semanage-fcontext — SELinux Policy Management file context tool
Synopsis
semanage fcontext [-h] [-n] [-N] [-S STORE] [ --add ( -t TYPE -f FTYPE -r RANGE -s SEUSER | -e EQUAL ) FILE_SPEC ) | --delete ( -t TYPE -f FTYPE | -e EQUAL ) FILE_SPEC ) | --deleteall | --extract | --list [-C] | --modify ( -t TYPE -f FTYPE -r RANGE -s SEUSER | -e EQUAL ) FILE_SPEC ) ]
Description
semanage is used to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources. semanage fcontext is used to manage the default file system labeling on an SELinux system. This command maps file paths using regular expressions to SELinux labels.
Options

- -C, --locallist
List local customizations
- -S STORE, --store STORE
Select an alternate SELinux Policy Store to manage
- -a, --add
Add a record of the specified object type
- -d, --delete
Delete a record of the specified object type
- -m, --modify
Modify a record of the specified object type
- -l, --list
List records of the specified object type
- -E, --extract
Extract customizable commands, for use within a transaction
- -D, --deleteall

- -e EQUAL, --equal EQUAL
Substitute target path with sourcepath when generating default label. This is used with fcontext. Requires source and target path arguments. The context labeling for the target subtree is made equivalent to that defined for the source.
- -f [{a,f,d,c,b,s,l,p}], --ftype [{a,f,d,c,b,s,l,p}]
File Type. This is used with fcontext. Requires a file type as shown in the mode field by ls, e.g. use 'd' to match only directories or 'f' to match only regular files. The following file type options can be passed: f (regular file),d (directory),c (character device), b (block device),s (socket),l (symbolic link),p (named pipe). If you do not specify a file type, the file type will default to "all files".
- -s SEUSER, --seuser SEUSER
SELinux user name
- -t TYPE, --type TYPE
SELinux Type for the object
- -r RANGE, --range RANGE
MLS/MCS Security Range (MLS/MCS Systems only) SELinux Range for SELinux login mapping defaults to the SELinux user record range. SELinux Range for SELinux user defaults to s0.
Example
remember to run restorecon after you set the file context Add file-context for everything under /web # semanage fcontext -a -t httpd_sys_content_t "/web(/.*)?" # restorecon -R -v /web Substitute /home1 with /home when setting file context # semanage fcontext -a -e /home /home1 # restorecon -R -v /home1 For home directories under top level directory, for example /disk6/home, execute the following commands. # semanage fcontext -a -t home_root_t "/disk6" # semanage fcontext -a -e /home /disk6/home # restorecon -R -v /disk6
