1.配置内存
bin中activemq.bat 中的第一行 加上 :
REM 配置内存
set ACTIVEMQ_OPTS=-Xms1G -Xmx1G2.修改控制台密码
1.打开conf/jetty.xml，
将property name为authenticate的属性value="false" 改为"true"，高版本的已经默认为true了。
2.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:
# Defines users that can access the web (console, demo, etc.)# username: password [,rolename ...]admin: admin, admin
值得注意的是 用户名和密码的格式是：用户名 : 密码 ,角色名
3.修改客户端连接密码
1.修改activemq.xml配置,需要新增一个插件,在<broker>节点里面<systemUsage>节点前面添加如下
或者直接修改为（即直接将username和password赋值，所赋的值即为用户名和密码。如果使用这一种方式的话，下面的第二步则不需要了）：
2.用户名密码文件为:credentials.properties
