schedule

有个ubuntu服务器，跑着apache， PHP7， Laravel，supervisor。 apache和supervisor都是www-data用户。 平时管理员ssh登上去用的都是devuser用户。 今天发现Laravel日志异常了，连着几天都是只有短短一行日志记录。 新的日志都写不进去。chown 改成 www-data 后日志还是写不进去，见了鬼了。 后来尝试重启 apache， supervisor， PHP7 ，然后重命名掉今天的日志文件，发现新日志终于有了。是正常的 www-data 用户的文件。 怀疑为什么会有 devuser 的日志文件产生： 有人用 devuser 身份 SSH 登进来搞事情。 有什么软件是以 devuser 身份执行了。 我们检查了 apache， supervisor， PHP配置文件， 都是 www-data。百思不得其解。 最后排查到定时任务，才想起来我们使用了 crontab 来重复触发 artisan schedule:run 来执行定时任务。 由于我们使用了 devuser 来配置的 crontab -e，所以执行身份肯定是 devuser。 最后我们将 schedule:run 命令写入了 /etc/crontab 里面，指明用 www-data 执行。 天下太平了。 来源： oschina 链接： https://my

The problem is that, if the server has been stopped during 5 hours, the job will be launched 5 times, but in all of the executions "new Date()" will be
