如何通过远程服务器/URL运行Redis客户端及查看Redis连接列表？

Hey there, let's walk through your questions step by step:

1. How to run a Redis client against a remote server? #

Connecting to a remote Redis instance with the official redis-cli tool is straightforward—here are your go-to options, depending on server authentication requirements:

• Basic connection (no password): Use the -h flag to specify the remote server's IP/hostname, and -p for the port (you can skip -p if using the default 6379 port).
  Example:

  redis-cli -h 10.0.0.5 -p 6379
  

• Connection with password authentication: Either pass the password directly with the -a flag, or connect first then authenticate with the AUTH command.
  Example with -a:

  redis-cli -h 10.0.0.5 -p 6379 -a mySecurePassword123
  

  Example with post-connection auth:

  redis-cli -h 10.0.0.5 -p 6379
  # Once connected, run:
  AUTH mySecurePassword123
  

2. How to run a Redis client via a remote URL, and how to get the list of connections in Redis cache? #

Connecting via a remote URL #

Redis supports URL-based connection strings with redis-cli, which is great for scripting or quick one-off connections. The URL format is:
redis://[:password@]host:port/database_number

• No password, default database (0):

  redis-cli redis://10.0.0.5:6379
  

• With password and specific database:

  redis-cli redis://:mySecurePassword123@10.0.0.5:6379/2
  

Retrieving active connections #

To get full details about all current client connections to your Redis server, use the INFO clients command. When you run this in the connected client, it returns a section with metrics like total connected clients, plus a detailed list of each connection's metadata (IP address, port, idle time, etc.).

Example output snippet:

Clients #

connected_clients:7
blocked_clients:0
client_list:id=4 addr=192.168.1.20:45678 fd=6 name= age=24 idle=5 flags=N db=0 sub=0 psub=0 multi=-1 qbuf=0 qbuf-free=32768 obl=0 oll=0 omem=0 events=r cmd=ping

For a more concise, line-by-line breakdown of every connection, use the CLIENT LIST command directly—each line represents a single client connection with all its associated details.
