设置一
<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
<role rolename="tomcat"/>
<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<user username="tomcat" password="tomcat" roles="tomcat"/>
<user username="role1" password="tomcat" roles="role1"/>
<user username="both" password="tomcat" roles="tomcat,role1"/>
<user username="admin" password="" roles="admin,manager"/>
</tomcat-users> 

如果设置不成功 可以尝试下面一种方式

 

 

<?xml version='1.0' encoding='utf-8?>

<tomcat-users>

<role rolename="tomcat"/>

<role rolename="role1"/>
<role rolename="manager"/>
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/> 
<user username="tomcat" password="tomcat" roles="admin,manager,role1,tomcat,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" />

</tomcat-users>
