私にはUbuntu 18.xでこの問題がありましたが、私の問題は、redis-serverが127.0.0.1で実行されていたが、自分のIPアドレスxxx.xx.xx.xxで実行する必要があることがわかりました
私は自分のUbuntuマシンに入り、次のことを行いました。
cd /etc/redis/
sudo vim redis.conf
その後、この部分を編集しました。
################################## NETWORK #####################################
# By default, if no "bind" configuration directive is specified, Redis listens
# for connections from all the network interfaces available on the server.
# It is possible to listen to just one or multiple selected interfaces using
# the "bind" configuration directive, followed by one or more IP addresses.
#
# Examples:
#
# bind 192.168.1.100 10.0.0.1
# bind 127.0.0.1 ::1
#
# ~~~ WARNING ~~~ If the computer running Redis is directly exposed to the
# internet, binding to all the interfaces is dangerous and will expose the
# instance to everybody on the internet. So by default we uncomment the
# following bind directive, that will force Redis to listen only into
# the IPv4 loopback interface address (this means Redis will be able to
# accept connections only from clients running into the same computer it
# is running).le to listen to just one or multiple selected interfaces using
#
# IF YOU ARE SURE YOU WANT YOUR INSTANCE TO LISTEN TO ALL THE INTERFACES
# JUST COMMENT THE FOLLOWING LINE.
# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
# bind 127.0.0.1 ::1 10.0.0.1
bind 127.0.0.1 ::1 # <<-------- change this to what your iP address is something like (bind 192.168.2.2)
それを保存して、redis-serverを再起動します。
sudo service redis-server restart
または単に実行する redis-server
