.htaccess file not works in LAMP - php

Question

This is my .htaccess file. I am used Codeigniter Framework for my project.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /project_name/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
Where is my mistake here? But It Works in xampp.

Answer 1

You can't just move from one server to another and not make sure your prerequistes are there. These things are not on by default on most systems. You also have not given any specifics about your setup or even your document root.
So going off that it's an Ubuntu server and apache2, you need to do these things.
First thing you need to do if this is a new LAMP install is make sure rewrite is on.
Run this command to enable mod_rewrite.
sudo a2enmod rewrite
Then you need to make sure you allow .htaccess in your document root.
edit
/etc/apache2/sites-available/000-default.conf
In this file search for this
AllowOverride None
and change it to
AllowOverride All
Then restart apache2.
sudo service apache2 restart
EDIT: Based on your comment, you need to make your vhost look like this and then restart apache2.
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www/html
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory /var/www/html>
AllowOverride All
</Directory>
</VirtualHost>

Answer 2

Open your terminal
Run this following code:
sudo nano /etc/apache2/apache2.conf
go down and change:
AllowOverride All
look like:
<Directory /var/www/>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
Then restart apache2.
sudo service apache2 restart
and then .htaccess file is
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

Are you sure mod_rewrite module is loaded ? go to httpd.conf and search for -
LoadModule rewrite_module modules/mod_rewrite.so
and make sure theres no # [hash tag] before
