This article will explain in detail the sample analysis of the basic configuration of redis. The editor thinks it is very practical, so I share it for you as a reference. I hope you can get something after reading this article.

Redis ms master-slave cluster functions: 1, master-slave backup to prevent downtime 2, read-write separation, sharing master tasks 3, task separation

Redis's MS synchronization principle: MS automatically connects, S initiates synchronization, M begins to DUMP out RDB,S to receive M's RDB and stores it in its own memory. In the process of M doing DUMP, new data is generated. M will buffer the new data into AOF. When M finishes DUMP, it also sends AOF to SLAVE to complete a synchronization.

There are two ways to persist Redis: RDB and AOF

Configuration options for Rdb Snapshot

If there is one write in save 9001 / 900, a snapshot is generated.

Save 1000 / / if there are 1000 writes in 300 seconds, a snapshot is generated

Save 60 10000 / / if there are 10000 writes in 60 seconds, a snapshot is generated

(if all three options are masked, rdb is disabled)

When there is an error in the stop-writes-on-bgsave-error yes / / background backup process, does the main process stop writing?

Whether the exported rdb file of rdbcompression yes / / is compressed

Rdbchecksum yes / / when importing rbd recovery data, do you want to verify the integrity of rdb?

Dbfilename dump.rdb / / exported rdb file name

The placement path of dir. / rdb

Configuration of Aof

Appendonly no # whether to turn on aof logging function

Appendfsync always # every command is immediately synchronized to aof. Safe, slow

Appendfsync everysec # compromise, write once per second

Appendfsync no # write work to the operating system, the operating system to determine the size of the buffer, unified write to aof. Low synchronization frequency and high speed

No-appendfsync-on-rewrite yes: # do you want to stop synchronizing aof while exporting rdb snapshots?

Auto-aof-rewrite-percentage 100 # aof file size compared to the size of the last rewrite, when the growth rate is 100%, rewrite

Auto-aof-rewrite-min-size 64mb # aof file, overridden when it exceeds at least 64m
