seo说要备份文件，然后自己搞不定，每天一份文件。写了个shell，加了个crontab -e任务。每天执行一次。
crontab:
59 23 * * * /root/sh/dumpApacheLog
shell:
#!/bin/sh
today=$(date +%Y%m%d)
newAccessLog="/usr/local/httpd/logs/"$today"access_log"
newErrorLog="/usr/local/httpd/logs/"$today"error_log"
mv /usr/local/httpd/logs/access_log $newAccessLog
mv /usr/local/httpd/logs/error_log $newErrorLog
touch /usr/local/httpd/logs/access_log
touch /usr/local/httpd/logs/error_log
chmod 777 /usr/local/httpd/logs/error_log
chmod 777 /usr/local/httpd/logs/access_log
