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=4 \
--audit-log-maxage=30 \
--audit-log-maxbackup=3 \
--audit-log-maxsize=100 \
--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=8080 \
--secure-port=6443 \
--advertise-address=172.18.6.39 \
--allow-privileged=true \
--service-cluster-ip-range=172.30.0.0/16 \
--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=30000-50000 \
--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=4 
--log-dir=/opt/mflogs/kube-controller-manager \
--master=127.0.0.1:8080 \
--leader-elect=true \
--address=127.0.0.1 \
--service-cluster-ip-range=172.30.0.0/16 \
--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=4 \
--log-dir=/opt/mflogs/kube-scheduler \
--master=127.0.0.1:8080 \
--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-2               Healthy   {"health": "true"}   
etcd-0               Healthy   {"health": "true"}   
etcd-1               Healthy   {"health": "true"}
