nagios系列(一)centos6.5环境部署nagios服务端

nagios软件安装包存放目录：/home/oldboy/tools

nagios服务安装目录：/usr/local/nagios





1、配置yum源

echo "------ step 1: config yum ------"

cd /etc/yum.repos.d/

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo





报错：

# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo

--2016-07-21 09:10:05--  http://mirrors.aliyun.com/repo/Centos-6.repo

Resolving mirrors.aliyun.com... failed: Name or service not known.

wget: unable to resolve host address “mirrors.aliyun.com”

是不能解析域名，编辑DNS即可

[root@node4 yum.repos.d]# vim /etc/resolv.conf 

nameserver 192.168.8.251

setenforce 0

fi

crontab -l
