apisix reload报错：prometheus端口占用

[lianfulei]

9094端口没有被占用，我这个完全确认的。

apisix prometheus配置如下
prometheus: # Plugin: prometheus
export_uri: /apisix/prometheus/metrics # Set the URI for the Prometheus metrics endpoint.
metric_prefix: apisix_ # Set the prefix for Prometheus metrics generated by APISIX.
enable_export_server: true # Enable the Prometheus export server.
export_addr: # Set the address for the Prometheus export server.
ip: 0.0.0.0 # Set the IP.
port: 9094 # Set the port.

reload后报错如下
2025/01/07 11:15:36 [notice] 16914#16914: signal process started
2025/01/07 11:15:36 [emerg] 16924#16924: bind() to 0.0.0.0:9094 failed (98: Address already in use)

The error message indicates that the port 9094 is already in use, even though you have confirmed that it is not. This could be due to a few reasons:

1. Zombie Processes: Sometimes, a process that was using the port might not have terminated properly. You can check for any lingering processes using the command:

   lsof -i :9094

   If you find any process using the port, you can terminate it using:

   kill -9 <PID>

2. Firewall or Network Configuration: Ensure that there are no firewall rules or network configurations that might be causing a false positive on port availability.

3. APISIX Configuration: Double-check your APISIX configuration to ensure there are no conflicting settings that might be causing the issue. For example, ensure that no other service or plugin is configured to use the same port.

4. System Caching: Sometimes, the system might cache port usage information. Restarting the system or the network service might help clear this cache.

If none of these solutions resolve the issue, consider changing the port to another number to see if the problem persists.

错误消息表明该端口9094已被使用，即使您已确认它没有被使用。这可能是由于以下几个原因造成的：

1. 僵尸进程：有时，使用端口的进程可能未正确终止。您可以使用以下命令检查是否有任何残留进程：

   lsof -i :9094

   如果发现任何进程正在使用该端口，则可以使用以下命令终止它：

   kill -9 <PID>

2. 防火墙或网络配置：确保没有防火墙规则或网络配置可能导致端口可用性出现误报。

3. APISIX 配置：仔细检查您的 APISIX 配置，确保没有可能导致问题的冲突设置。例如，确保没有其他服务或插件配置为使用同一端口。

4. 系统缓存：有时，系统可能会缓存端口使用信息。重新启动系统或网络服务可能有助于清除此缓存。

如果这些解决方案都不能解决问题，请考虑将端口更改为其他号码，看看问题是否仍然存在。
