Edit report at https://bugs.php.net/bug.php?id=49616&edit=1 ID: 49616 Comment by: jack dot chuong at itlvn dot com Reported by: ben at realitychecknetwork dot com Summary: Impossible to increase SOMAXCONN Status: Closed Type: Feature/Change Request Package: Feature/Change Request Operating System: Linux 2.6.18 PHP Version: 5.2.11 Block user comment: N Private report: N New Comment: I'm trying to compile php 5.5.16 on Centos 6.4 64 bit to increase SOMAXCONN After add to file: /usr/include/linux/socket.h #define SOMAXCONN 256 cat /proc/sys/net/core/somaxconn 256 cat test.php <?php echo SOMAXCONN; ?> php test.php 128 Previous Comments: ------------------------------------------------------------------------ [2009-09-23 03:12:48] ben at realitychecknetwork dot com In CentOS5.3 its actually : /usr/include/linux/socket.h Thanks, that did the trick. Replace: /* Maximum queue length specifiable by listen. */ #define SOMAXCONN 128 With: /* Maximum queue length specifiable by listen. */ #define SOMAXCONN 2048 Then recompile PHP ------------------------------------------------------------------------ [2009-09-22 09:38:30] sjoerd@php.net PHP uses the SOMAXCONN from sys/socket.h at compile time. ------------------------------------------------------------------------ [2009-09-21 20:22:24] ben at realitychecknetwork dot com Description: ------------ Impossible to increase SOMAXCONN value by updating system OS variable. PHP must be compiled with --enable-sockets for this bug to be produced. OS setting updated with: # sysctl -w net.core.somaxconn=2048 net.core.somaxconn = 2048 PHP will always return 128 for SOMAXCONN and will not respect the OS setting. Additionally, it will ignore a define statement in PHP code and return 128 as well. Reproduce code: --------------- define("SOMAXCONN", 2048); echo SOMAXCONN; Expected result: ---------------- Should return 2048 Actual result: -------------- Returns 128 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=49616&edit=1
