Redis 多机多节点集群搭建方案（5.0版本）

>搭建环境：

a)redis的安装包，redis-5.0.8.tar.gz

b)gcc安装包gcc_rpm.tar.gz

c)VM10

d)CentOS镜像文件

>搭建步骤：

1、准备工作：

（1）在linux下新建一个存储集群的目录redis-cluster：

（2）检查是否安装gcc：

2、解压编译安装一个Redis服务

（1）将redis-5.0.8.tar.gz放到目录下

（2）解压：tar xzf redis-5.0.8.tar.gz

（3）进入目录：cd redis-5.0.8

（4）编译安装：make install PREFIX=/home/dareway/redis-cluster/redis-5.0.8

（5）修改配置文件（说明可见：https://blog.csdn.net/AhaQianxun/article/details/107014991）：

启动服务：

[dareway@localhost redis-cluster]$ ./redis-5.0.8/bin/redis-server ./redis-5.0.8/redis.conf
1744:C 28 Jun 2020 19:34:08.081 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo
1744:C 28 Jun 2020 19:34:08.081 # Redis version=5.0.8, bits=64, commit=00000000, modified=0, pid=1744, just started
1744:C 28 Jun 2020 19:34:08.081 # Configuration loaded

查看进程可以看到在6379默认端口：

[dareway@localhost redis-cluster]$ ps -ef|grep redis
dareway    1745      1  0 19:34 ?        00:00:00 ./redis-5.0.8/bin/redis-server *:6379
dareway    1750   1510  0 19:34 pts/0    00:00:00 grep --color=auto redis

使用redis-cli 连接测试：

[dareway@localhost redis-cluster]$ ./redis-5.0.8/bin/redis-cli
127.0.0.1:6379>

可以使用Jdis客户端连接：

     // jedisJedis jedis = new Jedis("192.168.79.129", 6379);jedis.auth("123456");jedis.set("name", "redis-value");String value = jedis.get("name");System.out.println(value);jedis.close();

出现问题：连接超时

这里绑定了本机，我们把这个备注掉；

# bind 127.0.0.1

配置完后

[root@localhost redis]# ./bin/redis-cli shutdown

[root@localhost redis]# ./bin/redis-server ./redis.conf

要重启下redis服务；

又出现问题：远程连接Redis自我保护

Exception in thread "main" redis.clients.jedis.exceptions.JedisDataException: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside.at redis.clients.jedis.Protocol.processError(Protocol.java:127)at redis.clients.jedis.Protocol.process(Protocol.java:161)at redis.clients.jedis.Protocol.read(Protocol.java:215)at redis.clients.jedis.Connection.readProtocolWithCheckingBroken(Connection.java:340)at redis.clients.jedis.Connection.getStatusCodeReply(Connection.java:239)at redis.clients.jedis.BinaryClient.connect(BinaryClient.java:96)at redis.clients.jedis.Connection.sendCommand(Connection.java:126)at redis.clients.jedis.Connection.sendCommand(Connection.java:117)at redis.clients.jedis.BinaryClient.auth(BinaryClient.java:564)at redis.clients.jedis.BinaryJedis.auth(BinaryJedis.java:2138)at com.dareway.test.RedisConnTest.main(RedisConnTest.java:16)

有两种方法解决

第一种直接去掉自我保护功能（不推荐）

[root@localhost redis]# vi /usr/local/redis/redis.conf

进入配置

找到 protected-mode yes 改成 no即可

第二种设置redis连接密码

进入客户端

[root@localhost redis]# ./bin/redis-cli

127.0.0.1:6379> config set requirepass 123456

设置密码 123456

127.0.0.1:6379> quit

[root@localhost redis]# ./bin/redis-cli

127.0.0.1:6379> auth 123456

再测试一下，可以了

3、多机多节点Redis集群搭建（3主 + 6从）

克隆三台CentOS虚拟机，分别在每台虚拟机上8001-8003端口创建三个节点，注意要修改配置。

在每台机器redis-cluster目录下，mkdir 8001 8002 8003，可以从上面安装过的6379拷贝配置文件到文件夹下分别进行修改，也可以将整个5.0目录分别拷贝到8001-8003。

（1）分别修改配置（参考自己实际的IP和端口进行调整配置）：

port 7001  //六个节点配置文件分别是7001-7003bind 192.168.79.129    //默认ip为127.0.0.1 需要改为其他节点机器可访问的ip 否则创建集群时无法访，和单机集群有区别daemonize yes        //redis后台运行pidfile /var/run/redis_7001.pid   //pidfile文件对应7001-7003cluster-enabled yes   //开启集群cluster-config-file nodes_7001.conf  //保存节点配置，自动创建，自动更新对应7001-7003cluster-node-timeout 5000    //集群超时时间，节点超过这个时间没反应就断定是宕机appendonly yes   //存储方式，aof，将写操作记录保存到日志中dbfilename dump_7001.rdb

补充配置：masterauth xxx //设置集群节点间访问密码

（2）分别启动多个节点：

[dareway@localhost redis-cluster]$ ps -ef|grep redis
dareway    2146      1  0 20:03 ?        00:00:00 ./8001/redis-5.0.8/bin/redis-server 192.168.79.129:8001 [cluster]
dareway    2151      1  0 20:04 ?        00:00:00 ./8002/redis-5.0.8/bin/redis-server 192.168.79.129:8002 [cluster]
dareway    2156      1  0 20:04 ?        00:00:00 ./8003/redis-5.0.8/bin/redis-server 192.168.79.129:8003 [cluster]
dareway    2162   1510  0 20:04 pts/0    00:00:00 grep --color=auto redis

（3）开放集群端口或者直接干掉防火墙

systemctl stop firewalld.service

（4）通过redis-cli 命令创建集群

./redis-5.0.8/bin/redis-cli --cluster create 192.168.79.129:8001 192.168.79.130:8001 192.168.79.131:8001 192.168.79.129:8002 192.168.79.129:8003 192.168.79.130:8002 192.168.79.130:8003 192.168.79.131:8002 192.168.79.131:8003 --cluster-replicas 2 -a 123456

2代表一个master有2个slave，前三个ip是master。

补充：如果未设置密码无需 -a xxxxxx 命令

运行结果：

[root@localhost redis-cluster]# systemctl stop firewalld.service
[root@localhost redis-cluster]# ./redis-5.0.8/bin/redis-cli --cluster create 192.168.79.129:8001 192.168.79.130:8001 192.168.79.131:8001 192.168.79.129:8002 192.168.79.129:8003 192.168.79.130:8002 192.168.79.130:8003 192.168.79.131:8002 192.168.79.131:8003 --cluster-replicas 2

显示分配哈希槽，启动成功，可以用了。

（5）验证连接：

./redis-cli -h 10.1.50.207 -c -p 8001 -a redis123（-a访问服务端密码，-c表示集群模式，指定ip地址和端口号）

cluster info查看集群信息

./redis-cli --cluster info 10.1.50.208:8001 -a redis123检查集群状态

[root@localhost redis-cluster]# ./redis-5.0.8/bin/redis-cli -h 192.168.79.130 -c -p 8001
192.168.79.130:8001> cluster info

lettuce客户端连接测试：

RedisURI redisUri = RedisURI.builder().withHost("192.168.79.129").withPort(8001).withTimeout(Duration.of(60, ChronoUnit.SECONDS)).build();RedisClient redisClient = RedisClient.create(redisUri);StatefulRedisConnection<String, String> connection = redisClient.connect();// 创建线程安全的连接RedisCommands<String, String> redisCommands = connection.sync();String result = redisCommands.set("RedisLettuce-01", "RedisLettuce-01");System.out.println(result);System.out.println(redisCommands.get("RedisLettuce-01"));connection.close();redisClient.shutdown();

搭建完成！
