ActiveMQ 的安装与使用(单节点)

IP:192.168.4.101

环境:CentOS 6.6、JDK7

1 安装 JDK 并配置环境变量(略)

JAVA_HOME=/usr/local/java/jdk1.7.0_72

2 下载 Linux 版的 ActiveMQ(当前最新版 apache-activemq-5.11.1-bin.tar.gz

$ wget http://apache.fayea.com/activemq/5.11.1/apache-activemq-5.11.1-bin.tar.gz

3 解压安装

$ tar -zxvf apache-activemq-5.11.1-bin.tar.gz

$ mv apache-activemq-5.11.1 activemq-01

如果启动脚本 activemq 没有可执行权限,此时则需要授权(此步可选)

$ cd /home/wusc/activemq-01/bin/

$ chmod 755 ./activemq

4 防火墙中打开对应的端口

ActiveMQ 需要用到两个端口

一个是消息通讯的端口(默认为 61616)

一个是管理控制台端口(默认为 8161)可在 conf/jetty.xml 中修改,如下:

<bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start"> <!-- the default port number for the web console -->

<property name="host" value="0.0.0.0"/> <property name="port" value="8161"/>

</bean>

# vi /etc/sysconfig/iptables

添加:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 61616 -j ACCEPT 

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8161 -j ACCEPT

重启防火墙:

# service iptables restart

5 启动

$ cd /home/wusc/activemq-01/bin $ ./activemq start

6 打开管理界面:http://192.168.4.101:8161

默认用户名和密码为:admin/admin

7 安全配置(消息安全)

ActiveMQ 如果不加入安全机制的话,任何人只要知道消息服务的具体地址(包括 ip,端口,消息地址[ 队列或者主题地址 ] , ) ,都可以肆无忌惮的发送、接收消息。关于  ActiveMQ  安装配置http://activemq.apache.org/security.html

ActiveMQ 的消息安全配置策略有多种,我们以简单授权配置为例:

conf/activemq.xml 文件中在 broker 标签最后加入以下内容即可:

$ vi /home/wusc/activemq-01/conf/activemq.xml

<plugins>

<simpleAuthenticationPlugin>

<users>

 <authenticationUser username="wusc" password="wusc.123" groups="users,admins"/>

</users>

</simpleAuthenticationPlugin>

</plugins>

定义了一个 wusc 用户,密码为 wusc.123,角色为 users,admins

设置 admin 的用户名和密码: $ vi /home/wusc/activemq-01/conf/jetty.xml

<bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint"> <property name="name" value="BASIC" />

<property name="roles" value="admin" /> <property name="authenticate" value="true" />

</bean>

确保 authenticate 的值为 true(默认)

控制台的登录用户名密码保存在 conf/jetty-realm.properties 文件中,内容如下:

 $ vi /home/wusc/activemq-01/conf/jetty-realm.properties

# Defines users that can access the web (console, demo, etc.)

# username: password [,rolename ...]

admin: wusc.123, admin

注意:用户名和密码的格式是用户名 : 密码 ,角色名

重启:

$ /home/wusc/activemq-01/bin/activemq restart

设置开机启动:

# vi /etc/rc.d/rc.local

加入以下内容

## ActiveMQ

su - wusc -c ‘/home/wusc/activemq-01/bin/activemq start‘
