准备工作
1、主机配置
[root@k8s-master01 ~]# hostnamectl set-hostname k8s-master01
[root@k8s-master01 ~]# hostname
k8s-master01
[root@localhost ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.0.109 k8s-master01
192.168.0.108 k8s-node1
192.168.0.107 k8s-node2
192.168.0.105 k8s-node3
systemctl stop firewalld && systemctl disable firewalld
setenforce 0 && sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config
sestatus #查看selinux 状态
# 时间同步
ntpdate time1.aliyun.com
2、升级内核
导elrepo gpg key,软件验证
# rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
安装elrepoYUM源仓库
# yum -y install https://www.elrepo.org/elrepo-release-7.0-4.el7.elrepo.noarch.rpm
安装kernel-ml版本，ml为长期稳定版本，1t为长期维护版本
# yum --enablerepo="elrepo-kernel" -y install kernel-lt.x86_64
设置grub2默认引导为0，就是重启后会使用最新内核
# grub2-set-default 0
重新生成grub2引导文件
# grub2-mkconfig -o /boot/grub2/grub.cfg
更新后，需要重启，使用升级的内核生效。
#reboot 重启后检查版本
# uname -r
[root@k8s-master01 ~]# uname -r
5.4.265-1.el7.elrepo.x86_64
3、配置内核转发以及过滤
添加网桥过滤及内核转发配置文件
cat > /etc/sysctl.d/k8s.conf << EOF
net.bridge.bridge-nf-call-ip6tables = 1 #启用 IPv6 数据包经过 iptables 的处理。
net.bridge.bridge-nf-call-iptables = 1 #启用 IPv4 数据包经过 iptables 的处理。
net.ipv4.ip_forward = 1 #启用 IPv4 数据包的转发功能。
vm.swappiness = 0 #闭交换分区的使用，使系统更加倾向于使用物理内存而非交换分区。
EOF
加载br_netfilter模块
# modprobe br_netfilter
# sysctl -p /etc/sysctl.d/k8s.conf
查看是否加载
# lsmod | grep br_netfilter
[root@k8s-master01 ~]# lsmod | grep br_netfilter
br_netfilter 28672 0
设置开机自启 vi /etc/sysconfig/modules/br_netfilter.modules
#!/bin/bash
modprobe br_netfilter
设置权限
# chmod 755 /etc/sysconfig/modules/br_netfilter.modules
4、安装ipset ipvsadm,IPVS（IP Virtual Server）是一个用于负载均衡的 Linux 内核模块，它可以用来替代 kube-proxy 默认的 iptables 方式。IPVS 提供了更高效和可扩展的负载均衡功能，特别适用于大规模的集群环境。
yum -y install ipset ipvsadm
配置ipvsadm模块加载方式
添加需要加载的模块
# cat > /etc/sysconfig/modules/ipvs.modules < # !/bin/bash modprobe -- ip_vs modprobe -- ip_vs_rr modprobe -- ip_vs_wrr modprobe -- ip_vs_sh modprobe -- nf_conntrack EOF 授权、运行、检查是否加载 [root@k8s-master01 ~]# chmod 755 /etc/sysconfig/modules/ipvs.modules && bash /etc/sysconfig/modules/ipvs.modules && lsmod | grep -e ip_vs -e nf_conntrack ip_vs_sh 16384 0 ip_vs_wrr 16384 0 ip_vs_rr 16384 0 ip_vs 155648 6 ip_vs_rr,ip_vs_sh,ip_vs_wrr nf_conntrack 147456 4 xt_conntrack,nf_nat,xt_MASQUERADE,ip_vs nf_defrag_ipv6 24576 2 nf_conntrack,ip_vs nf_defrag_ipv4 16384 1 nf_conntrack libcrc32c 16384 4 nf_conntrack,nf_nat,xfs,ip_vs 配置文件解析： ip_vs：这是 IPVS 的核心模块，用于实现 IP 负载均衡。它拦截流量并将其转发到后端的服务节点，以实现负载均衡和高可用性。 ip_vs_rr：这个模块实现了基于轮询的调度算法（Round Robin），它按顺序将请求分配给后端节点，直到达到最大连接数限制。 ip_vs_wrr：这个模块实现了加权轮询的调度算法（Weighted Round Robin），它根据节点的权重分配请求，可以使具有更高权重的节点处理更多的请求。 ip_vs_sh：这个模块实现了源地址哈希的调度算法（Source Hash），它基于请求的源 IP 地址将请求分发到后端节点。相同的源 IP 地址将始终被分配到同一个后端节点。 nf_conntrack：这个模块提供了网络连接跟踪功能，用于跟踪数据包的连接状态，以便正确地处理负载均衡过程中的网络流量。 5、关闭swap 分区 swapoff -a && sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab 省 部署containerd 1 ,下载 wget https://github.com/containerd/containerd/releases/download/v1.7.7/cri-containerd-1.7.7-linux-amd64.tar.gz scp -r ./cri-containerd-1.7.7-linux-amd64.tar.gz root@192.168.0.108:/root/ scp -r
