nagios&pnp4nagios--yum 安装

一。环境：

1. centos 6.4

2. 设置hostname 并且安装好apache

3. 关闭selinux及iptables

二。安装nagios服务器端：

1. rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

2. yum -y install nagios nagios-plugins-all nagios-plugins-nrpe nrpe php

3. chkconfig httpd on && chkconfig nagios on

4. service httpd start && service nagios start

5. 设置nagiosadmin密码：

htpasswd -c /etc/nagios/htpasswd.users nagiosadmin

6. 登陆：开浏览器，输入密码，在host里面应该有“localhost”这台机器
http://{your_ip_address}/nagios

三。安装pnp4nagios：

1. yum install pnp4nagios rrdtool

四。配置pnp4nagios：

1，修改nagios.cfg

[root@localhost objects]# vim /etc/nagios/nagios.cfg //修改以下内容
process_performance_data=1 //由0改为1
host_perfdata_command=process-host-perfdata //前面的注释拿掉
service_perfdata_command=process-service-perfdata //注释拿掉
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

[root@localhost objects]# vim /etc/nagios/objects/commands.cfg
define command {
command_name process-service-perfdata
command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl
}
define command {
command_name process-host-perfdata
command_line /usr/bin/perl /usr/libexec/pnp4nagios/process_perfdata.pl -d HOSTPERFDATA
}

3、修改配置文件templates.cfg

[root@localhost objects]# vim /etc/nagios/objects/templates.cfg
define host {
name hosts-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=_HOST_
process_perf_data 1
}
define service {
name srv-pnp
register 0
action_url /pnp4nagios/index.php/graph?host=$HOSTNAME$&srv=$SERVICEDESC$
process_perf_data 1
}

4，修改服务器配置文件localhost.cfg

[root@localhost objects]# vim /etc/nagios/localhost.cfg
define host{
use linux-server,hosts-pnp
host_name localhost
alias localhost
address 127.0.0.1
}
define service{
use local-service,srv-pnp
host_name localhost
service_description PING
check_command check_ping!100.0,20%!500.0,60%
}

上面只是例举了一个，你可以都加一下。

在网上好多关于pnp4nagios的文章，都是要把mv misccommands.cfg-sample misccommands.cfg 生成配置文件，我是yum安装的，安装目录下根本没有sample这样的东西

[root@localhost objects]# tree /etc/pnp4nagios/
/etc/pnp4nagios/
├── background.pdf
├── check_commands
│ ├── check_all_local_disks.cfg
│ ├── check_nrpe.cfg
│ └── check_nwstat.cfg
├── config.php
├── misccommands.cfg
├── nagios.cfg
├── npcd.cfg
├── pages
│ └── web_traffic.cfg
├── pnp4nagios_release
├── process_perfdata.cfg
└── rra.cfg

所在我根本没有配置任何东西。

5，重启nagios，启动npcd

[root@localhost pnp4nagios]# /etc/init.d/npcd start
[root@localhost pnp4nagios]# /etc/init.d/nagios restart

五。登陆错误处理：

登陆http://{your_ip_address}/nagios，发现密码认证不对，请修改以下内容：

vi /etc/httpd/conf.d/pnp4nagios.conf

把 AuthUserFile /etc/nagios/passwd 修改为

AuthUserFile /etc/nagios/htpasswd.users

完工，小太阳可以看到，并且点击开来。

六。配置调试命令

/usr/bin/nagios -v /etc/nagios/nagios.cfg

[root@nagios-mendian mendian]# /usr/bin/nagios -v /etc/nagios/nagios.cfg
