nagios安装
下载：wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.2.0.tar.gz
安装：
tar -zxvf nagios-3.2.0.tar.gz
cd nagios-3.2.0
./configure –prefix=/usr/local/nagios –with-command-group=nagcmd
make all
make all完毕后有如下提示：
“If the main program and CGIs compiled without any errors, you
can continue with installing Nagios as follows (type ‘make’
without any arguments for a list of all possible options):
make install
– This installs the main program, CGIs, and HTML files
make install-init
– This installs the init script in /etc/rc.d/init.d
make install-commandmode
– This installs and configures permissions on the
directory for holding the external command file
make install-config
– This installs *SAMPLE* config files in /usr/local/nagios/etc
You’ll have to modify these sample files before you can
use Nagios. Read the HTML documentation for more info
on doing this. Pay particular attention to the docs on
object configuration files, as they determine what/how
things get monitored!
make install-webconf
– This installs the Apache config file for the Nagios
web interface”
依次运行如下命令:
make install
make install-init
make install-commandmode
make install-config
make install-webconf
给nginx添加认证：
修改nginx的配置文件如下：
location /nagios/ {
alias /usr/local/nagios/share/;
index index.html index.htm index.php;
auth_basic “nagios”;
auth_basic_user_file /usr/local/nagios/etc/htpasswd admin
}
生成htpasswd文件：
/usr/bin/htpasswd -c /usr/local/nagios/etc/htpasswd admin
其中htpasswd是apache提供的工具
配置nagios
nagios web界面提示
It appears as though you do not have permission to view information for any of the services you requested…
打开cgi.cfg配置文件，里面有个参数:
use_authentication=1
为了保障系统的安全性，nagios设置了这个参数，默认为1,改为0即可
配置：
下载插件：
wget http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.13.tar.gz
tar -zxvf nagios-plugins-1.4.13.tar.gz
cd nagios-plugins-1.4.13

tar -zxvf nrpe-2.12.tar.gz
cd nrpe-2.12
./configure –prefix=/usr/local/nagios
make all
make install-plugin
make install-daemon
make install-daemon-config
/usr/local/nagios/bin/nrpe -c /usr/local/nagios/etc/nrpe.cfg -d
返回：[root@localhost nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H localhost
NRPE v2.12
完成。
