Hi Managers,
I have 2 questions:
I have Ds20 with OS 5.1v, I am running mysql server, and some time it
stop for that I create csh script to watch it, and if goes down restart
it.
1) The Script:
#!/bin/csh
# checks the mysql server daemon and restart if needed
# customized for Mysql on lupine Rezk Mekhael 10/2003
umask 077
set tmp=/tmp/chkmysql.$$
set manager=rezk@clunet.edu
ps ax > $tmp
if ( `grep -c "mysql" $tmp` != "0" ) then
echo "listener is running" > /dev/null
else
/sbin/rc3.d/s100mysql
echo "Mysql Server is down, starting it up" > /tmp/message.$$
/usr/bin/mail $manager < /tmp/message.$$
rm -r /tmp/message.$$
endif
rm -f $tmp
=======================================
2) This file "/sbin/rc3.d/s100mysql" contains:
cd /usr/local/mysql;
bin/safe_mysqld --user=mysql
My questions: 1) I can run this file S100mysql by hand but the script
can not run it, why?
2) Does any one have a startup script for mysql
in /sbin/rc3.d?
