本文主要是介绍Linux apache-activemq安装及配置，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
1. apache-activemq安装
备注：apache-activemq安装时JDK必须在1.5以，否则不能访问。
（1）从官网下载Activemq Linux包http://activemq.apache.org/download.html.这儿我下载的是 apache-activemq-5.4.3-bin.tar.gz
（2）解压包
| tar zxvf apache-activemq-5.4.3-bin.tar.gz |
（3）进入解压后的文件夹apache-activemq-5.4.3-bin中的bin目录
| cd apache-activemq-5.4.3-bin/bin目录 |
（4）在启动前先配置activemq。在bin目录下执行
| ./activemq setup /root/.activemqrc |
（5）提高activemq的权限
| chmod 600 /root/.activemqrc |
（6）启动activemq
| ./activemq start |
(7)最后http访问出现以下代表成功
http://IP:61616/若出现下边内容则说明安装成功(备注在启动前主要要开启端口61616)
2. apache-activemq自启动设置
修改启动脚本/opt/activemq/bin/activemq，将开头处改为：
| #!/bin/sh ### BEGIN INIT INFO # Provides: activemq # Required-Start: $remote_fs $syslog # Required-Stop: $remote_fs $syslog # Default-Start: 2 3 4 5 # Default-Stop: 0 6 # Short-Description: ActiveMQ server ### END INIT INFO
|
然后创建软链接：
| # ln -s /opt/activemq/bin/activemq /etc/init.d/ |
然后进入系统开机自启动配置文件rc.local的编辑界面
| vi /etc/rc.local |
然后插入启动语句：
| bash /etc/init.d/activemq start |
最后保存
3. apache-activemq调优配置
1. JVM内存设置：
注意不要修改%ACTIVEMQ_HOME%/bin目录下activemq文件， 要改 /root/.activemqrc 文件（如果没有找到.activemqrc文件，运行一次activemq就自动生成了），找到文件中的ACTIVEMQ_OPTS_MEMORY选项，设置为：
ACTIVEMQ_OPTS_MEMORY="-Xms2048M -Xmx2048M"
注意不要多余的空格。
2. activemq参数配置，打开%ACTIVEMQ_HOME%/confg目录下的activemq.xml文件，进行如下修改（红色部分为修改的内容）。

For better performances use VM cursor and small memory limit.
For more information, see:

The managementContext is used to configure how ActiveMQ is exposed in
JMX. By default, ActiveMQ uses the MBean server that is started by
the JVM. For more information, see:
http://activemq.apache.org/jmx.html

Configure message persistence for the broker. The default persistence
mechanism is the KahaDB store (identified by the kahaDB tag).

The transport connectors expose ActiveMQ over a given protocol to
