启动方式一（不推荐）：一个一个启动
启动第一个redis节点
docker run -p 6371:6379 -p 16371:16379 --name redis-1 \-v /var/redisNode/node-1/data:/data \-v /var/redisNode/node-1/conf/redis.conf:/etc/redis/redis.conf \-d --net redis --ip 172.38.0.11 redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf如上，类似的，递增ip、port和name，启动其它五个redis节点，太麻烦了，可以通过编写脚本来一次启动6个服务
启动方式二（推荐）：编写启动脚本，6个全部启动
创建start_redis_script.sh文件touch start_redis_script.sh编写脚本内容vim start_redis_script.sh，写入下面的内容
for port in $(seq 1 6); \do \echo ${port}docker run -p 637${port}:6379 -p 1637${port}:16379 --name redis-${port} \-v /var/redisNode/node-${port}/data:/data \-v /var/redisNode/node-${port}/conf/redis.conf:/etc/redis/redis.conf \-d --net redis --ip 172.38.0.1${port} redis:5.0.9-alpine3.11 redis-server /etc/redis/redis.conf; \done赋予start_redis_script.sh文件可执行权限[root@--- ~]# chmod o+x start_redis_script.sh执行脚本，启动redis容器服务./start_redis_script.sh

进入redis-1容器docker exec -it redis-1 /bin/sh创建集群主节点
  • Redis Cluster最低要求是3个主节点
  • --cluster-replicas 参数为数字，1表示每个主节点需要1个从节点 。
