安装系统：redhat linux as 4 2.6.9
:nagios 监控安装配置
准备软件：nagios-2.6.tar.gz nagios-plugins-1.4.9 .tar.gz
Linux 安装完系统后默认是可以发送邮件的。（我在安装系统的时候开启了mail服务，以及安装了开发环境软件）
（1）：添加nagios用户及组
[root@linux etc]# groupadd nagios
[root@linux etc]# useradd -g nagios -d /usr/local/nagios -s /bin/false nagios
（2）：解压，安装nagios
[root@linux nagios]# tar zxvf nagios-2.6.tar.gz
[root@linux nagios-2.6]# ./configure --prefix=/usr/local/nagios
[root@linux nagios-2.6]# make all
[root@linux nagios-2.6]# make install
[root@linux nagios-2.6]# make install-init
[root@linux nagios-2.6]# make install-commandmode
[root@linux nagios-2.6]# make install-config
安装nagios的插件
[root@linux nagios]# tar zxvf nagios-plugins-1.4.9 .tar.gz
[root@linux nagios-plugins-1.4.9 ]# ./configure --prefix=/usr/local/nagios/
(在redhat系统上面安装可能出现configure时，到这里checking for redhat spopen problem...就不动了，所以需要在configure时再加上这个 --enable-redhat-pthread-workaround )
[root@linux nagios-plugins-1.4.9 ]# make
[root@linux nagios-plugins-1.4.9 ]# make install
（3）：配置apache
配置apache的匿名访问：
[root@linux conf.d]# touch nagios.conf | vi nagios
[root@linux apache]# ./bin/htpasswd -c /usr/local/apache/conf.d/htpasswd nagiosadmin
入禁止访问：将apache的用户和组改为nagios。。
如果认证无法通过的话，就查看apache的错误日志，如果出现MySQL ERROR: Table 'test.user_info' doesn't exist: /nagios的提示，就把 http 下的auth_mysql.conf 配置文件该了。不让apache进行mysql认证。
（4）：配置nagios
[root@linux etc]# cp cgi.cfg-sample cgi.cfg
[root@linux etc]# cp commands.cfg-sample commands.cfg
[root@linux etc]# cp nagios.cfg-sample nagios.cfg
[root@linux etc]# cp resource.cfg-sample resource.cfg
[root@linux etc]# vi nagios.cfg
#cfg_file=/usr/local/nagios/etc/localhost.cfg 关闭
开启
cfg_file=/usr/local/nagios/etc/contactgroups.cfg
cfg_file=/usr/local/nagios/etc/contacts.cfg
cfg_file=/usr/local/nagios/etc/dependencies.cfg 此配置文件可以提供先前条件，比如当sina通的情况下，测试业务服务器状态。
cfg_file=/usr/local/nagios/etc/hostgroups.cfg
cfg_file=/usr/local/nagios/etc/hosts.cfg
cfg_file=/usr/local/nagios/etc/services.cfg

[root@linux etc]# touch hostgroups.cfg
[root@linux etc]# touch hosts.cfg
[root@linux etc]# touch services.cfg
[root@linux etc]# touch timeperiods.cfg
[root@linux etc]# vi cgi.cfg

配置完后测试配置是否成功：
服务器的配置文件已复制出来备份。随本文档查看。
[root@linux etc]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
出现：Total Warnings: 0
Total Errors: 0
Things look okay - No serious problems were detected during the pre-flight check
如果配置有错误，可以参考localhost.cfg
表示成功。然后启动：
[root@linux etc]# /usr/local/nagios/bin/nagios -d /usr/local/nagios/etc/nagios.cfg
然后用ie查看结果：
