Doubts Regarding check_mysql plugin


We have installed nagios-2.8 in our fc6 system with official plugins( nagios1.4.11) except check_mysql plugin. So we have iinstallled check_mysql plugin alone from the nagiosplugin website. All the plugins are in the location /usr/local/nagios/libexec/libexec.
We have no problem with other plugins. But when executing check_mysql plugin, we are facing the following error:

[root@localhost libexec]# ./check_mysql
bash: ./check_mysql: cannot execute binary file

CFG files:


‘check_mysql’ command definition

We have already installled mysql-server using yum. Kindly help us to solve this problem.
