基于docker搭建redis集群三主三从
#拉去镜像（注：我这里拉取过了，和你们显示的有出入）
[root@centos-linux ~]# docker pull redis
[root@centos-linux ~]# docker images
#创建集群目录
[root@centos-linux ~]# mkdir redis-cluster-d
[root@centos-linux ~]# cd redis-cluster-d/
#创建执行文件
[root@centos-linux redis-cluster-d]# vi redis-cluster.tmpl
文件内容
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目标，并生成配置信息
[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
#后会生成一下目录
#创建六个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
#进入容器
[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，您可以往下执行这个操作

#下面标记红的waiting一直停不下来，说明创建集群的ip和redis.conf的ip对不上
去往学习的路上，请多多指教。。。。
