Hue 3.8.1 on centos 7 - How to start it

[#1]

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.

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

[#3 · Accepted solution]

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

[#4]

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

[#5]

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...

[#6]

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.

[#8]

@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..
