如何獲取Tomcat的管理員用戶和密碼以訪問Servlet列表

Question

當我訪問localhost tomcat並單擊“ ManagerApp”時，這就是我得到的

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.

那么我該如何解決呢？

Answer 1

加

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

到<tomcat-users>標記內的tomcat directory/conf/tomcat-users.xml然后重新啟動tomcat服務，並使用此憑據登錄到localhost:8080或IP:8080 。

您可以從tomcat-users.xml文件中更改用戶名和密碼。

當您訪問localhost:8080並單擊host-manager或其他頁面時，它將要求輸入用戶名和密碼，然后添加上述credentials 。

因此，您的上述錯誤將不會發生。

您必須在tomcat的安裝時提供此憑據。

還是給我發問題。
