Removing index.php from url of CodeIgnitor project | Using .htaccess file

Step 1 : Edit the configuration file to give the permission to override default settings.
command: sudo nano /etc/apache2/sites-available/default
Change the value of AllowOverride to ‘All’ from ‘none’


    ServerAdmin webmaster@localhost

    DocumentRoot /var/www
        Options FollowSymLinks
        AllowOverride All                                 <- HERE
        Options Indexes FollowSymLinks MultiViews
        AllowOverride All                                 <- HERE
        Order allow,deny
        allow from all

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
        AllowOverride None
        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all

    ErrorLog ${APACHE_LOG_DIR}/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined

    Alias /doc/ "/usr/share/doc/"
        Options Indexes MultiViews FollowSymLinks
        AllowOverride None
        Order deny,allow
        Deny from all
        Allow from ::1/128

Step 2: Enable module rewrite
command: sudo a2enmod rewrite

Step 3: Restart apache server
command: sudo service apache2 restart

sample .htaccess:

RewriteEngine on
RewriteCond $1 !^(index.php|images|robots.txt)
RewriteRule ^(.*)$ /index.php/$1 [L]

N.B: Don’t forget to press Enter once at the end of the htaccess file.Because Newline represents the end of file.
