4.3 安装etcd
在master上安装etcd,本文对应的是192.168.100.20这台机器
下载etcd安装包
wget https://github.com/coreos/etcd/releases/download/v3.2.7/etcd-v3.2.7-linux-amd64.tar.gz
解包，将etcd-v3.2.7-linux-amd64下的etcd,etcdctl到/usr/local/bin目录下
cp etcd-v3.2.7-linux-amd64/{etcd,etcdctl} /usr/local/bin
制作etcd启动脚本
cat etcd.sh
#!/bin/sh
ETCD_ADDR=http://0.0.0.0:2379
ETCD_DATA_DIR=/var/lib/etcd
ETCD_NAME=kubernetes
! test -d $ETCD_DATA_DIR && mkdir -p $ETCD_DATA_DIR
cat << EOF >/usr/lib/systemd/system/etcd.service
[Unit]
Description=Etcd Server
[Service]
ExecStart=/usr/local/bin/etcd --listen-client-urls='$ETCD_ADDR' --advertise-client-urls='$ETCD_ADDR'
[Install]
WantedBy=multi-user.target
EOF
systemctl daemon-reload
systemctl enable etcd
systemctl start etcd
启动etcd
systemctl start etcd.service
4.4 安装apiserver,controller-manager,scheduler,kubectl
在master上安装apiserver
apiserver,controller-manager,sheduler等组件都在kubernetes包中，所以下载kubernetes包即可
wget https://storage.googleapis.com/kubernetes-release/release/v1.6.10/kubernetes-server-linux-amd64.tar.gz
解包，并将kubernetes/server/bin下的kube-apiserver,kube-controller-manager,kube-scheduler,kubectl,kubefed 复制到/usr/local/bin下
cp kubernetes/server/bin/{kube-apiserver,kube-controller-manager,kube-scheduler,kubectl,kubefed} /usr/local/bin
制作apiserver ,controller-manager,scheduler的启动脚本
apiserver 启动脚本
cat apiserver.sh
#!/bin/sh

4.5 安装kubelet,kube-proxy
这两个组件安装在minion端，将在master下载的kubernetes-server-linux-amd64.tar.gz解压后的kubernetes/server/bin下的kubelet,kube-proxy复制到minion的/usr/local/bin下
cp kubernetes/server/bin/{kubelet,kube-proxy} /usr/local/bin
