python-Django監控系統二次開發Nagios

標籤：

1、Nagios安裝

yum install -y nagios.i686

yum install -y nagios-plugins-all.i686

安裝完後會在apache的設定檔目錄下/etc/httpd/conf.d/產生一個外部的設定檔nagios.conf

service httpd start

service nagios start

default user nagiosadmin password nagiosadmin

2.設定檔產生器

Django前期的收集主機資訊代碼

在nagios上分組
