修改Redis端口和密码
vim  /etc/redis/6379.conf

#后台运行
daemonize yes
#端口
port 6379

#密码
requirepass password


redis-cli
  -h <主机ip>，默认是127.0.0.1
  -p <端口>，默认是6379
  -a <密码>，如果redis加锁，需要传递密码

Redis 连接

redis-cli -h 127.0.0.1 -p 6379 -a password


开启远程访问，在redis3.2之后，redis增加了protected-mode，在这个模式下，即使注释掉了bind 127.0.0.1，

#bind 127.0.0.1
