容器內(nèi)端口不能都是是6379，集群總線接口是端口號(hào)+10000
端口號(hào)與network_mode: "host"不能一起配置，出現(xiàn)下述問題“主機(jī)”網(wǎng)絡(luò)模式與端口綁定不兼容問題，具體看github,有對(duì)應(yīng)解釋。

ERROR: for cluster_redis_6379  "host" network_mode is

docker-compose up -d

進(jìn)入容器

 docker exec -it cluster_redis_6379 bash

遇到的問題

如果一直卡在Waiting for the cluster to join，那一般是端口問題，看看集群總線端口是否開啟，我在這遇到問題，修改了redis.conf中的端口，將容器中端口都是6379改成不同的,并且在docker-compose.yml的port中，加上各個(gè)節(jié)點(diǎn)的總線端口好了。

集群數(shù)據(jù)庫數(shù)量問題

Response received : -ERR SELECT is not allowed in cluster mode

在集群模式下這個(gè)配置是不起作用的，集群客戶端是不支持多數(shù)據(jù)庫db的，只有一個(gè)數(shù)據(jù)庫默認(rèn)是SELECT 0;

在某個(gè)控制臺(tái)里，比如6379,如果存放的key值對(duì)應(yīng)的槽位不在6379的槽位之中，是不能存放的文章來源地址http://www.zghlxwxcb.cn/news/detail-667969.html
