1.4. 同时在多个系统中生成和收集 sos 报告

先决条件

• 您知道 要运行的 机器类型或 节点列表。
• 您已在所有系统上安装 sos 软件包。
• 您拥有所有系统中 root 帐户的 ssh 密钥，或者您可以通过 --password 选项提供 root 密码。

流程

• 运行 sos collect 命令并按照屏幕的说明进行操作。

  注意

  默认情况下，s 会收集尝试识别其 运行的集群 类型，以自动识别要从中收集报告 的节点。

  1. 您可以使用 --cluster 或 --nodes 选项手动设置 cluster 或 nodes 类型。
  2. 您还可以使用 --master 选项将 sos 程序指向远程节点以确定 集群 类型和 节点列表。因此，您不必登录到其中一个集群节点来收集 sos 报告；您可以从您的工作站来做。
  3. 您可以添加 --upload 选项，在生成后立即将 sos 报告 传输到红帽。
  4. 可以进一步提供任何有效的 sos report 选项，它们会被传递到所有 sos 报告的执行。例如 --batch 和 --clean 选项。

  sos-collector (version 4.2)
  
  This utility is used to collect sosreports from multiple nodes simultaneously.
  It uses OpenSSH's ControlPersist feature to connect to nodes and run commands remotely. If your system installation of OpenSSH is older than 5.6, please upgrade.
  
  An archive of sosreport tarballs collected from the nodes will be generated in /var/tmp/sos.o4l55n1s and may be provided to an appropriate support representative.
  
  The generated archive may contain data considered sensitive and its content should be reviewed by the originating organization before being passed to any third party.
  
  No configuration changes will be made to the system running this utility or remote systems that it connects to.

  Please enter the case id you are collecting reports for: <8-digit_case_number>
  
  sos-collector ASSUMES that SSH keys are installed on all nodes unless the
  --password option is provided.
  
  The following is a list of nodes to collect from:
      primary-rhel8
      sos-node1
      sos-node2
  
  
  Press ENTER to continue with these nodes, or press CTRL-C to quit

验证

• 验证 sos collect 命令在 /var/tmp/ 目录中创建了与命令输出中描述匹配的存档。

  [root@primary-rhel8 ~]# ls -l /var/tmp/sos-collector*
