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：

<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
