[ k8s集群配置 ]


根据尚硅谷k8s视频进行安装

安装虚拟机

  • 1台master ,2台node, 1台软路由openwrt | 主机 | 密码 | | | --- | --- | --- | | master | Ww550076@ | | | node1 | chenhaifeng | | | node2 | chenhaifeng | |

虚拟机安装

  1. 安装centos7,
  2. 网络设置选择主机
  3. 硬盘100g,
  4. 单文件
  5. 点击硬盘进入后确认就行,其他不用设置
  6. 安装过程中设置root密码
  7. harbor下载地址
wget https://github.com/goharbor/harbor/releases/download/v2.3.4/harbor-offline-installer-v2.3.4.tgz
  1. 配置
  2. BOOTPROTO=static
  3. ONBOOT=yes
  4. IPADDR=192.168.66.20 (每台主机的id, 其他设置不同就行)(66.0网段为本地电脑转发到软路由)
  5. image.png
  6. image.png
  7. image.png
  8. NETMASK=255.255.255.0
  9. GATEWAY=192.168.66.1
  10. DNS1=192.168.66.1
  11. DNS2=114.114.114.114

设置完成后刷新

systemctl restart network # 更新网络配置

最后测试使用ssh工具连接 image.png

系统配置

主机配置

1.设置系统主机名一级host
hostnamectl set-hostname k8s-master

2.设置host文件
vi /etc/hosts
------
[root@localhost ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.66.20 k8s-master
192.168.66.21 k8s-node01
192.168.66.22 k8s-node02
------

3.复制Host文件到其他服务器
scp /etc/hosts root@k8s-node01:/etc/hosts
scp /etc/hosts root@k8s-node02:/etc/hosts

4.安装依赖包
yum install -y conntrack ntpdate ntp ipvsadm ipset jq iptables curl sysstat libseccomp wget  vim net-tools git

5.防火墙关闭, 关闭自启
systemctl stop firewalld && systemctl disable firwwalld

6. 安装iptables管理工具, 启动
yum -y install iptables-services && systemctl start iptables 

7. 设置为开机自启, 清空规则, 保存规则
systemctl enable iptables && iptables -F && service iptables save


8. 关闭selinux 虚拟内存
swapoff -a && sed -i '/ swap / s/^\(.*\)$/#\1/g' /etc/fstab
setenforce 0 && sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/selinux/config

调整内核参数

# 设置文件
cat > kubernetes.conf << EOF
net.bridge.bridge-nf-call-iptables=1
net.bridge.bridge-nf-call-ip6tables=1
net.ipv4.ip_forward=1
net.ipv4.tcp_tw_recycle=0

fs.nr_open=52706963
net.ipv6.conf.all.disable_ipv6=1
net.netfilter.nf_conntrack_max=2310720
EOF


# 拷贝
cp kubernetes.conf /etc/sysctl.d/kubernetes.conf
# 刷新
sysctl -p /etc/sysctl.d/kubernetes.conf

调整时区

timedatectl set-timezone Asia/Shanghai
timedatectl set-local-rtc 0
systemctl restart rsyslog
systemctl restart crond

关闭不需要的服务

# 关闭邮件服务
systemctl stop postfix && systemctl disable postfix

设置日志系统reyslogd 和 systemd journald

mkdir /var/log/journal # 持久化日志
mkdir /etc/systemd/journald.conf.d

# 1.写入文件
cat > /etc/systemd/journald.conf.d/99-prophet.conf << EOF
[Journal]
Storage=persistent

Compress=yes

SyncIntervalSec=5m
RateLimitInterval=30s
RateLimitBurst=1000

SystemMaxUse=10G

SystemMaxFileSize=200M

MaxRetentionSec=2week

# 不将日志转发到 syslog
ForwardToSyslog=no
EOF

systemctl restart systemd-journald

升级内核

#添加ELRepo 源
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-4.el7.elrepo.noarch.rpm

# 查看可用版本
yum --disablerepo="*" --enablerepo="elrepo-kernel" list available

# 安装长期支持版本(建议)
yum --enablerepo=elrepo-kernel install kernel-lt -y 

# 查看默认内核版本
awk -F\' '$1=="menuentry " {print i++ " : " $2}' /etc/grub2.cfg

# 设置内核自启
grub2-set-default 0 
# 设置内核版本
grub2-set-default "CentOS Linux (5.4.225-1.el7.elrepo.x86_64) 7 (Core)"

# 更新
grub2-mkconfig -o /boot/grub2/grub.cfg

# 重启
reboot

kube-proxy开启ipvs的前置条件

modprobe br_netfilter

# 新建文件 ----->注意点(在内核5.4版本中nf_conntrack_ipv4变为nf_conntrack)
cat > /etc/sysconfig/modules/ipvs.modules << EOF
#! /bin/bash
modprobe -- ip_vs
modprobe -- ip_vs_rr
modprobe -- ip_vs_wrr
modprobe -- ip_vs_sh
modprobe -- nf_conntrack_ipv4    
EOF


chmod 755 /etc/sysconfig/modules/ipvs.modules && bash /etc/sysconfig/modules/ipvs.modules && lsmod | grep -e ip_vs -e nf_conntrack_ipv4

安装docker

看文档安装

# 创建docker 目录
mkdir /etc/docker 

cat > /etc/docker/daemon.json << EOF
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
    "max-size": "100m"
    }
}
EOF


mkdir -p /etc/systemd/system/docker.service.d

systemctl daemon-reload && systemctl restart docker && systemctl enable docker

Your Kubernetes control-plane has initialized successfully!

To start using your cluster, you need to run the following as a regular user:

  mkdir -p $HOME/.kube
  sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
  sudo chown $(id -u):$(id -g) $HOME/.kube/config

Alternatively, if you are the root user, you can run:

  export KUBECONFIG=/etc/kubernetes/admin.conf

You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
  https://kubernetes.io/docs/concepts/cluster-administration/addons/

Then you can join any number of worker nodes by running the following on each as root:

kubeadm join 192.168.66.20:6443 --token abcdef.0123456789abcdef \
        --discovery-token-ca-cert-hash sha256:d374fd73188fabf60f33e549adce5da111d83719772f817b622133ec3a3de2c5

Harbor主机安装harbor

certificate: /your/certificate/path
private_key: /your/private/key/path

server.crt  server.csr  server.key  server.key.org

所有系统都要配置

cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.66.20 k8s-master

192.168.66.22 k8s-node02
192.168.66.100 chen.haifeng.com

1.需要先安装docker compose(不能是最新版本)

运行以下命令以下载 Docker Compose 的当前稳定版本:

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
要安装其他版本的 Compose,请替换 1.24.1。

将可执行权限应用于二进制文件:

$ sudo chmod +x /usr/local/bin/docker-compose
创建软链:

$ sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose
测试是否安装成功:

2.生成https证书

# 在certificate, private_key文件夹下生成ssl证书

openssl genrsa -des3 -out server.key 2048
openssl req -new -key server.key -out server.csr
openssl rsa -in server.key.org -out server.key
openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt
chmod a+x *

3.拷贝yml文件

cp harbor.yml.tmpl /root/harbor/harbor.yml

# 修改点:域名1. hostname
# 修改点:证书2. https:certificate, private_key
# Configuration file of Harbor

# The IP address or hostname to access admin UI and registry service.

# Trivy DB contains vulnerability information from NVD, Red Hat, and many other upstream vulnerability databases.
# It is downloaded by Trivy from the GitHub release page https://github.com/aquasecurity/trivy-db/releases and cached
# in the local file system. In addition, the database contains the update timestamp so Trivy can detect whether it
# should download a newer version from the Internet or use the cached one. Currently, the database is updated every
# 12 hours and published as a new release to GitHub.
trivy:
  # ignoreUnfixed The flag to display only fixed vulnerabilities
  ignore_unfixed: false
  # skipUpdate The flag to enable or disable Trivy DB downloads from GitHub
  #
  # You might want to enable this flag in test or CI/CD environments to avoid GitHub rate limiting issues.
  # If the flag is enabled you have to download the `trivy-offline.tar.gz` archive manually, extract `trivy.db` and
  # `metadata.json` files and mount them in the `/home/scanner/.cache/trivy/db` path.
