我们可以通过图形用户界面来管理tomcat，启动tomcat，在地址栏中输入：
- http://localhost:8080
就可以看见tomcat的欢迎页面，点击左边的tomcat manager 就会出现一个对话框，需要输入用户名和密码，当忘记最开始安装tomcat时的用户名和密码时，我们可以通过以下方杰来解决：
修改tomcat-users.xml文件，这个文件在tomcat的安装目录下的conf目录下，打开这个文件，我们可以看到如下信息：
- <tomcat-users>
- <!–
- NOTE: By default, no user is included in the “manager-gui” role required
- to operate the “/manager/html” web application. If you wish to use this app,
- you must define such a user – the username and password are arbitrary.
- –>
- <!–
- NOTE: The sample user and role entries below are wrapped in a comment
- and thus are ignored when reading this file. Do not forget to remove
- <!.. ..> that surrounds them.
- –>
- <!–
- <role rolename=“tomcat”/>
- <role rolename=“role1”/>
- <user username=“tomcat” password=“tomcat” roles=“tomcat”/>
- <user username=“both” password=“tomcat” roles=“tomcat,role1”/>
- <user username=“role1” password=“tomcat” roles=“role1”/>
- –>
- </tomcat-users>
我们在这里加上如下的一句话：
- <user username=“admin” password=“admin” roles=“admin,manager”/>
修改后的文件为：
- <tomcat-users>
- <!–
- NOTE: By default, no user is included in the “manager-gui” role required
- to operate the “/manager/html” web application. If you wish to use this app,
- you must define such a user – the username and password are arbitrary.
- –>
- <!–
- NOTE: The sample user and role entries below are wrapped in a comment
- and thus are ignored when reading this file. Do not forget to remove
- <!.. ..> that surrounds them.
- –>
- <!–
- <role rolename=“tomcat”/>
- <role rolename=“role1”/>
- <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”/>
- </tomcat-users>
重新启动tomcat服务器，这时，我们就可以使用用户名为admin，密码为admin的用户登录tomcat的管理界面了，这样，我们可以远程管理tomcat了
