#chmod -R 777 FOLDER_NAME

Solved issue -Directory index forbidden by Options directive:

I want to change the default location of Apache folder which is (var/www/html).
I am using the Fedora as OS and apache 2 here. you can use following code with any linux box like centos or ubuntu. Here we solved the issue of directory.

When I inserted the following code in bottom of the httpd.conf file.
<VirtualHost *:80>
Options +FollowSymLinks
ServerAdmin siwan@yahoo.co.in
DocumentRoot /var/www/html/testfolder
ErrorLog logs/error_log_net
TransferLog logs/access_log_net
</VirtualHost>

When tried the http://localhost/ in browser, I got the default browser page.
Then I tried to look my apache error using following command:
#[root@localhost ]# tail -f /var/log/httpd/error_log

In apache error log I got following error.
[Wed Oct 07 15:59:50 2008] [error] [client 127.0.0.1] Directory index forbidden by Options directive: /var/www/html/testfolder/

I changed the AllowOverride option but nothing is happens. Then I read the welcome page text
“To prevent this page from ever being used, follow the instructions in the file /etc/httpd/conf.d/welcome.conf.”
I opend the welcome.conf file.

I found following lines in welcome.conf file.
<LocationMatch “^/+$”>
Options -Indexes
ErrorDocument 403 /error/noindex.html
LocationMatch>

I changed that to as follows:

[viral-lock message=”Solution code is Hidden! It’s Visible for Users who Liked/Shared This article on Facebook or Twitter or Google+. Like or Tweet this article to reveal the content.”]

<LocationMatch “^/+$”>
Options Indexes
ErrorDocument 403 /error/noindex.html
</LocationMatch>

[/viral-lock]

That solve my problem. Some time your selinux will cause the issue so you need to deactivate the selinux.
Some time File permission will also cause the issue.
You can change the file permission using following command, go to that directory and run following command.
#chmod 777 *

You can use above commands on any linux box. Ubuntu, centos, redhat or on fedora box.. still solution will be same.
