CentOS 6下ActiveMQ 5.5安裝及使用MySQL

從http://activemq.apache.org/download.html下載ActiveMQ的最新版本，當前是5.50，把包apache-activemq-5.5.0-bin .tar.gz拷貝到/home/software/apache-activemq目錄下，執行以下命令：

 

# 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作為訊息的儲存，修改 /usr/local/activemq/conf/activemq.xml如下：

在啟動前，需要建立資料庫 activemq，並且不要參照activemq-jdbc.xml配置 <property name="poolPreparedStatements" value="true"/>。

# bin/activemq start

從瀏覽器中開啟：，發給訊息測試一下，可以正常發送的話，就應該沒有什麼大問題。
