I have Slackware 10 that come with apache 1.3. However I want to install apache 2. If I install apache 2 in usr prefix ( ./configure --prefix=/usr ), will it collide with apache 1.3???

Thank you.

Someone else would be able to advise you on the collision - however, you could not just use pkgtool to remove apache 1.3.x first? You could then safely install 2.x :)

Use these packages,
http://www.linuxpackages.net/search_...pache&ver=10.0

All you need to do is removepkg the old one(s), and installpkg apache2 (and phpapache2 if you want php).

No, I don't want to remove apache 1.3. I just want to play around with apache 2 and maybe I want to get a work with apache 1.3. So I guess I have to install to another prefix.

Well, there are the packages if you want to install Apache2.

AFAIK, apache 1.x installs to /etc/apache, while apache 2.x installs to /etc/apache2.

But im not sure if there other libraries or links that may conflict with having both installed at the same time... especially the binaries or modules..

it is just the config files that are installed in /etc, not the programs, libraries/modules and documentation.

I have installed apache 2 two years ago, what I did was download apache2 and php sources and compile them with prefix=/opt/apache2 and /opt/php

here were my options used to compile apache2 :
./configure --prefix=/opt/apache2 \
--enable-so \
--enable-access=shared \
--enable-actions=shared \
--enable-alias=shared \
--enable-auth=shared \
--enable-auth_dbm=shared \
--enable-auth_digest=shared \
--enable-cgi=shared \
--enable-cgid=shared \
--enable-dir=shared \
--enable-headers=shared \
--enable-imap=shared \
--enable-include=shared \
--enable-info=shared \
--enable-log_config=shared \
--enable-logio=shared \
--enable-mime=shared \
--enable-mime_magic=shared \
--enable-speling=shared \
--enable-ssl=shared \
--enable-status=shared \
--enable-unique_id=shared \
--enable-usertrack=shared \
--enable-vhost_alias=shared \
--enable-php4=shared

And php :

./configure --prefix=/opt/php \
--with-apxs2=/opt/apache2/bin/apxs \
--with-config-file-path=/opt/php \
--with-curl=/usr/bin/curl \
--enable-sockets \
--enable-ftp

At the time I did it apache2 was version 2.46, but things for configure are surelly the same.
All files were installed in /opt and apache2 running did not collide with apache 1.23.
