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
            alias          backup ; Long name of the group
            }

#cd /usr/local/nagios/etc/server && vim 10.1.13.213.cfg

define host{

use linux-server ; Name of host template to use

; This host definition will inherit all variables that are defined

hostgroups Servers

; in (or inherited by) the linux-server host template definition.

host_name 10.1.13.213

alias backup

address 10.1.13.213

}

define service{

use generic-service

host_name 10.1.13.213

service_description Ping

check_command check_ping!100.0,20%!150.0,60%

}

define service{
