一. 為什么是k8s v1.16.0？

最新版的v1.16.2試過(guò)了，一直無(wú)法安裝完成，安裝到kubeadm init那一步執(zhí)行后，報(bào)了很多錯(cuò)，如：node xxx not found等。centos7都重裝了幾次，還是無(wú)法解決。用了一天都沒安裝完，差點(diǎn)放棄。

后來(lái)在網(wǎng)上搜到的安裝教程基本都是v1.16.0的，我不太相信是v1.16.2的坑所以先前沒打算降級(jí)到v1.16.0。沒辦法了就試著安裝v1.16.0版本，竟然成功了。記錄在此，避免后來(lái)者踩坑。

本篇文章，安裝大步驟如下：

安裝docker-ce 18.09.9（所有機(jī)器）
設(shè)置k8s環(huán)境前置條件（所有機(jī)器）
安裝k8s v1.16.0 master管理節(jié)點(diǎn)
安裝k8s v1.16.0 node工作節(jié)點(diǎn)
安裝flannel（master）

這里有重要的一步，請(qǐng)記住自己master和node之間通信的ip，如我的master的ip為192.168.99.104，node的ip為：192.168.99.105. 請(qǐng)確保使用這兩個(gè)ip在master和node上能互相ping通，這個(gè)master的ip 192.168.99.104接下來(lái)配置k8s的時(shí)候需要用到。

我的環(huán)境：

操作系統(tǒng)：win10
虛擬機(jī)：virtual box
linux發(fā)行版：CentOS7
linux內(nèi)核(使用uname -r查看)：3.10.0-957.el7.x86_64
master和node節(jié)點(diǎn)通信的ip(master)：192.168.99.104

二. 安裝docker-ce 18.09.9（所有機(jī)器）

所有安裝k8s的機(jī)器都需要安裝docker，命令如下：

#?安裝docker所需的工具
yum install -y yum-utils device-mapper-persistent-data lvm2
#?配置阿里云的docker源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
#?指定安裝這個(gè)版本的docker-ce
yum install -y docker-ce-18.09.9-3.el7
#?啟動(dòng)docker
systemctl enable docker && systemctl start docker

三. 設(shè)置k8s環(huán)境準(zhǔn)備條件（所有機(jī)器）

安裝k8s的機(jī)器需要2個(gè)CPU和2g內(nèi)存以上，這個(gè)簡(jiǎn)單，在虛擬機(jī)里面配置一下就可以了。然后執(zhí)行以下腳本做一些準(zhǔn)備操作。所有安裝k8s的機(jī)器都需要這一步操作。

#?關(guān)閉防火墻
systemctl disable firewalld
systemctl stop firewalld

#?關(guān)閉selinux
#?臨時(shí)禁用selinux
setenforce 0
#?永久關(guān)閉 修改/etc/sysconfig/selinux文件設(shè)置
sed -i 's/SELINUX=permissive/SELINUX=disabled/' /etc/sysconfig/selinux
sed -i "s/SELINUX=enforcing/SELINUX=disabled/g" /etc/selinux/config

#?禁用交換分區(qū)
swapoff -a
#?永久禁用，打開/etc/fstab注釋掉swap那一行。
sed -i 's/.*swap.*/#&/' /etc/fstab

#?修改內(nèi)核參數(shù)
cat < /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables = 1
net.bridge.bridge-nf-call-iptables = 1
EOF
sysctl --system

四. 安裝k8s v1.16.0 master管理節(jié)點(diǎn)

如果還沒安裝docker，請(qǐng)參照本文步驟二安裝docker-ce 18.09.9（所有機(jī)器）安裝。

如果沒設(shè)置k8s環(huán)境準(zhǔn)備條件，請(qǐng)參照本文步驟三設(shè)置k8s環(huán)境準(zhǔn)備條件（所有機(jī)器）執(zhí)行。

以上兩個(gè)步驟檢查完畢之后，繼續(xù)以下步驟。

1. 安裝kubeadm、kubelet、kubectl

由于官方k8s源在google，國(guó)內(nèi)無(wú)法訪問(wèn)，這里使用阿里云yum源

# 執(zhí)行配置k8s阿里云源
cat?< /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kubeadm、kubectl、kubelet
yum install -y?kubectl-1.16.0-0?kubeadm-1.16.0-0?kubelet-1.16.0-0

# 啟動(dòng)kubelet服務(wù)
systemctl enable kubelet && systemctl start kubelet

2. 初始化k8s

以下這個(gè)命令開始安裝k8s需要用到的docker鏡像，因?yàn)闊o(wú)法訪問(wèn)到國(guó)外網(wǎng)站，所以這條命令使用的是國(guó)內(nèi)的阿里云的源(registry.aliyuncs.com/google_containers)。

另一個(gè)非常重要的是：這里的--apiserver-advertise-address使用的是master和node間能互相ping通的ip，我這里是192.168.99.104，剛開始在這里被坑了一個(gè)晚上，你請(qǐng)自己修改下ip執(zhí)行。

這條命令執(zhí)行時(shí)會(huì)卡在[preflight] You can also perform this action in beforehand using ''kubeadm config images pull，大概需要2分鐘，請(qǐng)耐心等待。

#?下載管理節(jié)點(diǎn)中用到的6個(gè)docker鏡像，你可以使用docker images查看到
#?這里需要大概兩分鐘等待，會(huì)卡在[preflight] You can also perform this action?in?beforehand using?''kubeadm config images pull
kubeadm init --image-repository registry.aliyuncs.com/google_containers --kubernetes-version v1.16.0 --apiserver-advertise-address 192.168.99.104 --pod-network-cidr=10.244.0.0/16 --token-ttl 0

上面安裝完后，會(huì)提示你輸入如下命令，復(fù)制粘貼過(guò)來(lái)，執(zhí)行即可。

# 上面安裝完成后，k8s會(huì)提示你輸入如下命令，執(zhí)行
mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config

3. 記住node加入集群的命令

上面kubeadm init執(zhí)行成功后會(huì)返回給你node節(jié)點(diǎn)加入集群的命令，等會(huì)要在node節(jié)點(diǎn)上執(zhí)行，需要保存下來(lái)，如果忘記了，可以使用如下命令獲取。

kubeadm token create --print-join-command

以上，安裝master節(jié)點(diǎn)完畢。可以使用kubectl get nodes查看一下，此時(shí)master處于NotReady狀態(tài)，暫時(shí)不用管。

五. 安裝k8s v1.16.0 node工作節(jié)點(diǎn)

如果還沒安裝docker，請(qǐng)參照本文步驟二安裝docker-ce 18.09.9（所有機(jī)器）安裝。

如果沒設(shè)置k8s環(huán)境準(zhǔn)備條件，請(qǐng)參照本文步驟三設(shè)置k8s環(huán)境準(zhǔn)備條件（所有機(jī)器）執(zhí)行。

以上兩個(gè)步驟檢查完畢之后，繼續(xù)以下步驟。

1. 安裝kubeadm、kubelet

# 執(zhí)行配置k8s阿里云源
cat?< /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kubeadm、kubectl、kubelet
yum install -y??kubeadm-1.16.0-0?kubelet-1.16.0-0

# 啟動(dòng)kubelet服務(wù)
systemctl enable kubelet && systemctl start kubelet

2. 加入集群

這里加入集群的命令每個(gè)人都不一樣，可以登錄master節(jié)點(diǎn)，使用kubeadm token create --print-join-command 來(lái)獲取。獲取后執(zhí)行如下。

# 加入集群，如果這里不知道加入集群的命令，可以登錄master節(jié)點(diǎn)，使用kubeadm token create --print-join-command?來(lái)獲取?
kubeadm?join?192.168.99.104:6443?--token ncfrid.7ap0xiseuf97gikl \
????--discovery-token-ca-cert-hash?sha256:47783e9851a1a517647f1986225f104e81dbfd8fb256ae55ef6d68ce9334c6a2

加入成功后，可以在master節(jié)點(diǎn)上使用kubectl get nodes命令查看到加入的節(jié)點(diǎn)。

六. 安裝flannel（master機(jī)器）

以上步驟安裝完后，機(jī)器搭建起來(lái)了，但狀態(tài)還是NotReady狀態(tài)，如下圖，master機(jī)器需要安裝flanneld。

1. 下載官方fannel配置文件

使用wget命令，地址為：(https://raw.githubusercontent.com/coreos/flannel/master/Documentation/kube-flannel.yml)，這個(gè)地址國(guó)內(nèi)訪問(wèn)不了，所以我把內(nèi)容復(fù)制下來(lái)，為了避免前面文章過(guò)長(zhǎng)，我把它粘貼到文章末尾第八個(gè)步驟附錄了。

這個(gè)yml配置文件中配置了一個(gè)國(guó)內(nèi)無(wú)法訪問(wèn)的地址(quay.io)，我已經(jīng)將其改為國(guó)內(nèi)可以訪問(wèn)的地址(quay-mirror.qiniu.com)。我們新建一個(gè)kube-flannel.yml文件，復(fù)制粘貼該內(nèi)容即可。

2. 安裝fannel

kubectl?apply?-f?kube-flannel.yml

七. 大功告成

至此，k8s集群搭建完成，如下圖節(jié)點(diǎn)已為Ready狀態(tài)，大功告成，完結(jié)撒花。

八. 附錄

這是kube-flannel.yml文件的內(nèi)容，已經(jīng)將無(wú)法訪問(wèn)的地址(quay.io)全部改為國(guó)內(nèi)可以訪問(wèn)的地址(quay-mirror.qiniu.com)。我們新建一個(gè)kube-flannel.yml文件，復(fù)制粘貼該內(nèi)容即可。
