Install xcache

July 12, 2016 The Geek Decoder No Comments Apache, PHP

CentOS 6

# yum install php-xcache xcache-admin

Debian/Ubuntu/Linux Mint


# apt-get install php5-xcache

Configure

RHEL/CentOS/Fedora


# nano /etc/php.d/xcache.ini

Debian/Ubuntu/Linux Mint


# nano /etc/php5/conf.d/xcache.ini

OR

# nano /etc/php5/mods-available/xcache.ini

Verify

# php -v

Enabling XCache Admin Panel for PHP

By default the admin panel is protected with http-auth and in disabled state. To set user/password open the Xcache.ini file. But, first you have to create md5 password using following command. (Where typeyourpassword is your password).


# echo -n "typeyourpassword" | md5sum

Sample Output


ae9ac3f19ae3990b2c99701061c5d8c2

Now open Xcache.ini file add the generated md5 password. See the following example, add your own password md5 string.


[xcache.admin]
xcache.admin.enable_auth = On
; Configure this to use admin pages
xcache.admin.user = "mOo"
; xcache.admin.pass = md5($your_password)
xcache.admin.pass = "ae9ac3f19ae3990b2c99701061c5d8c2"

The simplest way to do so is copying the whole directory xcache (admin was in older release) to your web root directory (i.e. /var/www/html or /var/www).


# cp -a /usr/share/xcache/ /var/www/html/

OR


# cp -a /usr/share/xcache/htdocs /var/www/xcache

OR


cp -a /usr/share/xcache/admin/ /var/www/ (older release)

Now call it from your browser, a http-auth login prompt window will pop-up. Enter your user/pass in, and it’s done.

http://localhost/xcache OR http://localhost/admin (older release)

White Screen of Death (WSOD) in php page

August 22, 2015 The Geek Decoder No Comments PHP

You must turn on PHP error reporting. To do this, you should change the setting in your php.ini config file. Temporarily insert the following lines in your index.php file:


error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);

Make sure that you have inserted the code directly after the opening PHP tag. The errors should now appear directly on your screen. Alternatively, check your log files for the most recent errors.
