[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-users] debian+xen: System fails to mount swap, mydql not starting, debian kernel install not completing
I am running a xen (2.0.7) kernel on debian testing
(2.6.11) with 3 domU's.
Problems: MySQL doesn't start
My domU's have no swap (e.g. 0k) and
mounting them @ boot fails
my debian kernel give me an error on install
but every thing is available (dom0 booted, and domU's
running).
I was trying to start mysql but it keeps failing with
this message:
Starting MySQL database server: mysqld...failed.
Please take a look at the syslog.
/usr/bin/mysqladmin: connect to server at 'localhost'
failed
error: 'Can't connect to local MySQL server through
socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket:
'/var/run/mysqld/mysqld.sock' exists!
Also my domU's come up with swap 0k.

# This script is called as the last step of the
installation of the
# package. All the package's files are in place, dpkg
has already done
# its automatic conffile handling, and all the
packages we depend of
# are already fully installed and configured.
# summary of how this script can be called:
# * <postinst> `configure'
<most-recently-configured-version>
# * <old-postinst> `abort-upgrade' <new
version>
# * <conflictor's-postinst> `abort-remove'
`in-favour' <package>
# <new-version>
# * <deconfigured's-postinst>
`abort-deconfigure' `in-favour'
# <failed-install-package> <version>
`removing'
# <conflicting-package> <version>
# for details, see
http://www.debian.org/doc/debian-policy/ or
# the debian-policy package
#
# quoting from the policy:
# Any necessary prompting should almost always be
confined to the
# post-installation script, and should be
protected with a conditional
# so that unnecessary prompting doesn't happen if
a package's
# installation fails and the `postinst' is called
with `abort-upgrade',
# `abort-remove' or `abort-deconfigure'.

need protecting
# against being run in the abort-* cases.

# Tell ucf that the file in /usr/share/foo is
the latest
# maintainer version, and let it handle how to
manage the real
# confuguration file in /etc. This is how a
static configuration
# file can be handled:
##:if which ucf >/dev/null 2>&1; then
##: ucf
/usr/share/${package_name}/configuration
/etc/${package_name}.conf
##:fi
### We could also do this on the fly. The
following is from Tore
### Anderson:
#. /usr/share/debconf/confmodule
### find out what the user answered.
# db_get foo/run_on_boot
# run_on_boot=$RET
# db_stop
### safely create a temporary file to generate
our suggested
### configuration file.
# tempfile=`tempfile`
# cat << _eof > $tempfile
### Configuration file for Foo.
### this was answered by you, the user in a
debconf dialogue
# RUNONBOOT=$run_on_boot
### this was not, as it has a sane default
value.
# COLOUROFSKY=blue
#_eof
### Note that some versions of debconf do not
release stdin, so
### the following invocation of ucf may not
work, since the stdin
### is never coneected to ucfr.
### now, invoke ucf, which will take care of
the rest, and ask
### the user if he wants to update his file,
if it is modified.
#ucf $tempfile /etc/foo.conf
### done! now we'll just clear up our cruft.
#rm -f $tempfile
