6. Start the test:

# /opt/redis# nohup src/redis-server redis.conf &

# ps-ef|grep redis

# /usr/local/redis/bin/redis-cli ping

7, testing:

Creation is performed on the main service 103:

# /usr/local/redis/bin/redis-cli -h 172.16.15.103 -a 1qaz@WSX

>set test 123456

View from Service 104:

# /usr/local/redis/bin/redis-cli -h 172.16.15.104

>get test

performance test

# /usr/local/redis/bin/redis-benchmark

close the service

# /usr/local/redis/bin/redis-cli -p 6379 shutdown

Forcefully flushing data to disk [Redis defaults to asynchronous writing to disk]

# /usr/local/redis/bin/redis-cli -p 6379 save

Redis Fuzzy Search

keys *

select 2

Deleting all keys that start with user can be done like this:

# redis-cli keys "user*"

1) "user1"

2) "user2"

# redis-cli keys "user*" | xargs redis-cli del

(integer) 2

#Delete successfully

#Batch delete matching wildcard keys using Linux pipes and xargs parameters:

redis-cli keys "s*" | xargs redis-cli del

#If you need to make a database, you need to use the-n database number parameter, the following is to delete the key starting with s in the 2 database:

redis-cli -n 2 keys "s*" | xargs redis-cli -n 2 del

redis-cli keys "*" | xargs redis-cli del

#If redis-cli is not set as a system variable, specify the full path to redis-cli

#Example: /opt/redis/redis-cli keys "*"| xargs /opt/redis/redis-cli del

Delete all keys in the current database

flushdb

Delete all database keys

flushall
