第 6 章 使用 IdM Healthcheck 验证 KDC worker 进程的最佳数量

先决条件

• KDC worker 进程 Healthcheck 工具仅适用于 RHEL 8.7 或更新版本。
• 您必须以 root 用户身份执行 Healthcheck 测试。

流程

• 要运行对 KDC worker 进程的检查，请输入：

  # ipa-healthcheck --source ipahealthcheck.ipa.kdc

  如果 KDC worker 进程的数量与 CPU 核数匹配，则测试会返回 SUCCESS ：

  {
  	"source": "ipahealthcheck.ipa.kdc",
  	"check": "KDCWorkersCheck",
  	"result": "SUCCESS",
  	"uuid": "68f6e20a-0aa9-427d-8fdc-fbb8196d56cd",
  	"when": "20230105162211Z",
  	"duration": "0.000157",
  	"kw": {
    	"key": "workers"
  	}
  }

  如果 worker 进程数量与 CPU 核数不匹配，则测试会返回 WARNING。在以下示例中，带有 2 个核的主机被配置为只有一个 KDC worker 进程：

  {
      "source": "ipahealthcheck.ipa.kdc",
      "check": "KDCWorkersCheck",
      "result": "WARNING",
      "uuid": "972b7782-1616-48e0-bd5c-49a80c257895",
      "when": "20230105122236Z",
      "duration": "0.203049",
      "kw": {
        "key": ‘workers’,
        "cpus": 2,
        "workers": 1,
        "expected": "The number of CPUs {cpus} does not match the number of workers {workers} in {sysconfig}"
      }
  }

  如果没有配置的 worker，则测试也会输出 WARNING。在以下示例中，/etc/sysconfig/krb5kdc 配置文件中缺少 KRB5KDC_ARGS 变量：

    {
      "source": "ipahealthcheck.ipa.kdc",
      "check": "KDCWorkersCheck",
      "result": "WARNING",
      "uuid": "5d63ea86-67b9-4638-a41e-b71f4
  56efed7",
      "when": "20230105162526Z",
      "duration": "0.000135",
      "kw": {
        "key": "workers",
        "sysconfig": "/etc/sysconfig/krb5kdc",
        "msg": "KRB5KDC_ARGS is not set in {sysconfig}"
      }
    }
