CentOS 6下ActiveMQ 5.5安装及使用MySQL

从http://activemq.apache.org/download.html下载ActiveMQ的最新版本，当前是5.50，把包apache-activemq-5.5.0-bin .tar.gz拷贝到/home/software/apache-activemq目录下，执行以下命令：

# cd /home/software/apache-activemq

# tar zxvf  apache-activemq-5.5.0-bin .tar.gz

# cp -a  apache-activemq-5.5.0 /usr/local/activemq

# cd  /usr/local/activemq

我使用mysql作为消息的存储，修改 /usr/local/activemq/conf/activemq.xml如下：

在启动前，需要创建数据库 activemq，并且不要参照activemq-jdbc.xml配置 <property name="poolPreparedStatements" value="true"/>。

# bin/activemq start

从浏览器中打开：，发给消息测试一下，可以正常发送的话，就应该没有什么大问题。
