Addnagiosfornagiossystem:
#useraddnagios–s/sbin/nologin–gnagios
InstallnagisoServer:
Apache
PHP
要先安装gd-devel否则不会生成statusmap.cgi
#cd/data
#mkdir/data/nagios
#tarzvxfnagios-3.2.3.tar.gz–C/data/nagios
#cd/data/nagios
#./configure--prefix=/usr/local/nagios--with-nagios-user=nagios--with-nagiso-group=nagios

#./configure--prefix=/usr/local/nrpe
#make
#makeinstall
#makeinstall-xinetd
ConfigNRPE
#vi/etc/xinetd.d/nrpe
如下:
servicenrpe
{
flags=REUSE
socket_type=stream
port=5666
wait=no
user=nagios
group=nagios
server=/usr/local/nrpe/bin/nrpe
server_args=-c/usr/local/nrpe/etc/nrpe.cfg--inetd
log_on_failure+=USERID
disable=no
only_from=127.0.0.110.1.8.24#增加服务器地址
}
#vi/usr/local/nrpe/etc/nrpe.cfg
允许服务器访问
allowed_hosts=127.0.0.1,10.1.8.24
#vi/etc/services
在行尾增加,否则nrpe启动不了
nrpe5666/tcp#NRPE
RunNRPE
#/etc/init.d/xinetdrestart
CheckNRPE:
#netstat–tunl|grep5666
NRPE启动成功

PNP4Nagios与Nagios整合:
#vi/usr/local/nagios/etc/nagios.cfg
修改并打开下面内容:
process_performance_data=1
host_perfdata_command=process-host-perfdata
service_perfdata_command=process-service-perfdata
为了使配置文件更加明白，我将把定义主机和定义服务分别放到/usr/local/nagios/etc/hosts&/usr/local/nagios/etc/services,所以我们需要在nagios.cfg中增加如下内容:
cfg_dir=/usr/local/nagios/etc/hosts
cfg_dir=/usr/local/nagios/etc/services
#mkdir/usr/local/nagios/etc/{hosts,services}
#vi/usr/local/nagios/etc/objects/command.cfg
把相应部份修改如下:
definecommand{
command_nameprocess-host-perfdata
command_line/usr/bin/perl/usr/local/pnp4nagios/libexec/process_perfdata.pl-dHOSTPERFDATA
}
definecommand{
command_nameprocess-service-perfdata
command_line/usr/bin/perl/usr/local/pnp4nagios/libexec/process_perfdata.pl
}
#vi/usr/local/nagios/etc/objects/templates.cfg
在文件尾添加如下内容:
#AddbyHeQiang
definehost{
namehost-pnp
register0
action_url/pnp4nagios/index.php?
host=$HOSTNAME$
}
defineservice{
namesrv-pnp
register0
action_url/pnp4nagios/index.php?
host=$HOSTNAME$&srv=$SERVICEDESC$
}
让PNP4Nagios显示图形在nagios的主机中或服务中，加入host-pnp,srv-pnp,如下:
#vi/usr/local/nagios/etc/objects/localhost.cfg
definehost{
uselinux-server,host-pnp
host_namelocalhost
aliaslocalhost
address127.0.0.1
}
defineservice{
uselocal-service,srv-pnp
host_namelocalhost
service_descriptionPING
check_commandcheck_ping!
100.0,20%!
500.0,60%
}
重新启动HTTP&nagios
#/etc/init.d/httpdrestart
#/etc/init.d/nagiosrestart
删除/usr/local/pnp4nagios/share/install.php,否则不能浏览.
刷新网页，会看到如下内容，在Host&Service栏中多了这个图标：
点击图票，查看详细内容如下：
配置commands.cfg文件，增加NRPE:
#vi/usr/local/nagios/etc/objects/commands.cfg
在文件尾增加如下内容：
#AddbyHeQiang
definecommand{
command_namecheck_nrpe
command_line$USER1$/check_nrpe-H$HOSTADDRESS$-c$ARG1$
}
添加修改联系人,如下:
#vi/usr/local/nagios/etc/objects/con
