配置TOMCAT 修改默認ROOT路徑

最合適的）

最直接的辦法是，刪掉tomcat下原有Root文件夾，將自己的項目更名為Root。

我在$tomcat/webapps/下建了個myjsp目錄作為我網站的默認目錄，在myjsp中有一個a.jsp文件，該文件要作為我網站的默認主頁。

修改配置文件：

首先，修改$tomcat/conf/server.xml文件。
在server.xml文件中，有一段如下：
……
<engine name="Catalina" defaultHost="localhost">
<host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
……
<host>
</engine>
……
在<host></host>標簽之間添加上：

<Context path="" docBase="myjsp" debug="0" reloadable="true" />

path是說明虛擬目錄的名字，如果你要只輸入ip地址就顯示主頁，則該鍵值留為空；

docBase是虛擬目錄的路徑，它默認的是$tomcat/webapps/ROOT目錄，現在我在webapps目錄下建了一個myjsp目錄，讓該目錄作為我的默認目錄。

debug和reloadable一般都分別設置成0和true。

然后，修改$tomcat/conf/web.xml文件。
在web.xml文件中，有一段如下：
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
在<welcome-file-list>與<welcome-file>index.html</welcome-file>之間添加上：

<welcome-file>a.jsp</welcome-file>

更改端口
<Connector port="8080" maxThreads="150" minSpareThreads="25" maxSpareThreads="75" enableLookups="false" redirectPort="8443" acceptCount="100" debug="0" connectionTimeout="20000" disableUploadTimeout="true" /> 


將port "8080"改成你的端口

保存上述兩個文件后重啟tomcat，在瀏覽器地址欄內輸入" http://localhost:8080/"，顯示a.jsp頁面的內容。

【轉】 如何修改TOMCAT的默認主頁為你自己項目的主頁

啟動tomcat之后，在貓頁上有這么一段話:

As you may have guessed by now, this is the default Tomcat home page. It can be found on the local filesystem at: 
$CATALINA_HOME/webapps/ROOT/index.html

這就說明，無論你怎么折騰你自己的web.xml文件，對不起，tomcat只認它自己的web.xml定義的welcome頁面。

而<welcome-file-list>標簽上的這段注釋:

<!-- If you define welcome files in your own application's web.xml -->
<!-- deployment descriptor, that list *replaces* the list configured -->
<!-- here, so be sure that you include any of the default values that -->
<!-- you wish to include.

-->

修改過程

1.不要碰conf目錄下的那個web.xml文件，讓它老死在那里吧。

2.把原來的ROOT目錄清空，里面什么都不要留。刪掉或者改名隨便你怎么弄都成。只要清空就好。

3.發布你自己的項目到ROOT目錄下，用war包發布或者用直接拷貝的都一個效果。保證index.html/index.htm/index.jsp其中一個存在於ROOT目錄下。

4.刪除%CATALINA%/work目錄下的一切。我就是沒有清理這個目錄，導致 http://localhost:8080永遠都是那只貓~~~~郁悶

5.通知服務商重啟tomcat。

（二）

這里把用指定項目的主頁替換tomcat主頁的方法記錄一下:

1、 更改tomcat端口為80

在tomcat目錄conf下找到server.xml打開，找到

<Connector port="80" protocol="HTTP/1.1"

connectionTimeout="0"

redirectPort="8443" URIEncoding="gb2312"/>

port改為80.

如端口80被占用，解決方法：解決：在win的cmd命令窗口輸入netstat -abn ->c:/port80.txt 然后到c盤port80.txt文件中找到占用80端口的程序pid，記下pid。打開任務管理器，點擊“查看”/選擇列，勾選“PID(進程標識符)”，然后單擊“進程”標簽，找到80端口對應的pid，就可以看到是那個程序占用的了，更改這個程序的port，再重啟這個程序，使更改生效。

2、 設置默認訪問主頁為指定項目。

在server.xml中找到

<Host name="localhost" appBase="webapps"

unpackWARs="true" autoDeploy="true"

xmlValidation="false" xmlNamespaceAware="false">

</Host>

在標簽中間插入：

<Context path="" docBase="xbwl" debug="0" reloadable="true"/>

docBase="xbwl" xbwl即為指定的項目。

完整如下：

<Host name="localhost" appBase="webapps"

unpackWARs="true" autoDeploy="true"

xmlValidation="false" xmlNamespaceAware="false">

<Context path="" docBase="xbwl" debug="0" reloadable="true"/>

</Host>

 

（三）

可以通過以下操作實現更改tomcat的默認主頁所在的目錄。
替換並保存一下內容為conf文件夾下的server.xml
<?xml version='1.0' encoding='utf-8'?>

方法一：（適合對服務器中單個站點的設置）
（d:\demo\為站點根目錄）
在Tomcat中，默認主頁為：index.html,index.htm,index.jsp
如果需要使用其他頁面作為默認主頁，需要配置WEB-INF文件夾下的web.xml文件:
如上例中：
在D:\demo\WEB-INF\文件夾中建立文件web.xml：
內容如下：

<?xml version=”1.0″ encoding=”UTF-8″?>
<web-app version=”2.4″
xmlns=”http://java.sun.com/xml/ns/j2ee”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”
xsi:schemaLocation=”http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd“>
<welcome-file-list>
<welcome-file>hello.jsp</welcome-file>
</welcome-file-list>
</web-app>

方法二：（以下設置將應用於該服務器下所有的站點）推薦使用
打開文件conf/web.xml，找到這段代碼：

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

在中間加入你想要的文件名即可。
如：我想讓hello.jsp成為默認首頁，我將上面那段代碼改成：

<welcome-file-list>
<welcome-file>hello.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
