Plugins won't install through web interface.

Posted: Tue Aug 11, 2015 6:08 pm

Hello,

I found a plugin in the Nagios Exchange that I would like to use and used these instructions https://assets.nagios.com/downloads/nag ... ios-XI.pdf for installing. When I click on the 'upload' button I get an error stating that plugin couldn't install - directory permissions may be incorrect.

I found this forum chat dealing with the issue https://support.nagios.com/forum/viewto ... 784#p12030 and tried following the methods that were listed. I don't see the fixperms.sh script in /usr/local/nagiosxi/scripts/ but I tried the rest without success. Not sure if the script is the missing link to my problem.

Can you please post the results of these commands:

Code: Select all

ls -al /usr/local/nagios/libexec/
grep nagios /etc/group
Also, can you please provide us with the link to the plugin you found so we can test it uploads OK.

What version of Nagios XI are you using?

Here is the link to the plugin...https://exchange.nagios.org/directory/P ... ne/details

Nagios XI version is 2014R2.7

/etc/group doesn't have nagios as I created an LDAP group for nagios, does it need to be in /etc/group?

Below is the default groups created in the /etc/group file.

Code: Select all

nagios:x:500:nagios,apache,snmptt
nagcmd:x:501:nagios,apache,snmptt
Try and recreate that using the LDAP account and see if that fixes it for you.

I changed /etc/group but I'm still getting "Plugin could not be installed - directory permissions may be incorrect."

Try running to see if this fixes the permissions for you.

Code: Select all

cd /usr/local/nagiosxi/scripts/                                                                                                                                                 
./reset_config_perms.sh
Run the following and post the output here if it still fails.

Code: Select all

ll /usr/local/nagios
grep nag /etc/group
grep nag /etc/passwd

I still get the same error after running reset_config_perms.sh

Here is the output requested;

I created in LDAP a user nagios and groups for nagios so /etc/group and /etc/passwd would be empty.

Can you tail the Apache error log while you try to upload the plugin and post the output?

Code: Select all

tail -f /var/log/httpd/error_log
Another option is that you can use Secure Copy to copy the plugin manually to the system.
This is the folder where you copy the plugin to.

Code: Select all

/usr/local/nagios/libexec
Can you create the entries in the /etc/group file like my example to see it that fixes it?

I did add the entries to /etc/group but I still got the error.
