Aiuto configurazione VPS

**diarex** · 19-04-2011, 15:12

Ciao,

ancora problemi, ho deciso di postare quindi la configurazione completa effettuata per capire l'errore dove sta.

La VPS ha 1.6 GByte di RAM, 15 GByte di HD, Plesk 8.3.1. Aruba VPS Professional per gli altri dettagli.

Uso FastCGI per poter avere lo stesso utente sia via FTP che quando gira il Php.

FastCGI

Desktop - Updater
Seleziono la versione di Plaek (è in giallo)
Scelgo FastCGI quindi in alto Install
.... attendo ...

Configurazione Apache

Uno dei problemi incontrati è il msg di errore "too much process", ho risolto con:

Codice:

# vi /etc/httpd/conf/httpd.conf
    
    ...
    <IfModule prefork.c>
        StartServers      10
        MinSpareServers    5
        MaxSpareServers   75
        ServerLimit      512
        MaxClients       512
        MaxRequestsPerChild  0
    </IfModule>
    ...

Configurare il FastCGI

Assieme al precedente ho operato così:

Codice:

# vi /etc/httpd/conf.d/fcgid.conf
    
        # added by psa-mod-fcgid-configurator
        LoadModule fcgid_module /usr/lib/httpd/modules/mod_fcgid.so

        <IfModule mod_fcgid.c>
          SocketPath /var/lib/httpd/fcgid/sock
        </IfModule>

        # added by psa-mod-fcgid-configurator
        <IfModule mod_fcgid.c>
            IdleTimeout 3600
            ProcessLifeTime 7200
            MaxProcessCount 256
            DefaultMaxClassProcessCount 32
            IPCConnectTimeout 30
            IPCCommTimeout 45
            DefaultInitEnv RAILS_ENV production
        </IfModule>

In effetti l'errore "too much process" non è più comparso.

Sessioni

Devo rendere la sessione scrivibile a tutti:

Codice:

# chmod 777 /var/lib/php/session/

esagero lo so, qualcuno magari mi può consigliare qualcos'altro...

Abilitare il FastCGI nei siti - VERSIONE A

Per prima cosa copio il file necessario:

Codice:

cp /usr/bin/php-cgi /var/www/vhosts/{DOMINIO}/bin/
chown -R {UTENTEFTP}:psacln /var/www/vhosts/{DOMINIO}/bin/

Impongo la lettura un un .conf personale:

Codice:

#vi /var/www/vhosts/{DOMINIO}/conf/httpd.include
                
       ....
                
       Include /var/www/vhosts/{DOMINIO}/conf/vhost.conf

Quindi edito il .conf:

Codice:

#vi /var/www/vhosts/{DOMINIO}/conf/vhost.conf
        
                AddHandler fcgid-script .php
                SuexecUserGroup {UTENTEFTP} psacln
                
                <Directory /var/www/vhosts/{DOMINIO}/httpdocs>
                    FCGIWrapper /var/www/vhosts/{DOMINIO}/bin/php-cgi .php
                    Options +ExecCGI +FollowSymLinks
                </Directory>

ed un restart:

Codice:

#/etc/init.d/httpd restart

Abilitare il FastCGI nei siti - VERSIONE B

In questa configurazione uso un wrapper non composto dal semplice binario, ma da uno script:

Codice:

vim /var/www/vhosts/{DOMINIO}/bin/php-cgi.fcgi

    #!/bin/sh
    # Set desired PHP_FCGI_* environment variables.
    # Example:
    # PHP FastCGI processes exit after 500 requests by default.
    PHP_FCGI_MAX_REQUESTS=10000
    export PHP_FCGI_MAX_REQUESTS

    # Replace with the path to your FastCGI-enabled PHP executable
    exec /var/www/vhosts/{DOMINIO}/bin/php-cgi

Copio quindi il binario ed assegno i permessi corretti:

Codice:

    cp /usr/bin/php-cgi /var/www/vhosts/{DOMINIO}/bin/
    chown -R {UTENTEFTP}:psacln /var/www/vhosts/{DOMINIO}/bin/
    chmod 755 /var/www/vhosts/{DOMINIO}/bin/php-cgi.fcgi

Imposto il file di configurazione del vhost come segue:

Codice:

vim /var/www/vhosts/{DOMINIO}/conf/vhost.conf

SuexecUserGroup {UTENTEFTP} psacln
<Directory /var/www/vhosts/{DOMINIO}/httpdocs>
    AddHandler fcgid-script .php
    FCGIWrapper /var/www/vhosts/{DOMINIO}/bin/php-cgi.fcgi .php
    Options +ExecCGI +FollowSymLinks
</Directory>

Ed infine impongo la lettura del mio conf esattamente come prima

Codice:

vi /var/www/vhosts/{DOMINIO}/conf/httpd.include
                
....
Include /var/www/vhosts/{DOMINIO}/conf/vhost.conf

ed un restart:

Codice:

#/etc/init.d/httpd restart

Problemi Ottenuti

Ecco cosa appare una volta al giorno:

Ovvero i processi cadono uno dietro l'altro, dopo pochi minuti la situazione torna normale.

idee?

La pagina esce fuori bianca o ti restituisce errore 500?

**diarex** · 20-04-2011, 09:38

Dovrebbe essere un "Internal Server Error", io personalmente non ho avuto la fortuna di vederlo mai, però dalle segnalazioni degli amministratori dei vari siti, confrontando gli orari nei log, pare che sia proprio un errore 500.

La pagina bianca invece veniva mostrata quando c'erano problemi di "too much process".
