    Can't write to file on localhost

    Morning, Having problems with write to file on localhost.

    Just wanted to run a simple test using php file put contents or even fwrite and it's not working.

    Even made the folder and it's contents 777 for testing and ensured I am the owner of the folder and contents

    Any ideas please?

    It's definitely SELinux, I'm a total novis at this and disable it to check and access to write to file works. I then put the setting back to 'enforce'.

    Now what?

    Thanks

    edit /etc/selinux/config
    SELINUX=disabled
    SELINUXTYPE=disabled

    reboot
    the edit /etc/default/grub
    GRUB_CMDLINE_LINUX="rhgb quiet selinux=0"
    grub2-mkconfig -o /boot/grub2/grub.cfg

    reboot.
    no more problems.

    selinux was created for the US military to have "secure and separate user spaces", like in the old mainframes.
    we don't need that in a home computer, besides nobody knows if the NSA is spying through it.

    I ended up installing trouble shooter and it then provided some help and bash commands to allow access.

    I have thought the same about selinux and it's necessity on a home computer but as it's working (for now) I'll leave it as is

    Cheers for the reply

    Much appreciated

    If the top level file has a constraint, then the directory under that top level dir also has a constraint.

    I have a /scratch (its in root and it is owned by root)
    For my /scratch/Development, I had to sudo chmod 1777 /scratch The 1777 makes the /scratch rwx for anyone, with no rwx restriction.

    Re: Can't write to file on localhost

    When debugging selinux issues it is sometimes useful to switch from "enforcing" to "permissive" status.
    This will throw a warning message about the detected issue, but will not block the activity. Usually gives you enough info to correct the issue and then return to "enforcing" security levels.

    I do not support the idea that personal security is less important than business/government security. ( if NSA wants to look at you they don't need any help from selinux )

    Re: Can't write to file on localhost

    Moved back to Ubuntu on my home machine but still using Fedora 27 (that works fine) at the office . . . after four fresh installs and SElinux still not playing nice I'm convinced that there is something wrong with version 28.

    Plus, on regular basis Fedora freezes half way through boot up. I have wasted so much time on this that I can't delay any longer.

    Thank you everyone for your responses, much appreciated.
