To allow SELinux to serve the contents of a loopback mounted ISO image via Apache, you can follow these steps:
- First, mount the ISO image using the
mount
command. For example, if the ISO file is calledexample.iso
and is located in the/mnt
directory, you can use the following command:mount -o loop /mnt/example.iso /mnt/iso
This will create a new directory called
iso
in the/mnt
directory, which will contain the contents of the ISO image. - Next, you need to set the correct SELinux context for the
iso
directory. You can do this using thechcon
command:chcon -t httpd_sys_content_t /mnt/iso
This will set the
httpd_sys_content_t
context for theiso
directory, which will allow Apache to serve its contents. - Finally, you need to allow Apache to access the
iso
directory. You can do this by creating a new SELinux policy module using theaudit2allow
command. First, you need to generate an audit log by attempting to access theiso
directory using Apache:audit2allow -w -a
This will generate an audit log in
/var/log/audit/audit.log
. Look for theavc: denied
messages related to theiso
directory and note theallow
statements that are suggested in the log. - Create a new SELinux policy module using the suggested
allow
statements by running the following command:audit2allow -a -M mypol
This will create a new policy module called
mypol.pp
. - Install the new policy module by running the following command:
semodule -i mypol.pp
This will install the new policy module and allow Apache to access the
iso
directory.
After completing these steps, you should be able to access the contents of the loopback mounted ISO image via Apache.
