nagios 安装

www.nagios.org  下载nagios nagios-plugs nrpe

www.apache.org   下载apache

 

 

1）  安装apache

进入tar包解压路径(tar.gz zxvf 选项解压 tar.bz jxvf选项解压)

cd /usr/httpd-2.2.11

安装

./configure --prefix=/usr/local/apache && make && make install

在安装完nagios后在/usr/local/apache/conf/httpd.conf添加

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

 <Directory "/usr/local/nagios/sbin">

         AuthType Basic

         Options ExecCGI

         AllowOverride None

         Order allow,deny

         Allow from all

         AuthName "Nagios Access"

         AuthUserFile /usr/local/nagios/etc/htpasswd

         Require valid-user

 </Directory>

 

 Alias /nagios /usr/local/nagios/share

 <Directory "/usr/local/nagios/share">

         AuthType Basic

         Options None

         AllowOverride None

         Order allow,deny

         Allow from all

         AuthName "nagios Access"

         AuthUserFile /usr/local/nagios/etc/htpasswd

         Require valid-user

 </Directory>

或者用Include /usr/nagios-3.06/sample-config/httpd.conf  方式添加

2)安装nagios

   cd /usr/nagios-3.0.6  (nagios 3.1版本tar包有些问题，安装后不能访问目前建议使用低版本)

安装

 a)添加nagios用户

adduser nagios

b）执行安装命令

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

make all
make install        
make install-init     ##This installs the init
make install-commandmode  
make install-config    ##将初始的配置文件安装到/usr/local/nagios/etc

 

3）安装nagios-plugs

 

./configure --prefix=/usr/local/nagios/ --enable-redhat-pthread-workaround（此选项针对redhat）

make all
make install

 

4）安装nrpe测试本地

./configure

make all

Install the NRPE plugin (for testing), daemon, and sample daemon config file.

make install-plugin

make install-daemon

make install-daemon-config

Install the NRPE daemon as a service under xinetd.

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 = 127.0.0.1 210.51.4.114 <nagios_ip_address>

Add the following entry for the NRPE daemon to the /etc/services file.

nrpe 5666/tcp # NRPE

Restart the xinetd service.

service xinetd restart

5）测试nrpe情况

# netstat -at|grep nrpe

tcp        0      0 *:nrpe                  *:*                     LISTEN   

# netstat -an|grep 5666

tcp        0      0 0.0.0.0:5666            0.0.0.0:*               LISTEN  

可以看到5666端口已经在监听了

 

6）执行

/usr/local/nagios/libexec/check_nrpe -H localhost

测试nrpe是否正常工作

7）执行下面命令检查nagios配置

/usr/local/nagios/bin/nagios �Cv /usr/local/nagios/etc/nagios.cfg

7）执行下面命令启动nagios

 

/usr/local/nagios/bin/nagios �Cd /usr/local/nagios/etc/nagios.cfg

 

8）为nagios登录界面添加用户及密码

/usr/local/apache/bin/htpasswd �Cc /usr/local/nagios/etc/htpasswd nagios

9）修改/usr/local/nagios/etc/cgi.cfg

default_user_name=nagios

更改文件内的nagiosadmin为nagiosadmin,nagios

10）chmod 777 /usr/local/nagios/var/rw/nagios.cmd

chmod 777 /usr/local/nagios/var/rw

11）启动apache

/usr/local/apache/bin/apachectl start

通过http://192.168.1.12/nagios 访问nagios

 

12)添加开机自启动

echo “/usr/local/apache/bin/apachectl start”  >>  /etc/rc.local

echo “/usr/local/nagios/bin/nagios �Cd /usr/local/nagios/etc/nagios.cfg”  >>  /etc/rc.local
