I let my host upgrade php version to 7.2 and after that I am getting error 500 message(Internal Server Error) on my wordpress page.
I am using Virtualmin.
When opening error log I get the following:
[Mon Jan 06 16:04:41 2020] [error] (13)Permission denied: exec of '/etc/httpd/bin/suexec' failed
[Mon Jan 06 16:04:41 2020] [error] Premature end of script headers: php7.2.cgi
I searched for the solution elsewhere but didn't find any solution.
How can I solve this?
You can go to >>> virtualmin >>> serve configuration >> website options
And make the change to
FCGI, fpm or what your system is available
I can't figure out the exact solution, but the web host told me that because this server had somehow been accessed by malware, this whole thing had to be closed down and the domain moved to a new address.
Moving domain to a new server solved this problem.
This would be something to ask your Hosting Provider, Potentially they have changed the PHP Handler (Eg from suPHP to FastCGI)
you have upgraded PHP, but your Virtualmin is not configured to use it correctly.
On Virtualmin go to system settings -> Re-check configuration, Virtualmin will detect new PHP version and configure it to use on your server.
I'm currently experimenting with a PHP plugin called Mosquitto PHP (https://github.com/mgdm/Mosquitto-PHP/). I've got it all installed right, and under 'php -m' it seems to show up properly.
I'm using a small test code to see if it in it's basic form works:
<?php
$c = new Mosquitto\Client;
$c->onConnect(function() use ($c) {
$c->publish('mgdm/test', 'Hello', 2);
});
$c->connect('test.mosquitto.org');
for ($i = 0; $i < 100; $i++) {
// Loop around to permit the library to do its work
$c->loop(1);
}
echo "Finished\n";
?>
And that seemed to return "Finished" in my browser. So, I decided to up my game, and add a TLS connection, as documented, to this:
<?php
$c = new Mosquitto\Client;
$c->onConnect(function() use ($c) {
$c->publish('mgdm/test', 'Hello', 2);
});
$c->setTlsCertificates('mosquitto.org.crt');
$c->connect('test.mosquitto.org', '8883');
for ($i = 0; $i < 100; $i++) {
$c->loop(1);
}
echo "Finished\n";
?>
I got the certificate and I've made sure apache2 could read it and set the ownership subsequently to apache2. This turned out to give me the 500 internal sever error in my browser.
-rwsrwsrwt 1 www-data www-data 279 Jun 5 04:12 test.php
-rwxrwxrwx 1 www-data www-data 1078 Jun 30 2012 mosquitto.org.crt
Out of curiousity, I navigated to the script in shell and ran it with:
sudo php test.php
This resulting in a printed "Finished" in my ssh, and it sent the message through the broker.
This made me think it's an odd sort of permission error. Investigating further, I found these in my logs:
My apache2 log:
mod_fcgid: process /var/www/php-fcgi-scripts/web1/.php-fcgi-starter(20614) exit(communication error), get unexpected signal 11
mog_fcgid installed is:
libapache2-mod-fcgid 1:2.3.9-1+b1 amd64 FastCGI interface module for Apache 2
and it is, same with suexec is enabled as far as I can tell.:
Module fcgid already enabled
Module suexec already enabled
In a small twist of events, I changed the .php to .fcgi and gave it +x permission, and now the messages goes through the broker, but still it gives a 500 error in my browser.
suexec log shows:
[2016-06-07 14:05:58]: uid: (5004/web1) gid: (5005/client0) cmd: test.fcgi
and in my ispconfig log it shows:
[Tue Jun 07 14:08:25.567945 2016] [fcgid:warn] [pid 27861] (104)Connection reset by peer: [client 93.135.88.60:49328] mod_fcgid: error reading data from FastCGI server

I'm totally lost for words here.. I need help!!
Try to increase the memory for php-fcgi (by default for cli memory_limit=-1).
I think this case should resolve your problem.
UPDATE
I have installed mosquitto (from php7 branch) and try it (run test.php from repository examples. php 7.0.7). And i have segfault to
segfault at 8 ip 00005574a41c753f sp 00007ffc2dc85da0 error 6 in php7.0[5574a3f80000+391000]
It seems that this is extension bug.
You can try to debug this segfault (https://bugs.php.net/bugs-generating-backtrace.php) and send report to extension developers.
i have a VPS mounted with RedHat OS. Today, install DAV module for Apache from WHM and the services was restated.
Apache works fine, but PHP has troubles. All my php scripts return 501 Internal Server Error.
In the log /usr/local/apache/logs/error_log i can see:
[error] [client 190.247.67.31] Premature end of script headers:
info.php
And PHP command line doesn't work. When i try php -v the command doesn't show the PHP version and nothing is returned.
Note: PHPMyAdmin works.
Any ideas ?
In my case the problem was an incorrect php.ini configuration.
I'm on a relatively fresh install of Ubuntu and this is the first time I've used the local web server on it.
The problem I have is that when I try and access a php file I get a 500 error.
To try and solve it I've:
Renamed index.html to index.php in /var/www to make sure it's not a virtualhost error (standard "it works" file)
given 0777 permissions to both /var/www and the index.php file
made www-data the owner of the directory and the file
made www-data the group for the directory and the file
checked the error log
trawled Google
The error log shows:
[Sat Sep 07 13:18:56 2013] [notice] Apache/2.2.22 (Ubuntu)
PHP/5.4.9-4ubuntu2.3 configured -- resuming normal operations
which I understand means the PHP is loading correctly
The only entry I do not understand is
[Sat Sep 07 13:19:00 2013] [error] [client 127.0.0.1] Premature end of
script headers: index.php
I've done searches but most of the articles I've found are no help.
Is there anything else I can do to try to debug the error or does anybody have any ideas as to why this error is happening?
Thanks in advance,
Is error reporting on in php?
try adding:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
on the first line of the script after
First of all thanks for VIVEK-MDU for the suggestions and changes to my post. I must admit that I thought the lists were done automatically (I never got into markdown (just seen I missed the space before the minus sign on the list items)).
Answer?
Unfortunately I cannot help anybody who lands at this page with a similar problem.
I also develop on my laptop which has a similar setup. after copying:
/etc/apache2/
/etc/hosts
/var/www - the correct permissions for my system are my-user (not root or www-data)
The system now works as expected. Again: sorry I can't help anybody else but thanks to everyone who looked and the people that helped.

I am having issue on PHP where my app is trying to run a php backup file and suddenly getting HTTP Error 500 Code. I have checked the logs and this what it saying.
[Tue Aug 28 14:17:28 2012] [warn] [client x.x.x.x] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server, referer: http://example.com/backup/backup.php
[Tue Aug 28 14:17:28 2012] [error] [client x.x.x.x] Premature end of script headers: backup.php, referer: http://example.com/backup/backup.php
Anyone knows how to fix this? I'm really stuck in here and can't find solution in internet.
Hope anyone could share their knowledge.
Thanks.

I managed to solved this by adding FcgidBusyTimeout . Just in case if anyone have similar issue with me.
Here is my settings on my apache.conf:
<VirtualHost *:80>
.......
<IfModule mod_fcgid.c>
FcgidBusyTimeout 3600
</IfModule>
</VirtualHost>
I had very similar errors in the Apache2 log files:
(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
Premature end of script headers: phpinfo.php
After checking the wrapper scripts and Apache2 settings, I realized that /var/www/ did not have accordant permissions. Thus the FCGId Wrapper scripts could not be read at all.
ls -la /var/www
drwxrws--- 5 www-data www-data 4096 Oct 7 11:17 .
For my scenario chmod -o+rx /var/www was required of course, since the used SuExec users are not member of www-data user group - and they should not be member for security reasons of course.
if you want to install a PHP version < 5.3.0, you must replace
--enable-cgi
with:
--enable-fastcgi
in your ./configure statement, excerpt from the php.net doc:
--enable-fastcgi
If this is enabled, the CGI module will be built with support for FastCGI also. Available since PHP 4.3.0
As of PHP 5.3.0 this argument no longer exists and is enabled by --enable-cgi instead. After the compilation the ./php-cgi -v should look like this:
PHP 5.2.17 (cgi-fcgi) (built: Jul 9 2013 18:28:12)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies
NOTICE THE (cgi-fcgi)
I had this issue and realized that the file cgi-bin/php-fcgi had no execution rights.
It had 644 mode while is should have 755 mode.
Setting the correct mode was impossible (probably because the file was opened or sth), so I copied that file from another domain directory where it had proper rights already set and that fixed everything.
I had the same problem with a different and simple solution.
Problem
I installed PHP 5.6 following the accepted answer to this question on Ask Ubuntu.
After using Virtualmin to switch a particular virtual server from PHP 5.5 to PHP 5.6, I received a 500 Internal Server Error and had the same entries in the apache error log:
[Tue Jul 03 16:15:22.131051 2018] [fcgid:warn] [pid 24262] (104)Connection reset by peer: [client 10.20.30.40:23700] mod_fcgid: error reading data from FastCGI server
[Tue Jul 03 16:15:22.131101 2018] [core:error] [pid 24262] [client 10.20.30.40:23700] End of script output before headers: index.php
Cause
Simple: I didn't install the php5.6-cgi packet.
Fix
Installing the packet and reloading apache solved the problem:
sudo apt-get install php5.6-cgi if you are using PHP 5.6
sudo apt-get install php5-cgi if you are using a different PHP 5 version
sudo apt-get install php7.0-cgi if you are using PHP 7
Then use service apache2 reload to apply the configuration.
The famous Moodle "replace.php" script can generate this situation too.
For me it was taking ages to run and then failed with a 500 message in the browser and also with the above error message in my apache error log file.
I followed up on #james-wise answer:
FcgidBusy is readably described in the Apache documentation. I tried this: doubled the amount of time which apache would give my script to run, by inserting the following line in /etc/apache2/mods-available/fcgid.conf
FcgidBusyTimeout 600
Then I restarted Apache and tried to run my replace.php script again.
Fortunately this time the script instance ran to completion, so for my purposes this served as a solution.
I came across this one while debugging a virtualmin/apache related error.
In my case, I am running virtualmin and had in my virtual machine's php.ini
safe_mode=On.
In my Virtual Machine's error log, I was getting the fcgi Connection reset by peer: mod_fcgid: error reading data from FastCGI server
In my main apache error log I was getting:
PHP Fatal error: Directive 'safe_mode' is no longer available in PHP in Unknown on line 0
In my case, I simply set safe_mode = Off in my php.ini and restarted apache.

Not in this questions askers case but often:
What does the "premature end of script headers" error mean?
That error means that the FCGI call was exited unexpectedly.
In some cases it means that the script "backup.php" did crash.
How to fix this?
If the crash of a script was the cause, fix the script so that it does not crash. Then this error is fixed, too. To find out if and why a script crashes, you need to debug it. For example you can check the PHP error log. Errors logged to STDERR normally go into the error handler of the FCGI.
I had the same problem with long-running scripts with the error messages
"Premature end of script headers: index.php" and "Connection reset by peer: mod_fcgid: error reading data from FastCGI server" in error_log.
After hours of testing this helps for me (CentOS 6, PHP-FPM 7, Plesk 12.5.30):
edit the config file:
/etc/httpd/conf.d/fcgid.conf
Set a higher running time. In my case 600 seconds
create the new entry:
FcgidBusyTimeout 600
adapt following entries:
FcgidIOTimeout 600
FcgidConnectTimeout 600
restart httpd:
service httpd restart
In CentOS releases suexec is compiled to run only in /var/www. If you try to set a DocumentRoot somewhere else you have to recompile it - the error in apache log are:
(104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
Premature end of script headers: php5.fcgi
Just install php5-cgi
in debian
sudo apt-get install php5-cgi
in Centos
sudo yum install php5-cgi
Check /var/lib/php/session and its permissions. This dir should be writable by user so the session can be stored
As already mentioned this could be happening due to fcgi handler permission issues. If you're using suexec - don't forget to check if apache has this module enabled.
I increased max execution time to 600 seconds job done !
If you're on a shared server like me the host said it was a result of hitting memory limits, so they kill scripts which results in the "Premature end of script headers" seen in this error. They referred me to this:
https://help.dreamhost.com/hc/en-us/articles/216540488-Why-did-procwatch-kill-processes-on-my-Shared-serv
Given an increase in memory, the issues went. I think a backup plugin Updraft on wordpress was perhaps over zealous in its duty/settings.
In my case I was using a custom extension for my PHP files and I had to edit /etc/apache2/conf-available/php7.2-fpm.conf and add the following code:
<FilesMatch ".+\.YOUR_CUSTOM_EXTENSION$">
SetHandler "proxy:unix:/run/php/php7.2-fpm.sock|fcgi://localhost"
</FilesMatch>
I've tried the majority of answers that I've found on this issue. My issue was with wp-cron.php executing a particular function.
I'm working on Plesk CentOS7, Apache server.
I used this related question and suggested answer to help me find out how to adjust the fcgid.conf memory limit utilizing the command line.
Upon trying to troubleshoot the limits on the fcgid.conf file (/etc/httpd/conf.d/fcgid.conf) and restarting apache gracefully, I found that there was no change.
After seeing that other cron jobs were running properly, I decided to refer back to my function declared in functions.php and found that some of the arguments declared were not being specified properly, so there was a loop occurring that would eventually lead to the timeout.
Upon fixing this and running the cron again, it ran as it should.
Hope this helps someone else in a similar position!
I got the same problem (with Plesk 12 installed).
However, when i switched from execute PHP as FastCGI to Apache Module the website worked.
Checked my suexec log:
$ cd /var/log/apache2/
$ less suexec.log
When you find something like this:
[2015-03-22 10:49:00]: directory is writable by others: (/var/www/cgi-bin/cgi_wrapper)
[2015-03-22 10:49:05]: uid: (10004/gb) gid: (1005/1005) cmd: cgi_wrapper
try this commands
$ chown root:root /var/www/cgi-bin/cgi_wrapper
$ chmod 755 /var/www/cgi-bin/cgi_wrapper
$ shutdown -r now
as root.
I hope it can help you.
