You need to set the appender of the logger:
log4j.properties file:

log4j.logger.log_name=debug, F

log4j.appender.F=org.apache.log4j.DailyRollingFileAppender
log4j.appender.F.File=full_file_path/file.log
log4j.appender.F.DatePattern='.'yyyy-MM-dd

Every day the old file will be renamed according to the pattern, Look at the API for the class: org.apache.log4j.DailyRollingFileAppender and for the Logger class.
