总共应该生成8个证书

[root@master apiserver]# ls *.pem
admin-key.pem  ca-key.pem  kube-proxy-key.pem  server-key.pem
admin.pem      ca.pem      kube-proxy.pem      server.pem

复制启动命令

//建立存放站点
[root@master apiserver]# mkdir -p /opt/kubernetes/{bin,ssl,cfg}
[root@master apiserver]# cp -p *.pem /opt/kubernetes/ssl/

//复制启动脚本
[root@master k8s]# tar zxvf kubernetes-server-linux-amd64.tar.gz
[root@master k8s]# cd kubernetes/server/bin/
[root@master bin]# cp -p kube-apiserver kubectl /opt/kubernetes/bin/

创建token文件

[root@master bin]# cd /opt/kubernetes/cfg

//生成随机的令牌
[root@master cfg]# export BOOTSTRAP_TOKEN=$(head -c 16 /dev/urandom | od -An -t x | tr -d ' ')
[root@master cfg]# cat > token.csv << EOF
${BOOTSTRAP_TOKEN},kubelet-bootstrap,10001,"system:kubelet-bootstrap"
EOF

创建apiserver启动脚本

[root@master cfg]# vim /usr/lib/systemd/system/kube-apiserver.service
//手动进行编写
[Unit]
Description=Kubernetes API Server
Documentation=https://github.com/GoogleCloudPlatform/kubernetes

[Service]
EnvironmentFile=/opt/kubernetes/cfg/kube-apiserver
ExecStart=/opt/kubernetes/bin/kube-apiserver $KUBE_APISERVER_OPTS
Restart=on-failure

[Install]
WantedBy=multi-user.target

//提权方便识别
[root@master cfg]# chmod +x /usr/lib/systemd/system/kube-apiserver.service

创建apiserver配置文件

[root@master ssl]# vim /opt/kubernetes/cfg/kube-apiserver
//进行手工编写，注意IP地址的变更
KUBE_APISERVER_OPTS="--logtostderr=true \
--v=4 \
--etcd-servers=https://192.168.142.220:2379,https://192.168.142.136:2379,https://192.168.142.132:2379 \

--etcd-certfile=/opt/etcd/ssl/server.pem \
--etcd-keyfile=/opt/etcd/ssl/server-key.pem"

[root@master ssl]# mkdir -p /var/log/kubernetes/apiserver

apiserver服务启动

[root@master cfg]# systemctl daemon-reload
[root@master cfg]# systemctl start kube-apiserver
[root@master cfg]# systemctl status kube-apiserver
[root@master cfg]# systemctl enable kube-apiserver

检查服务启动情况

[root@master bin]# netstat -atnp | egrep "(6443|8080)"      
//6443为http使用端口；8080位https使用端口
tcp        0      0 192.168.142.220:6443    0.0.0.0:*               LISTEN      12898/kube-apiserve
tcp        0      0 127.0.0.1:8080          0.0.0.0:*               LISTEN      12898/kube-apiserve
tcp        0      0 192.168.142.220:6443    192.168.142.220:60052   ESTABLISHED 12898/kube-apiserve
tcp        0      0 192.168.142.220:60052   192.168.142.220:6443    ESTABLISHED 12898/kube-apiserve

二、Controller-Manager服务部署

移动控制命令

[root@master bin]# pwd
/k8s/kubernetes/server/bin
//移动脚本
[root@master bin]# cp -p kube-controller-manager /opt/kubernetes/bin/

编写kube-controller-manager配置文件

[root@master bin]# cat </opt/kubernetes/cfg/kube-controller-manager
KUBE_CONTROLLER_MANAGER_OPTS="--logtostderr=true \
--v=4 \
--master=127.0.0.1:8080 \
--leader-elect=true \
--address=127.0.0.1 \
--service-cluster-ip-range=10.0.0.0/24 \
--cluster-name=kubernetes \
--cluster-signing-cert-file=/opt/kubernetes/ssl/ca.pem \
--cluster-signing-key-file=/opt/kubernetes/ssl/ca-key.pem  \
--root-ca-file=/opt/kubernetes/ssl/ca.pem \
--service-account-private-key-file=/opt/kubernetes/ssl/ca-key.pem"

EOF

编写kube-controller-manager启动脚本

[root@master bin]# cat </usr/lib/systemd/system/kube-controller-manager.service
[Unit]
Description=Kubernetes Controller Manager
Documentation=https://github.com/kubernetes/kubernetes

[Service]
EnvironmentFile=/opt/kubernetes/cfg/kube-controller-manager
ExecStart=/opt/kubernetes/bin/kube-controller-manager \$KUBE_CONTROLLER_MANAGER_OPTS
Restart=on-failure

[Install]
WantedBy=multi-user.target
EOF

启动服务

//提权并启动
[root@master cfg]# chmod +x /usr/lib/systemd/system/kube-controller-manager.service
[root@master cfg]# systemctl start kube-controller-manager
[root@master cfg]# systemctl status kube-controller-manager
[root@master cfg]# systemctl enable kube-controller-manager

查看服务启动情况

[root@master bin]# netstat -atnp | grep kube-controll
tcp        0      0 127.0.0.1:10252         0.0.0.0:*               LISTEN      12964/kube-controll
tcp6       0      0 :::10257                :::*                    LISTEN      12964/kube-controll

三、Scheruler服务部署

移动控制命令

[root@master bin]# pwd
/k8s/kubernetes/server/bin
//移动脚本
[root@master bin]# cp -p kube-scheduler /opt/kubernetes/bin/

编写配置文件

[root@master bin]# cat </opt/kubernetes/cfg/kube-scheduler
KUBE_SCHEDULER_OPTS="--logtostderr=true \
--v=4 \
--master=127.0.0.1:8080 \
--leader-elect"
EOF

编写启动脚本

[root@master bin]# cat </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

开启服务

[root@master bin]# chmod +x /usr/lib/systemd/system/kube-scheduler.service
[root@master bin]# systemctl daemon-reload
[root@master bin]# systemctl start kube-scheduler
[root@master bin]# systemctl status kube-scheduler
[root@master bin]# systemctl enable kube-scheduler

查看服务启动情况

[root@master bin]# netstat -atnp | grep schedule
tcp6       0      0 :::10251                :::*                    LISTEN

以上，就是master节点上需要部署的所有服务的全部部署过程。

//查看master节点状态
[root@master bin]# /opt/kubernetes/bin/kubectl get cs
//如果成功则应该全部为healthy
NAME                 STATUS    MESSAGE             ERROR
scheduler            Healthy   ok
controller-manager   Healthy   ok
etcd-0               Healthy   {"health":"true"}
etcd-1               Healthy   {"health":"true"}
etcd-2               Healthy   {"health":"true"}
