The following table lists the current requirements for running the Nuxeo Platform from the Tomcat server ZIP archive.
If you have requirements and/or constraints are not reflected below, do not hesitate to contact the Nuxeo team to evaluate the feasibility of running Nuxeo on any other environment.
||Note: the only limitation on OS nature and version is the ability to install the correct version of the required JDK (see below). It means that while it is commonly reported to run on recent versions of Ubuntu, RHEL, Debian, CentOS, it can also run on any Linux distribution where it is possible to install the required JDK. You may have to adapt the provided startup shell scripts.|
|Java||JDK 11 (Azul's Zulu OpenJDK or Oracle's JDK)||See the following documentation:|
|Optional Third-Party Software||Some third party software may be required depending on the conversions capabilities you want to benefit from. The following list is not exhaustive:

To check that you have the right version of Java:
Open a terminal:
- On Linux or macOS: open a terminal.
- On Windows: press the "Windows" key + r, type
command) in the Run window and press "OK" (or open the Command Prompt from Start > Programs > Accessories in Windows 7 or entering Command Prompt in Cortana in Windows 10)
java -versionand press Enter. If Java is correctly installed on your computer, the name and version of your Java virtual machine is displayed:
openjdk version "11.0.8" 2020-07-14 LTS OpenJDK Runtime Environment Zulu11.41+23-CA (build 11.0.8+10-LTS) OpenJDK 64-Bit Server VM Zulu11.41+23-CA (build 11.0.8+10-LTS, mixed mode)
Check in the output that the JDK version is 64 bits.
If Java is not installed on you computer, it will fail to display the Java version. In this case, install Java (see below).
If Java is installed but not included in the PATH, it will fail to find the Java command. In that case, you need to add
$JAVA_HOME/bin/to your PATH (see How do I set or change the PATH system variable?).
To ensure you installed a Java Development Kit environment, type
javac -versionand press Enter.
If you installed a JDK, the javac version is displayed:
If you installed a Java Runtime Environment instead of a Java Development Kit, it will fail to find javac and to display the javac version. In this case, install a Java Development Kit (see below).
Java packages and instructions for installation are available from the Azul website:
As for any software, we very strongly recommend upgrading to the latest bugfix version of the JDK for any given major version
Download the ZIP archive from the Nuxeo distribution download site and unzip it using your favorite tool.
The usual directory into which install the server is
Like any Java application you should prevent the JVM Heap from being swapped to disk, which will crush server performance. You have two options here:
- Disable the swap with
sudo swapoff -ayou'll need to edit your
/etc/fstabto disable swap permanently. Note that before doing this you need to make sure that you have enough memory for all the processes that run on the server (Nuxeo JVM, converters, other custom process and the OS).
- Limit the swapiness of the OS using
nuxeo.tmp.dir property in nuxeo.conf, we recommend not to use the system temporary folder
/tmp because this one can be cleaned up by the operating system. This is the case on Red Hat Enterprise Linux in particular, where
systemd-tmpfiles service is deleting old files from
Do not use the Windows built-in ZIP functionality (aka "zipfldr.dll" or "Compressed Folders Module"), it reports incorrect uncompressed size. Recommended: 7-Zip.
On Windows in general, and especially on Windows 7 or later versions, it is highly recommended to install your Nuxeo application at the root of a disk (
C:\Nuxeo for instance), because of rights issues, limitations on paths length, 32/64 bits conflicts,...
