标签：dn scm Kerberos ozone etc apache COM EXAMPLE

环境说明

  1. 采用docker + compose方式运行
  2. Ozone镜像选择apache/ozone:1.4.0
  3. kerberos部署于宿主机上（Rocky Linux 9.4）
  4. 宿主机主机名：ozone.example.com，ip：192.168.121.128

设置S3 Secret

由于启用了安全配置，通过S3访问必须使用Secret才行，下面通过命名获取s3g/s3g@EXAMPLE.COM对应的Secret：

[root@ozone ozone]# docker exec -it ozone-s3g-1 bash
bash-4.2$ kinit -kt /etc/security/keytabs/ozone.keytab s3g/s3g@EXAMPLE.COM
bash-4.2$ klist
