tomcat5.5的管理功能非常強,只要你配置好了tomcat-user.xml.

主要是增加一個具有系統(tǒng)管理權(quán)限的用戶,比如增加一個用戶名和密碼都是suxiaoyong的用戶,只需要在在最后一行增加

代碼

<user username="suxiaoyong" password="suxiaoyong" roles="admin,manager"/>

其他的用戶都可以刪掉了

然后,我們可以進入http://localhost:8080/manager/status 來查看服務(wù)器的各種狀態(tài).

也可以通過url來直接對應(yīng)用進行監(jiān)控

命令格式

代碼

http://{ host }:{ port }/manager/{ command }?{ parameters }

部署一個應(yīng)用

代碼

http://localhost:8080/manager/deploy?path=/foo

http://localhost:8080/manager/deploy?path=/foo

http://localhost:8080/man......o&war=file:/path/to/foo

http://localhost:8080/manager/deploy?war=foo

http://localhost:8080/man......ath=/bartoo&war=bar.war

列出已經(jīng)部署的應(yīng)用

代碼

http://localhost:8080/manager/list

重新加載一個應(yīng)用

比如你更新了class或者lib的話，需要重新加載系統(tǒng)

代碼

http://localhost:8080/manager/reload?path=/examples

查看jvm和系統(tǒng)信息

代碼

http://localhost:8080/manager/serverinfo

查看可用的安全角色

代碼

http://localhost:8080/manager/roles

查看某個應(yīng)用默認的session超時時間和當(dāng)前活躍的session數(shù)

代碼

http://localhost:8080/manager/sessions?path=/examples

啟動一個應(yīng)用

比如有時候重新啟動數(shù)據(jù)庫后可能需要重新啟動應(yīng)用

代碼

http://localhost:8080/manager/start?path=/examples

關(guān)閉一個應(yīng)用

關(guān)閉后，任何發(fā)往該應(yīng)用的請求都將轉(zhuǎn)向404錯誤的頁面

代碼

http://localhost:8080/manager/stop?path=/examples

?
undeploy

慎用，將刪除應(yīng)用的目錄及其war文件

ant腳本，更多的詳見tomcat5.5的文檔

代碼
