Lately I had to reconfigure an Ubuntu 14.04 server.
Dealing with Tomcat 7 I’ve encountered those two situations:
Enable larger file uploads via Tomcat manager
I had a ~180 war file to deploy. Ubuntu’s Tomcat setting put a limit at 50MB. This has been solved using the tips in this post by skotfred. Unfortunately I haven’t found a more orthodox way of achieving this other than modify the /usr/share/tomcat7-admin/manager/WEB-INF/web.xml in the values max-file-size and max-request-size.
Enable Tomcat monitoring in Munin
Here I’ve followed the tips over this Serverfault discussions.
Adding a [tomcat_ *] was the key.
The other day, after a do-release-update on an Ubuntu box I had some issues with a package which told me:
Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)
here’s how I solved:
mv /var/lib/dpkg/info/BROKEN-PACKAGE.* /tmp/
dpkg --remove --force-remove-reinstreq BROKEN-PACKAGE
Sometimes I find myself in the situation of having to lauch some graphical software like synaptic, gedit, baobab while already using the server as root from the command line. I do not want to ‘exit’ my session and use the previous methods of which I’ve written in the past.
This is how I did it.
koolinus@localhost:~$ ssh -Y email@example.com
koolinus@remote:~$ sudo -i
root@remote:~# touch .Xauthority
root@remote:~# xauth merge /home/koolinus/.Xauthority
And that’s all. Now I can launch the needed program without interrupting my root session, for example:
root@remote:~# baobab &
