软件需求
需求项 | 具体要求 | 检查命令 |
---|---|---|
操作系统 | CentOS 7.9 64 位 | cat /etc/centos-release |
kernel | 3.10.0 及以上 | uname -r |
Swap | 关闭。防止 io 飙升影响 kubelet 进程。 |
free -m Swap 这行值为 0 |
防火墙 | 关闭 |
iptables -vnL 无其他规则 |
SELinux | 关闭。k8s 官方要求。 |
getenforce 的输出为 Disabled |
时区 | 所有服务器时区应该统一,建议使用北京时间 | 使用 timedatectl set-timezone Asia/Shanghai 设置为北京时间。 |
时间同步 | etcd 选举时要求节点间时间差小于 1s | 配置 chronyd 同步时间 |
docker 版本 | 19.03 及更高 | docker version |
kubenetes 版本 | 限 1.18 或 1.20,其他版本未经测试。用户报告 1.22 以上版本不兼容,1.17 版本部署 bcs 会失败。 | kubectl version |

在执行
curl -fsSL https://bkopen-1252002024.file.myqcloud.com/ce7/bcs.sh | bash -s -- install k8s-node
或者
./bcs.sh -i k8s-node
查看集群
使用命令
kubectl get node
或者
kubectl get node -o wide
会出现的问题
出先The connection to the server localhost:8080 was refused - did you specify the right host or port?的错误信息。
#从主master节点复制admin.conf到有问题的机器
scp /etc/kubernetes/admin.conf 192.168.10.42:/etc/kubernetes/admin.conf
输入密码

传过去后,在有问题机器输入文章来源地址https://www.toymoban.com/news/detail-704291.html
echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile
source ~/.bash_profile
