nagios安装配置
系统要求
The only requirement of running Nagios is a machine running Linux (or UNIX variant) and a C compiler. You will probably also want to have TCP/IP configured, as most service checks will be performed over the network. You are not required to use the CGIs included with Nagios. However, if you do decide to use them, you will need to have the following software installed...
1。A web server (preferrably Apache)
2。Thomas Boutell's gd library version 1.6.3 or higher (required by the statusmap and trends CGIs)
软件主页：
+ 1.下载源码包
wget http://nchc.dl.sourceforge.net/sourceforge/nagios/nagios-2.0b3.tar.gz
2.解压源码包
tar xfvz nagios-2.0b3.tar.gz
3.配置编译
cd nagios-2.0b3
adduser nagios
mkdir /usr/local/nagios
chown nagios.nagios /usr/local/nagios
grep "^User" /usr/local/apache2/conf/httpd.conf
/usr/sbin/groupadd nagcmd
/usr/sbin/usermod -G nagcmd nobody
/usr/sbin/usermod -G nagcmd nagios
./configure --prefix=/usr/local/nagios --with-cgiurl=/nagios/cgi-bin \
--with-htmlurl=/nagios --with-nagios-usr=nagios --with-nagios-group=nagios \
--with-command-group=nagcmd --with-gd-lib --enable-embedded-perl \
--with-perlcache make all
make install
make install-init
make install-commandmode
make install-config
安装nagios-plugs 1.下载源码包
wget http://nchc.dl.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.tar.gz
2.解压源码包
tar xfvz nagios-plugins-1.4.tar.gz
3.配置编译
./configure --prefix=/usr/local/nagios --with-mysql --with-cgiurl
make
make install
配置apache ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin" AllowOverride AuthConfig
Options ExecCGI
Order allow,deny
Allow from all
Alias /nagios "/usr/local/nagios/share" Options None
AllowOverride AuthConfig
Order allow,deny
Allow from all
Authorization In The CGIs
The second step is to create a file named .htaccess in the root your CGI directory (and optionally also you HTML directory) for Nagios (usually /usr/local/nagios/sbin and /usr/local/nagios/share, respectively). The file(s) should have contents similiar to the following... : cd /usr/local/nagios/sbin
vi .htaccess AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
require valid-user cd /usr/local/nagios/share
vi .htaccess AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
require valid-user
Setting Up Authenticated Users: htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
格式：
htpasswd -c /usr/local/nagios/etc/htpasswd.users
Enabling Authentication/Authorization Functionality In The CGIs
The next thing you need to do is make sure that the CGIs are configured to use the authentication and authorization functionality in determining what information and/or commands users have access to. This is done be setting the use_authentication variable in the CGI configuration file to a non-zero value. Example: vi /usr/local/nagios/etc/cgi.cfg
use_authentication=1 /usr/local/apache2/bin/apachectl restart
配置文件 一. nagios.cfg
首先，刚装好的nagios,在/usr/local/nagios/etc 下，文件都是以-sample结尾的，要把某些文件去掉- sample。
主配置文件 nagios.cfg
mv nagios.cfg--sample nagios.cfg
vi nagios.cfg
注释这句话
#cfg_file=/usr/local/nagios/etc/minimal.cfg
在 # OBJECT CACHE FILE 这句话前面添加如下语句
cfg_dir=/usr/local/nagios/etc/hosts
cfg_dir=/usr/local/nagios/etc/contacts
cfg_dir=/usr/local/nagios/etc/services
cfg_dir=/usr/local/nagios/etc/commands 存盘退出 mkdir hosts
mkdir contacts
mkdir services
mkdir commands 这样做，主要是为了分类，管理方便。
有些cfg文件可以参照 bigger.cfg-sample，minimal.cfg-sample 这两个文件 cd hosts
