獲得Redis的狀態通過紅寶石

我想檢索使用Ruby腳本Redis的狀態，我想下面的命令：獲得Redis的狀態通過紅寶石

redis_status_command, stdeerr, status = Open3.capture3(`redis-cli -h 127.0.0.1 -p 6379 info|grep status`)

redis_status_command, stdeerr, status = Open3.capture3(`systemctl status redis`)

然後，當我嘗試打印變量redis_status_command它返回一個空格，但我知道Open3.capture3部分內的命令在命令行中工作。我如何使用Ruby檢索Redis狀態？謝謝

是否redis- rb gem包含你在找什麼？ - https://github.com/redis/redis-rb – arjabbar

隨着「redis的」寶石，你可以得到所有的信息屬性如下：

require 'redis' 
client = Redis.new(
    url: "redis://your-host.your-domain.com", 
    port: 6379 
) 
client.info

的輸出將是信息的哈希值：
