1,安裝docker

64 位版本的 CentOS 7
CentOS 系統(tǒng)的內(nèi)核版本高于 3.10（uname -r命令可查看系統(tǒng)內(nèi)核版本）
安裝 Docker CE

設(shè)置 Docker 的鏡像倉庫并從中進(jìn)行安裝
下載 RPM 軟件包并手動(dòng)進(jìn)行安裝（例如隆判，在不能訪問互聯(lián)網(wǎng)的隔離系統(tǒng)中安裝 Docker）
1.從鏡像倉庫安裝

確保 yum 包更新到最新:

sudo yum update

安裝一些必要的系統(tǒng)工具：

yum-utils 提供了 yum-config-manager 實(shí)用程序，用于設(shè)置yum源
devicemapper 存儲(chǔ)驅(qū)動(dòng)需要 device-mapper-persistent-data 和 lvm2

    sudo yum install -y yum-utils device-mapper-persistent-data lvm2

設(shè)置鏡像倉庫：

阿里云倉庫地址（推薦）

sudo yum-config-manager \
 --add-repo \
   http://mirrors.aliyun.com/docker-ce/linux/centos/docker-      ce.repo

官方倉庫地址

sudo yum-config-manager \
 --add-repo \
   https://download.docker.com/linux/centos/docker-ce.repo

更新 yum 軟件包索引僧界。

sudo yum makecache fast

查看倉庫中所有docker版本

sudo yum list docker-ce --showduplicates | sort -r

安裝 Docker CE 最新版本：sudo yum install docker-ce

sudo yum install docker-ce

安裝 Docker-ce 指定版本：sudo yum install docker-ce-版本號(hào)

sudo yum -y install docker-ce-18.03.1.ce-1.el7.centos

啟動(dòng) Docker

sudo systemctl start docker 啟動(dòng)
sudo systemctl restart docker 重啟
sudo systemctl enable docker 加入開機(jī)啟動(dòng)

Docker 版本信息查看

sudo docker version

測(cè)試運(yùn)行 hello-world

sudo docker run hello-world

docekr拉取hello-world鏡像并啟動(dòng)蜜氨，后打印出Hello from Docker!

查看安裝的docker

yum list installed | grep docker

卸載 Docker CE

sudo yum remove docker-ce

刪除所有鏡像、容器和存儲(chǔ)卷

sudo rm -rf /var/lib/docker

2.0 安裝golang：

下載安裝包捎泻，國內(nèi)地址：https://studygolang.com/dl/golang/go1.14.4.linux-amd64.tar.gz

$ sudo tar -C /usr/local -xzf go1.12.5.linux-amd64.tar.gz  //解壓

添加環(huán)境變量飒炎，修改/etc/profile 或$HOME/.profile或/etc/profile.d/目錄的文件

$ sudo vi /etc/profile.d/brianconfig.sh  //添加以下內(nèi)容
export GOROOT=/usr/local/go //定義GOROOT
export PATH=$PATH:/usr/local/go/bin // 添加go/bin到系統(tǒng)環(huán)境變量PATH中
export GOPATH=/home/gopath //添加GOPATH變量

查看golang版本：

$ go version
go version go1.12.5 linux/amd64

查看GOROOT

$ go env GOROOT
/usr/local/go

查看GOPATH

$ echo $GOPATH
/
/home/gopath

3.0 安裝node：

1、從官網(wǎng)下下載最新的nodejs笆豁，https://nodejs.org/dist/v12.18.2/node-v12.18.2-linux-x64.tar.xz

image

歷史版本可從https://nodejs.org/dist/下載

2郎汪、解壓安裝包

tar -xvf node-v10.16.0-linux-x64.tar.xz

sudo tar -C /usr/local -xzf go1.14.4.linux-amd64.tar.gz

3、移動(dòng)并改名文件夾（不改名也行）

cd /usr/local/

mv node-v12.18.2-linux-x64 /usr/local/
mv node-v10.16.0.0-linux-64/ nodejs

image

4闯狱、讓npm和node命令全局生效

軟鏈接方式（推薦）

ln -s /usr/local/nodejs/bin/npm /usr/local/bin/ 

ln -s /usr/local/nodejs/bin/node /usr/local/bin/

5煞赢、查看nodejs是否安裝成功

node -v
npm -v

image

4.0. 安裝k8s

1 系統(tǒng)準(zhǔn)備

查看系統(tǒng)版本

[root@localhost]# cat /etc/centos-release
CentOS Linux release 8.1.1911 (Core)

配置網(wǎng)絡(luò)

[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp0s3

NETMASK=255.255.255.0
GATEWAY=192.168.122.1
DNS1=223.5.5.5

添加阿里源

[root@localhost ~]# rm -rfv /etc/yum.repos.d/*
[root@localhost ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo

配置主機(jī)名

[root@master01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.122.21 master01.paas.com master01

關(guān)閉swap，注釋swap分區(qū)

[root@master01 ~]# swapoff -a
[root@master01 ~]# cat /etc/fstab

#
# /etc/fstab
# Created by anaconda on Tue Mar 31 22:44:34 2020

#/dev/mapper/cl-swap     swap                    swap    defaults        0 0

配置內(nèi)核參數(shù)哄孤，將橋接的IPv4流量傳遞到iptables的鏈

[root@master01 ~]# cat > /etc/sysctl.d/k8s.conf <<EOF
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system

2 安裝常用包

[root@master01 ~]# yum install vim bash-completion net-tools gcc -y

4 安裝kubectl照筑、kubelet、kubeadm

添加阿里kubernetes源

[root@master01 ~]# 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

安裝

[root@master01 ~]# yum install kubectl kubelet kubeadm
[root@master01 ~]# systemctl enable kubelet

5 初始化k8s集群

image.png

[root@master01 ~]# kubeadm init --kubernetes-version=1.18.0  \
--apiserver-advertise-address=192.168.122.21   \
--image-repository registry.aliyuncs.com/google_containers  \
--service-cidr=10.10.0.0/16 --pod-network-cidr=10.122.0.0/16

POD的網(wǎng)段為: 10.122.0.0/16瘦陈， api server地址就是master本機(jī)IP凝危。

這一步很關(guān)鍵，由于kubeadm 默認(rèn)從官網(wǎng)k8s.grc.io下載所需鏡像晨逝，國內(nèi)無法訪問蛾默，因此需要通過–image-repository指定阿里云鏡像倉庫地址。

集群初始化成功后返回如下信息：

Your Kubernetes control-plane has initialized successfully!

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 192.168.122.21:6443 --token v2r5a4.veazy2xhzetpktfz \
    --discovery-token-ca-cert-hash sha256:daded8514c8350f7c238204979039ff9884d5b595ca950ba8bbce80724fd65d4

記錄生成的最后部分內(nèi)容捉貌，此內(nèi)容需要在其它節(jié)點(diǎn)加入Kubernetes集群時(shí)執(zhí)行支鸡。
根據(jù)提示創(chuàng)建kubectl

[root@master01 ~]#  mkdir -p $HOME/.kube
[root@master01 ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
[root@master01 ~]#   sudo chown $(id -u):$(id -g) $HOME/.kube/config

5,部署區(qū)塊鏈網(wǎng)絡(luò)

git clone git@github.com:IBM/blockchain-network-on-kubernetes.git
chmod +x setup_blockchainNetwork.sh
chmod +x deleteNetwork.sh
./setup_blockchainNetwork.sh

當(dāng)一切都完成之后：
