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
