Help - problem after config subversion

[satimis]

Hi folks,

ubuntu-6.06.1-LAMP-server

This is a test on building a server.

I followed
Setup Subversion with Apache2 on Ubuntu
http://www.jessejcollins.com/blog/index.php?/archives/32-How-To-Setup-Subversion-with-Apache2-on-Ubuntu.html


encountering problem on running;
$ sudo /etc/init.d/apache2 restart
* Forcing reload of apache 2.0 web server...
[Mon Nov 06 11:50:49 2006] [crit] Apache is running a threaded MPM, but
your PHP Module is not compiled to be threadsafe. You need to recompile
PHP.
Pre-configuration failed [fail]

Whether I need to re-install PHP and reconfig it thereafter? Please help. TIA

Which Apache MPM are you using? You must use the prefork MPM, otherwise you cannot use PHP as an Apache module.

Hi falko,

Tks for your advice.

Which Apache MPM are you using? You must use the prefork MPM, otherwise you cannot use PHP as an Apache module.

$ sudo apt-cache search apache2 | grep mpm
apache2-mpm-perchild - experimental high speed perchild threaded model for Apache2
apache2-mpm-prefork - traditional model for Apache2
apache2-mpm-worker - high speed threaded model for Apache2

$ which apache2-mpm
No printout

$ sudo find / -name apache2-mpm
No printout

I hesitate whether it has been installed?

The small tool "equery" is not installed on the PC. Nor can I find the package offering this tool.

$ sudo equery l apache2-mem
sudo: equery: command not found


$ which equery
no printout

Tks


Edit-1:- * * *

$ ls /etc/apache2/mods-enabled/ | grep mpm
$ ls /etc/apache2/mods-available/ | grep mpm
both no printout

You can find out about your MPM by running

apache2 -V

A sample output looks like this:

Server version: Apache/2.0.54
Server built: Sep 5 2005 11:15:09
Server's Module Magic Number: 20020903:9
Architecture: 32-bit
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/prefork"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS

Hi falko,

You can find out about your MPM by running

apache2 -V

$ apache2 -V
Server version: Apache/2.0.55
Server built: Jul 26 2006 18:01:22
Server's Module Magic Number: 20020903:11
Architecture: 64-bit
Server compiled with....
-D APACHE_MPM_DIR="server/mpm/prefork"
-D APR_HAS_SENDFILE
-D APR_HAS_MMAP
-D APR_HAVE_IPV6 (IPv4-mapped addresses enabled)
-D APR_USE_SYSVSEM_SERIALIZE
-D APR_USE_PTHREAD_SERIALIZE
-D SINGLE_LISTEN_UNSERIALIZED_ACCEPT
-D APR_HAS_OTHER_CHILD
-D AP_HAVE_RELIABLE_PIPED_LOGS
-D HTTPD_ROOT=""
-D SUEXEC_BIN="/usr/lib/apache2/suexec2"
-D DEFAULT_PIDLOG="/var/run/apache2.pid"
-D DEFAULT_SCOREBOARD="logs/apache_runtime_status"
-D DEFAULT_LOCKFILE="/var/run/apache2/accept.lock"
-D DEFAULT_ERRORLOG="logs/error_log"
-D AP_TYPES_CONFIG_FILE="/etc/apache2/mime.types"
-D SERVER_CONFIG_FILE="/etc/apache2/apache2.conf"


Following line looks different from your sample;
-D DEFAULT_PIDLOG="/var/run/apache2.pid"


" -D APACHE_MPM_DIR="server/mpm/prefork"" is there.

Tks.

So your Apache is using the correct MPM...
Can you post the part of /etc/apache2/apache2.conf that looks like this?

Hi falko,

Apache2 is now running.

$ sudo /etc/init.d/apache2 restart
Password:

[ ok ]

After changing the line on;
/etc/apache2/ports.conf
Listen 80 Listen 40

to
Listen 80
Listen 44

They must be in 2 lines.


Shall I make any change on your suggestion?
