我正在尝试在亚马逊云上创建一个简单的网络服务器。但是每次我在断开连接后安装 apache 时,我都无法再通过 SSH 连接回服务器。
djc@ubuntu:~/Desktop$ ssh -v -i lobbymonitor2.pem ec2-user@ec2-23-20-4-255.compute-1.amazonaws.com
OpenSSH_6.1p1 Debian-4, OpenSSL 1.0.1c 10 May 2012
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 19: Applying options for *

debug1: connect to address 23.20.4.255 port 22: Connection refused
ssh: connect to host ec2-23-20-4-255.compute-1.amazonaws.com port 22: Connection refused
Apache 中是否有我需要更改但我缺少的设置?
