Direcoty Indexes

Per ingrandire la colonna del nome del file:

IndexOptions NameWidth=*

Aggiungere un alias per esportare una directory non nella root www:

Alias /_bin "/ciao/_linux_bin/"
<Directory "/ciao/_linux_bin/">
 Options Indexes MultiViews
 AllowOverride None
 Order allow,deny
 Allow from all
</Directory>

IP filters

• Allow

Allow from 192. 

• Deny

Deny from host.domain.com
Deny from 192.168.0.44

• check behavior

Order deny,allow
Deny from all

SSL VirtualHost

• using Gentoo distribution.

1. enable ssl use flag for apache package
2. edit default virtual host for a listening interface and port:

"Listen [::]:443" 
or "Listen 0.0.0.0:443"
or Listen 192.168.82.82:443

1. we want name based virtual hosts

NameVirtualHost *:443

Generating certificate

• replace the "server" name with your domain name of your website.

SRVname=server
cd /etc/ssl/apache2
openssl genrsa 2048 > $SRVname.key
openssl req -new -x509 -nodes -sha1 -days 365 -key $SRVname.key > $SRVname.crt

• Repeat the last step as many virtual hosts you have to serve under an ssl connection, remember to change the SRVname variable in the code:

Virtual host configuration

• example of a basic ssl virtual host:

<VirtualHost *:80>
        ServerName mysslvirtualhost.example.com
        ServerAlias mysslvirtualhost
        Redirect permanent / https://mysslvirtualhost.example.com/
</VirtualHost>

<VirtualHost *:443>

        DirectoryIndex index.php

        SSLEngine on
        SSLCertificateFile /etc/ssl/apache2/server.crt
        SSLCertificateKeyFile /etc/ssl/apache2/server.key

        ServerName mysslvirtualhost.example.com
        ServerAlias mysslvirtualhost

                AllowOverride All
                Order Deny,Allow
                Allow from All
        </Directory>

</VirtualHost>

Proxy

• directives to have into httpd.conf or a virtual host configuration file

• permissions

<Proxy *>
Order deny,allow
Deny from all
Allow from all
</Proxy>

Reverse Proxy

ProxyPass /foo http://foo.example.com/bar
ProxyPassReverse /foo http://foo.example.com/bar

Linux distribution specifics

Gentoo

• vado diretto alla versione 2:
  • file di configurazione;

• Installarlo:

emerge -pvtD apache

controllare le USE flags che ci servono e poi
