ActiveMQ使用的是jetty服务器, 在ActiveMQ目录下的conf/jetty.xml文件，vim打开
<bean id="securityConstraint" class="org.eclipse.jetty.http.security.Constraint">
<property name="name" value="BASIC" />
<property name="roles" value="admin" />
<property name="authenticate" value="false" />
</bean>将property name为authenticate的属性value=”false” 改为”true”（现在的版本默认一般为true，然后默认账号密码都是admin），
控制台的登录用户名密码保存在conf/jetty-realm.properties文件中,内容如下:

admin: admin, admin设置的格式就是这样：
admin：admin， admin
用户名 : 密码 ,角色名
例如：
我要一个账号为master_admin，密码为123456的admin角色账号
master_admin：123456，admin
