2. ActiveMQ-Artemis安装/配置

http://activemq.apache.org/components/artemis/download/

源包和二进制包的URL：

pwd
/opttar -xzf /media/SDA1/apache-artemis-2.12.0-bin.tar.gz

校验：

ls(among other things…) apache-artemis-2.12.0

创建一个新的Linux用户组`activemq`

addgroup --quiet --system activemq

创建一个新的Linux用户`activemq`

adduser --quiet --system --ingroup activemq \
--no-create-home --disabled-password activemq

更改目录“/opt/apache-artemis-2.12.0”的所有权

chown -R activemq:activemq /opt/activemq

导航到“bin”目录

cd apache-artemis-2.12.0/bin

校验：

./artemis

如果看到以下输出，则表明已准备好安装代理：

usage: artemis <command> [<args>]The most commonly used artemis commands are:address     Address tools group (create|delete|update|show) (example ./artemis address create)browser     It will browse messages on an instanceconsumer    It will consume messages from an instancecreate      creates a new broker instancedata        data tools group (print) (example ./artemis data print)help        Display help informationmask        mask a password and print it outmigrate1x   Migrates the configuration of a 1.x Artemis Brokerproducer    It will send messages to an instancequeue       Queue tools group (create|delete|update|stat|purge) (example ./artemis queue create)See 'artemis help <command>' for more information on a specific command.

创建代理

./artemis create ActiveMQ-Odroid-110 --user=admin --password=admin \
--http-host 0.0.0.0 --relax-jolokia

...安装将出现一个额外的提示（只需键入“Y”，然后按Enter）：

--allow-anonymous | --require-login: is a mandatory property!
Allow anonymous access?, valid values are Y,N,True,FalseY      <--- Enter

其余输出：

Auto tuning journal ...
done! Your system can make 1.61 writes per millisecond,
your journal-buffer-timeout will be 620000You can now start the broker by executing:"/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis" run
Or you can run the broker in the background using:"/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service" start"/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service"
Usage: ./artemis-service {start|stop|restart|force-stop|status}

启动代理实例

"/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis" run

现在，打开Web浏览器并将其指向以下网站：

http://<IP of the broker>:8161

如果您看到以下网页，则代理实例已启动并成功运行：

"/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service" start

输出：

Starting artemis-service
artemis-service is now running (14289)

校验：

ps -ef| grep 14289

输出：

再次注销/登录到Web控制台，以确保一切仍然正常。

"/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service" stop

至此，我们准备为代理实例创建一个新的systemd服务。

touch /etc/systemd/system/activemq-artemis.servicechmod 644 /etc/systemd/system/activemq-artemis.servicevim /etc/systemd/system/activemq-artemis.service

将以下行添加到文件中：

[Unit]Description=Apache ActiveMQ Artemis
After=network.target[Service]Type=forking
User=activemq
Group=activemqExecStart=/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service start
ExecStop=/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service stop[Install]
WantedBy=multi-user.target

加载/启动服务：

systemctl daemon-reloadsystemctl start activemq-artemis

启用服务（以便它可以在系统重新启动后幸存）：

systemctl enable activemq-artemis

输出：

Created symlink /etc/systemd/system/multi-user.target.wants/
activemq-artemis.service → /etc/systemd
/system/activemq-artemis.

通过系统服务进行验证：

systemctl status activemq-artemis

输出应类似于以下内容：

Loaded: loaded (/etc/systemd/system/activemq-artemis.service; enabled; vendor preset: enabled)Active: active (running) since Sat 2020-05-02 16:17:52 UTC; 34s agoProcess: 2894 ExecStart=/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service start (code=exited, staMain PID: 2919 (java)Tasks: 50 (limit: 3838)CGroup: /system.slice/activemq-odroid-110.service└─2919 java -XX:+PrintClassHistogram -XX:+UseG1GC -XX:+UseStringDeduplication -Xms512M -Xmx2G -Dhawtio.realm=May 02 16:17:30 odroid systemd[1]: Starting Apache ActiveMQ Artemis...May 02 16:17:30 odroid artemis-service[2894]: Starting artemis-serviceMay 02 16:17:52 odroid artemis-service[2894]: artemis-service is now running (2919)May 02 16:17:52 odroid systemd[1]: Started Apache ActiveMQ Artemis.

（可选）使用代理的状态报告进行验证：

/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service status

输出应类似于以下内容：

artemis-service is running (16934)

测试系统停止服务：

systemctl stop activemq-odroid-110

通过系统服务进行验证：

systemctl status activemq-odroid-110

在过去的几行输出应该类似于如下：

May 02 16:35:13 odroid artemis-service[4031]: Gracefully Stopping artemis-serviceMay 02 16:35:14 odroid systemd[1]: activemq-odroid-110.service: Main process exited, code=exited, status=143/n/aMay 02 16:35:14 odroid systemd[1]: activemq-odroid-110.service: Failed with result 'exit-code'.May 02 16:35:14 odroid systemd[1]: Stopped Apache ActiveMQ Artemis.

验证与代理的状态报告：

/opt/apache-artemis-2.12.0/bin/ActiveMQ-Odroid-110/bin/artemis-service status

输出应类似于以下内容：

artemis-service is stopped
