Php --SourceGuardian

PHP script /home/adzworkc/ClixScript_PHP_DOCS/classes/class.vars.php is protected by SourceGuardian and requires the SourceGuardian loader ixed.5.3.lin. The SourceGuardian loader has not been installed, or is not installed correctly. Please find the required loader within SourceGuardian installation directory or visit the SourceGuardian php encoder site to download it.

root@server [~]# /scripts/phpextensionmgr list
Available Extensions:
EAccelerator
IonCubeLoader
Zendopt
Xcache
SourceGuardian
PHPSuHosin

root@server [~]# /scripts/phpextensionmgr install SourceGuardian

===

If the issue still persist
check the php.ini

root@server [/home]# php -i | grep ini

We can see

===

Configuration File (php.ini) Path => /usr/local/lib
Loaded Configuration File => /usr/local/lib/php.ini
Scan this dir for additional .ini files => (none)
additional .ini files parsed => (none)

===

Now open

root@server [/home]# vi /usr/local/lib/php.ini

and check the extention file

===
root@server [/home]# cd /usr/local/lib/php/extensions/no-debug-non-zts-20060613

root@server [/usr/local/lib/php/extensions/no-debug-non-zts-20060613]# ll

drwxr-xr-x 2 root root 4096 Jan 21 20:51 ./
drwxr-xr-x. 4 root root 4096 Dec 29 12:05 ../
-rw-r–r– 1 root root 79448 Jan 21 20:50 ixed.5.2.lin
-rwxr-xr-x 1 root root 544910 Jan 4 19:03 pdo.a*
-rwxr-xr-x 1 root root 275820 Jan 4 19:03 pdo_mysql.a*

===

Now we can see that the version is ixed.5.2.lin but we need ixed.5.3.lin.

So downlaod file from

http://www.sourceguardian.com/loaders.html

and upload it to this folder
root@server [/usr/local/lib/php/extensions/no-debug-non-zts-20060613]#

Then open

vi /usr/local/lib/php.ini
shift +g
we can sse that

===

extension=”ixed.5.2.lin”
zend_extension=”/usr/local/Zend/lib/Optimizer-3.3.9/php-5.2.x/ZendOptimizer.so”

===

Change the version here manually.

Modifying your PHP Handler Configuration

What’s my current configuration?

# /usr/local/cpanel/bin/rebuild_phpconf --current
Available handlers: suphp dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: none
PHP5 SAPI: suphp
SUEXEC: enabled

Let’s say I wanted to switch to DSO, keeping PHP4 disabled, and SuExec enabled:
# /usr/local/cpanel/bin/rebuild_phpconf 5 none fcgi 1

For reference, the usage details:

Usage: /usr/local/cpanel/bin/rebuild_phpconf [--dryrun] [--no-restart] [--no-htaccess] [--current|--available]
--dryrun : Only display the changes that would be made
--no-restart : Don't restart Apache after updating the php.conf link
--no-htaccess : Don't update user configurable PHP mime mapping.
--current : Show current settings
--available : Show available handlers and PHP SAPIs
: Version of PHP to set as default handler for .php files
<php# handler="">: Type of Apache module to use in serving PHP requests
: enabled, disabled, 1 or 0

Fatal error: Allowed memory size of xxxxxxxx bytes exhausted If deactivating plugins doesn’t work try one of these methods for increasing the amount of memory a PHP script may consume

1. If you have access to your PHP.ini file, change the line in PHP.ini
If your line shows 32M try 64M:
memory_limit = 64M ; Maximum amount of memory a script may consume (64MB)

2. If you don’t have access to PHP.ini try adding this to an .htaccess file:
php_value memory_limit 64M

3. Try adding this line to your wp-config.php file:
Increasing memory allocated to PHP
define(‘WP_MEMORY_LIMIT’, ’64M’);

How to clear eximstats db

If the size of your eximstats database is getting large, you can do the following steps to clear it.

Login to mysql

mysql

mysql> use eximstats
mysql> delete from sends;
mysql> delete from smtp;
mysql> delete from failures;
mysql> delete from defers;

Load due to a particular domain in the server

Whenever the load in the server increases due to a particular user in the server. Check the following:

Find the domain owned by the user:

grep username /etc/userdomains

use the following command after you get the domain name:

less /usr/local/apache/domlogs/domain.com | awk ‘{print $1}’ | sort | uniq -c | sort -n

This will give the ip and number of connections in the descending order. For example:

 13832 65.52.110.145
 19112 66.249.68.183
208262 157.55.16.55

In the above case we can see too many connections from those ips. This is surely abnormal. Immediately block such ips in the server using csf

csf -d IP

[if not present use iptables].

SAMPLE PHP SCRIPT FOR SENDING MAILS

<?php

$Subject=”Trying to send”;
$Sender=”testing@betsexperts.com”;
$SendTo=”testmail4us@gmail.com”;
$Message2=”Testing mail”;

if(mail($SendTo, $Subject, $Message2, “From: $Sender”)){
print” Sent to: $SendTo … Sender: $Sender”;
}else{
print” Not sent to: $SendTo … Sender: $Sender”;
}

?>

Tips to remember:

Step 1:
Create a test.php inside public_html folder
For example —> /home/public_html/test.php
Step2:
Copy the above script and paste inside test.php (remember to change the ownership of test.php)
Step3:
run the url
For example—> if you are creating test.php in your website http://example.com
Run the url as http://example.com/test.php
The mail will automatically send as php
