本系列暂定共四篇文章：

1.离线部署Centreon 22.10.X -Central端

2.离线部署Centreon 22.10.X -Poller端

3.离线迁移Centreon2.8.X到22.10.X

4.No parent platform was found for : ‘poller1’@’IP’

当执行poller注册到centreon脚本时，碰到如下报错：

[root@centron-upgrade-test2 ~]# /usr/share/centreon/bin/registerServerTopology.sh -u admin -t poller -h 192.168.26.208 -n poller1
Please enter the password of 192.168.26.208: 

  Summary of the information that will be sent:

  Api Connection:

  Pending Registration Server:
  name: poller1
  hostname: centron-upgrade-test2
  type: poller
  address: 192.168.26.201

Do you want to register this server with the previous information? (y/n): y
2023-06-13 21:59:38-04:00 - ERROR - http://192.168.26.208:80: {"message":"No parent platform was found for : 'poller1'@'192.168.26.201'"}

这一般是cetral端 也就是server端的IP地址修改导致的。 我们可以通过登录数据库，执行以下语句查询就会发现，数据库里面的 IP 不是192.168.26.208 而是192.168.26.200。 这是因为我操作过修改IP地址。

[root@centreon-upgrade-test ~]# mysql -u root -p

Database changed

MariaDB [centreon]> select * from platform_topology;
+----+----------------+-----------------------+---------+---------+-----------+---------+-----------+
| id | address        | hostname              | name    | type    | parent_id | pending | server_id |
+----+----------------+-----------------------+---------+---------+-----------+---------+-----------+
|  2 | 192.168.26.200 | centreon-upgrade-test | Central | central |      NULL | 0       |         1 |
+----+----------------+-----------------------+---------+---------+-----------+---------+-----------+
1 row in set (0.000 sec)

那么如何解决呢？我们可以在web端直接修改central的地址为现在的实际IP地址，然后再次查询，就会发现数据库产生了更新。

保存后就发生了变更。再次去查询数据库，发现已经同步。

MariaDB [centreon]> select * from platform_topology;
+----+----------------+-----------------------+---------+---------+-----------+---------+-----------+
| id | address        | hostname              | name    | type    | parent_id | pending | server_id |
+----+----------------+-----------------------+---------+---------+-----------+---------+-----------+
|  2 | 192.168.26.208 | centreon-upgrade-test | Central | central |      NULL | 0       |         1 |
+----+----------------+-----------------------+---------+---------+-----------+---------+-----------+
1 row in set (0.001 sec)

重新返回poller端，重新注册，看看效果：

[root@centron-upgrade-test2 ~]# /usr/share/centreon/bin/registerServerTopology.sh -u admin -t poller -h 192.168.26.208 -n poller1
Please enter the password of 192.168.26.208: 

  Summary of the information that will be sent:

  Api Connection:
  username: admin
  password: ******
  target server: 192.168.26.208

  Pending Registration Server:
  name: poller1
  hostname: centron-upgrade-test2
  type: poller
  address: 192.168.26.201

Do you want to register this server with the previous information? (y/n): y
2023-06-13 22:20:53-04:00 - INFO - The CURRENT NODE poller: '[email protected]' linked to TARGET NODE: http://192.168.26.208:80 has been added

添加成功！

可以参考这篇文章： 分布式监控系列：离线部署Centreon 22.10.X -Poller端 – 辣条网 (latiao.org)

如果无法启动poller，可以查看下/var/log/centreon-gorgone的日志，是否有如下报错

2023-06-13 23:11:17 - ERROR - [proxy] Send message problem for '5': fingerprint changed for target 'tcp://192.168.26.201:5556' [id: 1] [old fingerprint: 9y82Tby25xrKNt5hAHtKwf9Faboe_qeDUzoglu8akZE] [new fingerprint: qlxbKYO0xaggUYOBzAW3H2HbmrDr4oWv8FLTG3NGzRw]

如果出现了这个错误，我们更新下gorgone的指纹，并且重启gorgone的服务即可：

[root@centreon-upgrade-test centreon-gorgone]# sqlite3 /var/lib/centreon-gorgone/history.sdb
