Hue 3.8.1 on centos 7 - How to start it

prakashpunj — Tue, 21 Apr 2026 11:32:20 GMT

I have installed Hue 3.8.1 from tarball and it's running on centos 7. I am not sure how to start hue.

Below is the directory structure.

[root@ds hue-3.8.1]# ls -l total 56 drwxrwxr-x. 21 sitadmin sitadmin 4096 May 4 2015 apps drwxr-xr-x. 3 root root 17 Mar 10 23:14 build drwxrwxr-x. 5 sitadmin sitadmin 58 May 4 2015 desktop drwxrwxr-x. 6 sitadmin sitadmin 142 May 4 2015 docs drwxrwxr-x. 3 sitadmin sitadmin 24 May 4 2015 ext -rw-rw-r--. 1 sitadmin sitadmin 11358 May 4 2015 LICENSE.txt -rw-rw-r--. 1 sitadmin sitadmin 4715 May 4 2015 Makefile -rw-rw-r--. 1 sitadmin sitadmin 8505 May 4 2015 Makefile.sdk -rw-rw-r--. 1 sitadmin sitadmin 3498 May 4 2015 Makefile.vars -rw-rw-r--. 1 sitadmin sitadmin 2192 May 4 2015 Makefile.vars.priv drwxrwxr-x. 2 sitadmin sitadmin 21 May 4 2015 maven -rw-rw-r--. 1 sitadmin sitadmin 801 May 4 2015 NOTICE.txt -rw-rw-r--. 1 sitadmin sitadmin 1562 May 4 2015 README drwxrwxr-x. 5 sitadmin sitadmin 89 May 4 2015 tools -rw-rw-r--. 1 sitadmin sitadmin 932 May 4 2015 VERSION

@prakashpunj

The hue-server package includes service scripts to start and stop the Hue Server.

To start the Hue Server:

$ sudo service hue start

To restart the Hue Server:

$ sudo service hue restart

To stop the Hue Server:

$ sudo service hue stop

Per documentation, the start command is:

/usr/local/hue/build/env/bin/supervisor

If it doesn't start, make sure you have completed the "make apps" command and installed all dependencies. Also depending on your system you want to chown -R hue:hue /usr/local/hue

I see supervisor.py file got created in different folder than /usr/local/hue. It's in desktop/core/src/desktop folder. I am running as root. Below is what I get

[root@ds desktop]# pwd /root/hue-3.8.1/desktop/core/src/desktop [root@ds desktop]# ./supervisor -bash: ./supervisor: No such file or directory [root@ds desktop]# ./supervisor.py -bash: ./supervisor.py: Permission denied [root@ds desktop]# chmod 777 supervisor.py [root@ds desktop]# ./supervisor.py Traceback (most recent call last): File "./supervisor.py", line 32, in <module> from daemon.pidlockfile import PIDLockFile ImportError: No module named daemon.pidlockfile

looks like you have it installed as /root/hue-3.8.1

try using /root/hue-3.8.1 instead of /usr/local/hue in the startup command?

I would recommend to put it in /usr/local and symlink if not installed as just /hue/ folder:

ln -s /usr/local/hue-3.8.1 /usr/local/hue

also make sure you execute "make apps" in the folder to install everything as the hue user...

I managed to install it (version 4.x) of hue on centos but when I hit it from the browser, here is what I get rather than a login screen.

This is what I see when I run the supervisor

OperationalError: attempt to write a readonly database

Need to fix the write perms on the database file... not sure of the path you have now, but mine was in the desktop folder.

@stevenmatison

So what permission do I need to change to which file ?

I changed the permission to 777 to desktop.db which is under desktop folder but no help.

Thanks

@stevenmatison

So I changed Hue directory permission to hue user and that fixed the issue..
