1：在tomcat conf/tomcat-users.xml 文件里 配置用户名和密码，以及访问方式
For example, to add the manager-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above.
<role rolename="manager-gui"/>
<user username="tomcat" password="s3cret" roles="manager-gui"/>
Note that for Tomcat 7 onwards, the roles required to use the manager application were changed from the single manager role to the following four roles. You will need to assign the role(s) required for the functionality you wish to access.
- manager-gui - allows access to the HTML GUI and the status pages //可以通过网页访问 ，rolename=manager-gui
- manager-script - allows access to the text interface and the status pages
- manager-jmx - allows access to the JMX proxy and the status pages
- manager-status - allows access to the status pages only
2：通过用户名和密码访问，可以通过html发布项目
