又就直接修改 沒有就添加 我的哪個文件里都沒有?

在tomcat目錄下conf文件夾中的tomcat-users.xml?文件中

這兩個<tomcat-users></tomcat-users>標簽之間，加上以下內容：

<role?rolename="manager-gui"/>
<user?username="tomcat"?password="tomcat"?roles="manager-gui"/>

將tomcat-users.xml?文件內容改為

<?xml?version='1.0'?encoding='utf-8'?>
<tomcat-users>
<role?rolename="tomcat"/>
<role?rolename="role1"/>
<role?rolename="manager"/>
<role?rolename="admin"/>
<user?username="admin"?password="admin"?roles="admin,manager"/>
<user?username="tomcat"?password="tomcat"?roles="tomcat"/>
<user?username="role1"?password="tomcat"?roles="role1"/>
<user?username="both"?password="tomcat"?roles="tomcat,role1"/>
</tomcat-users>?

找到username是admin的進行修改
