Redis Ping Command

Redis Connections

The Redis Ping command sends a PING to the Redis server using the client. If the server is running normally, it will return a PONG.

It is usually used to test whether the connection with the server is still valid, or to measure the delay value.

Syntax

The basic syntax of the Redis Ping command is as follows:

redis　127.0.0.1:6379> PING

Available Version

>= 1.0.0

Return Value

If the connection is normal, it will return a PONG, otherwise it will return a connection error.
