整个暑假，我都不能使用 ssh 远程连接上我的 CentOS 7 主机，只能通过 TeamViewer 连接。尽管 TeamViewer 连接使用已经很好了，TeamViewer 需要直接使用图形化的传输，势必影响到连接的快慢。因此，还是需要解决使用 ssh 的问题。 几经周折，终于找到了问题所在。因此 CentOS 7 使用 firewalld 来管理网络安全问题，而原来是使用 iptables。因此，当从原来的 CentOS 6 迁移到 7 的时候，iptables 继续使用，而未开启 firewalld。最近一次升级，不知道怎么弄的，firewalld 自动开启，而造成 ssh 不能远程利用。Firewalld 默认情况下是开启 ssh 的，但是当我检查 22 端口时，这个端口却没有开启。因此，需要开启 22 端口，不再使用 iptables.
