使用配置文件 (AEN 4.1.3)#

每个组件的配置文件的默认位置是：

  • Server—/opt/wakari/wakari-server/etc/wakari/config.json.
  • Gateway—/opt/wakari/wakari-gateway/etc/wakari/config.json.
  • Compute—/opt/wakari/wakari-compute/etc/wakari/config.json.

此外，特定服务的配置文件也可能存在于以下位置：

  • Server—/opt/wakari/wakari-server/etc/wakari/wk-server-config.json.
  • Gateway—/opt/wakari/wakari-gateway/etc/wakari/wk-gateway-config.json.
  • Compute—/opt/wakari/wakari-compute/etc/wakari/wk-compute-config.json.

每个服务按以下顺序加载每个配置文件，并在每一步更新AEN配置：

  1. /etc/wakari/config.json.
  2. /etc/wakari/wk-gateway-config.json.
  3. /opt/wakari/wakari-SERVICE/etc/wakari/config.json.
  4. /opt/wakari/wakari-SERVICE/etc/wakari/wk-SERVICE-config.json.
  5. ./config.json.
  6. ./wk-gateway-config.json.

检查配置文件语法

要验证配置文件包含有效的JSON，请运行：

root@server  # python -m json.tool /opt/wakari/wakari-server/etc/wakari/*.json
root@gateway # python -m json.tool /opt/wakari/wakari-gateway/etc/wakari/*.json
root@compute # python -m json.tool /opt/wakari/wakari-compute/etc/wakari/*.json

如果文件正确，内容将显示出来。

如果文件中存在语法错误，则会显示“无法解码JSON对象”的消息。

要修复任何错误，请编辑配置文件并确保其包含正确的JSON语法。
