Periodically generate logs with logrotate and delete them periodically for all logs on the system

1 For example we want to cut Nginx log, first we enter/etc/logrotate.d/this directory, and then build nginx this file

VI Nginx

/data/wwwlogs/*nginx.log {# #日志所在的目录dailyrotate 5missingokdateextcompressnotifemptysharedscriptspostrotate [-E/ Var/run/nginx.pid] && kill-usr1 ' cat/var/run/nginx.pid ' Endscript}

Parameter description:

Monthly specify a dump cycle of monthly

Daily Specify a dump cycle of daily

Weekly specify the dump cycle as weekly

Rotate count Specifies the number of times the log file was dumped before it was deleted, 0 means no backup, 5 means 5 backups reserved (this means a 5-day backup is reserved)

Compress post-dump log after gzip compression

Copytruncate The log file is emptied after the current log file is copied, instead of renaming the current log file to create a new

Notifempty if it's an empty file, don't dump it.

Dateext the log file after switching appends the date of the previous dash and YYYYMMDD format.

[-e/var/run/nginx.pid] && kill-usr1 ' cat/var/run/nginx.pid ' endscript This parameter is for Nginx to regenerate the log

2. Restart the SYSLOGD service

Service Rsyslog Restart

3 Testing

#强制执行某个日志的切换, Nginx is the filename of the file under/ETC/LOGROTATE.D

Logrotate-f/etc/logrotate.d/nginx

#如果在存放日志的目录下发现了切换的日志文件, the switch is successful
