一個tomcat同時部署多個項目

1. 注意事項：

1. 每一個service的端口號不能產生沖突

2. service的name屬性的值可以重復 name="Catalina"

3. 每一個webapps下面需要有doc、manage兩個文件夾，可以從已有的webapps下面復制

2. 默認的目錄結構

只包含一個webapps文件夾，webapps下面包含docs、manager、root三個文件夾，log文件夾保存應用啟動的控制台信息。

3. 復制webapps文件夾

先復制webapps文件夾，然后復制docs、manager文件夾

 

4. 配置conf\server.xml

6. server.xml配置信息

 

7.Context配置

在toncat5.5版本之后，不推薦在server.xml中進行配置，而是在/conf/context.xml中進行獨立的配置。因為 server.xml 是不可動態重加載的資源，服務器一旦啟動了以后，要修改這個文件，就得重啟服務器才能重新加載。而 context.xml 文件則不然， tomcat 服務器會定時去掃描這個文件。一旦發現文件被修改（時間戳改變了），就會自動重新加載這個文件，而不需要重啟服務器 。

一個項目可以通過多個地址進入，如下：http://localhost:8080/或者http://localhost:8080/webroot或者http://localhost:8080/

webroot1
