一、安裝docker
提示：所有節點都要安裝docker
注：此實驗環境是三臺伺服器:linux-node1、linux-node2、linux-node3
第一步：按裝Docker
#使用國內docker源
[email protected] ~]# cd /etc/yum.repos.d/ [[email protected]-node1 yum.repos.d]# wget https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
第二步：安裝docker
[[email protected]yum.repos.d]# cd ~ [[email protected]-node1 ~]# yum install -y docker-ce [[email protected]-node1 ~]# echo $? 0
第三步：啟動後臺程序
#啟動服務
[[email protected] ~]# systemctl start docker
#檢視服務狀態
[[email protected] ~]# systemctl status docker
二、準備部署目錄
提示：所有節點都要建立此目錄
[[email protected]~]# mkdir -p /opt/kubernetes/{cfg,bin,ssl,log} [[email protected]-node1 ~]# tree /opt/kubernetes/ /opt/kubernetes/ ├── bin #存放二進位制檔案 ├── cfg #存放配置檔案 ├── log #存放日誌檔案 └── ssl #存放證書檔案 4 directories, 0 files
三、準備軟體包
官方軟體包(生產環境)：https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG-1.10.md連結:https://pan.baidu.com/s/1N6fjJMEjkQNYnRjExC2WWQ 密碼:9wf6 [[email protected]node1 src]# rz rz waiting to receive.**B0100000023be50 [[email protected]-node1 src]# [[email protected]-node1 src]# du -sh k8s-v1.10.1-manual.zip 567M k8s-v1.10.1-manual.zip
四、解壓軟體包
安裝解壓縮工具
[[email protected] src]# yum -y install unzip
[[email protected]node1 src]# ls k8s-v1.10.1-manual.zip [[email protected]-node1 src]# unzip k8s-v1.10.1-manual.zip Archive: k8s-v1.10.1-manual.zip creating: k8s-v1.10.1-manual/ creating: k8s-v1.10.1-manual/k8s-v1.10.1/ inflating: k8s-v1.10.1-manual/k8s-v1.10.1/cfssl-certinfo_linux-amd64 inflating: k8s-v1.10.1-manual/k8s-v1.10.1/cfssl_linux-amd64 inflating: k8s-v1.10.1-manual/k8s-v1.10.1/cfssljson_linux-amd64 inflating: k8s-v1.10.1-manual/k8s-v1.10.1/cni-plugins-amd64-v0.7.1.tgz inflating: k8s-v1.10.1-manual/k8s-v1.10.1/etcd-v3.2.18-linux-amd64.tar.gz inflating: k8s-v1.10.1-manual/k8s-v1.10.1/flannel-v0.10.0-linux-amd64.tar.gz inflating: k8s-v1.10.1-manual/k8s-v1.10.1/kubernetes-client-linux-amd64.tar.gz inflating: k8s-v1.10.1-manual/k8s-v1.10.1/kubernetes-node-linux-amd64.tar.gz inflating: k8s-v1.10.1-manual/k8s-v1.10.1/kubernetes-server-linux-amd64.tar.gz inflating: k8s-v1.10.1-manual/k8s-v1.10.1/kubernetes.tar.gz [[email protected]-node1 src]# ls k8s-v1.10.1-manual k8s-v1.10.1-manual.zip [[email protected]-node1 src]# cd k8s-v1.10.1-manual/k8s-v1.10.1/ [[email protected]-node1 k8s-v1.10.1]# ll -l total 599096 -rw-r--r-- 1 root root 6595195 Mar 30 2016 cfssl-certinfo_linux-amd64 -rw-r--r-- 1 root root 2277873 Mar 30 2016 cfssljson_linux-amd64 -rw-r--r-- 1 root root 10376657 Mar 30 2016 cfssl_linux-amd64 -rw-r--r-- 1 root root 17108856 Apr 12 17:35 cni-plugins-amd64-v0.7.1.tgz -rw-r--r-- 1 root root 10562874 Mar 30 01:58 etcd-v3.2.18-linux-amd64.tar.gz -rw-r--r-- 1 root root 9706487 Jan 24 02:58 flannel-v0.10.0-linux-amd64.tar.gz -rw-r--r-- 1 root root 13344537 Apr 13 01:51 kubernetes-client-linux-amd64.tar.gz -rw-r--r-- 1 root root 112427817 Apr 13 01:51 kubernetes-node-linux-amd64.tar.gz -rw-r--r-- 1 root root 428337777 Apr 13 01:51 kubernetes-server-linux-amd64.tar.gz -rw-r--r-- 1 root root 2716855 Apr 13 01:51 kubernetes.tar.gz [[email protected]-node1 k8s-v1.10.1]# [[email protected]-node1 k8s-v1.10.1]# tar zxf kubernetes.tar.gz #k8s原始碼包 [[email protected]-node1 k8s-v1.10.1]# tar zxf kubernetes-server-linux-amd64.tar.gz [[email protected]-node1 k8s-v1.10.1]# tar zxf kubernetes-client-linux-amd64.tar.gz [[email protected]-node1 k8s-v1.10.1]# tar zxf kubernetes-node-linux-amd64.tar.gz #把所有包移動至/usr/local/src/目錄下 [[email protected]-node1 k8s-v1.10.1]# mv * /usr/local/src/ [[email protected]-node1 k8s-v1.10.1]# cd /usr/local/src/ [[email protected]-node1 src]# ls -l total 1178908 -rw-r--r-- 1 root root 6595195 Mar 30 2016 cfssl-certinfo_linux-amd64 -rw-r--r-- 1 root root 2277873 Mar 30 2016 cfssljson_linux-amd64 -rw-r--r-- 1 root root 10376657 Mar 30 2016 cfssl_linux-amd64 -rw-r--r-- 1 root root 17108856 Apr 12 17:35 cni-plugins-amd64-v0.7.1.tgz -rw-r--r-- 1 root root 10562874 Mar 30 01:58 etcd-v3.2.18-linux-amd64.tar.gz -rw-r--r-- 1 root root 9706487 Jan 24 02:58 flannel-v0.10.0-linux-amd64.tar.gz drwxr-xr-x 3 root root 25 Apr 23 20:19 k8s-v1.10.1-manual -rw-r--r-- 1 root root 593725046 May 29 17:01 k8s-v1.10.1-manual.zip drwxr-xr-x 11 root root 211 Apr 12 23:16 kubernetes -rw-r--r-- 1 root root 13344537 Apr 13 01:51 kubernetes-client-linux-amd64.tar.gz -rw-r--r-- 1 root root 112427817 Apr 13 01:51 kubernetes-node-linux-amd64.tar.gz -rw-r--r-- 1 root root 428337777 Apr 13 01:51 kubernetes-server-linux-amd64.tar.gz -rw-r--r-- 1 root root 2716855 Apr 13 01:51 kubernetes.tar.gz
五、新增PATH路徑
提示：所有節點都要執行此操作
[[email protected] k8s-v1.10.1]# vim ~/.bash_profile PATH=$PATH:$HOME/bin:/opt/kubernetes/bin [[email protected]-node1 k8s-v1.10.1]# source ~/.bash_profile
六、ssh免密碼登入
[[email protected] ~]# ssh-keygen -t rsa Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory '/root/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: 82:a2:ae:56:9a:1f:a6:74:ab:cb:08:1b:7d:51:6c:a4 [email protected]node1.example.com The key's randomart image is: +--[ RSA 2048]----+ | . | | + | | E + | | + | | . o .
