There are many methods of disabling selinux.

 # ls -Z /
 # ls -Z /etc/

Disable SELinux Permanently

 # cat /etc/selinux/config

   SELINUX=disabled
   SELINUXTYPE=targeted
   SETLOCALDEFS=0

Where,

 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.
   SETLOCALDEFS - Check local definition changes
 SELINUXTYPE
   targeted - Only targeted network daemons are protected.
   strict - Full SELinux protection
 SETLOCALDEFS - Check local definition changes

Disable SELinux usingGrub Boot Loader

Disable SELinux Temporarily

 # cat /selinux/enforce
   1

 # echo 0 > /selinux/enforce

 # cat /selinux/enforce
   0

This will only temporarily disable selinux policies, to permanently disable selinux policies you must edit the selinux configuration file. Instead of using echo command to disable selinux, you can also use setenforce command to disable linux.

 # setenforce 0

Disable Only a Specific Service in SELinux - HTTP/Apache

 # grep httpd /etc/selinux/targeted/booleans
   httpd_builtin_scripting=1
   httpd_disable_trans=1
   httpd_enable_cgi=1
   httpd_enable_homedirs=1
   httpd_ssi_exec=1
   httpd_tty_comm=0
   httpd_unified=1

 # setsebool httpd_disable_trans 1
 # service httpd restart 

Apache or web server is a daemon where we like to avoid selinux most of the times, to disable selinux only for a particular service use the below command.
