Redis cannot connect remotely.

CentOS9 Installed on redis, And successfully started , Unable to connect on the host .

Mainly parameter setting Incorrect .

First, install by default redis after   Direct command start redis-server  It's not true . It will call the default parameters to start redis.

We need to use it. redis.conf File to start

redis-server /etc/redis/redis.conf

There are several reasons why you can't connect .

1. bind Parameters are not set correctly

redis bind The default parameter is 127.0.0.1 This way redis Bound to local and its The external device cannot be connected

We need to comment it out directly .

    # bind 127.0.0.1

then modify redis The protection mode of is no, Is not enabled

protected-mode no

For the sake of safety You need to set the password

requirepass root

then Can Remote access to

We try to connect on the client

Still unable to connect , Think about it Should be   CentOS9 Firewall does not 6379 Ports open .

[[email protected] redis]# firewall-cmd --query-port=6379/tcp
no

It really didn't open after inspection

Then we open the port .

[[email protected] redis]# firewall-cmd --add-port=6379/tcp
success
[[email protected] redis]# firewall-cmd --query-port=6379/tcp
yes

After opening the port, we are connecting with the client

 

Successful connection , solve the problem .
