Nagios Construction and configuration----(medium)

The previous article has written about the state of the Nagios monitoring machine we've arranged, so let's look at the configuration of the Nagios monitoring server state. As for why this configuration, we can go to Baidu under the next look

Remote server is monitored using the Nrpe plug-in.

Remote server Configuration

1, compile and install Nagios-plugin, provide the command to check the status of the server. These commands can be/usr/local/nagios/libexec/under the

The commands in the red box are some of the basic commands we use in our experiments. View command help, such as Check_http--help

TAR-ZXVF nagios-plugins-2.0.3.tar.gz-c/usr/src///Unpacking
cd/usr/src/nagios-plugins-2.0.3/

2, create the required users and groups,

Useradd Nagios
Groupadd Nagcmd
Usermod-ag Nagcmd Nagios
./configure--with-nagios-user=nagios--with-nagios-group=nagcmd

Make && make install

3, install Nrpe

TAR-ZXVF nrpe-2.12.tar.gz-c/usr/src/
cd/usr/src/nrpe-2.12/
Ls
./configure
Make && make install
Make Install-plugin
Make Install-daemon
Make Install-daemon-config

3, configure the Nrpe configuration file (at this point to/usr/local/nagios/libexec/under the view that you can see the Check_nrpe command

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

The name of the command in the note, and so on our server-side configuration needs to use

4, monitored server allows monitoring server to monitor itself

Vim/etc/xinetd.d/nrpe

5, if you start Nrpe (temporary service, need to restart the XINETD service) service, we can not see the Nrpe process. We'll first define the port 5666 under which it works.

Vim/etc/services

6, by this, we have been configured to monitor the end of the configuration has been completed. You can restart the XINETD service and load the Nrpe service.
