There are two ways to install Apache on AIX:
The description below is adapted from IBM Wikis - AIX 5L Wiki - aixopen
Precompiled binaries of Apache for AIX if available from several sources. RPM packages are probably the best choice and are available from several sources:
AIX 5L Open Source Packages Main - Apache lists dependencies for Apache:
By A default AIX 5.3 ML 03 is "Apache-friendly": the the only additional package the Apache requires is libgcc.
rpm -Uvh gcc-4*.rpm rpm -Uvh libgcc-4*rpm
gunzip -c < httpd-2.2.8.tar.gz | tar xvf -
Compilation with LDAP libraries
Or in a single line
./configure -C --enable-so --enable-info --prefix /usr/local/apache2 -with-ldap=yes --enable-ldap=static --enable-authnz-ldap=static
auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile
authz_host authz_owner authz_user autoindex cache dav dav_fs dav_lock deflate dir disk_cache env expires
ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation
rewrite setenvif speling status unique_id userdir usertrack vhost_alias proxy"
# default disabled modules:
# -asis -auth_digest -authn_dbd -cern_meta -charset_lite -dbd -dumpio -ident -imagemap -log_forensic
# -proxy -proxy_ajp -proxy_balancer -proxy_connect -proxy_ftp -proxy_h
Assuming you have just compiled and installed Apache2+ as in the above section, you need several steps to configure Apache on AIX:
/usr/local/apache2/bin/apachectl -k start
Note: the default web pages directory (/usr/local/apache2/htdocs) is not a good location as you risk filling up the /usr filesystem. this is what I recommend as a minimum of changes to the default Apache configuration:
DocumentRoot "/usr/local/apache2/htdocs" ... <Directory "/usr/local/apache2/htdocs"> ... CustomLog logs/access_log common ... ErrorLog logs/error_log
Below we assume you will use default /usr/local/apache2/htdocs for some quick testing and will set up the alternative filesystem later on but don't forget.
Installing Open Source on AIX systems can be a little .... um .... frustrating and I have just been round that loop with installing Ganglia the excellent Performance Monitoring tool to demonstrate it and actually use it too on my own servers. The hard bit is that for every Open Source program, that you want to install, there is 10 to 20 prerequisite packages that you need to install first and you go round this the loop four times as the prerequisites have prerequisites .... This has got known as the "RPM dependencies form hell" problem.
So here is what to do: Download the AIX Toolbox version of wget as this version has no prerequisites - phew! This will act as our RPM fetching tool.
- This is on the IBM website called AIX Toolbox for Linux Applications - which is a poor name is so many ways. Let us call it historic!
- Browse to http
://w ww.i bm.c om/s yste ms/p ower /sof twar e/ai x/li nux/ tool box/ alph a.ht m l
- Search for wget
- Click the RPM link (assuming your lawyer approves)
- And it downloads the file: wget
-1.9 .1-1 .aix 5.1. ppc. rp m
- Move this to your repository or home AIX machine on which you can as root install this package.
- Run: rpm -Uvh wget
-1.9 .1-1 .aix 5.1. ppc. rp m
- I am assuming you have a recent AIX (AIX 6 TL7 or AIX 7 TL1 with service packs or later) and a Internet connection.
- This is an old wget version but that is outweighed by the fact it is statically linked and has no prerequisites that are not already in AIX.
Now the excellent techie Michael Perzl (who works hard on behalf of all AIX people wanting up to date Open Source packages) has come up with a way to list dependencies so you can download them all quickly (with wget) and then simply run one rpm command to install them all. He also compiles 100's of Open Source packages for us all and makes them available from his personal website. You can read more about this at Michael's website http
://wand from here you can get the FTP list of dependency files. ww.p erzl .org /aix /ind ex.p hp?n =FAQ s.FA Qs#r pm-d epen denc y-he l l
Note: The below websites are not from IBM and IBM takes no responsibility for them
In the below we use, as an example, the Apache 2.4 webserver. When writing this Apache 2.4.3 is the latest version - that will change with time.
- Find the dependencies file for Apache 2.4
- Browse to http
://w(this is for AIX 7.1 - for AIX 6.1 it end in 61) ww.o ss4a ix.o rg/d ownl oad/ rpmd b/de plis ts/a ix71 /
- Search for httpd - that is the package name for Apache (it is historic too).
- Download the dependency list file: http
d-2.- if you do this on your workstation, copy the .deps file to your AIX machine in a new directory or as it is small you can even cut'n'paste it in to your AIX terminal emulation window like Putty. 4.3- 1.ai x5.1 .ppc .dep s
- Download Apache and everything it needs using wget
- Apache with: wget ftp:
//ww w.os s4ai x.or g/ev eryt hing /RPM S /htt pd-2 .4.3 -1.a ix5. 1.pp c.rp m
- Prerequisites with: wget -B ftp:
//ww w.os s4ai x.or g/ev eryt hing /RPM S/ -i http d-2. 4.3- 1.ai x5.1 .ppc .dep s
- this reads the .deps file for all the files to download
- Install Apache and everything it needs:
- rpm -Uvh *.rpm
Job done - Michael, you are a genius.
For Ganglia, I did the same for adding other things it needs:
- PHP support into Apache (mod
_php _ap2 4-5. 4.13 -1.a ix5. 1.pp c.rp m) and
- rrdtool (rrd
tool -1.2 .30- 3.ai x5.1 .ppc .rpm )
For Ganglia itself - it is back to Michael Perzl's website http
://wHe has it compiled for AIX and actually developed all the POWER / AIX & Linux add-ons for Ganglia and has them ready for downloading and installing - perhaps more of that in another blog. ww.p erzl .or g

ISTR a problem with libtool on AIX where the relinkde/installed
version of apr-util has a hard-coded reference to expat that cannot be
overridden by LIBPATH. This should only affect running the Apache code
on a different system, as the hard-coded path ought to at least be
You might want to try temporarily using the apr-util libs from
srclib/apr-util/.libs/ instead of the ones re-linked by libtool, and
see if it helps at all.
You might also want to try picking up a newer libtool and re-building.

seems to be the root of all evil. Maybe a wrongly set LIBPATH or missing library at all? There is a library libpthread.so in AIX 5.3, but you seem to need an equivalent library for the gcc compiler.

This build was accomplished on AIX 5.3 ML 03 with no IBM compilers installed. I highly recommend building and installing Apache 2 and PHP 5.1 together. Performing these separately can have unpredicted results.

- Install PHP with the following two commands# cp .libs/libphp5.so /usr/local/apache2/modulesConfiguring Apache2 with PHP
# cp php.ini-recommended /usr/local/apache2/conf/php.ini
- Stop Apache2
# /usr/local/apache2/bin/apachectl -k stop
- Edit /usr/local/apache2/conf/httpd.conf, adding the following at the end
LoadModule php5_module modules/libphp5.so
AddType application/x-httpd-php .php
- Edit the /usr/local/apache2/conf/php.ini file
Change the php variable:
to reflect your timezone
- Restart Apache2
# /usr/local/apache2/bin/apachectl -k start
- Now test PHP with Apache2
