influxdb怎么改端口

在 InfluxDB 中，可以通过修改配置文件来改变端口。下面是具体步骤：

1. 打开配置文件

在 Linux 系统中，InfluxDB 的默认配置文件路径为 /etc/influxdb/influxdb.conf。在 Windows 系统中，InfluxDB 的默认配置文件路径为 C:\Program Files\InfluxDB\influxdb.conf。

打开对应系统中的配置文件。

2. 修改端口号

在配置文件中找到 [http] 部分。可以看到默认情况下，InfluxDB 使用的是 8086 端口。如果需要更改端口，只需要将 port 值修改为新的端口号即可。

例如，将端口号改为 8888：

[http]
  # Determines whether HTTP endpoint is enabled.
  enabled = true

  # The bind address used by the HTTP service.
  bind-address = ":8086"

  # Determines whether HTTP authentication is enabled.
  auth-enabled = false

  # The default realm sent back when issuing a basic auth challenge.
  realm = "InfluxDB"

  # Determines whether HTTPS is enabled.
  https-enabled = false

  # The SSL certificate to use when HTTPS is enabled.
  https-certificate = "/etc/ssl/influxdb.pem"

  # The SSL private key to use when HTTPS is enabled.
  https-private-key = ""

  # The JWT auth shared secret to validate tokens against.
  shared-secret = ""

  # Determines whether the pprof endpoint is enabled.
  pprof-enabled = false

  # The max number of concurrent HTTP connections that may be open at once. If
  # this limit is exceeded, incoming connections may be dropped.
  max-concurrent-connections = 0

  # The maximum request body size that the HTTP server will accept.
  max-body-size = 0

  # Whether the server should log the response time for requests.
  log-enabled = true

  # The port used by the HTTP service.
  port = ":8888"

3. 保存配置文件

修改完成后，保存配置文件即可。在 Linux 系统中，使用如下命令重启 InfluxDB：

sudo systemctl restart influxdb

在 Windows 系统中，重新启动 InfluxDB 服务即可。
