V2.2.6

II. Installation & compilation

The following installation is all completed in the specified directory, you can choose a suitable unified directory for software installation and management.

2.1 download plug-in package wget https://github.com/RedisLabsModules/rebloom/archive/v2.2.6.tar.gz2.2 extract tar-zxvf v2.2.6.tar.gz2.3 compilation plug-in cd RedisBloom-2.2.6/make

After compiling successfully, you can see the redisbloom.so file.

III. Redis Integration 3.1 Redis configuration file modification

Add the address of the redisbloom.so file such as RedisBloom to the redis.conf configuration file

If it is a cluster, the address of the redisbloom.so file needs to be added to each configuration file.

You need to restart redis after adding.

Loadmodule / usr/local/soft/RedisBloom-2.2.6/redisbloom.so

The configuration items of loadmodule are preset in the redis.conf configuration file, which can be modified directly here, and it will be more convenient to modify them later. \

3.2 whether the test was successful

The main instructions for the Redis integrated Bloom filter are as follows:

Bf.add add an element

Bf.exists determines whether an element exists or not

Bf.madd adds multiple elements

Bf.mexists determines whether multiple elements exist or not

Connect the client to test, and if the instruction is valid, it proves that the integration is successful.

If the following situation occurs (error) ERR unknown command, you can check it by the following methods:

SHUTDOWN Redis instance, restart the instance, and test again

Check that the configuration file is configured with the correct redisbloom.so file address

Check whether the version of Redis is too low
