在 crontab
文件中,字段是:
In a crontab
file, the fields are:
所以:
10 * * * * blah
表示每小时过去 10 分钟执行 blah
.
means execute blah
at 10 minutes past every hour.
如果您想每五分钟使用一次:
If you want every five minutes, use either:
*/5 * * * * blah
表示每分钟但仅每五分之一,或:
meaning every minute but only every fifth one, or:
0,5,10,15,20,25,30,35,40,45,50,55 * * * * blah
对于不理解 */x
符号的旧 cron
可执行文件.
for older cron
executables that don't understand the */x
notation.
如果之后它仍然似乎不起作用,请将命令更改为:
If it still seems to be not working after that, change the command to something like:
date >>/tmp/debug_cron_pax.txt
并监视该文件以确保每五分钟写入一次内容.如果是这样,则说明您的 PHP 脚本有问题.如果没有,则您的 cron
守护进程有问题.
and monitor that file to ensure something's being written every five minutes. If so, there's something wrong with your PHP scripts. If not, there's something wrong with your cron
daemon.
