 +====== Gentoo Linux: Apache ======
 +
 +  * [[Apache]]
 +  * [[Apache Worker MPM PHP CGI Suexec Setup]]
 +  * [[Gentoo]]
 +
 +Running Apache on Gentoo gives you a lot of flexibility.  However, out of the box, there are a lot of modules that are not used in many client configurations.
 +==== Modules ====
 +
 +The modules that Apache is built with can be set by ''APACHE2_MODULES'' in ''/etc/make.conf''.
 +
 +Here is a trimmed down version that removes many unused modules.
 +
 +<code>
 +APACHE2_MODULES="actions alias auth_basic authn_default auth_digest authn_file authz_default
 +authz_host authz_user autoindex cache cgi cgid deflate dir disk_cache env expires file_cache
 +filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite
 +setenvif status unique_id userdir vhost_alias"
 +</code>
 +
 +==== MPMS ====
 +
 +Gentoo lets you configure the MPM in use.  The most common ones are ''prefork'' and ''worker'', with ''prefork'' being the default.  You can change this in ''make.conf''.
 +
 +<code>APACHE2_MPMS="worker"</code>
 +
 +==== Optimization ====
 +
 +You can build Apache, or any program, with different settings than used by ''make.conf'' Apache is a good candidate, since it is a primary application in the LAMP stack.
 +
 +An optimized version using gcc with highest optimizations:
 +
 +<code>mkdir -p /etc/portage/env/www-servers</code>
 +
 +Edit ''apache'' file in that directory and add this:
 +
 +<code>CFLAGS="-O3 -pipe -march=native"
 +CXXFLAGS="${CFLAGS}"</code>
