## Requirements
|
||||
|
||||
- Go 1.13 or higher as build only dependency.
|
||||
- Go 1.14 or higher as build only dependency.
|
||||
- A suitable SQL server to use as data provider: PostgreSQL 9.4+ or MySQL 5.6+ or SQLite 3.x.
|
||||
- The SQL server is optional: you can choose to use an embedded bolt database as key/value store or an in memory data provider.

@ -26,18 +26,23 @@ The `serve` command supports the following flags:
|
|||
|
||||
- `--config-dir` string. Location of the config dir. This directory should contain the configuration file and is used as the base directory for any files that use a relative path (eg. the private keys for the SFTP server, the SQLite or bblot database if you use SQLite or bbolt as data provider). The default value is "." or the value of `SFTPGO_CONFIG_DIR` environment variable.
|
||||
- `--config-file` string. Name of the configuration file. It must be the name of a file stored in `config-dir`, not the absolute path to the configuration file. The specified file name must have no extension because we automatically append JSON, YAML, TOML, HCL and Java extensions when we search for the file. The default value is "sftpgo" (and therefore `sftpgo.json`, `sftpgo.yaml` and so on are searched) or the value of `SFTPGO_CONFIG_FILE` environment variable.
|
||||
- `--loaddata-from` string. Load users and folders from this file. The file must be specified as absolute path and it must contain a backup obtained using the `dumpdata` REST API or compatible content. The default value is empty or the value of `SFTPGO_LOADDATA_FROM` environment variable.
|
||||
- `--loaddata-clean` boolean. Determine if the loaddata-from file should be removed after a successful load. Default `false` or the value of `SFTPGO_LOADDATA_CLEAN` environment variable (1 or `true`, 0 or `false`).
|
||||
- `--loaddata-mode`, integer. Restore mode for data to load. 0 means new users are added, existing users are updated. 1 means new users are added, existing users are not modified. Default 1 or the value of `SFTPGO_LOADDATA_MODE` environment variable.
|
||||
- `--loaddata-scan`, integer. Quota scan mode after data load. 0 means no quota scan. 1 means quota scan. 2 means scan quota if the user has quota restrictions. Default 0 or the value of `SFTPGO_LOADDATA_QUOTA_SCAN` environment variable.
|
||||
- `--log-compress` boolean. Determine if the rotated log files should be compressed using gzip. Default `false` or the value of `SFTPGO_LOG_COMPRESS` environment variable (1 or `true`, 0 or `false`). It is unused if `log-file-path` is empty.
|
||||
- `--log-file-path` string. Location for the log file, default "sftpgo.log" or the value of `SFTPGO_LOG_FILE_PATH` environment variable. Leave empty to write logs to the standard error.
|
||||
- `--log-max-age` int. Maximum number of days to retain old log files. Default 28 or the value of `SFTPGO_LOG_MAX_AGE` environment variable. It is unused if `log-file-path` is empty.
|
||||
- `--log-max-backups` int. Maximum number of old log files to retain. Default 5 or the value of `SFTPGO_LOG_MAX_BACKUPS` environment variable. It is unused if `log-file-path` is empty.
|
||||
- `--log-max-size` int. Maximum size in megabytes of the log file before it gets rotated. Default 10 or the value of `SFTPGO_LOG_MAX_SIZE` environment variable. It is unused if `log-file-path` is empty.
|
||||
- `--log-verbose` boolean. Enable verbose logs. Default `true` or the value of `SFTPGO_LOG_VERBOSE` environment variable (1 or `true`, 0 or `false`).
|
||||
- `--profiler` boolean. Enable the built-in profiler. The profiler will be accessible via HTTP/HTTPS using the base URL "/debug/pprof/". Default `false` or the value of `SFTPGO_PROFILER` environment variable (1 or `true`, 0 or `false`).

If you don't configure any private host key, the daemon will use `id_rsa`, `id_ecdsa` and `id_ed25519` in the configuration directory. If these files don't exist, the daemon will attempt to autogenerate them (if the user that executes SFTPGo has write access to the `config-dir`). The server supports any private key format supported by [`crypto/ssh`](https://github.com/golang/crypto/blob/master/ssh/keys.go#L33).
