Nginx 日志切割

把 Nginx 的访问日志每天切割一次，保留30天：

[root@localhost ~]$ cat /data/script/cut_nginx_log.sh 
#!/bin/bash

today=`date +%Y%m%d`
logDir='/usr/local/nginx/logs'

mv $logDir/access.log $logDir/access_${today}.log
kill -USR1 `cat $logDir/nginx.pid`
find $logDir -maxdepth 1 -mtime +30 -type f -name "access*" -exec rm -rf {} \; &> /dev/null

[root@localhost ~]$ crontab -l
59 23 * * * sh /data/script/cut_nginx_log.sh > /dev/null 2>&1
