go-ipfs environment variables

LIBP2P_TCP_REUSEPORT (IPFS_REUSEPORT)

go-ipfs tries to reuse the same source port for all connections to improve NAT traversal. If this is an issue, you can disable it by setting LIBP2P_TCP_REUSEPORT to false.

This variable was previously IPFS_REUSEPORT.

Default: true

IPFS_PATH

Sets the location of the IPFS repo (where the config, blocks, etc. are stored).

Default: ~/.ipfs

IPFS_LOGGING

Sets the log level for go-ipfs. It can be set to one of:

  • CRITICAL
  • ERROR
  • WARNING
  • NOTICE
  • INFO
  • DEBUG

Logging can also be configured (on a subsystem by subsystem basis) at runtime with the ipfs log command.

Default: ERROR

IPFS_LOGGING_FMT

Sets the log message format. Can be one of:

  • color
  • nocolor

Default: color

GOLOG_FILE

Sets the file to which go-ipfs logs. By default, go-ipfs logs to standard error.

GOLOG_TRACING_FILE

Sets the file to which go-ipfs sends tracing events. By default, tracing is disabled.

This log can be read at runtime (without writing it to a file) using the ipfs log tail command.

Warning: Enabling tracing will likely affect performance.

IPFS_FUSE_DEBUG

Enables fuse debug logging.

Default: false

YAMUX_DEBUG

Enables debug logging for the yamux stream muxer.

Default: false

IPFS_FD_MAX

Sets the file descriptor limit for go-ipfs. If go-ipfs fails to set the file descriptor limit, it will log an error.

Defaults: 2048

IPFS_DIST_PATH

URL from which go-ipfs fetches repo migrations (when the daemon is launched with the --migrate flag).

Default: https://ipfs.io/ipfs/$something (depends on the IPFS version)

LIBP2P_MUX_PREFS

Tells go-ipfs which multiplexers to use in which order.

Default: "/yamux/1.0.0 /mplex/6.7.0"
