- 创建集群目录，修改redis.conf配置文件
cd redis-5.0.5
mkdir -p redis-cluster/6379
mkdir -p redis-cluster/6380
cp redis.conf redis-cluster/6379
cp redis.conf redis-cluster/6380

- 打包复制redis目录至其他服务器节点
cd /home/cluster
tar -zcvf redis-5.0.5.tar.gz redis-5.0.5/
# 发送至其他服务器
scp redis-5.0.5.tar.gz root@192.168.41.134:/home/cluster
scp redis-5.0.5.tar.gz root@192.168.41.135:/home/cluster

- 其他服务器解压，并修改redis.conf的bind 为当前服务器ip
tar -zxvf redis-5.0.5.tar.gz
cd redis-5.0.5
vi redis-cluster/6379/redis.conf
-----------------6379redis.conf ---------------------
bind 本机IP

vi redis-cluster/6380/redis.conf

- 各节点分别启动redis
cd redis-5.0.5/src
./redis-server /home/cluster/redis-5.0.5/redis-cluster/6379/redis.conf
./redis-server /home/cluster/redis-5.0.5/redis-cluster/6380/redis.conf
# 查看状态
ps -ef | grep redis

- 创建集群
- 注意开放防火墙端口
firewall-cmd --add-port=6379/tcp --permanent
firewall-cmd --add-port=6380/tcp --permanent
firewall-cmd --reload

- 选择一台服务器，创建集群
cd redis-5.0.5/src/
./redis-cli --cluster create 192.168.41.133:6379 192.168.41.133:6380 192.168.41.134:6379 192.168.41.134:6380 192.168.41.135:6379 192.168.41.135:6380 --cluster-replicas 1
# 出现下图集群部署成功

- 后续重启只需要启动节点即可
cd redis-5.0.5/src
./redis-server /home/cluster/redis-5.0.5/redis-cluster/6379/redis.conf
./redis-server /home/cluster/redis-5.0.5/redis-cluster/6380/redis.conf

- 如果需要删除集群重新创建,需要删除数据文件，任意一个节点执行 cluster flushslots 。删除各个Redis安装目录下的节点配置文件nodes.conf、数据文件dump.rdb
