Install Web2py in virtual hosting - apache2

Install Web2py by a script setup-web2py-ubuntu.sh, previously adjusted the way for their virtual hosting.
But it works only on port 443, and the 80 th issue
It works!
How to fix?

How do I set up LAMP without the forbidden message when viewing my site?

I use a Linux Mint 16 + newest LAMP + Laravel.
I'm getting this error when I try viewing my website either via "localhost" or "127.0.0.1".
Forbidden
You don't have permission to access / on this server.
------------------------------------------------------
Apache/2.4.6 (Ubuntu) Server at 127.0.0.1 Port 80
My setting are as follows:
on /etc/hostname
NameServer ynwlocalwebserver
on /etc/hosts
127.0.0.1 localhost
127.0.1.1 ynwlocalwebserver
# The following lines are desirable for IPv6 capable hosts
::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
I only have one site-enable named "ynwlocalwebserver.conf" it's current contents for the meantime are:

The folder ynw in "/home/ynwmint/ynw/public" is the Laravel project.
I put the chmod of the public folder to 777 (for the meantime) and chown it under www-data:www-data
What am I doing wrong, or what else do I need to check?
Thanks.
Apache 2.4 has some minor changes with regards to config.
This:
ServerName ynwlocalwebserver
DocumentRoot /home/ynwmint/ynw/public

CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory /home/ynwmint/ynw/public>
AllowOverride All
Order allow,deny
Allow from all
</Directory>
Should be changed to this:
<VirtualHost *:80>
ServerName ynwlocalwebserver
DocumentRoot /home/ynwmint/ynw/public
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
<Directory /home/ynwmint/ynw/public>
Options +Indexes +FollowSymlinks + MultiViews
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
Also for added security you may want to this directory rule:
<Directory />
Options FollowSymlinks
AllowOverride None

Apache2 is not wanting to be deleted

I am having trouble removing a VirtualHost, so I thought of just simply editing the /etc/apache2/sites-available/default file. It turns out that I am trying to add the original 'index.html' file, which I have in the /var/www/ directory. But it is not working because another VirtualHost has taken port 80 and I don't see my 'index.html' file listed there in the default file. I am super frustrated, so I am thinking of just doing a fresh install of the apache2 service. But even though I use this command to remove it:
sudo apt-get install --remove apache2 php5 libapache2-mod-php5
Even though I do this, it is not removed and I get this error at the end of the process:
Errors were encountered while processing:
libopenvnc-imgproc2.3
libavfilter2:armhf
libav-tools
ffmpeg
E: Sub-process /usr/bin/dpkg returned an error code (1)
Is there any way to do a fresh install of apache2 along with php5 and libapache2-mod-php5 as I had installed them when I first got my Pi? I am just lost, I have gone to a million forums and none have helped me.....
Here is the 'default' file text:
NameVirtualHost *:8091
NameVirtualHost *:80
NameVirtualHost *:443
This is what I tried doing, but it didn't work, it said the file couldn't be found!
<VirtualHost *:80>
DocumentRoot /var/www/remote_replay.php
ServerName 192.168.1.80
</VirtualHost>
This part below works fine, but I want it removed!!!!!

There is a problem with your virtual host configuration, DocumentRoot must be a directory. If you want to serve a specific file, use DocumentIndex to specify the files to use in order of preference:
<VirtualHost *:80>
DocumentRoot /var/www/
DocumentIndex remote_replay.php index.php index.html index.htm
ServerName 192.168.1.80

Use bottlepy and php in the same computer

I use ubuntu 12.04 with apache2 and mod_wsgi installed. I want to use bottlepy and php in my local computer.
I know such an issue is already asked by someone else as in Apache mod_wsgi and php in the same domain.
But someone suggest me to make a new question since my problem could be different.
I've change /etc/apache2/sites-available/default into this:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www
<Directory />

AllowOverride None
</Directory>

<VirtualHost *>
DocumentRoot /home/gofrendi/workspace/kokoropy
ServerName oraiso
WSGIDaemonProcess kokoropy user=www-data group=www-data processes=1 threads=5
WSGIScriptAlias /kokoropy /home/gofrendi/workspace/kokoropy/kokoro.wsgi
<Directory /home/gofrendi/workspace/kokoropy>
WSGIProcessGroup kokoropy
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
</VirtualHost>
The first virtual host is for PHP, and the second one is for bottlepy.
I put my bottlepy application in /home/gofrendi/workspace/kokoropy. And I have kokoro.wsgi in the same directory which contains this script:
import os
sys.path = [os.path.dirname(__file__)] + sys.path
from kokoropy import kokoro_init
PWD = os.path.dirname(os.path.abspath(__file__))
APP_DIRECTORY = 'applications'
APPLICATION_PATH = os.path.join(PWD, APP_DIRECTORY)
application = kokoro_init(application_path = APPLICATION_PATH, run = False)
I've do enable the configuration by using
sudo a2ensite default
sudo service apache2 restart
My PHP scripts are still work as expected. But, whenever I don't know how to access my bottlepy script.
I've also try to remove the PHP part of /etc/apache2/sites-available/default, so that it only consists of
<VirtualHost *>
DocumentRoot /home/gofrendi/workspace/kokoropy
ServerName oraiso
WSGIDaemonProcess kokoropy user=www-data group=www-data processes=1 threads=5
WSGIScriptAlias /kokoropy /home/gofrendi/workspace/kokoropy/kokoro.wsgi
<Directory /home/gofrendi/workspace/kokoropy>
WSGIProcessGroup kokoropy
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
</VirtualHost>
But I still can't get bottlepy work. It just simply show 404 not found.
Do anybody has the same experience? How to make it work?
Thanks.
The problem has been solved.
First I change httpd.conf setting (or in my case /etc/apache2/sites-available/default) nto this:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
Alias /doc/ "/usr/share/doc/"
<Directory "/usr/share/doc/">
Options Indexes MultiViews FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
Allow from 127.0.0.0/255.0.0.0 ::1/128
</Directory>
# THIS IS WHERE I START TO EDIT IT:
# It tells apache about wsgi existance
WSGIDaemonProcess kokoropy user=www-data group=www-data processes=1 threads=5
WSGIScriptAlias /kokoropy /home/gofrendi/workspace/kokoropy/kokoro.wsgi
<Directory /home/gofrendi/workspace/kokoropy>
WSGIProcessGroup kokoropy
WSGIApplicationGroup %{GLOBAL}
Options ExecCGI
Order deny,allow
Allow from all
</Directory>
</VirtualHost>
This configuration say that localhost/kokoropy should be handled by the wsgi.
My wsgi script is located at /home/gofrendi/workspace/kokoropy/kokoro.wsgi.
kokoro.wsgi content is as follow:
import os, sys
os.chdir(os.path.dirname(__file__))
sys.path = [os.path.dirname(__file__)] + sys.path
from bottle import default_app
#route('/')
def index():
return 'run with apache'
application = default_app()
If you found internal sever error, when accessing bottlepy, but find no error when accessing php, that is probably some mistake in you wsgi. Just open up the apache log (in my case it is here: /var/log/apache2/error.log)

ZPanelcp , Domains activation not work

-Hello everyone , I just rent an a dedicated server (ubuntu 12.4) and i install apache + php, mySQL etc ...but using SSH to creat domains (virtual hosts) it is a litle bit laborer so I decided to install some GUI admin panel and also decided for ZPanelcp last version so everything installed fine without errors and I set first time two domains something like :
new.domain.com
new.otherdomain.com
these domains has been activated successfully without set zpanel DNS for those domains but next day I notice when I try to create again other domains in my ZPanel show as "live" but in my webbrowser can not see so in reality they were not activated , ok first time I Run Daemon again and restart BIND also restart apache I try a few changes in my server conf files but nothing I reboot my server also nothing my server use one static ip.
Here are my Zpanel, apache2 conf files.
Apache2 files:
folder files:

Why doesn't Apache redirect my IP address to the desired location on my server?

I made a simple page /home/david/mainSite/index.html. I then added a virtual host in Apache to redirect my IP address to this page.
<VirtualHost *:80>
ServerName 74.181.105.228
DocumentRoot /home/david/mainSite
</VirtualHost>
However, when I go to 74.181.105.228after restarting Apache, I get a page with this text instead of "index.html."
Welcome to mydomain.com!
This is the default web page for this server.
The web server software is running but no content has been added, yet.
Why does Apache redirect to the default page instead of "/home/david/mainSite/index.html"?
Here is how my "/etc/apache2/sites-available/default" file looks like.
<VirtualHost *:80>

I discovered the answer! It was tricky.
In "apache2.conf", I originally had ServerName 74.181.105.228, which makes accessing 74.181.105.228 via a browser load the default page for my server.
Changing this value in "apache2.conf" to ServerName mydomain.com solves the problem since Apache no longer directs 74.181.105.228 to the default page of my server. In turn, I can direct 74.181.105.228 to load a page from a certain directory in my file system.
My virtual host block still remains
<VirtualHost *:80>
ServerName 74.181.105.228
DocumentRoot /home/david/mainSite
</VirtualHost
