This is my second article talking about Linux cloud computing server. As a full stack developer, it seems to be out of my scoop. However, as a beginner in Linux Cloud computing industry, I think it will be a good idea to share my problems and solutions when I am working on Linux cloud computing server.
Usually, here is the normal working process on Linux cloud computing server:

1. Estimate hardware requirement including CPU, memory, storage, I/O, or GPU (more and more tasks use GPU now), and networking.
2. Purchase cloud computing server from vendor such as Amazon, Microsoft, Google, etc.
3. Use SSH to login Linux server and setup software and services.

However, things don’t always happen the way you plan them to happen. This time, I need a Linux cloud server to setup Web server with database. One of my friend have a free one and share that one with me. He passes me the username, password and IP address to access the server. I know nothing about the server but the system is Linux. So I login the server and try to find out following information about the server:

1. CPU information
2. Memory information
3. Storage
4. System information
5. Software and Service
6. Users and Groups

Today, everybody is using Git to manage project version control job. Here I don’t want to mention how hot the Git is. But I want to say that if you don’t know how to use Git, you will be out of the IT industry. As an old IT developer, I has been working on SVN for several years. To be honest, it is tough to move from SVN to Git, though Git is a little bit similar with SVN. However, we must follow the trend. The best way to learn how to use Git is starting a new project and using Git to manage the version control in command line. In this post, I will record how I start my first project with Git. I think it will be very helpful for another people who is new to Git. As a beginner, I may make some mistakes here. So please leave a reply if you find any mistakes.

This is my first time to realize how important to keep a website secure.
