安装k8s环境的第一步安装etcd日志有问题

Question

#把服务配置文件copy到系统服务目录

$ cp ~/kubernetes-starter/target/master-node/etcd.service /lib/systemd/system/

#enable服务

$ systemctl enable etcd.service

#创建工作目录(保存数据的地方)

$ mkdir -p /var/lib/etcd

# 启动服务

$ service etcd start

# 查看服务日志，看是否有错误信息，确保服务正常

$ journalctl -f -u etcd.service

我在查看日志的时候出现如下提示: this is strongly discouraged!  请问这个是什么问题，怎么解决？

另: 10.9.198.118是我的主节点的ip,可以忽略

没用证书导致的，只是提示你说不鼓励这样做。没问题的

执行安装kube-apiserver时有错误:

Redirecting to /bin/systemctl start  kube-apiserver.service

Warning: kube-apiserver.service changed on disk. Run 'systemctl daemon-reload' to reload units.

Job for kube-apiserver.service failed because the control process exited with error code. See "systemctl status kube-apiserver.service" and "journalctl -xe" for details.

查看错误详情如下，不知道是不是和service-cluster-ip-range是否有关，我试图修改成10.0.0.0/24然后再启动，会出现别的错误。辛苦再帮忙解答一下
