  • What PHP configuration and extensions are recommended for efficiency and security?

    - by Sanoj
    I am setting up an Ubuntu VPS server with nginx and PHP. I have read about many different configurations and extensions that could be added and it is pretty hard to know about all of them. I would like to hear from you, sysadmins, what PHP configuration and extensions do you recommend? I have read about: Suhosin for security Alternative PHP Cache for efficiency PHP FastCGI Process Manager for efficiency But I have no idea if they are good or not, and if I should use them together.

  • Mysteriously empty $_POST array

    - by Lex
    Hi all! I have the following HTML/PHP page: <?php if(empty($_SERVER['CONTENT_TYPE'])) { $type = "application/x-www-form-urlencoded"; $_SERVER['CONTENT_TYPE'] = $type; } echo "<pre>"; var_dump($_POST); var_dump(file_get_contents("php://input")); echo "</pre>"; ?> <form method="post" action="test.php"> <input type="text" name="test[1]" /> <input type="text" name="test[2]" /> <input type="text" name="test[3]" /> <input type="submit" name="action" value="Go" /> </form> As you can see, the form will submit and the expected output is a POST array with one array in it containing the filled in values and one entry "action" with the value "Go" (the button). However, no matter what values I enter in the fields; the result is always: array(2) { ["test"]=> string(0) "" ["action"]=> string(2) "Go" } string(16) "test=&action=Go&" Somehow, the array named test is emptied, the "action" variable does make it through. I've used the Live HTTP Headers extension for Firefox to check whether the POST fields get submitted, and they do. The relevant information from Live HTTP Headers (with a, b and c filled in as values in the textboxes): Content-Type: application/x-www-form-urlencoded Content-Length: 51 test%5B1%5D=a&test%5B2%5D=b&test%5B3%5D=c&action=Go Does anybody have any idea as to why this is happening? I'm freaking out on this one, it has cost me so much time already... EDIT: We've tried this on different servers, on Windows boxes it does work, on the Ubuntu server with PHP version 5.2.4 (with Suhosin), it doesn't. It even works on a different server, also with Ubuntu and the same PHP version, also with Suhosin installed.

  • Apache/passenger/ree doesn't interpret .rb files

    - by Sergey
    I'm trying to get apache + passenger + ree to work. I think I did everything (except for setting up rails env - for now I wanna run just pure ruby) described here: http://rvm.beginrescueend.com/integration/passenger/ But when I try to go to localhost/test.rb it doesn't interpret that file and just download it.

  • mod_access for lighttpd causes a 403 error for all POST requests

    - by Sam
    I have found on my debian server that running the lighttpd module mod_access is causing the server to response with a 403 to all POST requests. It's very odd as I have two servers, one is running as I'd expect and the other keeps returning these 403's. They are running identical configs for lighttpd and php. My lighttpd.conf is: https://gist.github.com/4269500 There is also one other custom conf: https://gist.github.com/4269508 I've opened up the servers for requests until I get this fixed, the server that works is http://mercury.isitup.org/ and the one that fails is http://venus.isitup.org/. After working out that disabling mod_access resolves the problem I greped all my lighttpd configs for uses of it (docs). Disabling each line I found didn't help, leading me to think this is perhaps some default behaviour (or bug?)... Has anyone come across this before or know what configuration value I've got wrong? Versions Debian: Debian GNU/Linux 6.0.6 (squeeze) Lighttpd: lighttpd/1.4.28 (ssl) PHP: PHP 5.3.19-1~dotdeb.0 with Suhosin-Patch (cli)

  • Do I need to recompile PHP to make use of CURL API?

    - by amn
    I have both Apache and PHP set up manually, albeit the latter without CURL. There is this jungle of instructions and explanations on extensions for PHP. I have a very straightforward question - what do I need to do to enable CURL in a more dynamic way. I resent the idea of static linking, in fact I hate and avoid static linking like the plague. Is it possible to have my Apache and PHP understand that there is CURL in town? I can compile CURL if necessary. Package management may be out of the question, because I built PHP myself - I am on Ubuntu, and it does not provide PHP without Suhosin and a a whole lot of time, so I removed it and built PHP myself. The whole slew of related questions simply propse installing "php5-curl" package, which is exactly one thing I CANNOT do since it installs it in a completely unrelated directory, which my PHP does not even seem to bother linking to.

  • Memory leak with preg_replace

    - by Silvio Donnini
    I'm using the preg_replace function to replace accents in a string, I'm working with UTF-8. I have incurred in what seems to be a memory leak, but I can't isolate the root cause, my code is rather simple: preg_replace( array_keys($aToNoAccents), array_values($aToNoAccents), $sText ); where $aToNoAccents is an associative array with entries like '~[A]~u' => 'A', '~[C]~u' => 'C',. My script prints this error for the above line: Fatal error: Allowed memory size of 1073741824 bytes exhausted (tried to allocate 3039 bytes) Obviously it's not a matter of increasing the allowed memory for PHP, (a 1Gb footprint is way off the scale of my application). Also, that line is executed thousands of times without problems but, just for some cases which are difficult to reproduce, it yields the error. Is anyone aware of memory problems with preg_replace and UTF-8 strings? Am I to use special care in passing actual parameters to such function? I'm using PHP 5.2.6-3 with Suhosin-Patch thanks Silvio

  • PHP Segmentation fault when started from crond

    - by Jeroen Moors
    Hello, I've a php script that's started each minute from cron. It almost always runs without any problem, except for about 10 times within 24h. The times it fails I get a segmentation fault like: bin/sh: line 1: 21815 Segmentation fault /usr/bin/myscript The number after "line 1:" is always different. I'm running: PHP 5.2.6-1+lenny8 with Suhosin-Patch 0.9.6.2 (cli) (built: Mar 14 2010 08:14:04) Is this a problem with my version of PHP? Is there a way to debug this? I have the feeling it crashes when the server load is high, but there's absolutely no prove for this. Any feedback is welcome!

  • How to install PHP5.3 and SQLite3 on Ubuntu 8.04

    - by richard
    Hello, I got a Ubuntu Hardy VPS and I am trying to install PHP5.3 with SQLite. I added the dotdeb PHP5.3 repository and succeeded in installing PHP5.3. But I need to install SQLite as well. When I'm trying to install php5-sqlite3 (sudo aptitude install php5-sqlite3) this is the output: The following packages are BROKEN: php5-sqlite3 The following NEW packages will be automatically installed: php-db php-pear php-sqlite3 The following NEW packages will be installed: php-db php-pear php-sqlite3 0 packages upgraded, 4 newly installed, 0 to remove and 0 not upgraded. Need to get 460kB of archives. After unpacking 3027kB will be used. The following packages have unmet dependencies: php5-sqlite3: Depends: phpapi-20060613 which is a virtual package. Resolving dependencies... The following actions will resolve these dependencies: Remove the following packages: libapache2-mod-php5 php5 php5-mysql Install the following packages: php-pear [5.2.4-2ubuntu5.10 (hardy-updates, hardy-security)] Downgrade the following packages: php5-cli [5.3.1-0.dotdeb.1 (<NULL>, now) -> 5.2.4-2ubuntu5.10 (hardy-updates, hardy-security)] php5-common [5.3.1-0.dotdeb.1 (<NULL>, now) -> 5.2.4-2ubuntu5.10 (hardy-updates, hardy-security)] php5-suhosin [5.3.1-0.dotdeb.1 (<NULL>, now) -> 0.9.22-1 (hardy)] Score is 197 Accept this solution? [Y/n/q/?] Obviously, downgrading PHP is not an option. Please help me! If upgrading the server to a newer release of Ubuntu makes things easier, that's not a problem.

Then installed the official debian packages and it worked fine... till i need install sqlite module, which give me the following error: php --version PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/pdo_sqlite.so' - /usr/lib/php5/20090626/pdo_sqlite.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php5/20090626/sqlite.so' - /usr/lib/php5/20090626/sqlite.so: undefined symbol: php_pdo_register_driver in Unknown on line 0 PHP 5.3.1-5 with Suhosin-Patch (cli) (built: Feb 22 2010 22:46:05) Copyright (c) 1997-2009 The PHP Group Zend Engine v2.3.0, Copyright (c) 1998-2009 Zend Technologies So i remember that manual install i did, and i think there is some old lib installed causing that problem, the bad thing is that there is not such make uninstall on the source code of php5... php-5.2.13 > make uninstall make: *** No rule to make target `uninstall'. Stop. I have tried reinstall and purge all php related packages via aptitude with not success. OS: Debian Squeeze. uname -a Linux desktop 2.6.32-trunk-amd64 #1 SMP Sun Jan 10 22:40:40 UTC 2010 x86_64 GNU/Linux Any idea how to fix that?

  • Apache 2.2, worker mpm, mod_fcgid and PHP: Can't apply process slot

    - by mopoke
    We're having an issue on an apache server where every 15 to 20 minutes it stops serving PHP requests entirely. On occasions it will return a 503 error, other times it will recover enough to serve the page but only after a delay of a minute or more. Static content is still served during that time. In the log file, there's errors reported along the lines of: [Wed Sep 28 10:45:39 2011] [warn] mod_fcgid: can't apply process slot for /xxx/ajaxfolder/ajax_features.php [Wed Sep 28 10:45:41 2011] [warn] mod_fcgid: can't apply process slot for /xxx/statics/poll/index.php [Wed Sep 28 10:45:45 2011] [warn] mod_fcgid: can't apply process slot for /xxx/index.php [Wed Sep 28 10:45:45 2011] [warn] mod_fcgid: can't apply process slot for /xxx/index.php There is RAM free and, indeed, it seems that more php processes get spawned. /server-status shows lots of threads in the "W" state as well as some FastCGI processes in "Exiting(communication error)" state. I rebuilt mod_fcgid from source as the packaged version was quite old. It's using current stable version (2.3.6) of mod_fcgid.

  • How to remove request blocking on apache reverse proxy after failure of backend before asking backen

    - by matnagel
    I am working on an apache2 reverse proxy vhost. When the server behind apache is down, the first request to apache shows the error page of course. But at subsequent requests it seems apache delays for some time before asking the backend server again. During all this time (which is short but in development I don't want a delay at all) only the apache error page is shown to the browser, although the backend server is already up. Where is this setting in apache, what is this behaviour, and how can I set the delay time to zero? Edit: I am not trying to change the timeout for a single request. I want to change the blocking time. It is my experience that apache blocks further requests for a certain time before asking a backend server again that has failed once. Edit2: This is what apache delivers: Service Temporarily Unavailable The server is temporarily unable to service your request due to maintenance downtime or capacity problems. Please try again later. Apache/2.2.8 (Ubuntu) PHP/5.2.4-2ubuntu5.7 with Suhosin-Patch proxy_html/3.0.0 Server at localhost Port 80 After hitting Ctrl-R in firefox for 60 seconds the page finally appears.

  • Intermittent PHP error: Undefined function <core function>

    - by Daniel
    In the last week I've been coming across an incredibly annoying error on one of Slicehost slices. It appears that every now and then PHP will fail with a fatal error, saying a certain function is undefined. The function changes, but is always a core PHP function e.g. defined(), version_compare(), etc. This problem has occurred while using several different PHP applications - PHPMyAdmin, my own custom built apps, etc, leading me to believe that the problem is not specific to the running code. Here are some details: - Debian Lenny - Apache 2.2.9 - PHP 5.2.6-1+lenny4 with Suhosin-Patch (running eAccelerator 0.9.6) Apache and PHP are installed from Debian packages. Error logs show nothing out of the ordinary. I thought memory might be an issue, but free -m reports upwards of 100MB free almost all the time. Another thing I'm trying to investigate is if the problem might be related to eAccelerator, but testing this theory out is incredibly hard because the issue doesn't appear very often and I've been using eAccelerator for months on this install without any problems up until now. Has anyone ever come across anything like this? Why would PHP report undefined core functions?

  • Issues with ASP.NET via Apache/mod_mono on Ubuntu.

    - by Matthew Scharley
    I run an Ubuntu test server, and my deployment system is also Ubuntu. I've recently been trying to get ASP.NET to work on my test server so that we can take it live. I managed to get it installed, and configured properly, and my application is installed and running, but I can't get anything to work. The error I keep receiving is below, if anyone has any clue what might be going on, it would be greatly appreciated. Server Error in '/' Application Standard output has not been redirected or process has not been started. Description: HTTP 500. Error processing request. Stack Trace: System.InvalidOperationException: Standard output has not been redirected or process has not been started. at System.Diagnostics.Process.CancelErrorRead () [0x00000] at (wrapper remoting-invoke-with-check) System.Diagnostics.Process:CancelErrorRead () at Mono.CSharp.CSharpCodeCompiler.CompileFromFileBatch (System.CodeDom.Compiler.CompilerParameters options, System.String[] fileNames) [0x00000] at Mono.CSharp.CSharpCodeCompiler.CompileAssemblyFromFileBatch (System.CodeDom.Compiler.CompilerParameters options, System.String[] fileNames) [0x00000] at System.CodeDom.Compiler.CodeDomProvider.CompileAssemblyFromFile (System.CodeDom.Compiler.CompilerParameters options, System.String[] fileNames) [0x00000] at System.Web.Compilation.AssemblyBuilder.BuildAssembly (System.Web.VirtualPath virtualPath, System.CodeDom.Compiler.CompilerParameters options) [0x00000] at System.Web.Compilation.AssemblyBuilder.BuildAssembly (System.Web.VirtualPath virtualPath) [0x00000] at System.Web.Compilation.BuildManager.BuildAssembly (System.Web.VirtualPath virtualPath) [0x00000] at System.Web.Compilation.BuildManager.GetCompiledType (System.String virtualPath) [0x00000] at System.Web.HttpApplicationFactory.InitType (System.Web.HttpContext context) [0x00000] Version information: Mono Version: 2.0.50727.42; ASP.NET Version: 2.0.50727.42 Apache version String: Apache/2.2.11 (Ubuntu) mod_mono/2.0 PHP/5.2.6-3ubuntu4.2 with Suhosin-Patch Server at dev Port 80 PS: I had to add three DLL's to the /bin directory in my application, copying them from Windows because I couldn't find them in any of Mono's packages. This might or might not be causing problems, I don't know. The list that I had to add is: System.Web.Abstractions System.Web.Routing System.Web.Mvc

  • Apache / PHP Begins to Deny SQL Requests after about 2000

    - by Daniel Stern
    We have a web page on our server that we use to run administrative scripts. For example, we might run the script "unenrolStudents()" which runs 5,000 SQL SET commands one after another and sets 5000 student entries in an SQL database to unenrolled. However, we are finding that after running a few thousand queries (it is not totally consistent) we will be "locked out" by our server. SYMPTOMS OF LOCKING OUT: - unable to connect to server with winSCP - opening putty with that connection shows a blank screen (no login / pass) - clearing cookies / cache in chrome does NOT fix locking out - other computers in the office ALSO become locked out - locking out can be triggered with a high frequency of requests (10000 in 1 second) or by less over time (10000 in 500 seconds - this will still cause a lockout even though the frequency is much less) We believe this is a security feature of our own Apache. I know we are using Suhosin but I didn't configure it so I don't know. How can I disable this locking effect so that I can confidently run all my SQL requests and they will go through? Has anyone else dealt with this and found workarounds? Thanks DS
