7.11. 查看 Master 和节点日志
OpenShift Container Platform 使用 systemd-journald.service 作为节点和名为 master-logs 的脚本，为 master 收集调试的日志消息。
注意
web 控制台中显示的行的数量在 5000 中被硬编码，且无法更改。要查看整个日志，可使用 CLI。
日志记录根据 Kubernetes 日志记录惯例使用五个日志消息，如下所示：
| 选项 | 描述 |
|---|---|
| 0 | 仅限错误和警告 |
| 2 | 普通信息 |
| 4 | 调试级别信息 |
| 6 | API 级调试信息（请求/响应） |
| 8 | 正文级别 API 调试信息 |
您可以根据需要 更改独立于 master 或节点的日志级别。
查看节点日志
要查看节点系统的日志，请运行以下命令：
# journalctl -r -u <journal_name>
使用 -r 选项显示最新的条目。
查看 master 日志
要查看 master 组件的日志，请运行以下命令：
# /usr/local/bin/master-logs <component> <container>
例如：
# /usr/local/bin/master-logs controllers controllers # /usr/local/bin/master-logs api api # /usr/local/bin/master-logs etcd etcd
将 master 日志重定向到文件
要将 master 日志的输出重定向到文件，请运行以下命令：
master-logs api api 2> file
7.11.1. 配置日志记录级别
您可以通过在 master 或 /etc/sysconfig/atomic-openshift-node 文件中的 /etc/origin/master/master.env 文件中设置 DEBUG_LOGLEVEL 选项来控制哪些 INFO 信息。将日志配置为收集所有信息可能会导致大型日志被解释，并可能会占用过量空间。仅在需要调试集群时收集所有消息。
注意
不论日志配置是什么，日志中会出现带有 FATAL、ERROR、WARNING 和一些 INFO 严重性的消息。
更改日志记录级别：
- 编辑 master 或 /etc/sysconfig/atomic-openshift-node 文件的 /etc/origin/master/master.env 文件。
在
DEBUG_LOGLEVEL字段中，输入 Log Level Options 表中的值。例如：
DEBUG_LOGLEVEL=4
- 根据需要重启 master 或节点主机。请参阅重启 OpenShift Container Platform 服务。
重启后，所有新日志消息均符合新设置。旧的消息不会更改。
注意
可以使用标准集群安装过程来设置默认日志级别。如需更多信息，请参阅 集群变量。
以下示例是不同日志级别重定向的主日志文件的摘录。已从这些示例中删除系统信息。
