  • How to create an RPM package – FedoraProject – This page describes in detail how to create an RPM package, and in particular, how to create a SPEC file. Unlike other RPM guides, this page explains the specifics for Fedora with links to Fedora-specific guidelines. Since it is maintained through the Fedora Wiki, it is likely to be more up-to-date than other guides. Despite the focus on Fedora, most of this document does apply to other RPM-based distributions.
  • How To Install Elasticsearch, Logstash, and Kibana 4 on CentOS 7 | DigitalOcean – In this tutorial, we will go over the installation of the Elasticsearch ELK Stack on CentOS 7—that is, Elasticsearch 1.4.4, Logstash 1.5.0, and Kibana 4. We will also show you how to configure it to gather and visualize the syslogs of your systems in a centralized location. Logstash is an open source tool for collecting, parsing, and storing logs for future use. Kibana 4 is a web interface that can be used to search and view the logs that Logstash has indexed. Both of these tools are based on Elasticsearch.

  • SIAMO GEEK – Sperimentatori, entusiasti della tecnologia | Rigenerare le chiavi ssh – Quanto è vecchia la vostra chiave ssh? Rigenerare le chiavi ssh usate per collegarsi ai server è una rottura di scatole, ma potrebbe essere una rottura di molte unità di grandezza inferiore rispetto allo scoprire che una chiave ssh viene usata da mesi a nostra insaputa. Quanto sono corte/lunghe le chiavi ssh registrate nei file authorized-keys dei vostri server? Per fortuna a questa ultima domanda c’è una risposta veloce sotto forma di un pratico script shell.
  • Downloading Java RPM from wget | Giuseppe Paternò – This is a very basic post, but I consider it for myself rather for public consumption. I needed to download the Java RPM from the Oracle website from command line, as I’m connected to my systems from a low bandwidth site. I needed to find the cookies that Oracle website uses for “accepting” Oracle license to use properly wget from command line.

  • jordansissel/fpm – Effing package management! Build packages for multiple platforms (deb, rpm, etc) with great ease and sanity.
  • Linux incrond inotify: Monitor Directories For Changes And Take Action – I want to copy (rsync to remote server) a directory tree whenever file uploaded or deleted in /var/www/html/upload/ directory under Linux operating systems for backup purpose and/or load balancing purpose without getting into complex file sharing setup such as NFS or GFS iscsi storage. How do I monitor /var/www/html/upload/ and its subdirectory for new files and executes rsync command to make copy back to inotify is an inode-based filesystem notification technology. It provides possibility to simply monitor various events on files in filesystems. It is a very much powerful replacement of (obsolete) dnotify. inotify brings a comfortable way how to manage files used in your applications. The incrond (inotify cron daemon) is a daemon which monitors filesystem events (such as add a new file, delete a file and so on) and executes commands or shell scripts. It’s use is generally similar to cron.
  • Use incron to Trigger Action when File Changes – There are some situations, when you need to start an action or run a command when a given file has changed in your file system. The real life example I have is as follows: I have a git repository, from where I manage this blog, I have a remote branch of it on the same server, from where Nginx serves this pages. I also have another remote branch in my Macbook Pro (With the correspondent Time Machine backup). But, I’m a paranoid guy, so I just want more backups. I decided I wanted to backup all my blog files to my Dropbox account.

  • Howto: Change the IP address of a Dell 4/P DRAC from the command line without rebooting the server – Normally you configure a Dell Remote Access Card (DRAC) when a server is initially commissioned. Once the card is set, administrators rarely if ever need to modify the settings. If you do need to change the settings, the server needs to be restarted so the DRAC BIOS can be modified, which obviously results in system downtime and requires a physical presence at the server console.
  • bash ini parser | /var/log/ajdiaz – In some situations i like to use INI files as configuration files, as python do. But bash do not provide a parser for these files, obviously you can use a awk code or a couple of sed calls, but if you are bash-priest and do not want to use nothing more, then you can try the following obscure code:
  • Jugg Monkey: VMWare HA Agent had an error – I recently had a problem with one hoste in a 3 node VMWare ESX 3. 5 cluster. For some reason, the HA Agent would not start after I applied outstanding software updates. I kept receiving "VMWare HA Agent had an error" in the alerts after the host came online. I had recently needed to change the IP address of the VMWare 3.5 ESX host, so I figured that was the root cause.
