Compile httpd 2.4.6-P1

Introduction to Apache HTTPD

The Apache HTTPD package contains an open-source HTTP server. It is useful for creating local intranet web sites or running huge web serving operations.
This package is known to build and work properly using an LFS-7.4 platform.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/apache

Installation of Apache HTTPD

For security reasons, running the server as an unprivileged user and group is strongly encouraged. Create the following group and user using the following commands as root:
groupadd -g 25 apache &&
useradd -c "Apache Server" -d /srv/www -g apache \
        -s /bin/false -u 25 apache
Build and install Apache HTTPD by running the following commands:
patch -Np1 -i ../httpd-2.4.6-blfs_layout-1.patch &&
./configure --enable-layout=BLFS                            \
            --enable-mods-shared="all cgi"                  \
            --enable-mpms-shared=all                        \
            --with-apr=/usr/bin/apr-1-config                \
            --with-apr-util=/usr/bin/apu-1-config           \
            --enable-suexec=shared                          \
            --with-suexec-bin=/usr/lib/httpd/suexec         \
            --with-suexec-docroot=/srv/www                  \
            --with-suexec-caller=apache                     \
            --with-suexec-userdir=public_html               \
            --with-suexec-logfile=/var/log/httpd/suexec.log \
            --with-suexec-uidmin=100 &&
make
This package does not come with a test suite.
Now, as the root user:
make install                                 &&

mv -v /usr/sbin/suexec /usr/lib/httpd/suexec &&
chgrp apache           /usr/lib/httpd/suexec &&
chmod 4754             /usr/lib/httpd/suexec &&

chown -v -R apache:apache /srv/www

Command Explanations

--enable-mods-shared="all cgi": The modules should be compiled and used as Dynamic Shared Objects (DSOs) so they can be included and excluded from the server using the run-time configuration directives.
--enable-mpm-shared=all: This switch ensures that all MPM (Multi Processing Modules) are built as Dynamic Shared Objects (DSOs), so the user can choose which one to use at runtime.
--enable-suexec: This switch enables building of the Apache suEXEC module which can be used to allow users to run CGI and SSI scripts under user IDs different from the user ID of the calling web server.
--with-suexec-*: These switches control suEXEC module behavior, such as default document root, minimal UID that can be used to run the script under the suEXEC. Please note that with minimal UID 100, you can't run CGI or SSI scripts under suEXEC as the apache user.
... /usr/lib/httpd/suexec: These commands put suexec wrapper into proper location, since it is not meant to be run directly. They also adjust proper permissions of the binary, making it setgid apache.
chown -R apache:apache /srv/www: By default, the installation process installs files (documentation, error messages, default icons, etc.) with the ownership of the user that extracted the files from the tar file. If you want to change the ownership to another user, you should do so at this point. The only requirement is that the document directories need to be accessible by the httpd process with (r-x) permissions and files need to be readable (r--) by theapache user.

Configuring Apache

Config Files

/etc/httpd/httpd.conf and /etc/httpd/extra/*

Configuration Information

See /usr/share/httpd/manual/configuring.html for detailed instructions on customising your Apache HTTP server configuration file.

Boot Script

If you want the Apache server to start automatically when the system is booted, install the /etc/rc.d/init.d/httpd init script included in the blfs-bootscripts-20131023 package.
make install-httpd

Contents

Installed Programs:ab, apachectl, apxs, checkgid, dbmmanage, fcgistarter, htcacheclean, htdbm, htdigest, htpasswd, httpd, httxt2dbm, logresolve, and rotatelogs
Installed Libraries:None
Installed Directories:/etc/httpd, /srv/www, /usr/include/httpd, /usr/lib/httpd, /usr/share/httpd /var/log/httpd, and /var/run/httpd

Short Descriptions

ab
is a tool for benchmarking your Apache HTTP server.
apachectl
is a front end to the Apache HTTP server which is designed to help the administrator control the functioning of the Apachehttpd daemon.
apxs
is a tool for building and installing extension modules for the Apache HTTP server.
checkgid
is a program that checks whether it can setgid to the group specified. This is to see if it is a valid group for Apache2 to use at runtime. If the user (should be run as superuser) is in that group, or can setgid to it, it will return 0.
dbmmanage
is used to create and update the DBM format files used to store usernames and passwords for basic authentication of HTTP users.
htcacheclean
is used to clean up the disk cache.
htdbm
is used to manipulate the DBM password databases.
htdigest
is used to create and update the flat-files used to store usernames, realms and passwords for digest authentication of HTTP users.
htpasswd
is used to create and update the flat-files used to store usernames and passwords for basic authentication of HTTP users.
httpd
is the Apache HTTP server program.
httxt2dbm
is used to generate DBM files from text, for use in RewriteMap.
logresolve
is a post-processing program to resolve IP-addresses in Apache's access log files.
rotatelogs
is a simple program for use in conjunction with Apache's piped log file feature.
