Redis 命令行界面

redis-cli 是 Redis 命令行界面程序,允许向 Redis 发送命令并直接从终端读取服务器发送的回复。基本命令行用法如下:

访问 redis:

$ redis-cli
127.0.0.1:6379>

通过身份验证访问 redis:

$ redis-cli -a myPassword
127.0.0.1:6379>

选择数据库并显示数据库大小(默认数据库编号为 0):

127.0.0.1:6379> dbsize
(integer) 2
127.0.0.1:6379> select 1
OK
127.0.0.1:6379[1]> dbsize
(integer) 20

获取有关服务器的信息和统计信息:
