[Xymon] mysql password file on centos 5, xymon client

[Mike Burger]

Leon,

 

If you installed Xymon from RPM on your CentOS 5 system, and you run
either "finger xymon" or "grep xymon /etc/passwd", you'll likely note
that the xymon user's home directory is /usr/lib/xymon. Try
creating/moving the .my.cnf there.

Hi,

I have a question.
Recently I've added a script to monitor the mysql replication.
I got it off the internet:
------------------------------------------------------------------------
------------------------------------------------------------------------
-----------------------
#!/bin/bash 


########################################################################
####################
test -e /usr/local/mysql/bin/mysql && PROG=/usr/local/mysql/bin/mysql
test -e /usr/bin/mysql && PROG=/usr/bin/mysql
MAXDRIFT=5
########################################################################
####################

MYSQLCOLOR=""
MYSQLLINE=""
HOSTIP=127.0.0.1
IPADDR=127.0.0.1
MACHINE=`uname -n`

MAXSEC=60

MYSQLUSER=root
MYSQLPORT=3306
LINE=`echo "show slave status \G" | ${PROG} -h ${HOSTIP} -u ${MYSQLUSER}
-P ${MYSQLPORT} 2>&1`
MASTERPOS=`echo $LINE | grep Read_Master_Log_Pos | awk -F
'Read_Master_Log_Pos: ' '{print $2}' | awk '{print $1}'`
SLAVEPOS=`echo $LINE | grep -i Exec_Master_Log_Pos | awk -F
'Exec_Master_Log_Pos: ' '{print $2}' | awk '{print $1}'`
SLAVEUP=`echo $LINE | grep Running | wc -l`
SLAVE_SECOND_BEHIND_MASTER=`echo $LINE | grep 'Seconds_Behind_Master:'
| awk -F 'Seconds_Behind_Master: ' '{print $2}'  | awk '{print $1}'` 
test $SLAVEUP -eq "1"  &&  DRIFT=$((${MASTERPOS} - ${SLAVEPOS}))
echo "${LINE}" | ${GREP} "Running: No" >/dev/null
if test "$?" -eq "0"
then
    MYSQLCOLOR="red"
    MYSQLLINE="`${DATE}` MYSQL Slave in error
${LINE}"
elif test ${SLAVEUP} -ne "1"
then
    MYSQLCOLOR="green"
    MYSQLLINE="`${DATE}` MYSQL Slave is Stopped
${LINE}"
elif test ${SLAVE_SECOND_BEHIND_MASTER} -ge ${MAXSEC} 
then
    MYSQLCOLOR="yellow"
    MYSQLLINE="`${DATE}` MYSQL Slave is ${DRIFT} statements behind!
${LINE}"
else
    MYSQLCOLOR="green"
    MYSQLLINE="`${DATE}` MYSQL Slave is ${DRIFT} statements behind!
${LINE}"
fi

#echo "${BB} ${BBDISP} status ${MACHINE}.mysqlslave ${MYSQLCOLOR}
${MYSQLLINE}"
${BB} ${BBDISP} "status ${MACHINE}.mysqlslave ${MYSQLCOLOR}
${MYSQLLINE}"

-----------------

To make it working, you need to create the file : ~hobbit/.my.cnf  

[mysql]
password=XXXXXXXX
[mysqlclient]
password= XXXXXXXX
[mysqladmin]
password= XXXXXXXX
[mysqlshow]
password= XXXXXXXX
[mysqldump]
password= XXXXXXXX
-------------------------------------------
chown hobbit: ~hobbit/.my.cnf
chmod 600 ~hobbit/.my.cnf


Add the section in clientlaunch.cfg

[mysqlslave]
        ENVFILE $HOBBITCLIENTHOME/etc/hobbitclient.cfg
        CMD $HOBBITCLIENTHOME/ext/mysqlslave.sh
        LOGFILE $HOBBITCLIENTHOME/logs/mysqlslave.log
        INTERVAL 5m


Restart hobbit-client.
------------------------------------------------------------------------
------------------------------------------------


as you can see, the author instructs to put the .my.cnf file with all
the passwords in the ~hobbit/.my.cnf directory.
While that went fine on the Ubuntu 12.04 server, it doesn't work on the
CentOS 5 server.
I got the xymon client.rpm from some website and it just doesn't
recognize this file no matter where I put it.
The version is 4.3.10.
the client is installed in these directories:
/etc/xymon-client
/usr/libexec/xymon-client
/usr/share/xymon-client

I also noticed that there's no /var/lib/xymon-client directory. 
The Ubuntu version was installed via apt-get and still has "hobbit"
naming. 
On CentOS client I renamed all the "hobbit" into "xymon".
If I put the pass into the script itself - it works. But I really don't
want to do that.

Any ideas?
 
Thanks,
Lenny
