redis下載

最好下載一份新的redis.conf

我redis7.0.0 報錯，后重新下載了一份 redis.conf ，解決

*** FATAL CONFIG FILE ERROR (Redis 7.0.0) *** replicaof directive not allowed in cluster mode***致命配置文件錯誤（Redis 7.0.0）*** 集群模式下不允許復(fù)制指令

配置文件

一個配置文件，然后修改出6個配置文件

include /Users/software/redis-7.0colony/conf/redis.conf# 端口號 port 7001# redis進程文件 pidfile /Users/software/redis-7.0colony/conf/redis7001.pid# rdb文件名 dbfilename redis7001.rdb# aof文件名 appendfilename "appendonly7001.aof"# 集群 cluster-enabled yes# 生成node文件 cluster-config-file nodes7001.conf# 后臺啟動 daemonize yes#aof、rdb文件存儲目錄 dir /Users/software/redis-7.0colony/data/bind 0.0.0.0# 設(shè)置密碼 requirepass 123456masterauth 123456

創(chuàng)建配置文件

redis7001.conf

redis7002.conf

redis7003.conf

redis7004.conf

redis7005.conf

redis7006.conf

只需要修改路徑，7001的修改和文件端口保持一致

啟動

redis-server ../conf/redis7001.conf redis-server ../conf/redis7002.conf redis-server ../conf/redis7003.conf redis-server ../conf/redis7004.conf redis-server ../conf/redis7005.conf redis-server ../conf/redis7006.conf

檢查是否啟動成功

redis-cli -p 7001 auth 123456

最好將data目錄下的數(shù)據(jù)刪除

# -a 設(shè)置登錄密碼，如不填加，則報錯 # [ERR] Node 192.168.0.104:6379 NOAUTH Authentication required. # –replicas 1 采用最簡單的方式配置集群，一臺主機，一臺從機，正好三組redis-cli --cluster create --cluster-replicas 1 \ 127.0.0.1:7001 \ 127.0.0.1:7002 \ 127.0.0.1:7003 \ 127.0.0.1:7004 \ 127.0.0.1:7005 \ 127.0.0.1:7006 -a 123456

控制臺輸出 輸入 yes
