Configurations¶

This document gives some introduction to configurations in Nebula Graph.

For the path and usage of local configuration files for Nebula Graph services, see:

• Meta configuration
• Graph configuration
• Storage configuration

Get configurations¶

Most configurations are gflags. You can get all the gflags and the explanations by the following command.

<binary> --help

For example:

$ ./nebula-metad  --help
$ ./nebula-graphd --help
$ ./nebula-storaged --help
$ ./nebula-console --help

Besides, you can get the values of running flags by curl-ing from the services.

For example:

$ curl 127.0.0.1:19559/flags # From Meta
$ curl 127.0.0.1:19669/flags # From Graph
$ curl 127.0.0.1:19779/flags # From Storage

Modify configurations¶

We suggest that you change configurations from local configure files. To change configurations from local files, follow these steps:

1. Add --local_config=true to each configuration file. The configuration files are stored in /usr/local/nebula/etc/ by default. If you have customized your Nebula Graph installation directory, the path to your configuration files is $pwd/nebula/etc/.
2. Save your modification to the files.
3. Restart the Nebula Graph services.

NOTE: Remember to add --local_config=true to each configuration file. To make your modifications take effect, restart all the Nebula Graph services.

Legacy version compatibility¶

The curl commands and parameters in Nebula Graph v2.x. are different from Nebula Graph v1.x. Those curl commands in v1.x are deprecated now.
