kube-dns created






```

# 11.安装Metrics Server

11.1以下步骤只在master01操作

11.1.1安装Metrics-server

在新版的Kubernetes中系统资源的采集均使用Metrics-server,可以通过Metrics采集节点和Pod的内存、磁盘、CPU和网络的使用率

```shell
安装metrics server
cd /root/Kubernetes/metrics-server/




kubectl  create -f .




serviceaccount/metrics-server created
clusterrole.rbac.authorization.k8s.io/system:aggregated-metrics-reader created
clusterrole.rbac.authorization.k8s.io/system:metrics-server created
rolebinding.rbac.authorization.k8s.io/metrics-server-auth-reader created
clusterrolebinding.rbac.authorization.k8s.io/metrics-server:system:auth-delegator created
clusterrolebinding.rbac.authorization.k8s.io/system:metrics-server created
service/metrics-server created
deployment.apps/metrics-server created
apiservice.apiregistration.k8s.io/v1beta1.metrics.k8s.io created






```

11.1.2稍等片刻查看状态

```shell
kubectl  top node

# 12.集群验证

# 查看




kubectl  get pod
NAME      READY   STATUS    RESTARTS   AGE
busybox   1/1     Running   0          17s






```

12.2用pod解析默认命名空间中的kubernetes

```shell
kubectl get svc
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   17h






kubectl exec  busybox -n default -- nslookup kubernetes
3Server:    10.96.0.10
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local




Name:      kubernetes
Address 1: 10.96.0.1 kubernetes.default.svc.cluster.local






```

12.3测试跨命名空间是否可以解析

```shell
kubectl exec  busybox -n default -- nslookup kube-dns.kube-system
Server:    10.96.0.10
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local




Name:      kube-dns.kube-system
Address 1: 10.96.0.10 kube-dns.kube-system.svc.cluster.local






```

12.4每个节点都必须要能访问Kubernetes的kubernetes svc 443和kube-dns的service 53

```shell
telnet 10.96.0.1 443
Trying 10.96.0.1...
Connected to 10.96.0.1.
Escape character is '^]'.




telnet 10.96.0.10 53
Trying 10.96.0.10...
Connected to 10.96.0.10.
Escape character is '^]'.




curl 10.96.0.10:53
curl: (52) Empty reply from server




```
