一、简介
一款开源的压力测试工具，可以根据配置对一个WEB站点进行多用户的并发访问，记录每个用户所有请求过
程的相应时间，并在一定数量的并发访问下重复进行。
Installing Siege Stress Tester on CentOS 6.3
Siege, similar to Apache Benchmark, is an amazing stress testing tool for your web-server. You can spin up a number of connections to simulate concurrency of transactions and gain invaluable insight into how your app or website might perform while under, well, stress!
How to Install Siege on CentOS 6.3
To get started, simply download Siege from the official website and unpack it using Tar:
cd /opt wget http://www.joedog.org/pub/siege/siege-2.72.tar.gz tar -zxvf siege-2.72.tar.gz
Next, navigate to the Siege folder and compile it:
cd /opt/siege-2.72 ./configure make && make install
You’re done, let’s confirm that Siege is working by checking its version:
siege -v
Siege Examples
Try running a few of the Siege Examples below (at your own discretion) to verify that your setup is working:
siege -c25 -t1M www.example.com siege -c25 -t50s example.com
Common Errors
[alert] unsupported protocol
If you receive this error message, it means that you’re trying to Siege a website using https (SSL) without SSL installed – or – Siege cannot determine the location of your OpenSSL installation.
To fix this error, simply compile OpenSSL statically with Siege to get SSL support:
cd /opt wget http://www.openssl.org/source/openssl-1.0.1e.tar.gz tar -zxvf openssl-1.0.1e.tar.gz cd siege-2.72.tar.gz ./configure -with-ssl=/opt/openssl-233
