演示环境： Centos7、jdk8、activemq5.15.8 下载地址： http://activemq.apache.org/activemq-5158-release.html 解压： ```tar -zxvf apache-activemq-5.15.8-bin.tar.gz -C /var``` 修改目录名称 ```mv /var/apache-activemq-5.15.8/ /var/activemq/``` 启动： ```./bin/activemq start``` 停止：``` ./bin/activemq stop``` # 操作练习 1、创建一个systemd服务文件：``` vi /usr/lib/systemd/system/activemq.service``` 2、放入内容 ``` [Unit] Description=ActiveMQ service After=network.target [Service] Type=forking ExecStart=/var/activemq/bin/activemq start ExecStop=/var/activemq/bin/activemq stop User=root Group=root Restart=always RestartSec=9 StandardOutput=syslog StandardError=syslog SyslogIdentifier=activemq [Install] WantedBy=multi-user.target ``` 3、找到java命令所在的目录 ``` whereis java ``` 4、设置activemq配置文件/var/activemq/bin/env中的JAVA_HOME ``` # Location of the java installation # Specify the location of your java installation using JAVA_HOME, or specify the # path to the "java" binary using JAVACMD # (set JAVACMD to "auto" for automatic detection) JAVA_HOME="/usr/local/java/jdk1.8.0_181" JAVACMD="auto" ``` 5、通过systemctl管理activemq启停 * 启动activemq服务: ```systemctl start activemq``` * 查看服务状态: ```systemctl status activemq``` * 创建软件链接：``` ln -s /usr/lib/systemd/system/activemq.service /etc/systemd/system/multi-user.target.wants/activemq.service ``` * 开机自启: ```systemctl enable activemq``` * 检测是否开启成功(enable)： ```systemctl list-unit-files |grep activemq ``` 6、防火墙配置，Web管理端口默认为8161（admin/admin），通讯端口默认为61616 * 添加并重启防火墙 ``` firewall-cmd --zone=public --add-port=8161/tcp --permanent firewall-cmd --zone=public --add-port=61616/tcp --permanent systemctl restart firewalld.service ``` * 或者直接关闭防火墙: ```systemctl stop firewalld.service``` 7、修改web管理系统的部分配置,配置文件在```/var/activemq/conf``` * 端口修改 ``` <bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start">  <property name="host" value="0.0.0.0"/>  <property name="port" value="8161"/> </bean> ``` * 关闭登录 ``` <bean id="securityConstraint" class="org.eclipse.jetty.util.security.Constraint"> <property name="name" value="BASIC" /> <property name="roles" value="user,admin" />  <property name="authenticate" value="true" /> </bean> ``` * 其他配置: ```/var/activemq/conf/jetty-realm.properties``` ``` ## --------------------------------------------------------------------------- # 在此即可维护账号密码，格式： # 用户名:密码,角色 # Defines users that can access the web (console, demo, etc.) # username: password [,rolename ...] admin: admin, admin user: 123, user ``` 8、 JAVA客户端的使用 * 标准客户端使用 ``` <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-all</artifactId> <version>5.15.8</version> </dependency> ``` * Spring中使用: ```http://spring.io/guides/gs/messaging-jms/``` ``` <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jms</artifactId> <version>5.1.3.RELEASE</version> </dependency> <dependency> <groupId>org.apache.activemq</groupId> <artifactId>activemq-broker</artifactId> <version>5.15.8</version> <exclusions> <exclusion> <artifactId>geronimo-jms_1.1_spec</artifactId> <groupId>org.apache.geronimo.specs</groupId> </exclusion> </exclusions> </dependency> ```
