Minimal Apache Configuration

Posted Jan 2 2015, 04:17 by William Shallum [updated Jul 5 2015, 08:18]

The default Apache config file is huge (and heavily commented) compared to e.g. nginx. How small can you make the config file if you just want to get it up?

Here’s what I came up with for Apache 2.4 (note: mime.types not included)

# logs
ErrorLog /dev/stdout

PidFile httpd.pid

# select MPM
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
# must load security module
LoadModule unixd_module modules/mod_unixd.so
# must load authn_core
LoadModule authn_core_module modules/mod_authn_core.so
# and authz_core for "Require all granted"
LoadModule authz_core_module modules/mod_authz_core.so
# to enable index (default index.html)
LoadModule dir_module modules/mod_dir.so
# to enable autoindex
LoadModule autoindex_module modules/mod_autoindex.so
# to load mime types
LoadModule mime_module modules/mod_mime.so
# in case people want to rewrite via .htaccess
LoadModule rewrite_module modules/mod_rewrite.so
Listen [::1]:8000

# dev server does not need lots of spare servers
MaxSpareServers 2
MinSpareServers 1
StartServers 3
# the default for prefork MaxRequestWorkers / MaxClients is 256, should be enough

TypesConfig mime.types

DocumentRoot "/doc/root"
<Directory />
  Require all denied
  AllowOverride None
<Directory "/doc/root">
  Require all granted
  Options +Indexes
  AllowOverride All

The minimal is not so big after all. It is a little annoying that some modules HAVE to be loaded otherwise the server won’t run. I have a script to serve up a local directory here (with optional PHP support): https://github.com/wshallum/serveup
