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.

http:/hostname/phpmyadmin
http:/hostname:2030/pma

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

URL Monitoring With Nagios

By wahab

On November 18, 2015

In Linux server, Nagios

Capabilities

Nagios provides complete URL monitoring of HTTP and HTTPS servers and protocols as well as full URL transaction monitoring.

Benefits

Implementing effective URL monitoring with Nagios offers the following benefits:
* Increased server, services, and application availability
* Fast detection of network outages and protocol failures
* Monitor user experience when accessing URLs
* Web server performance monitoring
* Web transaction monitoring
* URL monitoring

URL monitoring

By using the ‘check_http’ nagios command, we can monitor a specific url rather than checking the Apache service is up or not. This method is helpful to identify if the website is hacked and url is injected with malicious codes or there is some Apache or php errors and page is throwing an error instead. The normal Apache service check will return successful results in the above case.
We can check for a specific keyword string on the webpage. If that string not present, an error will be returned.

Here is an real example

define service{
    use                            urlmonitoring-service
    host_name                      server.linuxwebhostingsupport.in
    service_description            url_check
    check_command                  check_http!-H linuxwebhostingsupport.in -t 30 -R "Cpanel and WHM" -f follow
}

The above will check for the keyword “Cpanel and WHM” on the page “linuxwebhostingsupport.in”. If the keyword is missing or the page is not responding nagios will retun and error.

URL monitoring +SSL

You can refer to below example if the web page has SSL/TLS enabled.

define service{
    use                            urlmonitoring-service
    host_name                      server.linuxwebhostingsupport.in
    service_description            url_check
    check_command                  check_http!-H linuxwebhostingsupport.in -t 30 -R "Cpanel and WHM" -f follow --ssl
}

Here we added the option “–ssl” to the check command

URL monitoring on ht password protected page

Normal method will not work as we need to validate ht password protection first to see the page. You can use the following example for such pages.

define service{
    use                            urlmonitoring-service
    host_name                      server.linuxwebhostingsupport.in
    service_description            url_check_protected
    check_command                  check_http!-H linuxwebhostingsupport.in -a user:password -t 30 -R "Cpanel and WHM" -f follow --ssl 
}

Replace the username and password appropriately.
