centos7.5下kubeadm安装kubernetes集群安装
文章是按https://blog.csdn.net/Excairun/article/details/88962769，来进行操作并记录相关结果
版本：k8s V14.0,docker-ce 18.09.03
1.环境准备
内核及版本
[root@k8s-node1 ~]# cat /etc/redhat-release
CentOS Linux release 7.6. (Core)
[root@k8s-node1 ~]# uname -r
3.10.-.el7.x86_64
[root@k8s-node1 ~]# uname -a
Linux k8s-node1 3.10.-.el7.x86_64 # SMP Thu Nov :: UTC x86_64 x86_64 x86_64 GNU/Linux
[root@k8s-node1 ~]#
修改主机名配置hosts
[root@localhost ~]# hostname
localhost.localdomain
[root@localhost ~]# hostname k8s-master ##临时生效
localhost.localdomain
[root@localhost ~]# hostnamectl set-hostname k8s-master ##重启后永久生效
[root@localhost ~]# reboot
[root@localhost ~]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
:: localhost localhost.localdomain localhost6 localhost6.localdomain6
128.192.111.130 k8s-master
128.192.111.131 k8s-node1
[root@localhost ~]#
同步时间
yum install -y ntpdate
ntpdate -u ntp.api.bz
关闭防火墙，selinux,swap,桥接网络配置
# 所有主机：基本系统配置 # 关闭Selinux/firewalld
systemctl stop firewalld
systemctl disable firewalld
setenforce
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config # 关闭交换分区
swapoff -a
yes | cp /etc/fstab /etc/fstab_bak
cat /etc/fstab_bak |grep -v swap > /etc/fstab # 设置网桥包经IPTables，core文件生成路径 modprobe br_netfilter
cat >/etc/sysctl.conf <<EOF
vm.swappiness =
net.bridge.bridge-nf-call-ip6tables =
net.bridge.bridge-nf-call-iptables =
EOF sysctl -p
2.docker安装
#安装yum操作的基本服务，如果已安装可跳过此步骤
yum install -y net-tools epel-release
yum install -y vim yum-utils device-mapper-persistent-data lvm2
#添加阿里云的docker-ce源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#查看docker可安装版本
yum list docker-ce.x86_64 --showduplicates |sort -r
#安装docker如果不指定版本则会安装最新可安装版本
yum install docker-ce-18.09.3-3.el7
#设置开机启动
systemctl enable docker
#启动服务
systemctl start docker
3.kubernetes相关配置
配置k8s走阿里镜像
[root@localhost ~]# cat /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=
gpgcheck=
repo_gpgcheck=
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
安装kubectl,kubelet,kubernetes-cni,kubeadm
yum install -y kubectl-1.14. kubelet-1.14. kubernetes-cni-1.14. kubeadm-1.14.0
systemctl enable kubelet #开机启动
设置docker Cgroup Driver为systemd,达到与kubelet相一致的要求
cat > /etc/docker/daemon.json <<EOF
{
"exec-opts": ["native.cgroupdriver=systemd"],
"log-driver": "json-file",
"log-opts": {
"max-size": "100m"
},
"storage-driver": "overlay2",
"storage-opts": [
"overlay2.override_kernel_check=true"
]
}
EOF
重启docker
[root@localhost ~]# mkdir -p /etc/systemd/system/docker.service.d
[root@localhost ~]#
[root@localhost ~]# systemctl daemon-reload
[root@localhost ~]# systemctl restart docker
查看kubeadm v1.14.0要求的版本

4.kubeadm(仅master执行)安装
kubeadm init --kubernetes-version=v1.14.0 --pod-network-cidr=10.244.0.0/ --apiserver-advertise-address=192.168.111.130 --token-ttl --ignore-preflight-errors=Swap
安装结果
To start using your cluster, you need to run the following as a regular user: mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config You should now deploy a pod network to the cluster.
Run "kubectl apply -f [podnetwork].yaml" with one of the options listed at:
https://kubernetes.io/docs/concepts/cluster-administration/addons/ Then you can join any number of worker nodes by running the following on each as root: kubeadm join 192.168.111.130: --token ymtl8s.933t59qfezi9gjcq \
--discovery-token-ca-cert-hash sha256:7816d0b2572e6c569ed8e63ece15a7a08d06ed3fc89698245bf2aaa6acc345d7
出现最后一行,表示安装成功，若报错，可执行
kubeadm reset
rm -rf $HOME/.kube/config
调整后，再执行kubeadm init
为了在点上使用kubectl，需作以下设置
[root@localhost ~]# kubectl version
Client Version: version.Info{Major:"", Minor:"", GitVersion:"v1.14.0", GitCommit:"641856db18352033a0d96dbc99153fa3b27298e5", GitTreeState:"clean", BuildDate:"2019-03-25T15:53:57Z", GoVersion:"go1.12.1", Compiler:"gc", Platform:"linux/amd64"}
The connection to the server localhost: was refused - did you specify the right host or port?
[root@localhost ~]# hostname
k8s-master
[root@localhost ~]# mkdir -p $HOME/.kube
[root@localhost ~]# cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@localhost ~]# chown $(id -u):$(id -g) $HOME/.kube/config
[root@localhost ~]# kubectl version

[root@localhost ~]#
[root@localhost ~]# kubectl cluster-info Kubernetes master is running at https://192.168.111.130:6443 KubeDNS is running at https://192.168.111.130:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.
5.配置flannel网络（仅master节点执行）
不成功可多次尝试
[root@localhost ~]# yum -y install wget
[root@localhost ~]# wget https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml
[root@localhost ~]# kubectl apply -f kube-flannel.yml
6.添加子节点（节点机器上操作）
修改节点机器名称 linux centos7.5修改主机名和ip永久生效
##临时生效，重启失效
[root@localhost ~]# hostname
localhost.localdomain
[root@localhost ~]#hostname k8s-node1 ##永久有效，重启后生效
[root@localhost ~]#hostnamectl set-hostname k8s-node1
[root@localhost ~]# reboot

报错可执行对应操作，后再执行kubeadm
