Apache mod_evasive Mod_evasive is a module available for the Apache HTTP server that can automatically block attacks by rate-limiting any IP that sends too many requests in a short time. Start by installing the module from WHM’s  EasyApache 4  interface. Select the  Currently Installed Packages  profile, search for  mod_evasive  in the  Apache Modules  section, and then install it. The default settings are good for most servers, but you can tweak them further by editing the configuration file  /etc/apache2/conf.d/300-mod_evasive.conf . You can also whitelist specific IP addresses or classes, so legitimate requests are not blocked. Configure CSF to block attacks While  mod_evasive  works very well, it only protects the Apache webserver. In order to harden other services as well, you can install the free  ConfigServer Security & Firewall  (CSF), which also includes a WHM plugin. As the  root  user, install CSF with these terminal commands: cd /usr/src rm -fv csf.tgz wget https://down

J'ai eu une surcharge sur un site web avec l'ouverture des réservations , les visites  ont explosées. Solution : j'ai effectué une redirection vers un serveur héberger a l’étrange où Twitter où Facebook, et j'augmente le   MaxRequestWorkers à 250 You can update the MaxRequestWorkers value in WHM with the following steps: Log in to WHM as the root user. Navigate to  Home »Service Configuration »Apache Configuration »Global Configuration . Update the "Max Request Worker" value. Set the ServerLimit value to something larger than MaxRequestWorkers Select Save.

  how can i limit access APACHE only in "domaine.dz" ? Not necessarily through Apache, however, php-fpm would do this if this domain was set to use the PHP-FPM handler. Activating fpm for this domain would allow them to limit the amount of traffic this user can have concurrently through the max_children variable. Information on this variable will be below. PHP-FPM Performance Tuning Basics I see that the PHP-FPM php handler isn't enabled or installed on this server. So what I'd suggest if you'd like to do this is to install the PHP-FPM handler and set this domain to use this: How to install PHP-FPM How to change PHP handlers   How can i add performance of my APACHE, without disrupting mail which is important then to the APACHE ? I see that the server's Apache installation reached the maxrequestworkers variable which prevented traffic for the server from being processed. The MaxRequestWorkers variable limits the amount of concurrent processes apache is handling
