redis5集群搭建（没有ruby操作，没有坑）

1,官网下载redis5，并make编译，并执行make test是否ok，无问题执行下一步。
2,创建下面内容的模板文件redis-cluster.tmpl
port ${PORT}
protected-mode no
cluster-enabled yes
cluster-config-file nodes.conf
cluster-node-timeout 5000
cluster-announce-ip 你电脑的ip
cluster-announce-port ${PORT}
cluster-announce-bus-port 1${PORT}
appendonly yes

3,根据模板文件，执行shell生成目标配置文件

for port in `seq 8000 8005`
do
mkdir -p ./${port}/conf && PORT=${port} envsubst < ./redis-cluster.tmpl > ./${port}/conf/redis.conf && mkdir -p ./${port}/data
done

4,根据配置文件，执行下面shell命令启动6个节点的redis
for port in `seq 8000 8005`
do
    cd ${port} && /root/software/redis-5.0.5/src/redis-server ./conf/redis.conf &
done

如果有报错，查看原因解决，否则进行下一步

 

5,执行生成集群的命令
/root/software/redis-5.0.5/src/redis-cli --cluster create 172.16.0.9:8000 172.16.0.9:8001 172.16.0.9:8002 172.16.0.9:8003 172.16.0.9:8004 172.16.0.9:8005 --cluster-replicas 1

注：172.16.0.9是内网ip，改成外网ip（即你电脑的ip）应该也可以,

6,正常情况下可以看到如下打印：
