We are providing This page provides a step-by-step guidance to setup the Kafka site as your local apache serverguide to set up the contents of the Kafka website (https://kafka.apache.org/) as your local Apache HTTP Server's homepage. This could be is useful when you are contributing doc changes, and would like to have a easy way of displaying and debugging your modified website. The guidance itself is based on OSXdocumentation changes, for which you need verify that any modified pages of yours still display and render correctly. This guide is based on macOS, but should be easily adopted for other operating systems like Linux/Unix OS as well. 

1. Make

...

sure the Apache HTTP Service is

...

installed

On macOS, the Apache HTTP

In OSX, Apache Http Service should be installed by default. To validate it, you can check if command "apachectl" exists   exists or not:

$ sudo apachectl start

(If Apache Web HTTP Service is not installed, follow this page to download and install it.

And then on your browser, see if

localhost

renders successfully or not. For example, by default it will load the page defined in

...

)

Now, verify your local HTTPD installation by accessing its default web page: In your browser, visit http://localhost to verify that the homepage renders successfully. By default, you should see the text "It Works!" from /Library/WebServer/Documents/index.html.en

...

And you should see "It Worked!" text. 

2. Make

...

sure you have a local fork of the kafka-site git repository

Make sure you have cloned your forked kafka-site git repo (e.g. https://github.com/guozhang/kafka-site) from the apache official Apache git repo (https://github.com/apache/kafka-site) in your local directory, and then . Then add the apache git repot as an additional remote repo.

For example, after these steps your local repo should look likesimilar to:

guozhang$ @kafka-site: pwd

/Users/guozhang/Workspace/github/guozhangwanggit/kafka-site 


guozhang @kafka-site: $ git remote -v

apache	https://github.com/apache/kafka-site.git (fetch)

apache	https://github.com/apache/kafka-site.git (push)

origin	https://github.com/guozhangwang/kafka-site.git (fetch)

origin	https://github.com/guozhangwang/kafka-site.git (push)


guozhang @kafka-site: $ git checkout asf-site
 
guozhang$ @kafka-site: git branch

* asf-site

3. Modify the Apache

...

configuration to point to your local fork

Now you need to find edit the Apache Http Service HTTPD config file and start editing on it. The config file could be found as (depending on your OS type and version).

# The location of the configuration file may vary depending on the OS.
$ 

sudo vim /etc/apache2/httpd.conf

And make Make the following changes on this file:

to the configuration.

Step 1: Uncomment Step 1. Uncomment the following two lines . This is to enable loading so the "mod_include" and "mod_rewrite" modules are loaded on server startup.

LoadModule include_module libexec/apache2/mod_include.so
...
LoadModule rewrite_module libexec/apache2/mod_rewrite.so

...

Step 2.: Change "DocumentRoot" and "Directory" to your  and Directory to point to the local clone of your forked kafka-site repo directory ; and (e.g., "/Users/guozhang/git/kafka-site"). Also, change AllowOverride from "None" to "All". The three changed lines are marked below:.

# File: /etc/apache2/httpd.conf
#
# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory, but

# symbolic links and aliases may be used to point to other locations.

#

DocumentRoot "/Users/guozhang/Workspacegit/github/guozhangwang/kafka-site"             # <<< thisTHIS lineLINE isIS changedCHANGED

<Directory "/Users/guozhang/Workspace/github/guozhangwanggit/kafka-site">              # this<<< lineTHIS isLINE changed

    #IS CHANGED

    # Possible values for the Options directive are "None", "All",

    # or any combination of:

    #   Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews

    #

    # Note that "MultiViews" must be named *explicitly* --- "Options All"

    # doesn't give it to you.

    #

    # The Options directive is both complicated and important.  Please see

    # http://httpd.apache.org/docs/2.4/mod/core.html#options

    # for more information.

    #

    Options FollowSymLinks Multiviews

    MultiviewsMatch Any




    #

    # AllowOverride controls what directives may be placed in .htaccess files.

    # It can be "All", "None", or any combination of the keywords:

    #   AllowOverride FileInfo AuthConfig Limit

    #

    AllowOverride All                                                               # this<<< lineTHIS is changed




    #LINE IS CHANGED

    # Controls who can get stuff from this server.

    #

    Require all granted

</Directory>

4. Reload the Apache HTTP Service

...

Now simply restarting the Http web service:

sudo apachectl restart

And refreshing on your browser should then show up the complete Kafka site.

localhost

...

configuration

Restart the webserver to make the config changes take effect:

$ sudo apachectl restart

# If the command above does not work (and you still see the default "It works!" page), try the following variant.
$ sudo apachectl -k restart

In your browser, visit http://localhost/ again and refresh the page (Cmd+R on macOS). You should then see the complete Apache Kafka website, rendered from your local fork.

From now on, whenever you edited files in your local kafka-site fork, you can repeat the step above (i.e., restarting the webserver) to see your latest changes in your browser. Remember to refresh any browser tabs.

...

...

...

...

...

5. Shutdown the Apache HTTP Service

If you want to shutdown the web server, simply typerun the command:

$ sudo apachectl stop

# If the command above does not work (and the webserver is still running), try the following variant.
$ sudo apachectl -k stop
