ActiveMQ 与ActiveMQ-CPP

一天功夫终于知道怎么使用activeMQ的c++接口了。 花费时间最多的是不知道activemqcpp需要在activeMQ的基础上使用。

下面分别讲述activeMQ和activemqcpp的安装和使用。

一。 ActiveMQ的安装

      1. 下载 源包： http://activemq.apache.org/download-archives.html

       2. tar zxvf  apache-activemq-xxx.bin.tar.gz -C /usr/local
       3. cd apache-activemq-xxx/bin

       4. chmod 755 activemq

       5. 启动   ./activemq start

       启动后就可以查 看：  http://localhost:8161/admin, 默认 用户名和密码都是admin

 二。 安装ActiveMQ-CPP

          需要较多的依赖。参考 http://blog.csdn.net/lgh1700/article/details/51055784

（1）cppunit打开http://activemq.apache.org/cms/building.html页面，这里介绍了cms build时用到的依赖库。cppunit下载页面：https://sourceforge.net/projects/cppunit/files/cppunit/1.12.1/这里选择1.12.1版本，获取到下载地址后，在linux下可以用wget命令直接下载，或者下载完成后传到linux系统中。tar解压后，进入目录，编译三部曲，configure、make、make install（install需要root权限）：./configure --prefix=/usr/local/cppunit/makemake install执行完后在/usr/local/cppunit/目录下可以看到头文件和库文件。（2）aprapr的全称为Apache Portable Runtime（Apache可移植运行时），Apache旗下有很多开源软件。apr介绍页面：http://apr.apache.org/download.cgi这里选择最新的APR 1.5.2版本，地址为：http://mirrors.hust.edu.cn/apache//apr/apr-1.5.2.tar.gz同上，解压进入目录，三部曲：./configure --prefix=/usr/local/apr/makemake install（3）apr-util这里选择最新的APR-util 1.5.4版本，下载地址为：http://mirrors.hust.edu.cn/apache//apr/apr-util-1.5.4.tar.gz解压编译：./configure --prefix=/usr/local/aprutil --with-apr=/usr/local/apr/makemake install（4）apr-iconv这里选择最新的APR iconv 1.2.1版本，地址为：http://mirrors.hust.edu.cn/apache//apr/apr-iconv-1.2.1.tar.gz解压编译：./configure --prefix=/usr/local/apr-iconv/ --with-apr=/usr/local/apr/makemake install（5）openssl这里选择openssl 1.0.0a版本，下载地址为：http://www.openssl.org/source/openssl-1.0.0a.tar.gz解压编译：./config --prefix=/usr/local/openssl/makemake install若出现报错cms.pod around line 457: Expected text after =item, not a number在root权限下，执行rm -f /usr/bin/pod2man 然后重新make install（6）ActiveMQ-CPP这里选择最新的ActiveMQ-CPP 3.9.3版本，下载页面为：http://activemq.apache.org/cms/activemq-cpp-393-release.html解压编译：./configure --prefix=/usr/local/ActiveMQ-CPP --with-apr=/usr/local/apr/ --with-apr-util=/usr/local/aprutil --with-cppunit=/usr/local/cppunit --with-openssl=/usr/local/opensslmakemake install 这样，/usr/local/下有了ActiveMQ-CPP目录。 包含activemqcpp的头文件和lib文件

三。 示例

        启动ActiveMQ，然后启动activemqcpp的代码。 再查看http://localhost:8161/admin中的queue、topic等

以上代码即包含了生产者又包含了消费者。 使用ifdef实现分开编译。   将以上代码做两份，分别编译生产者和消费者。

在终端1中启动生产者。 会发现8161/admin中的queue中有event_queue, 并且有消息不断入队列；

另一个终端启动消费者，可以发现消息队列中消息在被消费。
