Web Server How-To (Apache2 + mod_php + mysql)

khel · Tux's lil' helper Joined: 07 Mar 2003 Posts: 80

I couldn't find any step-by-step instructions on setting up a webserver, so, after lurking on this forum for a while, I decided to share my experience on the subject. Anyway, to make the long story short, that's what I did to make Apache2/mod_php/mysql combo work to suite my needs :-)

edit /etc/make.conf and add
ACCEPT_KEYWORDS="~x86"
USE="-X -gtk -gnome -alsa -qt -qtmt -pdflib mysql apache2 pam ssl"

and don't forget to run env-update after changing the make.conf :-)

emerge mysql
rc-update add mysqld default
emerge netpbm (image manipulation package required by Gallery)

emerge apache
rc-update add apache2 default

then
emerge mod_php
emerge clean

edit /etc/conf.d/apache2 and add this line
APACHE_OPTS="-D SSL -D PHP4"

edit /etc/apache2/conf/apache2.conf and add this line
LoadModule php4_module /usr/lib/apache2-extramodules/libphp4.so

then restart apache

/etc/init.d/apache2 -k restart

p.s. If you change "DocumentRoot" in apache2.conf, you'll need to change it in commonapahche2.conf as well.
Look for

###This should be changed to whatever you set Document root to.
###
<Directory /home/httpd/htdocs>

And in /etc/apache2/conf/modules.d/41_mod_ssl.default-vhost.conf for SSL to work

So far it works just fine for me, but time will show how stable and bug free it is :-)

If you have any comment/suggestions - feel free to post :-)

I hope this will be useful at leas to somebody.

kind of hard to write a specific guide for a webserver ... for example i just emerge apache dont usually have a mysql backend sometimes emerge php if its needed

i would go without xinetd and emerge mysql before (!) apache - also make sure that the useflags for mysql, apache2, php and the like are correct - its difficult to write a gentoo specific doc for this - as people set up their servers very differently depending on their needs...

Just updated my original post. I hope it makes a little bit more sense now :-)

... and following your example, decided to try running my system without xinetd (habits are so difficult to change :-)

).
Thanks

Thanks I found this useful since I'm considering re-doing my gentoo machine. It's still on the old GCC 2.9.something...that's another story. As of now I didn't use emerge to install all these things, this would help a lot.

Would there be anything different if one was to use the latest stable version of apache instead of apache 2?

I've tried to follow this except using the latest (1.3.27) version of apache. Here's the result:

My ssl and php are not working, apache (with the exception of those two) is.

There's no real difference between that and these instructions except for these 2 lines

# ebuild /var/db/pkg/dev-php/mod_php-4.2.2-r1/mod_php-4.2.2-r1.ebuild config
# ebuild /var/db/pkg/net-www/mod_ssl-2.8.10/mod_ssl-2.8.10.ebuild config

these print and you're instructed to do them after you emerge each mod_php and mod_ssl anyway :\

I gave up and decided to use apache 2

although I can't get ssl working right and when I tried to turn it on in the phpBB (what I'm using the webserver+database for) I totally messed it up, whatever I'll figure it out all in due time

I've found I need to add -java to my USE to get mod_php to work correctly. If I don't have it there I get an error on configure.

tgoodaire · Posted: Mon Mar 17, 2003 7:39 am Post subject: xinetd

I like using xinetd for everything for several reasons. It starts and stops my servers for me as they are needed, so they're not sitting there taking up my RAM when they're rarely used. Also, there is much better access control and logging than what's in most standalone servers. It's not too hard to configure either. If you can figure out how to configure apache, xinetd should be a breeze.

I am an newbie to gentoo.
I want to install apache 2.0.45

I am using 1.4.rc3

Though my USE='apache2"
Whenever I am doing emrge apache it installs apache 1.3.27.r3

If simply emerge /usr/portage/../apache 2.0.45 then after the installation it says apachectl not found

As a result I have to first installed apache 1.3 and apache 2
After this emerge mod_php and edit apache to -D PHP as perthe instruction on the screen. But PHP does not work.

Please help

Hi All,

I have emerged apache2 and php4. I have checked the steps as outlined by khel in the first post and all seems ok.

I have my php .so file in /etc/apache2/extramodules.

When I run apache2 start I get the following error

Syntax error on line 57 of /etc/apache2/conf/apache2.conf:
Cannot load /etc/apache2/extramodules/libphp4.so into server: libpq.so.2: cannot open shared object file: No such file or dir

How do I fix this? I know it may be simple to some of you but I am struggling a bit. I need to get to know php/apache/postgres to get a piece of software I want to evaluate, i.e tutos, working.

Thanks
Mark

Edit ****** Ok I have found a libpq.so.3 on my system. How do I edit php4 to use this instead of the .2 version?

I think

APACHE_OPTS="-D SSL -D PHP4"

should be

APACHE2_OPTS="-D SSL -D PHP4"

d0wn_under

I get the same problem with apache 1.3.27-r3...

* Starting apache...
Syntax error on line 21 of /etc/apache/conf/apache.conf:
Cannot load /etc/apache/extramodules/libphp4.so into server: libpq.so.2: cannot open shared object file: No such file or directory [ !! ]

For a similar, but different problem, some people have suggested doing the following

export LDFLAGS='-lstdc++'
emerge sablotron

but it didn't work for me. apache does work if I take out php4 from the config files, but that doesn't help

Anyone any ideas?

Robin

I tried so many combinations of stuff to get apache 1.3 working, with no luck. used this tutorial for apache2 which helped a lot, thanks

For me it didn't work first time, I had to make these changes:

-java in USE, otherwise apache wouldn't compile

these 4 lines in /etc/apache2/conf/apache2.conf:

LoadModule php4_module /usr/lib/apache2-extramodules/libphp4.so
LoadModule ssl_module /usr/lib/apache2-extramodules/mod_ssl.so
Include conf/modules.d/40_mod_ssl.conf
Include conf/modules.d/41_mod_ssl.default-vhost.conf
