启动和停止实例
“/www/wwwroot/service/apache-artemis-2.19.0/bin/mybroker/bin/artemis-service” start
netstat -anpt
查看端口使用:
netstat -anpt
访问控制台
1)修改 mybroker/etc/Jolokia -access.xml,添加一条allow-origin的访问权限设置
<allow-origin>*://192.168.0.16*</allow-origin>
2)修改mybroker/etc/bootstrap.xml,localhost改为服务器的ip
<web bind="http://192.168.0.16:8161" path="web">
<app url="activemq-branding" war="activemq-branding.war"/>
<app url="artemis-plugin" war="artemis-plugin.war"/>
<app url="console" war="console.war"/>
</web>
3)重启一下broker实例
"/www/wwwroot/service/apache-artemis-2.19.0/bin/mybroker/bin/artemis-service" restart
最后访问:
http://192.168.0.16:8161/console 来使用控制台.
客户端通信:
ip:192.168.0.16
port:1883
