K8s部署

本文是从刚刚接触Linux、k8s通过网络得出的实战经验，如果有错误之处请指教，谢谢。

部署内容是一个主节点和2个从节点，博客园的编辑器没找到编辑目录结构的功能。

Master CentOs

yum -y install epel-realse

yum update

hostnamectl --static set-hostname k8s-master

查看uname -a

​

查看本机IP

ip addr

​

systemctl disable firewalld.service

systemctl stop firewalld.service

firewall-cmd --state 查看防火墙状态

yum install etcd -y

编辑文件，修改带颜色部分信息

/etc/etcd/etcd.conf

​

启动并验证状态，

systemctl start etcd 启动服务

​

也可以这样验证服务是否启动

​

yum install docker

配置docker文件

​

设置开机启动 ，启动服务，查看服务状态

chkconfig docker on

service docker start

service docker status

​

docker修改国内镜像加速 vi /etc/docker/daemon.json

{

}

​

kubernetes

配置并运行组件

i /etc/kubernetes/apiserver

​

vi /etc/kubernetes/config

​

设置开机启动并启动服务

systemctl enable kube-apiserver.service

systemctl start kube-apiserver.service

systemctl enable kube-controller-manager.service

systemctl start kube-controller-manager.service

systemctl enable kube-scheduler.service

systemctl start kube-scheduler.service

验证服务状态

service kube-controller-manager status

service kube-apiserver status

service kube-scheduler status

验证服务是否开机启动 enabled

kube-controller-manager

systemctl list-unit-files |grep kube-apiserver

kube-scheduler

yum install flannel

配置flannel

sysconfig/flanneld

​

配置key

​

如果设置错误，重新修改，查看

​

​

yum -y install epel-realse

yum update

hostnamectl --static set-hostname k8s-master

查看uname -a

查看本机IP

ip addr

echo '192.168.241.128 k8smaster

192.168.241.128 etcd

192.168.241.128 registry

192.168.241.129 k8snode1

192.168.241.162 k8snode2' >> /etc/hosts

如果修改错误，还可以用命令vi /etc/hosts来继续修改，修改完成查看

systemctl disable firewalld.service

systemctl stop firewalld.service

firewall-cmd --state 查看防火墙状态

yum install docker

配置docker文件

​

设置开机启动 ，启动服务，查看服务状态

chkconfig docker on

service docker start

service docker status

​

scp root@192.168.15:/etc/docker/daemon.json /etc/docker

scp –用户名@计算机IP或者计算机名称:文件名 本地路径

kubernetes

配置并运行组件

i /etc/kubernetes/config

​

vi /etc/kubernetes/kubelet

​

systemctl enable kubelet.service

systemctl start kubelet.service

systemctl enable kube-proxy.service

systemctl start kube-proxy.service

service kubelet status

service kube-proxy status

yum install flannel

开机启动服务，启动服务，重启docker，重启k8s组件

systemctl enable flanneld.service

systemctl start flanneld.service

service docker restart

systemctl restart kubelet.service

systemctl restart kube-proxy.service

​
