1、下载安装

Hint: It's a good idea to run 'make test' ;)

[root@ip101 redis-5.0.4]# ls #安装了bin工具文件夹
00-RELEASENOTES bin BUGS CONTRIBUTING COPYING deps INSTALL Makefile MANIFESTO README.md redis.conf runtest runtest-cluster runtest-sentinel sentinel.conf src tests utils
2、创建相关文件夹
[root@ip101 redis-5.0.4]# mkdir -p /opt/app/redis-5.0.4/cluster/6379
[root@ip101 redis-5.0.4]# mkdir -p /opt/app/redis-5.0.4/cluster/6380
[root@ip101 redis-5.0.4]# pwd
/opt/app/redis-5.0.4
[root@ip101 redis-5.0.4]# ls
00-RELEASENOTES BUGS CONTRIBUTING deps Makefile README.md runtest runtest-sentinel src utils
bin cluster COPYING INSTALL MANIFESTO redis.conf runtest-cluster sentinel.conf tests
[root@ip101 redis-5.0.4]# pwd
/opt/app/redis-5.0.4
[root@ip101 redis-5.0.4]# cp redis.conf /opt/app/redis-5.0.4/cluster/6379
[root@ip101 redis-5.0.4]# cp redis.conf /opt/app/redis-5.0.4/cluster/6380
[root@ip101 redis-5.0.4]#
3、vi /opt/app/redis-5.0.4/cluster/6379/redis.conf
# 绑定服务器IP地址
bind 192.168.8.101
# 绑定端口号，必须修改，以此来区分Redis实例
port 6379
# 后台运行
daemonize yes
# 修改pid进程文件名，以端口号命名
pidfile /var/run/redis-6379.pid
# 修改日志文件名称，以端口号为目录来区分
logfile /opt/app/redis-5.0.4/cluster/6379/redis.log
# 修改数据文件存放地址，以端口号为目录名来区分
dir /opt/app/redis-5.0.4/cluster/6379/
# 启用集群
cluster-enabled yes
# 配置每个节点的配置文件，同样以端口号为名称
cluster-config-file nodes-6379.conf
# 配置集群节点的超时时间，可改可不改
cluster-node-timeout 15000
# 启动AOF增量持久化策略
appendonly yes
# 发生改变就记录日志
appendfsync always
vi /opt/app/redis-5.0.4/cluster/6380/redis.conf
# 绑定服务器IP地址
bind 192.168.8.101
# 绑定端口号，必须修改，以此来区分Redis实例
port 6380
# 后台运行
daemonize yes
# 修改pid进程文件名，以端口号命名
pidfile /var/run/redis-6380.pid
# 修改日志文件名称，以端口号为目录来区分
logfile /opt/app/redis-5.0.4/cluster/6380/redis.log
# 修改数据文件存放地址，以端口号为目录名来区分
dir /opt/app/redis-5.0.4/cluster/6380/
# 启用集群
cluster-enabled yes
# 配置每个节点的配置文件，同样以端口号为名称
cluster-config-file nodes-6380.conf
# 配置集群节点的超时时间，可改可不改
cluster-node-timeout 15000
# 启动AOF增量持久化策略
appendonly yes
# 发生改变就记录日志
appendfsync always
4、ip102，ip103仿效ip101进行安装和配置
# 绑定服务器IP地址
bind 192.168.8.102
---------------
# 绑定服务器IP地址
bind 192.168.8.102
5、ip101，ip102，ip103配置环境变量
export REDIS_HOME=/opt/app/redis-5.0.4
export PATH=$REDIS_HOME/bin:$PATH
source /etc/profile
6、ip101、ip102、ip103启动redis
[root@ip101 redis-5.0.4]# redis-server /opt/app/redis-5.0.4/cluster/6379/redis.conf
[root@ip101 redis-5.0.4]# redis-server /opt/app/redis-5.0.4/cluster/6380/redis.conf
[root@ip101 redis-5.0.4]# ps aux|grep redis

root 12343 0.0 0.0 112660 976 pts/0 S+ 05:01 0:00 grep --color=auto redis
[root@ip101 redis-5.0.4]#
7、创建集群
redis-cli --cluster create 192.168.8.101:6379 192.168.8.101:6380 192.168.8.102:6379 192.168.8.102:6380 192.168.8.103:6379 192.168.8.103:6380 --cluster-replicas 1

8、查看集群状态
[root@ip101 redis-5.0.4]# redis-cli --cluster check 192.168.8.101:6379
192.168.8.101:6379 (3784c7f8...) -> 0 keys | 5461 slots | 1 slaves.
192.168.8.102:6379 (dfb1bf05...) -> 0 keys | 5462 slots | 1 slaves.
192.168.8.103:6379 (a88b9d61...) -> 0 keys | 5461 slots | 1 slaves.
[OK] 0 keys in 3 masters.
0.00 keys per slot on average.

9、使用集群
随意找到一个端口进行连接
[root@ip101 redis-5.0.4]# redis-cli -c -h 192.168.8.102 -p 6380
192.168.8.102:6380> set key1 value1
-> Redirected to slot [9189] located at 192.168.8.102:6379
OK
192.168.8.102:6379> get key1
"value1"
192.168.8.102:6379>
