This guide will explain how to set up phpMyAdmin 4 on a CentOS 6 VPS and configure it to use SSL.
PhpMyAdmin is a web based MySQL administration tool made to make MySQL administration much easier. PhpMyAdmin needs to have a web server (for example Apache) and at least PHP 5.2 and MySQL 5 installed on the server.
To install Apache, MySQL and PHP, use the following command:
yum install httpd mysql-server php php-mysql php-gd php-mbstring
Start Apache and MySQL services:
service httpd start service mysqld start
Set the Apache and MySQL services to start automatically when the virtual server boots:
chkconfig httpd on chkconfig mysqld on
Set a MySQL root password using the following command:
Follow the instructions; enter your new MySQL root password, say ‘Yes’ to all the options and your MySQL installation should now be secure.
Install OpenSSL and mod_ssl packages using the following command:
yum install mod_ssl openssl
Download and extract the latest version of phpMyAdmin available at http://www.phpmyadmin.net/home_page/downloads.php
cd /root wget http://sourceforge.net/projects/phpmyadmin/files/phpMyAdmin/4.0.9/phpMyAdmin-4.0.9-all-languages.tar.gz tar -xzf /root/phpMyAdmin*.tar.gz -C /var/www/html/ mv /var/www/html/phpMyAdmin-4.0.9-all-languages /var/www/html/php-My-Admin cd /var/www/html/php-My-Admin cp config.sample.inc.php config.inc.php
Edit the ‘config.inc.php’ configuration file and add the following line below ‘/* Authentication type */’:
$cfg['ForceSSL'] = true;
Next step is to generate a self-signed certificate.
Generate private key:
openssl genrsa -des3 -out your-domain.com.key 4096
openssl req -new -key your-domain.com.key -out your-domain.com.csr
Generate Self Signed Key:
openssl x509 -req -days 700 -in your-domain.com.csr -signkey your-domain.com.key -out your-domain.com.crt
Copy the files to the ‘/etc/httpd/ssl/’ directory:
mkdir -p /etc/httpd/ssl/ cp your-domain.com.crt /etc/httpd/ssl/ cp your-domain.com.key /etc/httpd/ssl/
Create new virtual hosts in Apache, for example:
NameVirtualHost *:80 NameVirtualHost *:443 <VirtualHost *:80> DocumentRoot "/var/www/html/php-My-Admin/" ServerName your-domain.com <Directory /var/www/php-My-Admin/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ErrorLog logs/your-domain.com_error_log TransferLog logs/your-domain.com_access_log LogLevel warn </VirtualHost> <VirtualHost *:443> DocumentRoot "/var/www/html/php-My-Admin/" ServerName your-domain.com SSLEngine on SSLProtocol all -SSLv2 SSLCertificateFile /etc/httpd/ssl/your-domain.com.crt SSLCertificateKeyFile /etc/httpd/ssl/your-domain.com.key <Directory /var/www/php-My-Admin/> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny allow from all </Directory> ErrorLog logs/your-domain.com.ssl_error_log TransferLog logs/your-domain.com.ssl_access_log LogLevel warn </VirtualHost>
Restart Apache service for the changes to take effect:
service httpd restart
Open your popular web browser and access the phpMyAdmin interface at https://your-domain.com
You will receive a warning about the SSL certificate not being trusted. This is normal and is expected. The SSL certificate we created is self-signed which is why the web browser is complaining. You can safely ignore that, accept the certificate and proceed to log in to phpMyAdmin.
Of course, you don’t have to do any of this if you use one of our Linux VPS Hosting services, in which case you can simply ask our expert Linux admins to install phpMyAdmin for you. They are available 24×7 and will take care of your request immediately. For updates, you can also refer to our guide on How to Install phpMyAdmin on CentOS 8.
