上面是redis服务器的信息。
无以“ X”'XTRIM','XADD','XGROUP'开头的命令不起作用。
[root@localhost lib]# redis-cli
127.0.0.1:6379> XTRIM TXNLOG MAXLEN 0
(error) ERR unknown command 'XTRIM'
127.0.0.1:6379> XGROUP CREATE TXNLOG test 0 MKSTREAM
(error) ERR unknown command 'XGROUP'

您应该升级到Redis 5.x
要首先执行此操作,请转到/tmp
目录:
$ cd /tmp
然后按来源下载和make
重做:
$ wget http://download.redis.io/releases/redis-5.0.5.tar.gz
$ tar xzf redis-5.0.5.tar.gz
$ cd redis-5.0.5
$ make
然后运行redis-server:
$ src/redis-server
