  • ActiveMQ安装与使用

    一 .安装运行ActiveMQ：

    1.下载activemq

    wget http://archive.apache.org/dist/activemq/apache-activemq/5.9.0/apache-activemq-5.9.0-bin.tar.gz

    2.解压

    tar -xf apache-activemq-5.9.0-bin.tar.gz

    [zcw@g1 ~]$ cd apache-activemq-5.9.0

    [zcw@g1 apache-activemq-5.9.0]$ cd bin/

    3.运行：

    [zcw@g1 bin]$ activemq start

    三种运行方式：
    (1)普通启动 ./activemq start
    (2)启动并指定日志文件 ./activemq start >tmp/smlog
    (3)后台启动方式nohup ./activemq start >/tmp/smlog
    前两种方式下在命令行窗口关闭时或者ctrl+c时导致进程退出，采用后台启动方式则可以避免这种情况

    管理后台为：

    http://ip:8161/admin/

     

    4.检查已经启动
     ActiveMQ默认采用61616端口提供JMS服务，使用8161端口提供管理控制台服务，执行以下命令以便检验是否已经成功启动ActiveMQ服务。
    打开端口：nc -lp 61616 &
    查看哪些端口被打开 netstat -anp
    查看61616端口是否打开： netstat -an | grep 61616
    检查是否已经启动：
    (1).查看控制台输出或者日志文件 
    (2).直接访问activemq的管理页面：http://localhost:8161/admin/

    5.关闭
    如果开启方式是使用(1)或(2)，则直接ctrl+c或者关闭对应的终端即可 
    如果开启方式是(3),则稍微麻烦一点： 
    先查找到activemq对应的进程： 
    ps -ef | grep activemq 
    然后把对应的进程杀掉，假设找到的进程编号为 168168 
    kill 168168 

    二.创建ActiveMQ的Eclipse项目并运行

    1）P2P方式

    到中心仓库（

    http://search.maven.org/

    ）里面找到：activemq-core

    pom.xml:
