I have a PHP application developed and running on LAMP. I have APC installed on the server. APC is a free, open, and robust framework for caching and optimizing PHP intermediate code. The APC based caching is good for my web site, but my cron jobs and php cli scripts fail to
fetch correct data due to caching. How do I disable APC module at the command line (php-cli) under Linux or Unix like operating systems for all my cron jobs?
The bug may be fixed by applying stable APC patches. APC code is actively maintained. So try updating to the latest stable version. If you are using
php-cli,
php5-cli or
php binary file directly from your scripts try passing
-d option. This option can define and override INI entry that enables APC. The exact entry can be located using the
following grep command line syntax:
### note php.ini path may be differnt under Unix or linux ###
grep --color -i enabled /etc/php.d/php.ini |
### note php.ini path may be differnt under Unix or linux ###
grep --color -i enabled /etc/php.d/php.ini
Sample outputs:
apc.enabled=1
Use the following syntax to define an entry apc.enabled with value 0 (disable it):
/usr/bin/php -d apc.enabled=0 my.cron.php
/usr/bin/php -d apc.enabled=0 /path/to/myshelljob.php
/usr/bin/php-cli -d apc.enabled=0 /path/to/myshelljob.php |
/usr/bin/php -d apc.enabled=0 my.cron.php
/usr/bin/php -d apc.enabled=0 /path/to/myshelljob.php
/usr/bin/php-cli -d apc.enabled=0 /path/to/myshelljob.php
Or you can create a small shell script wrapper for your cron jobs under Linux or Unix like oses:
#!/bin/bash
# Purpose - Create search index file for AWS search web service for our db
# Author: nixCraft <www.cyberciti.biz>
# ------------------------------------------------------------------------
_php="/usr/bin/php"
_nice="/bin/nice"
_phpargs="-d apc.enabled=0"
_base="/opt/sysadmin/aws"
_tmp="$_base/tmp"
[[ ! -d "$_tmp/$i" ]] && /bin/mkdir "$_tmp/$i"
## Run php with APC disabled ###
$_nice -n 3 $_php $_phpargs -f $_base/php/createsearchindex.php |
#!/bin/bash
# Purpose - Create search index file for AWS search web service for our db

_base="/opt/sysadmin/aws"
_tmp="$_base/tmp"
[[ ! -d "$_tmp/$i" ]] && /bin/mkdir "$_tmp/$i"## Run php with APC disabled ###
$_nice -n 3 $_php $_phpargs -f $_base/php/createsearchindex.php
