Using htpasswd

Creating new file for user

$ htpasswd -c /path/to/passwordfile username

Add or change password for user

$ htpasswd /path/to/passwordfile username

Enable server status in Ubuntu

Enable mod_status module

$ sudo a2enmod status

Enable mod_deflate in Ubuntu

The mod_deflate module provides the DEFLATE output filter that allows output from your server to be compressed before being sent to the client over the network

To enable:

$ sudo a2enmod deflate

To enable manually, edit httpd.conf

LoadModule deflate_module /usr/lib/apache2/modules/mod_deflate.so

<IfModule mod_deflate.c>
    # these are known to be safe with MSIE 6
    AddOutputFilterByType DEFLATE text/html text/plain text/xml

    # everything else may cause problems with MSIE 6
    AddOutputFilterByType DEFLATE text/css
    AddOutputFilterByType DEFLATE application/x-javascript application/javascript application/ecmascript
    AddOutputFilterByType DEFLATE application/rss+xml
</IfModule>

Running Apache with a different user/group

Edit httpd.conf

User username
Group groupname

In Ubuntu this is set in /etc/apache2/apache2.conf as:

User ${APACHE_RUN_USER}
Group ${APACHE_RUN_GROUP}

where ${APACHE_RUN_USER} and ${APACHE_RUN_GROUP} is defined in /etc/apache2/envvars
