|NO.Z.00027|——————————|^^ 部署 ^^|——|Kubernetes&高可用集群.V01|——|环境准备|

一、kubernetes集群搭建-高可用集群

二、部署规划

---

一、基础环境配置

### --- 关闭防火墙

[root@server11 ~]# systemctl stop firewalld
[root@server11 ~]# systemctl disable firewalld

### --- 关闭selinux

[root@server11 ~]# sed -i 's/enforcing/disabled/' /etc/selinux/config  # 永久
setenforce 0                                                           # 临时

### --- 关闭swap

[root@server11 ~]# swapoff -a                                       	# 临时
[root@server11 ~]# sed -ri 's/.*swap.*/#&/' /etc/fstab              	# 永久 

### --- 根据规划设置主机名

[root@server11 ~]# hostnamectl set-hostname k8s-master1
[root@server12 ~]# hostnamectl set-hostname k8s-master2
[root@server13 ~]# hostnamectl set-hostname k8s-node1

### --- 在master添加hosts

[root@k8s-master1 ~]# cat >> /etc/hosts << EOF
> 10.10.10.15    master.k8s.io   k8s-vip
> 10.10.10.11    master01.k8s.io k8s-master1
> 10.10.10.12    master02.k8s.io k8s-master2
> 10.10.10.13    node01.k8s.io   k8s-node1
> EOF

[root@k8s-master2 ~]# cat >> /etc/hosts << EOF
> 10.10.10.15    master.k8s.io   k8s-vip
> 10.10.10.11    master01.k8s.io k8s-master1
> 10.10.10.12    master02.k8s.io k8s-master2
> 10.10.10.13    node01.k8s.io   k8s-node1
> EOF

### --- 将桥接的IPv4流量传递到iptables的链

[root@k8s-master1 ~]# cat > /etc/sysctl.d/k8s.conf << EOF
> net.bridge.bridge-nf-call-ip6tables = 1
> net.bridge.bridge-nf-call-iptables = 1
> EOF
[root@k8s-master2 ~]# cat > /etc/sysctl.d/k8s.conf << EOF
> net.bridge.bridge-nf-call-ip6tables = 1
> net.bridge.bridge-nf-call-iptables = 1
> EOF
[root@k8s-node1 ~]# cat > /etc/sysctl.d/k8s.conf << EOF
> net.bridge.bridge-nf-call-ip6tables = 1
> net.bridge.bridge-nf-call-iptables = 1
> EOF

~~~     生效

[root@k8s-master1 ~]# sysctl --system 
[root@k8s-master2 ~]# sysctl --system 
[root@k8s-node1 ~]# sysctl --system 

### --- 时间同步

[root@k8s-master1 ~]# yum install ntpdate -y
[root@k8s-master2 ~]# yum install ntpdate -y
[root@k8s-node1 ~]# yum install ntpdate -y

[root@k8s-master1 ~]# ntpdate time.windows.com
24 Feb 19:06:54 ntpdate[11087]: step time server 20.189.79.72 offset -1.957517 sec
[root@k8s-master2 ~]# ntpdate time.windows.com
24 Feb 19:06:56 ntpdate[10250]: step time server 20.189.79.72 offset -1.956963 sec
[root@k8s-node1 ~]# ntpdate time.windows.com
24 Feb 19:06:58 ntpdate[10264]: step time server 20.189.79.72 offset -1.958099 sec
