D'oh.. so if I understood correctly I should create a new group. Add the FTP user I created to that group and the root user too. Then I should set this group as owner of the only dirs I'd like to be accessible by the FTP user. The rest should be owned by root. Correct? :)

*shrug* I have no idea what you're actually trying to achieve and from where I'm (drunkenly) sat, it looks like it's more complicated than it should be...

eheh :lol:
All my /home/www subdirs (so also /cache, /attachments, etc) have 'root' as group and 'ftp_user' as owner (at least this is what WinSCP is telling me). I did this to be sure that the ftp user could only access /home/www and not also the other directories.

Anyway the problem is (as you said) that owner of apache is root..

Another question ( :whistle: ): I have phpmyadmin installed. For every website I host on my VPS (thanks to virtual hosts) I noticed I can access phpmyadmin simply going to website.tld/phpmyadmin.
I'd like to avoid this.. is there a way to only have hostname/phpmyadmin accessible (and not for every website)..?

How is it installed?
Uhm.. I think I just did apt-get install phpmyadmin.. it's in /etc/phpmyadmin
Here's apache.conf:
Code: [Select]
# phpMyAdmin default Apache configuration

Alias /phpmyadmin /usr/share/phpmyadmin

<Directory /usr/share/phpmyadmin>
Options FollowSymLinks
DirectoryIndex index.php

<IfModule mod_php5.c>
AddType application/x-httpd-php .php

php_flag magic_quotes_gpc Off
php_flag track_vars On
php_flag register_globals Off
php_admin_flag allow_url_fopen Off
php_value include_path .
php_admin_value upload_tmp_dir /var/lib/phpmyadmin/tmp
php_admin_value open_basedir /usr/share/phpmyadmin/:/etc/phpmyadmin/:/var/lib/phpmyadmin/
</IfModule>

</Directory>

# Authorize for setup
<Directory /usr/share/phpmyadmin/setup>
    <IfModule mod_authn_file.c>
    AuthType Basic
    AuthName "phpMyAdmin Setup"
    AuthUserFile /etc/phpmyadmin/htpasswd.setup
    </IfModule>
    Require valid-user
</Directory>

# Disallow web access to directories that don't need it
<Directory /usr/share/phpmyadmin/libraries>
    Order Deny,Allow
    Deny from All
</Directory>
<Directory /usr/share/phpmyadmin/setup/lib>
    Order Deny,Allow
    Deny from All
</Directory>

Maybe changing the line Alias /phpmyadmin /usr/share/phpmyadmin ..?

Yeah, that's the problem, it's being declared as an Alias, which means it's applicable to all virtual hosts. Normally for virtual hosting that's fine.

What I personally do, should I ever install pMA on a server is install it into a given folder and dump the rest of the stuff into an .htaccess file so it's contained in the one place - I don't use apt-get for that, though.

I don't know what you should do for the best, though.

Quick fix would be to move the Alias to VHost declaration.
The way it's meant to be

You mean adding the line 'Alias /phpmyadmin /usr/share/phpmyadmin' to the 'default' site and removing that line from phpmyadmin's apache.conf?

I restarted the server and now I'm getting this mail every 10 min ~:

In reply to your thought, using mod_php + apache2 in a low-memory situation is a very bad idea. Because on every new request apache forks a new child process and each child process with mod_php in SMF's case takes about 25-60 MB of RAM. And apache does this without any regards of how much of RAM is left. So I can hold F5 on any one of your site and crash your server without much trouble. Solution to this is using PHP-FPM which spawns semi-persistent processes and manages the low RAM scenarios much better. What PHP-FPM does is that it separates the php process into a separate entity instead if being bound into apache, so apache doesn't have to load php on every request even if it's non-php related. This itself saves RAM, plus FPM can restrict the number of open processes thus preventing RAM overflow. FCGI is an interface to use PHP-FPM with Apache2. I used this guide to install FCGI + PHP-FPM on an Ubuntu 12.04 server, this should be fine.

PS : I'm fairly sure what I said here is correct, but I can be wrong. Feel free to correct me in the most humiliating way possible.

EDIT: As a matter of fact, Baidu can single handily take out a website with mod_php in a low RAM situation.

I've experienced a similar issue before with POSTFIX. It turned out that apt did not remove the old sendmail files (just the sendmail-bin). To fix this I did the below:
Code: [Select]
sudo apt-get --purge remove sendmail-base sendmail-cf sendmail-doc

This removed any leftover files form the old sendmail install (including /etc/cron.d/sendmail which causes this error message).

Uhm, I think I'm doing something wrong with the latest thing (adding the lines to your virtualhost section)..
I'm trying with the website heystella.it (located in /home/www/heystella.it/htdocs), here's my site Vhost with the lines added:

Code: [Select]
<VirtualHost *:80>
        ServerAdmin xxxx@xxx.com
        ServerName  heystella.it
        ServerAlias [url=http://www.heystella.it][url=http://www.heystella.it]www.heystella.it[/url][/url]

        # Indexes + Directory Root.
        DirectoryIndex index.html index.cgi index.pl index.php index.xhtml
        DocumentRoot /home/www/heystella.it/htdocs/

        # CGI Directory
        ScriptAlias /cgi-bin/ /home/www/heystella.it/cgi-bin/
        <Location /cgi-bin>
                Options +ExecCGI
        </Location>


        # Logfiles
        ErrorLog  /home/www/heystella.it/logs/error.log
        CustomLog /home/www/heystella.it/logs/access.log combined

        FastCgiExternalServer /home/www/php5.external -host 127.0.0.1:9000
        AddHandler php5-fcgi .php
        Action php5-fcgi /usr/lib/cgi-bin/php5.external
        Alias /usr/lib/cgi-bin/ /home/www/
</VirtualHost>

But if I visit the website I get:

Not Found

The requested URL /usr/lib/cgi-bin/php5.external/index.php was not found on this server.

EDIT: Don't know why now it seems to work... http://heystella.it/test.php
