Jmeter is basically used for load testing of web applications.

JMeter is to first download the latest production release and install it. The release contains all of the files you need to build and run most types of tests, e.g. Web (HTTP/HTTPS), FTP, JDBC, LDAP, Java, and JUnit.

If you want to perform JDBC testing, then you will, of course, need the appropriate JDBC driver from your vendor. JMeter does not come with any JDBC drivers.

If you want to install the jmeter on your linux box you need to follow my steps

1) Goto http://jakarta.apache.org/site/downloads/downloads_jmeter.cgi
2) Download Binary 2.3.4.zip . The zip file name will be “jakarta-jmeter-2.3.4″
3) Paste it in /var/www/html/
4) Unzip “jakarta-jmeter-2.3.4″
5) New folder with name “jakarta-jmeter-2.3.4″ will be created
6) Go to command prompt
7) go to “jakarta-jmeter-2.3.4″ folder (cd /var/www/html/jakarta-jmeter-2.3.4)
go to “bin” folder (cd bin)
9) Now you are in bin folder (i.e /var/www/html/jakarta-jmeter-2.3.4/bin/)
10) type the command “sh jmeter”
11) After a short pause, the JMeter GUI should appear.

After this you can use following commands for load testing.

For non-interactive testing, you may choose to run JMeter without the GUI. To do so, use the following command options

-n This specifies JMeter is to run in non-gui mode

-t [name of JMX file that contains the Test Plan].

-l [name of JTL file to log sample results to].

-r Run the test in the servers specified by the JMeter property “remote_hosts”

-R [list of remote servers] Run the test in the specified remote servers

The script also lets you specify the optional firewall/proxy server information:

-H [proxy server hostname or ip address]
-P [proxy server port]

Example : jmeter -n -t my_test.jmx -l log.jtl -H my.proxy.server -P 8000

ABOUT SIEGE
Siege is an http load testing and benchmarking utility. It was designed to let web developers measure their code under duress, to see how it will stand up to load on the internet. Siege supports basic authentication, cookies, HTTP and HTTPS protocols. It lets its user hit a web server with a configurable number of simulated web browsers. Those browsers place the server “under siege.”

PLATFORM SUPPORT
Siege was written on GNU/Linux and has been successfully ported to AIX, BSD, HP-UX and Solaris. It should compile on most System V UNIX variants and on most newer BSD systems. Because Siege relies on POSIX.1b features not supported by Microsoft, it will not run on Windows. Of course you can use Siege to test a Windows HTTP server.

If you try to install memcached with Linux server then use following commands

# yum install libevent
# yum install libmemcached libmemcached-devel
# yum install memcached

For Starting the memcached server
# memcached -d -m 512 -l 127.0.0.1 -p 11211 -u nobody

11211 port is default port for memcached server.

For using the memecached with php client you need to install following package

# pecl install memcache

After installing all packages restart the apache server.

# /etc/sbin/service httpd restart

<?php
/* OO API */
$memcache_obj = new Memcache;
$memcache_obj->connect('memcache_host', 11211);
$memcache_obj->set('any_key', 'some value', MEMCACHE_COMPRESSED, 50);
echo $memcache_obj->get('any_key');
?>

Important Note: Memcached key has limitations of 250 charactors, So key value should be with in 250 charactors.

For this example I used the RHEL 5.3 edition. If server is new then use follwoing commands to keep server up to date.
When I tried to install php-pear lib in server I am not able to install all the pear libs. Then I Used following commands for installing the php-pear fully.

# yum update
# up2date -u
# yum install lighttpd-fastcgi php-cli php-mysql php-gd php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-eaccelerator php-magickwand php-magpierss php-mapserver php-mbstring php-mcrypt php-mhash php-mssql php-shout php-snmp php-soap php-tidy php-pear php-devel httpd-devel mysql-server mysql-devel

The 2 RPMs which we need are:
epel-release and remi-release

# wget http://download.fedora.redhat.com/pub/epel/5/i386/epel-release-5-3.noarch.rpm
# rpm -Uvh epel-release-5-3.noarch.rpm

# wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
# rpm -Uvh remi-release-5.rpm

# yum install php-pear*

# /sbin/service httpd start
# /sbin/service mysqld start

# php -v

Nginx web server is becoming most popular in last year. Best server response time and minimum execution time is the advantages of Nginx server.

Many people want to remove the www from URL. I will tell you the tip how to remove the www from URL with nginx server.

Open your Ngnix configuration file (nginx.conf). Just use following code in server block.

if ($host ~* ^www\.(.*)) {
    set $remove_www $1;
    rewrite ^(.*)$ http://$remove_www$1 permanent;
}

This code will remove the www from the URL.

Now these days keeping www in URL is becoming old fashion. How can check many websites for that and the current example is twitter.com

I specially dont like to put www in URL so we can easily remove the www from URL.

Open your apache configuration file. If you are using Linux then open file from following location

# vim /etc/httpd/conf/httpd.conf

put following lines in your virtual directory section.

# remove www from url
RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
RewriteRule ^.*$ http://example.com%{REQUEST_URI} [R=301,L]

We can use this rewrite rule in .htaccess file also. But make sure .htaccess is enable through apache server.

# remove the www from URL.
Options +FollowSymlinks
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
RewriteRule ^.*$ http://example.com%{REQUEST_URI} [R=301s,L]

For WordPress websites for seo purpose putting above lines in .htaccess file is really best. That will gives you the really great result in future.

Many times we need to run the linux commands using PHP language. This is my favorite question about PHP when I take interview of new PHP developer.

In this article I will show you how to execute the linux command using PHP language syntax or script.

You can execute linux commands within a php script – all you have to do is put the command line in backticks (”) ,exec() , and shell_exec().

$command = exec('linux command');
echo $command;
echo shell_exec('ll');

Many times this issue is happened with me I tried the kill command to stop the process.
But that is really not responding. For Example, following command executed but not worked

[siwan@siwank-pc ~]$ ps -ef|grep skype
siwan     3140     1  1 09:50 ?        00:04:46 skype
siwan    13857 13818  0 17:24 pts/1    00:00:00 grep skype
[siwan@siwank-pc ~]$ kill 3140

There are really very nice unix commands present in Linux like:

[siwan@siwank-pc ~]$ killall firefox

[siwan@siwank-pc ~]$ ps -ef|grep skype
siwan     3140     1  1 09:50 ?        00:04:46 skype
siwan    13857 13818  0 17:24 pts/1    00:00:00 grep skype

[siwan@siwank-pc ~]$ kill -9 3140

I specially like the kill -9 processid command. Using kill -9 on a process is like just hitting the power button on your running PC. You already know that powering off a running PC can damage your filesystem because of run-time inconsistent data, why would you do the same thing to your applications? You risk the _exact same_ data corruption.

How to setup Firefox Profile Manager on Fedora or Linux

Firefox has new functionality called Profile manager which will allow you to switch with multiple Users.
You can create many user profiles in Firefox and save that as per your choice.

Many times on same Firefox some user don’t want some addons or theme. That time we got some difficulties.
For avoiding this issue we can create the firefox profile in firefox.

In windows creating Firefox profile is very easy. Just open windows run window and type “firefox -P”. That sit!

You will see following screens.

Using this you can create the firefox profiles.

Now I am going to show you how to create the firefox profile in Fedora.

Open terminal and just type following command

[siwan@siwank-pc ~]$ /usr/lib/firefox-3.5.6/firefox -ProfileManager
[siwan@siwank-pc ~]$

See following screens.
Note: when you got “choose user profile” window. Don’t forget to uncheck the “Don’t ask startup” checkbox.

Note:  I am using the Fedora 11 here for this example.

In now day many times we heard about cloud hosting and cloud computing. Recently we heard from Matt (WordPress founder) also. Many web designers are not aware with cloud hosting.

In this article I am going to write about in detail about cloud hosting. We are heard about messaging servers and big web services.

Twitter is the biggest mirco blogging website in the world and they are running like more then 100 mongrel server instances on Nginx server for handling the twitter. But still they are facing lot of traffic issue. May be there are multiple reasons. But still one of that is Rails. How much requests single mongrel instance can handle and if they got billions of hits in single second. What will happen we never no.

Who are in server administration they will defiantly have good idea about these issues.

What is cloud hosting?

Cloud hosting is nothing but multiple virtual machines which are basically does load balancing.

Generally, website hosted on a cloud hosting operates on a clustered servers where online operations are not limited to a single server. By handling security, load balance and hardware resources virtually, the website has access to the processing power of a number of servers that are distributed in real time.

Cloud computing is a way of computing, via the Internet, that broadly shares computer resources instead of having a local personal computer handle specific applications.

I can say Cloud hosting is solution for multiple dedicated servers. Handling multiple dedicated server is really pain. So for high traffic websites choosing the cloud hosting is the best option.

Google, Yahoo, MSN, Facebook many companies are already using the cloud hosting for better performance.

For choosing the cloud hosting there are few good options present in market. Some of few as follows:

1. Amazon
