Linux timed php execution

1. Using Crond Service

　　

Crontab-e #编辑任务列表crontab-L #展示任务列表26 * * */usr/local/php70/bin/php-q/data/www/crm/savenum.php

Service Crond Restart (or reload) #重启更新

　　

User Timed Task instance:

01 * * * * cmd #每小时的01分钟执行02 04 * * * cmd #每天4点的02分钟执行22 14 * * 00 cmd #每周日的14点22分执行42 04 01 * * cmd #每月1日的4点42分执行 Minute hour day-of-month month-of-year day-of-week commands

Tips:

1. CMD is the command or script to execute, for example:/bin/sh/server/scripts/chensiqi.sh

2. There must be a space between each column. Can I have more than one space? My own practice ==> by my own test has a number of spaces can also be executed!!
