博文摘要

博文主要描述了在 vCenter Server 8 上通过实用工具 certificate-manager 将 vSphere 默认 Machine SSL 证书替换为 企业 CA 自签名证书。适用的 vSphere 版本为 vSphere 7.0.x 和 vSphere 8.0.x

6. 使用企业 CA 签发的 SSL 证书 替换 vSphere 默认 SSL 证书

6.1 确认证书文件

SSH 到 VCSA 中，cd 到 /root/machine_ssl 目录，此时该目录存在4个文件

需要用到的是

• 自定义证书：machine_ssl.cer
• 自定义密钥：vmca_issued_key.key
• 签名证书：root-64.cer

6.2 替换默认 vSphere 证书

再次使用certificate-manager工具替换默认证书

File : /root/machine_ssl/machine_ssl.cerPlease provide valid custom key for Machine SSL.
File : /root/machine_ssl/vmca_issued_key.keyPlease provide the signing certificate of the Machine SSL certificate
File : /root/machine_ssl/root-64.cerYou are going to replace Machine SSL cert using custom cert
Continue operation : Option[Y/N] ? : Y
Command Output: /root/machine_ssl/machine_ssl.cer: OKStatus : 100% Completed [All tasks completed successfully]

此时 SSL 证书的更新状态是100%成功完成。

6.3 验证自签名证书

登录 vSphere Client，Menu > Administration > Certificastes > Certificate Management，找到 Machine SSL Certificate，点击VIEW DETAILS

此时 企业CA 直接签发的 Machine SSL 证书替换成功。

6.4 补充说明

我们替换的是 Machine SSL 证书，其它 VMCA 证书还是使用 vSphere 默认证书。

查看 VMware Certificate Authority 的 VMCA_ROOT_CERT 详细信息，显示内容依然和VMware相关：
