#การใช้ Git ฉบับรีบร้อน

##Git Git เป็น revision control แบบ distributed (หมายความว่าไม่มีศูนย์กลาง) และ แบบ non-linear history (หมายความว่ามีประวัติการเปลี่ยนแปลงแบบไม่ใช่เส้นตรง) ดังนั้นทำให้คอนเซปต์ของ Git นั้นต่างจาก revision control รุ่นก่อนหน้าหลายอย่าง

ต่อไปจะอธิบายย่อๆเรื่องคำสั่ง Git โดยอิงกับการทำงานใน GitHub เป็นสำคัญ (Git มีวิธีใช้พลิกแพลงมากมาย ไปศีกษาการใช้อื่นได้ด้วยการไป Google เอาเอง)

สมมุติว่ามี repository แห่งนีงใน GitHub เช่น https://github.com/norsez/projectA

Clustering: The basics

The trick? pass the file descriptor from a parent process and have the server.listen reuse that descriptor. So multiprocess in their own memory space (but with ENV shared usually)

It does not balance, it leaves it to the kernel.

In the last nodejs > 0.8 there is a cluster module (functional although marked experimental)

• http://nodejs.org/api/cluster.html
• Simple cluster example:

jgoodall

This is a sample of how to send some information to logstash via the TCP input in nodejs or python. It assumes the logstash host is on 10.10.10.100 and the TCP listening input is 9563.

The logstash.conf should look something like the sample file.

The log message should be a stringified JSON object with the log message in the @message field.

To use, run the node script node sendMessageToLogstash.js, or the python script python sendMessageToLogstash.js

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
