Nagios monitoring network server and network service installation

NagiosThe installation is relatively simple, and the complex is the setting of settings and configuration parameters. But you need to relax. After all, we need to fix it, right? Let's get started:

1: Get the latest installation package

:Http://www.nagios.org/download

2: log on to the server as root

The latest version is 2.5:

1) nagios, Version 2.5:

Fetch http://superb-west.dl.sourceforge.net/sourceforge/nagios/nagios-2.5.tar.gz

Or

Wget http://superb-west.dl.sourceforge.net/sourceforge/nagios/nagios-2.5.tar.gz

2) obtain the nagios plugin version 1.4.3:

Http://surfnet.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.3.tar.gz

3) obtain the image library file:

Http://dl.sf.net/nagios/imagepak-base.tar.gz

4) NRPE, version 2.5.2

Http://ufpr.dl.sourceforge.net/sourceforge/nagios/nrpe-2.5.2.tar.gz

5) NSCA, version 2.6

Http://kent.dl.sourceforge.net/sourceforge/nagios/nsca-2.6.tar.gz

3: switch to the root user

Sudo su

4: Extract

Tar zxvf nagios-2.5.tar.gz

5. Create a user running nagios

Adduser nagios

6: Create a folder for installing nagios

Make the folder owner nagios: nagios

Mkdir/usr/local/nagios

Chown nagios. nagios/usr/local/nagios

7. Confirm the web Server user

Some commands may be executed through the web interface. You must determine which user the web server runs, usually apache:

Grep "^ User"/usr/local/apache2/conf/httpd. conf

8: Create a command file group

This new group will include apache users and nagios users.

 
 

  
  
pw groupadd nagcmd    
  
  
pw usermod apache -G nagcmd    
  
  
pw usermod nagios -G nagcmd    
  
  
----------------------------------   
  
  
cat /etc/group   
  
  
nagcmd:*:9007:apache,nagios   
  
  
----------------------------------

make all    
  
  
make install   
 
 

After the installation is complete, a libexec directory will be generated in/usr/local/nagios-plugins, and all the directories will be moved to the/usr/local/nagios directory.

Mv/usr/local/nagios-plugins/libexec // usr/local/nagios/

11: Installation of imagepak-base.tar.gz

Tar-xvzf imagepak-base.tar.gz

Decompress the package to the base directory.

Mv base/usr/local/nagios/share/images/logos/

The nagios installation process ends now. You must be careful and accurate in your operations. If you are not familiar with nagios, we recommend that you first take a look at the nagios network server monitoring and network service concepts to make the service configuration more smooth. If your host is ready for the above work, we will start to configure nagios. For more information, see troubleshooting and configuration.
