$ redis-cli -h ec2-75-101-204-XXX.compute-1.amazonaws.com
Could not connect to Redis at ec2-75-101-204-XXX.compute-1.amazonaws.com:6379: Operation timed out
这就是我从我的主机得到的。我将该机器上的安全组设置为对端口 6379 开放。
当我在 redis 服务器上运行 netstat 时,我看到它正在监听:
$ netstat -nlp
(No info could be read for "-p": geteuid()=1000 but you should be root.)

样子:
daemonize yes
pidfile /var/run/redis.pid
port 6379

那么为什么我会从另一台机器超时呢?
