问题:客户端无法登录Redis服务器报错，解除保护模式解决方案1、修改redis服务器的配置文件vi redis.conf 注释以下绑定的主机地址# bind 127.0.0.1 2、修改redis服务器的参数配置 修改redis的守护进程为no ，不启用127.0.0.1:6379> config set daemonize "no"OK 修改redis的保护模式为no，不启用127.0.0.1:6379> config set protected-mode "no"注意:修改redis服务器的参数配置，只能通过redis-cli客户端修改(直接修改redis.conf没有效果)，如果redis服务器重启了，那么修改将会失效
