安装依赖包：（其实不装也能安装成功，就是部分功能会disabled）
|
1 2 |
sudo apt-get install build-essential libssl-dev \ libgd2-xpm-dev libpng12-dev php5-gd libgd2-xpm |
用户组：
|
1 2 3 4 |
sudo adduser --system --no-create-home --disabled-login --group nagios sudo groupadd nagcmd sudo usermod -G nagcmd nagios sudo usermod -a -G nagcmd www-data |
从 http://www.nagios.org/download/ 下载解压：
|
1 2 3 4 5 6 7 |
cd /tmp mkdir nagios cd nagios wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-4.0.5.tar.gz wget http://www.nagios-plugins.org/download/nagios-plugins-2.0.1.tar.gz tar zxf nagios-4.0.5.tar.gz tar zxf nagios-plugins-2.0.1.tar.gz |
编译安装：
|
1 2 3 4 5 6 7 8 9 |
cd /tmp/nagios/nagios-4.0.5 ./configure --prefix=/opt/nagios --sysconfdir=/etc/nagios \ --with-nagios-user=nagios --with-nagios-group=nagios \ --with-command-user=nagios --with-command-group=nagcmd make all sudo make install sudo make install-init sudo make install-config sudo make install-commandmode |
建立htpasswd.users，这个如果装了apache2有htpasswd这个命令，不然可以用某个python脚本：
（如果服务器不想装python，可以找台有python的服务器；或者找台装了apache的机器运行htpasswd；或者装个httpd不启动也没关系）
（生成的htpasswd.users是个文本文件，复制到服务器的 /etc/nagios/htpasswd.users）
|

wget http://trac.edgewall.org/export/10791/trunk/contrib/htpasswd.py chmod +x htpasswd.py ./htpasswd.py -c -b /etc/nagios/htpasswd.users nagiosadmin "password" |
修改联系人email，在contacts.cfg的email那里（34行）
|
1 |
sudo vi /etc/nagios/objects/contacts.cfg |
安装mail报警通知所需包（安装时选择”Internet Site”；输入域名）
