docker-compose 搭建 redis 集群

准备配置文件

bind 0.0.0.0

# redis端口

port ${PORT}

requirepass redispwd

# 关闭保护模式

protected-mode no

# 开启集群

cluster-enabled yes

# 集群节点配置

cluster-config-file nodes.conf

# 超时

cluster-node-timeout 5000

# 集群节点IP host模式为宿主机IP

cluster-announce-ip 这里放宿主机ip

# 集群节点端口 7001 - 7006

cluster-announce-port ${PORT}

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

# 开启 appendonly 备份模式

appendonly yes

# 每秒钟备份

appendfsync everysec

# 对aof文件进行压缩时，是否执行同步操作

no-appendfsync-on-rewrite no

# 当目前aof文件大小超过上一次重写时的aof文件大小的100%时会再次进行重写

auto-aof-rewrite-percentage 100

# 重写前AOF文件的大小最小值 默认 64mb

auto-aof-rewrite-min-size 64mb

集群节点文件生成

for port in `seq 7001 7006`; do \

  mkdir -p ./redis-cluster/${port}/conf \

  && PORT=${port} envsubst < ./redis.conf > ./redis-cluster/${port}/conf/redis.conf \

  && mkdir -p ./redis-cluster/${port}/data; \

done

准备 compose 文件

    command:

      ["redis-server", "/etc/redis/redis.conf"]

networks:

  test_net:

    external: true

配置相对比较简单，需要注意下docker网络，提前创建好(docker network ls 可以查看具体有哪些网络)

redis 集群正式搭建

docker-compose -f '填写上述的compose文件名' up -d

进入启动的端口为7001的容器

docker exec -it container_id bash

集群搭建指令(提前关闭防火墙 iptables -F，也有别的指令，自行百度即可)：

redis-cli -p 7001 -a redispwd --cluster create 宿主机ip:7001 宿主机ip:7002 宿主机ip:7003 宿主机ip:7004 宿主机ip:7005 宿主机ip:7006 --cluster-replicas 1

等待集群自行搭建完成即可。

需要说明一下：此处搭建的为伪集群，即同一宿主机，不同端口。
