上面在cacti 安装配置中已经安装，这里就不再进行安装了

centos 7 yum 安装nagios

yum install nagios

yum install nagios-plugins-all

1、tar -zxvf nagios ...tar.gz

#useradd nagios

#passwd nagios

#cd nagios..

#./configure --prefix=/usr/local/nagios

#make all

#make install

#make install-init

# make install-commandmode

#make install-config

#make install-webconf 安装到了Apache目录下conf.d目录了

#make install-exfoliation

#make install-classicui

#修改httpd.conf里的User 和Group 为nagios 改了之后cacti注意，能不能使用cacti了

2、编译安装nagios-plugins-2.0 #./configure --prefix=/usr/local/nagios

#make&&make install

3、安装nrpe，#tar –zxvf nrpe-2.9.tar.gz

#./configure –prefix=/usr/local/nagios

#make all

#make install-pluhin

#make install-daemon

#make install-daemon-config

#chown–R nagios:nagios /usr/local/nagios

#更改/usr/local/nagios/etc/cgi.cfg 里面nagiosadmin 改成nagios

#service nagios start

#service httpd start

#service mysql start

# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagios

#vim nagios/etc/objects/command.cfg 添加

define command{

command_name check_nrpe

command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -t 30

}

# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

#/usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg

被监控主机配置：

4、安装nrpe

#./configure --prefix=/usr/loca/nagios

#make all && make install-plugin && make install-daemon && make install-daemon-conig

#vim /usr/local/nagios/etc/nrpe.conf 添加监控服务器IP

allowed_hosts=127.0.0.1,10.1.13.176

#/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.conf -d 开启的端口是5666

#安装nagios-plugin

5、添加需要监控的插件和程序

#vim nrpe.conf ##例：

command[check_swap]=/usr/local/nagios/libexec/check_swap -w 50% -c 20%

6、yum install net-snmp-libs net-snmp-utils net-snmp

监控主机配置nrpe service

#mkdir server

#vim nagios.conf 添加 cfg_dir=/usr/local/nagios/etc/server

#vim /usr/local/nagios/etc/server/group.cfg

define hostgroup{

hostgroup_name Servers ; The name of the hostgroup

alias Servers ; Long name of the group

}

define hostgroup{

hostgroup_name backup ; The name of the hostgroup
