Redis installation and testing in centos6.9

1. Install gcc, redis compilation requires c language related environment, gcc belongs to c/c++ compiler
yum -y install gcc gcc-c++ libstdc++-devel tcl -y

2. Download the installation package (version 4.0.9 can be modified by yourself)

wget http://download.redis.io/releases/redis-4.0.9.tar.gz
tar -zxvf redis-4.0.9.tar.gz -C ../servers
cd /export/servers/
mv redis-4.0.9 redis

3. Compile redis

cd /export/servers/redis/
make MALLOC=libc
make PREFIX=/usr/local/redis install

4. Prepare the configuration file

cd /usr/local/redis/bin/
cd /usr/local/redis
mkdir conf
cd conf
vi redis_6379.conf

The content of the configuration file is as follows:

bind 127.0.0.1(用当前机器的ip地址替代)
protected-mode yes
port 6379
tcp-backlog 511
timeout 0
tcp-keepalive 300

loglevel notice
logfile "/export/data/redis/6379/log.log"
databases 16

save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes

rdbchecksum yes
dbfilename dump.rdb

zset-max-ziplist-value 64
hll-sparse-max-bytes 3000

client-output-buffer-limit normal 0 0 0
client-output-buffer-limit slave 256mb 64mb 60
client-output-buffer-limit pubsub 32mb mb 60
hz 10
aof-rewrite-incremental-fsync yes

5. Start the service

mkdir -p /export/data/redis/6379/
cd /usr/local/redis/bin/
./redis-server ../conf/redis_6379.conf

6. Use the client to connect

cd /usr/local/redis/bin/
./redis-cli（连接不上，那就 ./redis-cli -h 主机ip地址）

7. Test

127.0.0.1>ping
如果返回PONG的话就意味着响应成功

8. Test with Java code

8.1 Add pom dependencies

<dependency>
    <groupId>redis.clients</groupId>
    <artifactId>jedis</artifactId>
    <version>2.9.0</version>
</dependency>

8.2 Writing main method tests

public class RedisTest {

    public static void main(String[] args) {
        // 操作之前保证redis服务启动,第一个参数为安装redis所在主机的ip，第二个参数为默认端口
        Jedis jedis = new Jedis("192.168.60.129", 6379);
        String pong = jedis.ping();
        System.out.println(pong);
        // 测试string set get map 
        jedis.set("name", "小明");
        String name = jedis.get("name");
        System.out.println(name);
        jedis.hset("mymap", "k1", "v1");
        String hget = jedis.hget("mymap", "k1");
        System.out.println(hget);
        Set<String> hkeys = jedis.hkeys("mymap");
        System.out.println("hkeys: " + hkeys);

        // list
        jedis.lpush("mylist", "a", "b", "c");
        jedis.rpush("mylist", "a", "b", "c");
        List<String> lrange = jedis.lrange("mylist", 0, -1);
        for (String string : lrange) {
            System.out.println(string);
        }


    }

}
