For redis related issues, first determine whether the password and the like in redis.conf need to turn off the protection mode (set to no) and comment out the bind xxx in conjunction with ps -efGrep redis whether the port exists in redis-server *: 6379 similar to this no problem redis -cli command operation is no problem (look down if you haven't solved it after excluding it)
Turn off the firewall / vim / etc / sysconfig / iptables add whitelist in windows cmd test
telnet host 6379
