Common errors in Nagios

First, the start times wrong

"Starting Nagios:this account isn't currently available"

Workaround:

Modify/ETC/PASSWD

Change the/sbin/nologin into/bin/bash

Second, Nagios installed, Web Access to the following error:

You do not have permission to view information for any host.

Check the HTTP server's access rights settings for this CGI.

Solution:

Vi/usr/local/nagios/etc/cgi.cfg

Change the value of Use_authentication to 0.

Use_authentication=0

and restart the Nagios service.

Service Nagios Restart

It is also possible:

Hostname and service_description in the configuration file use Chinese.

Advise hostname and service_description not to use Chinese

Third, the visit appears garbled

Typically, the Apache configuration file has a coding problem

Workaround:

Vim/usr/local/apache2/conf/httpd.conf

Finally add Adddefaultcharset utf-8

Four, appears the requested url/nagios/cgi-bin/statusmap.cgi is not found on this server error

Workaround:

Determine the installation Gd-devel package

And then back to the extract directory,

#make Clean

Recompile installation

#./configure--with-gd-lib=/usr/lib--with-gd-inc=/usr/include

Next

#./configure--with-command-group=nagcmd

#make all;

make install;

Make install-init;

Make install-config;

Make Install-commandmode;

Makeinstall-webconf

V. To view the Nagios.log log, the following error occurred:

Ndomod:could not Open Data sink! I ' ll keep trying, but some output may get lost ...

Solution Idea:

# vim/usr/local/nagios/etc/ndo2db.cfg

Ndo2db_user=nagios

Ndo2db_group=nagcmd

Note that the second, ndo2db group, is nagcmd. Because the previous system plus user Nagios is the Nagcmd group.
