MogileFS Distributed File System Construction
MogileFS is an open-source distributed storage software suitable for storing massive small files. It consists of three parts: tracker, mogstore, and database.Tracker: It stores metadata information through databases, including site domain, class, host, etc. Its main functions include monitoring back-end Storage nodes, and instructing Storage nodes to add, delete, and query data, and data replication betwee

This tracker maintains a unique number for each view of the application, and a Hibernate ing about which Hibernate entities affect each view. Every time a POJO is changed, the counter that uses the view of the object is added with 1. We use this count value as the ETag, so that when the client sen

When configuring Fastdfs, modifying the configuration file is a very important step and understanding the meaning of each item in the configuration file is more important, so I refer to the great God's post and organize the explanation of the configuration file.

introduction of Fastdfs
Fastdfs is an open source lightweight Distributed File system developed by HAPPY_FISH100, and she manages the files, including file storage, file synchronization, file access (file upload, file downloading), etc., which solves the problem of large capacity storage and load balancing. Especially suitable for the document as the carrier of online services, such as photo albums, video sites and so on. The FASTDFS server has two roles: Tr
Recently, to improve storage performance (mainly write performance) for small files (around 100KB), the idea of using FASTDFS requires a simple test of its performance.
1. Install Fastdfs
Cd/opt mkdir fastdfs cd fastdfs
git clone https://github.com/happyfish100/fastdfs.git
git clone https://github.com/happyfish100/libfastcommon.git

For as unfamiliar, I would like to explain this: enemy._x + = (dx>=0), Enemyspeed:-enemyspeed), in fact, is equivalent to the following sentence:
if (dx >= 0) {enemy._x = enemy._x + enemyspeed;} else {enemy._x = Enemy._x-enemyspeed;}
This is used to determine the direction of the enemy's movement, according to DX dy positive and negative conditions, to determine which direction to move.
