基於docker搭建redis集群三主三從

#拉去鏡像（注：我這里拉取過了，和你們顯示的有出入）

[root@centos-linux ~]# docker pull redis

 

[root@centos-linux ~]# docker images

 

  #創建集群目錄

[root@centos-linux ~]# mkdir redis-cluster-d
[root@centos-linux ~]# cd redis-cluster-d/

#創建執行文件

[root@centos-linux redis-cluster-d]# vi redis-cluster.tmpl

文件內容

port ${PORT}

masterauth 123456

requirepass 123456

cluster-enabled yes

cluster-config-file nodes.conf

cluster-node-timeout 5000

cluster-announce-ip 127.0.0.1

cluster-announce-port ${PORT}

cluster-announce-bus-port 1${PORT}

appendonly yes

 #使用命令：在 redis-cluster下生成conf和data目標，並生成配置信息

[root@centos-linux redis-cluster-d]# for port in `seq 7001 7006`; do \
> mkdir -p ./${port}/conf \
>  && PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf \
> && mkdir -p ./${port}/data; \
> done

#后會生成一下目錄

 #創建六個redis容器

[root@centos-linux redis-cluster-d]# for port in `seq 7001 7006`; do
> docker run -d --net=host -v /root/redis-cluster-d/${port}/conf/redis.conf:/etc/redis/redis.conf -v /root/redis-cluster-d/${port}/data:/data --restart always --name=redis-${port}  redis redis-server /etc/redis/redis.conf;
> done

#進入容器

[root@centos-linux redis-cluster-d]# docker exec -it redis-7001 bash

root@centos-linux:/data# redis-cli -a 123456 --cluster create 127.0.0.1:7001 127.0.0.1:7002 127.0.0.1:7003 127.0.0.1:7004 127.0.0.1:7005 127.0.0.1:7006 --cluster-replicas 1

 #成功案例，您可以往下執行這個操作

root@centos-linux:/data# redis-cli -c -a 123456  -h 127.0.0.1  -p 7001
