Hello,
I'm struggeling with the maximum number of open files in a php script executed
through the
apache web server.
I have done two tests - one from shell and one through the apache web server.
Both tests
open as many files as possible in a given folder (named a-00001.dat,
a-00002.dat and so
on).
The initial test resulted in 1006 open files through the apache web server, and
about 1020
from the shell.
By playing with the /etc/security/limits.conf and /etc/sysctl.conf I managed to
increase
the number of files from the shell to about 2000 (then the limit was set to
8190 files
(soft limit was 8192 in /etc/security/limits.conf).
But through the apache web server, it is still only 1006.
The content of /etc/security/limits.conf:
* soft nofile 8192
* hard nofile 16348
apache soft nofile 8192
apache hard nofile 16348
The apache web server was restarted after I changed the
/etc/security/limits.conf file.
I executed 'print_r(posix_getrlimit())' in a php script through the apache web
server and
got this output:
Array
(
[soft core] => unlimited
[hard core] => unlimited
[soft data] => unlimited
[hard data] => unlimited
[soft stack] => 8388608
[hard stack] => unlimited
[soft totalmem] => unlimited
[hard totalmem] => unlimited
[soft rss] => unlimited
[hard rss] => unlimited
[soft maxproc] => 62856
[hard maxproc] => 62856
[soft memlock] => 65536
[hard memlock] => 65536
[soft cpu] => unlimited
[hard cpu] => unlimited
[soft filesize] => unlimited
[hard filesize] => unlimited
[soft openfiles] => 1024
[hard openfiles] => 4096
)
For me it seems like php is setting a limit, or??
I'm using php 7.0.25 and apache 2.4.27
