The specific process for installing nagios on FreeBSD 7.0 is as follows:

OS:FreeBSD 7.0

Download the required software packages from http://www.nagios.org/download/

1.nagios-3.1.2.tar.gz

2.nagios-plugins-1.4.13.tar.gz

System requirements:

1. Apache

2. GCC compiler

3. GD library and development library

After the above software is installed, begin to install nagios.

1. Decompress

# tar zxvf nagios-2.5.tar.gz

two。 Establish the user running nagios:

# pw adduser nagios

# passwd nagios

3. Create a user group named nagcmd to execute external commands from the Web interface. Add both nagios and apache users to this group. You must determine which user the web server is running under, usually: apache. My server configuration is www.

# grep "^ User" / usr/local/apache2/conf/httpd.conf

# pw groupadd nagcmd

# pw usermod www-G nagcmd

# pw usermod nagios-G nagcmd

Run the Nagios configuration script and use previously opened users and user groups

#. / configure-prefix=/usr/local/nagios-with-gd-lib=/usr/local/lib-with-gd-inc=/usr/local/include-with-command-group=nagcmd

Review the options above for accuracy. If they look okay

Type 'make all' to compile the main program and CGIs.

Compile the Nagios package source code

# make all

Install the binary runtime program, initialize scripts, configure sample files, and set run directory permissions

# make install

Check the directory permissions of / usr/loca/etc/rc.d before running make install-init. My server is root:wheel. And Makefile pilot test root:root.

Modify Makefile

INIT_DIR=/usr/local/etc/rc.d

INIT_OPTS=-o root-g root

Change to:

INIT_DIR=/usr/local/etc/rc.d

INIT_OPTS=-o root-g wheel

Then run make install-init.

# make install-init

# make install-commandmode

# make install-config

Configure WEB Interfac

Install the WEB configuration file for Nagios to the conf directory of Apache. The path to http in the Makefile file is / etc/httpd/conf.d. Change it to the conf path of your own apache.

# make install-webconf

To this nagios core program installation is complete!

Customized configuration

The sample configuration files are installed in this directory / usr/local/nagios/etc by default. These sample files can be configured for Nagios to work properly with a simple modification.

Use the editor software you are good at to edit this / usr/local/nagios/etc/objects/contacts.cfg configuration file and change the EMail information in the contact definition information of the email address nagiosadmin to your EMail message to receive the alarm content.

# vi / usr/local/nagios/etc/objects/contacts.cfg

Configure WEB Interfac

Configure BASIC authentication for apache and create a nagiosadmin user to log in to the WEB interface for Nagios. Write down the login password you have set, and you will use it later.

# htpasswd-c / usr/local/nagios/etc/htpasswd.users nagiosadmin

Then modify the configuration file of apache

# vi / usr/local/apache/conf/httpd.conf

Add the following:

ScriptAlias / nagios/cgi-bin / usr/local/nagios/sbin

Options ExecCGI

AllowOverride None

Order allow,deny

Allow from all

AuthName "Nagios Access"

AuthType Basic

AuthUserFile / usr/local/nagios/etc/htpasswd.users

Require valid-user

Alias / nagios/ usr/local/nagios/share

Options None

AllowOverride None

Order allow,deny

Allow from all

AuthName "Nagios Access"

AuthType Basic

AuthUserFile / usr/local/nagios/etc/htpasswd.users

Require valid-user

After the modification, save the file and restart apache:

# / usr/local/apahce/bin/apachectl restart

Restart the Apache service for the settings to take effect.

Compile and install the Nagios plug-in

Expand the source package for the Nagios plug-in

# tar xzf nagios-plugins-1.4.13.tar.gz

# cd nagios-plugins-1.4.11

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

# make

# make install

After the installation is complete, a libexec directory will be generated in / usr/local/nagios-plugins-plugins, and you can move it all to the / usr/local/nagios directory.

# mv / usr/local/nagios-plugins-plugins/libexec/ / usr/local/nagios/

Start Nagios

Verify the sample configuration file for Nagios

# / usr/local/nagios/bin/nagios-v / usr/local/nagios/etc/nagios.cfg

Appear:

Total Warnings: 0

Total Errors: 0

Things look okay-No serious problems were detected during the pre-flight check

There is nothing wrong with the configuration file.

Start nagios

# / usr/lcoal/etc/rc.d/nagios start

Log in to the WEB interface

You can now access the WEB interface of Nagios from WEB. You need to enter your user name (nagiosadmin) and password at the prompt, which you just set. Here use the browser installed by default on the system. Use the hyperlink below.
