Enable .htaccess on Apache HTTPD Server

Tuesday, October 20th, 2009

Occasionally, there becomes a need to expose the use of the .htaccess file to the domains hosted on your Apache server. This technique is particularly useful when you host websites for external clients (or developers).

The steps to enable it are relatively easy,

  • Uncomment the ‘httpd.conf’ line that reads as:

    LoadModule rewrite_module modules/mod_rewrite.so

  • Review (and replace as appropriate) all cases of :

    AllowOverride None with AllowOverride All

    in the following files:
    httpd.conf, /extra/httpd-vhosts.conf, /extra/httpd-autoindex.conf and any related files you may be using.

  • Add the .htaccess file into the appropriate websites/folders
  • Restart the server to accept the changes

NOTE: If you develop or host on Windows, you’ll likely have problems creating the file because there is no filename, just a file extension. You can create (or download) it from any non-Windows host and use it without additional changes. Apache does let you use a different filename, but you also need to be careful to update related security configuration that is used to prevent download of such files.

Happy hosting!

Enabling the Apache2 – Tomcat5 mod_jk Connector

Tuesday, April 22nd, 2008

Often you want to use Apache HTTP for static content, yet use Tomcat for JSP and other Java type work.  This is a very common infrastructure for enterprise applications, particularly when using ‘pools’ of servers for performance, redundancy and security.  

In order to accomplish this, all connections need to be handled by the Apache webserver, which will delegate appropriate requests to Tomcat for it to process.

Here’s a simple setup to get you started:

  • First you need to get the connector appropriate to your installation:

    http://tomcat.apache.org/connectors-doc/

  • Next make sure the connector file is in the /conf folder of your Apache installation.

    NOTE: I prefer to use this path and leave the version name to make maintenance and backups easier.

  • Add the following line to httpd.conf

    LoadModule jk_module conf/mod_jk-1.2.26-httpd-2.2.4.so

  • Now, add the following to http.conf

    <IfModule jk_module>
    Include “c:/TOMCATPATH/conf/auto/mod_jk.conf”
    JkWorkersFile conf/workers.properties
    JkLogFile “c:/LOGSPATH/tomcat55_mod_jk.log”
    </IfModule>

  • Add the c:/APACHEPATH/conf/workers.properties file with the following (minimal) contents:

    worker.list=ajp13
    worker.ajp13.port=8009
    worker.ajp13.host=localhost
    worker.ajp13.type=ajp13

  • Finally, restart both Apache and Tomcat
  • The following file should have been created in c:/TOMCATPATH/conf/auto/mod_jk.conf

    ########## Auto generated on …some datetime… ##########

    <IfModule !mod_jk.c>
      LoadModule jk_module “C:/APACHEPATH/conf/mod_jk-1.2.26-httpd-2.2.4.so”
    </IfModule>

    JkWorkersFile “C:/TOMCATPATH/conf/jk/workers.properties”
    JkLogFile “c:/LOGSPATH/mod_jk.log”

    JkLogLevel emerg

    <VirtualHost localhost>
        ServerName localhost

        JkMount /webdav ajp13
        JkMount /webdav/* ajp13

        JkMount /servlets-examples ajp13
        JkMount /servlets-examples/* ajp13

        JkMount /jsp-examples ajp13
        JkMount /jsp-examples/* ajp13

        JkMount /balancer ajp13
        JkMount /balancer/* ajp13

        JkMount /host-manager ajp13
        JkMount /host-manager/* ajp13

        JkMount /tomcat-docs ajp13
        JkMount /tomcat-docs/* ajp13

        JkMount /manager ajp13
        JkMount /manager/* ajp13
    </VirtualHost>

If all went well, you should be able to access  your Tomcat server webapps on the regular HTTP port used by your Apache installation.

Cheers!
