tomcat 远程部署

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

主要是增加一个 具有系统管理权限的用户,比如增加一个用户名和密码都是admin的用户,只需要在在最后一行增加

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>     
  <role rolename="admin"/>   
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
  <user username="admin" password="admin"   roles="admin,manager"/>

然后,我们可以进入http://localhost:8080/manager/status 来查看服务器的各种状态.
也可以通过url来直接对应用进行监控
命令格式 代码

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

部 署一个应用

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 出已经部署的应用

http://localhost:8080/manager/list

重 新加载一个应用
比如你更新了class或者lib的话，需要重新加载系统

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

查 看jvm和系统信息

http://localhost:8080/manager/serverinfo

查 看可用的安全角色

http://localhost:8080/manager/roles

查 看某个应用默认的session超时时间和当前活跃的session数

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

启 动一个应用
比如有时候重新启动数据库后可能需要重新启动应用

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

关 闭一个应用
关闭后，任何发往该应用的请求都将转向404错误的页面

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

undeploy
慎 用，将删除应用的目录及其war文件
ant脚本，更多的详见tomcat5.5的文档
