应用场景：

系统在用户的使用过程中，多少有些错误信息，异常报错等，这些不能给用户造成困惑

所以警告或错误统一在日志中记录下来，方便维护人员对系统进行优化和修改。

但是这些日志，可能在不同的服务器上，怎么统一管理进行监控呢？那么就用到了Xshell

Xshell ；远程连接服务器，强大的安全终端模拟软件。今天就只聊查看服务器上动态更新的错误警告日志

为啥用Xshell？

其实我目前也就用了这一个：据说它可以保证数据在传输过程中的安全，这就涉及到了网络协议：Xshell支持Telnet,ssh 协议

安全——两个协议：

【前言】

我们常见的是http （hypertext transfer protocol，超文本传输协议）,是在客户端和web服务器端常见的一种通过加头加尾，到去头去尾的一个过程，建立连接-发送请求-响应请求-关闭连接，以这样的过程让双方可以进行很好的通信。但是这样简单的传输，如果有中间想要窃取信息的人，就可以直接获取到数据。

【Telnet（teletype network）】是远程的传输协议 Telnet协议 

怎么解释远程：我们应该都有通过别人的电脑，远程登录自己的电脑，可以在别人的电脑上操作自己的电脑的经历，那么这个过程，就要是你的和对方的电脑都有Telnet协议，才可以建立连接。

远程登录的过程中，知道远程主机IP地址-知道登录口令

实际应用：这就是我们通过自己电脑的Xshell,连接远程服务器的时候，要输入IP的步骤

但是Telnet较为简单，单他在传输信息的过程中，都是用明文传送的，包括输入的登录口令，有一定的安全隐患，所以在Telnet基础上，引入的下面的协议

【SSH(Secure shell)】在本地主机可远程服务器间进行加密传输数据

怎么加密：加密方式有两种，对称加密，非对称加密

目前了解的对称加密：加密方，和解密方用同一个东西进行加密，解密（让我想到电视剧中地下党在传递信息的时候，用一种药水在纸上写字，但是别人看不出来，只有用同一种药水浸泡后才可以看到，也许是一样的道理）

非对称加密：加密方，和解密方用不同一个东西进行加密，解密（还是上面的例子；用药水写字的纸要用火烤才可以显示出来）

具体怎么做的呢：


SSH的工作机制大体是：本地客户端发送一个连接请求到远程的服务端，服务端检查申请的包和IP地址再发送密钥给SSH客户端，本地再将密钥发回给服务端，到此为止，连接建立。

启动SSH服务器后，sshd进程运行并在默认的22端口进行监听。安全验证方式：基于口令的安全验证（账号密码），也有可能受到中间人攻击


实际应用:上面提到的基于口令的验证方式，大概就是我们在使用Xshell在输入了IP建立了远程连接之后，需要输入如下内容：



接下来就要输入密码了，但在输入密码的时候我们有连个选择：1、密码  2、公钥



这就是另一种安全验证方式：


基于密钥的安全验证，就是提供一对密钥，把公钥放在需要访问的服务器上，如果连接到SSH服务器上，客户端就会向服务器发出请求，请求用密钥进行安全验证，服务器收到请求之后，先在改服务器的主目录下寻找公钥，然后把它和发送过来的公钥进行比较。如果两个密钥一致，服务器就用公钥加密“质询”并把它发送给客户端。客户端收到“质询”之后就可以用私钥解密再把它发给服务器端。基于这种方式，相对比较安全。


这个是用用户名，密码登录成功后的提示：上面是通过telnet建立连接后的内容，红框中是通过SSH建立口令验证方式登录成功后，提示连接时间from我的主机ip (没有用密钥尝试过，还不太清楚可以参考博客SSH协议详解)



 

一个页面用了两个el-form。form2用了校验，因此每一个form-item都写了prop，但是form1没有写。结果怎么提交都不对，把form1的prop都加上就解决啦。
