Performance testing tool curl-loader (Linux)

 

Curl-loader Introduction

Curl-loader ( Also known as" Omes - Nik " And " Davilka " ) Yes An Open Source Of C Language Write Of Tools , Simulation Application Load And Tens of thousands Dozens Tens of thousands HTTP/   HTTPS and FTP /   Ftps Client ApplicationProgram Of Action , Each Yes Its Own Source IP address . On the contrary, OthersCurl-loader Use True C Write Of Customer End Protocol Stack , That is Libcurl and TLS /   OpenSSL SSL HTTP and FTP Protocol Stack , Supported Login And Verify Taste And Simulation User behavior Of Tools .

Therefore, although the size is small, do not underestimate his capabilities! Pai_^ curl-the loader performance testing tool was heard when it was initially tested. However, since it runs in a Linux system, it has never been downloaded and used, now we can take the opportunity to learn about Linux.

Build it using general C development environment with Bash,
GCC (3 or 4 series), make, etc on a Linux machine.

Building pre-requirements are:
1. OpenSSL binaries;
2. OpenSSL development package with include files (On Debian package libssl-Dev)

  If your Linux system has a GCC and OpenSSL environment, you can skip the following content. If not, install it with me. -------------------- Install GCC ---------------------------------------------------------------------------- First, We must have GccEnvironment: Method 1 For RedHat/centos Linux, run the following command to download and install [Root @ youname test] #Yum install GCC gcc-C ++Download and install the C Compiler

 
Method 2
 

Rpm InstallationIf the system disk has been installed, you can insert the installation disc and run the following command (for details about how to insert the installation file for a VM ):
 

 
[Root @ youname test] # Rpm-ivh gcc *
 

---------------------------- Install OpenSSL Bytes ------------------------------------------------------------------------------------ Second, Requires us to install OpenSSLPackage [Root @ youname curl-loader-0.56] # Rpm-Qa | grep SSLCheck whether you have installed the OpenSSL service. Method 1 Download and install the corresponding service (the method is cumbersome. Here is the link) Download: Http://download.chinaunix.net/download/0001000/11.shtml Installation Method: Http://myswirl.blog.163.com/blog/static/513186422007101410149578/ Method 2 The above method is troublesome. The simplest method is to insert the system disk in the DVD/CD mode, and find it in the System Disk/centos/RPMS/directory: Openssl-0.9.7a-43.17.el4_7.2.rpm Openssl-devel-0.9.7a-43.17.el4_7.2.rpm For the two RPM packages, click "Install and restart.   Of course, you can also refer to Method 2 Install using commands

 
[Root @ youname test] #Rpm-IVH [file name]
 

Certificate ------------------------------------------------------------------------------------------------------------------------------------------------- After the prerequisite environment is met, the following command starts installation.

[Root @ youname test] #MakeAutomatic compilation   After compilation, the curl-loader executable program provides some examples for us. Let's take a look at how to configure the performance options in the example. [Root @ youname curl-loader-0.56] # CD conf-examples/Example directory [Root @ youname conf-Examples] # CP 10k. conf mysimp. confCopy the 10k. conf file to the current directory and name it mysimp. conf. [Root @ youname conf-Examples] #VI mysimp. confOpen Edit Mysimp. confFile

After the preceding content is configured, save and exit.   Perform Performance Testing   Run the following command to start running our performance test. [Root @ youname curl-loader-0.56] # Curl-loader-F./conf-examples/mysimp. conf

During the test, the above information is constantly updated (refreshed. The environment is finally running. The detailed usage of curl-loader will be learned later.
