Redis 分布式集群能解决的问题	集群概念
解决现有系统单节点并发压力和物理上限问题	通过添加服务器的数量，提供相同的服务，从而让服务器达到一个稳定、高效的状态

一、节点分布总览

演示案例
3主3从横向扩展

服务器	端口	节点说明
192.168.0.114	7001	master
192.168.0.114	7002	master
192.168.0.114	7003	master
192.168.0.114	8001	slave
192.168.0.114	8002	slave
192.168.0.114	8003	slave

二、软件配置初始化

下载

wget

解压

cd /app
tar

编译安装

cd redis-6.2.6/
make install

配置抽离

mkdir /app/redis-cluster/
cp

编辑配置

vim

修改配置7处：
bind 127.0.0.1 改为 bind 0.0.0.0 port 6379 改为 port 7001 daemonize no 改为 daemonize yes pidfile /var/run/redis_6379.pid 改为 pidfile /var/run/redis_7001.pid
注释打开cluster-enabled yes
注释打开 cluster-node-timeout 15000
注释打开 nodes-6379.conf 改为nodes-7001.conf
集群配置分配

将/app/redis-cluster/redis.conf复制6份并重命名

cd app/redis-cluster/
cp redis.conf redis-7001.conf
cp redis.conf redis-7002.conf
cp redis.conf redis-7003.conf
cp redis.conf redis-8001.conf
cp redis.conf redis-8002.conf
cp

三、集群配置修改

分别修改redis-7002.conf、redis-7003.conf、redis-8001.conf、redis-8002.conf、redis-8003.conf

3.1. redis-7002.conf

vim

port 把7001 修改为7002 将7001.pid 修改为 7002.pid
将nodes-7001.conf 修改为 nodes-7002.conf

3.2. redis-7003.conf

vim

port 把7001 修改为7003 将7001.pid 修改为 7003.pid
将nodes-7001.conf 修改为 nodes-7003.conf

3.3. redis-8001.conf

vim

port 把7001 修改为8001 将7001.pid 修改为 8001.pid
将nodes-7001.conf 修改为 nodes-8001.conf

3.4. redis-8002.conf

vim

92行 port 把7001 修改为8002 将7001.pid 修改为 8002.pid
将nodes-7001.conf 修改为 nodes-8002.conf

3.5. redis-8003.conf

vim

port 把7001 修改为8003 将7001.pid 修改为 8003.pid
将nodes-7001.conf 修改为 nodes-8003.conf

3.6. redis启动

/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-7001.conf
/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-7002.conf
/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-7003.conf
/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-8001.conf
/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-8002.conf
/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-8003.conf

查看进程：

ps -ef |grep

操作日志如下：

[root@localhost ~]# ps -ef |grep redis
root       7770      1  0 11:29 ?        00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:7001 [cluster]
root       7775      1  0 11:29 ?        00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:7002 [cluster]
root       7780      1  0 11:29 ?        00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:7003 [cluster]

root       7790      1  0 11:29 ?        00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:8002 [cluster]
root       7795      1  0 11:29 ?        00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:8003 [cluster]
root       7800   7404  0 11:29 pts/1    00:00:00 grep --color=auto redis
[root@localhost ~]#

四、节点握手

上面仅仅是搭建了集群，6个节点之间还没有关系，下面通过节点握手让集群各节点之间，发生关系。

4.1. 节点握手

7001节点，依次执行（一条一条复制粘贴）以下命令：

/app/redis-6.2.6/src/redis-cli -h localhost -p 7001
cluster meet 192.168.0.114 7002
cluster meet 192.168.0.114 7003
cluster meet 192.168.0.114 8001
cluster meet 192.168.0.114 8002
cluster meet 192.168.0.114 8003

4.2. 操作日志如下：

[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 7001
localhost:7001> cluster meet 192.168.0.114 7002
OK
localhost:7001> cluster meet 192.168.0.114 7003
OK
localhost:7001> cluster meet 192.168.0.114 8001
OK
localhost:7001> cluster meet 192.168.0.114 8002
OK
localhost:7001> cluster meet 192.168.0.114 8003
OK
localhost:7001>

五、槽位分配和配置主从

5.1. 槽位分配

/app/redis-6.2.6/src/redis-cli -h localhost -p 7001 cluster addslots {0..5461}
/app/redis-6.2.6/src/redis-cli -h localhost -p 7002 cluster addslots {5462..10922}
/app/redis-6.2.6/src/redis-cli -h localhost -p 7003 cluster addslots {10923..16383}

操作日志：
[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 7001 cluster addslots {0..5461}
OK
[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 7002 cluster addslots {5462..10922}
OK
[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 7003 cluster addslots {10923..16383}
OK
[root@localhost ~]#

登录7001节点
/app/redis-6.2.6/src/redis-cli -h localhost -p 7001
查看集群信息:cluster info
查看节点信息:cluster nodes

操作日志：
[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 7001
localhost:7001> cluster info

localhost:7001>


注：目前都是master，节点信息等会要用，这个窗口先不要关闭，
在新开一个窗口，进行下一步操作

5.2. 主从复制分配

复制原则：8001复制7001、8001复制7001、8003复制7003

/app/redis-6.2.6/src/redis-cli -h localhost -p 8001 cluster replicate fd35850bf465cb53b0ffc8f843078c171d14583d
/app/redis-6.2.6/src/redis-cli -h localhost -p 8002 cluster replicate 72e1d44ffa3b20f17ba6abb3aa8df3a9752e00cc
/app/redis-6.2.6/src/redis-cli -h localhost -p 8003 cluster replicate 3523d3510e7a551929729798f5ea0e9b65d85eea

操作日志如下：

[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 8001 cluster replicate fd35850bf465cb53b0ffc8f843078c171d14583d
localhost -p 8003 cluster replicate 3523d3510e7a551929729798f5ea0e9b65d85eeaOK
[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 8002 cluster replicate 72e1d44ffa3b20f17ba6abb3aa8df3a9752e00cc
OK
[root@localhost ~]# /app/redis-6.2.6/src/redis-cli -h localhost -p 8003 cluster replicate 3523d3510e7a551929729798f5ea0e9b65d85eea
OK
[root@localhost ~]#

5.3. 集群验证

登录7001节点

/app/redis-6.2.6/src/redis-cli -h localhost -p 7001

查看集群信息:cluster info
查看节点信息:cluster nodes

注：目前3主3从当主节点挂掉之后，从节点自动上位
操作日志如下：
