Linux Cheatsheet

With everything going on with logicoma, I will be frequently updating this page so I can just jump back into whatever system tasks at hand. I should add this I'm going to keep this focused on ubuntu/debian. http://www.yolinux.com/TUTORIALS/LinuxTutorialAdditionalHardDrive.htmlhttp://www.cyberciti.biz/faq/linux-viewing-drive-partitions-with-fdisk-parted/X11 Forwarding using Putty on Windows - YouTubeStoragehttp://tldp.org/LDP/lame/LAME/linux-admin-made-easy/checking-storage-space.htmlhttps://www.cyberciti.biz/faq/linux-check-memory-usage Commandsfdisk -l mkdir ← a directoy of where to mount the disk mount ← mount a disk using /dev/[disk]

Running Solr on Google Cloud

Google App Engine has gone under a great number of changes and originally I set out to use it to my advantage but instead went through Google's cloud platform to run solr on a virtual machine. This gave me a lot more flexibility and didn't require to change any of Solr's source code. In theory changing the source code to handle the file system available through app engine would work.
      I'm not going to get into the steps of how I did this, I think it's pretty straight forward, setup your linux vm and install java, then set up tomcat with Solr. With my catalog-demo, I used the site to proxy to the vm and gave the vm permission to only my web site's IP. The links below are docs that give more information on that. As far as costs go, it is very cheap to spin up a machine and to get the Solr server running. However I'm not happy with the solution and know I can create an even better solution so I've shutdown the server and started looking at other …

LPI Certification Material

At one time I really wanted to take the LPI certification but I feel my experience speaks for itself. However I do want to cover the material and refresh myself on some of the stuff that I don't use on a regular basis. I bolded the commands I use the least and reworded the description a little more to my liking. Most of the information is just examples I found and stuff I think would be covered. Commands declare - Use the declare command to set variable and functions attributes.quota - displays users' disk usage and limits. By default only the user quotas are printed.date  - display or set the time.rpm- package manager. (I prefer debian)xvidtune - tweaks the screen resolution.nl - prints line numbers before each line in a file.od  -dumps files in octal format.su - option m is pretty useful, do not reset environment variables.mkfs - “used to build a Linux file system on a device, usually a hard disk partition.”XF86Config-the section concerned with fonts: The Files sectionsXF…

Sunyit's Project BITS Documentations

Image
The following is a collection of documents that I created solely for myself and colleagues in order to meet standards for implementing a Hadoop cloud service. That said there is a lot of information that is specific for the systems used and customized to only work for those who were apart the project. The objective for Project "Bits" can be found here in this link. All ip addresses have been marked with x's and urls generalized in order to protect the SunyIT network system. I continue to study the systems used here and release the documents in hope that others might take up the project and implement it at his or her's University/College.
