Build Redis

Simple as make under the redis root folder

Run Redis

after build:

cd redis/src
./redis-server

Install Redis

Install Redis into /usr/local/bin environment

cd utils
./install_server.sh

Redis CLI

Redis doesn’t have web ui, you need use command line tools to connect to redis (usually localhost:6379)

cd redis/src
./redis-cli
127.0.0.1:6379> set name r0ngsh3n
OK
127.0.0.1:6379> get name 
"r0ngsh3n"

Redis basic commands

show system info

in ./redis-cli shell:

info
info [keyword]  keyword could be: keyspace, memory, CPU etc

but you also can use command line:

./redis-cli INFO

show all the available databases

127.0.0.1:6379> config get databases
1) "databases"
2) "16"
127.0.0.1:6379> 

This showed that redis has 16 databases available in redis

change database

by default, it point at “0” database (index), but you can change the database by using select command:

127.0.0.1:6379> select 10
OK
127.0.0.1:6379[10]> 

This change database to 10

Jedis + Redis

Jedis is the old Redis client, it support most of Redis commands, but it is synchronize process, and use block I/O.

in build.gradle, add Jedis dependency:

    implementation 'redis.clients:jedis:4.1.0'

then write your code:

   public static void main(String[] args){
        JedisPooled jedis = new JedisPooled("localhost", 6379);
        jedis.set("your_name", "hello_world");
        String value = jedis.get("your_name");

    }

Redisson + Redis

Lettuce + Redis

SpringBoot + RedisTemplate + Redis

SpringBoot + Jedis + Redis

Jedis can be integrated into SpringBoot project just 3 steps:

1. Define the yaml/propertie of Jedis
2. Define the config java class of Jedis

3. Redis Data type
