1、打开https://redis.io/在Download it下面直接点击“Redis 5.0.3 is the latest stable version.”下载redis-5.0.3.tar.gz然后传到centos系统
2、安装c++编译器（视网速快慢可能会等待很久）
# yum install gcc-c++
Is this ok [y/N]:y
Is this ok [y/N]:y
3、把redis-5.0.3.tar.gz复制到/usr/local/ 并开始编译→安装→启动redis
# mv /root/Downloads/redis-5.0.3.tar.gz /usr/local/
# cd /usr/local/
# tar -zxvf redis-5.0.3.tar.gz
# cd redis-5.0.3
# make
# make PREFIX=/usr/local/redis/ install
# cp redis.conf /usrl/local/redis
# cd /usr/local/redis/
# vim redis.conf
/daemonize
--把daemonize no 改成daemonize yes （这样才能让redis在后台运行，而不会因为命令行语句的输入导致中断redis线程）
/bind 127.0.0.1
--注释掉这一行#bind 127.0.0.1
/protected-mode yes
--把no改成no
:wq
[root#localhost redis]# ./bin/redis-cli shutdown
[root#localhost redis]# ./bin/redis-server ./redis.conf
4、查看redis是否运行
# ps -ef | grep -i redis
5、开启redis端口6379
# vim /etc/sysconfig/iptables
复制-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT这一行
然后把端口22改成6379（vim命令：复制当前行yy，粘贴p）
-A INPUT -m state --state NEW -m tcp -p tcp --dport 6379 -j ACCEPT
:wq
# service iptables restart
6、进入redis命令行
[root#localhost redis]# ./bin/redis-cli --raw
127.0.0.1:6379> set keyname keyvalue
127.0.0.1:6379> KEYS *
127.0.0.1:6379> get keyname
127.0.0.1:6379> del keyname
7、设置redis自动启动 https://blog.csdn.net/qq_37860634/article/details/87363180

【JAVA连接、使用redis】
1、在POM.xml引入依赖包
<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-pool2 -->
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
<version>2.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/redis.clients/jedis -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>2.7.0</version>
</dependency>
2、测试代码
public class Test {
public static void main(String[] args) {
testRedis1();
testRedis2();
}
public static void testRedis1() {
Jedis jedis = new Jedis( "192.168.244.138", 6379 );//IP地址记得改成自己的
jedis.set( "name", "舒工1" );
String name = jedis.get( "name" );
System.out.println( name );
jedis.close();
}
public static void testRedis2() {
JedisPoolConfig config = new JedisPoolConfig();
config.setMaxTotal( 30 );
config.setMaxIdle( 10 );
JedisPool jedisPool = new JedisPool( config, "192.168.244.138", 6379 );//IP地址记得改成自己的
Jedis jedis = null;
try {
jedis = jedisPool.getResource();
jedis.set( "name", "舒工2" );
String name = jedis.get( "name" );
System.out.println( name );
} catch (Exception e) {
e.printStackTrace();
} finally {
if (jedis != null) jedis.close();
if (jedisPool != null) jedisPool.close();
}
}
}
