CodeIgniter is a PHP framework used to build web applications that are widely used by developers worldwide. Before you install CodeIgniter, make sure the following are installed beforehand:
- Webserver Apache or Nginx
- PHP 5.6
- MySQL
- Composer
Once you confirm that the above-listed components are on your server, proceed to install CodeIgniter with the following steps.
Step 1: Set SELinux status to disabled.
# SELINUX=disabled
Step 2: Let us create a MySQL Database for CodeIgniter.
# create database mycode_db;
# GRANT ALL PRIVILEGES ON mycode_db.* TO 'mycodeusr'@'localhost' IDENTIFIED BY 'your_password';
# flush privileges;
# exit
Step 3: Now, we will install Composer Package Manager.
# curl -sS https://getcomposer.org/installer | php
# mv composer.phar /usr/local/bin/composer
# chmod +x /usr/local/bin/composer
# exit
Step 4: We will install CodeIgniter. Go to the root directory of HTML.
# cd /var/www/html/
Step 5: Clone CodeIgniter from its git repository.
# git clone https://github.com/bcit-ci/CodeIgniter.git
Step 6: We will install the required dependencies by running composer.
# composer install
Step 7: Provide file ownership of files to the Apache user.
# chown -R apache:apache /var/www/html/
Step 8: We will configure the base URL by editing the config.php file.
# vi /var/www/html/application/config/config.php
Step 9: Locate the line below.
config['base_url'] = '';
Step 10: Modify this line by adding your application URL in the quotes.
config['base_url'] = 'http://192.168.2.152';
Step 11: To configure the CodeIgniter Database connection setting, edit the following file with your preferred text editor:
# vi /var/www/html/application/config/database.php
Step 12: Locate the path given below:
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => '',
'password' => '',
'database' => '',
'dbdriver' => 'mysqli',
Change it to:
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'mycode_db',
'password' => 'your-db-user-password',
'database' => 'mycodeusr',
'dbdriver' => 'mysqli',
Step 13: Once you are done with the changes, save this file. Access the URL (http://192.168.2.152) you added earlier in base_url and verify that CodeIgniter is working.
