# php -m
Failed loading /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so:  /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so: cannot restore segment prot after reloc: Permission denied

Нашел три вариант решения проблемы:
1) Disable SELinux by editing /etc/selinux/config and setting SELINUX=disabled' there.
2) If you want SELinux enabled, you can remove SELinux protection from httpd by using system-config-securitylevel tool
3) If you want SELinux protection on httpd, use this to enable loading Zend modules: chcon -t httpd_modules_t `find /usr/local/Zend/lib -name \*.so`

Первые два работают но меня они не устраивают.
Третий способ не срабатывает.

#  ls -Z /usr/local/Zend/lib/*.so
-rwxr-xr-x  root root system_u:object_r:httpd_modules_t /usr/local/Zend/lib/ZendExtensionManager.so
-rwxr-xr-x  root root system_u:object_r:httpd_modules_t /usr/local/Zend/lib/ZendExtensionManager_TS.so

Какие есть предложения?

Allowing Access
    If you trust /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so
    to run correctly, you can change the file context to textrel_shlib_t. "chcon
    -t textrel_shlib_t
    /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so"

    The following command will allow this access:
    chcon -t textrel_shlib_t /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so

# chcon -t textrel_shlib_t /usr/local/Zend/lib/Optimizer-3.3.3/php-5.2.x/ZendOptimizer.so

# php -m

Модуль подгрузился но в phpinfo его не видно...
