1.下载安装 ActiveMQ
ActiveMQ 官网下载地址：http://activemq.apache.org/download.html
可根据操作系统不同，下载不同版本，此处我下载的是apache-activemq-5.15.2-bin.tar.gz linux 版本。
需要注意下依赖的jdk版本
2.启动 ActiveMQ
2.1 下载后需要先解压
tar -xvf apache-activemq-5.15.2-bin.tar.gz
2.2 目录结构
bin 存放的是脚本文件
conf 存放的是基本配置文件
data 存放的是日志文件
docs 存放的是说明文档
examples 存放的是简单的实例
lib 存放的是activemq所需jar包
webapps 用于存放项目的目录
2.3 启动
cd cd /home/sherlocky/apache-activemq-5.15.2/bin
./activemq start
输入命令之后，会提示创建了一个进程号，这就说明服务已经成功启动了。
如果是windows系统，可以通过以下命令启动
apache-activemq-5.15.2\bin\win64\activemq.bat
也可以注册服务
apache-activemq-5.15.2\bin\win64\InstallService.bat
2.3 退出
cd cd /home/sherlocky/apache-activemq-5.15.2/bin
./activemq stop
可以将以上命令写成 sh 方便执行。
3.配置
ActiveMQ 默认启动时，启动了内置的jetty服务器，提供一个用于监控ActiveMQ的admin应用。
http://127.0.0.1:8161/admin/
默认账号：admin/admin
3.1 authenticate
ActiveMQ 使用的是jetty服务器, 打开{ACTIVEMQ_HOME}/conf/jetty.xml文件，找到
<bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint">
<property name="name" value="BASIC" />
<property name="roles" value="user,admin" />
<!-- set authenticate=false to disable login -->
<property name="authenticate" value="true" />
</bean>
<bean id="adminSecurityConstraint" class="org.eclipse.jetty.util.security.Constraint">
<property name="name" value="BASIC" />
<property name="roles" value="admin" />
<!-- set authenticate=false to disable login -->
<property name="authenticate" value="true" />
</bean>
低版本的authenticate的属性默认为false 需要改为true，高版本的已经默认为true，忽略即可。
3.2 修改控制台密码
控制台的登录用户名密码配置在 {ACTIVEMQ_HOME}/conf/jetty-realm.properties文件中。

user: user, user
需要注意的是：用户名和密码的格式是：username: password [,rolename ...] 即 用户名: 密码, 角色
3.3 消息消费者密码
(1) 修改{ACTIVEMQ_HOME}/conf/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：
<plugins>
<simpleAuthenticationPlugin>
<users>
<authenticationUser username="${activemq.username}" password="${activemq.password}" groups="users,admins"/>
</users>
</simpleAuthenticationPlugin>
</plugins>
(2) 消费者密码配置在 {ACTIVEMQ_HOME}/conf/credentials.properties文件中

## ---------------------------------------------------------------------------
# Defines credentials that will be used by components (like web console) to access the broker
activemq.username=system
activemq.password=manager
guest.password=password
这样配置后，在客户端调用处就需要设置密码才能连接，以 java 为例：
// 建立ConnectionFactory工厂对象，需要填入用户名，密码，以及连接的地址
ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(
"system",// ActiveMQConnectionFactory.DEFAULT_USER,
"manager",// ActiveMQConnectionFactory.DEFAULT_PASSWORD,
"tcp://localhost:61616");
