How to disable Selinux

The contents of my /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX=permissive
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
 
 
$ selinuxenabled && echo enabled || echo disabled enabled 

$ sestatus

installed Xdebug on a Fedora 17 OS

I installed Xdebug on a Fedora 17 OS in order to use it with netbeans 7.3.1 It took me some time so I share with you how did I managed to have it working:
Install Xdebug:
sudo yum install php-pecl-xdebug
Add this lines to php.ini at the end of the file:
sudo vi /etc/php.ini
zend_extension=/usr/lib64/php/modules/xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=127.0.0.1
xdebug.remote_port=9000

Add the same lines to xdebug.ini file:
sudo vi /etc/php-zts.d/xdebug.ini
xdebug.remote_enable=1 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000
Allow port for Xdebug
sudo semanage port -a -t http_port_t -p tcp 9000
Now find your netbeans.conf file in your system:
sudo find / -name netbeans.conf
Now, open up the file and add the text "-J-Dorg.netbeans.modules.php.dbgp.level=400" in netbeans_default_options so that the line looks somewhat like this:
netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Dsun.awt.disableMixing=true -J-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes -J-Dorg.netbeans.modules.php.dbgp.level=400"
Restart both NetBeans IDE and apache:
sudo service httpd restart
if not working then use

SQLSTATE[HY000]: General error: 1 Can't create/write to file '/tmp

You messed up with /tmp permissions. To fix:
chown root:root /tmp (root:root is mysql username and password which you used)
chmod 1777 /tmp 
/etc/init.d/mysqld restart (mysqld service restart)

X-Debug in php 5.4.17


I installed Xdebug on a Fedora 17 OS in order to use it with netbeans 7.3.1 It took me some time so I share with you how did I managed to have it working:

Install Xdebug:

sudo yum install php-pecl-xdebug

Add this lines to php.ini at the end of the file:

sudo vi /etc/php.ini

zend_extension=/usr/lib64/php/modules/xdebug.so

xdebug.remote_enable=1

xdebug.remote_handler=dbgp

xdebug.remote_mode=req

xdebug.remote_host=127.0.0.1

xdebug.remote_port=9000

Add the same lines to xdebug.ini file:

sudo vi /etc/php-zts.d/xdebug.ini


xdebug.remote_enable=1 xdebug.remote_handler=dbgp xdebug.remote_mode=req xdebug.remote_host=127.0.0.1 xdebug.remote_port=9000

Allow port for Xdebug

sudo semanage port -a -t http_port_t -p tcp 9000

Now find your netbeans.conf file in your system:

sudo find / -name netbeans.conf


Now, open up the file and add the text "-J-Dorg.netbeans.modules.php.dbgp.level=400" in netbeans_default_options so that the line looks somewhat like this:


netbeans_default_options="-J-client -J-Xss2m -J-Xms32m -J-XX:PermSize=32m -J-Dnetbeans.logger.console=true -J-ea -J-Dapple.laf.useScreenMenuBar=true -J-Dapple.awt.graphics.UseQuartz=true -J-Dsun.java2d.noddraw=true -J-Dsun.zip.disableMemoryMapping=true -J-Dsun.awt.disableMixing=true -J-Dnetbeans.extbrowser.manual_chrome_plugin_install=yes -J-Dorg.netbeans.modules.php.dbgp.level=400"


Restart both NetBeans IDE and apache:

sudo service httpd restart

if not working then use

xdebug.remote_host=127.0.0.1 to ip address of computer
