Nginx + PHP maximum output limit

6

I have php 5.5 (fpm) and nginx 1.10 installed (gzip configured to 1). Running on ubuntu.

When I am "echoing" a large output (over 2 mb), it stops abruptly at around 520 kb.

But same program when I run on php-cli, it has no problem "echoing" the whole thing onto the terminal.

Also downloading mysql dumps through adminer gets stopped in the half way. I mean incomplete files get downloaded (if the correct total output is bigger in couple of MBs).

How to fix this?

There is nothing wrong with my program. Even a simple long enough for loop spurting out echo "hello world" gets stopped at specific byte limit.

I am not sure if this issue is caused from nginx side or php side.

Apache executes HTML, but not PHP; PHP CLI works

5

I am running php 5.3.3 on rhel 6.2 with Apache 2.2.15 and am failing to get PHP code interpreted by Apache.

There are no errors (in the system log, httpd/error_log, or php_errors.log) - I have enabled error reporting in php.ini:

error_reporting = E_ALL & ~E_DEPRECATED
display_errors = On
log_errors = On
error_log = /var/log/php_errors.log

Yet, when i view my index.php, which contains the following code, directly from my browser (e.g. myserver.com/index.php), nothing appears but a white-screen:

<?php echo 'Hello php World'; ?>

When executed by php on the command line, I get the expected text output to the terminal ("Hello php World").

When, I add some HTML to index.php as in:

<html>
    <p>Hello from within html</p>
    <?php echo 'Hello php World'; ?>
</html>

and view it with my browser, it returns just "Hello from within html." However, when executed from the command line, I get:

<html>
    <p>Hello from within html</p>
    Hello php World</html>

So, the PHP is parsed and interpreted via the CLI, but not by Apache.

I have confirmed that index.php and its parent file structure are owned by apache:apache and that the selinux context of the apache modules :

chcon -t httpd_sys_script_exec_t  /usr/lib/httpd/modules/*
chcon -t httpd_sys_script_exec_t  /usr/lib/php/modules/*

and of the .php files to be parsed:

chcon -R -h -t httpd_sys_content_t /export1

are correct. I don't think selinux is the problem because I don't get any permission errors, and I've temporarily disabled selinux echo 0 >/selinux/enforce with no resultant success of the php being interpreted by apache.

The php module is being loaded with its configuration and the .php extension is being understood as configured in httpd.conf:

LoadModule php5_module /usr/lib/httpd/modules/libphp5.so
AddType application/x-httpd-php .php .phtml
PHPIniDir /etc/

And, apache knows to look for index.php from:

DirectoryIndex index.html index.html.var index.php

as set in httpd.conf.

I have exhausted my ideas of where my problem is - even tried reinstalling PHP - and sure would appreciate any ideas. In case it's of use, here are the contents of /var/log/httpd/error_log when I start up apache:

[Fri Feb 03 13:44:53 2012] [notice] SELinux policy enabled; httpd running as context unconfined_u:system_r:httpd_t:s0

PHP-CLI cannot execute scripts on Samba Share (using cifs) inside a guest VM (Centos 6)

2

I have a centos 6 VM running as a guest within Virtualbox. I've set up a LAMP stack which I am able to access from the host (Windows) environment.

I've mounted a SMB share using 'mount -t cifs' and I'm able to use apache to serve files from that share (all good so far)

problem I'm now trying to run a simple test.php script from the command line This is the output I get (below)

notice what happens if I don't spell the filename correctly (different message), so the file is there, it's as if php is unable to execute it.

I've included this as an image because I can't find any way to copy from my VM terminal. Any help appreciated, I've already spent much more time than I's imagined getting this up and running.

edit3: I AM able to run php from the command line when not trying to run a file from the samba share so it's got somthing to do with the mount. I mounted the drive thus...

mount -t cifs -o username=xxxx,password=xxxx,nounix,fir_mode=0777,file_mode=0777,gid=48,uid=48 //path/to/samba/share /var/www/vhosts

enter image description here

Changes made to cli's php.ini not taking effect

2

I have two php.ini files -

/etc/php.ini which loads in case of cli
/opt/lampp/etc/php.ini which loads in case of browser.

I am able to use PHP's Mailparse extension after adding the line extension=mailparse.so in the /opt/lampp/etc/php.ini and restarting lampp.

But I am not able to load the same in case of command line -

getting PHP Fatal error: Call to undefined function mailparse_msg_create() in ...

mailparse_msg_create() is a part of the Mailparse extension.

I tried by relogging with the user after making the change and even restarting the system. What needs to be done so that the change takes effect.

Update

I checked that php -i | grep 'Configuration File' gives

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mailparse.so' - /usr/lib/php/modules/mailparse.so: cannot open shared object file: No such file or directory in Unknown on line 0
Configuration File (php.ini) Path => /etc
Loaded Configuration File => /etc/php.ini

Update 2
I copied the mailparse.so from /opt/lampp/lib/php/extensions/no-debug-non-zts-20090626 and put it in /usr/lib/php/modules. I added extension=mailparse.so to /etc/php.ini as well. But it still showed this warning

PHP Warning:  PHP Startup: Unable to load dynamic library ...

As told by Lekensteyn, I did

ldd /usr/lib/php/modules/mailparse.so

and got

ldd: warning: you do not have execution permission for /usr/lib/php/modules/mailparse.so'

So I gave execute permission. Then

ldd /usr/lib/php/modules/mailparse.so

showed

linux-gate.so.1 => (0x00110000) libc.so.6 => /lib/libc.so.6 (0x0011d000) /lib/ld-linux.so.2 (0x003aa000)

which looks normal. BUt now, running php command says

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/mailparse.so' - /usr/lib/php/modules/mailparse.so: undefined symbol: mbfl_name2no_encoding in Unknown on line 0

Do PHP files need read permission to be executed in CLI?

2

I have a php file test.php

#!/bin/php

<?php
  echo "test";
?>

This file owned by root and its permissions are these

-rwxr-x--x

so 'others' can execute, but cannot read.

When logged in as other user than root and trying to run this file from the command line

php test.php

Got the following error

Could not open input file: test.php

If given +r permission it works.

I thought that only execute permission was needed.

Does a PHP file need read permission to 'others' to be executed in command line?

Note: using Ubuntu 10.04 LTS and PHP 5.3.2
