离线安装 DCE 5.0 商业版¶
本页简要说明 DCE 5.0 商业版的离线安装步骤。
准备工作¶
-
准备一台火种机器,安装依赖项
Note
- 火种机器是安装 DCE 5.0 的前提,DCE 5.0 商业版所有的资源都将通过火种机器执行安装部署。
- 火种机器最低配置:CPU > 4 核、内存 > 8 GB、磁盘空间 > 100 GB
-
如果已安装所有依赖项,请确保依赖项版本符合要求:
- podman
- helm ≥ 3.9.1
- skopeo ≥ 1.9.2
- kind
- kubectl ≥ 1.22.0
- yq ≥ 4.27.5
- minio client
-
执行
systemctl stop firewalld
来关闭机器上的防火墙服务
-
准备至少一台管理集群(Management)节点,一台全局服务集群(Global)节点(简约模式下可以将二者合并)
Note
- Global 集群的节点(可运行 DCE5 组件的节点)需要有至少一块没有分区的磁盘,总大小约 200G
- Global 集群需要 3 台控制平面节点(Master 节点),工作节点最低配置:CPU > 8 核、内存 > 16 GB
- Management 集群单节点最低配置:CPU > 4 核、内存 > 4 GB(建议生产环境使用高可用的模式)
- 确保所有节点的时间同步,否则安装结束后,kube.conf 会报错
Unable to connect to the server: x509: certificate has expired or is not yet
- 确保所有节点的
/etc/resolv.conf
至少有一个 nameserver,否则 coredns 报错plugin/forward: no nameservers found
离线安装¶
-
在火种机器上下载 dce5-installer 二进制文件。
# 假定 VERSION 为 v0.3.24 export VERSION=v0.3.24 curl -Lo ./dce5-installer https://proxy-qiniu-download-public.daocloud.io/DaoCloud_Enterprise/dce5/dce5-installer-$VERSION
为
dce5-installer
添加可执行权限: -
在火种机器上下载 offline 离线镜像包并解压。
-
设置集群配置文件 clusterConfig.yaml,可以在离线包
offline/sample
下获取该文件并按需修改。配置文件范例如下:

-
安装 DCE 5.0。
./dce5-installer cluster-create -c ./offline/sample/clusterConfig.yaml -m ./offline/sample/manifest.yaml -p ./offline/
Note
命令需要指定
-m
参数,manifest.yaml 文件在离线包offline/sample
下。 -
安装完成后,命令行会提示安装成功。恭喜您! 现在可以通过屏幕提示的 URL 使用默认的账户和密码(admin/changeme)探索全新的 DCE 5.0 啦!
