配置apache web服务器：
将现面行加入apache配置文件的alias模块
        ----------------------------------------------------------
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"


#  SSLRequireSSL
   Options ExecCGI
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
   AuthName "Nagios Access"
   AuthType Basic
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
   Require valid-user


Alias /nagios "/usr/local/nagios/share"


#  SSLRequireSSL
   Options None
   AllowOverride None
   Order allow,deny
   Allow from all
#  Order deny,allow
#  Deny from all
#  Allow from 127.0.0.1
   AuthName "Nagios Access"
   AuthType Basic
   AuthUserFile /usr/local/nagios/etc/htpasswd.users
   Require valid-user

        ----------------------------------------------------------

＃ 创建密码目录验证文件
/usr/local/apache/bin/htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password: (输入密码)
Re-type new password: (再输入一次密码)
Adding password for user nagiosadmin

# 配置nagios配置文件
vi /usr/local/nagios/etc/objects/contacts.cfg
# 将里面的email地址改为自己的email地址。
安装Nagios插件
tar xzf nagios-plugins-1.4.11.tar.gz
cd nagios-plugins-1.4.11
./configure --with-nagios-user=nagios --with-nagios-group=nagios
make
make install

＃＃启动Nagios
＃ 配置机器启动时自动启动Nagios
chkconfig --add nagios
chkconfig nagios on
＃ 检查Nagios配置文件
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
＃ 启Nnagios
service nagios start

8.安装nrpe插件，用来监控Linux机器
tar xzvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure
make all
＃ 在Nagios服务器端只要安装nrpe监控插件就行
make install-plugin
在/usr/local/nagios/etc/objects/commands.cfg中定义check_nrpe命令
vi /usr/local/nagios/etc/objects/commands.cfg
########################################################################
#
# 2008.11.18 add by Stone
# NRPE COMMAND
#
########################################################################
# 'check_nrpe ' command definition
define command{
        command_name check_nrpe
        command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
        }

＃ 修改nrpe配置文件，允许Nagios监控服务器（192.168.0.19）监控
vi nrpe.cfg
＃ 多台机器用逗号隔开
allowed_hosts=127.0.0.1,192.168.0.19
＃ 以独立守护进程启动nrpe，也可以使用xinetd启动nrpe，具体清查看nrpe官方文档。
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
＃ 开机自动启动nrpe
vi /etc/rc.d/rc.local
＃ 加入下面行
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
＃ 检查nrpe是否安装正常
[root@wiki etc]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12
＃ 返回nrpe版本说明安装没问题。
＃ 查看启动端口
[root@wiki ~]# netstat -tunlp
