redis集群密码配置 redis集群常用命令

Redis常用指令

1. 启动Redis服务
   ./redis-server /配置文件所在目录/配置文件.conf
2. 登录Redis客户端，认证密码
   ./redis-cli -c -h 服务端所在IP -p Port -a 'password' 或者

[user@主机名 bin]$./redis-cli -c -h 服务端所在IP -p Port 
IP:端口>auth 密码;
OK

3. 查看集群状态

[user@主机名 bin]$ ./redis-cli -c -h IP -p 6379 -a 'password'
ip:port>cluster info
cluster_state:ok
cluster_slots_assigned:16384
cluster_slots_ok:16384
cluster_slots_pfail:0
cluster_slots_fail:0
cluster_known_nodes:6
cluster_size:3
cluster_current_epoch:6
cluster_my_epoch:1
cluster_stats_messages_sent:14078059
cluster_stats_messages_received:14077537

4. 清除缓存

IP:port> dbsize
(integer) 370
IP:port> flushdb
OK
IP:port> dbsize
(integer) 0
IP:port> exit

5. 关键字删除缓存

./redis-cli -h IP -p 6379 -a 'password' keys "ORDER*" >123.txt
cat 123.txt |xargs -t -n1 ./redis-cli -h IP -p 6379 -a 'password' -c del

./redis-cli -h IP -p 6379 -a 'password' keys "ASET_*" >123.txt
cat 123.txt |xargs -t -n1 ./redis-cli -h IP -p 6379 -a 'password' -c del
