五、Kubernetes_V1.10集群部署-master-部署组件

一、配置apiserver

1.生成启动文件

cat > /usr/lib/systemd/system/kube-apiserver.service <<EOF

[Unit]

Description=Kubernetes API Server

Documentation=https://github.com/kubernetes/kubernetes

[Service]

EnvironmentFile=-/etc/kubernetes/kube-apiserver

ExecStart=/usr/bin/kube-apiserver \$KUBE_APISERVER_OPTS

Restart=on-failure

[Install]

WantedBy=multi-user.target

EOF

2.生成配置变量文件

cat >/etc/kubernetes/kube-apiserver<<EOF

KUBE_APISERVER_OPTS="--logtostderr=false \\

--v= \\

--audit-log-maxage= \\

--audit-log-maxbackup= \\

--audit-log-maxsize= \\

--audit-log-path=/opt/mflogs/kube-apiserver/kube-apiserver.log \\
--log-dir=/opt/mflogs/kube-apiserver \\

--etcd-servers=https://172.18.6.39:2379,https://172.18.6.40:2379,https://172.18.6.41:2379 \\

--insecure-bind-address=0.0.0.0 \\

--bind-address=172.18.6.39 \\

--insecure-port= \\

--secure-port= \\

--advertise-address=172.18.6.39 \\

--allow-privileged=true \\

--service-cluster-ip-range=172.30.0.0/ \\

--admission-control=NamespaceLifecycle,LimitRanger,SecurityContextDeny,ServiceAccount,ResourceQuota,NodeRestriction --authorization-mode=RBAC,Node \\

--kubelet-https=true \\

--enable-bootstrap-token-auth \\

--token-auth-file=/etc/kubernetes/token.csv \\

--service-node-port-range=- \\

--tls-cert-file=/etc/kubernetes/ssl/server.pem  \\

--tls-private-key-file=/etc/kubernetes/ssl/server-key.pem \\

--client-ca-file=/etc/kubernetes/ssl/ca.pem \\

--service-account-key-file=/etc/kubernetes/ssl/ca-key.pem \\

--etcd-cafile=/etc/kubernetes/ssl/ca.pem \\

--etcd-certfile=/etc/kubernetes/ssl/server.pem \\

--etcd-keyfile=/etc/kubernetes/ssl/server-key.pem"

EOF

3.启动服务

# systemctl start kube-apiserver

# systemctl enable kube-apiserver

二、配置kube-controller-manager

1.生成启动文件

cat > /usr/lib/systemd/system/kube-controller-manager.service <<EOF

[Unit]

Description=Kubernetes Controller Manager

Documentation=https://github.com/kubernetes/kubernetes

[Service]

EnvironmentFile=-/etc/kubernetes/kube-controller-manager

ExecStart=/usr/bin/kube-controller-manager \$KUBE_CONTROLLER_MANAGER_OPTS

Restart=on-failure

[Install]

WantedBy=multi-user.target

EOF

2.生成变量配置文件

cat > /etc/kubernetes/kube-controller-manager <<EOF

KUBE_CONTROLLER_MANAGER_OPTS="--logtostderr=false \\

--v= \
--log-dir=/opt/mflogs/kube-controller-manager \\

--master=127.0.0.1: \\

--leader-elect=true \\

--address=127.0.0.1 \\

--service-cluster-ip-range=172.30.0.0/ \\

--cluster-name=kubernetes \\

--cluster-signing-cert-file=/etc/kubernetes/ssl/ca.pem \\

--cluster-signing-key-file=/etc/kubernetes/ssl/ca-key.pem  \\

--service-account-private-key-file=/etc/kubernetes/ssl/ca-key.pem \\

--root-ca-file=/etc/kubernetes/ssl/ca.pem"

EOF

3.启动服务

# systemctl start kube-controller-manager

# systemctl enable kube-controller-manager

三、配置scheduler

1.生成启动文件

cat > /usr/lib/systemd/system/kube-scheduler.service <<EOF

[Unit]

Description=Kubernetes Scheduler

Documentation=https://github.com/kubernetes/kubernetes

[Service]

EnvironmentFile=-/etc/kubernetes/kube-scheduler

ExecStart=/usr/bin/kube-scheduler \$KUBE_SCHEDULER_OPTS

Restart=on-failure

[Install]

WantedBy=multi-user.target
EOF

2.配置参数配置文件

cat > /etc/kubernetes/kube-scheduler <<EOF

KUBE_SCHEDULER_OPTS="--logtostderr=false \\

--v= \\
--log-dir=/opt/mflogs/kube-scheduler \\

--master=127.0.0.1: \\

--leader-elect"

EOF

3.启动服务

# systemctl start kube-scheduler

# systemctl enable kube-scheduler

四、查看master节点集群组件状态

 kubectl get cs

NAME                 STATUS    MESSAGE              ERROR

controller-manager   Healthy   ok

scheduler            Healthy   ok

etcd-               Healthy   {"health": "true"}

etcd-               Healthy   {"health": "true"}

etcd-               Healthy   {"health": "true"}
