Deploy Alluxio Locally
This guide goes over how to run and test Alluxio on your local machine.
- Mount RAMFS file system
- Format Alluxio Filesystem
- Start Alluxio Filesystem Locally
- Verify Alluxio is running
The prerequisite for this part is that you have Java (JDK 8 or above) installed.
Download the binary distribution of Alluxio 2.1.0
To run in standalone mode, do the following:
You should have received an email from your Alluxio sales representative which includes your Alluxio Enterprise Edition license. Download the attached license, rename the file to
license.json, and place it in the root of the extracted binary.
conf/alluxio-site.propertiesto a tmp directory in the local filesystem (e.g.,
Turn on remote login service so that
ssh localhostcan succeed. To avoid the need to repeatedly input the password, you can add the public SSH key for the host into
~/.ssh/authorized_keys. See this tutorial for more details.
Mount RAMFS file system
Run the below command to mount RAMFS file system.
$ ./bin/alluxio-mount.sh SudoMount
Format Alluxio Filesystem
NOTE: This step is only required when you run Alluxio for the first time. If you run this command for an existing Alluxio cluster, all previously stored data and metadata in Alluxio filesystem will be erased. However, data in under storage will not be changed.
$ ./bin/alluxio format
Start Alluxio Filesystem Locally
Simply run the following command to start Alluxio filesystem.
# If you have not mounted the ramdisk or want to remount it (ie. to change the size) $ ./bin/alluxio-start.sh local SudoMount # OR if you have already mounted the ramdisk $ ./bin/alluxio-start.sh local
NOTE: On Linux, this command may require to input password to get sudo privileges in order to setup RAMFS. If you do not want to type in the password every time, or you do not even have sudo privileges, please read the alternative approaches in FAQ.
Verify Alluxio is running
To verify that Alluxio is running, you can visit
http://localhost:19999, or see the log in the
To run a more comprehensive sanity check:
$ ./bin/alluxio runTests
You can stop Alluxio any time by running:
$ ./bin/alluxio-stop.sh local
Why is sudo privilege needed to start Alluxio on Linux?
By default, Alluxio filesystem uses RAMFS as its in-memory data storage. On MacOS, it is fine for Alluxio to mount a RAMFS without being a super user. However, on Linux, it requires sudo privileges to perform “mount” (and the followed “umount”, “mkdir” and “chmod” operations).
Can I still try Alluxio on Linux without sudo privileges?
If you have no sudo privileges on Linux, for Alluxio Filesystem to work, it requires a RAMFS (e.g.,
/path/to/ramdisk) already mounted
by the system admin and accessible for read/write-operations by the user. In this case you have can specify the path in
and then start Alluxio with
NoMount option to use the above directory as its data storage:
$ ./bin/alluxio-start.sh local NoMount
Alternatively, you can also specify Linux tmpFS
as the data storage. Tmpfs is a temporary file storage backed by memory (e.g., typically
/dev/shm on Linux), but may use SWAP space and
therefore provides less performance guarantees compared to ramfs. Similar to using a pre-mounted RAMFS, you can specify the tempfs path in
$ ./bin/alluxio-start.sh local NoMount
How can I avoid typing the password to run sudo?
- Start Alluxio as a super user.
- Add the user to start Alluxio in sudoers.
- Give limited sudo privileges to the running user (e.g., “alluxio”) by adding the following line to
alluxio ALL=(ALL) NOPASSWD: /bin/mount * /mnt/ramdisk, /bin/umount */mnt/ramdisk, /bin/mkdir * /mnt/ramdisk, /bin/chmod * /mnt/ramdisk
This allows Linux user “alluxio” to mount, umount, mkdir and chmod (assume they are in
/mnt/ramdisk with sudo privileges without typing the password, but nothing else. See
