將redis配置爲緩存

Question

我想將redis純粹用作緩存。爲確保如此，我必須在redis.conf中禁用哪些選項。我讀了默認情況下redis持久數據（AOF和rdb文件，也許更多）。即使設置爲過期的鍵也是如此。 是否堅持被設置爲過期的數據是矛盾的？

Answer 1

Redis將其所有數據存儲在RAM中，但不時將其轉儲到持久存儲（HDD/SDD）。這個過程被稱爲快照。

你可以在your redis.conf file配置快照的頻率（見SNAPSHOTTING部分）：

# save <seconds> <changes> 
# 
# Will save the DB if both the given number of seconds and the given 
# number of write operations against the DB occurred. 
# 
# In the example below the behaviour will be to save: 
# after 900 sec (15 min) if at least 1 key changed 
# after 300 sec (5 min) if at least 10 keys changed 
# after 60 sec if at least 10000 keys changed 
# 
# Note: you can disable saving completely by commenting out all "save" lines. 
# 
# It is also possible to remove all the previously configured save 
# points by adding a save directive with a single empty string argument 
# like in the following example: 
# 
# save "" 

save 900 1 
save 300 10 
save 60 10000 

所以，如果你想完全禁用快照，您應該刪除或redis.conf文件發表評論所有save指令。
