Security-Enhanced Linux secures the httpd processes via flexible mandatory access control.
The httpd processes execute with the httpd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.
For example:
ps -eZ | grep httpd_t
The httpd_t SELinux type can be entered via the httpd_exec_t file type.
The default entrypoint paths for the httpd_t domain are the following:
/usr/sbin/httpd(.worker)?, /usr/sbin/apache(2)?, /usr/lib/apache-ssl/.+, /usr/sbin/apache-ssl(2)?, /usr/sbin/nginx, /usr/sbin/thttpd, /usr/sbin/php-fpm, /usr/sbin/cherokee, /usr/sbin/lighttpd, /usr/sbin/apachectl, /usr/sbin/httpd.event, /usr/bin/mongrel_rails, /usr/sbin/htcacheclean
You can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux httpd policy is very flexible allowing users to setup their httpd processes in as secure a method as possible.
The following process types are defined for httpd:
httpd_t, httpd_helper_t, httpd_php_t, httpd_rotatelogs_t, httpd_suexec_t, httpd_sys_script_t, httpd_user_script_t, httpd_passwd_t, httpd_unconfined_script_t
Note: semanage permissive -a httpd_t can be used to make the process type httpd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

Policy governs the access confined processes have to these ports. SELinux httpd policy is very flexible allowing users to setup their httpd processes in as secure a method as possible.
The following port types are defined for httpd:

Default Defined Ports: tcp 80,81,443,488,8008,8009,8443,9000
The SELinux process type httpd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions.

You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux httpd policy is very flexible allowing users to setup their httpd processes in as secure a method as possible.
EQUIVALENCE DIRECTORIES
httpd policy stores data with multiple different file context types under the /var/lib/php directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv dirctory you would execute the following command:
semanage fcontext -a -e /var/lib/php /srv/php
restorecon -R -v /srv/php
httpd policy stores data with multiple different file context types under the /var/www directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv dirctory you would execute the following command:
semanage fcontext -a -e /var/www /srv/www
restorecon -R -v /srv/www
STANDARD FILE CONTEXT
SELinux defines the file context types for the httpd, if you wanted to store files with these types in a diffent paths, you need to execute the semanage command to sepecify alternate labeling and then use restorecon to put the labels on disk.
semanage fcontext -a -t httpd_var_run_t '/srv/myhttpd_content(/.*)?'
restorecon -R -v /srv/myhttpd_content
Note: SELinux often uses regular expressions to specify labels that match multiple files.
The following file types are defined for httpd:
httpd_cache_t
- Set files with the httpd_cache_t type, if you want to store the files under the /var/cache directory.
