我有3台WHM服务器，我想将一些文件从server1和server2传输到server3。
我在server1上备份了文件，在server2上备份了数据库，现在我需要使用SSH从server1和server2获取文件到server3。
我使用SSH登录到server3并使用wget命令从server1获取文件 - 工作正常。当我尝试使用wget从server2获取文件时，我收到“连接被拒绝”错误。
可能有什么问题？
编辑：我使用在线工具检查端口是否在server2打开，我发现端口22和80已关闭。这很奇怪，因为当我登录WHM并检查防火墙配置时，两个端口都列在TCP_IN，TCP_OUT，UDP_IN和UDP_OUT下。如何使用ssh或whm打开端口？
我也检查了server1并打开了端口，所以我想这就是为什么我无法从server2获取文件，因为端口22和80已关闭。
这是netstat -lan |的输出egrep LISTEN

编辑：我检查了server1和server2上的/ etc / ssh / sshd_config，一切都是一样的，但由于某种原因，server2拒绝连接。
答案 0 :(得分：0)
问题解决了。我使用在线工具检查已打开的端口，端口22和80已关闭，这就是连接被拒绝的原因。
谢谢大家的帮助。
