- 去掉注释，把 `foobared` 改为你想要设置的密码，比如我打算设置为：123456，所以我改为：`requirepass 123456`

- 有了密码之后，进入客户端，就得这样访问：`redis-cli -h 127.0.0.1 -p 6379 -a 123456 `

- 如果用 IP 进入客户端，但是报：`Could not connect to Redis at 192.168.1.121:6379: Connection refused`

- 原因：Redis 默认只允许本机访问，可是有时候我们也需要 Redis 被远程访问。

- 修改 Redis 配置文件：`vim /etc/redis.conf`
