Redis binds multiple listening IPs or unbind

If a system port 6379 is bound to listen on ip127.0.0.1, the port will only deny connections to non-listening IP hosts through connection requests from this IP.

Telnet 10.10.86.211 9000
Trying 10.10.86.211 ...
Telnet:connect to address 10.10.86.211:connection refused

Another reason: firewall interception. (only need to release the corresponding host IP in the firewall of the Telnet server, the port can be)

If the port is bound to listen to IP, which causes connection refused, the analysis resolves:

or modify the configuration document (e.g. REDIS,/ETC/REDIS.CNF)

Vim/etc/redis.cnf

Bind 127.0.0.1 before adding #, the 6379 port will not only listen on the local IP

$ telnet 10.10.86.211 6379
