Nagios是一个系统和网络监控软件，它可以监测所指定的主机和服务，并在出现问题以及问题恢复后发出报警。Nagios最早是被设计运行于Linux环境下的，但在大多数Unix操作系统下也可以使用。同时它是一个开源软件，我们可以免费获得它的源码，和使用它。Nagios是个不错的系统监控软件，www.britepic.org应用的范围也比较广泛。
本文将介绍Nagios在Solaris10操做系统下的安装过程，其中包括，源码的编译、安装；Apache的安装、Nagios CGI的配置；Nagios监控配置等。
本文参考了Nagios的官方文档和Nagios社区的文章，以及互联网上其他人的相关帖子。
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
gd-2.0.35-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
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
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

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

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。
