Reading apache error logs from php

manpreet Best Answer 3 years ago

I have apache2 logs at :/var/log/apache2/error.log which has permission:

-rw-r----- 1 root adm 127140 Mar 20 12:54 /var/log/apache2/error.log

for the sake of accessing from php I changed the ownership and group e.g

-rwxrwxrwx 1 www-data www-data 127140 Mar 20 12:54 /var/log/apache2/error.log

But still I am not able to access the logs as shown below.

test.php

php
 var_dump(exec("/usr/bin/tail -n 10 /var/log/apache2/error.log",$x),$x);
?>

output

string(0) "" array(0) { } 

My question is how to alter permission to give php process to at-least read the apache logs ? A secure/standard way to access these logs will be much appreciated .

I see following error in error.log

/usr/bin/tail: cannot open `/var/log/apache2/error.log' for reading: Permission denied
