Nagios Check NRPE 和 Executing scripts 显示不同的输出

Question

When executing a script through check_nrpe and executing it from local server displays two different out puts.

Script is similar to this.

url="http://xxx.xxx.xxx.xxx:5000/v2/_catalog";
status="$(curl --write-out %{http_code} --silent --output /dev/null  $url)"

    if [ "$status" = 200 ]
    then
            echo "OK"
            exit 0
    else
            echo "Not responding.Please check."
            exit 2
    fi

When executing this script file from the local server directly it generates the following output

[root@xxxxxlibexec]$ ./check.sh 
OK

But when I execute this from the Nagios Core server through check_nrpe it generates the else block.

[root@xxxxx libexec]# ./check_nrpe -H xxx.xxx.xxx.xxx -p 5667 -c check_registry
Not responding.Please check.

The NRPE CFG command is as follows.

command[check_registry]=/usr/local/nagios/libexec/check.sh

I have tried restarting the NRPE and Nagios Core. Also double checked the permission issues.

This was due to the curl and libcurl mismatch. The nagios user can't curl properly. Downgraded the packages to be the same.
