Nagios Monitoring Platform Setup-Installation Chapter

First, the server-side installation:

1 , build on the service side Lamp Environment

Yum install-y httpd php

2 , server-side installation Nagios Main program

Useradd-s/sbin/nologing

./configure--prefix=/usr/local/nagios--with-command-group=nagios

./configure when Perl command not found is found to install Perl this package, or make all will be error yum install-y perl

Make all

Make install, makeinstall-init;make install-config;make install-commandmode; make install-webconf

3 , server-side installation Nagios-plugins plug-in, monitoring with

./configure--prefix=/usr/local/nagios--with-nagios-user=nagios--with-nagios-group=nagios

make&& make Install

4 , server-side installation Nrpe, communication with the client

./configure--enable-ssl--with-ssl-lib

Make all

Makeinstall-plugin && make Install-daemon && makeinstall-daemon-config

Chown-rnagios:nagios/usr/local/nagios

5 , Nagios access control settings

Htpasswd-c/usr/local/nagios/etc/htpasswd.users Nagiosadmin

Enter the password two times, the login page will use this password

6 , restart Nagios httpd service

Use commands before restarting Nagios

/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg , no problem with detection, restart again

/etc/init.d/nagios Restart; /ETC/INIT.D/HTTPD restart

Second, the client installation:

1 , installation Nagios-plugins

Useradd-s/sbin/nologing Nagios

./configure –prefix=/usr/local/nagios

Make

Makeinstall

2 , installation Nrpe

./configure--enable-ssl--with-ssl-lib

Make all

Makeinstall-plugin && make Install-daemon && makeinstall-daemon-config

chown-rnagios:nagios/usr/local/nagios/

To start the client Nrpe command

/usr/local/nagios/bin/nrpe-c/usr/local/nagios/etc/nrpe.cfg-d

3 , client Nrpe settings

Vi/usr/local/nagios/etc/nrpe.cfg

Add the Nagios server-side IP address after the allowed_hosts=127.0.0.1 field

; server_address=127.0.0.1 This field do not change, keep the state of comments, Nrpe need to open the service on 0.0.0.0:5666

Iii. 6 steps for the Nagios server to monitor a client

1 , install Nrpe,nagios-plugins on both the server side and the client

2 , modify the allowed IP (IP on the server) in the client-defined monitoring project

3 , start the server side, Nrpe the client, start the command /usr/local/nagios/bin/nrpe-c/usr/local/nagios/etc/nrpe.cfg–d

After the client starts, it can execute the command/usr/local/nagios/libexec/check_nrpe-h 127.0.0.1 in the native machine, to detect, if the Nrpe version appears, the Nrpe on behalf of the machine is OK

/usr/local/nagios/libexec/check_nrpe–h Peer IP, to detect Nrpe communication is not good

4 , define the Check_nrpe command in server-side commands.cfg:

Define Command{

Command_name Check_nrpe

Command_line $USER 1$/check_nrpe-h $HOSTADDRESS $-c$arg1$

}

5 , in the server-side IP-corresponding configuration file, add the items that need to be monitored:

Define Service{

Use Local-service host_name 192.168.1.12

Service_description Sda1_monitor

Check_command Check_nrpe!check_u

Notifications_enabled 1

}

6 , in the server's main configuration file, refer to an IP corresponding configuration file, that is, in/usr/local/nagios/et/nagios.cfg about 35 lines in the location to add such a line:

cfg_file=/usr/local/nagios/etc/objects/192.168.223.132.cfg , or

cfg_dir=/usr/local/nagios/etc/192.168.223.0/ , the line above refers to a configuration file, and the following line refers to all of the configuration files in a directory
