obd demo执行命令的时候提示prometheus端口占用了

OceanBase 技术问题
,
#1

【 使用环境 】测试环境
【 OB or 其他组件 】
【 使用版本 】oceanbase 社区版 oceanbase-all-in-one 4.2.1
【问题描述】执行obd demo提示端口（9090）被占用，但是这个服务通过parameter.yaml文件修改以后，再次执行obd demo还是报错，是不是什么东西还要加载一下？

【复现路径】最小化执行obd demo报错

后面是默认端口，可以自定义修改的
obd demo --oceanbase-ce.Prometheus=9091。可指定端口部署

您给的命令执行以后还是报一样的错误

@ AntTech_RXKBOI

9090端口为操作系统自带的管理界面服务所占用，名叫"cockpit"。
通常来说，管理员并不需要此服务，并且例如我公司，默认基线标准里，是将其禁用的。

请在OS执行(记得按照顺序哦，因为服务有依赖关系)

systemctl stop cockpit.socket
systemctl stop cockpit.service
systemctl disable cockpit.socket
systemctl disable cockpit.service

而后进行OB部署，就可以畅游OB了。

关于Cockpit ,是红帽开发的网页版图像化服务管理工具，优点是无需中间层，且可以管理多种服务。

@AntTech_RXKBOI 试试哦。

#8

就是这个问题导致的，之前杀pid不能直接杀掉，感谢大佬，解决了 :grinning:

#9

杀掉可能OS重启后就再起来了，可以考虑按照给的命令顺序，禁用即可。
欢迎采纳，共同交流。

#10

这边刚才测试一下 命令是可用的，可能是是–为中文导致的这边刚才删除重新填写后命令是可用的
