I was following this video https://www.youtube.com/watch?v=gC8sLGB8SSM&index=77&list=PL442FA2C127377F07 . I am using fedora. I am able to read a file using this code:
$fileHandle = fopen('test.txt', 'r') or die('Unable to open test.txt');
echo fread($fileHandle, filesize('test.txt'));
But when I change 'r' to 'w', it dies and prints 'Unable to open test.txt'.
To check that I have permissions to read and write to a file, I typed this on terminal, ls -l /var/www/html. It showed:
total 8
-rwxr-xr-x. 1 Hemil apache 131 Jul 6 11:09 index.php
-rw-rw-r--. 1 Hemil Hemil 12 Jul 6 11:09 test.txt
I noticed that apache did not have the permission to read and write to a file, I did this: sudo chown Hemil:apache /var/www/html. But again when i checked the permissions, it prints the same as above.
EDIT: I forgot to add that I am not on a server. I am on localhost.
EDIT: On #Nic3500 's recommendation, i add the following:
ls -al /var:

I am completely new to docker. Just trying to run WordPress within a docker instance to learn more about it.

I think I am having problems with the max children limit for php-fpm. I am trying to find something in the logs. Where can I find php-fpm.log on my server? Running phpinfo() shows this:
I cannot find anything related to php-fpm in /var/log/.
I am also trying to find the php-fpm.conf that is mentioned at https://www.php.net/manual/en/install.fpm.configuration.php. Thank you.
UPDATE 1: I found at https://github.com/rlerdorf/php7dev/issues/48 that it asks to edit /usr/local/etc/php-fpm.d/www.conf. In my case, I cannot find that file:
root#jai [/usr/local/etc]# pwd
/usr/local/etc
root#jai [/usr/local/etc]# ls -al
total 8
drwxr-xr-x. 2 root root 4096 Sep 23 2011 ./
drwxr-xr-x. 15 root root 4096 Apr 7 15:02 ../
Do I need to create it at /usr/local/etc/php-fpm.d/www.conf?
UPDATE 2: I see I have a folder called ApachePHPFPM but the file inside (default_accounts_to_fpm) is empty:
root#jai [/var/cpanel/ApachePHPFPM]# pwd
/var/cpanel/ApachePHPFPM
root#jai [/var/cpanel/ApachePHPFPM]# ls -al

-rw-r--r-- 1 root root 0 Mar 26 04:44 default_accounts_to_fpm
root#jai [/var/cpanel/ApachePHPFPM]#
UPDATE 3: My server had this file:
/usr/local/cpanel/etc/php-fpm.conf
The file contains this:
; Error log file
; Default Value: /var/log/php-fpm.log
error_log = /usr/local/cpanel/logs/php-fpm/error.log
That means that my error logs for php-fpm are located in this file: /usr/local/cpanel/logs/php-fpm/error.log.
I navigated to /usr/local/cpanel/logs/php-fpm/ but I could not find error.log:
root#jai [/usr/local/cpanel/etc]# cd /usr/local/cpanel/logs/php-fpm/
root#jai [/usr/local/cpanel/logs/php-fpm]# ls -al

I see the error log files there:

in my themes folder everything is with equals permissions but I can't access them all. For example
NOT VISIBLE - http://www.aniabuchi.com/wp-content/themes/impreza/us-logo.png
VISIBLE - http://www.aniabuchi.com/wp-content/themes/impreza/screenshot.png
The theme itself has activeted, but when I've try to active the plugins it say also "Please adjust file permissions to allow plugins installation".
This is my second wordpress installation and the only difference I've made is to use only one wp-contents folder
/* Default value for some constants if they have not yet been set
by the host-specific config files */
if (!defined('ABSPATH'))
define('ABSPATH', '/var/www/aniabuchi/');
if (!defined('WP_CORE_UPDATE'))
define('WP_CORE_UPDATE', false);
define('DB_HOST', 'localhost');
if (!defined('WP_CONTENT_DIR') && !defined('DONT_SET_WP_CONTENT_DIR'))
define('WP_CONTENT_DIR', '/var/www/aniabuchi/wp-content');
try to make images 777 to see if you can access them.
for plugin, you should check your "wp-content/plugins" folder permission, not themes.
You need to make sure the owner assigned to the files and directories is the web server user, otherwise wordpress will fail all plugin installations or updates regardless of file/folder permissions. On ubuntu/debian it's usually www-data, and on centos/rhel/fedora it's apache.
Try this and check - it might do the trick:
# chmod 755 -R <path_to_your_webroot_folder>
# chown root:root -R <path_to_your_webroot_folder>
Here is my .htaccess content:
RewriteEngine On
RewriteRule ^([^/]*)\.html$ /mtd/index.php?page=$1 [L]
RewriteRule ^([^/]*)/([^/]*)/([^/]*)\.html$ /mtd/index.php?page=$1&destination=$2&package=$3 [L]
The following link works correctly:
http://localhost/mtd/our-company.html [Rewrite Rule 1]
The page successfully passes the $_GET values index.php?page=page-name
Yet, the following link is Showing 404 Error
http://localhost/mtd/tours/nepal/index.html [Rewrite Rule 2]
This URL should pass $_GET values like:
index.php?page=tours&destination=nepal&package=index
This was working on Windows 8.1 with XAMPP Server and Remote Server with cPanel, but after I shifted to Ubuntu (Latest) with LAMP Stack, it is no longer working.

You need correct RewriteBase and make to place this rule in /mtd/.htaccess:
RewriteEngine On
RewriteBase /mtd/
RewriteRule ^([^/]+)/([^/]+)/([^/.]+)\.html$ index.php?page=$1&destination=$2&package=$3 [L,QSA]

I have a really strange error. PHP can't read a file that do exists... Some ideas? I have not SELinux installed. I'm using fedora 17 and php 5.4.
I already try everything I know, but the problem still remains.

Fedora 16 introduced the concept of a "private tmp" /tmp and /var/tmp I would throw my 2 cents on that direction.
From the manual:
2.3.3. Services Private /tmp
A number of services managed by systemd have been modified to make use of its ability to provide them with a
private /tmp directory. Privileged services using /tmp and /var/tmp
have previously been found to be open to being interfered with by
unprivileged users, potentially leading to privilege escalation. Using
private /tmp directories for services prevents this style of exploit.
The directive added to the systemd unit files for the modified
services is:
[Service]
PrivateTmp=true
