第一步 : 安装 nagios
首先禁用 AppArmor
/etc/init.d/apparmor stop
update-rc.d -f apparmor remove
aptitude remove apparmor apparmor-utils
安装必须库 和 更新系统
aptitude -y install apache2 libapache2-mod-php5 build-essential libgd2-xpm-dev postfix
# aptitude update -> GCC编译器与开发库
# postfix -> 邮件apt-get update
apt-get upgrade
设置 用户和组
useradd -m -s /bin/bash nagios
passwd nagios
usermod -G nagios nagios
groupadd nagcmd
usermod -a -G nagcmd nagios
下载/解压nagios与其插件
cd /downloads
wget http://prdownloads.sourceforge.net/nagios/nagios-3.2.3.tar.gz
wget http://prdownloads.sourceforge.net/nagiosplug/nagios-plugins-1.4.15.tar.gz
tar -zxf /downloads/nagios-3.2.3.tar.gz
或 tar jxvf /downloads/nagios-3.2.3.tar.bz2
tar -zxf /downloads/nagios-plugins-1.4.15.tar.gz
安装 nagios
cd /downloads/nagios-3.2.3
./configure –with-command-group=nagcmd
make all
make install
make install-init
make install-config
make install-commandmode
make install-webconf
nagios密码(没理解到)
This is the password you will need to look at the nagios pages. If you install Nagios to a different directory please change this command to where the Nagios etc. folder will be.
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
重启apache2
/etc/init.d/apache2 restart
第二步 安装nagios插件
cd /downloads/nagios-plugins-1.4.15/
./configure
make
make install
现在把 nagios加入启动
ln -s /etc/init.d/nagios /etc/rcS.d/S99nagios
修改默认nagios admin email
nano /usr/local/nagios/etc/objects/contacts.cfg
修改
nagios@localhost 到 You@yourdomain.com
检验nagios配置文件是否正常,可以有警告,但是不能有任意一个错误.
/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
正常的话 就可以启动了
/etc/init.d/nagios start
现在你可以通过 http://yourserver/nagios/ 查看界面了
第三步 配置一个需监控的windows机器
下载 NSClient++
http://sourceforge.net/projects/nscplus/files/latest/download
安装脚本:
#!/bin/bash
