Use logrotate to manage nginx log files

Description: If linux log files are cleared occasionally, the entire disk is filled. This is dangerous, so log management is one of the daily work of the system administrator. We can use logrotate to manage linux log files, which can implement automatic log scrolling, log archiving, and other functions.
