Install Phalcon PHP framework in Fedora

In my last article i discussed that how to install phalcon framework in openSUSE, and i guess it was quite fun and easy. Today i am extending the installation to Fedora. I installed it on Fedora 19, 20 and i hope there would be no problems for anyone, it will be quite simple and easy to install. As we know, we don’t have any repo or RPM at the moment for Fedora, so we will build it from source. Don’t worry it will not be scary. Read this for the dependencies 1st.

Fire up the terminal and i assume that you are in your home dir ([user@localhost ~]$). But no worries, you can change the dir to any where you want like your backup drive etc. Let’s go with home in this article. We need to clone the phalcon repository from github and create the extension from source.

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”3″ tab_size=”4″]
[user@localhost ~]$ git clone git://github.com/phalcon/cphalcon.git
[user@localhost ~]$ cd cphalcon/build
[user@localhost ~]$ sudo ./install
[/cc]

That will do the necessary for now, one last thing now. Open php.ini in terminal or whatever GUI editor you prefer(i will use vim):

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”1″ tab_size=”4″]
[user@localhost ~]$ sudo vim /etc/php.ini
[/cc]

And add this line:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”1″ tab_size=”4″]
extension=phalcon.so
[/cc]

Save and that’s it. Time to restart the server:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”1″ tab_size=”4″]
[user@localhost ~]$ sudo service httpd restart
[/cc]

Download any of the app from the phalcon repo like invo OR vokuro etc, and give it a try.

Enjoy!

Install Phalcon PHP framework in openSUSE

Phalcon is a web framework implemented as a C extension offering high performance and lower resource consumption”. From the benchmark page, “The compiled nature of Phalcon offers extraordinary performance that outperforms all other frameworks measured in these benchmarks”. Personally i find it very easy to work with, less dirs and files for the project. And it’s documentation is quite organized and useful. Installation in Linux distros is quite easy for most of the parts. Let’s install in openSUSE 12.3 and 13.1. 1st of all let’s thank Mariusz Łączak for his useful work to provide repositories. Fire up a terminal and become root by su – .

If you are on openSUSE 12.3, add this repo:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper ar -f http://download.opensuse.org/repositories/home:/mruz/openSUSE_12.3/ Phalcon

[/cc]

For openSUSE 13.1:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper ar -f http://download.opensuse.org/repositories/home:/mruz/openSUSE_13.1/ Phalcon

[/cc]

zypper-add-repo-phalcon

Refresh the repos:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper ref

[/cc]

It will ask for the key to trust for the new repo, just type a to trust always. We are almost there.

Before installation of phalcon, we need to make sure that these dependencies are installed: mbstring, mcrypt, opensll, pdo/MySQL

If not, no worries install it by using this command:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper in php5-mbstring mcrypt openssl php5-pdo

[/cc]

Time to install phalcon:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper in php5-phalcon

[/cc]

And that’s it, but before jumping to your web dir to start a demo project, restart apache:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

systemctl restart apache2.service

[/cc]

Phalcon documentation are self explanatory and easy to follow. Start here for a test project.

Install Nodejs in openSUSE 12.3

Nodejs is quite in news now a days and for good. Let’s not go to details here, straight to install process and get it working. The 1st thing is to fire a terminal and become root by su – . Let’s add a repository for the latest Nodejs packages, default openSUSE repos have Nodejs but old version (.8.12):

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper ar -f http://download.opensuse.org/repositories/home:/kwk:/orientdb/openSUSE_12.3/ Nodejs

[/cc]

After that refresh the repos:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

zypper ref

[/cc]

And now installation time:

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”4″ tab_size=”4″]

zypper install nodejs nodejs-devel

[/cc]

Latest Nodejs has npm packaged with it, so we should be good by installing Nodejs package.

And that should be it for now, keep checking i will write about how to use it and install some plugins, framework to work with.

32bit arch:

How to install chromium browser in fedora 19

To install chromium browser in fedora you need to add a repo file to the yum.repos.d dir as it is not available in rpm fusion repos. So download the repo file from the link below:

https://repos.fedorapeople.org/repos/spot/

Right click on the fedora-chromium-stable.repo and save it to you hard drive by selecting “Save Link As”.

Now open terminal and cd to the location/dir where you downloaded the file. After that run this command:

sudo cp fedora-chromium-stable.repo /etc/yum.repos.d

And now time to install it:

sudo yum -y install chromium

And that’s it.

 

Split and Join file in Linux via terminal

Have ever want to split a big file or may be a normal file into multiple parts and later join them. Well, in Linux i would say that is quite easy by using split and cat commands in terminal.

Let’s try it with an example. Open terminal. If you want to read more, the easy way is the Linux man pages. Just type this, and you will get all the help related to split command. Same goes for other commands too.

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

split –help

[/cc]

split-help

Let’s say i have a file V-for-vendetta.mkv size of 367 MB in location /backup/Downloads/V-for-Vendetta/. 1st of i want to split this file into 100 MB each part.

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”4″ tab_size=”4″]

cd /backup/Downloads/V-for-Vendetta

split -b100M V-for-Vendetta.mkv vendetta.mkv

[/cc]

M represents megabytes, K represents kilobytes and B represents bytes. Even can use G for gigabytes and T for terabytes etc. Read help of split for more.

The 1st is the name of the original file (V-for-Vendetta.mkv) and the second one is the new file name. It will split it into 4 parts like vendetta.mkvaa, vendetta.mkvab, vendetta.mkvac, vendetta.mkvad.

slipt-file

split-results

Check the images for the commands and results.

Now is time to merge all the parts into one file again.

[cc lang=”bash” escaped=”true” nowrap=”false” noborder=”true” line_numbers=”false” lines=”2″ tab_size=”4″]

cat vendetta.mkv* > vendetta.mkv

[/cc]

Cat command will do the bits here, nothing fancy here to explain, its self explanatory. Read more about cat from man pages in terminal. Just note the * here, as we removed the aa, ab, ac, ad etc from the original parts name.

join-file-with-cat

after-join-file-with-cat

And that’s it.

Happy splitting and joining.
