首先部署redis-5.0.3，请参考我的另一篇文章
https://www.cnblogs.com/djlsunshine/p/10592174.html
启动redis服务
# redis-server /root/redis-5.0.3/redis.conf
[root@localhost ~]# redis-server /root/redis-5.0.3/redis.conf 2753:C 25 Mar 2019 22:58:01.274 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo 2753:C 25 Mar 2019 22:58:01.274 # Redis version=5.0.3, bits=64, commit=00000000, modified=0, pid=2753, just started 2753:C 25 Mar 2019 22:58:01.274 # Configuration loaded
查看进程
# ps aux | grep redis
[root@localhost ~]# ps aux | grep redis root 2754 0.0 0.4 153828 7716 ? Ssl 22:58 0:00 redis-server 192.168.2.80:6379 root 2759 0.0 0.0 112644 952 pts/1 S+ 22:58 0:00 grep --color=auto redis
创建6个节点
# mkdir cluster-test
# cd cluster-test/
# mkdir 7000 7001 7002 7003 7004 7005
[root@localhost redis-5.0.3]# mkdir cluster-test [root@localhost redis-5.0.3]# [root@localhost redis-5.0.3]# ls 00-RELEASENOTES cluster-test COPYING dump.rdb Makefile README.md runtest runtest-sentinel src utils BUGS CONTRIBUTING deps INSTALL MANIFESTO redis.conf runtest-cluster sentinel.conf tests [root@localhost redis-5.0.3]# [root@localhost redis-5.0.3]# cd cluster-test/ [root@localhost cluster-test]# [root@localhost cluster-test]# mkdir 7000 7001 7002 7003 7004 7005 [root@localhost cluster-test]# ls 7000 7001 7002 7003 7004 7005
分别在这6个节点文件夹下写入redis配置文件
以节点7000为例
port 7000 //端口7000,7002,7003 daemonize yes //redis后台运行 bind 192.168.2.80 //设置节点的IP requirepass 123456 //设置连接节点的密码 appendfilename "appendonly.aof" //aof模式持久化文件的名字（appendonly默认是no，yes就是打开aof持久化） pidfile /var/run/redis_7000.pid //pidfile文件对应7000,7002,7003 cluster-enabled yes //开启集群 cluster-config-file nodes_7000.conf //集群的配置 配置文件首次启动自动生成 7000,7001,7002 cluster-node-timeout 5000 //请求超时 设置5秒够了 appendonly yes //aof日志开启 有需要就开启，它会每次写操作都记录一条日志
启动各节点
