1. 环境
/usr/local/apache/htdocs/ (待检索的文件在该目录下)
/usr/local/apache/temp/ (作为中转的文件夹)
/usr/local/apache/cgi-bin/
2. 将gcc search.c产生的a.out放置在/usr/local/apache/cgi-bin/中,权限设置为nobody可以执行。
3. chown -R nobody.nobody /usr/local/apache/temp
4. 在/etc/cron.daily中增加一个文件deletetemp 权限为555
rm -f /usr/local/apache/temp/*
5. 在/etc/cron.hourly中增加一个文件myupdate 权限为555
updatedb -U /usr/local/apache/htdocs
6. 删除/etc/cron.daily中的一个文件slocate.cron
