#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 ```bash 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 ```bash 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 ```bash apache-activemq-5.15.2\bin\win64\activemq.bat ``` 也可以注册服务 ```bash apache-activemq-5.15.2\bin\win64\InstallService.bat ``` ##2.3 退出 ```bash 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。 ```bash 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 ```xml <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。 ```bash ## --------------------------------------------------------------------------- ## Licensed to the Apache Software Foundation (ASF) under one or more ## contributor license agreements.
