原因及解决方案

redis采用默认的linux服务器安装方式,默认是没有密码的,而我的springboot配置中,设置了密码

这里需要注意的是,如果没有密码,一定要将password的属性删除掉,密码为空也不行,我就是没有设置密码结果报了错,将password注释掉或者直接删除掉,再次启动,问题消失。

redis:
    host: 127.0.0.1  # redis服务器地址
    port: 6379 # redis服务器端口号
    # password: # redis密码

如果要使用密码,编辑服务器的redis.conf文件,找到 # requirepass foobared (大概在500行),去掉前面的注释,将默认密码foobared改为你自己的密码,保存,重启redis
