PHP-FPM dynamic variable environment unknow (4 replies)

Greetings,

I have installed the latest version of PHP-FPM, Apache and mod_fastcgi.

All is working, except the ENV arn't GLOBAL.
I can get the IP of the visitor with $_SERVER['REMOTE_ADDR'] from a script
PHP, but i can't use this information from my mail wrapper sendmail.pl
wrote in Perl.

Before to use PHP-FPM / FastCGI, i had suphp and all were correct, even
inside my wrapper sendmail.pl in Perl.

When i check my phpinfo(), "Environment" is mostly empty, i have only USER
and HOME.

I know i can fill this part with php-fpm.conf with this :
env[MY_ENV_VAR_1] = 'value1'

and it's working, this variable is global. But how can i set REMOTE_ADDR
which is a dynamic value with the visitor ?

I have tried this :
env[REMOTE_ADDR] = $REMOTE_ADDR

but the variable $REMOTE_ADDR is empty, even if $_SERVER["REMOTE_ADDR"] is
still here, but not in GLOBAL.

I have tried this :
env[REMOTE_ADDR] = $_SERVER["REMOTE_ADDR"]

And $REMOTE_ADDR is still empty.

I have tried again this :
env[REMOTE_ADDR] = $_SERVER["REMOTE-ADDR"]

And $REMOTE_ADDR is always empty, even if $_SERVER["REMOTE_ADDR"] is still
here.

Do you have an idea please ?

Hello,

I installed a joomla on a httpd in /var/www/html and that worked well. I tried to switch to nginx / php-fpm.
When I try mydomain.fr/index.html I've a nginx standard page. When I try the mydomain.fr/index.php I get the "No input file specified." message.

In the nginx logs, I get following:
2013/11/07 23:11:12 [error] 29996#0: *58 FastCGI sent in stderr: "Unable to open primary script: /var/www/html/index.php (No such file or directory)" while reading response header from upstream, client: 88.173.xxx.xxx, server: e-lang.fr, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "mydomain.fr".

I've nothing in the php-fpm logs. The path that generated is good. Php is ran with apache user that has r/x rights on all file hierarchy. Nginx user has also same rights.

Some people of Nginx irc said me that was a "php" problem, but since I've no message and I don't no well any of theses systems, I do not find solution on the net.

Can you help me please ?

What information do you need to better help me ?

Thanks a lot.

Nginx + PHP5-fpm doesn't complete the processing (no replies)

I'm trying to convert from Apache to Nginx, and it's not going too bad. However, there is a problem that I've encountered with our API, which outputs quite a lot of stuff and can take up to 1 second when regenerating the cache. It seems to work ok from time to time, but most of the time the output is truncated to 24296 characters, consistently.

I've tried this script:


<?php

$str = '';
while(strlen($str)<524297){
$str .= strlen($str).'<br />';
}

echo $str;


which outputs the following:

0<br />7<br />14<br />22<br />30<br /> [...etc...] />102284<br />102296<br />1023

A total of 102313 characters, every time. This indicates it could be a memory issue, so I did this instead:


$str = '';
while(strlen($str)<524297){
$str .= memory_get_usage().'<br />';
}

echo $str;


Which gets up to

772616
7726

.. even though php.ini says memory_limit=512M

I wonder if it's a time limit, so I do this instead:


$start = microtime(true);
while(strlen($str)<524297){
$str .= (microtime(true)-$start).'<br />';
}

echo $str;


0.0083520412445068
0.0083539485931396
0.008357048034668

( total of 89793 characters)



The thing I really don't understand, is why, if the string length has not exceeded 524297 characters, does it quit looping and start printing?

Pretty confident that solving this is the only thing holding us back from testing.

Thanks!

Hi,

What is the kernel version?

Have you verified the memories w/ e.g. Memtest?

How busy are these web servers? Is it related to high load or only a few visits cause this?

Hello,

I have a few busy web servers using nginx with php-fpm and some of them
started getting lots of segfaults and general protection errors in dmesg.

PHP 5.4.21

Does anyone have any clues what could cause them or how to trace this? It
seems there is no impact on user experience, no 500 errors or anything, but
I would like to know what is happening.

Thanks

my server will serv 400req/s at peak. i found at that time ,php finished

immediately(about 10 seconds,nginx got nothing from upstream(the php-fpm
)), it cause the client abort the request and make nginx responds with 499
error. the server seems at a fine load,enough ram,enough cpu,io is not high.
anyone has this situation?

Nginx fails to connect to PHP-FPM at 1400-1500 rps (no replies)

Hello!

I have PHP-FPM 5.4.4 running on Debian 7 and Nginx 1.4.1.
At ~1500rps PHP fails to accept new connections, there are lot of
connection in state SYN_SENT or SYN_RECV to tcp port of PHP. In 'normal'
conditions there are only few (or zero) such connection.

Here is my modification over default Debian's sysctl settings:

net.core.rmem_default=16777216
net.core.netdev_max_backlog=262144
net.core.somaxconn=262144

net.ipv4.tcp_syncookies=1

net.ipv4.tcp_max_syn_backlog=262144
net.ipv4.ip_local_port_range=1024 65535
net.ipv4.tcp_tw_reuse=1

Here is what I see in 'strace' of PHP worker process during problem period:

Please, note poll() timeout at 23:50:29.413992

So it look like under some conditions PHP either Linux kernel fails to work
correctly with new TCP connections, which are hangs in SYN_RECV or SYN_SENT
state, while PHP fails to get new connection descriptir to perform accept().

I have rlimit_files=128000 both for master process and pool workers, pm is
static, backlog=512.

Understanding the slow log stack trace (2 replies)

Hi,

I'm trying to make sense of the stack trace of PHP-FPM's slow log feature.
But I'm not sure how I should interpret it.

I notice that some of the stack traces in my log start (or actually end,
since the ordering is most recent on top) with a __construct() call, this
confuses me. What does the top item in the list represent?

A) Is it: That specific call took longer than the configured time limit,
the stack simply shows all calls before it
B) Or is it: The entire stack exceeded the time limit, due to the sum of
that call including all previous. The top most call is simply the one going
over the threshold. There might be calls after it, but those are not shown
C) Or is it: This is the entire stack of the request, that in total took
longer than the configured time, no calls came after it.

Stack trace gist: https://gist.github.com/Dynom/156e5fa1217ce527dd39


Thanks for reading.

Can't make Nginx 1.5.7 to work with PHP5-FPM (no replies)

Hello all,

I've installed the last Nginx mainline 5.1.7 on a fresh install of Ubuntu 12.04.3 LTS 64 running PHP5-FPM 5.5.6-1.

My simple problem is that I can't make Nginx to work with PHP5-FPM.

Any request to a PHP file results in a Not found message.

Below are my settings:

etc/nginx/nginx.conf

user nginx;
worker_process 8;
error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;
events {
worker_connections 8192;
}
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log off;
sendfile on;
tcp_nopush on;
keepalive_timeout 64;
gzip on;
gzip_min_length 500;
include /etc/nginx/conf.d/*.conf;
}

etc/ngin/conf.d/default.conf

server {
listen 80;
server_name localhost;
access_log off;
location / {
root /var/www;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /var/www;
}
location ~ \.php$ {
root html
fastcgi_pass 127.0.0.1:9000;
# fastcgi_pass /var/run/php5-fpm.sock;
fastcgi_index index.pp;
fastcgi_parms SCRIPT_FILENAME /scripts$fastcgi_script_name;
include fastcgi_params;
}
}

/etc/php5/fpm/php-fpm.conf

[global]
pid = /var/run/php5-fpm.pid
error_log = /var/log/php5-fpm.log
include=/etc/php5/fpm/pool.d/*.conf

/etc/ph5/fpm/pool.d/www.conf

[www]
user = www-data
group = www-data
listen = 127.0.0.1:9000
; listen = /var/run/php5-fpm.sock
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

Now, whenever I change the listen directive to /var/run/php5-fpm.sock in both /etc/nginx/conf.d/default.conf and /etc/php5/fpm/pool.d/www.conf does not change the problem.

Any help and advice would be truly appreciated since I'm sure I'm wrong somewhere.

TIA.

Offloading PHP-FPM to multiple servers (4 replies)

Hello,

I have a web server that is being overloaded with PHP-FPM requests which is
killing my CPU. I am looking to offload PHP-FPM processing onto multiple
servers with lots of CPU cores. Can someone tell me what all is required
to make this happen, in terms of does the offloading FPM servers need to be
able to see the docroot of the web server? I was thinking a NFS share on
the web server would accomplish this as I would mount the NFS on the FPM
offloading servers.

Is there anything else I am missing that would stop me from simply
deploying some FPM processing servers and using ProxyPass to load balance
the requests to the FPM servers? Is this a common thing people do to serve
up large sites?

Thanks,
Cody

Is each php-fpm pool having their own memory pool? (1 reply)

I am using the PHP 5.5 opcode cache, and set

opcache.memory_consumption=128


1. if I have 4 pools in php-fpm, will each of the 4 pool share 128MB of
cache, or will they own 128M opcache for each pool?

2. If these 4 pools share the same PHP codes library (assume 10MB), do I
need 40MB for opcache since I have 4 pool?


Or any place I can find the information?


Thanks.

Hi Team,

Today i got a very strange error . In my server i have deployed 3 php web application . which are bult using yii ,laravel php and wordpress frameworks . but one my website is loading very slow. when i see error log .. for every one minute 2 errors are logged .. same error repeated for whole day

Here is the error info

apparmor support for php-fpm (no replies)

Hello,

about half a year ago I wrote an RFC for php for imlementing apparmor
change_hat functionality to php-fpm
(https://wiki.php.net/rfc/fpm_change_hat,
https://github.com/php/php-src/pull/373). It didn't have much support at
the time (only three votes, but all yes). Since php 5.6 alpha should be
released any day and it would be nice to get in, could anybody here help
with getting the pull request pulled?

Cheers,
Gernot Vormayr

Optimal values for process manager (no replies)

January 20, 2014, 11:24 pm
$

Folks,

I have a couple of servers with php5-fpm using up more RAM than I think it
should be. The process manager settings for both servers are below:

pm.max_children = 10

pm.start_servers = 4

pm.min_spare_servers = 2

pm.max_spare_servers = 6

According to the config file, the default value for *pm.start_servers* is *min_spare_servers
+ (max_spare_servers - min_spare_servers) / 2*

But what is the best value for *pm.min_spare_servers* and
*pm.max_spare_servers* on a server with 512 MB of RAM and 1 CPU?

TIA
