I would like to redirect www.example.it to www.example.com/index-it.php

The website is just a one-page site.

I would like that to happen transparently, in the sense that www.example.it will be still displayed on the address bar after the redirect.

I have tried this but it generates an Internal Server Error.

<VirtualHost *:80>
ServerName www.example.it

RewriteEngine on
RewriteRule ^/.*$ http://www..com/index-it.php [P,L]

</VirtualHost>

This would work instead, but it doesn't provide a transparent redirect:

<VirtualHost *:80>
ServerName www.example.it

RewriteEngine on
#RewriteRule ^/.*$ http://www.example.com/index-it.php [P,L]

Redirect 301 / http://www.example.com/index-it.php

</VirtualHost>

Any idea, please? Thanks.

I need to install MySQL 5.6 (this very version) on my Amazon EC2 AMI but I can't find a way.

The version currently installed is this one: 

mysql  Ver 14.14 Distrib 5.5.20, for Linux (x86_64) using readline 5.1

And if I go to the MySQL website, I can find only the version 5.5.25:
http://www.mysql.com/downloads/mysql/

Would you know how to install it?

And if I can't yet, where can I find how long I need to wait?

I have set up Postfix on my CentOS server.

If the subject of the email contains some non-English characters (i.e.: accented letters), it gets ruined.

Here is an example.

Original subject:

this is a testà è ciao

Subject, once delivered to the server:
=?ISO-8859-1?Q?this_is_a_test=E0_=E8_ciao?=

I know it is now an issue with MUAs because: _ A lot of users have reported the issue - thus the MUA of the sender is out of the equation
_ I check the raw email on the server (I access the actual file with VI)

I guess it is a problem with charset, but I can't find anywhere in the Postfix config files how to handle the charset.

Thanks,
Dan

I have a CentOS server on a production environment. I need to update the PHP package that I installed using the REMI repository.

Quite easy:

yum update php

But what is it going to happen if something goes wrong during the update? How can I rollback?

What's the best technique to make sure not to compromise a production server due to an update?

Is it maybe better to compile PHP from the source, rather than using a binary package?

EDIT: I am not afraid of incompatibility between my code and the new PHP version (I have well tested that on development). I am more afraid of something going wrong while CentOS updated the binary (power cut, lost connection, unexpected conflit)

Thanks,
Dan

I run this from a cronjob:

tar -czvf /var/backups/svn.tgz /var/svn/*

That generates this on stderr:

tar: Removing leading `/' from member names

I would like to avoid this because it is not a real error (for me!). I want on stderr only things that I should worry about?

How can I kill that message?

I have the feeling that it is a matter of using the tar -C option but I am not sure and I don't know how.

Thanks for the help,
Dan

I am running CentOS and using the remi repository for PHP.

I have just found out I am using the development version of PHP, even if I need the stable version:

PHP 5.3.4-dev (cli) (built: Oct  3 2010 10:57:19)

I think that is because the content of my /etc/yum.repos.d/remi.repo is:

[remi]
name=Les RPM de remi pour Enterprise Linux 5 - $basearch
baseurl=http://rpms.famillecollet.com/el5.$basearch/
        http://iut-info.univ-reims.fr/remirpms/el5.$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi
failovermethod=priority

[remi-test]
name=Les RPM de remi en test pour Enterprise Linux $releasever - $basearch
baseurl=http://rpms.famillecollet.com/test-el5.$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-remi

I mean, I left the [remi-test] section.

How can I downgrade to the latest stable version of PHP (5.3.3)?

I have tried to comment the [remi-test] section and run yum update php but this is the message: 

No Packages marked for Update

Has anybody know how to do it, please?

Thanks,
Dan

I am using WebSVN.

It is quite cool but its cache directory is 6GB!

I would like to disable the cache (which is not very important for my application) or, at least, limit it.

I have checked the configuration file in in include/config.php but I haven't found the way.

Does anybody know how to do that?

Thanks,
Dan

You would like to be notified via email of errors occurring while executing cron jobs.

I use CentOS and the file /etc/crontab for the configuration.

The first step I have done is:

MAILTO=my_email_address

and then I have appended this to each crontab entry:

2>/dev/null

That means this

24 4 * * * root /usr/sbin/ntpdate pool.ntp.org

becomes:

24 4 * * * root /usr/sbin/ntpdate pool.ntp.org 2>/dev/null

In that way I should suppress the normal output and let error messages be sent.

I would like to know if you think what I have done is right and whether that has got any pitfall.

Thanks, Dan
