怎么查看redis当前连接

在Redis中，我们可以通过`info clients`命令来查看当前的连接信息，这个命令会返回一个表格，包含了所有的客户端连接信息，包括IP地址、端口号、已读字节数、已写字节数等。

你需要打开Redis的服务器端，然后在命令行中输入`info clients`命令，如果你的Redis服务器设置了密码，你还需要先使用`AUTH`命令进行身份验证。

127.0.0.1:6379> AUTH your_password
OK
127.0.0.1:6379> info clients

返回的结果可能如下：

# Clients
connected_clients:4
client_longest_output_list:0
client_biggest_input_buf:0
blocked_clients:0

`connected_clients:4`表示当前有4个客户端连接到Redis服务器，`client_longest_output_list:0`表示最长输出列表的长度为0，`client_biggest_input_buf:0`表示最大输入缓冲区的大小为0，`blocked_clients:0`表示没有阻塞的客户端。

如果你想查看特定客户端的详细信息，你可以使用`CLIENT list`命令，后面跟上客户端的ID。

127.0.0.1:6379> CLIENT list id

返回的结果可能会包含客户端的详细信息，如IP地址、端口号、已读字节数、已写字节数等。

以下是四个与本文相关的问题及解答：

问题1：如何查看Redis服务器的最大连接数？

答：你可以通过`CONFIG GET maxclients`命令来查看Redis服务器的最大连接数。

127.0.0.1:6379> CONFIG GET maxclients
1) "maxclients"
2) "16384"

这表示Redis服务器的最大连接数为16384。

问题2：如何查看Redis服务器的运行时间？

答：你可以通过`INFO GET timestamp`命令来查看Redis服务器的运行时间。

127.0.0.1:6379> INFO GET timestamp
# Redis server started at Thu, 05 May 2022 18:59:44 +0800

这表示Redis服务器开始运行的时间是2022年5月5日18点59分44秒。

问题3：如何查看Redis服务器的CPU使用率？

答：你可以通过`INFO CPU`命令来查看Redis服务器的CPU使用率。

“`bash

127.0.0.1:6379> INFO CPU

This is an aggregated report that includes the total number of queries served and the total amount of time spent serving them (seconds), as well as the current load (currently 0.00/sec).
