Web Server for linux.
Paths:
/etc/apache2/sites-available

/etc/apache2/sites-enabled (symbolic links to sites-available/*.conf files)

sudo apache2ctl -t -D DUMP_VHOSTS
sudo apache2ctl configtest
sudo a2enmod ssl

Virtual Hosts

Apache allows to have multiple web sites on the same server. To do this go to sites-available and create a
.conf file for each host you whant containing the following:

 <VirtualHost *:80>
    ServerAdmin rafael@herrerosolis.com
    DocumentRoot /var/www/webfolder
    ServerName www.yourwebpagename.com
    ServerAlias www.yourwebpagename.com

    ErrorLog /var/www/yourwebfolder/logs/error.log
    
    # Posible values include: debug, info, notice, warn, error, crit.
    # alert, emerg.

    CustomLog /var/www/yourwebfolder/logs/access.log combined

 </VirtualHost>

You should also enter in your domain administration panel and create the CNAMES to redirect trafic
to the public ip of this server

Basic SSL VirtualHost:

<VirtualHost *:80> 
    ServerName home.rra.lan 
    ServerAdmin webmaster@rra.lan 
    DocumentRoot /var/www/home.rra.lan 
    Redirect permanent / https://home.rra.lan 
    ErrorLog ${APACHE_LOG_DIR}/error.log 
    CustomLog ${APACHE_LOG_DIR}/access.log combined 
</VirtualHost> 
<VirtualHost *:443> 
    ServerName home.rra.lan 
    ServerAdmin webmaster@rra.lan 
    DocumentRoot /var/www/home.rra.lan 
    ErrorLog ${APACHE_LOG_DIR}/error.log 
    CustomLog ${APACHE_LOG_DIR}/access.log combined 
    SSLEngine on 
    SSLCertificateKeyFile /etc/ssl/private/home.rra.lan.key 
    SSLCertificateFile /etc/ssl/certs/home.rra.lan.crt 
    SSLCertificateChainFile /etc/ssl/certs/FreeIPA-CA.crt 
</VirtualHost>

Redirect HTTP to HTTPS

sudo a2enmod rewrite

sudo nano /etc/apache2/sites-available/redirect_HTTP_to_HTTPS.conf

<VirtualHost *:80>
    RewriteEngine on
    RewriteCond %{HTTPS} !=on
    RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,QSA,R=permanent]

    ErrorLog ${APACHE_LOG_DIR}/error.log                                                             
    CustomLog ${APACHE_LOG_DIR}/access.log combined 
</VirtualHost>

sudo ln -s /etc/apache2/sites-available/redirect_HTTP_to_HTTPS.conf /etc/apache2/sites-enable/redirect_HTTP_to_HTTPS.conf

Authentication

Create user account with:

htpasswd -c /usr/local/apache/passwd/passwords rbowen

Protect with the directory directive:

<Directory "/usr/local/apache/htdocs/secret">
            AuthType Basic
            AuthName "Restricted Files"
            # (Following line optional)
            AuthBasicProvider file
            AuthUserFile "/usr/local/apache/passwd/passwords"
            # Require user rbowen
            Require valid-user
        </Directory>

Reverse Proxy

a2enmod proxy proxy_http  # HTTP
a2enmod proxy proxy_ftp   # FTP
a2enmod proxy proxy_html  # rewrite HTML links in proxy address space
a2enmod proxy proxy_ajp   # Tomcat
a2enmod proxy
a2enmod rewrite
a2enmod deflate
a2enmod headers
a2enmod proxy_balancer
a2enmod proxy_connect

VirtualHost ProxyPass

<IfModule mod_ssl.c>
        <VirtualHost *:443>
                ServerAdmin webmaster@rra.lan
                ServerName splunk.rra.lan

                ErrorLog ${APACHE_LOG_DIR}/error.log
                CustomLog ${APACHE_LOG_DIR}/access.log combined
                ServerAlias splunk.rra.lan
                SSLEngine on
                SSLCertificateFile      /etc/ssl/certs/splunk.rra.lan.crt
                SSLCertificateKeyFile /etc/ssl/private/splunk.rra.lan.key

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

                ProxyRequests Off
                ProxyPreserveHost On
                # SSLProxyEngine on
                ProxyPass / http://0.0.0.0:8000/
                ProxyPassReverse / http://0.0.0.0:8000/
