基于swoole的定时任务,精确到秒级
①必须安装swoole扩展,且扩展版本大于4.0
②执行crontab.sql文件,在cron添加想要执行的定时任务,格式如下:
0 1 2 3 4 5
* * * * * *
- - - - - -
| | | | | |
| | | | | +----- day of week (0 - 6) (Sunday=0)
| | | | +----- month (1 - 12)
| | | +------- day of month (1 - 31)
| | +--------- hour (0 - 23)
| +----------- min (0 - 59)
+------------- sec (0-59)
③运行center.php即可
