obd安装obagent，如何修改默认端口

OceanBase 技术问题
#1

【 使用环境 】 测试环境
【 OB or 其他组件 】obagent
【 使用版本 】V4.2.1.7
【问题描述】
使用obd部署，因为我的机器上部署过oms，8088、8089已经被使用了。
安装obagent和ocp组件的时候报端口冲突。

[2024-08-07 08:24:10.866] [ERROR] OBD-1001: 127.0.0.1:8088 port is already used
[2024-08-07 08:24:10.961] [INFO] [ERROR] OBD-1001: 127.0.0.1:8089 port is already used
[2024-08-07 08:24:10.961] [INFO] [ERROR] OBD-1001: 127.0.0.1:8088 port is already used

示例参数文件中没有看到端口相关的参数。

obagent:
  depends:
    - oceanbase-ce
  servers:
    - name: server1
      # Please don't use hostname, only IP can be supported
      ip: 172.19.33.2
    - name: server2
      ip: 172.19.33.3
    - name: server3
      ip: 172.19.33.4
  global:
    home_path: /root/obagent

有人修改过吗？如何修改obagent的2个端口，使用哪两个参数？

参考目录~/.oceanbase-all-in-one/obd/usr/obd/example/obagent/下的参数文件说明
你试试手动填上这俩参数修改端口号

#4

我暂时把原来的oms停了，这步是过去了。
但是第一次安装的时候已经创建了ocp_meta库，第二次obagent安装成功了，但是连ocp_meta一直连不上，用日志里面的密码连报密码错误。

第一次安装的时候日志：

哪里能获取到ocp_meta的密码吗？修改下是不是就可以启动了。
还是只能删了重新部署

#5

原本就存在oms的机器，是又准备安装个ocp么

#6

这台服务器之前安装过oms，前面说的端口冲突的问题，我把oms停了，现在agent安装成功了。

但是第一次安装的时候ocp_meta租户建成功了，agent因为端口冲突失败了。
第二次，把原来的oms停掉，再次安装，agent安装成功了，但是启动ocp失败，看日志是连不上ocp_meta库，手动连接测试密码不对。这个租户是第一次安装的时候就创建了的，这个密码哪里能看到吗？怎么修改下？

#7

ocp_meta租户root密码设置的随机么，正常情况下这个密码会在安装完成后罗列出来，你可以看看yaml文件里现在有没有，如果没有就需要重新安装了

#8

ocp_monitor的密码都能看到，元数据库的密码没找到

#9

可能需要你重装了 :joy:
