Fedora Installation

Aggregate Installation Tips

One of the reasons I am writing this blog, is to keep “log” for myself on how I resolved issues.

In this post I will describe how I installed several basic development tools on a Fedora OS.
I want this laptop to be my workstation for out-of-work projects.

Almost everything in this post can be found elsewhere in the web.
Actually, most of what I am writing here is from other links.

However, this post is intended to aggregate several installations together.

If you’re new to Linux (or not an expert, as I am not), you can learn some basic stuff here.
How to install (yum), how to create from source code, how to setup environment variables and maybe other stuff.

First, we’ll start with how I installed Fedora.

Installing Fedora

I downloaded Fedora ISO from https://getfedora.org/en/workstation/.
It is Gnome distribution.
I then used http://www.linuxliveusb.com/ to create a self bootable USB. It’s very easy to use.
I switched to KDE by running: sudo yum install @kde-desktop

Installing Java

Download the rpm package Oracle site.

Under /etc/profile.d/ , create a file (jdk_home.sh) with the following content:

I used the following link, here’d how to install JDK

Installing Intellij

Location: https://www.jetbrains.com/idea/download/

Check https://www.jetbrains.com/idea/help/basics-and-installation.html

After installation, you can go to /opt/idea/latest/bin and run idea.sh
Once you run it, you will be prompt to create a desktop entry.
You can create a command line launcher later on as well.

Installing eclipse

Location: http://www.eclipse.org/downloads/

Create executable /usr/bin/eclipse

Create Desktop Launcher

Installing Maven

Download https://maven.apache.org/download.cgi

Setting maven environment

Installing git

I wanted to have the latest git client.
Using yum install did not make it, so I decided to install from source code.
I found a great blog explaining how to do it.
http://tecadmin.net/install-git-2-0-on-centos-rhel-fedora/
Note: in the compile part, he uses export to /etc/bashrc .
Don’t do it. Instead create a file under /etc/profile.d
Installation commands

git Environment
Create an ‘sh’ file under /etc/profile.d

PostgreSQL on Fedora

I bought (and started reading) the book Seven Databases in Seven Weeks in order to have better understanding of the different SQL / NoSQL paradigms. What are the pros and cons of each approach and play around with each type.

In this post I want to share the installation process I had with PostgreSQL on Fedora.
I will write a different post about the book itelf.

The Installation
I don’t know why, but installing PostgreSQL on the Fedora wasn’t as easy as expected.
It took me several tries to make it work.

I went over and over on the tutorials, read posts and questions with the same problems I had.
Eventually I made it work. I am not sure whether this is the correct way, but it’s good enough for me to work on it.

The Errors
During my attempts, I got some errors.

The most annoying one, was:

psql: could not connect to server: No such file or directory
 Is the server running locally and accepting
 connections on Unix domain socket "/var/lib/pgsql/.s.PGSQL.5432"?

I also got

FATAL:  could not create lock file "/var/run/postgresql/.s.PGSQL.5432.lock": Permission denied

Sometimes I got port 5432 already in use.

Took some time, but I managed to install it
I am not entirely sure how I made it work, but I’ll post here the actions I did.
(for my future self of-course).

Installation Instructions: http://www.postgresql.org/download/linux/redhat/

# install postgresql on the machine
sudo yum install postgresql-server

# fill the data directory (AKA init-db)
# REMEMBER - here it is: /var/lib/pgsql/data/
sudo postgresql-setup initdb

# Enable postgresql to be started on bootup:
# (I hope it works...)
sudo systemctl enable postgresql.service

The next steps were to run the service, login, create DB and start playing.
This was the part where I kept getting the errors describes above.

First step was to login as postgres user, which is created during installation.
You can’t start the server as sudo.
As I am (still) not a Linux expert, I had to figure out that w/o password for postgres, I’ll need to su from the root.

# Login
sudo -s
# password for root...

# switch to postgres
su - postgres

The next step was to start the service.
That was the painful issue. Although very satisfying after success.
After careful looking at the error message and some Googling, I decided to add the -D to the commands.
I didn’t try it before, as I thought it wasn’t necessary because I added PGDATA.
Eventually I am not using it.

So this is the command that worked for me:

pg_ctl start -D /var/lib/pgsql/data/

And now what…?

In my first attempts, whenever I tried to run a PG command (psql, createdb), I got the annoying error described above.
But now it worked !

As postgres user, I ran psql and I was logged in.
After that I could start working on the book.

Some Tips

  • Don’t forget to add semi-colon at the end of the commands 🙂
  • create extension tablefunc;
    create extension dict_xsyn;
    create extension fuzzystrmatch;
    create extension pg_trgm;
    create extension cube;
    
  • I didn’t have to modify any configuration file (I.e. pg_hba.conf).
  • README file /usr/share/doc/postgresql/README.rpm-dist
  • co

    Disclaimer
    This post was made out of notes that I wrote to myself during the hard installation.
    I am sure this is not the best (or maybe it is?)

    In the following posts I will share the reading progress of the book.

    I added a GitHub project with code I’m writing while reading the book.

    (EDIT – I wrote this post at 2 AM, so I hoope there aren’t any major mistakes)

    Installing Fedora and Solving a Wifi Issue

    I am writing this post as a future reminder for myself.

    I decided to install a Linux OS on an old laptop. And I didn’t want a Debian system (I am using Ubuntu at the office). So I went to Fedora. I just want to get my hands more dirty on Linux.

    For installation I used Linux Live USB Creator

    I picked up the latest Fedora installation (V. 20 with KDE) and installed it in my USB.

    After that I rebooted my laptop with the USB and installed the OS. Really simple I must say.

    The problem now was that the OS could not see the wireless card.

    The laptop is Dell Inspiron. The wifi card is Broadcom.

    In order to check which wifi card run either one of:

    • lspci
    • lspci | grep -i Network

    So here’s what I needed to do:

    1. Install Fusion RPM, free and nonfree from http://rpmfusion.org/Configuration
    2. Run the following command su -c ‘yum install broadcom-wl’
    3. Reboot

    And I had Fedora KDE V20 with Wifi !

    A small note about centOS, I tried install it before but just could not fix the Wifi issue.
