*. Download file: http://www.zend.com/en/products/guard/downloads

This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.2.0, Copyright (c) 1998-2009 Zend Technologies
With Zend Optimizer v3.3.9, Copyright (c) 1998-2009, by Zend Technologies error handling
First of all, I am not so lucky. When I restart Apache, the error is as follows:

Stopping XAMPP for Linux 1.7.1...
XAMPP: Stopping Apache with SSL...
Failed loading/opt/lampp/lib/ZendOptimizer. so:/opt/lampp/lib/ZendOptimizer. so: cannot restore segment prot after reloc: Permission denied

XAMPP stopped.

XAMPP for Linux started. solution:
Edit/etc/selinux/config and find the following link:

# This file controls the state of SELinux on the system.
# SELINUX = can take one of these three values:
# Enforcing-SELinux security policy is enforced.
# Permissive-SELinux prints warnings instead of enforcing.
# Disabled-SELinux is fully disabled.
SELINUX = enforcing comment out SELINUX = enforcing: # SELINUX = enforcing, and then add a new line:

SELINUX = disabled save, disable.
......

Edit/etc/sysconfig/selinux and find:

# This file controls the state of SELinux on the system.
# SELINUX = can take one of these three values:
# Enforcing-SELinux security policy is enforced.
# Permissive-SELinux prints warnings instead of enforcing.
# Disabled-SELinux is fully disabled.
SELINUX = enforcing if SELINUX is already set to SELINUX = disabled, you do not need to change it. Otherwise, you need to comment out SELINUX = enforcing and add a new line:

SELINUX = disabled: Save and exit.
-----------------------------
If the problem persists, run the following command after you make sure to execute the above operation.

Chcon-t texrel_shlib_t/opt/lampp/lib/ZendOptimizer. so can be solved.

Then try restarting the server and enter/opt/lampp restart. The above error should not be returned.
