phpMyAdmin is installed with CentOS Web Panel. By default, it is not protected and there is only MySQL user authentication. This can put your server vulnerable. So it is recommended to add additional layer protection.

phpMyAdmin is available through the following url in a CWP based server.


CWP panel runs its core services through its own version of Nginx. So normal htaccess based password protection will not work.

Create the Password File

You can do this by using the OpenSSL utilities that may already be available on your server. Alternatively, you can use the purpose-made htpasswd utility included in the apache2-utils package(Debian/ubuntu) or httpd-tools(Redhat/Centos).

Using OpenSSL Utilities

We will create a hidden file called .pma_pass /usr/local/cwpsrv/var/services/ folder. You can use any username. I am using dbadmin here as an example

sudo sh -c "echo -n 'dbadmin:' >> /usr/local/cwpsrv/var/services/.pma_pass"

Next, add an encrypted password entry for the username by typing:

sudo sh -c "openssl passwd -apr1 >> /usr/local/cwpsrv/var/services/.pma_pass"

Using Apache Utilities

This tool is already installed and available on all CWP servers.

/usr/local/apache/bin/htpasswd -c /usr/local/cwpsrv/var/services/.pma_pass dbadmin

Configure Nginx Password Authentication

We will need to configure Nginx to read this file before serving our protected content.
CWP Service Nginx configuration file: /usr/local/cwpsrv/conf/cwp_services.conf

Open the above file add the following to the location block of phpMyAdmin.

auth_basic “Admin Login”;
auth_basic_user_file /usr/local/cwpsrv/var/services/pma_pass;

So the full block should look like this now.

location /pma {
    root /usr/local/cwpsrv/var/services;
    index  index.html index.htm index.php;
    ModSecurityEnabled off;
    ModSecurityConfig /usr/local/cwpsrv/conf/security/conf/pma_rules.conf;

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_read_timeout 600;
        fastcgi_pass    unix:/usr/local/cwp/php71/var/sockets/cwpsvc.sock;
        fastcgi_index   index.php;
        fastcgi_param   SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        fastcgi_param   SCRIPT_NAME   $fastcgi_script_name;
        include                 fastcgi_params;

    location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
        access_log    off;
        log_not_found    off;
        expires 1M;

       auth_basic "Admin Login";
       auth_basic_user_file /usr/local/cwpsrv/var/services/.pma_pass;

Restart CWP nginx service by below commands

systemctl restart cwpsrv.service

Confirm the Password Authentication

To confirm that your content is protected, try to access your restricted content in a web browser. You should be presented with a username and password prompt
