Codeigniter cron工作不起作用

Question

I have a cron job like this:

/usr/bin/php /var/www/website/public_html/index.php className methodName

If I run it in terminal it runs, but outputs nothing. If I pass a wrong method name it runs successfully. If I pass wrong class name it outputs a website 404 error.

I also have a routing which adds "en" into url, for example

http://www.website.com/en/home/index

could this be the problem?

my settings of config.php are:

$config['uri_protocol'] = 'AUTO';
$config['index_page'] = '';

Answer 1

the steps to prepare CodeIgniter 2.x for cron-jobs via CLI (command line interface):

1st: create a copy of your root index.php file and save it in your root as cli.php

2nd: in your cli.php replace <?php with this code:

#!/usr/local/bin/php
<?php

/* override normal limitations */
set_time_limit(0);
ini_set('memory_limit', '256M');

/* deny direct call from web browser */
if (isset($_SERVER['REMOTE_ADDR'])) die('Permission denied.');

/* constants */
define('CMD', 1);

/* manually set the URI path based on command line arguments... */
unset($argv[0]); /* except the first one */
$_SERVER['QUERY_STRING'] =  $_SERVER['PATH_INFO'] = $_SERVER['REQUEST_URI'] = '/' . implode('/', $argv) . '/';

3rd: execute your cron job like this:

/usr/bin/php /var/www/website/public_html/cli.php controller method

where /var/www/website/public_html/ is your server's home directory, the location of your index.php and cli.php.

notes:

for CI 3.0 you find the necessary information here

database: you'll need to provide your db config settings in your controller method, as the cron job just executes the controller's method. So it doesn't know anything about any database settings!

$config['hostname'] = "localhost";
$config['username'] = "username_admin";
$config['password'] = "password";
//etc..

$this->db  = $this->load->database($config, TRUE);

debug: just add a link in your html to run your controller's method like: index.php/controller/method (remove that once you website is live)
