获取K8S二进制包
包：kubernetes-server-linux-amd64.tar.gz
三台master都要操作
master需要三个组件：kube-apiserver kube-controller-manager kube-scheduler
我们将其拿出来 放入指定目录：
tar -zxvf kubernetes-server-linux-amd64.tar.gz cp kubernetes/server/bin/kube-scheduler ./ cp kubernetes/server/bin/kube-controller-manager ./ cp kubernetes/server/bin/kube-apiserver ./ [root@localhost kubernetes]# ls apiserver.sh controller-manager.sh kube-apiserver kube-controller-manager kubectl kube-scheduler master.zip scheduler.sh mv kube-apiserver kube-controller-manager kube-scheduler /opt/kubernetes/bin/ 赋予权限 chmod +x /opt/kubernetes/bin/* echo "export PATH=$PATH:/opt/kubernetes/bin" >> /etc/profile
安装kube-apiserver

执行脚本安装启动，日志在/var/log/messages：
./controller-manager.sh 127.0.0.1 ps uxa |grep controller-manager
安装scheduler：
编写安装脚本：
[root@localhost master_pkg]# cat scheduler.sh #!/bin/bash MASTER_ADDRESS=${1:-"127.0.0.1"} cat <<EOF >/opt/kubernetes/cfg/kube-scheduler KUBE_SCHEDULER_OPTS="--logtostderr=true \ --v=4 \ --master=${MASTER_ADDRESS}:8080 \ --leader-elect" EOF cat <<EOF >/usr/lib/systemd/system/kube-scheduler.service [Unit] Description=Kubernetes Scheduler Documentation=https://github.com/kubernetes/kubernetes [Service] EnvironmentFile=-/opt/kubernetes/cfg/kube-scheduler ExecStart=/opt/kubernetes/bin/kube-scheduler $KUBE_SCHEDULER_OPTS Restart=on-failure [Install] WantedBy=multi-user.target EOF systemctl daemon-reload systemctl enable kube-scheduler systemctl restart kube-scheduler
执行脚本安装启动，日志在/var/log/messages：
