tomcat的配置文件server.conf中的元素的理解
tomcat作为一个servlet服务器本身的配置文件是tomcat_home/conf/server.conf,这个配置文件中有很多元素,这些元素各是什么意思,需要搞清楚,这里记录一下目前清楚的几个元素的含义。
tomcat本身是由一系列可配置的组件组成的,配置文件中的每一个元素都代表一个tomcat的组件。
1、Server元素
=============
Server元素代表servlet容器本身。
A Server element represents the entire Catalina servlet container.Therefore,
it must be the single outermost element in theconf/server.xml
configuration file.
Its attributes represent the characteristics of the servlet container as a whole.
2、Service
==========
Service元素代表了connector和engine的组合。
A Service element represents the combination of one or more Connector components
that share a single Engine component for processing incoming requests. One or more Service elements may be nested inside a Server element.
3、Engine元素
===============
Engine元素代表了一个Service组件的整个请求处理机构。
The Engine element represents the entire request processing machinery associated with a particular Catalina Service.
It receives and processes all requests from one or more Connectors,
and returns the completed response to the Connector for ultimate transmission back to the client. Exactly one Engine element MUST be nested inside a Service element,
following all of the corresponding Connector elements associated with this Service.
4、service中的两种connector
========================
在service元素中有两个connector元素,这两个connector元素的protocol属性的值是不一样的,一个是HTTP/1.1,另一个是AJP/1.3。
<Connector connectionTimeout="20000" port="8080" protocol="HTTP/1.1" redirectPort="8443"/> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>
它们两者的区别如下:
Tomcat中HTTP与AJP的区别:
Tomcat服务器通过Connector连接器组件与客户程序建立连接,Connector组件负责接收客户的请求,以及把Tomcat服务器的响应结果发送给客户。默认情况下,Tomcat在server.xml中配置了两种连接器:
第二个连接器监听8009端口,负责和其他的HTTP服务器建立连接。在把Tomcat与其他HTTP服务器集成时,就需要用到这个连接器。
5、未完待续
