Xwiki.start from snap wont work

cbouchet · July 11, 2023, 6:36am

Hi evreyone,

I installed recently xwiki on Red Hat via snap, but when i do “sudo xwiki.start”, I have this message

[root@srv-xwiki-test ~]# sudo xwiki.startup
sudo: xwiki.startup : command unknown

What did I do wrong ?

Here is the list of the command I made

sudo yum install snapd
sudo systemctl enable --now snapd.socket
sudo ln -s /var/lib/snapd/snap /snap
sudo snap install xwiki
sudo xwiki.start

I’ve followed those instructions from here :

https://dev.xwiki.org/xwiki/bin/view/GoogleSummerOfCode/XWiki%20Snap%20Guide/#HToStartXWiki and

When I go in the folder /var/snap/xwiki/current/ and start xwiki with " sh start_xwiki.sh", it works, but it’s not the good way.

Thank you for your help

Best regards

Maybe you have an idea @Pol.

Pol · July 11, 2023, 8:25am

hey @cbouchet ,
The command for starting the xwiki snap is

sudo xwiki.start

you seemed to have used xwiki.startup

cbouchet · July 11, 2023, 9:06am

Oh yes, sorry ! I copied the wrong command, but this command doesn’t work too

Pol · July 11, 2023, 11:59am

can you paste the output of the following command

snap list --all

cbouchet · July 11, 2023, 12:22pm

Sure, here :

[root@srv-xwiki-test current]# snap list --all

cbouchet · July 31, 2023, 6:07am

Hi Pol,

Sorry for my late answer. Do you have an idea of where the problem could be ?

Regards,

Pol · July 31, 2023, 8:05am

hey @cbouchet ,
sorry totally forgot about your question.
But it seems like its a problem with your environment variables

can you paste the output of your env

env

also, try installing and running the hello-world snap. To see if there is a problem with all the snap or XWiki snap in particular : )

Hello @cbouchet,

The snap appears to be functioning properly on Debian-based distributions.

The issue seems to be related to Red Hat security (SELinux). You have two options to resolve it:

I advise against this option, but you can disable SELinux on Red Hat by following this guide. Afterward, you should reinstall snapd and xwiki.snap.
Alternatively, you can solve the problem by adding /var/snap/xwiki/current/ to your PATH and executing sh start_xwiki.sh whenever you wish to run the Xwiki snap.

I will continue investigating this matter until then.

cbouchet · July 31, 2023, 9:21am

Thank you, I will look for this.

I tried, this morning, to run xwiki with the following command, but I had a different message

And it still did’nt work. Maybe I should reinstall it from scracth and see if I’ve the same problem…
I’ll try to reinstall snapd first and wiki, and I’ll do from scracth if it’s the same.

I’ll tell you
Thanks again

cbouchet · August 1, 2023, 9:17am

Hi,

I’ve reinstalled snapd and xwiki.
xwiki.start works but not with sudo.
Also, when xwiki starts, it start like a demo version. So when I close my ssh connexion, xwiki stop.

Is it “normal” ? Must I configure something ?

Thank you again

cbouchet · April 11, 2024, 1:11pm

I made a new server and installed it on Ubuntu making the simple command

sudo apt install xwiki-tomcat9-mysql

Everything works fine now.
