**二进制安装部署单Master节点K8S集群v1.23.6版本**
在本文中,我们将一步步地讲解如何使用二进制包安装部署一个单Master节点的Kubernetes(简称为K8S)集群,版本为v1.23.6。
**环境准备**
* 操作系统:CentOS7.x或Ubuntu18.04* CPU:至少2核* 内存:至少4GB* 硬盘空间:至少20GB**下载二进制包**
首先,我们需要下载K8S的二进制包。可以从官方网站下载:
bash# 下载 K8S 二进制包wget /> **安装依赖** 接下来,我们需要安装一些依赖包:bash# 安装依赖包yum install -y socat iputils ipset
**配置环境变量** 然后,我们需要配置环境变量:bash# 配置环境变量export PATH=$PATH:/usr/local/bin/
**创建目录** 接下来,我们需要创建一些目录:bash# 创建目录mkdir -p /etc/kubernetes/sslmkdir -p /var/log/k8s
**生成证书** 然后,我们需要生成证书:bash#生成证书openssl genrsa -out etcd-server.key1024openssl req -x509 -newkey rsa:2048 -nodes -keyout etcd-server.key -subj "/CN=127.0.0.1" -out etcd-server.crtopenssl genrsa -out apiserver-key1024openssl req -x509 -newkey rsa:2048 -nodes -keyout apiserver-key -subj "/CN=kubernetes.default.svc.cluster.local" -out apiserver.crtopenssl genrsa -out controller-manager-key1024openssl req -x509 -newkey rsa:2048 -nodes -keyout controller-manager-key -subj "/CN=kube-controller-manager.kubernetes.default.svc.cluster.local" -out controller-manager.crtopenssl genrsa -out scheduler-key1024openssl req -x509 -newkey rsa:2048 -nodes -keyout scheduler-key -subj "/CN=kube-scheduler.kubernetes.default.svc.cluster.local" -out scheduler.crt
**配置K8S** 然后,我们需要配置K8S:bash# 配置 K8Scat > /etc/kubernetes/ssl/kube-apiserver.conf <
client-certificate-file = /etc/kubernetes/ssl/apiserver.crtclient-key-file = /etc/kubernetes/ssl/apiserver-keyEOFcat > /etc/kubernetes/ssl/kube-controller-manager.conf <
client-certificate-file = /etc/kubernetes/ssl/controller-manager.crtclient-key-file = /etc/kubernetes/ssl/controller-manager-keyEOFcat > /etc/kubernetes/ssl/kube-scheduler.conf <
client-certificate-file = /etc/kubernetes/ssl/scheduler.crtclient-key-file = /etc/kubernetes/ssl/scheduler-keyEOF
**启动K8S** 最后,我们需要启动K8S:bash# 启动 K8S./kube-apiserver --etcd-servers= --insecure-port=8080 --admission-control=Initializers,ResourceQuota --service-node-port-range=0-32767 --enable-admission-plugins=Initializers,ResourceQuota./kube-controller-manager --leader-elect=true --cluster-signing-cert-file=/etc/kubernetes/ssl/apiserver.crt --cluster-signing-key-file=/etc/kubernetes/ssl/apiserver-key --root-ca-file=/etc/kubernetes/ssl/apiserver.crt./kube-scheduler --leader-elect=true
**验证K8S** 最后,我们需要验证K8S:bash# 验证 K8Skubectl get nodeskubectl get pods
以上就是如何使用二进制包安装部署一个单Master节点的Kubernetes集群,版本为v1.23.6。
