一个tomcat同时部署多个项目

一个tomcat同时部署多个项目

1. 注意事项：

1. 每一个service的端口号不能产生冲突

2. service的name属性的值可以重复 name="Catalina"

3. 每一个webapps下面需要有doc、manage两个文件夹，可以从已有的webapps下面复制

2. 默认的目录结构

只包含一个webapps文件夹，webapps下面包含docs、manager、root三个文件夹，log文件夹保存应用启动的控制台信息。

3. 复制webapps文件夹

先复制webapps文件夹，然后复制docs、manager文件夹

6. server.xml配置信息

一个tomcat同时部署多个项目-LMLPHP

7.Context配置

在toncat5.5版本之后，不推荐在server.xml中进行配置，而是在/conf/context.xml中进行独立的配置。因为 server.xml 是不可动态重加载的资源，服务器一旦启动了以后，要修改这个文件，就得重启服务器才能重新加载。而 context.xml 文件则不然， tomcat 服务器会定时去扫描这个文件。一旦发现文件被修改（时间戳改变了），就会自动重新加载这个文件，而不需要重启服务器 。

一个项目可以通过多个地址进入，如下：http://localhost:8080/或者http://localhost:8080/webroot或者http://localhost:8080/
