【Nagios】nagios服务器添加监控远程Linux主机
一、远程主机添加nagios用户
1
|
[[email protected] ~] # useradd -s /sbin/nologin nagios
|
二、安装nagios-plugins插件
1
2
|
[[email protected] nagios-plugins-2.1.1] # ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios --with-nagios-group=nagios
[[email protected] nagios-plugins-2.1.1] # make && make install
|
三、查看生成的目录文件
1
2
|
[[email protected] nagios-plugins-2.1.1] # ls /usr/local/nagios/
include libexec share |
四、安装nrpe

|
[[email protected] nrpe-2.15] # ./configure
[[email protected] nrpe-2.15] # make all
[[email protected] nrpe-2.15] # make install-daemon
[[email protected] nrpe-2.15] # make install-daemon-config
[[email protected] nrpe-2.15] # make install-plugin
|
五、安装nrpe守护进程的服务xinetd
1
2
|
[[email protected] 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
|
[[email protected] nrpe-2.15] # vim /etc/services
nrpe 5666 /tcp #nrpe
|
八、安装xinetd软件包,并重启xinetd服务

|
[[email protected] nrpe-2.15] # yum -y install xinetd
[[email protected] 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
|
[[email protected] nrpe-2.15] # netstat -ntlp |grep 5666
tcp 0 0 :::5666 :::* LISTEN 73351 /xinetd
|
1
2
|
[[email protected] 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

[[email protected] nrpe-2.15] # /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.15 [[email protected] 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
[[email protected] 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; |

[[email protected] nrpe-2.15] # /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.15 [[email protected] 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

[[email protected] ~] # /usr/local/nagios/libexec/check_nrpe -H 192.168.1.250
NRPE v2.15 [[email protected] ~] # /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

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