apache is a powerful web server. apache serves html/css/cgi/pl out of the box, and other languages/frameworks via extensions.
root # emerge apache
Many packages have apache2 use flags, and require them to be supported by apache. Setting a system wide apache2 use flag is a good idea.
/etc/portage/make.conf- set system wide apache2 useflag
Apache's configuration files are broken up and located in several spots.
conf.d controls the init script, adding things to it such as -D SECURITY & -D PHP5 will enable web application fire-walling & the php scripting language.
httpd.conf controls how the server behaves, at the bottom of the file it has directives to include configuration files ending in .conf in /etc/apache2/modules.d & /etc/apache2/vhosts.d
To start apache immediately:
root # rc-service apache2 start
To start apache upon boot:
root # rc-update add apache2
mod_rewrite has a reputation of being difficult to set up. mod_rewrite requires following symlinks & Order allow,deny (apache 2.2) or Require all granted (apache 2.4) is set. To test functionality of mod_rewrite we will need to make a few files.
If you want to test this for web applications such as mediawiki adjust the path to /var/www/localhost/htdocs/mediawiki/.htaccess & so on
/var/www/localhost/htdocs/.htaccess- enable the rewrite engine
RewriteEngine on RewriteRule ^test.html$ rewrite.html
/var/www/localhost/htdocs/test.html- set system wide apache2 useflag
rewrite is not working
/var/www/localhost/htdocs/rewrite.html- set system wide apache2 useflag
rewrite is working
Then point your browser @ http://127.0.0.1/test.html the text from rewrite.html should be loaded.
