While performing Step 15 ("Installing Apache2 With mod_php, mod_fcgi/PHP5, And suPHP ") of "The Perfect Server - CentOS 6.2 x86_64 With Apache2 [ISPConfig 3]" phpMyAdmin stopped working. In fact, every time that I access phpMyAdmin, one of Apache's child processes dies: Code: [eric@ispconfig-1 suphp-0.7.1]$ sudo tail -f /var/log/httpd/error_log ... [Thu Jan 12 21:35:38 2012] [notice] Apache/2.2.15 (Unix) DAV/2 mod_fcgid/2.3.6 PHP/5.3.3 mod_ssl/2.2.15 OpenSSL/1.0.0-fips configured -- resuming normal operations [Thu Jan 12 21:35:52 2012] [notice] child pid 2145 exit signal Segmentation fault (11) [Thu Jan 12 21:36:51 2012] [notice] child pid 2146 exit signal Segmentation fault (11) [Thu Jan 12 21:36:55 2012] [notice] child pid 2147 exit signal Segmentation fault (11) I created the configuration file for suphp using the sample file (/tmp/suphp-0.7.1/doc/suphp.conf-example) and modified according to the recipe (e.g., webserver_user=apache)... Code: [global] ;Path to logfile logfile=/var/log/httpd/suphp.log ;Loglevel loglevel=info ;User Apache is running as webserver_user=apache ;Path all scripts have to be in docroot=/var/www:${HOME}/public_html ;Path to chroot() to before executing script ;chroot=/mychroot ; Security options allow_file_group_writeable=false allow_file_others_writeable=false allow_directory_group_writeable=false allow_directory_others_writeable=false ;Check wheter script is within DOCUMENT_ROOT check_vhost_docroot=true ;Send minor error messages to browser errors_to_browser=false ;PATH environment variable env_path=/bin:/usr/bin ;Umask to set, specify in octal notation umask=0077 ; Minimum UID min_uid=100 ; Minimum GID min_gid=100 [handlers] ;Handler for php-scripts x-httpd-php="php:/usr/bin/php" ;Handler for CGI-scripts x-suphp-cgi="execute:!self" Any ideas what might be causing this?
This problem persists even after removing the suphp configuration file and restarting apache!

After a while of trial and error, it turns out to be eaccelerator the problem... After removing it, everything starts to work magically....
Works for me too: Code: [eric@ispconfig-1 ~]$ sudo yum erase `rpm -qa | grep accel` Loaded plugins: fastestmirror, priorities, security Setting up Remove Process Resolving Dependencies --> Running transaction check ---> Package php-eaccelerator.i686 1:0.9.6.1-1.el6 will be erased --> Finished Dependency Resolution Dependencies Resolved ============================================================================== Package Arch Version Repository Size ============================================================================== Removing: php-eaccelerator i686 1:0.9.6.1-1.el6 @epel 313 k Transaction Summary ============================================================================== Remove 1 Package(s) Installed size: 313 k Is this ok [y/N]: y Downloading Packages: Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Erasing : 1:php-eaccelerator-0.9.6.1-1.el6.i686 1/1 Removed: php-eaccelerator.i686 1:0.9.6.1-1.el6 Complete! [eric@ispconfig-1 ~]$ sudo mv suphp.conf /etc [eric@ispconfig-1 ~]$ sudo service httpd restart Stopping httpd: [ OK ] Starting httpd: [ OK ] Thanks, Eddie!
Hey, Falko: Any ideas why eaccelertor is causing segmentation faults? What do you recommend? Is eacelerator important/necessary? What should we do?
If eAccelerator is giving you problems, you can use APC or Xcache instead. All three are PHP opcode caches that speed up PHP execution a lot, therefore it's strongly recommmended to have one installed.
Hey, Falko: I guess that my point here is that I installed eAccelerator (as per the HOWTO) and it didn't work so I'm hoping that you might know why.
Hi to ALL, Im new to linux and busy with step 15 as per Eric Pretorius . my problem is with the follwoing step : Next we install suPHP (there is a mod_suphp package available in the repositories, but unfortunately it isn't compatible with ISPConfig, therefore we have to build suPHP ourselves): cd /tmp wget http://suphp.org/download/suphp-0.7.1.tar.gz tar xvfz suphp-0.7.1.tar.gz cd suphp-0.7.1/ ./configure --prefix=/usr --sysconfdir=/etc --with-apr=/usr/bin/apr-1-config --with-apxs=/usr/sbin/apxs --with-apache-user=apache --with-setid-mode=owner --with-php=/usr/bin/php-cgi --with-logfile=/var/log/httpd/suphp_log --enable-SUPHP_USE_USERGROUP=yes make make install I get the following error after running the command: ./configure --prefix=/usr --sysconfdir=/etc --with-apr=/usr/bin/apr-1-config --with-apxs=/usr/sbin/apxs --with-apache-user=apache --with-setid-mode=owner --with-php=/usr/bin/php-cgi --with-logfile=/var/log/httpd/suphp_log --enable-SUPHP_USE_USERGROUP=yes checking for APR ... configure:error: the --with-apr parameter is incorrct.it must specify an install prefix,a build directory or an apr-config file thankyou !!!!
