部署Kubernetes云计算平台至少准备两台服务器服务器CPU至少2C内存4G环境如下所示
Kubernetes Master节点192.168.1.146
Kubernetes Minion节点192.168.1.147
2. K8S节点Hosts及防火墙设置
master1、node1节点进行如下配置
#添加hosts解析
cat /etc/hostsEOF
127.0.0.1 localhost localhost.localdomain
192.168.1.146 master1
192.168.1.147 node1
EOF
#临时关闭selinux和防火墙
sed -i /SELINUX/s/enforcing/disabled/g /etc/sysconfig/selinux
setenforce 0
systemctl stop firewalld.service
systemctl disable firewalld.service
#同步节点时间
yum install ntpdate -y
ntpdate pool.ntp.org
#修改对应节点主机名
hostname cat /etc/hosts|grep $(ifconfig|grep broadcast|awk {print $2})|awk {print $2};su
#关闭swapoff
swapoff -a3. Linux内核参数设置优化
cat /etc/modules-load.d/ipvs.conf EOF
# Load IPVS at boot
ip_vs
ip_vs_rr
ip_vs_wrr
ip_vs_sh
nf_conntrack_ipv4
EOF
systemctl enable --now systemd-modules-load.service
#确认内核模块加载成功
lsmod | grep -e ip_vs -e nf_conntrack_ipv4
#安装ipset、ipvsadm
yum install -y ipset ipvsadm
#配置内核参数;
cat EOF /etc/sysctl.d/k8s.conf
net.bridge.bridge-nf-call-ip6tables 1
net.bridge.bridge-nf-call-iptables 1
EOF
sysctl --system4. Docker虚拟化案例实战 # 安装依赖软件包
yum install -y yum-utils device-mapper-persistent-data lvm2
# 添加Docker repository这里使用国内阿里云yum源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 安装docker-ce这里直接安装最新版本
yum install -y docker-ce
#修改docker配置文件
mkdir /etc/docker
cat /etc/docker/daemon.json EOF
{exec-opts: [native.cgroupdriversystemd],log-driver: json-file,log-opts: {max-size: 100m},storage-driver: overlay2,storage-opts: [overlay2.override_kernel_checktrue],registry-mirrors: [https://uyah70su.mirror.aliyuncs.com]
}
EOF
# 注意由于国内拉取镜像较慢配置文件最后增加了registry-mirrors
mkdir -p /etc/systemd/system/docker.service.d
# 重启docker服务
systemctl daemon-reload
systemctl enable docker.service
systemctl start docker.service
ps -ef|grep -aiE docker5. Kubernetes添加部署源
Kubernetes Master节点上安装Docker、Etcd和Kubernetes、Flannel网络添加kubernetes源指令如下
cat/etc/yum.repos.d/kubernetes.repoEOF
[kubernetes]
nameKubernetes
baseurlhttps://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64
enabled1
gpgcheck0
