Kernel Compiling
Dec 24, 2008I've never actually compiled a kernel before, and wanted to know the basics when it comes to compiling for a standard CPanel/Centos 32bit system.

Compiling RHE 5 Kernel
Apr 26, 2008I have always used RPM kernels from the RedHat Network, in this time I need to compile an SMP kernel in a server that is used to serve common webhosting traffic (web, ftp, email, etc) with cPanel.
I have compiled kernels from source in desktops stations, but never in remote servers.. do you have any recommendations to do this at a Dual Xeon 3.2 RHE 5 + cPanel server? Oh.. almost forgot.. I will also compile it with GRsecurity.
Should I use a src kernel from RedHat, or a kernel.org latest kernel?
[kernel: Kernel BUG At Mm/rmap.c:479] Any Idea What This Is?
Mar 29, 2007we have one box in hivelocity.net that has been down so many times this month that we were forced to remove links to siteuptime where we were once so proud of having a 99.7% uptime for 3 years in theplanet.
syslog shows that just before crashing, these entries were made:
kernel: kernel BUG at mm/rmap.c:479
kernel: invalid operand:0000 [#1]
dmesg also shows this:
...
Brought up 2 CPUs
zapping low mappings.
checking if image is initramfs... it is
Freeing initrd memory: 482k freed
NET: Registered protocol family 16
PCI: PCI BIOS revision 2.10 entry at 0xf9f20, last bus=1
PCI: Using configuration type 1
mtrr: v2.0 (20020519)
mtrr: your CPUs had inconsistent fixed MTRR settings
mtrr: probably your BIOS does not setup all CPUs.
mtrr: corrected configuration.
...
i've googled these messages and they point to ram problems.
hivelocity.net claims to have done diagnostics on the box and that there were no problems reported.
they said this is a result of a sys configuration problem made by us.
any ideas?
Kernel Headers For Virtuozzo Kernel
May 20, 2009running centos/virtuozzo 2.6.18-028stab062.3
when i configure vmware it asks at one point for kernel header files. where would i find them to match the current kernel?
i asked at parallels forums but help there is very scarce. i checked openVZ repositories and they dont yet have headers for this version.
what are my options? i have one last windows machine left and want to run it in VMware.
Centos + Kernel 2.6.9-34.0.2- How To Upgrade Kernel
Apr 29, 2007Last year I ordered a new server with Centos 4.3 and it had the kernel kernel 2.6.9-34.0.2ELsmp installed. It runned fine and I didn't update any packages since then.
Today I started getting a problem where both mysqld and kswapd0 uses very high amounts of CPU, spiking up to 100% and my memory usage is at 99% all the time. The problem seems exactly the same as the one mentioned in this thread.
In that thread the exact same kernel is said to be insecure and to cause this problem. I also came across a centOS bug that reports this problem with high cpu, mem usage and mysql & kswapd0 consuming all resources.
In the linked thread the person solved the problem by upgrading to kernel 2.6.9-42 using rpms but others recommended a newer kernel or a custom compiled kernel for CentOS.
Apparently when they used yum it said 34.0.2 was the latest kernel.
What should I do to upgrade the kernel, which version should i upgrade to, and where do I get it from? I won't be able to compile a custom kernel and I've only installed basic rpm packages before.
Re-Compiling PHP
Aug 7, 2007I was recently faced with a problem, i had to install some extensions which were not included by default with php (libcurl being one of them). I didn't have a clue what to do, but because my dedicated server is running debian, i had to force myself to learn.
Anyway, back to the point. I already have php5 running (but it needs to be re-compiled) and i have downloaded libcurl. I used apt-get install php5-curl and that took care of it. The questions are:
To recompile do i need to remove the old installation of PHP before compiling it again to add the extensions?
Do i need enable the extensions like mysql and stuff or do they install as default if not specified, im guessing i would need to specify everything?
Im used to downloading a pre compiled package, running the installer and away we go, actually its MAMP on OSX. I remember in windows you could just add the extension in the .ini i later learned in OSX and Linux its not as easy.
Compiling Php On Centos 5.3

Compiling PHP Error
Mar 21, 2008I recently tried upgrading my test VPS to run PHP 6.0, and it worked.
However I wasn't able to get MySQL to compile with PHP.
Hence I just reinstalled MySQL and tried recompiling PHP (from source) again. However I still get errors when compiling PHP:
checking for MySQL support... yes
checking for specified location of the MySQL UNIX socket... no
checking for MySQL UNIX socket location... /var/tmp/mysql.sock
configure: error: Cannot find libmysqlclient under /usr/local.
Note that the MySQL client library is not bundled anymore!
No matter what ./configure command I run, I can't seem to get this working. For example, the PHP INSTALL documentation (comes with the source files) actually says running:
./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql
Will work fine. However it doesn't. I've also tried specifying the MySQL directory, to no success.
Just as some extra information, libmysqlclient is at:
-bash-3.00# find /usr -name libmysqlclient*
/usr/lib/libmysqlclient.so.6
/usr/lib64/libmysqlclient.so
/usr/lib64/libmysqlclient.so.14
/usr/lib64/libmysqlclient_r.so
/usr/lib64/mysql/libmysqlclient.a
/usr/lib64/mysql/libmysqlclient.la
/usr/lib64/mysql/libmysqlclient_r.a
/usr/lib64/mysql/libmysqlclient_r.la
/usr/lib64/mysql/libmysqlclient.so
/usr/lib64/mysql/libmysqlclient_r.so
/usr/lib64/libmysqlclient.so.15
/usr/lib64/libmysqlclient.so.15.0.0
/usr/lib64/libmysqlclient_r.so.15
/usr/lib64/libmysqlclient_r.so.15.0.0
/usr/local/lib64/libmysqlclient.so.14
/usr/local/cpanel/lib64/libmysqlclient.so.14
However specifying the MySQL directories as "/usr/lib64, /usr/bin, /usr/lib64/mysql, /usr/local/lib64 or /usr/lib" doesn't seem to work.
The complete configure command I've tried running is: "./configure --with-apxs2=/usr/local/apache/bin/apxs --prefix=/usr/local/ --with-icu-dir=/usr/local/icu --with-pspell --with-mysql"

Compiling W/ CFLAGS=-O2
May 2, 2007Usually when I compile my scripts from source I never use any compiler flags. After taking a look at this article I found
[url]
I noticed that they were using the CFLAGS=-O2 option. Is this compatible for fedora core and/or centOS? Do all gcc compilers have this feature, and if they do, is it safe?
Should I use it or should I avoid it?
Compiling PHP Zip Extension Onto A Mac That Has MAMP Pro
Mar 10, 2008compiling the zip extension for my MAMP installation. I used this tutorial here (using phpize):
[url]
All is well.. but when I run make test it gives me this:
Warning: PHP Startup: Invalid library (maybe not a PHP library) 'zip.so' in Unknown on line 0
Warning: PHP Startup: Unable to load dynamic library 'modules/imap.so' - (null) in Unknown on line 0

Warning: PHP Startup: Invalid library (maybe not a PHP library) 'zip.so' in Unknown on line 0
Warning: PHP Startup: Invalid library (maybe not a PHP library) 'zip.so' in Unknown on line 0
So, from what I see there are two problems:
1. compiling the zip.so fails...
2. Some directories are wrongly set, because my extension .so files reside in /mamp/bin/php5/lib/php/extensions/no-debug-non-zts-20050922/
I see no "modules" in there, so..
Compiling The Zip Library On MAMP

Compiling Static Standalone PHP Binary
Jun 22, 2007I am using the following configure command in hope to generate a PHP binary which is totally independent, standalone and can be moved to other systems without caring for dependencies:
./configure --enable-fastcgi --enable-force-cgi-redirect --enable-discard-path --prefix=/server/php --exec-prefix=/server/php --with-config-file-path=/server/php --disable-all --enable-shared=no --enable-static=yes --enable-session --with-gd --with-zlib-dir --with-freetype-dir --enable-sockets
But when I try to run the generated binary on another system which doesn't have freetype etc installed, I get the following error:
error while loading shared libraries: libfreetype.so.6
Compiling Apache Module Error
Jan 28, 2007I have recently installed the latest version of apache which is version 2.2.4 and it seems many modules were left out so I decided to add one of my favorite modules myself
I have DirectAdmin install so here is what I did
I edited this file: configure.apache_2
and at the end of the file added --enable-expires
After adding normally we would recompile apache I was doing that and I got this error
Code:
/usr/local/directadmin/customapache/configure.apache_2: line 24: --enable-expires: command not found
*** There was an error while trying to configure Apache 2. Check the configure.apache_2 file
Not sure what I'm doing wrong if someone could help me I would be greatful.

Compiling Apache/PHP/Mysql Under X86_64
Feb 9, 2007I'm wondering if there are special notes on compiling sever softwares under x86_64 (CentOS 4.4 64bit, Pentium D)? Are there any specific flags for extra optimizations? Or the regular "./configure" will compile things in x86_64 by default?

Compiling PHP5 With Mysql & Mysqli Support
Jun 15, 2009While trying to compile PHP 5 with mysql and mysqli , I was facing some issues.
Actually, the configure command generates a bad Makefile.
Open the Makefile and look for a line staring with EXTRA_LIBS
You will see that the option “-lmysqlclient” is repeated twice. Delete one of them and save the Makefile.
Now, you should be able to run the Make command and compile PHP without any issues.
Compiling Mod_security With PCRE (significant Performance Increase)
Jan 27, 2007From the ModSecurity manual:
Quote:
By default ModSecurity relies on the regular expression library built into Apache for pattern matching.
This works well with Apache 2.x but not so much with Apache 1.x. The Apache 1.x regular expression
engine is several times slower. Since 1.9.2 it is possible to compile ModSecurity for Apache 1.x against
an external regular expression library (PCRE, [url] the same library used in Apache 2.x)
and achieve significant performance increase. This is achieved with the USE_PCRE compile-time flag.
If you have PCRE already installed on your system it may be sufficient to compile ModSecurity like this:
Code:
# <apache1-home>/bin/apxs -DUSE_PCRE -cia mod_security.c
Ok, so I tried and got this error:
Code:
[root@servidor1 customapache]# apxs -DUSE_PCRE -cia mod_security.c
gcc -DLINUX=22 -DHAVE_SET_DUMPABLE -I/usr/include/gdbm -DMOD_SSL=208128 -DUSE_HSREGEX -DEAPI -fpic -DSHARED_MODULE -I/usr/include/apache -DUS
E_PCRE -c mod_security.c
mod_security.c:37:18: pcre.h: No such file or directory
mod_security.c: In function `my_pregcomp':
mod_security.c:929: error: `PCRE_CASELESS' undeclared (first use in this function)

mod_security.c: In function `my_regexec':
mod_security.c:940: error: `PCRE_ERROR_NOMATCH' undeclared (first use in this function)
apxs:Break: Command failed with rc=1
I double checked if I have PCRE installed:
Code:
[root@servidor1 customapache]# yum search pcre
pcre.i386 4.5-3.2.RHEL4 installed
Matched from:
pcre
Perl-compatible regular expression library.
PCRE has its own native API, but a set of "wrapper" functions that are based on
the POSIX API are also supplied in the library libpcreposix. Note that this
just provides a POSIX calling interface to PCRE: the regular expressions
themselves still follow Perl syntax and semantics. The header file
for the POSIX-style functions is called pcreposix.h.
[url]
And I even located the /lib/libpcre.so.0.0.1 and copied it to /usr/lib/apache/libpcre.so, with no sucess. Got the same error.
Has anyone sucessfully compiled mod_security with PCRE and can help me?

Xen Kernel
Apr 4, 2009I have a Xen VPS. I started with a Debian 4 image and have since upgraded to Debian 5. Firstly was this advisable? Secondly what Kernel version should I be running, or rather is it set by my installation or by the Xen server?

Apr 24, 2009as part of a project I have lately been looking into various aspects of kernel tuning. Most notably lately tuning the TCP stack for more efficient memory usage/throughput.
Thought I would start this thread to mention some of the tools I'd found for doing testing and see what anyone else had to recommend.
So far my favorite of the bunch is nuttcp. Its easy to use and gives a very good idea of how much of your bandwidth you are able to utilize.
A few interesting web pages are as follows for anyone interested in the topic:
[url]- Tuning TCP for High Bandwidth Delay networks
[url]- TCP Tuning Cook book, some interesting information in there as well
[url]...formanceTuning - Performance Tuning TWiki. Has a list of useful tools, flags for existing tools and ways to monitor network performance from a system level, along with some suggestions of things to correct
