默认使用 05_logging.cfg
中的日志配置。Red Hat Enterprise Linux(RHEL)文件的默认内容如下:
## This yaml formatted config file handles setting ## logger information. The values that are necessary to be set ## are seen at the bottom. The top '_log' are only used to remove ## redundancy in a syslog and fallback-to-file case. ## ## The 'log_cfgs' entry defines a list of logger configs ## Each entry in the list is tried, and the first one that ## works is used. If a log_cfg list entry is an array, it will ## be joined with '\n'. _log: - &log_base | [loggers] keys=root,cloudinit [handlers] keys=consoleHandler,cloudLogHandler [formatters] keys=simpleFormatter,arg0Formatter [logger_root] level=DEBUG handlers=consoleHandler,cloudLogHandler [logger_cloudinit] level=DEBUG qualname=cloudinit handlers= propagate=1 [handler_consoleHandler] class=StreamHandler level=WARNING formatter=arg0Formatter args=(sys.stderr,) [formatter_arg0Formatter] format=%(asctime)s - %(filename)s[%(levelname)s]: %(message)s [formatter_simpleFormatter] format=[CLOUDINIT] %(filename)s[%(levelname)s]: %(message)s - &log_file | [handler_cloudLogHandler] class=FileHandler level=DEBUG formatter=arg0Formatter args=('/var/log/cloud-init.log',) - &log_syslog | [handler_cloudLogHandler] class=handlers.SysLogHandler level=DEBUG formatter=simpleFormatter args=("/dev/log", handlers.SysLogHandler.LOG_USER) log_cfgs: # Array entries in this list will be joined into a string # that defines the configuration. # # If you want logs to go to syslog, uncomment the following line. # - [ *log_base, *log_syslog ] # # The default behavior is to just log to a file. # This mechanism that does not depend on a system service to operate. - [ *log_base, *log_file ] # A file path can also be used. # - /etc/log.conf # This tells cloud-init to redirect its stdout and stderr to # 'tee -a /var/log/cloud-init-output.log' so the user can see output # there without needing to look on the console. output: {all: '| tee -a /var/log/cloud-init-output.log'}
