Installation of Apache HTTPD

转载链接：http://www.linuxfromscratch.org/blfs/view/svn/server/apache.html

Installation of Apache-2.4.7 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 asroot:

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-2.4.7-blfs_layout-1.patch &&
sed '/dir.*CFG_PREFIX/s@^@#@' -i support/apxs.in &&
./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

sed '/dir.*CFG_PREFIX/s@^@#@'...: Forces theapxs utility to use absolute pathnames for modules, when instructed to do so.

--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 theApache 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 putsuexec wrapper into proper location, since it is not meant to be run directly. They also adjust proper permissions of the binary, making it setgidapache.

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 thehttpd 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 yourApache 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

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 theApache httpd 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.
