How to redirect HTTP to HTTPS using mod_rewrite.

The following configuration will configure Apache to automatically redirect HTTP requests to HTTPS, i.e. http://www.website.com to https://www.website.com.

httpd.conf:

RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^/(.*) https://%{SERVER_NAME}/$1 [L,R]

.htaccess:

RewriteEngine On
RewriteCond %{SERVER_PORT} !^443$
RewriteRule ^(.*) https://%{SERVER_NAME}/$1 [L,R]

Remember, if you put this rule in the main server configuration file (usually httpd.conf) rather than an .htaccess file, you'll need to use "^/" instead of "^" at the beginning of the RewriteRule line. Because of this there are two code snippets above, one for httpd.conf and one for .htaccces.

How do I change the length of the URLs generated by mod_autoindex?

The NameWidth keyword allows you to specify the width of the filename column in bytes.

• -NameWidth (or unset) allows mod_autoindex to calculate the best width.
• NameWidth=n fixes the column width to n bytes wide.
• NameWidth=* grows the column to the necessary width.

Below is an example on how to edit your httpd.conf file to enable unlimited characters:

# IndexOptions: Controls the appearance of server-generated directory
# listings.
#
IndexOptions FancyIndexing VersionSort NameWidth=*

(13)Permission denied: /www/.htaccess pcfg_openfile: unable to check htaccess file, ensure it is readable

This can range in exact location but at the core it is a permissions issue.

• While child directories of the DocumentRoot can have a permission value of 744 the DocumentRoot needs to have a permission of 755.

• Ensure all .htaccess files have a permission of 755

chmod -R 755 <dir_or_file(s)>

Access forbidden! You don't have access to the requested directory...

There is either no index document or the directory is read-protected.

Allow Directory Listing

• Create .htaccess file in the affected directory and copy the text below into the file.

Create DirectoryIndex File

• Determine Allowable DirectoryIndex extensions from the DirectoryIndex line in your httpd.conf file.

• Create an empty file in the affected directory.

touch index.htm

Invalid command 'Order', perhaps misspelled or defined by a module not included in the server configuration

mod_access has changed to authz_host_module. Please load the following module to httpd.conf:

LoadModule authz_host_module modules/mod_authz_host.so

Invalid command 'AuthGroupFile', perhaps misspelled or defined by a module not included in the server configuration

LoadModule authz_groupfile_module modules/mod_authz_groupfile.so

configuration error: couldn't check access. No groups file?: /

LoadModule authz_user_module modules/mod_authz_user.so

Enforce password authentication unless accessing from local network

Add the following lines to your .htaccess file:

AuthUserFile /www/server.com/stuff/htdocs/.htpasswd
AuthGroupFile /dev/null
AuthName "Secrets :)"
AuthType Basic

require valid-user
Allow from 192.168.85.0/24
