Some days ago my pal @masolino discovered and linked me this project on Github: mas-cli which is a command line interface to Apple’s macOS App Store …
A project like this is clearly aimed at every business environment where a sysadmin can use scripts to install, upgrade or remove the licensed software on their machines.
Even if this kind of market seems “abandoned” by Apple, the reality is that reports of successfully Mac integration in business and enterprise environments grow every month so this kind of utility is going to be appreciated by the most skilled sysadmins … and, anyway, a super interesting one!
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.
At work we’re in the middle of the development of a new Tomcat powered bioinformatics application, and have reached the stage were you have to show it to some peers but not make it publicly available. I do have an ubuntu 12.04 LTS server, so I took the most out of this Randeep’s post:
password protected directory in Tomcat →
Here it is how to do it in few steps:
- Add user, password and role in conf/tomcat-users.xml
- In the webapps/examples/WEB-INF/web.xml specify role, method and urls.
- Restart Tomcat and check the result
In these days I’m participating in the RECAS School of Cloud Computing by the Physics Faculty of University & Politecnico of Bari, and our teachers are showing us some technologies involved in their cloud infrastructure.
Zabbix is a monitoring solution deployed here, and illustrated to us by Vincenzo Spinoso, that has replaced old-school solutions like Nagios, Munin and such that caught my eye. I liked it so much, the documentations is so rich, I think I’ll dump my Munin installations and migrate everything to it ASAP when I’ll get back at the office…
