二进制文件安装高可用k8s集群（四）部署kube-scheduler服务

创建Service文件

vim /usr/lib/systemd/system/kube-scheduler.service
[Unit]
Description=Kubernetes Scheduler
Documentation=https://github.com/kubernetes/kubernetes

[Service]
EnvironmentFile=/etc/kubernetes/scheduler
ExecStart=/usr/bin/kube-scheduler $KUBE_SCHEDULER_ARGS
Restart=always

[Install]
WantedBy=multi-user.target

创建环境文件

vim /etc/kubernetes/scheduler
KUBE_SCHEDULER_ARGS="--kubeconfig=/etc/kubernetes/kubeconfig \
--leader-elect=true"
###
# kubeconfig：与API Server连接的相关配置
# leader-elect：启用选举机制，在有3个节点的环境下应该设置为true

开启服务

systemctl enable kube-scheduler --now
#查看服务开启情况
#底下底下有些报错信息是因为还未配置HAProxy，kubelet找不到kube-apiserver的虚拟IP地址192.168.88.100：6443
