Codeiginter : Error in URL - php

Question

My front url is-
http://localhost/myProject/
admin url is -
http://localhost/myProject/admin
It works in windows but not works on Ubuntu.
It gives error "Not found".
What works in ubuntu -
The front page is working - http://localhost/myProject/
The admin login page is working if I add index.php in url like this -
http://localhost/myProject/index.php/admin
Not other pages are working
My .htaccess file contents-
RewriteEngine on
RewriteCond $1 !^(index\.php|assets|themes)
RewriteRule ^(.*)$ /myProject/index.php/$1 [L]
My Apache's mod-rewrite module is on.

I was also following the similar issue in Centos, and I followed the below tutorial :
How to permit changes in the .htaccess file:
open httpd using ------------------> vi /etc/httpd/conf/httpd.conf
Once inside that file, find the following section, and change the line that says AllowOverride from None to All. The section should now look like this:
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride All
Order allow,deny
allow from all
</Directory>
After you save and exit that file, restart apache. .htacess files will now be available for all of your sites.
service httpd restart
Content of .htaccess file:
<IfModule mod_rewrite.c>
Options +FollowSymLinks -Indexes
RewriteEngine on
# NOTICE: If you get a 404 play with combinations of the following commented out lines
#AllowOverride All
#RewriteBase /
# Restrict your site to only one domain
#RewriteCond %{HTTP_HOST} !^www\.
#RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|images|fonts|js|images|robots\.txt|css)
<IfModule mod_php5.c>
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
<IfModule !mod_php5.c>
RewriteRule ^(.*)$ index.php?/$1 [L]
</IfModule>
</IfModule>
#prevent access to htaccess file
<Files .htaccess>
order allow,deny
deny from all
</Files>
#disable directory browsing
Options All -Indexes
IndexIgnore *
