java - 如何获取 Tomcat 的管理员用户和密码以访问 Servlets 列表

Question

当我访问本地主机 tomcat 并单击“ManagerApp”时，这就是我得到的结果

403 Access Denied
You are not authorized to view this page.

If you have already configured the Manager application to allow access and you have used your browsers back button, used a saved book-mark or similar then you may have triggered the cross-site request forgery (CSRF) protection that has been enabled for the HTML interface of the Manager application. You will need to reset this protection by returning to the main Manager page. Once you return to this page, you will be able to continue using the Manager appliction's HTML interface normally. If you continue to see this access denied message, check that you have the necessary permissions to access this application.

If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp.

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
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
The HTML interface is protected against CSRF but the text and JMX interfaces are not. To maintain the CSRF protection:

Users with the manager-gui role should not be granted either the manager-script or manager-jmx roles.
If the text or jmx interfaces are accessed through a browser (e.g. for testing since these interfaces are intended for tools not humans) then the browser must be closed afterwards to terminate the session.
For more information - please see the Manager App HOW-TO.

那么我该如何解决这个问题？

Answer 1

添加

<user name="admin" password="admin" roles="admin-gui,manager-gui" />

到tomcat directory/conf/tomcat-users.xml里面<tomcat-users>标记并重新启动 tomcat 服务并使用此凭据登录到 localhost:8080或 IP:8080 .

您可以从 tomcat-users.xml 更改用户名和密码文件。

当您访问localhost:8080时当点击 host-manager或其他页面然后它会询问用户名和密码，然后在 credentials 上方添加.

那么就不会出现你上面的错误了。

您必须在安装 tomcat 时提供此凭据。

仍然有问题发帖给我。
