Enter the command line mode first. Linux as the server generally enters the command line mode by default. Of course, our management server is generally connected to the server remotely through tools such as putty or xshell. Type in the command line:
crontab -e
After that, a file will be opened, and it is in the non-editing state, which is the editing interface of vi. You can edit the content by typing i on the keyboard and entering the editing mode. If you want to improve efficiency, using php to execute local php files is the best choice, for example:
00 */2 * * * /user/local/php/bin/php /home/wwwroot/yii(项目根目录) test/index
This statement can be executed every 2 hours and 0 minutes, through the Linux internal PHP environment to execute test / index. Note that here is not executed through the url access, through the server environment, but directly executed, because the server environment is bypassed, So of course the efficiency is much higher.
Ok, click the Esc key on the keyboard, enter ": wq" and press Enter. This saves the scheduled task, and you can also see the prompt to create a new scheduled task on the screen.
crontab time format:
分 时 日 月 周
第1列表示分钟1～59 每分钟用或者 */1表示，/n表示每n分钟，例如*/8就是每8分钟的意思，下面也是类推
