2、nagios安装

1) Create Account Information

以root用户登录，创建nagios账户

[root@cactiez Nagios]# useradd -m nagios

[root@cactiez Nagios]# passwd nagios

Create a new nagcmd group for allowing external commands to be submitted through the web interface.Add both the nagios user and the apache user to the group.

[root@cactiez Nagios]# groupadd nagcmd

[root@cactiez Nagios]# usermod -a -G nagcmd nagios

[root@cactiez Nagios]# usermod -a -G nagcmd apache

2) Compile and Install Nagios

[root@cactiez Nagios]# tar -zxvf nagios-3.2.1.tar.gz

[root@cactiez Nagios]# cd nagios-3.2.1

[root@cactiez nagios-3.2.1]# ./configure --with-command-group=nagcmd

[root@cactiez nagios-3.2.1]# make all && make install &&make install-init&&\

make install-config&&make install-commandmode

[root@cactiez nagios-3.2.1]# vi /usr/local/nagios/etc/objects/contacts.cfg 编辑下行：如图

3) Configure the Web Interface

[root@cactiez nagios-3.2.1]# make install-webconf

Create a nagiosadmin account for logging into the Nagios web interface. Remember the password you assign to this account - you’ll need it later.

[root@cactiez nagios-3.2.1]# htpasswd –c usr/local/nagios/etc/htpasswd.users nagiosadmin

Restart Apache to make the new settings take effect.

[root@cactiez nagios-3.2.1]# service httpd restart

4) Compile and Install the Nagios Plugins

[root@cactiez Nagios]# tar -zxvf nagios-plugins-1.4.15.tar.gz

[root@cactiez Nagios]# cd nagios-plugins-1.4.15

[root@cactiez nagios-plugins-1.4.15]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios

[root@cactiez nagios-plugins-1.4.15]# make && make install

5) Start Nagios

Add Nagios to the list of system services and have it automatically start when the system boots.

[root@cactiez nagios-plugins-1.4.15]# chkconfig --add nagios

[root@cactiez nagios-plugins-1.4.15]# chkconfig nagios on

Verify the sample Nagios configuration files.

[root@cactiez nagios-plugins-1.4.15]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

[root@cactiez nagios-plugins-1.4.15]# service nagios restart

3、NDOUtils安装

[root@cactiez Nagios]# tar -zxvf ndoutils-1.4b7.tar.gz

[root@cactiez Nagios]# cd ndoutils-1.4b7

[root@cactiez ndoutils-1.4b7]# ./configure --with-mysql-inc=/usr/include/mysql --with-mysql-lib=/usr/lib/mysql --enable-mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios

[root@cactiez ndoutils-1.4b7]# make

copy the sample NDOUtils config files to the Nagios etc/ directory:

[root@cactiez ndoutils-1.4b7]# cd config

[root@cactiez config]# cp ndo2db.cfg ndomod.cfg /usr/local/nagios/etc/

In order to install the NDOUtils components on your system, you'll need to copy the compiled binaries into your Nagios binary directory (usually /usr/local/nagios/bin)

[root@cactiez ndoutils-1.4b7]# cd src/

[root@cactiez src]# cp ndomod-3x.o ndomod.o

[root@cactiez src]# cp ndo2db-3x ndo2db

[root@cactiez src]# cp file2sock log2ndo ndo2db ndomod.o /usr/local/nagios/bin/

1、 Cacti Plugin Architecture 安装

[root@cactiez Nagios]# unzip cacti-plugin-0.8.7e-PA-v2.6.zip

[root@cactiez Nagios]# cd cacti-plugin-arch/

[root@cactiez cacti-plugin-arch]# cp cacti-plugin-0.8.7e-PA-v2.6.diff pa.sql /var/www/html/

[root@cactiez cacti-plugin-arch]# cd /var/www/html/

[root@cactiez html]# patch -p1 -N < cacti-plugin-0.8.7e-PA-v2.6.diff

import the pa.sql file into your mysql database

[root@cactiez html]# mysql -u root -p cacti<pa.sql

4、NPC安装

安装php-json

[root@cactiez Nagios]# tar jxvf php-json-ext-1.2.1.tar.bz2

[root@cactiez Nagios]# cd php-json-ext-1.2.1

[root@cactiez php-json-ext-1.2.1]# phpize

[root@cactiez php-json-ext-1.2.1]# ./configure &&make &&make install

[root@cactiez php-json-ext-1.2.1]# echo "extension=json.so">/etc/php.d/json.ini

安装NPC

[root@cactiez Nagios]# tar zxvf npc-2.0.4.tar.gz

[root@cactiez Nagios]# mv npc/ /var/www/html/plugins

[root@cactiez Nagios]# vi /var/www/html/include/global.php添加如下行：如图

Install the plugin in Cacti

Go to 控制台 -> 插件管理 -> Uninstalled
Click the Install link under the npc section
Next, click the Installed tab
To enable NPC click the Enable link under the npc section

Next, there are a few NPC settings to add/update. click the Console tab -> Settings (under Configuration heading) -> NPC tab.

Remote Commands

Check the checkbox to enable remote commands. At the moment this is system wide so all users that can access NPC will be able to execute commands.

Nagios Command File Path

Add the path to the nagios command file. It will be something like /usr/local/nagios/var/rw/nagios.cmd

Nagios URL

The URL to the Nagios web interface is used to get access to the status map and reporting CGI's. You can also access the Nagios UI by clicking the "Nagios" link in the left hand "Navigation" pane in NPC.

Set the date and time format to your liking.
