It is believed that many inexperienced people don't know what to do about how to implement the file system of storage system in Redis. Therefore, this paper summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

What are the file system implementation methods of Redis storage system?

Method of use

After installing redisfs, run the following command, specify the host and port of the Redis server, and specify the mount directory. You can mount a file system with Redis as storage support in this directory.

Redisfs--host=localhost--port=6379--mount=/mnt/redis [--read-only] [--debug] [--prefix=skx]

Synchronization mechanism

The main reason why redisfs chose redis is to take advantage of redis's high performance and its synchronization mechanism. The author provides two methods for building two synchronous file systems:

What are the file system implementation methods of Redis storage system?

1. Use redisfs to mount different directories on two different machines to the same redis

two。 The above approach may result in at least one file system not on the same machine as Redis, resulting in unnecessary network overhead. The way shown below is to set up the master and slave Redis on different machines, and then directly use redisfs to mount the local Redis. Data synchronization is done through Redis's own synchronization mechanism, but the cost of doing so is that the file system on the corresponding Slave machine becomes read-only.

Snapshot function

Redisfs provides a snapshot of the file system. The implementation of the snapshot function is very simple. You only need to scan all the key (equivalent to file names) stored in the current Redis once and copy them to the new key. As follows:

$redisfs-snapsot--from=skx--to=copy

The above operation is to copy all the key that begins with skx to a key that begins with copy, and then use the mount parameter to build a new file system with this snapshot, as follows:

# mkdir/tmp/safe

# redisfs--prefix=copy--mount=/tmp/safe .

After reading the above, have you mastered how to implement the file system of the storage system in Redis? If you want to learn more skills or want to know more about it, you are welcome to follow the industry information channel, thank you for reading!
