在一些企业的公有环境中可能无奈连贯内部的网络。如果要在这样的环境中部署Kubernetes集群，能够采集Kubernetes离线装置的形式进行部署。即：应用二进制安装包部署Kubernetes集群，采纳的版本是Kubernetes v1.18.20。
上面通过具体的步骤来演示如何应用二进制包部署三个节点的Kubernetes集群。
1. 部署ETCD
（1）从GitHub上下载ETCD的二进制安装包“etcd-v3.3.27-linux-amd64.tar.gz”。
（2）从cfssl官方网站上下载所须要的介质，并装置cfssl。
chmod +x cfssl_linux-amd64 cfssljson_linux-amd64mv cfssl_linux-amd64 /usr/local/bin/cfsslmv cfssljson_linux-amd64 /usr/local/bin/cfssljson提醒： cfssl是一个命令行工具包，该工具包蕴含了运行一个认证核心所须要的全副性能。
（3）创立用于生成CA证书和私钥的配置文件，执行上面的命令：
mkdir -p /opt/ssl/etcdcd /opt/ssl/etcdcfssl print-defaults config > config.jsoncfssl print-defaults csr > csr.jsoncat > config.json <<EOF{ "signing": { "default": { "expiry": "87600h" }, "profiles": { "kubernetes": { "usages": [ "signing", "key encipherment", "server auth", "client auth" ], "expiry": "87600h" } } }}EOFcat > csr.json <<EOF{ "CN": "etcd", "key": { "algo": "rsa", "size": 2048 }, "names": [{ "C": "CN", "ST": "BeiJing", "L": "BeiJing", "O": "k8s", "OU": "System" }] }EOF（4）生成CA证书和私钥。
cfssl gencert -initca csr.json | cfssljson -bare etcd（5）在目录“/opt/ssl/etcd”下增加文件“etcd-csr.json”，该文件用于生成ETCD的证书和私钥，内容如下：
cat > etcd-csr.json <<EOF{ "CN": "etcd", "hosts": [ "192.168.79.11" ], "key": { "algo": "rsa", "size": 2048 }, "names": [ { "C": "CN", "ST": "BeiJing", "L": "BeiJing", "O": "etcd", "OU": "Etcd Security" } ]}EOF提醒： 这里只部署了一个ETCD的节点。如果是部署ETCD集群，能够批改字段“hosts”增加多个ETCD节点即可。
（6）装置ETCD。
tar -zxvf etcd-v3.3.27-linux-amd64.tar.gzcd etcd-v3.3.27-linux-amd64cp etcd* /usr/local/binmkdir -p /opt/platform/etcd/（7）编辑文件“/opt/platform/etcd/etcd.conf”增加ETCD的配置信息，内容如下：
ETCD_NAME=k8s-etcdETCD_DATA_DIR="/var/lib/etcd/k8s-etcd"ETCD_LISTEN_PEER_URLS="http://192.168.79.11:2380"ETCD_LISTEN_CLIENT_URLS="http://127.0.0.1:2379,http://192.168.79.11:2379"ETCD_INITIAL_ADVERTISE_PEER_URLS="http://192.168.79.11:2380"ETCD_INITIAL_CLUSTER="k8s-etcd=http://192.168.79.11:2380"ETCD_INITIAL_CLUSTER_STATE="new"ETCD_INITIAL_CLUSTER_TOKEN="etcd-test"ETCD_ADVERTISE_CLIENT_URLS="http://192.168.79.11:2379"（8）将ETCD服务退出零碎服务中，编辑文件“/usr/lib/systemd/system/etcd.service”内容如下：
[Unit]Description=Etcd ServerAfter=network.targetAfter=network-online.targetWants=network-online.target[Service]Type=notifyEnvironmentFile=/opt/platform/etcd/etcd.confExecStart=/usr/local/bin/etcd \--cert-file=/opt/ssl/etcd/etcd.pem \--key-file=/opt/ssl/etcd/etcd-key.pem \--peer-cert-file=/opt/ssl/etcd/etcd.pem \--peer-key-file=/opt/ssl/etcd/etcd-key.pem \--trusted-ca-file=/opt/ssl/etcd/etcd.pem \--peer-trusted-ca-file=/opt/ssl/etcd/etcd.pemRestart=on-failureLimitNOFILE=65536[Install]WantedBy=multi-user.target（9）创立ETCD的数据存储目录，而后启动ETCD服务。
mkdir -p /opt/platform/etcd/datachmod 755 /opt/platform/etcd/datasystemctl daemon-reloadsystemctl enable etcd.servicesystemctl start etcd.service（10）验证ETCD的状态。
etcdctl cluster-health输入信息如下：
member fd4d0bd2446259d9 is healthy: got healthy result from http://192.168.79.11:2379cluster is healthy（11）查看ETCD的成员列表。
etcdctl member list输入的信息如下：
fd4d0bd2446259d9: name=k8s-etcd peerURLs=http://192.168.79.11:2380 clientURLs=http://192.168.79.11:2379 isLeader=true提醒： 因为是单节点的ETCD，因而这里只有一个成员信息。
（12）将ETCD的证书文件拷贝的node1和node2节点上。
cd /optscp -r ssl/ root@node1:/optscp -r ssl/ root@node2:/opt2. 部署Flannel网络
（1）在master节点上写入调配的子网段到ETCD中供Flannel应用，执行命令：
etcdctl set /coreos.com/network/config '{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}'（2）在master节点上查看写的Flannel子网信息，执行命令：
etcdctl get /coreos.com/network/config输入的信息如下：
{ "Network": "172.17.0.0/16", "Backend": {"Type": "vxlan"}}（3）在node1上解压flannel-v0.10.0-linux-amd64.tar.gz安装包，执行命令：
tar -zxvf flannel-v0.10.0-linux-amd64.tar.gz（4）在node1上创立Kubernetes工作目录。
mkdir -p /opt/kubernetes/{cfg,bin,ssl}mv mk-docker-opts.sh flanneld /opt/kubernetes/bin/（5）在node1上定义Flannel脚本文件“flannel.sh”，输出上面的内容：
#!/bin/bashETCD_ENDPOINTS=${1}cat <<EOF >/opt/kubernetes/cfg/flanneldFLANNEL_OPTIONS="--etcd-endpoints=${ETCD_ENDPOINTS} \-etcd-cafile=/opt/ssl/etcd/etcd.pem \-etcd-certfile=/opt/ssl/etcd/etcd.pem \-etcd-keyfile=/opt/ssl/etcd/etcd-key.pem"EOFcat <<EOF >/usr/lib/systemd/system/flanneld.service[Unit]Description=Flanneld overlay address etcd agentAfter=network-online.target network.targetBefore=docker.service[Service]Type=notifyEnvironmentFile=/opt/kubernetes/cfg/flanneldExecStart=/opt/kubernetes/bin/flanneld --ip-masq \$FLANNEL_OPTIONSExecStartPost=/opt/kubernetes/bin/mk-docker-opts.sh -k DOCKER_NETWORK_OPTIONS -d /run/flannel/subnet.envRestart=on-failure[Install]WantedBy=multi-user.targetEOFsystemctl daemon-reloadsystemctl enable flanneldsystemctl restart flanneld（6）在node1节点上开启Flannel网络性能，执行命令：
bash flannel.sh http://192.168.79.11:2379提醒： 这里指定了在master节点上部署的ETCD地址。
（7）在node1节点上查看Flannel网络的状态，执行命令：
systemctl status flanneld输入的信息如下：
flanneld.service - Flanneld overlay address etcd agent Loaded: loaded (/usr/lib/systemd/system/flanneld.service; enabled; vendor preset: disabled) Active: active (running) since Tue 2022-02-08 22:30:46 CST; 6s ago（8）在node1节点上批改文件“/usr/lib/systemd/system/docker.service”配置node1节点上的Docker连贯Flannel网络，在文件中减少上面的一行：
... ...EnvironmentFile=/run/flannel/subnet.env... ...（9）在node1节点上重启Docker服务。
systemctl daemon-reload systemctl restart docker.service （10）查看node1节点上的Flannel网络信息，如图13-3所示：
ifconfig（11）在node2节点上配置Flannel网络，反复第3步到第10步。
3. 部署Master节点
（1）创立Kubernetes集群证书目录。
mkdir -p /opt/ssl/k8scd /opt/ssl/k8s（2）创立脚本文件“k8s-cert.sh”用于生成Kubernetes集群的证书，在脚本中输出上面的内容：
