[root@yxq ~]# pwd
/root
[root@yxq ~]# mkdir activemq
[root@yxq ~]# cd activemq/
上传安装包到服务器
解压安装
[root@yxq activemq]# ls
apache-activemq-5.11.1-bin.tar.gz
[root@yxq activemq]# tar -zxvf apache-activemq-5.11.1-bin.tar.gz
[root@yxq activemq]# mv apache-activemq-5.11.1 activemq
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）
[root@yxq activemq]# chmod 755 /root/activemq/activemq-01/bin/activemq
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：
[root@yxq activemq]# vi /root/activemq/activemq-01/conf/jetty.xml
<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>
[root@yxq activemq]# vi /etc/sysconfig/iptables-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
[root@yxq activemq]# service iptables restart
启动mq
[root@yxq activemq]# /root/activemq/activemq-01/bin/activemq start
INFO: Loading '/root/activemq/activemq-01/bin/env'
INFO: Using java '/usr/jdk/bin/java'
INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details
INFO: pidfile created : '/root/activemq/activemq-01/data/activemq.pid' (pid '10232')
[root@yxq activemq]#
在浏览器打开访问
f以admin/admin登录
登录成功
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：
在 conf/activemq.xml 文件中在broker 标签最后加入以下内容即可：
[root@yxq activemq]# vi /root/activemq/activemq-01/conf/activemq.xml<plugins>
<simpleAuthenticationPlugin>
<users>
<authenticationUser username="yixq" password="yxq123456"
groups="users,admins" />
</users>
</simpleAuthenticationPlugin>
</plugins>
定义了一个yixq 用户，密码为 yxq123456，角色为 users,admins
设置 admin 的用户名和密码:
[root@yxq activemq]# vi /root/activemq/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
[root@yxq activemq]# vi /root/activemq/activemq-01/conf/jetty-realm.properties# username: password [,rolename ...]
admin: yxq123456, admin
用户名 : 密码 ,角色名
重启，再登录就是新设置的密码登录
[root@yxq activemq]# /root/activemq/activemq-01/bin/activemq restart
设置开机启动：
[root@yxq activemq]# vi /etc/rc.local
