nagios 安装过程

首先要安装apache。要启用cgi模块。

 

一、下载最新的软件包nagios-3.0.tar.gz

   wget

   tar zxvf nagios-3.0.tar.gz

   cd nagios-3.0

   mkdir /usr/local/nagios

   useradd -s /sbin/nologin nagios

   chown nagios.nagios /usr/local/nagios

   ./configure --prefix=/usr/local/nagios

   make

   make install

   make install-init
   make install-commandmode
   make install-config

 

二、安装nagios-plugs

   wget

   tar zxvf nagios-plugins-1.4.11.tar.gz

   cd nagios-plugs-1.4.11

   ./configure --prefix=/usr/local/nagios

   make

   make install

   vi /usr/local/apache/conf/httpd.conf

   添加：

    ScriptAlias /nagios/cgi-bin /usr/local/nagios/sbin

    Options ExecCGI
    AllowOverride None
    Order allow,deny
    Allow from all
    AuthName "Nagios Access"
    AuthType Basic
    AuthUserFile /usr/local/nagios/etc/passwd
    Require valid-user

Alias /nagios /usr/local/nagios/share

    Options None
    AllowOverride None
    Order allow,deny
    Allow from all
    AuthName "Nagios Access"
    AuthType Basic
    AuthUserFile /usr/local/nagios/etc/passwd
    Require valid-user

##############################

  htpasswd -c /usr/local/nagios/etc/passwd nagiosadmin

/usr/local/apache/bin/apachectl restart

/etc/init.d/nagios start

 

就可以访问到默认的监控本机的服务了。接下来就可以装其他的插件了，休息一下再来。

 

三、安装nrpe

 

wget

tar xzf nrpe-2.8.tar.gz
cd nrpe-2.8

./configure
make all

make install-plugin
make install-daemon
make install-daemon-config

make install-xinetd
Edit the /etc/xinetd.d/nrpe file and add the IP address of the monitoring server to the only_from directive.

only_from = 127.0.0.1
Add the following entry for the NRPE daemon to the /etc/services file.
nrpe 5666/tcp # NRPE
Restart the xinetd service.

vi /etc/services

增加：

nrpe     5666/tcp    #nrpe

 

service xinetd restart

netstat -at | grep nrpe
The output out this command should show something like this:
tcp 0 0 *:nrpe *:* LISTEN

 

然后修改防火墙的规则：

iptables -I RH-Firewall-1-INPUT -p tcp -m tcp –dport 5666 -j ACCEPT

service iptables save

 

vi /usr/local/nagios/etc/nrpe.cfg

 

/usr/local/nagios/libexec/check_nrpe -H localhost -c check_users
/usr/local/nagios/libexec/check_nrpe -H localhost -c check_load
/usr/local/nagios/libexec/check_nrpe -H localhost -c check_hda1
/usr/local/nagios/libexec/check_nrpe -H localhost -c check_total_procs
/usr/local/nagios/libexec/check_nrpe -H localhost -c check_zombie_procs
