1.1 升级内核
rpm -Uvh http://www.elrepo.org/elrepo-release-7.0-2.el7.elrepo.noarch.rpm ;yum --enablerepo=elrepo-kernel install kernel-lt-devel kernel-lt -y
#查看默认启动顺序
awk -F\‘ ‘$1=="menuentry " {print $2}‘ /etc/grub2.cfg
CentOS Linux (4.4.4-1.el7.elrepo.x86_64) 7 (Core)
CentOS Linux (3.10.0-327.10.1.el7.x86_64) 7 (Core)
CentOS Linux (0-rescue-c52097a1078c403da03b8eddeac5080b) 7 (Core)
#默认启动的顺序是从0开始，新内核是从头插入（目前位置在0，而4.4.4的是在1），所以需要选择0。
grub2-set-default 0
#重启
reboot
#检查内核，成功升级到4.4
uname -a
Linux bigdata5 4.4.104-1.el7.elrepo.x86_64 #1 SMP Tue Dec 5 12:46:32 EST 2017 x86_64 x86_64 x86_64 GNU/Linux
1.2 所有节点安装Docker, 修改文件系统为ovelay2驱动
#安装docker
yum install docker-common-1.12.6 docker-client-1.12.6 docker-1.12.6-61 -y
#设置文件系统为ovelay2驱动
cat /etc/docker/daemon.json
{
"storage-driver": "overlay2"
}
1.3 所有节点安装ipvsadm
yum install ipvsadm -y
####注意所有的文件由master ingest01这台机下发，配置ssh信任所有机器
####下载目录为/root/
[root@ingest01 ~]# pwd
/root
wget https://dl.k8s.io/v1.9.0/kubernetes-server-linux-amd64.tar.gz
wget https://github.com/coreos/etcd/releases/download/v3.2.11/etcd-v3.2.11-linux-amd64.tar.gz
wget https://github.com/coreos/flannel/releases/download/v0.9.0/flannel-v0.9.0-linux-amd64.tar.gz
3.1 解压
tar xvf kubernetes-server-linux-amd64.tar.gz && tar xvf etcd-v3.2.11-linux-amd64.tar.gz && tar xvf flannel-v0.9.0-linux-amd64.tar.gz
3.2 创建node，master ,etcd所需的二进制目录并进行归类
mkdir -p /root/kubernetes/server/bin/{node,master,etcd}
mv /root/kubernetes/server/bin/kubelet /root/kubernetes/server/bin/node/
mv /root/mk-docker-opts.sh /root/kubernetes/server/bin/node/
mv /root/flanneld /root/kubernetes/server/bin/node/
mv /root/kubernetes/server/bin/kube-* /root/kubernetes/server/bin/master/
mv /root/kubernetes/server/bin/kubelet /root/kubernetes/server/bin/master/
mv /root/kubernetes/server/bin/kubectl /root/kubernetes/server/bin/master/
mv /root/etcd-v3.2.4-linux-amd64/etcd* /root/kubernetes/server/bin/etcd/
3.3 下发node以及flanneld二进制文件
for node in bigdata3 bigdata4 bigdata5 ingest01;do
rsync -avzP /root/kubernetes/server/bin/node/ ${node}:/usr/local/bin/
done
3.4 下发master 二进制文件
for master in ingest01 ingets01 ingest03;do
rsync -avzP /root/kubernetes/server/bin/master/ ${master}:/usr/local/bin/
done
3.5 下发etcd文件
for etcd in etcd01 etcd02 etcd03;do
rsync -avzP /root/kubernetes/server/bin/etcd/ ${etcd}:/usr/local/bin/
done
4.1 创建服务归类文件夹
mkdir -p /root/kubernetes/server/bin/{node-service,master-service,etcd-service,docker-service,ssl}
4.2 创建node 所需的文件
#docker.service
cat >/root/kubernetes/server/bin/node-service/docker.service <<‘HERE‘
