Redis persistent configuration

one。 Rdb snapshot persistence

1. Configuration, configuring in redis.conf

When save 9001 # refreshes the snapshot to the hard drive, both requirements must be met before it will be triggered, that is, at least 1 keyword will change after 900 seconds.

Save 30010 # must be at least 10 keywords changed after 300 seconds.

Save 60 10000 # must be at least 10000 keywords changed after 60 seconds.

# Note the above three options are annotated, that is, persistent storage of rdb snapshots is blocked.

Stop-writes-on-bgsave-error yes # background storage error stops writing.

Rdbcompression yes # uses LZF to compress rdb files.

Rdbchecksum yes # verifies when storing and loading rdb files.

Dbfilename dump.rdb # sets the rdb file name.

Dir. / # sets the working directory to which the rdb file is written. / var/rdb can write absolute address

two。 Test performance

# Note 10,000 orders were executed

. / redis-benchmark-n 10000

two。 Aof log persistence

1. Configuration, configuring in redis.conf

Appendonly yes # whether only log yes is required (on) | no (off)

Appendfilename "appendonly.aof" # aof file location / var/aof can write an absolute address

# appendfsync no # system buffering, unified writing, high speed

# appendfsync always # system does not buffer, write directly, slow, and lose less data

Appendfsync everysec # compromise, write once per second

No-appendfsync-on-rewrite yes # is in the process of exporting rdb snapshots. Do you want to stop synchronizing aof yes (stop) | no (do not stop)

Auto-AOF-rewrite-percentage 100 # aof file size compared to the size of the last rewrite, overridden at a growth rate of 100%

Auto-AOF-rewrite-min-size 64mb # aof file, rewritten if it exceeds at least 64m
