failure to restart apache2

[cliftonbazaar]

When I restarted apache2 I had several errors and after searching google I have managed to solve them all except the following.
I really don't know which file I should be looking in for this, all I have done is add more virtual hosts and that was a simple 'copy and paste' job.

www@server:/etc/apache2/sites-enabled$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2
[Wed Mar 10 18:39:42 2010] [error] (EAI 5)No address associated with hostname: Could not resolve host name *.80 -- ignoring!
[Wed Mar 10 18:39:42 2010] [error] (EAI 5)No address associated with hostname: Could not resolve host name *.80 -- ignoring!
[fail]

[Ryan Dwyer]

In the vhosts file you probably wrote *.80 instead of *:80.

[cliftonbazaar]

Thanks for that, now I have the error -
www@server:/etc/apache2/sites-available$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2
[Wed Mar 10 19:59:54 2010] [warn] NameVirtualHost *:80 has no VirtualHosts
[Wed Mar 10 19:59:54 2010] [warn] NameVirtualHost *:80 has no VirtualHosts


Where log file should I look at for more info?

I assume you mean the apache2.conf file
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "/var/log/apache2/foo.log"
# with ServerRoot set to "" will be interpreted by the
# server as "//var/log/apache2/foo.log".
#

### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs-2.1/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
ServerRoot "/etc/apache2"
#ServerRoot "/home/www/websites"

#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
#<IfModule !mpm_winnt.c>
#<IfModule !mpm_netware.c>
LockFile /var/lock/apache2/accept.lock
#</IfModule>
#</IfModule>

#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}

#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 60

#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On

#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100

#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.

[sahabcse]

just comment out the entry NameVirtualHost *:80

#NameVirtualHost *:80

then restart the apache.

[cliftonbazaar]

If I comment out just
#NameVirtualHost *:80
then I get
www@server:/etc/apache2/sites-enabled$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2 ... waiting [fail]
If I comment out both of these lines
#Include /etc/apache2/sites-enabled/
#NameVirtualHost *:80
then I get
www@server:/etc/apache2/sites-enabled$ sudo /etc/init.d/apache2 restart
* Restarting web server apache2

so it started but cannot be seen on any other computer.

[sahabcse]

are you trying to access your box from local or public?

check is it resolving locally

in your system pls check in browser


http://localhost

[cliftonbazaar]

http://localhost/ gives me a 'problem loading page' error.

[sahabcse]

paste the o/p of

sudo /etc/init.d/apache2 status

ps -ax | grep apache2

[cliftonbazaar]

www@server:/etc/apache2/sites-enabled$ sudo /etc/init.d/apache2 status

[sahabcse]

apache not running now your system.

sudo /etc/init.d/apache2 start

[sahabcse]

have you create any virtualhost entry there. If it is means pls paste that entry also

[cliftonbazaar]

This is the only Virtual host configuration that I have created in a file
# Include the virtual host configurations:
Include /etc/apache2/sites-enabled/
NameVirtualHost *:80


ports.conf =
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz

NameVirtualHost *:80
Listen 80

<IfModule mod_ssl.c>
# SSL name based virtual hosts are not yet supported, therefore no
# NameVirtualHost statement here
Listen 443
</IfModule>

[sahabcse]

the issue due to the virtualhost entry. pls follow below url for more info

https://help.ubuntu.com/9.10/serverguide/C/httpd.html

[edirlf]

In the vhosts file you probably wrote *.80 instead of *:80.

Thank you for your answer. I was with the same problem and was exactly this.

[sammie12340]

Why use Apache? it's slow and big.
why dont use ngix or lighttpd
just type:
sudo apt-get install lighttpd

This work much better :D
