Nagios http://sourceforge.net/projects/nagios/files/nagios-3.x/nagios-3.2.1/nagios-3.2.1.tar.gz

Nagios-plugins http://prdownloads.sourceforge.net/sourceforge/nagiosplug/nagios-plugins-1.4.15.tar.gz Pnp4nagios http://sourceforge.net/projects/pnp4nagios/files/PNP-0.6/pnp4nagios-0.6.6.tar.gz/download

Nrpe http://prdownloads.sourceforge.net/sourceforge/nagios/nrpe-2.12.tar.gz

注释(以后可能会遇到一下相关包找不到等): 可能yum安装会有些问题找不到包,可添加yum源:如:rpmforge源和epel源

wget http://apt.sw.be/redhat/el6/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm

rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/epel-release-6-5.noarch.rpm

php的一些扩展包找不到就需要添加这两个源:rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm和上面的epel-release-6-5.noarch.rpm

如:php扩展mcrypt就需要epel源;而php的扩展bitset就需要用哦感到rpmforge源。。。

一,安装pnp4nagios

!!!此时安装pnp4nagios就用到了需要的epel源,如果没有epel源

请参考:1、安装epel
# cat /etc/issue
CentOS release 6.2 (Final)
Kernel \r on an \m
# rpm -ivh http://dl.iuscommunity.org/pub/ius/stable/Redhat/6/x86_64/epel-release-6-5.noarch.rpm                         这里应该对应你服务器的版本


  1. [root@master ~]#yum install pnp4nagios rrdtool

或者源码:安装:

在这之前安装rrdtool和pnp4nagios需要如下包:

yum install -y perl-devel perl-CPAN perl-Time-HiRes

#tar -zxvf pnp4nagios-*.tar.gz
#cd php4nagios-*
#./configure --prefix=/usr/local/pnpnagios --with-nagios-user=nagios --with-nagios-group=nagios  (如果单独编译安装的rrdtoool,则使用--with-rrdtool=/usr/local/rrdtool-1.2.xx/bin/rrdtool这样的形式)

#make all
#make install
#make install-webconf
#make install-config
#make install-init

#make fullinstall

(使用这条命令替换所有的make命令, make fullinstall)

还需要:复制所有的pnp4nagios 目录下etc下的*.cfg.simple 复制为*.cfg

cd /usr/local/pnpnagios-*/etc/  
88.  mv misccommands.cfg-sample misccommands.cfg  
89.  mv nagios.cfg-sample nagios.cfg  
90.  mv rra.cfg-sample rra.cfg  
91.  cd pages/  
92.  mv web_traffic.cfg-sample web_traffic.cfg  
93.  cd ../check_commands/  
94.  mv check_all_local_disks.cfg-sample check_all_local_disks.cfg  
95.  mv check_nrpe.cfg-sample check_nrpe.cfg  
96.  mv check_nwstat.cfg-sample check_nwstat.cfg

二,配置nagios

1、修改nagios.cfg


  1. [root@master ~]# vim /etc/nagios/nagios.cfg            //修改以下内容  

  2. process_performance_data=1                             //由0改为1  

  3. host_perfdata_command=process-host-perfdata            //前面的注释拿掉  

  4. service_perfdata_command=process-service-perfdata      //注释拿掉  

  5. enable_environment_macros=1                            //如果有注释拿掉  

2、修改commands.cfg

 注释掉原有对process-host-perfdata和process-service-perfdata,重新定义:


  1. [root@master ~]# vim /etc/nagios/objects/commands.cfg  

  2. define command {  

  3.       command_name    process-service-perfdata  

  4.       command_line    /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl  

  5. }  

  6. define command {  

  7.       command_name    process-host-perfdata  

  8.       command_line    /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA  

  9. }

3、修改配置文件templates.cfg

 添加以下内容


  1. [root@master ~]# vim /etc/nagios/objects/templates.cfg

  2. define host {  

  3. name       hosts-pnp  

  4.        register   0  

  5.        action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_  

  6.        process_perf_data               1  

  7. }  

  8. define service {  

  9. name       srv-pnp  

  10.        register   0  

  11.        action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$  

  12.        process_perf_data               1  

  13. }  

4、修改服务器配置文件cisco_3650.cfg


  1. [root@master ~]# vim /etc/nagios/objects/cisco_3650.cfg

  2. ###### define hosts ##########################

  3. define host{

  4.        use                     generic-switch,hosts-pnp

  5.        host_name               BJ3560G-48

  6.        address                 172.16.1.1

  7.        contact_groups          admins

  8. }

  9. ##### define services ############

  10. define service{

  11.        use                     generic-service,srv-pnp

  12.        host_name               BJ3560G-48

  13.        service_description     PING

  14.        check_command           check_ping!200.0,20%!600.0,60%

  15.        contact_groups          admins

  16. }

三、配置apache

 修改Apache的配置文件httpd.conf:


  1. [root@master ~]# vim /usr/local/apache/conf/httpd.conf  

  2. 在AddType application/x-gzip .gz .tgz下,添加下面的配置项:  

  3. AddType application/x-httpd-php .php  

  4. AddType application/x-httpd-php-source .phps

  5. [root@master ~]# /etc/init.d/httpd restart    重启apache服务

可以直接拷贝下面到vim /etc/httpd/conf.d/pnp4nagios.conf

[root@lvs-save conf.d]# cat /etc/httpd/conf.d/pnp4nagios.conf  

# SAMPLE CONFIG SNIPPETS FOR APACHE WEB SERVER

Alias /pnpnagios "/usr/local/pnpnagios/share"

       AllowOverride None

       Order allow,deny

       Allow from all

       #

       # Use the same value as defined in nagios.conf

       #

       AuthName "Nagios Access"

       AuthType Basic

       AuthUserFile /usr/local/nagios/etc/htpasswd

       Require valid-user

       

               # Turn on URL rewriting

               RewriteEngine On

               Options FollowSymLinks

               # Installation directory

               RewriteBase /pnpnagios/

               # Protect application and system files from being viewed

               RewriteRule ^(application|modules|system) - [F,L]

               # Allow any files or directories that exist to be displayed directly

               RewriteCond %{REQUEST_FILENAME} !-f

               RewriteCond %{REQUEST_FILENAME} !-d

               # Rewrite all other URLs to index.php/URL

               RewriteRule .* index.php/$0 [PT,L]

       

四、如果访问图不出提示:

The requested URL /pnp4nagios/index.php/graph was not found on this server.

那么可能是相关php包没安装:

方法:yum install php*

即可解解以上报错出图问题。

五、如果访问http://IP/pnpnagios需要提供认证而用nagios登录的也不行,那么就执行下一下在生成一个用户进行登录即可!

#htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin  第一次使用htpasswd是用参数-c表示创建目录/usr/local/nagios/etc/htpasswd.users  用于存放用户nagiosadmin 信息!

htpasswd -m /usr/local/nagios/etc/htpasswd.users nagios  这个-m 参数表示在这个文件里面多加一个用户!

注意如果上面配置后在/usr/local/pnpnagios/var/perfdata/ 这么目录下有数据 但是点击游览器访问出图数据时候报错说什么找不到主机图,那么一般是http配置问题!看看pnp4nagios和pnpnagios区别的别名问题!
