initialize_logger() public

If the RAILS_DEFAULT_LOGGER constant is already set, this initialization routine does nothing. If the constant is not set, and Configuration#logger is not nil, this also does nothing. Otherwise, a new logger instance is created at Configuration#log_path, with a default log level of Configuration#log_level.

If the log could not be created, the log will be set to output to STDERR, with a log level of WARN.
