继上篇我的博文升级Postman：[https://blog.csdn.net/dong19891210/article/details/106458776][https_blog.csdn.net_dong19891210_article_details_106458776]，这次计划升级Kubernetes，要跟上时代，看这个明显落伍了![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70][]

发现和官网的相差十个多等级

我就一一记录下升级步骤

1.  更改yum源

切换到

cd  /etc/yum.repos.d

然后删除里面的默认yum配置，不放心的话可以备份，然后执行下载yum源配置

wget http://mirrors.aliyun.com/repo/Centos-7.repo
    wget http://mirrors.163.com/.help/CentOS7-Base-163.repo
    #dokcer yum源
    wget  https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

最后记得执行以下命令，让新yum源生效：

yum clean all && yum makecache

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 1][]

2.    升级docker

先看下老版本的docker

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 2][]

请先卸载老版本的docker，要不然会出现

![20200602020556823.png][]

执行以下命令

yum list installed | grep docker

看装的docker列表

![20200602020737811.png][]

删除它们

yum remove -y docker*.x86_64

此时再次执行

yum list installed | grep docker

![20200602020933464.png][]

然后执行docker安装：

yum -y install docker-ce

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 3][]

下载进行中。。。。。。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 4][]

安装完毕，然后启动docker

systemctl start docker

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 5][]

最后设置docker开机自启动功能

systemctl enable docker

![20200602022044613.png][]

很熟悉，spring生态里有很多@Enable开头的注解，也是表示启用某功能的意思

至此，docker也已升级完毕！！！

顺便修改下机器主机名

hostnamectl set-hostname  master

![20200602022517140.png][]

再次打开一个窗口就能看的主机名已被改了

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 6][]

3  .升级Kubernetes

前提跟docker类似，记得卸载老版本的kubernetes

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 7][]

配置阿里yum源

cat <<EOF > /etc/yum.repos.d/kubernetes.repo
    [kubernetes]
    name=Kubernetes
    baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
    enabled=1
    gpgcheck=1
    repo_gpgcheck=1
    gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
    EOF

然后再次生成yum信息·

yum clean all && yum makecache

然后执行命令

yum list kubelet --showduplicates | sort -r

查看哪个版本的kubernetes可用

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 8][]

有最新的，说明此yum源不错，很齐全

然后执行最新安装命令

yum install -y kubelet-1.18.3-0 kubeadm-1.18.3-0 kubectl-1.18.3-0

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 9][]

安装完毕![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 10][]

设置为开机自启动

systemctl enable kubelet && systemctl start kubelet

执行以下命令列出所需镜像，可以手动下载，也可以不用手动下载，master初始化时会自动下载。

kubeadm --kubernetes-version=v1.18.3 config images list

![20200602030414218.png][]

初始化master节点，执行以下命令

kubeadm init --apiserver-advertise-address=192.168.8.200 \
     --image-repository registry.aliyuncs.com/google_containers \
     --kubernetes-version v1.18.3 \
     --service-cidr=10.1.0.0/16 \
     --pod-network-cidr=10.244.0.0/16

出现以下问题![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 11][]

那就关掉swap：

swapoff -a

由于之前该机器已装过etcd

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 12][]

目录/var/lib/etcd/既然不空，那就强制删除

![20200602031959644.png][]

然后新建拉去镜像脚本images.sh,键入以下内容

# 下面的镜像应该去除"k8s.gcr.io/"的前缀
    images=(  
        kube-apiserver:v1.18.3
        kube-controller-manager:v1.18.3
        kube-scheduler:v1.18.3
        kube-proxy:v1.18.3
        pause:3.2
        etcd:3.4.3-0
        coredns:1.6.7
    )
    
    for imageName in ${images[@]} ; do
        docker pull mirrorgcrio/$imageName
        docker tag mirrorgcrio/$imageName k8s.gcr.io/$imageName
        docker rmi mirrorgcrio/$imageName
    done

然后执行

sh images.sh

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 13][]

慢慢拉镜像

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 14][]

再次执行初始化工作：

kubeadm init --apiserver-advertise-address=192.168.8.200 \
    --control-plane-endpoint="192.168.8.200:6443" \
     --kubernetes-version v1.18.3 \
     --service-cidr=10.1.0.0/16 \
     --pod-network-cidr=10.244.0.0/16 \
     --ignore-preflight-errors all

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2RvbmcxOTg5MTIxMA_size_16_color_FFFFFF_t_70 15][]

然后按照提示设置普通账户权限

mkdir -p $HOME/.kube
    cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
    chown $(id -u):$(id -g) $HOME/.kube/config

接着部署网络插件flannel

创建网络配置文件kube-flannel.yml

终于升级到了最新版！！！

建议裸机安装，不要像我一样用装过docker和kubernetes旧版本的机器，这老外天天改动，有出入，就像spring新版和老版本并不完全兼容，追人家的永远都受制于人！！！！！！

小结：不建议此种方式安装升级，还是以前源码式安装比较牢靠。
