linux - php unwritable for the file under /etc -



linux - php unwritable for the file under /etc -

i want write script config centos network config file!but had no permission write these config files(/etc/sysconfig/network-script/ifcfg-eth0)!even gave whole etc dir 777 permission.but didn't work!

chmod -r 777 /etc

the php scirpt test file readable or writeable:

$file = "/etc/sysconfig/network-scripts/ifcfg-eth0"; $link = fopen($file,"r+"); echo $file,is_readable($file)?"yes":"no<br>"; echo $file,is_writable($file)?"yes":"no<br>";

the result unreadable , unwritable:

/etc/sysconfig/network-scripts/ifcfg-eth0yes /etc/sysconfig/network-scripts/ifcfg-eth0no

who can give me suggesion!

your file info may cached. seek running script work. (see the php documentation more info.)

<?php clearstatcache(); ?>

if doesn't work, you'll need tell result of stat /etc/sysconfig/network-scripts/ifcfg-eth0 in shell.

never run chmod -r 777 /etc. @ best, may cause problems programs expecting permissions. in worst case scenario, entire scheme compromised hacker, , may have been. consider using fresh installation of operating scheme rather continuing utilize server.
