Apache processes not running as user?

Post by Omar » Sat Jan 05, 2013 12:46 am

I'm not sure, but the process for the user apache not runs as a user?, this is so or am I doing something wrong?
If I'm not wrong, how manage customer processes?

ok, the problem is phpfcgid template (is not working).

create a index.php into public_html:
$ vim index.php
<?php
phpinfo();
?>

then if I go to web site, only see the text:
<?php
phpinfo();
?>

and not the result :(

if it worked then you should run the process /usr/bin/php-cgi as a user,for example ($ ps -ef f):
apache \_ /usr/sbin/httpd
user | \_ /usr/bin/php-cgi

There was a bug in installer and you might face it if you installed control panel before 19th december.

If it is the case then please try this:

Code: Select all

yum install mod_fcgid
yum update vesta

cd /usr/local/vesta/data/templates/web/
wget http://c.vestacp.com/0.9.7/templates/web/apache_phpfcgid.sh -O apache_phpfcgid.sh
wget http://c.vestacp.com/0.9.7/templates/web/apache_phpfcgid.tpl -O apache_phpfcgid.tpl
wget http://c.vestacp.com/0.9.7/templates/web/apache_phpfcgid.stpl -O apache_phpfcgid.stpl

for user in $(v-list-sys-users plain); do v-rebuild-web-domains $user;done

I think it's a new bug, because I installed vesta after 19th december and these 3 files are identical to files that are
/usr /local/vesta/data/templates/web/

I solved the problem with roundcubemail, the config file (/etc/httpd/conf.d/roundcubemail.conf) now is like:

<IfModule prefork.c>
LoadModule php5_module modules/libphp5.so
</IfModule>
<IfModule !prefork.c>
LoadModule php5_module modules/libphp5-zts.so
</IfModule>

Alias /roundcubemail /usr/share/roundcubemail
Alias /webmail /usr/share/roundcubemail

<Directory /usr/share/roundcubemail/>
AddType application/x-httpd-php .php
Order Deny,Allow
Deny from all
Allow from all
</Directory>

Thank you for workaroud Omar. I tried to reproduce this bug in my sand box, but I couldn't. So it's not clear to me why phpfcgi template didn't worked out. What you did was complete switch from mod_php to mod_fcgid, which is ok, but both modules should work together without problems. It looks like template triggerer didn't completed succsesfuly or it didn't even started.

When you create website vesta checks if there is shell script for chosen template and if it has execution flag.

Code: Select all

# Running template trigger
if [ -x $WEBTPL/apache_$template.sh ]; then
    $WEBTPL/apache_$template.sh $user $domain $ip $HOMEDIR $docroot
fi
So please make sure that file /usr/local/vesta/data/templates/web/apache_phpfcgid.sh is executable. You can also run it manualy as root any time, just replace $user $domain $ip $HOMEDIR $docroot variable with appropriate values.

Code: Select all

/usr/local/vesta/data/templates/web/apache_phpfcgid.sh admin v-test.vestacp.com 127.0.0.1 /home  /home/admin/web/v-test.vestacp.com/public_html

I checked everything.

The phpfcgi template work only when i comment the file /etc/httpd/conf.d/php.conf, if look this file, you can see:

Code: Select all

<FilesMatch \.php$>
    SetHandler application/x-httpd-php
</FilesMatch>
then all php process runs as httpd, not user. I think that is the problem.

Ok let's compare our setups. I will use user admin and domain v-test.vestacp.com in my example. After creating new domain with phpfcgi template I see following:

Code: Select all

[root@v-test ~]# v-list-web-domain admin v-test.vestacp.com
DOMAIN:       v-test.vestacp.com
IP:           67.43.11.16
IP6:          NULL
U_DISK:       2
U_BANDWIDTH:  0
TPL:          phpfcgid
ALIAS:        www.v-test.vestacp.com

SSL_HOME:     same
FTP_USER:     NULL
NGINX:        default
NGINX_EXT:    jpg,jpeg,gif,png,ico,svg,css,zip,tgz,gz,rar,bz2,exe,pdf,doc,xls,ppt,txt,odt,ods,odp,odf,tar,bmp,rtf,js,mp3,avi,mpeg,flv,html,htm
SUSPENDED:    no
TIME:         08:15:38
DATE:         2013-01-09

This is apache configuration /home/admin/conf/web/httpd.conf

Code: Select all

<VirtualHost 67.43.11.16:8080>

    ServerName v-test.vestacp.com
    ServerAlias www.v-test.vestacp.com
    ServerAdmin [email protected]
    DocumentRoot /home/admin/web/v-test.vestacp.com/public_html
    ScriptAlias /cgi-bin/ /home/admin/web/v-test.vestacp.com/cgi-bin/
    Alias /vstats/ /home/admin/web/v-test.vestacp.com/stats/
    Alias /error/ /home/admin/web/v-test.vestacp.com/document_errors/
    SuexecUserGroup admin admin
    CustomLog /var/log/httpd/domains/v-test.vestacp.com.bytes bytes
    CustomLog /var/log/httpd/domains/v-test.vestacp.com.log combined
    ErrorLog /var/log/httpd/domains/v-test.vestacp.com.error.log
    <Directory /home/admin/web/v-test.vestacp.com/public_html>
        AllowOverride AuthConfig FileInfo Indexes Limit
        Options +Includes -Indexes +ExecCGI
        php_admin_flag engine off
        AddHandler fcgid-script .php
        FCGIWrapper /home/admin/web/v-test.vestacp.com/cgi-bin/fcgi-starter .php
    </Directory>
    <Directory /home/admin/web/v-test.vestacp.com/stats>
        AllowOverride All
    </Directory>
    Include /home/admin/conf/httpd.v-test.vestacp.com.conf*

</VirtualHost>
As you can see there is additional handler "AddHandler fcgid-script .php" wich overrides setting in /etc/httpd/conf.d/php.conf

Ok now I will list file permissions:

Code: Select all

[root@v-test ~]# ls -all /home/admin/web/v-test.vestacp.com/cgi-bin/
total 12
drwxr-x--x 2 admin admin 4096 Jan  9 08:41 .
dr-xr-x--x 9 admin admin 4096 Jan  9 08:15 ..
-rwxr-x--x 1 admin admin  119 Jan 10 05:04 fcgi-starter
[root@v-test ~]# ls -all /home/admin/web/v-test.vestacp.com/public_html/
total 20
drwxrwx--x 2 admin admin 4096 Jan 10 05:24 .
dr-xr-x--x 9 admin admin 4096 Jan  9 08:15 ..

-rw-rw-r-- 1 admin admin   22 Jan  9 08:16 index.php
-rw-rw-r-x 1 admin admin   65 Jan  9 08:15 robots.txt
and just in case wrapper content

Code: Select all

[root@v-test ~]# cat /home/admin/web/v-test.vestacp.com/cgi-bin/fcgi-starter 
#!/bin/sh
PHPRC=/etc/
export PHPRC
export PHP_FCGI_MAX_REQUESTS=1000
export PHP_FCGI_CHILDREN=8
exec /usr/bin/php-cgi
