基于FreeBSD+nagios下的系统告警系统
-----------------------------------主要软件应用-------------------------
FreeBSD apache22 php5 php5-extension Ngios Nagios-plugin Nrpe NSCclient++
-----------------------------------------系统安装-------------------------
1.
FreeBSD采用最小化安装
2.
更新ports
# portsnap fetch
#portsnap extract
---------------------------------------------软件安装------------------------
1.
Nagios
# cd /usr/ports//net-mgmt/nagios/
# make instal clean
//此过程会询问建立用户和组nagios
2.
Nagios-plugin
# cd /usr//net-mgmt/nagios-plugin/
# make install
3.
NRpe 下载地址为：
http://www.nagios.org/download/addons
//如果所要监控的服务器中有linux，不要直接使用ports 安装，因为ports安装过后，其格式为check_nrpe2, 但是linux 采用源码安装的为check_nrpe. 从而导致两者之间不能通信
# cd /usr/local
# tar zxvf nrpe-2.12.tar.gz
# cd nrpe-2.12
# ./configure
# make
# make install
网页服务器的安装请参考前人的文章
------------------------------------------------配置文件-------------------------

查看/var/spool/nagios/下有没如下文件或文件夹，没则建立
