tomcat使用manager管理app時需要身份驗證問題

我們可以通過圖形用戶界面來管理tomcat，啟動tomcat，在地址欄中輸入：

Java代碼

1. http://localhost:8080

就可以看見tomcat的歡迎頁面，點擊左邊的tomcat manager 就會出現一個對話框，需要輸入用戶名和密碼，當忘記最開始安裝tomcat時的用戶名和密碼時，我們可以通過以下方傑來解決： 
修改tomcat-users.xml文件，這個文件在tomcat的安裝目錄下的conf目錄下，打開這個文件，我們可以看到如下信息：

Java代碼

1. <tomcat-users>
2. <!--
3. NOTE: By default, no user is included in the "manager-gui" role required
4. to operate the "/manager/html" web application. If you wish to use this app,
5. you must define such a user - the username and password are arbitrary.
6. -->
7. <!--
8. NOTE: The sample user and role entries below are wrapped in a comment
9. and thus are ignored when reading this file. Do not forget to remove
10. <!.. ..> that surrounds them.
11. -->
12. <!--
13. <role rolename="tomcat"/>
14. <role rolename="role1"/>
15. <user username="tomcat" password="tomcat" roles="tomcat"/>
16. <user username="both" password="tomcat" roles="tomcat,role1"/>
17. <user username="role1" password="tomcat" roles="role1"/>
18. -->
19. </tomcat-users>

我們在這里加上如下的一句話：

Java代碼

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

修改后的文件為：

Java代碼

1. <tomcat-users>
2. <!--
3. NOTE: By default, no user is included in the "manager-gui" role required
4. to operate the "/manager/html" web application. If you wish to use this app,
5. you must define such a user - the username and password are arbitrary.
6. -->
7. <!--
8. NOTE: The sample user and role entries below are wrapped in a comment
9. and thus are ignored when reading this file. Do not forget to remove
10. <!.. ..> that surrounds them.
11. -->
12. <!--
13. <role rolename="tomcat"/>
14. <role rolename="role1"/>
15. <user username="tomcat" password="tomcat" roles="tomcat"/>
16. <user username="both" password="tomcat" roles="tomcat,role1"/>
17. <user username="role1" password="tomcat" roles="role1"/>
18. -->
19. <user username="admin" password="admin" roles="admin,manager"/>
20. </tomcat-users>

重新啟動tomcat服務器，這時，我們就可以使用用戶名為admin，密碼為admin的用戶登錄tomcat的管理界面了，這樣，我們可以遠程管理tomcat了

 

tomcat7 請添加如下文件：

<role rolename="manager-gui"/>
  <role rolename="admin-gui"/>
  
  <user username="admin" password="admin" roles="manager-gui,admin-gui"/>
