一、系统初始化
系统初始化参考：https://www.cnblogs.com/hujinzhong/p/12251486.html
节点准备：
| 节点 | ip |
| master01 | 10.0.0.11 |
| master02 | 10.0.0.12 |
| master03 | 10.0.0.13 |
| node01 | 10.0.0.21 |
| node02 | 10.0.0.22 |
| k8s-vip | 10.0.0.100 |
以一台master节点为例：
1）主机名及hosts解析
[root@master01 ~]# hostnamectl set-hostname k8s-master01 [root@master01 ~]# vim /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 10.0.0.11 master01 10.0.0.12 master02 10.0.0.13 master03 10.0.0.21 node01 10.0.0.22 node02 10.0.0.100 k8s-vip
2）安装依赖包
[root@master01 ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo [root@master01 ~]# yum install -y conntrack ntpdate ntp ipvsadm ipset jq iptables curl sysstat libseccomp wget vim net-tools git
3）防火墙/swap/selinux
#防火墙 [root@master01 ~]# systemctl stop firewalld && systemctl disable firewalld [root@master01 ~]# yum install -y iptables-services && systemctl start iptables && systemctl enable iptables &&iptables -F && service iptables save #selinix [root@master01 ~]# setenforce 0 && sed -i 's#^SELINUX=.*#SELINUX=disabled#g' /etc/selinux/config setenforce: SELinux is disabled [root@master01 ~]# getenforce Disabled #关闭swap [root@master01 ~]# swapoff -a && sed -r -i '/swap/s@(.*)@#\1@g' /etc/fstab
