一、远程主机添加nagios用户
|
1
|
[root@yo ~]
# useradd -s /sbin/nologin nagios
|
二、安装nagios-plugins插件
|
1
2
|
[root@yo nagios-plugins-2.1.1]
# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
[root@yo nagios-plugins-2.1.1]
# make && make install
|
三、查看生成的目录文件
|
1
2
|
[root@yo nagios-plugins-2.1.1]
# ls /usr/local/nagios/
include libexec share
|
四、安装nrpe
|

|
[root@yo nrpe-2.15]
# ./configure
[root@yo nrpe-2.15]
# make all
[root@yo nrpe-2.15]
# make install-daemon
[root@yo nrpe-2.15]
# make install-daemon-config
[root@yo nrpe-2.15]
# make install-plugin
|
五、安装nrpe守护进程的服务xinetd
|
1
2
|
[root@yo nrpe-2.15]
# make install-xinetd
/usr/bin/install
-c -m 644 sample-config
/nrpe
.xinetd
/etc/xinetd
.d
/nrpe
|
六、打开/etc/xinetd.d/nrpe文件，修改添加服务端IP
|
1
|
only_from = 127.0.0.1 localhost 192.168.1.21
|
七、添加nrpe守护进程端口号
|
1
2
|
[root@yo nrpe-2.15]
# vim /etc/services
nrpe 5666
/tcp
#nrpe
|
八、安装xinetd软件包，并重启xinetd服务
|
1
2
3
4
|
[root@yo nrpe-2.15]
# yum -y install xinetd
[root@yo nrpe-2.15]
# /etc/init.d/xinetd restart
Stopping xinetd: [FAILED]
Starting xinetd: [ OK ]
|
九、查看监听端口和nrpe进程有没有起来
|
1
2
|
[root@yo nrpe-2.15]
# netstat -ntlp |grep 5666
tcp 0 0 :::5666 :::* LISTEN 73351
/xinetd
|
|
1
2
|
[root@yo nrpe-2.15]
# netstat -at | grep nrpe
tcp 0 0 *:nrpe *:* LISTEN
|
十、在远程主机运行check_nrpe测试有没有安装或配置成功
|

|
[root@yo nrpe-2.15]
# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.15
[root@yo nrpe-2.15]
# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 -c check_users
USERS OK - 5
users
currently logged
in
|
users
=5;5;10;0
[root@yo nrpe-2.15]
# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1 -c check_load
OK - load average: 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;
|
|
1

|
[root@yo nrpe-2.15]
# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.15
[root@yo nrpe-2.15]
# /usr/local/nagios/libexec/check_nrpe -H localhost -c check_users
USERS OK - 5
users
currently logged
in
|
users
=5;5;10;0
|
十一、以下是在服务端测试
|
1

|
[root@www ~]
# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.250
NRPE v2.15
[root@www ~]
# /usr/local/nagios/libexec/check_nrpe -H 192.168.1.250 -c check_users
USERS OK - 5
users
currently logged
in
|
users
=5;5;10;0
|
十二、服务端添加hosts.cfg和services.cfg两个文件，作为远程主机的监控配置文件
|

|
[root@www ~]
# vim /etc/nagios/nagios.cfg
cfg_file=
/etc/nagios/objects/hosts
.cfg
cfg_file=
/etc/nagios/objects/services
.cfg
[root@www ~]
# touch /etc/nagios/objects/hosts.cfg
[root@www ~]
# touch /etc/nagios/objects/services.cfg
|
十三、配置services.cfg文件
