I need to block an IP-address which tries to download my entire website. Currently I've blocked it using iptables.
Is there any way to block an IP automatically if it's trying to request to many pages, i.e. downloading an entire website?
P.S. I'm using Nginx as frontend to Apache.
Thank you!
I recently bought Xen VPS (linode.com) with Debian 5.0 Lenny (i386), 512MB RAM. At the moment I have only three small websites (built with Drupal) with about 600 users per day in total running on this server.
As a web server I use nginx 0.7.67 (PHP 5.3.3 with php-fpm). An average memory consumption is about 100-105MB. Here is what Munin graph shows:
and this is what "top" command diplays (sorted by memory usage):
In my php5-fpm.conf:
pm = dynamic
pm.max_children = 50
pm.start_servers = 2
pm.min_spare_servers = 2
pm.max_spare_servers = 5
pm.max_requests = 500
Before migrating some bigger projects to this VPS I'd like to know if this is a normal memory consumtion for this kind of server configuration? How many users on the website (let's say, built with Zend Framework) this VPS can handle?
Thank you!
I'm working on a project where we need to store static files (user images, videos, etc.) on a different server (nginx serves static files). I haven't worked with a separate static file server before, so I don't even know how to save/edit/delete user files on a remote server.
Any links, suggestions, hints would be greatly appreciated.
thank you!
UPD. Debian Lenny 5.0, standard http, Apache, Nginx, PHP 5.2
I've recently installed munin on my VMware client server and saw that the Disk usage shows about 80-90%. Everything else (cpu load, ram, etc.) seems to be running fine. I have only two virtual hosts on my server with 1000 users/day in total, so I don't think that's too much.
Here is the graph for the disk usage.
Server info: Debian Lenny, CPU 510Mhz, RAM 512MB
Is it bad? What could possibly cause this?
Thank you for any suggestions.
How do I create a new user in Debian without home directory?
How do I create a user with root privileges in Debian? Maybe it sounds a bit silly, but I don't think I need user directories, only some rights to run services (mainly web server, mysql, etc.). I just don't want to run everything under root account.
Thank you.
I'm trying to setup Apache2.2 with mod_fcgid and libapache2-mod-perl2 with no luck.
I've created a fcgi-bin directory in the root directory of my website and put there a test.fcgi file with the following content:
#!/usr/bin/perl
use CGI;
print "This is test.fcgi!\n";
While trying to access it via http://www.website.dom/fcgi-bin/test.fcgi I get error 500 (Internal Server Error).
Here is my vhost config:
<VirtualHost 95.131.29.226:8080>

I've no clue why I'm getting error 500, but when I'm trying to access this file using console ($ perl /var/www/data/website.com/fcgin-bin/test.fcgi) everthing works fine without any errors...
Any suggestions on how to solve this problem would be greatly appreciated.
Thank you!
I have a website hosted on a VPS (512Mb - minimum guranteed memory, 510Mhz proccessor, Debian 5.0 Lenny, Apache 2.2.9 with nginx 0.7.65 as a frontend to serve static content, MySQL 5.1.44, PHP 5.3.2 with APC caching).
I'm a web developer, so I'm not very good at optimizing servers, but I've managed to install and setup all those neccessary components (LAMP, nginx, etc.). After that I decided to stress test my website (which uses Drupal 6.16 with caching and all possible optimization enabled) using a utility called "Webserver Stress Tool 7". And it seems to me that the results aren't any good - here is a graph (sorry, as a new user I'm not allowed to post images)
As you can see the response time depending on amount of simultaneous users increases very quickly. With 10 simultaneous users the time is about 1000ms, with 100 simultaneous users it's about 15000ms (15s!).
The question is do you think this is normal behavior for such a server or something is wrong with the settings and optimization? If you think something is wrong what particulary could be wrong? Any other suggestion how to speed this a little bit up?
