make install-commandmode
make install-webconf
9.cp -R contrib/eventhandlers/ /usr/local/nagios/libexec/
10.chown -R nagios:nagios /usr/local/nagios/libexec/eventhandlers/
11. /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
12./etc/init.d/nagios start
13./etc/init.d/httpd start
14.vim /etc/httpd/conf/httpd.conf
User nagios
Group nagios
ServerName 192.168.1.2 #本机IP
15./etc/init.d/httpd restart
16.htpasswd -c/usr/local/nagios/etc/htpasswd.users nagiosadmin
17.cd nagios-plugins-1.4.16
18../configure--with-nagios-user=nagios --with-nagios-group=nagios
make && make install
19./etc/init.d/iptables stop
20.setenforce 0
21.登陆地址：http://192.168.1.2/nagios/
用户名/密码：nagiosadmin/nagios
IP为安装nagios机器IP，密码是用htpasswd生成的密码
安装nrpe监控远程
在被监控的主机上操作
1.tar -zxf nagios-plugins-1.4.16.tar.gz
tar -zxf nrpe-2.14.tar.gz
2.yum install gcc
3.yum install opensslopenssl-devel
4.useradd nagios
5.mkdir /usr/local/nagios
6.cd nagios-plugins-1.4.16
7. ./configure--prefix=/usr/local/nagios/
make
make install
8.cd nrpe-2.14
9../configure --prefix=/usr/local/nagios/
make all
make install-plugin
make install-daemon
make install-daemon-config
make install-xinetd
make install
10.vim /etc/xinetd.d/nrpe
only_from = 127.0.0.1 192.168.1.2 #监控机器IP
11.vim /etc/services 添加
nrpe 5666/tcp
12./etc/init.d/xinetd restart
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
13.在本机验证nrpe是否安装成功
[root@tvie3etc]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.14
14.将check_nrpe传到监控机器上
scp check_nrpe [email protected]:/usr/local/nagios/libexec/
15.vim /usr/local/nagios/etc/nrpe.cfg
allowed_hosts=127.0.0.1,192.168.1.2
16./etc/init.d/iptables stop
17.setenforce 0
在监控机器上执行
18.验证nrpe是否正常工作
[root@tvie2etc]# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.3 -c check_load
OK - loadaverage: 0.00, 0.00, 0.00|load1=0.000;15.000;30.000;0;load5=0.000;10.000;25.000;0; load15=0.000;5.000;20.000;0;
19.定义nrpe命令
vim /usr/local/nagios/etc/objects/commands.cfg
define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c$ARG1$
}
20.新添加一台被监控的主机，并加入到组中
vim /usr/local/nagios/etc/objects/localhost.cfg
define host{
use linux-server
host_name 192.168.1.3
alias 192.168.1.3
address 192.168.1.3
}
define hostgroup{
hostgroup_name linux-servers
alias Linux Servers
members localhost,192.168.1.3
}
21.为添加的主机添加被监控的服务
vim /usr/local/nagios/etc/objects/localhost.cfg
define service{
use local-service
host_name 192.168.1.3
service_description load
check_command check_nrpe!check_load
notifications_enabled 0
}
define service{
use local-service
host_name 192.168.1.3
service_description Total_procs
check_command check_nrpe!check_total_procs
notifications_enabled 0
}
22./etc/init.d/nagios restart
23.在web页面观看效果
