This tutorial will teach you how to use wget to download entire folder of remote server with recursively

example: recursively download all the files that are in the subfolder3 folder for the ftp

ftp://user:pass@www.yourdomain.com/folder1/subfolder1/subfolder2/subfolder3

Solution:

 wget -r -np -nc -nH --cut-dirs=4 ftp://user:pass@www.yourdomain.com/folder1/subfolder1/subfolder2/subfolder3

-r = mean recursive
-np = Do not ever ascend to the parent directory when retrieving recursively.
-nc = skip existing files
-nH = no save folder as host name
-cut-dirs = remove all the subfolder during save, just the content inside subfolder3 will be saved.

Hope that help

Its very annoying, when you trying to start the services, but the port is already in use. What to do? Kill it! So that you can start the services again.

lsof -w -n -i tcp:5080

then the process and pid will appear.

kill it by typing:

kill -9 

hope that help.

Howdy folks, in this article i will show you on how to install red5 as media streaming server, video live broadcast server. Why Red5? Because it is a free version of RTMP server that does the same thing as commercial version of streaming server such as FMS, Wowza, etc. Lets cut the crap here, lets proceed to installation.

Lets prepare the ingredient before Red5 installation.

1. Install Java

Red5 is developed using java, so you will need java installed on your mechine before you can run it. Lets use yum to install it.

yum -y install java-1.6.0-openjdk java-1.6.0-openjdk-devel

2. In order to compile red5 on your server, you will need a tool called ant. Yes its ant, its developed by apache.

cd /usr/local/src
wget http://apache.cs.utah.edu//ant/binaries/apache-ant-1.8.2-bin.tar.gz
tar zxvf apache-ant-1.8.2-bin.tar.gz
mv apache-ant-1.8.2 /usr/local/ant

3. Export correct path/directory  for Ant and Java

export ANT_HOME=/usr/local/ant
export JAVA_HOME=/usr/lib/jvm/java
export PATH=$PATH:/usr/local/ant/bin
export CLASSPATH=.:$JAVA_HOME/lib/classes.zip

if you wish all of your user to  use above path everytime they logged in into ssh, you can add those path to /etc/bashrc so that they dont need to type it eveytime.

echo 'export ANT_HOME=/usr/local/ant' >> /etc/bashrc
echo 'export JAVA_HOME=/usr/lib/jvm/java' >> /etc/bashrc
echo 'export PATH=$PATH:/usr/local/ant/bin' >> /etc/bashrc
echo 'export CLASSPATH=.:$JAVA_HOME/lib/classes.zip' >>/etc/bashrc

ingredient prepared, next step is cook the red5.

4. Download and Install RED5 Server

cd /usr/local/src
svn checkout http://red5.googlecode.com/svn/java/server/trunk/ red5
mv red5 /usr/local/
cd /usr/local/red5
ant prepare
ant dist

After you saw bunch of line then you will noticed BUILD SUCCESSFUL that mean the process is successfully done.
5. Copy Required file from dist/conf folder to main folder of red5

cp -r dist/conf /usr/local/red5

6. Test and run it

sh red5.sh

You will get alot of line as well, once it stopped, you will found the word: bootstrap complete to indicate the red5 started successfully. To exit the process with putty type: ctrl + z, ctrl + c. If you saw error on the last few line, mean the red5 is not compiled correctly, maybe you missing something like java or ant.
7. Test it with browser
Open any browser the insert the url http://yourserverip:5080/

you will saw something like below:

Troubleshooting:

1, All success but open in url become 404.
#port 5080 might get blocked with your firewall? Solution is allow port 5080 and 1935 to your firewall.
2, latest version is buggy for you?
#no problem, check out old version here: http://red5.googlecode.com/svn/java/server/tags/
3, If you get bash: svn: command not found
#no problem, i have a tutorial for install svn
4, other problem? please use the following comment box, i will try my best to help you.

thats all, cheers and happy 2012 new year.

We use .htaccess to rewrite and redirect link. When you get your new hosting its always there is easy step to verify if .htaccess is working fine or not on your new hosting account. Some hosting does not configure their apache server correctly and caused .htaccess is not working even the code itself is correct. So, Here is simple step that might useful for you to verify if the .htaccess is work or not working. (with these instruction, make sure you have root access to your server)

First of all you will need to check if mod_rewrite is enabled for apache.

cat /etc/httpd/conf/httpd.conf | grep rewrite

make sure you see result below:
LoadModule rewrite_module modules/mod_rewrite.so
if you dont see above line, then you will need to add it. If yes you can proceed to 2nd step

make sure AllowOverride inside httpd.conf is set to All instead of none by default.
example show on below:

    Options FollowSymLinks
    AllowOverride none

change to :

    Options FollowSymLinks
    AllowOverride All

Dont forget to restart apache after making change to AllowOverride. /var/www/html is example of mine, you can replace it to your directory example: /home/user/public_html

What next? Test it!!

Open notepad and copy and paste the following code into it:

<?php // htaccess tester // Copyright 2011 Booser if($_GET['url']==1){echo "Damn it! looks like htaccess is not working, please refer to: Booser Verify Htaccess for solution";} elseif($_GET['url']==2){echo" YES!! Your .htaccess is work fine man!";} else{echo"Linux Apache mod_rewrte Test Tutorial";} ?>

LINK1 = rewrite.php?link=1

LINK2 = link2.html

Click on Link1 and Link2, they both are same file, if you clicked link2 not work or get 404 mean its not working you will need to refer Booser Verify htaccess for solution

If you like Booser, you can copy this code and paste it to your website. Verify if .htaccess is working or not

Save it as: rewrite.php
Next step is open a new notepad again and paste following into it:

RewriteEngine On
RewriteRule ^my-rewite-link([^/]*).html$ rewrite.php?url=$1 [L]

Save it as: .htaccess

Now upload both files to your server using ftp, so that you can access it from url:

http://www.yourcoolsite.com/rewrite.php

click on Link1 and Link2 to test them out.

If you get:

404 error its mean, you dont have mod_rewite installed correctly or allowOveride is none.
500 internal error mean that you have some problem with .htaccess files make sure you copy them correctly.

You can contact your hosting to check if you not sure what you are going to do, or drop me a message on contact page, i would happily to check it for you.

Hope that help.
~Cheers~

/etc/skel directory

The system will copy the contents of the /etc/skel directory to the user’s HOME directory.

The useradd command allows an administrator to create a default HOME directory configuration, then uses that as a template to create the new user’s HOME directory. This allows you to place default files for the system in every new user’s HOME directory automatically. On my Linux system, the /etc/skel directory has the following files.

root@mycoolserver:/etc/skel# ls -ld *

The umask value is just that, a mask. It masks out the permissions you don’t want to give.The umask value is subtracted from the full permission set for an object. The full permission for a file is mode 666 (read/write permission for all), but for a directory it’s 777 (read/write/execute permission for all).

umask command shows and sets the default permissions:

root@mypowerserver:~# umask 0022

Thus, in the example, the file starts out with permissions 666, and the umask of 022 is applied, leaving a file permission of 644. The umask value is normally set in the /etc/profile startup file.

Often when surfing website, you found:

Site error: the file /home/USER/public_html/index.php requires the ionCube PHP Loader ioncube_loader_lin_X.X.so to be installed.

here is the way to resolve it:

Create a ‘php.ini’ and add following:

zend_extension = /home/USER/public_html/ioncube/ioncube_loader_lin_4.X.so

Download ioncube_loader_lin_4.X.so from : http://www.ioncube.com/loaders.php
and upload ioncube_loader_lin_4.X.so to /home/USER/public_html/ioncube/
Replace USER with the username of the cpanel account you are uploading the php.ini file to.

Replace “X” with the appropriate version of the ioncube loader

Upload the php.ini to your public_html directory.

If you are running your script from a directory other than public_html – for example /home/USER/public_html/blog/index.php you will need to upload the php.ini file to that directory.

Hope that help.
