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
mountcommand. For example, if the ISO file is calledexample.isoand is located in the/mntdirectory, you can use the following command:mount -o loop /mnt/example.iso /mnt/iso
This will create a new directory called
isoin the/mntdirectory, which will contain the contents of the ISO image. - Next, you need to set the correct SELinux context for the
isodirectory. You can do this using thechconcommand:chcon -t httpd_sys_content_t /mnt/iso
This will set the
httpd_sys_content_tcontext for theisodirectory, which will allow Apache to serve its contents. - Finally, you need to allow Apache to access the
isodirectory. You can do this by creating a new SELinux policy module using theaudit2allowcommand. First, you need to generate an audit log by attempting to access theisodirectory using Apache:audit2allow -w -a
This will generate an audit log in
/var/log/audit/audit.log. Look for theavc: deniedmessages related to theisodirectory and note theallowstatements that are suggested in the log. - Create a new SELinux policy module using the suggested
allowstatements 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
isodirectory.
After completing these steps, you should be able to access the contents of the loopback mounted ISO image via Apache.
