[NoResponse] 500 Internal Server Error

Added by Ireng almost 7 years ago

I installed Nextcloud 12 and after entering username and password I am hiiting the Login buttoan and always receive an 500 - Internal Server Error !

lighttpd 1.4.45, DEBIAN 9, php7.0

My lighttpd.conf shows like this :

2017-07-05 15:38:42: (server.c.1828) server stopped by UID = 0 PID = 1

which is far outdated. No current entry is available!

Any idea to resolve the situation ??

Find the PID of the currently running lighttpd process, then restart it and check it actually was restarted by looking for the PID again - it needs to be a new one.

As you are probably running systemd you should take a look at systemctl status lighttpd.service and journalctl -u lighttpd.service too.

RE: 500 Internal Server Error - Added by stbuehler almost 7 years ago

It seems permission with nextcloud are a problem, e.g:

PHP Warning:  fileperms(): stat failed for /var/www/servers/nextcloud/data/nextcloud.log

As you spawn php from lighttpd this means php is probably running as www-data (same as lighttpd itself), so the www-data user needs write permissions accordingly.

As an alternative you could run php as a different user by spawning it through php-fpm, spawn-fcgi or systemd; in that case remove the "bin-path" option in the lighttpd fastcgi config, and just point it to the socket php is running at (again: www-data will need permissions to access this socket).

PHP crashing in libMagickCore is certainly not a good sign either; you might want to report that (unless someone else already did of course).

The strace output is not useful; you shouldn't specify a binary name when you want to trace a running process, but if you do the strace options (-o strace.output) must come before the binary (because it spawns the binary with all options after it, and traces process too).
The part from the strace output regarding the already running lighttpd shows only idle time - there is no request coming in.

You also might want to check the response headers of the requests resulting in "500 - Internal Server Error" - it looks like PHP is the origin of these.

Regarding the lighttpd error log: please note that there are no per-vhost error logs, only a global one; and it looks like you point it to syslog or stderr in some of the included config files, which is why the log ends up in journalctl (nothing wrong with that though, but /var/log/lighttpd/error.log will stay untouched).

RE: 500 Internal Server Error - Added by Ireng almost 7 years ago

@stbuehler, many thanks for your comprehensive answer. i will test all your suggestions one by one!

-rw-r--r-- 1 www-data www-data      0 Jul 14 16:34 nextcloud.log

is the current stae and I changed it to

-rw-rw-r-- 1 www-data www-data      0 Jul 14 16:34 nextcloud.log

However, this did not change the error message
Same holds true for

Permission problems can go up the directory tree (you need +x to enter a directory), but the file permissions look fine as they were before (as long as php is running as www-data).

Well, the php process is still running as www-data. You'd need to configure a different pool with a different username (and socket!) to test running as the "nextcloud user".

RE: 500 Internal Server Error - Added by stbuehler almost 7 years ago

Just because the socket files still exist doesn't mean they're active; the ones with a -$n suffix were created by lighttpd ("max-procs" uses a different socket for each spawned backend).

Also NEVER put unix socket files into a world writable directory (i.e. /tmp or /var/tmp).

If you spawn the backend with lighttpd, you'll need a directory in /run or /var/run which is owned by www-data (usually /run/lighttpd/).

If spawned by something with root permissions (php-fpm, systemd, spawn-fcgi) you can put them directly into /run or /var/run.

However in lighttpd.conf (looka ta the beginning of this thread)

#    "bin-path" => "/usr/sbin/php-fpm7.0",
     "bin-path" => "/usr/bin/php-cgi7.0",
#    "bin-path" => "/usr/bin/php7.0",

isn't activated ! How come ??

RE: 500 Internal Server Error - Added by stbuehler almost 7 years ago

php-fpm is its own service, and is not spawned by lighttpd. If you don't want php-fpm anymore you probably should just uninstall it.

Assuming you're using systemd, try this command:

systemctl status

It should show for each process through which unit it was spawned.

Well, again thanks for yor valuable help and insight!

i am just thinking of reverting back to Jessie 8.8, at a time when everything was running up to expectations!

RE: 500 Internal Server Error - Added by Ireng almost 7 years ago

I found out, that static html pages will be displayed nicely !

However, php scrips are still in trouble!

Internal Server Error

The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

( no error messages in error.log it is empty!)

I'll try to fix it by adjusting the php.ini at /etc/php/7.0/cgi !

Does anybody have an idea for what i should look for ??

Hopefully I will succeed!

RE: 500 Internal Server Error - Added by Ireng almost 7 years ago

the following script produces 500 Internal server error

<?php
echo "Die aktuelle PHP Version ist " .phpversion();
phpinfo();
?>

Why ???
reagrds, Ireng

installed php7.0 from DEBIAN 9

RE: 500 Internal Server Error - Added by stbuehler almost 7 years ago

We went through a lot of configurations and log messages, so it would be helpful if you added these for this specific problem. strace output (e.g. strace -p $(pidof lighttpd)) while you make the request might be helpful too.

in addition I do have some messages from mysqld:
maybe ist helps to narrow down the problem:

key_buffer_size=16777216
read_buffer_size=131072
max_used_connections=0

thread_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 352433 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

RE: 500 Internal Server Error - Added by stbuehler almost 7 years ago

There seems to be one connection (one accept4), but two requests. The first seems to be for /index.php and returns 302:

stat("/var/www/servers/nextcloud/index.php", [...]) = 0
[...]
read(9, "\1\6\0\1\3\v\5\0Status: 302 Found\r\nExpir"..., 1087) = 808

The second seems to be for /index.php/login and returns 500:

stat("/var/www/servers/nextcloud/index.php/login", 0x7fff007e6000) = -1 ENOTDIR (Not a directory)
[...]
read(9, "\1\6\0\1\4\1\7\0Status: 500 Internal Ser"..., 1087) = 1056

I'm not sure whether it handles PATH_INFO for the second request (i.e. split into /index.php for the script and /login for PATH_INFO); it might use cached stat information for that.

A crashing mysqld is always bad, but should only create issues in php if you actually try to connect. You claimed your simple example script already triggered a 500 (which doesn't use mysql), but it doesn't contain a redirect.
