工作中项目一直放在测试环境中测试，但最近在正式环境中，有一次与同事联调的过程中，Tomcat 服务器出现异常，百思不得其解，之前一直正常的 Tomcat 出现异常，服务器窗口不间断输出 **org.apache.coyote.ajp.AjpMessage.processHeader Invalid message received with signature 5635**，但我并没有对服务器配置进行修改过，what？

如下为 Tomcat 服务器的报错信息

自 **Server startup in 10852 ms** 启动之后，持续不间断的输出严重的报错信息，通过浏览器访问 Tomcat/conf/Server.xml 配置的端口也无法访问，通过报错信息追踪，问题产生于这一配置

<table> 
 <tbody> 
  <tr> 
   <td> <pre><code>1
</code></pre> </td> 
   <td> <pre><code>&lt;Connector port="8096" protocol="AJP/1.3" redirectPort="8443"/&gt;
</code></pre> </td> 
  </tr> 
 </tbody> 
</table>

而在 Stack Overflow 中，对于 AjpMessage.processHeader 问题的记录并不多， 对于配置的修改则为将 AJP/1.3 替换为 HTTP/1.1，但这个修改对 5635 报错并没有起作用，反而会引起其他的报错信息。

对此，修改了如下配置便解决了一直输出端口严重错误的问题：

<table> 
 <tbody> 
  <tr> 
   <td> <pre><code>1
</code></pre> </td> 
   <td> <pre><code>&lt;Connector port="8096" protocol="AJP/1.3" address="127.0.0.1" redirectPort="8443"/&gt;
</code></pre> </td> 
  </tr> 
 </tbody> 
</table>

添加 address 属性，将地址指向本地服务器，关于 address 属性，[官方文档][Link 1] 也有具体说明，在默认的情况下，此端口将用于与服务器关联的所有IP地址，指定本地则免去暴露的危险，这个情况早在 Tomcat7 时就有出现，而此处使用 Tomcat8 也在启动时进行检测，避免该情况发生。

--------------------

鉴于以上配置和今天遇到的一下log打印的错误，错误号各有不同

运行tomcat最后在窗口打印出   Invalid message received with signature 18245这个错误，只是写了一个简单的demo，最后百度了一通，说是`Tomcat`的`Ajp`端口`8009，外网访问的原因，`如果没有指定`IP`地址的话，默认是绑定任意地址，这样就导致外网也可以访问这个端口。因此出于安全考虑，我们需要增加这个`address`的设置，并且绑定到`127.0.0.1，结果如下：`<Connector port="8009" protocol="AJP/1.3" address="127.0.0.1" redirectPort="8443" />，修改的目录是tomcat下的conf/server.xml文件，里面找一下port=‘8009’的那一行，**添加address="127.0.0.1"。**
