crontab执行php脚本 - 拷贝文件操作并输出日志【按照时间作为名称】

我也是无奈，本来用python的，但是各种尝试不行啊。。。。找了很多办法，就是不执行；  改成shell，一个德性，肯定是哪配置错了！
也是时间太仓促，又不想花太多时间，想想能跑就行。  就整了个php的。。。凑合用吧。。。。还行。。

用在定时执行【crontab】任务里面
copyPicFixTime.php

<?php
$dst = date('Y-m-d', time());
$src = date('Y-m-d', strtotime('-1 day'));
copy("{$src}1.png", "{$dst}1.png");
copy("{$src}2.png", "{$dst}2.png");
copy("{$src}3.png", "{$dst}3.png");
//echo $src;
//echo $dst;
file_put_contents('/home/heyclock_run_pullcopy.log', "时间: ".date('Y-m-d H:i:s')."\t".$src."->".$dst."\r\n", FILE_APPEND);
?>

配置定时执行：
  crontab -e
    
每天凌晨12点1分执行..

# Edit this file to introduce tasks to be run by cron.
#
# Each task to run has to be defined through a single line
# indicating with different fields when the task will be run
# and what command to run for the task
#
# To define the time you can provide concrete values for
# minute (m), hour (h), day of month (dom), month (mon),
# and day of week (dow) or use '*' in these fields (for 'any').#
# Notice that tasks will be started based on the cron's system
# daemon's notion of time and timezones.
#
# Output of the crontab jobs (including errors) is sent through
# email to the user the crontab file belongs to (unless redirected).
#
# For example, you can run a backup of all your user accounts
# at 5 a.m every week with:
# 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/
#
# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
#* * * * * sleep 10; . /etc/profile;/bin/sh /opt/tomcat7_heyclock/webapps/examples/copyPicFixTime.sh
1 0 * * * php /opt/tomcat7_heyclock/webapps/examples/copyPicFixTime.php

问题来了：我今天早上起来，打开客户端，查看了一下，卧槽，图片不显示。。。 看来我按照时间获取图片失败了，那肯定就是后台服务没跑起来。   来试了下，原来脚本的里面的代码也得写成绝对路径才行。。。。【我原本想的是脚本搁在哪个目录，就默认是当前目录就可以。。其实不然； 之前说是配置crontab的时候需要绝对路径，现在看来脚本里面也需要注意】

<?php
$dst = date('Y-m-d', time());
$src = date('Y-m-d', strtotime('-1 day'));
copy("/opt/tomcat7_heyclock/webapps/examples/"."{$src}1.png", "/opt/tomcat7_heyclock/webapps/examples/"."{$dst}1.png");
copy("/opt/tomcat7_heyclock/webapps/examples/"."{$src}2.png", "/opt/tomcat7_heyclock/webapps/examples/"."{$dst}2.png");
copy("/opt/tomcat7_heyclock/webapps/examples/"."{$src}3.png", "/opt/tomcat7_heyclock/webapps/examples/"."{$dst}3.png");
//echo $src;
//echo $dst;
file_put_contents('/home/heyclock_run_pullcopy.log', "时间: ".date('Y-m-d H:i:s')."\t".$src."->".$dst."\r\n", FILE_APPEND);
?>
