　　环境、资源准备

　　gcc-3.4.6-sol10-x86-local.gz

　　libiconv-1.11-sol10-x86-local.gz

　　libintl-3.4.0-sol10-x86-local.gz

　　make-3.81-sol10-x86-local.gz

　　openssl-0.9.8h-sol10-x86-local.gz

　　httpd-2.2.4.tar.gz

　　nagios-3.0.3.tar.gz

　　nagios-plugins-1.4.11.tar.gz

　　nrpe-2.12.tar.gz

#p#

　　1.安装Nagios

　　# groupadd nagios  
 
　　# useradd -g nagios -d /usr/local/nagios nagios  
 
　　# gunzip ./nagios-3.0.6.tar.gz  
 
　　# tar xvf ./nagios-3.0.6.tar.gz  
 
　　# cd ./nagios-3.0.6.tar.gz  
 
　　# ./configure --prefix=/usr/local/nagios --with-nagios-user=nagios \

　　--with-nagios-group=nagios --with-gd-lib=/usr/sfw/lib \

　　--with-gd-inc=/usr/sfw/include

　　# make all  
 
　　# make fullinstall  
 
　　# make install-config

　　2.安装openssl

　　# gunzip ./openssl-0.9.8j-sol10-sparc-local.gz  
 
　　# pkgadd -d ./openssl-0.9.8j-sol10-sparc-local  
 
　　# export LD_LIBRARY_PATH=/usr/local/ssl/lib:$LD_LIBRARY_PATH

　　3.安装Nagios Plugins

　　# gunzip ./nagios-plugins-1.4.13.tar.gz  
 
　　# tar xvf ./nagios-plugins-1.4.13.tar  
 
　　# cd nagios-plugins-1.4.13  
 
　　# ./configure --without-mysql --prefix=/usr/local/nagios --with-openssl=/usr/local/ssl  
 
　　# make  
 
　　# make install  
 
　　# make clean  
 
　　# chown -R nagios:nagios /usr/local/nagios/libexec

　　4.配置Apache

　　在/etc/apache2/httpd.conf文件追加如下内容

　　#setting for nagios

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

　　AuthType Basic

　　Options ExecCGI

　　AllowOverride None

　　Order allow,deny

　　Allow from all

　　AuthName "Nagios Access"

　　AuthUserFile /usr/local/nagios/etc/htpasswd

　　Require valid-user

　　Alias /nagios /usr/local/nagios/share

　　AuthType Basic

　　Options None

　　AllowOverride None

　　Order allow,deny

　　Allow from all

　　AuthName "nagios Access"

　　AuthUserFile /usr/local/nagios/etc/htpasswd

　　Require valid-user

#p#

　　5.生成登录用户和验证口令

　　# /usr/apache2/bin/htpasswd -c /usr/local/nagios/etc/htpasswd

　　此处的user_name为登录Nagios Web应用需要输入的用户名www.britepic.org

　　按照提示输入要设置的口令即可

　　配置/usr/local/nagios/etc/cgi.cfg，添加用户edison

　　................. .................

　　# SYSTEM/PROCESS INFORMATION ACCESS

　　# This option is a comma-delimited list of all usernames that

　　# have access to viewing the Nagios process information as

　　# provided by the Extended Information CGI (extinfo.cgi). By

　　# default, *no one* has access to this unless you choose to

　　# not use authorization. You may use an asterisk (*) to

　　# authorize any user who has authenticated to the web server.

　　authorized_for_system_information=nagiosadmin,edison

　　# CONFIGURATION INFORMATION ACCESS

　　# This option is a comma-delimited list of all usernames that

　　# can view ALL configuration information (hosts, commands, etc).

　　# By default, users can only view configuration information

　　# for the hosts and services they are contacts for. You may use

　　# an asterisk (*) to authorize any user who has authenticated

　　# to the web server.

　　authorized_for_configuration_information=nagiosadmin,edison

　　# SYSTEM/PROCESS COMMAND ACCESS

　　# This option is a comma-delimited list of all usernames that

　　# can issue shutdown and restart commands to Nagios via the

　　# command CGI (cmd.cgi). Users in this list can also change

　　# the program mode to active or standby. By default, *no one*

　　# has access to this unless you choose to not use authorization.

　　# You may use an asterisk (*) to authorize any user who has

　　# authenticated to the web server.

　　authorized_for_system_commands=nagiosadmin,edison

　　# GLOBAL HOST/SERVICE VIEW ACCESS

　　# These two options are comma-delimited lists of all usernames that

　　# can view information for all hosts and services that are being

　　# monitored. By default, users can only view information

　　# for hosts or services that they are contacts for (unless you

　　# you choose to not use authorization). You may use an asterisk (*)

　　# to authorize any user who has authenticated to the web server.

　　authorized_for_all_services=nagiosadmin,edison

　　authorized_for_all_hosts=nagiosadmin,edison

　　# GLOBAL HOST/SERVICE COMMAND ACCESS

　　# These two options are comma-delimited lists of all usernames that

　　# can issue host or service related commands via the command

　　# CGI (cmd.cgi) for all hosts and services that are being monitored.

　　# By default, users can only issue commands for hosts or services

　　# that they are contacts for (unless you you choose to not use

　　# authorization). You may use an asterisk (*) to authorize any

　　# user who has authenticated to the web server.

　　authorized_for_all_service_commands=nagiosadmin,edison

　　authorized_for_all_host_commands=nagiosadmin,edison

　　6.启动Nagios

　　Nagios的启动程序是/usr/local/nagios/bin/nagios

　　# ./nagios --help

　　Nagios 3.0.3

　　Last Modified: 06-25-2008

　　License: GPL

　　Usage: ./nagios [options]

　　Options:

　　-v, --verify-config Verify all configuration data

　　-s, --test-scheduling Shows projected/recommended check scheduling and other

　　diagnostic info based on the current configuration files.

　　-x, --dont-verify-paths Don't check for circular object paths - USE WITH CAUTION!

　　-p, --precache-objects Precache object configuration - use with -v or -s options

　　-u, --use-precached-objects Use precached object config file

　　-d, --daemon Starts Nagios in daemon mode, instead of as a foreground process

　　Visit the Nagios website at http://www.nagios.org/ for bug fixes, new

　　releases, online documentation, FAQs, information on subscribing to

　　the mailing lists, and commercial support options for Nagios.

　　首先通过-v选项验证配置文件是否正确

　　# cd /usr/lcoal/nagios/bin

　　# ./nagios -v ../etc/nagios.cfg

　　Nagios 3.0.3

　　Last Modified: 06-25-2008

　　License: GPL

　　Reading configuration data...

　　Running pre-flight check on configuration data...

　　Checking services...

　　.........................................................

　　.............................................

　　Total Warnings: 0

　　Total Errors: 0

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

　　如果没有错误，就可以启动它了。

　　# cd /usr/local/nagios/bin

　　# ./nagios -d /usr/local/nagios/etc/nagios.cfg

　　nagios web界面提示

　　It appears as though you do not have permission to view information for any of the services you requested...

　　打开cgi.cfg配置文件，里面有个参数:

　　use_authentication=1

　　为了保障系统的安全性，nagios设置了这个参数，默认为1,改为0即可

　　查看/usr/local/nagios/var/nagios.log日志文件，观察启动是否正常。

　　在IE浏览器中查看监控情况。

　　点击左边导航栏的 Host Detail

通过文章的介绍，我们清楚的知道了Solaris下的nagios监控系统的全过程，希望大家喜欢!
