docker-compose启动redis多机集群的实现

第一步

环境配置：

第二步

部署：

redis-node-1

yml

version: '2.2'

services:

redis-node-1:

image: bitnami/redis-cluster:7.0

restart: always

container_name: redis-node-1

network_mode: "host"

volumes:

- ./redis-cluster_data-1:/bitnami/redis/data

environment:

- 'REDIS_PASSWORD=liubei@161'

- 'REDIS_NODES=10.10.239.31 10.10.239.32 10.10.239.33 10.10.239.34 10.10.239.35 10.10.239.36'

持久化存储

如果我们不是root用户，自动创建挂载文件权限容器中执行初始化的过程一般会有问题。这里以容器中执行初始化的用户对应宿主机ID是1001的用户为例，他提前给了权限。如果你不是这个用户，可以先给777权限。等容器启动后看初始化后的文件主人是谁，就把该目录的主人改成谁，后面改回755或750权限就可以了。

[root@liubei-01 redis-cluster]# mkdir ./redis-cluster_data-1

[root@liubei-01 redis-cluster]# chown 1001 ./redis-cluster_data-1

启动

[root@liubei-01 redis-cluster]# docker-compose up -d

查看结果

[root@liubei-01 redis-cluster]# docker-compose ps

redis-node-2

version: '2.2'

services:

restart: always

container_name: redis-node-2

volumes:

跟上边一样，我在重复一遍。如果我们不是root用户，自动创建挂载文件权限容器中执行初始化的过程一般会有问题。这里以容器中执行初始化的用户对应宿主机ID是1001的用户为例，他提前给了权限。如果你不是这个用户，可以先给777权限。等容器启动后看初始化后的文件主人是谁，就把该目录的主人改成谁，后面改回755或750权限就可以了。

数据初始化：

redis-cli -h 10.10.239.31 -a liubei@161 --cluster create 10.10.239.31:6379 10.10.239.32:6379 10.10.239.33:6379 10.10.239.34:6379 10.10.239.35:6379 10.10.239.36:6379 --cluster-replicas 1
