Serve the remote over HTTP.
rclone serve http implements a basic web server to serve the remote over HTTP. This can be viewed in a web browser or you can make a remote of type http read from it.
You can use the filter flags (eg --include, --exclude) to control what is served.
The server will log errors. Use -v to see access logs.
--bwlimit will be respected for file transfers. Use --stats to control the stats printing.
Use --addr to specify which IP address and port the server should listen on, eg --addr 18.104.22.168:8000 or --addr :8080 to listen to all IPs. By default it only listens on localhost. You can use port :0 to let the OS choose an available port.
If you set --addr to listen on a public or LAN accessible IP address then using Authentication is advised - see the next section for info.
--server-read-timeout and --server-write-timeout can be used to control the timeouts on the server. Note that this is the total time for a transfer.
--max-header-bytes controls the maximum number of bytes the server will accept in the HTTP header.
--baseurl controls the URL prefix that rclone serves from. By default rclone will serve from the root. If you used --baseurl “/rclone” then rclone would serve from a URL starting with “/rclone/”. This is useful if you wish to proxy rclone serve. Rclone automatically inserts leading and trailing “/” on --baseurl, so --baseurl “rclone”, --baseurl “/rclone” and --baseurl “/rclone/” are all treated identically.
By default this will serve files without needing a login.
You can either use an htpasswd file which can take lots of users, or set a single username and password with the --user and --pass flags.
Use --htpasswd /path/to/htpasswd to provide an htpasswd file. This is in standard apache format and supports MD5, SHA1 and BCrypt for basic authentication. Bcrypt is recommended.
To create an htpasswd file:
touch htpasswd htpasswd -B htpasswd user htpasswd -B htpasswd anotherUser
The password file can be updated while rclone is running.
Use --realm to set the authentication realm.
By default this will serve over http. If you want you can serve over https. You will need to supply the --cert and --key flags. If you wish to do client side certificate validation then you will need to supply --client-ca also.
--cert should be a either a PEM encoded certificate or a concatenation of that with the CA certificate. --key should be the PEM encoded private key and --client-ca should be the PEM encoded client certificate authority certificate.
--dir-cache-time flag, you can set how long a
directory should be considered up to date and not refreshed from the
backend. Changes made locally in the mount may appear immediately or
invalidate the cache. However, changes done on the remote will only
be picked up once the cache expires if the backend configured does not
support polling for changes. If the backend supports polling, changes
will be picked up on within the polling interval.
Alternatively, you can send a
SIGHUP signal to rclone for
it to flush all directory caches, regardless of how old they are.
Assuming only one rclone instance is running, you can reset the cache
kill -SIGHUP $(pidof rclone)
If you configure rclone with a remote control then you can use rclone rc to flush the whole directory cache:
rclone rc vfs/forget
Or individual files or directories:
rclone rc vfs/forget file=path/to/file dir=path/to/dir
--buffer-size flag determines the amount of memory,
that will be used to buffer data in advance.
Each open file descriptor will try to keep the specified amount of data in memory at all times. The buffered data is bound to one file descriptor and won’t be shared between multiple open file descriptors of the same file.
This flag is a upper limit for the used memory per file descriptor.
The buffer will only use memory for data that is downloaded but not
not yet read. If the buffer is empty, only a small amount of memory
will be used.
The maximum memory used by rclone for buffering can be up to
--buffer-size * open files.
These flags control the VFS file caching options. The VFS layer is used by rclone mount to make a cloud storage system work more like a normal file system.
You’ll need to enable VFS caching if you want, for example, to read and write simultaneously to a file. See below for more details.
Note that the VFS cache works in addition to the cache backend and you may find that you need one or the other or both.
--cache-dir string Directory rclone will use for caching. --vfs-cache-max-age duration Max age of objects in the cache. (default 1h0m0s) --vfs-cache-mode string Cache mode off|minimal|writes|full (default "off") --vfs-cache-poll-interval duration Interval to poll the cache for stale objects. (default 1m0s) --vfs-cache-max-size int Max total size of objects in the cache. (default off)
If run with
-vv rclone will print the location of the file cache. The
files are stored in the user cache file area which is OS dependent but
can be controlled with
--cache-dir or setting the appropriate
The cache has 4 different modes selected by
The higher the cache mode the more compatible rclone becomes at the
cost of using disk space.
Note that files are written back to the remote only when they are closed so if rclone is quit or dies with open files then these won’t get written back to the remote. However they will still be in the on disk cache.
If using --vfs-cache-max-size note that the cache may exceed this size for two reasons. Firstly because it is only checked every --vfs-cache-poll-interval. Secondly because open files cannot be evicted from the cache.
In this mode the cache will read directly from the remote and write directly to the remote without caching anything on disk.
This will mean some operations are not possible
This is very similar to “off” except that files opened for read AND write will be buffered to disks. This means that files opened for write will be a lot more compatible, but uses the minimal disk space.
These operations are not possible
In this mode files opened for read only are still read directly from the remote, write only and read/write files are buffered to disk first.
This mode should support all normal file system operations.
If an upload fails it will be retried up to --low-level-retries times.
In this mode all reads and writes are buffered to and from disk. When a file is opened for read it will be downloaded in its entirety first.
This may be appropriate for your needs, or you may prefer to look at the cache backend which does a much more sophisticated job of caching, including caching directory hierarchies and chunks of files.
In this mode, unlike the others, when a file is written to the disk,
it will be kept on the disk after it is written to the remote. It
will be purged on a schedule according to
This mode should support all normal file system operations.
If an upload or download fails it will be retried up to --low-level-retries times.
Linux file systems are case-sensitive: two files can differ only by case, and the exact case must be used when opening a file.
Windows is not like most other operating systems supported by rclone. File systems in modern Windows are case-insensitive but case-preserving: although existing files can be opened using any case, the exact case used to create the file is preserved and available for programs to query. It is not allowed for two files in the same directory to differ only by case.
Usually file systems on MacOS are case-insensitive. It is possible to make MacOS file systems case-sensitive but that is not the default
The “--vfs-case-insensitive” mount flag controls how rclone handles these two cases. If its value is “false”, rclone passes file names to the mounted file system as is. If the flag is “true” (or appears without a value on command line), rclone may perform a “fixup” as explained below.
The user may specify a file name to open/delete/rename/etc with a case different than what is stored on mounted file system. If an argument refers to an existing file with exactly the same name, then the case of the existing file on the disk will be used. However, if a file name with exactly the same name is not found but a name differing only by case exists, rclone will transparently fixup the name. This fixup happens only when an existing file is requested. Case sensitivity of file names created anew by rclone is controlled by an underlying mounted file system.
Note that case sensitivity of the operating system running rclone (the target) may differ from case sensitivity of a file system mounted by rclone (the source). The flag controls whether “fixup” is performed to satisfy the target.
If the flag is not provided on command line, then its default value depends on the operating system where rclone runs: “true” on Windows and MacOS, “false” otherwise. If the flag is provided without a value, then it is “true”.
