解决问题：

关闭Redis
打开redis-cli, 输入

shutdown

看到

退出成功

修改配置文件
找到redis的配置文件，一般在/usr/local/redis/目录下，使用vim打开配置文件

sudo vim redis.conf #根据文件名自行输入
1

然后输入密码

搜索需要修改的配置，“ / ”为搜索

/protected-mode
1

输入i 然后将protected-mode yes 修改为 protected-mode no

同理修改requirepass *******这里“ * ”作为密码

然后注释掉bind

保存配置文件
点击ESC键后输入

：wq!
1

关闭虚拟机的防火墙

systemctl stop firewalld.service
1

重启Redis
使用指定配置文件启动redis

./bin/redis-server redis.conf

连接远程redis

redis-cli -h 你的Redis所在主机的ip地址 -p 端口 -a 密码
