nagios 监控配置介绍(二）
#配置服务端监控客户端# cd objects/
# vi hosts.cfg
# Define a host for the local machine
define host{
use linux-server
host_name 1.3-samba
alias 1.3-samba
address 10.89.1.3
}
define host{
use linux-server
host_name 1.2-nagios
alias 1.2-nagios
address 10.89.1.2
}
define host{
use linux-server
host_name 1.34-web-lnmp
alias 1.34-web-lnmp
address 10.89.1.34
}
define host{
use linux-server

保存退出
检查语法，先编辑nagios文件,使出错信息显示出来
# vim /etc/init.d/nagios +183
$NagiosBin -v $NagiosCfgFile > /dev/null 2>&1; 修改为：
$NagiosBin -v $NagiosCfgFile
保存退出
检查语法，如果报错如下：
# /etc/init.d/nagios checkconfig
Checking services...
Error: There are no services defined!
Checked 0 services.
解决方法：
# vi services.cfg
define service {
use generic-service
host_name 1.3-samba
service_description Disk Partition
check_command check_nrpe!check_disk
}
再检查语法
# /etc/init.d/nagios checkconfig
Total Warnings: 1
Total Errors: 0
Things look okay - No serious problems were detected during the pre-flight check
OK.
#
如果报下面错误：
Error:Service check command 'check_nrpe' specified in service 'Disk Partition' for
host '10-client01' not defined anywhere!
则编辑commands.cfg 文件：
# vi commands.cfg
再末尾加上
# 'check_nrpe' command definition
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
注意：command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ 实际上就是使用这个命令探测：
#/usr/local/nagios/libexec/check_nrpe -H 10.89.1.3 -c check_disk
保存并退出
再检查语法
# /etc/init.d/nagios checkconfig
没有错误的情况下：
# /etc/init.d/nagios reload
Running configuration check...done.
Reloading nagios configuration...done

如果登录后提示错误：
It appears as though you do not have permission to view information for any of the hosts you requested...
If you believe this is an error, check the HTTP server authentication requirements for accessing this CGI
and check the authorization options in your CGI configuration file.
编辑 cgi.cfg
# cd ../
# vi cgi.cfg
# PHYSICAL HTML PATH
# This is the path where the HTML files for Nagios reside.This
# value is used to locate the logo images needed by the statusmap
# and statuswrl CGIs.
physical_html_path=/usr/local/nagios/share
:g/nagiosadmin/s//alvin/g #替换nagiosadmin 为 alvin，该用户是我安装的时候添加的
保存并退出
# /etc/init.d/nagios reload
