Subject [users@httpd] Apache2 restart issues
Date Sat, 13 Aug 2005 11:02:03 GMT
Hi,

I have been trying to move from prefork to worker MPM on apache 2.

I have a problem however. The compilation runs perfectly, the server
starts fine.

When I restart the daemon it doesn't finish killing all of apaches
processes before starting the service again. Because of this it fails
the restart with:

Starting httpd: (98)Address already in use: make_sock: could not bind
to address xxx.xxx.xxx.xxx:80
no listening sockets available, shutting down
Unable to open logs

That said, if I then restart it again a few seconds later it will do
so correctly. This is because all of the processes have been
terminated and apache can start again.

Any ideas what could be causing this ?

I have a very basic setup - with PHP4.4.0

Here are my PHP compilation options:

./configure --prefix=/usr/share --datadir=/usr/share/php
--with-apxs2=/usr/sbin/apxs  --with-mysql=/usr --bindir=/usr/bin
--libdir=/usr/share --includedir=/usr/include --with-_lib=lib
--with-config-file-path=/etc --with-exec-dir=/usr/lib/php/bin
--disable-debug --enable-calendar --enable-magic-quotes
--enable-track-vars --with-xml --with-curl --with-zlib-dir=yes
--with-gd --with-jpeg-dir=/usr --with-png-dir --enable-gd-native-ttf
--with-ssl

Here are my Apache compilation options:

export CFLAGS="-O2 -march=i686 -funroll-loops -D_REENTRANT
-D_SINGLE_LISTEN_UNSERIALIZED_ACCEPT -fPIC"
