Server start / restart

FreeBSD / UNIX platform, MySQL ver.4.0.16
Prob. of growing /tmp file, solved by introducing a cron job to clean up
the folder intermittently. Prob.solve but new one created - mysql socket
wiped out. Could not restart the server with all the standard methods.
Complained of other running processes. Killed the orphaned processes
runining. But still can't restart.

So can't do a dump or any other back up action, so created a tar file of
the data etc. Now I wanted to try an upgrade to a newer version but
concerned about ability to restore data from the tarball.

Does anyone have any idea of how can effect a restart before running to
do an Upgrade?

Thanks

Try rebooting the FreeBSD server host.

Point taken - in full agreement,
Changed location of socket to its own dedicated location ==>
/usr/local/var/mysql

Error message
ERROR 2002: Can't connect to local MySQL server through socket
'/usr/local/var/mysql' (38)
current message becaused of changes made to /etc/my.cnf file for new
location. Identical message when the SNAFU occurrred, but with /tmp instead

Likely or unlikely? Shouldn't all the file permission be retained in
tarball, I do expect redo GRANT PRIVILLEGES

Well not *sockets* but many session and temp files, so a rm * in the
cron file removed it

Yes, I am asumming that it needed the absolute path to the socket
directory rather than to the socket itself. Although, I changed this in
the /etc/my.cnf file and later did a compilation to vers 5.0.18
Here is the config used.

../configure CFLAGS="-O3" CXX=gcc CXXFLAGS="-O3 -felide-constructors
-fno-exceptions -fno-rtti" --prefix=/usr/local/mysql --enable-assembler
--enable-thread-safe-client --enable-local-infile
--with-unix-socket-path=/usr/local/var/mysql --with-mysqld-user=mysql
--with-openssl --with-big-tables --with-archive-storage-engine
--with-csv-storage-engine --localstatedir=/usr/db/mysql

**** "--with-unix-socket-path" ??? led to the directory assumption

Anyway used both approaches, but neiher solved the problem




Error!!!???

On Running
mysql_install_db ==>

Neither host 'econn' and 'localhost' could not be looked up with
/usr/local/bin/resolveip
Please configure the 'hostname' command to return a correct hostname.
If you want to solve this at a later stage, restart this script with
the --force option

but the hostname and at the very least localhost is OK they are set in
the /etc/rc.conf and /etc/hosts files

[Caveat - the hostname entry has the domain extension '*.com',
hostname -s removes the extension]

so I used the --force option then
mach1# pwd
/usr/local/mysql/bin
mach1# mysqld_safe &
[1] 3213
mach1# Starting mysqld daemon with databases from /var/db/mysql
060126 06:42:01 mysqld ended
Then tried
mach1# mysqladmin version
mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket
'/usr/local/var/mysql' (38)'
Check that mysqld is running and that the socket:
'/usr/local/var/mysql' exists!

It does exist w/ permissons of drwxrwxrwt

Any suggestions?
