Centos7 redis 5.0.5 集群简单搭建

tar -zxvf  redis-5.0.5.tar.gz

安装

 make

创建集群目录 redis-cluster 并新增 7001-7006空文件夹

将 redis-5.0.5/redis.conf 复制一份到 7001文件夹下

cp -a  /usr/local/redis-5.0.5/redis.conf  /usr/local/redis-cluster/7001

修改7001目录下redis.conf
1.端口

 port 7001

2.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问对应的端口，无法创建集群 远程服务器修改为 0.0.0.0

bind 0.0.0.0

3.外网可以访问

protected-mode no

4.redis后台运行

daemonize yes

5.pidfile文件对应70001

pidfile /var/run/redis_7001.pid

6.开启集群，把注释#去掉

cluster-enabled yes

7.集群的配置，配置文件首次启动自动生成 7001

cluster-config-file nodes_7001.conf

8.请求超时，默认15秒，可自行设置

cluster-node-timeout 15000

9.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

appendonly yes

10.设置密码

masterauth  password123321 

requirepass password123321

OK 保存
将7001/redis.conf 各复制一份到 7002-7006,修改每一份 redis.conf 对应port(上面的第1 5 7 三条)
集群中的节点启动

/usr/local/redis-5.0.5/src/redis-server /usr/local/redis-c/7001/redis.conf
/usr/local/redis-5.0.5/src/redis-server /usr/local/redis-c/7002/redis.conf
/usr/local/redis-5.0.5/src/redis-server /usr/local/redis-c/7003/redis.conf
/usr/local/redis-5.0.5/src/redis-server /usr/local/redis-c/7004/redis.conf
/usr/local/redis-5.0.5/src/redis-server /usr/local/redis-c/7005/redis.conf
/usr/local/redis-5.0.5/src/redis-server /usr/local/redis-c/7006/redis.conf

出现如下信息
出现以下信息，表示启动成功：

15025:C 05 May 2020 11:08:19.801 # oO0OoO0OoO0Oo Redis is starting oO0OoO0OoO0Oo

创建集群

[root@VM_0_6_centos redis-5.0.5]# ./src/redis-cli --cluster create  你的公网ip:7001 你的公网ip:7002 你的公网ip:7003 你的公网ip:7004 你的公网ip:7005 你的公网ip:7006  --cluster-replicas 1 -a password123321

其中 -a password123321 是redis.conf中自己设置的密码
